## Feedback
This is a first public test, so reports are really useful, especially from
Windows and Linux. The quickest way is the
[feedback form](https://frame-control.pages.dev/feedback/): no GitHub account
needed, and it opens an issue here. Please include:
Windows and Linux. The quickest way is **Report a problem** in the app (the
warning-sign button at the top, or **Help → Report a Problem…**). It adds
diagnostics with personal details removed, shows you exactly what's included,
and sends it privately to the maintainer; nothing is published. Without the app,
use the [feedback form](https://frame-control.pages.dev/feedback/). Please include:
- what you tried and what happened
- your computer's OS and your SteamOS build (Steam Settings → System)

// asset before anything is replaced. How the update is applied:
// macOS the .zip: unpacked next to the running app, swapped in by a small
// script once the app has quit, then reopened.
// Windows the NSIS installer, run silently over the current install; it
// reopens the app. A copy unpacked from the .zip is updated by hand.
// Linux the AppImage replaces itself; .deb installs are updated by hand.

# compat-db: Frame Control's compatibility database
A private [Lakebed](https://docs.lakebed.dev/) capsule holding compatibility
reports for Android apps on the Steam Frame. For now only the maintainer's
copy of Frame Control has the key to read or write it. Everyone else's reports
stay on their own Mac (see `shared()` in `ui/frame_compat_db.py`).
reports for Android apps on the Steam Frame. Only the maintainer's copy of
Frame Control has the key to read or write it (see `shared()` in
`ui/frame_compat_db.py`). Everyone else's reports stay on their computer
unless they turn on **Share compatibility results**. Then the reports also go
to PostHog as `compat_report` events, and the maintainer syncs them in (below).
## Community reports
```sh
python3 ui/frame_compat_db.py sync --dry-run # what would be added
python3 ui/frame_compat_db.py sync # add them
```
`sync` reads `compat_report` events through PostHog's query API and adds
them with `via` set to `community`, `community-probe` or `community-install`.
It skips invalid reports and anything over 30 per reporter per day. Each run
re-reads the last 30 days, because an offline copy sends its reports late,
with the time they were made. `posthog-sync.json`, next to the outbox,
remembers which reports it has handled and each reporter's daily count, so
nothing is added twice and the cap holds across runs.
It needs:
- the PostHog project id: `"project"` in `ui/telemetry.json`
- a personal API key with `query:read`: `POSTHOG_PERSONAL_API_KEY`, or in the
Keychain (service `frame-control-posthog`, account `personal-api-key`)
- Live: `https://frame-compat.lakebed.app` (deploy `dep_dDmcsosVSiFirpW6`,
claimed, so it doesn't expire). The browser page only says it's private.

# Frame Control for AI agents
**Documented interface:** Frame Control's own stdlib Python MCP adapter wraps
its loopback HTTP API. No API key, hosted service, model SDK or third-party
helper app is needed. The assistant is our HTML/Python implementation hosted
in the platform Chromium browser. Its optional LLM endpoint is user configuration.
Installing other apps is an optional management action, never a prerequisite.
## Connect an MCP client
The default MCP command starts a private HTTP backend on a free loopback port,
with a fresh local access key. It stops that backend when the MCP client closes
stdin or sends SIGTERM. It uses its own SSH control socket, so closing it does
not close the desktop app's connection. No manually started server is needed.
Add this stdio server to your MCP client (use absolute paths):
```json
{
"mcpServers": {
"frame-control": {
"command": "python3",
"args": ["/absolute/path/frame-control/ui/frame_mcp.py"]
}
}
}
```
For Codex, the equivalent registration is:
```sh
codex mcp add frame-control -- python3 /absolute/path/frame-control/ui/frame_mcp.py
```
New agent sessions load the entry. An already running session may need its MCP
connections reloaded; registration does not retroactively add tools to its
initial tool inventory. Keep the checkout at that path while it is registered.
Use `codex mcp remove frame-control` to remove only this registration.
To reuse a running server instead, pass `--url http://127.0.0.1:47810`.
The desktop app uses a random port; use that port with `--url`, or run the
checkout server above. If the HTTP server uses `FRAME_UI_KEY`, pass the same
value in the MCP process environment. This is local access control, not an LLM
API key. The adapter only accepts loopback HTTP servers, refuses redirects and
ignores environment proxies. Stdout contains newline-delimited JSON-RPC only.
It supports MCP initialization, ping, tool listing and tool calls; no sampling,
resources, prompts or streaming transport.
| Tool | Arguments | Effect |
|---|---|---|
| `computer_state` | none | Read-only gamescope window IDs/focus and bounded AT-SPI tree; reports incomplete observations |
| `status` | none | Battery, services, installed games and Flatpaks |
| `screenshot` | `view`: `headset` (default) or `desktop` | Returns PNG image content to the MCP client |
| `job` | `id` | Background install status; poll until `done`, inspect `error` |
| `launch` | `appid` | Launch an installed Steam app |
| `install` / `uninstall` | `id` | Install from Flathub / remove a user Flatpak |
| `send_text` | `text` | Frame desktop clipboard; desktop must be open |
| `send_file` | `path` | File on the HTTP server computer, up to 16 MiB, copied to Frame `~/Downloads` |
| `panel` | `id` | Launch an installed Flatpak as a panel using the existing launcher |
| `power` | `action`: `suspend`, `reboot`, `poweroff` | Open a terminal for the user to enter the sudo password |
| `keep_awake` | `action`: `on`, `off`, `status` | Optional keep-awake script interface |
Only install free software with its developer's consent. There is no purchase,
entitlement bypass or arbitrary shell tool. `install` returns a background job
ID; it does not claim the installation has finished. APK and sideloaded title
installs remain in the main UI for now.
### Approval is a separate human action
Every mutation first returns an `approvalUrl`, exact action and `confirmation`
token. Ask the user to open that URL and choose **Approve this action** or
**Reject**. Then repeat the same tool and arguments with the token in
`confirmation`. The server refuses execution before approval, changed arguments,
expired tokens and reuse. A file approval binds the content hash as well as the
path. Approvals last five minutes and disappear when the HTTP server restarts.
A failed execution also consumes the approval; review a fresh request to retry.
The panel does not execute an action merely because it was approved.
MCP has no approval tool. This is protection against accidental model tool
calls, not a sandbox against a client with independent shell/HTTP access to your
computer. Grant the MCP client only the access you intend. Status, captures and computer-state observations
are returned directly to that client, which may forward them to its configured
model. The assistant's separate opt-in does not govern an external MCP client.
Power still requires the existing password prompt in a local terminal. MCP
never receives passwords. Power via `FRAME_LOCAL=1` is unsupported: use the main
UI. The panel launcher and keep-awake adapter require zsh on the computer.
[PR #16](https://github.com/saphid/frame-control/pull/16) owns
`scripts/keep-awake.sh on|off|status`. This branch does not copy or change it.
Until that script is present, the tool reports it unavailable. Keep-awake is
never automatic: `on` changes the shared idle timers; explicitly approve `off`
to restore them after work. It is not a per-agent lease; coordinate with other
users. No changes are made to the analytics/update interfaces in
[PR #17](https://github.com/saphid/frame-control/pull/17). Prompts, keys, model
replies, screenshots and approval payloads are not sent to analytics.
## Assistant panel
Open **Tools → Open assistant**, or `http://127.0.0.1:47810/assistant`.
To put the same page in the headset, with the HTTP server still running:
```sh
python3 scripts/assistant-on-frame.py --port 47810
```
This starts an SSH reverse forward bound to Frame loopback (port 47812 by
default), then a dedicated Chromium profile tagged as a SteamVR panel. Keep the
command running. Ctrl-C closes this browser profile and the tunnel; it leaves
other Chromium windows and the existing HTTP server alone. A failed cleanup
prints the temporary profile path so it can be removed when the Frame returns.
Use `--frame-port` if the default is busy. Chromium must already be available as
`org.chromium.Chromium`; the launcher never installs anything automatically.
Place the panel with SteamVR's normal docking controls.
Enter your full **chat-completions endpoint**, model name and optional key.
An OpenAI-compatible local server works without a key; no OpenAI account is
required. HTTP is allowed only on loopback; other endpoints require HTTPS.
Loopback refers to the computer running the HTTP server, even in the headset.
Endpoints with embedded credentials, query strings or redirects are refused.
Check the message consent box and press **Send message**. Screenshot context is
a separate unchecked box and sends one fresh capture with that request. Both
boxes reset after sending, and changing endpoint/model revokes consent. Nothing
is sent when opening the page or entering configuration. There is no model
list fetch, saved history, automatic screenshot capture or assistant telemetry.
Each send is independent: previous messages and replies are not included.
Configuration, credentials and chat remain in page memory; close/reload the page
or choose **Clear everything** to clear them. A request already sent cannot be
recalled. Only the chosen endpoint gets the request; proxy environment variables
and redirects are disabled. Its privacy and retention policy still applies.
Replies are plain text and cannot call tools or operate the Frame. A model must
support image inputs to accept screenshot context.
## Evidence and limits
**Verified 2026-09-28, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** loopback HTTP
status through an SSH reverse tunnel; platform Chromium created a separate
SteamVR panel (confirmed in `GAMESCOPE_FOCUSABLE_APPS`); headset capture returned
a PNG. These checks preceded the UI implementation. No power or global settings
were changed.
**Inferred:** visual comfort and controller keyboard usability while wearing
the headset; panel creation in gamescope alone does not establish these.
Windows/Linux launcher support, live third-party model endpoints, installs,
uninstalls, power and keep-awake changes are not covered by that feasibility
check. See the PR for the final unit and end-to-end results.
**Verified end to end on the same Frame/build (2026-09-28):** a stdio MCP client
initialized, read status, retrieved a headset PNG, and transferred a test file
only after approval through the Chromium page. Remote file bytes matched;
reusing the confirmation was rejected. The actual headset Chromium page sent
text and then separately opted-in image context to a local test endpoint and
displayed its replies. Without consent there were zero endpoint requests.
The test endpoint returned canned replies: model inference and a live external
provider remain **unverified**. The launcher’s Ctrl-C cleanup was checked;
profiles, SSH tunnels and the test file were removed. No installs, removals,
launches of user games, power operations or keep-awake changes were performed.
**Verified locally:** unit coverage includes the stdio subprocess, approval
binding/expiry/replay/concurrency, file-change rejection, and a real local HTTP
endpoint for opt-in, text/image payloads and redirect refusal. Fake-Frame
regressions are in `tests/e2e/test_agents.py`; local Docker execution was blocked
because the Docker daemon was unavailable. The ARM64 fake-Frame CI job passed
on this branch (run 36421345682).
**Verified on the same Frame/build:** both Ctrl-C and SIGTERM close the dedicated
browser profile and SSH tunnel and remove the profile and panel log.
![Assistant in Frame Chromium, after an opted-in request to the local test endpoint](img/assistant-panel.png)
## Computer-use coverage
MCP is the tool transport, not a limit on what an agent can do. A screenshot,
accessibility snapshot, click or keystroke can all be MCP tools when we have a
reliable underlying implementation. See [the investigation](computer-use.md)
for the verified boundaries. `computer_state` adds observation, not an input
channel: it cannot click an approval button or send keyboard/mouse events.
**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** the command saved
by `codex mcp add` launched without a prestarted server, negotiated MCP, listed
12 tools, read live Frame status and returned X11 window state plus AT-SPI
observations. It exited 0 at EOF. Steam's accessibility tree had inaccessible
children, reported as `incomplete: true`; this is not a complete actionable UI.

# Announcing changes
How we tell people about Frame Control features and fixes as they merge. The
same few sentences feed the X post, the release notes and the website, so they
are written once, in the pull request, while the change is fresh.
## What gets announced
| Kind | Announce? | Example |
|---|---|---|
| **New** — something you can now do | Yes, its own post | Stream Mac windows into the Frame as panels |
| **Better** — something existing got noticeably easier, faster or wider | Yes, its own post or a roundup | APKs install without the Android SDK |
| **Fixed** — something broken that users hit | Yes if people reported it or it blocked a flow; otherwise the next roundup | Mac mirror showed a zoomed-in corner |
| **Release** — a tagged build | Always, one post linking the release | Frame Control 0.3.1 |
| Tests, refactors, CI, docs-only, website polish | No | Fake Frame tests, screenshot crop |
If a change isn't worth a sentence to someone who owns a Frame, it isn't
announced.
## The voice
Write it the way the README and release notes already read.
- **Lead with what the person can now do**, in their words: "Install older
versions of an app when the newest won't run on the Frame", not "Add APK
version fallback resolver".
- **Plain and specific.** Name the thing, give the number: "about 30 fps",
"4,500 apps", "up to 8 older versions". No "blazing", "game-changing",
"excited to announce", "huge", or exclamation marks.
- **Say where it works.** Platforms and what it was tested on, briefly:
"Tested on a real Frame from macOS 27." Don't claim what wasn't tested.
- **Say the catch.** If it needs a setup step, an unsigned build, or only works
on one OS, say so in the same post.
- **Sentence case**, full sentences, British spelling to match the docs.
Contractions are fine.
- **No emoji in the text.** One image, GIF or short clip carries the tone
instead. The only symbol is the kind label below.
- **Unofficial, always.** Never imply Valve made or endorses it. Say "Steam
Frame" for the headset and "Frame Control" for the app.
- **Credit people.** If a user reported the bug or suggested the feature and is
happy to be named, thank them by handle.
## The formats
Every announceable PR ends with an `## Announcement` section holding these.
The reviewer checks it like code.
### 1. The post (X, and any other social account)
```
<Kind>: <what you can do now, one sentence>
<one or two sentences: how it works, the catch, or what it was tested on>
<link>
```
- `<Kind>` is `New`, `Better` or `Fixed`.
- 280 characters maximum including the link (X counts any link as 23).
- One link: the release if it has shipped, otherwise the PR.
- One visual when the change is visible: a screenshot from the app, a GIF, or a
short clip from the headset. Alt text describes what it shows.
- No hashtags, except `#SteamFrame` on releases and on posts about something
new, because people search for it.
### 2. The release-note line
One bullet under **New in x.y.z**, same as the current release notes: the
first half of the post's first sentence, no kind label, no link.
### 3. Release post
```
Frame Control <version>: <the headline change>
<one sentence on the headline change>. Also: <two or three short items>.
Windows, macOS and Linux: <release link>
#SteamFrame
```
The release title on GitHub uses the same `Frame Control <version>: <headline>`
line, as 0.3.0 and 0.3.1 already do.
### Roundups
Small fixes that don't earn their own post wait for a roundup, posted with the
next release or when three or more have piled up:
```
Fixed in Frame Control this week:
- <fix>
- <fix>
- <fix>
<link>
```
## Examples from what has already merged
**#11, older APK versions**
```
New: when an Android app is too new for the Frame, Frame Control now offers
older versions that will install.
It checks F-Droid, its archive and IzzyOnDroid, and verifies each download
before it goes on the headset.
https://github.com/saphid/steam-frame/pull/11
```
**#8, Mac mirror fixes**
```
Fixed: mirroring your Mac into the Steam Frame now fits the whole desktop in
the panel, asks for the right password, and shows the cursor.
Tested end to end on a real Frame from macOS 27.
https://github.com/saphid/steam-frame/pull/8
```
**v0.3.1**
```
Frame Control 0.3.1: install APKs without the Android SDK
Frame Control now reads APK files itself, so there's nothing extra to install.
Also: Linux and Windows game sideloading, and one-click install links.
Windows, macOS and Linux: https://github.com/saphid/steam-frame/releases/tag/v0.3.1
#SteamFrame
```
## Posting
Nothing is posted without a person approving it. The flow is:
1. The PR carries its `## Announcement` section.
2. On merge, the post is drafted from that section (manually for now).
3. Alex approves or edits it, then it's posted from the project account.
4. Replies and questions that turn out to be bugs become GitHub issues labelled
`feedback`, same as the website form.

# Computer use through Frame Control MCP
The MCP transport can carry semantic actions or visual computer-use actions.
The limits are the Frame's underlying interfaces, permissions and whether an
action can be targeted and verified. A stereoscopic headset screenshot alone
is not a reliable coordinate system for clicking a particular app window.
## What exists, and the right route
| Surface | Evidence and route | Remaining work or boundary |
|---|---|---|
| Frame management | **Verified:** existing SSH/HTTP operations for status, capture and file transfer work through MCP. Typed install/launch/power tools wrap the existing API. | Extend typed operations before adding generic mouse automation. Preserve explicit approval for consequential changes. |
| App/window observation | **Verified 2026-09-29:** `computer_state` reads gamescope X11 window/app/process triples, focused app and the installed AT-SPI library. | Bounded to 96 accessible nodes and six levels. Trees may be truncated, stale, hidden or incomplete. Snapshot paths and XIDs are observations, never durable action permissions. |
| Chromium page content | **Verified previously:** the assistant rendered and could be exercised through CDP in an isolated Frame Chromium profile. | A shipped click/type surface needs exact owned browser/target binding, fresh element references, lifecycle cleanup, consent and post-action readback. Do not expose unrestricted JavaScript or attach to arbitrary existing profiles automatically. |
| Steam UI | **Verified 2026-09-29:** the AT-SPI service listed the Steam client's Chromium process and frame nodes, but child traversal was incomplete. Existing `frame_steam.py` uses Steam's loopback CDP endpoint for specific operations. | Prefer those narrow Steam interfaces. Presence of AT-SPI does not prove controls are actionable, and generic pointer injection is not proved for VR menus. |
| Other Linux apps | **Verified 2026-09-29:** Frame ships libX11, libXtst and libatspi; `/dev/uinput` is writable by the current user. | Library presence and access permissions do not prove that a game accepts input. Global virtual input can affect whichever app has focus. Do not ship a blind keyboard/mouse tool on this evidence alone. |
| Panel focus and layouts | **Documented in [#41](https://github.com/saphid/frame-control/pull/41):** `POST /api/panels` accepts `list`, `focus` and `open`. Focus was verified there. | Reuse that owned interface after integration. Its tested gamescope-owned overlay transform setters return `PermissionDenied`; no reliable saved spatial-layout interface was established. Do not duplicate its implementation here. |
| Shared keyboard/trackpad | **Documented in [#19](https://github.com/saphid/frame-control/pull/19):** `/api/input` supplies state/start and event submission, implemented with a bundled KDE Connect daemon. | This branch does not import, launch or depend on that daemon. The user's own-implementation rule remains authoritative. A first-party input implementation or permitted bundled-library route needs its own delivery evidence before MCP integration. |
| Physical/device boundaries | **Documented:** an asleep Frame may be off the network; power authorization can require the user's password; physical pairing and headset fit/comfort require the user. | MCP cannot bypass offline hardware, consent, compositor permissions or physical verification. Keep explicit human handoffs. |
## Reusing the existing computer-use work
**Documented:** the installed `cua-driver` skill has the right control pattern:
observe an exact window, use a semantic target if available, fall back to pixels
from that same snapshot, then read back the result. Its browser route requires
an exact process/window/target binding and session-scoped element references.
Those are useful design rules for Frame tools.
**Verified locally 2026-09-29:** `cua-driver describe get_window_state` describes
host-local process/window IDs and macOS AX inspection. It does not establish an
SSH Frame target. The installed skill's advertised Linux companion file is
missing. A native ARM64 Frame backend, its dependencies and remote transport
have not been verified. We therefore do not claim that the existing Mac driver
can control the Frame by passing it a Frame PID or screenshot, and we do not
make the feature depend on installing that application.
Frame Control's `computer_state` is our own Python implementation over installed
platform libraries. It sends the probe over SSH stdin, writes no helper to disk,
and exits after one observation. Missing displays/libraries return explicit
errors; a 15-second process deadline prevents a stalled accessibility call from
leaving a probe behind. Window names and accessibility text are untrusted app
content, never instructions to an agent.
**Recommended next implementation:** an isolated Chromium session with typed
snapshot/click/type/scroll tools and exact fresh target binding, then individually
verified native app actions. Use the headset capture to judge appearance, not to
invent a screen-to-window coordinate transform. Direct tool calls must retain
approval rules; a generic computer-use tool must not become a route around the
MCP approval panel, install confirmation or power confirmation.
## Isolated browser input proof
**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** a temporary
Frame Chromium profile loaded a local test page through an SSH reverse tunnel.
CDP `Input.insertText` entered the test string in its own input. A CDP
`Input.dispatchMouseEvent` press/release on its own button copied that string
to the page's result; DOM readback matched exactly. The browser profile,
loopback forwards and panel log were removed afterward. No user app was typed
into, no global settings were changed and no third-party helper app was used.
AT-SPI did **not** expose the test page's controls in that same probe, even with
Chromium's renderer-accessibility flag. It returned the partial Steam-client
tree instead. The reason remains **unverified**; this is an evidence gap, not
proof that Frame accessibility cannot work. For a first implementation,
Chromium's proven page-specific CDP route is stronger than assuming complete
AT-SPI coverage. This proof does not ship unrestricted click/type tools or
establish input delivery to SteamVR's menus.

# Mod feasibility test, 2026-09-28
**Verified observations**, with limits below. Device: `aarch64`, SteamOS
`VERSION_ID=0.4.1`, `BUILD_ID=20260925.6191901`; Proton version file:
`1788505046 proton-11.0-2c-arm64`; `vrcmd --stats`: SteamVR `2.18.1`.
Times below are the Frame's AEST clock.
## Inventory and allowed content
`ssh frame 'python3 - owned' < ui/frame_steam.py` returned 868 games before
the test. Beat Saber (620980) and Skyrim VR (611670) were absent. Half-Life 2:
VR Mod – Episode One (2177750) was installed. Hogwarts Legacy (990080),
Horizon Zero Dawn (1151640) and Horizon Forbidden West (2420110) were listed
but not installed. The full personal library is not committed.
**Documented, owner report after these tests:** Alex has Beat Saber on a
Quest 2, which is charging. That copy was not accessed or inspected during
this test. Its version, transfer path and Frame compatibility remain unknown;
Steam ownership is still not established.
Gravitas's public Steam metadata reported `is_free: true`, developer Galaxy
Shark Studios, Windows only. Frame Control's existing Steam helper requested
its install. Steam first returned free-license state 3, then config state 7,
then queued the download. The helper did not accept state 3; a later read
found state 7. The source of that transition was not observed. A later
`install 1067310` returned `state: installed`. No purchase occurred.
UEVR was downloaded from the author's [1.05 release](https://github.com/praydog/UEVR/releases/tag/1.05),
not a mirror. `UEVR.zip` was 7,399,455 bytes. Its SHA-256 matched the author's
`UEVR.zip.sha256` (a UTF-16 text file):
```text
af4f2f91306802d7ee4e8497d483a547ac8e9a3067dbafb81324100524215d3c
```
Microsoft's Windows x64 .NET runtime and Windows Desktop runtime 6.0.36 ZIPs
were downloaded using URLs in the official release metadata. Both SHA-512
hashes matched that metadata. They were extracted into a test-only user
directory, not installed globally. No other mod manager was used.
## Half-Life 2 VR: visible setup, not gameplay
Launched the already-installed Episode One using
`steam steam://rungameid/2177750`. The existing manifest recorded build
25413453 and a shared base depot from app 658920, build 25413418.
Selected fresh Steam / SteamVR log lines:
```text
22:07:50 proton waitforexitandrun .../Half-Life 2 VR/ep1vr.exe
22:08:03 SetApplicationPid: Setting app steam.app.2177750 PID to 27990
22:08:03 Successfully loaded binding file '.../hlvr/cfg/steamvr/bindings_frame.json' for app 'steam.app.2177750'.
```
The game's `episodicvr/console.log` reached `Creating VR hand HUD...`,
`Creating VR weapon HUD...` and `Calibrating VR base position`. It also
contained missing material/weapon warnings. SteamVR logged a missing
`frame_hmd` binding as well as the successful controller binding load;
controller input was not exercised.
`ui/frame_vrshot.py` produced a stereo capture showing the mod's
“First time setup” and “Dominant hand” dialog. This establishes visible
startup, not a played level or comfortable performance. The capture includes
room passthrough and is deliberately not published. The test's `hl2.exe`
process was terminated; the pre-existing game installation was preserved.
## Gravitas and UEVR: injection unverified
The game was launched through Steam. The injector was then started in the
same `steamapps/compatdata/1067310` prefix using the shipped
`SteamLinuxRuntime_4-arm64/_v2-entry-point` and Proton 11 ARM64. The first
attempt reported:
```text
Application: UEVRInjector.exe
Message: You must install .NET to run this application.
Architecture: x64
App host version: 6.0.35
.NET location: Not found
```
With `DOTNET_ROOT` and `DOTNET_ROOT_X64` pointing at the test-only Windows
runtime directory, Proton loaded `Microsoft.NETCore.App/6.0.36` and
`Microsoft.WindowsDesktop.App/6.0.36`. A 25-second launcher timeout was too
short to establish whether the UI worked. A longer attempt produced a
625×372 `UEVR` X11 window on display `:1`. This is window creation evidence,
not a successful injection. That launcher returned exit 0; this was not
treated as proof that a mod worked.
A combined launch set `PROTON_REMOTE_DEBUG_CMD` to `UEVRInjector.exe` and
ran Gravitas's `Drop.exe` in the same runtime/prefix. The process
`SkyArk/Binaries/Win64/Drop-Win64-Shipping.exe` and a 1600×900 window titled
`SkyArk (64-bit, PCD3D_SM5)` appeared. The launcher exited **1** before an
injection or stereo game scene could be verified. Output included:
```text
Proton: Error while copying to ".../windows/system32/amdxcffx64.dll": No such file or directory
Error [GENERAL | xrCreateInstance | OpenXR-Loader] : xrCreateInstance failed
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 10 (X_UnmapWindow)
X Error of failed request: XI_BadDevice (invalid Device parameter)
Minor opcode of failed request: 28 (X_GetDeviceButtonMapping)
```
These errors do **not** establish an ARM64/FEX incompatibility. Other work
was launching apps on the shared Frame. SteamVR's PIDs changed during the
experiment; `ps` recorded the replacement `vrserver` and `vrcompositor`
starting at **22:13:03**, corroborated by `steamvr.service` journal startup
lines. This test did not request a Steam/SteamVR restart. The combined
attempt ran at 22:14:17–22:14:27, after that restart. A stable, coordinated
session is needed to distinguish launcher/environment problems from game or
mod incompatibility.
## Cleanup and remaining checks
- No game executable or OpenVR DLL was replaced. No global runtime or power
setting was changed by this test. No R.E.A.L., OpenComposite or Beat Saber
payload was installed.
- Removed the test-only UEVR/.NET directory and downloaded ZIPs from the
Frame. Final process checks found no `UEVRInjector.exe`,
`Drop-Win64-Shipping.exe`, `ep1vr.exe` or `hl2.exe`. SteamVR was running.
- Gravitas and its Steam-created prefix remain installed for a repeat test;
the pre-existing HL2 VR install remains. Steam may retain normal shader
caches, logs and prefix temporary files.
- Still unverified: UEVR injection and removal, R.E.A.L. releases and
permissions, OpenComposite, Beat Saber playback on either build, and our
own manager's end-to-end install/uninstall. No installer UI is justified
by these results. See the [support table and next checks](../mods.md).

# PC VR streaming from Linux
**Recommendation, 2026-09-28:** test Valve's current SteamVR/Steam Link path
on a Linux gaming PC before building another streamer. Valve now documents
Linux streaming fixes and USB support. We have no Linux host attached, so
Linux-to-Frame VR streaming remains **unverified here**.
This is the feasibility and options report for
[#24](https://github.com/saphid/frame-control/issues/24), not a shipped streaming
feature. Frame Control's features must use our own implementation or standard
platform components. WiVRn and ALVR are research comparisons, not dependencies.
An optional install shortcut is the most we would offer for a third-party app.
Our own streamer requires Alex's choice before implementation.
## What was checked on the Frame
**Verified** on 2026-09-28: aarch64, SteamOS **0.4.1**, BUILD_ID
`20260925.6191901`, SteamVR **2.18.1**. Version and build are recorded separately;
earlier docs associate this build with other SteamOS version labels.
| Client | Installation | Runtime result |
|---|---|---|
| WiVRn **26.9**, upstream `WiVRn-release.apk` | API 29, arm64-v8a; installed in its own immersive Lepton instance | OpenXR instance creation fails: missing `XR_KHR_convert_timespec_time`. Both 1.1.58 and 1.0.58 attempts return `XR_ERROR_EXTENSION_NOT_PRESENT` |
| ALVR **20.14.1**, upstream `alvr_client_android.apk` | API 26, arm64-v8a; installed in its own immersive Lepton instance | Same missing extension. Client panics at `client_openxr/src/lib.rs:220` with `ERROR_EXTENSION_NOT_PRESENT` |
The [evidence excerpt](evidence/linux-vr/2026-09-28.txt) includes APK SHA-256s,
upstream release links, loader errors and cleanup results. These are failures
before an OpenXR session, not successful VR clients. WiVRn was launched twice;
ALVR's container remained up despite its client panic. Container liveness alone
does not establish VR compatibility.
Both APKs already declare `MAIN` and `LAUNCHER`. They were installed unmodified
using this branch's existing `python3 ui/frame_android.py install APK --vr`,
then launched through their Steam shortcuts. Logs came from the instance's
`podman exec … /system/bin/logcat`; the user journal also retained WiVRn's errors
after its container exited. No headset was worn and no host was connected.
All test app files, compatdata, shortcuts and containers were removed afterwards.
SteamVR's original process remained running. No global settings changed.
### Relation to the VR APK branch
**Documented from source:** [PR #20](https://github.com/saphid/frame-control/pull/20)
was read, not edited (branch inspected at
[`038dcd4`](https://github.com/saphid/frame-control/commit/038dcd48cd75336f6a86c63c7878bfc9c52deec9)).
Its compatibility layer handles OpenXR version negotiation, some controller
profiles and refresh-rate requests. It does **not** implement
`XR_KHR_convert_timespec_time`. Its launcher fix is unnecessary for these APKs.
This report has **no unmerged code dependency** on that PR, and neither APK was
tested with its layer injected.
**Documented from upstream source:** WiVRn requests the extension in
[`application.cpp`](https://github.com/WiVRn/WiVRn/blob/bbc6e4cc36c355fa6180980abd231673dc15115d/client/application.cpp#L1286)
and uses it to convert `CLOCK_MONOTONIC` into `XrTime` in
[`instance::now()`](https://github.com/WiVRn/WiVRn/blob/bbc6e4cc36c355fa6180980abd231673dc15115d/client/xr/instance.cpp#L335).
ALVR also [requests it unconditionally](https://github.com/alvr-org/ALVR/blob/a9f6542fa507a841f40ab4f3fcb531427cd02550/alvr/client_openxr/src/lib.rs#L188).
Simply deleting the extension request or returning made-up timestamps would
not prove correct tracking or timing. A real fix needs a valid clock mapping
and further runtime tests. No such patch was made.
### Native SteamOS aarch64 clients
**Verified:** the Frame has a native OpenXR runtime manifest at
`~/.config/openxr/1/active_runtime.json`, pointing to SteamVR's
`bin/linuxarm64/vrclient.so`.
**Documented:** WiVRn's [26.9 README](https://github.com/WiVRn/WiVRn/blob/bbc6e4cc36c355fa6180980abd231673dc15115d/README.md)
describes its Linux client as debugging-only, without audio or hardware decode.
ALVR 20.14.1's [non-Android decoder](https://github.com/alvr-org/ALVR/blob/a9f6542fa507a841f40ab4f3fcb531427cd02550/alvr/client_core/src/video_decoder/mod.rs)
returns no decoded frames. The inspected releases ship Android clients, not a
ready-to-run native Frame client.
**Inferred:** a native port is possible research, but neither release offers a
demonstrated native alternative to the blocked APKs. Native builds, native
extension enumeration, hardware decoding and audio were **not tested**. The
Android extension failure does not establish that the native runtime lacks it.
## (a) Valve's own path — recommended first
**Documented**, from Valve's release notes rather than launch-window reports:
- [SteamVR 2.17.8 beta](https://steamstore-a.akamaihd.net/news/externalpost/steam_community_announcements/1842212951314598)
says “Fix crash using Steam Link on Linux when games submit invalid textures”
and “Improve streaming recovery when using Steam Link on Linux.” It also
adds initial USB streaming, with Steam Client Beta required to use USB
without Wi-Fi.
- [SteamVR 2.17 release](https://steamstore-a.akamaihd.net/news/externalpost/steam_community_announcements/1843481262693486)
repeats Linux streaming fixes and initial USB support. USB is no longer
solely a claim about an old beta, but version/channel requirements still
need checking on the actual host.
- [SteamVR 2.18.1 beta](https://steamstore-a.akamaihd.net/news/externalpost/steam_community_announcements/1844751498219787)
adds USB-tethered **Quest** support with Steam Link Beta. That entry is not
proof of a Frame/Linux combination.
- The [Steam Link page](https://store.steampowered.com/app/353380/Steam_Link/)
lists Linux desktop clients, while its Quest VR requirements still say
Windows 10 or newer. Desktop Steam Link support is not equivalent to VR host
support, and the Quest requirements are not a Frame support matrix.
**Inferred:** Valve has a Linux VR streaming path worth testing. The old blanket
claim “Linux cannot stream VR” is no longer justified by the evidence. These
release notes do not establish which Linux GPU/driver/Frame combinations work.
USB changes the transport; it does not by itself prove host encoder support.
**Not verified:** Linux host discovery, pairing, wireless or USB streaming,
stereo rendering, controllers, haptics, audio, latency, or a game. Frame-only
inspection cannot establish any of these. Flat Remote Play and a desktop shown
on a panel are not substitutes for this test.
Next test, once a Linux gaming PC is available: record distro, GPU/driver,
Steam client channel/version and SteamVR version; use the Frame's built-in
Steam connection flow, first wirelessly and then over a data-capable USB cable.
Launch a free OpenXR sample or developer-consented VR game. Verify stereo,
head/controller tracking, haptics and audio while worn; retain both ends' logs
and measure latency and recovery after a link interruption. Restore any test
channel changes. Do not change the shared headset's channel just for this report.
If that works, Frame Control can provide our own host checks, setup guidance
and session controls around Valve's existing platform. First establish which
controls have a usable interface; no stable automated pairing API has been
verified. **Estimate (inferred):** 2–5 engineer-days for the hardware feasibility
pass; another 1–2 weeks for a small integration if those interfaces exist.
## (b) Our own streaming — proposal only
This is a new VR transport and device integration, not a desktop capture feature.
A plausible first target is **one Linux GPU family, one host, one Frame**, using
SteamVR on both ends. Our host driver would expose a remote HMD/controllers,
receive poses and inputs, and obtain stereo textures for hardware encoding.
Our Frame OpenXR app would decode, submit the correct eye views and render poses
at predicted display times, and return tracking/input. SteamVR/OpenXR, bundled
codec/transport libraries and platform GPU APIs fit the ownership rule; a
WiVRn/ALVR/Monado server dependency would not.
**Inferred design risks:** Linux SteamVR texture-sharing/driver interfaces and
Frame decode-to-GPU interoperability need a spike before committing to this
architecture. Sending an already-composited desktop mirror loses the stereo,
pose and timing information we need. Late reprojection, clock conversion,
backpressure, controller bindings, audio sync and reconnects are substantial
work. A runtime shim must not assume `XrTime` equals monotonic nanoseconds.
### Reuse from `mac-in-headset`
**Documented from our code**, read-only at
[`1b90c64`](https://github.com/saphid/frame-control/commit/1b90c64b73bace54c63a3aae154c5d29a9448d72):
- Reuse the ideas for low-latency encoding without B-frames, dropping work
before encoding, bounded queues, keyframe recovery, adaptive bitrate,
per-frame timing and authenticated session setup.
- Its VideoToolbox encoder and ScreenCaptureKit capture are macOS-specific.
Linux needs a new GPU encoder path (for example VA-API or NVENC via bundled
libraries) and VR texture capture, not a port of window capture.
- Its WebSocket over SSH is useful for a first controlled transport experiment
and control messages. Reliable TCP can stall behind lost packets; a VR media
path needs measured deadline behaviour, likely datagrams with loss recovery
using an ordinary bundled transport library. Do not invent cryptography.
- Its Chromium/WebCodecs panel viewer is not a VR client. That branch reports
software H.264 decoding and occasional long Wi-Fi stalls on the Frame.
Its desktop latency measurements are not motion-to-photon measurements or
evidence that a 90/120 Hz stereo stream will work.
**Size/effort estimate (inferred, one experienced full-time engineer, hardware
available):**
| Phase | Deliverable / stop condition | Effort |
|---|---|---|
| Feasibility | Linux driver texture access, Frame hardware decode into OpenXR, pose/clock loop; stop if any cannot meet frame deadlines | 2–4 weeks |
| First end-to-end prototype | One GPU/codec, stereo sample over a controlled LAN, head/controllers, logs and teardown | 4–8 additional weeks |
| Usable limited beta | Audio/haptics, pairing, recovery, bitrate/loss handling, installer, worn testing and latency work | 6–12 additional weeks |
| Wider support | Multiple GPU vendors/distros, USB and Wi-Fi variation, long-session stability | 2–4 additional months |
Planning range: **12–24 engineer-weeks for a limited beta**, roughly
**10–25k lines of our code plus tests/tooling**, excluding bundled libraries.
This is a low-confidence scope estimate, not a delivery promise; an unsupported
driver or decode interface could block it entirely. Foveated streaming,
eye tracking and parity with Valve are excluded. A Linux gaming PC and repeatable
worn-headset testing are prerequisites. **Do not build this until Alex chooses.**
## (c) Optional “install WiVRn” shortcut only
Allowed as a clearly optional convenience, never a prerequisite for a Frame
Control feature. **Documented:** WiVRn's server Flatpak ID is
`io.github.wivrn.wivrn`; its client/server versions must match, and its Flatpak
includes xrizer/OpenComposite. Those are properties of an independently
installed third-party stack, not components of our implementation.
**Recommendation:** defer the shortcut while the current client fails before
session creation. If offered later, label that compatibility result and let
the user choose the install; do not present “install” as “streaming works.”
**Estimate (inferred):** 1–2 engineer-days for an optional host-side shortcut
with package/version detection and honest status, excluding third-party fixes.
No shortcut, host install, pairing automation or streaming UI was built here.
Choose **(a)** for the next hardware test. Keep **(b)** as a separately approved
project if Valve's path fails or lacks a required capability. **(c)** does not
solve the verified client blocker and should not be the product's foundation.

# Flat-to-VR mods and Beat Saber songs
**Status: feasibility work, not an installer.** Frame Control does not yet
manage mods or Beat Saber songs. [Issue #26](https://github.com/saphid/frame-control/issues/26)
stays open: neither UEVR injection nor Beat Saber custom-song playback has
been verified on this Frame. Alex has an owned copy on a Quest 2; that copy
has not been inspected. There is no Mods button until the underlying
install, playback and removal have been checked.
The mod manager must be Frame Control's own implementation. Mods and songs
are permitted third-party content; BSManager, ModsBeforeFriday, MO2 and other
managers must not be dependencies. Steam, Proton and SteamVR remain platform
dependencies. No game purchases, entitlement bypasses, withdrawn builds or
unofficial mod mirrors are part of this work.
## Per-game support
Checked 2026-09-28 on SteamOS **0.4.1**, BUILD_ID **20260925.6191901**, aarch64,
with **Proton 11.0-2c ARM64** and SteamVR **2.18.1**. “Verified” describes only
the observation stated, not a promise that the game is playable. “Documented”
means an upstream source describes it; “inferred” means it still needs a test.
| Game / build | Mod or content | Evidence and support status | Next check |
|---|---|---|---|
| Half-Life 2: VR Mod – Episode One, Steam 2177750, build 25413453 | Official Steam community mod, shared base depot 658920 build 25413418 | **Verified: startup only.** Already installed; launched through Proton ARM64. The stereo headset capture showed its first-time setup, and SteamVR loaded `bindings_frame.json`. Gameplay, controller interaction, fresh installation and removal are unverified. | Complete first-time setup and play a level before offering a tested install shortcut. |
| Gravitas, Steam 1067310, Windows | UEVR 1.05 | **Verified: prerequisites and windows only.** Free Steam install completed. The game produced a `SkyArk (64-bit, PCD3D_SM5)` window. UEVR needed .NET; with official .NET 6.0.36 libraries it produced a `UEVR` window. A combined run exited 1 with X11 errors before injection was verified. **Inferred: compatibility remains unknown**, not proven broken. | Retry during a stable headset session; verify injection, stereo scene output, controls and removal. |
| Beat Saber, Steam 620980, Windows / Proton | Basic custom songs; later SongCore and version-matched mods | **Verified: absent from the 868-game library returned by this Frame.** Store metadata lists Windows, not Linux. **Documented:** the PC game reads basic maps from `Beat Saber_Data/CustomLevels` without a mod manager. Playback on Frame is unverified. | An already-owned, legitimately installed copy is required. Do not buy it as part of this task. |
| Beat Saber, claimed native ARM64 build | Custom songs / native mods | **Inferred: unverified.** The research mentions this build but supplies no verified official distributable or tested layout. CPU architecture alone does not identify Android versus Linux, the game version or the mod ABI. | Establish official provenance, ownership, binary type and version before touching files. Do not apply Quest patches to an unidentified build. |
| Beat Saber, Alex's Quest 2 copy | Custom songs / Android mods | **Documented: owner-reported copy on Quest 2**, currently charging. No APK, version or installed mods inspected; no Frame playback verified. This does not establish ownership of the Steam build. | When the Quest is available, inspect the owned copy's version and supported transfer path, then test Lepton/OpenXR compatibility without bypassing entitlement checks. |
| Hogwarts Legacy, Steam 990080 | R.E.A.L. | **Verified: listed in this Frame's owned library, not installed.** Official release access and redistribution permission were not established; the referenced author Patreon page returned HTTP 403. No archive downloaded or game tested. | Obtain a current free release from the author and confirm its terms before any test. A news report saying “free” is not a redistribution grant. |
| Horizon Zero Dawn, Steam 1151640; Horizon Forbidden West, Steam 2420110 | R.E.A.L. | **Verified: both listed as owned, neither installed.** Same source/permission blocker as above; runtime support is unverified. | Check each game's supported version against an accessible official release. |
| Half-Life 2 VR / other OpenVR games | OpenComposite, per-game replacement | **Documented:** forwards OpenVR calls to OpenXR. **Inferred: Frame compatibility unknown.** Not installed or tested. HL2 VR reached setup with the shipped OpenVR path already. | Test a specific game and replacement DLL only if needed; preserve its original DLL. Never switch the shared headset's runtime globally. |
| Doom / Quake / Half-Life Team Beef ports | Author's VR ports plus separately owned or free game data | **Inferred: untested.** Android ARM64 support does not establish OpenXR extension or controller compatibility on Lepton. | Choose an official release and legally usable data set, then test that exact port. |
| Skyrim VR, Steam 611670 | SKSEVR / HIGGS / PLANCK stack | **Verified: Skyrim VR is absent from this library.** Owning flat Skyrim or Special Edition is not the VR game's entitlement. Runtime and mod support are unverified. | An already-owned VR copy and version-matched official mod releases are required. |
The [test record](evidence/mods-2026-09-28.md) distinguishes process startup,
visible output and failures. It also records a SteamVR restart during the
shared session, which prevents attributing the failed UEVR attempt to FEX.
## Beat Saber: songs first
**Documented:** the [BSMG PC guide](https://bsmg.wiki/pc-modding.html)
describes extracting each map into its own directory below
`Beat Saber/Beat Saber_Data/CustomLevels`. Basic custom songs do not require
SongCore; maps that require mod features need their matching dependencies.
This is a candidate for our own file manager, not a verified Frame feature.
Alex's Quest 2 copy is a separate Android candidate. Its ownership does not
make the PC `CustomLevels` layout applicable. Until the actual build is
inspected, neither a direct song-copy recipe nor APK patching is justified.
Only maps whose music and chart are permitted for distribution may be used
as test fixtures or bundled content. A public download alone does not establish
those rights. Start with an original or explicitly licensed basic map.
**Documented:** [ModsBeforeFriday](https://github.com/Lauriethefish/ModsBeforeFriday)
targets Quest Beat Saber over WebUSB/ADB. It is not a generic native ARM64
modding protocol. [BSManager](https://github.com/Zagrios/bs-manager/releases/tag/v1.6.0)
publishes an aarch64 Flatpak, but its architecture says nothing about Beat
Saber or its plugins running on Frame. Neither app is an installation step
or dependency for Frame Control.
## Requirements for our manager
These are **planned**, not implemented or verified:
1. Resolve the selected Steam game's real library, installed build, executable
architecture and Proton prefix. Confirm ownership through Steam; a directory
or app manifest alone is not proof. Keep downloading, installed and playable
as separate states.
2. Download a pinned mod version from the author's official release. Record
the URL, version, license and digest. Verify the published digest when
available; an upstream SHA-256 detects corruption but is not a signature.
Do not treat “free to download” as permission to redistribute.
3. Stage and validate archives before writing into the game or prefix. Reject
path traversal, links escaping the destination, archive bombs and unexpected
executable content in song packs. Check song metadata and its referenced
files, not just the `.zip` suffix.
4. Refuse changes while the game is running. Back up originals and journal
every managed file and digest. Apply changes atomically where possible and
roll back partial failures. Keep runtime prerequisites scoped to this game.
5. Uninstall only files still matching our receipt; restore originals without
overwriting later user edits. Preserve saves, unrelated mods and songs.
Song removal must target one managed map, never the whole CustomLevels tree.
6. Expose one-click actions beside the game only after real-Frame install,
playback and uninstall pass. Test filesystem and download failure handling
with fake-Frame fixtures; those cannot prove FEX injection or VR rendering.

# Privacy and analytics
Frame Control sends anonymous analytics to [PostHog](https://posthog.com)
(US cloud) so the maintainer can see how many people use it, which features
matter and where installs fail. You choose how much in **Privacy & updates**,
the last panel on the page. `ui/frame_telemetry.py` is the whole
implementation.
## The three levels
| Level | Default | What it sends |
|---|---|---|
| Anonymous usage statistics | On, after a notice on first run | The events in the table below |
| Share compatibility results | Off | Your Android compatibility reports and tests |
| Send error details | Off | Scrubbed error messages and tracebacks |
Nothing is sent until the first-run notice has been shown. The notice's
**Share more to help fix problems** button turns on the second and third
levels together. Either can be turned off later. Turning a level off
deletes that level's events that haven't been sent yet.
**Show what's been sent** in the panel lists the last 50 events that left your
computer, exactly as they were sent.
## Anonymous
- Events carry a random id, made when Frame Control first runs and kept in
its data folder (`telemetry/settings.json`). It isn't derived from your
computer, account or network. To get a new one, delete that file.
- Events are sent without person profiles (`$process_person_profile: false`)
and without location lookup (`$geoip_disable: true`). Each carries a
placeholder address (`$ip: 0.0.0.0`), so PostHog stores that instead of
yours.
- Every event includes the app version, OS name (macOS, Windows or Linux),
CPU architecture and Python version.

`install_finished` never includes a file name, path or error message. An
error becomes one category from a fixed list (for example `apk_wrong_abi` or
`frame_unreachable`), plus Android's own `INSTALL_FAILED_…` code when there
is one. It names what was installed only when that's already public:
- F-Droid catalogue apps: `package`. Never the version, since a local build can reuse a
catalogue app's package name
- Flathub apps: `flatpak_id`
- Steam games: `steam_appid`
- A sideloaded title: only its runtime (Proton or Linux)
Any other APK is sent as `catalog: false`, with no name.
## Compatibility results (opt-in)
Each report becomes a `compat_report` event with the fields the Report dialog
shows: package, version, result or rating, your notes, how it was run, and the
SteamOS and Lepton builds. Before sending:
- the notes, app name and version are scrubbed like error messages (see
below)
- the APK's source is kept only if it's `F-Droid` or the public host name of
a download link (`https://example.com/…`). File names, user names,
passwords, ports, paths, IP addresses and local host names are dropped
When you turn this on, reports you made earlier on this computer are shared
too.
The maintainer's `python3 ui/frame_compat_db.py sync` copies these events
into the compatibility database, marked `via=community…`. It takes at most
30 per reporter per day.
## Error details (opt-in)
`$exception` events carry an error message, the Frame Control file, line and
function it came from, and the request that failed (for example
`POST /api/android install`). Before anything is sent, the message is
scrubbed:
- your home folder becomes `~`, and any user name becomes `<user>`
- IP and MAC addresses, email addresses, `.local`, `.lan` and Tailscale host
names, Steam ids, SSH and PEM keys, API tokens and long hex strings are
replaced
- URLs are cut down to their scheme and a public host name, or `<url>`. User
names, passwords, ports, paths and queries are dropped
- `token=`, `key=`, `password=` and similar values are replaced
The same error is sent at most once every 10 minutes.
## Report a problem
**Report a problem** is the warning-sign button in the header, also in the
Privacy panel and under **Help → Report a Problem…**. It sends the report
privately to Frame Control's PostHog project as a `problem_report` event, the
same way as the analytics above, so only the maintainer can read it and
nothing is published. It works whatever the analytics settings are, because
the person sends it deliberately. The report has the kind, title and text you
wrote, how to reach you if you gave it, a short reference shown after sending,
and the diagnostics below. It has its own random id, so it isn't linked to
your analytics events.
With **Include diagnostics** ticked (the default), the report adds:
- the app version and whether it's a built app
- the OS, its release and CPU, and the Python version
- the Frame's SteamOS build, if it has connected since the app started
- which analytics levels are on
**Also include recent activity and the server log** is off by default,
because those lines can name files and apps. When ticked, it adds the newest
Activity lines and server log lines, without the request lines.
Everything is scrubbed like error details and limited to what fits in the
report. Environment details are kept first, then the newest lines. **Show
exactly what's included** shows the snapshot that will be sent, and later
activity isn't added to it. If PostHog can't be reached, **Copy report** puts
the whole report on the clipboard.
The maintainer reads reports on the Frame Control dashboard in PostHog, or
with `python3 ui/frame_report.py inbox [days]`, which uses the same personal
API key as `frame_compat_db.py sync`.
## Turning it all off
Untick the boxes, or set `DO_NOT_TRACK=1` or `FRAME_CONTROL_TELEMETRY=0` in
the environment that starts Frame Control. A copy run from a source checkout
never sends anything unless `FRAME_CONTROL_TELEMETRY=1` is set.
## Update checks
The desktop app asks GitHub for the latest release shortly after starting,
then every 6 hours: the latest release's `update.json` on GitHub, or
`api.github.com/repos/saphid/frame-control/releases/latest` if that fails.
Those requests carry no id. To stop it, set
`FRAME_CONTROL_NO_UPDATE_CHECK=1`. See [releasing.md](releasing.md).

# Releasing and updates
Frame Control checks for updates itself. The desktop app offers a new version
only once it's GitHub's **latest release**, and drafts and pre-releases never
count. So a build reaches people only when you publish it, after testing it.
## Steps
1. Bump `version` in `app/package.json`, commit, and push a tag:
```sh
git tag v0.4.0 && git push origin v0.4.0
```
`.github/workflows/release.yml` builds macOS, Windows and Linux, and
attaches everything to a **draft** release for that tag. Nobody is
offered a draft.
2. Download the draft's installers and test them. An installed copy of the
previous version won't offer the draft, so install it directly.
3. Write the release notes on the draft. The update banner links to them.
4. Publish:
```sh
scripts/publish-release.sh v0.4.0
```
The script checks that all eight installers are attached, each with the
SHA-256 digest GitHub records. It attaches `update.json` (the version, the
notes and each installer's digest), then publishes the release and marks it
latest. From then on, running copies see the update. They check about 8
seconds after starting, then every 6 hours, and anyone can use **Check for
Updates…** (the app menu on macOS, the Help menu elsewhere).
To pull a bad release, mark the previous one as latest
(`gh release edit v0.3.9 --latest`) or turn the bad one back into a draft.
Copies that already updated stay on it. Nothing downgrades them.
## How a copy updates itself
`app/updater.js` reads `update.json` from
`github.com/saphid/frame-control/releases/latest/download/`. It falls back to the
REST API only when a release has no manifest, because the API allows just 60
unauthenticated requests an hour per IP address, shared by a whole household.
Then it downloads the installer for its platform and checks it
against the SHA-256 digest GitHub publishes for the asset. It refuses if the
digest is missing or doesn't match. Then:
| Installed from | Update |
|---|---|
| macOS `.dmg`, app in a writable folder such as Applications | The `.zip` is unpacked next to the app and its version checked. After the app quits, a small script swaps the new app in, putting the old one back if that fails, and reopens it. Updates don't get the download quarantine, so there's no `xattr` step. |
| Windows installer | The new `Setup` runs silently over the install (`/S --force-run`) and reopens the app. |
| Linux AppImage | The new AppImage replaces the old file and is started. |
| macOS app still on the disk image or translocated, Windows `.zip`, Linux `.deb` | The banner opens the release page instead. |
Version 0.3.1 and earlier have no updater, so people on them have to download
the new version once by hand.

## Input: type and point in the Frame from the Mac or iPhone
**Verified 2026-09-27** on the headset: `steamos` is in the `input` group and
`/dev/uinput` is `crw-rw-r-- root input`, so **our own code can create a
virtual keyboard and mouse without sudo**. The Frame has no `python-evdev`,
`ydotool`, `wtype` or KDE Connect; `kwin_wayland` and `plasmashell` run only
while the desktop panel is open in the headset.
**Built: Home → Keyboard and trackpad**, in every version of Frame Control
(Mac, Windows, Linux, iPhone and iPad), with nothing to install on the device
you're holding. On a phone the panel is a trackpad (drag to move, tap to click,
two fingers to scroll, two-finger tap to right-click) plus a text field that
types on the Frame. On a computer, clicking the pad passes your mouse and
keyboard through to the Frame until you press Esc (⌘ is sent as Ctrl on a Mac).
| Option | Mac | iPhone | Notes |
It goes through **KDE Connect**, the first-party route (KDE makes the Frame's
desktop): Frame Control's server runs [`ui/frame_input_agent.py`](../ui/frame_input_agent.py)
on the Frame, which talks KDE Connect's own LAN protocol to the Frame's
`kdeconnectd` as if it were a phone. KDE Connect does the typing and clicking.
**Verified 2026-09-28** (SteamOS 0.4.1, build 20260925.6191901):
- KDE Connect isn't installed on the Frame, so **Frame Control ships it**:
Valve's own build for the Frame (`kdeconnect` 24.02.2-1 from its `extra`
repository) plus the five libraries it links that the Frame lacks
(`kcontacts`, `kpeople`, `modemmanager-qt`, `pulseaudio-qt`, `libfakekey`),
pinned by SHA-256 in [`frame/kdeconnect/packages.json`](../frame/kdeconnect/packages.json).
The builds download them from the
[kdeconnect-frame-24.02.2-1 release](https://github.com/saphid/frame-control/releases/tag/kdeconnect-frame-24.02.2-1)
(`app/build/fetch-deps.js`, `frame/kdeconnect/fetch.py`). The address of
Valve's repository for the Frame isn't to be shared, and Valve's public
aarch64 preview repository has KDE Connect 25.08, built against newer KDE
libraries than the Frame has.
- On first use, the computer copies them to the Frame over the SSH connection
it already has. The iPhone app's bundle, already copied to the Frame, has
them too. The agent checks each SHA-256 and unpacks them into
`~/.local/share/frame-control/kdeconnect` (3.6 MB copied, 18 MB unpacked,
about 2 s). There's no internet download on the Frame, no root, and nothing
on the read-only system, so SteamOS updates leave it alone. A stamp there
(`root/.frame-control-packages`) records which build it is; a newer Frame
Control replaces it.
- `pacman -Sp kdeconnect …` also pulls in ModemManager, libqmi, libmbim,
libqrtr-glib and ppp (packaging dependencies). `kdeconnectd` and its plugins
don't link any of them (checked with `ldd` against the six packages alone),
so Frame Control leaves them out.
- Licences: the packages are GPL and LGPL; Frame Control stays MIT because it
only starts `kdeconnectd` and speaks its protocol. The notice, licence texts
and complete source are in [`frame/kdeconnect`](../frame/kdeconnect/NOTICE.md),
[`THIRD_PARTY_NOTICES.md`](../THIRD_PARTY_NOTICES.md) and the app's
**About and licences** (Tools).
- It pairs by itself: the agent asks to pair and accepts on KDE Connect's side
over D-Bus (`qdbus6 … acceptPairing`). It keeps its identity in
`…/kdeconnect/bridge`, so later connections are already paired. (A pair
request to a device that's already paired makes KDE Connect unpair it, so
the agent only asks when it isn't paired.)
- Protocol version 7: whoever opens the TCP connection sends its identity line
in plain text, then acts as the **TLS server** (KDE Connect's
`lanlinkprovider.cpp`). Remote input is `kdeconnect.mousepad.request` with
`dx`/`dy`, `singleclick`, `rightclick`, `singlehold`/`singlerelease`,
`scroll`, `key` (any text) or `specialKey` (1 Backspace … 14 Escape,
21–32 F1–F12) and modifier flags.
- **KDE Connect runs only while something uses the keyboard and trackpad.**
Each device gets its own KDE Connect identity (KDE Connect keeps one
connection per device, so a shared one would make a phone and a computer
knock each other off). The last one to disconnect stops KDE Connect, so it
isn't left running, or discoverable on your network, afterwards.
- KDE Connect 24.02 **hangs or crashes when asked to unpair a device that's
offline** (seen twice: once spinning at 100% CPU with D-Bus unresponsive,
once exiting). Frame Control never unpairs. If its copy stops answering, the
agent restarts it once (tested by freezing it with `kill -STOP`).
- Moves from the iPhone app (Simulator) and the Mac's server moved the Frame's
X pointer by exactly the amount sent, including with the bundled packages
copied over SSH (2026-09-28).
- gamescope runs **two Xwayland displays**. `:0` holds Steam's VR bar and menus
and ignores injected pointer motion; `:1` holds apps such as Chromium and
takes it. KDE Connect runs on `:1`, so it reaches apps, not Steam's own menus.
There's also a `gamescope-0-ei` (libei) socket.
- Typing through KDE Connect lands in a Chromium panel on `:1` (seen in the
panel's own capture, 2026-09-29). It **can't reach panels on `:0`** (Frame
Control's own panels, Steam's UI) and, since XTest positions are clamped to
`:1`'s 1280×720 root, can't reach beyond that in a bigger window. Control on
the live view (below) has neither limit.
- **Not yet tested:** whether it reaches the KDE desktop panel (Plasma is its
own session).
- **Known limit:** keys and clicks typed while the link is reconnecting wait
and are sent once it's back, but anything sent in the moment the Wi-Fi
drops, before SSH notices, can be lost. Confirming every event would add a
round trip to each pointer move.
## Live view and Control: watch a panel and tap on it
**Built: Home → Desktop / Headset view → Control.** The live view has two
sources:
- **Headset view**: what the lenses show (SteamVR's mirror, `/dev/video99`). It
moves with the wearer's head, so Control makes the view a trackpad: drag to
move the pointer, tap to click, press and hold to right-click, two fingers to
scroll. With a mouse, moving over the view moves the pointer.
- **Desktop**: the app panel in use in the headset, from its own window, so it
stays still however the wearer looks around. Control makes taps and clicks
land exactly where you put them. Dragging is a mouse drag, press and hold is a
right-click, two fingers scroll, and on a computer the mouse, wheel and
keyboard work directly on it (⌘ is sent as Ctrl on a Mac). A picker shows any
other panel, view only.
Below the view, a text field and key buttons type on the Frame from a phone.
How (**verified 2026-09-29**, SteamOS 0.4.1, build 20260925.6191901):
- **Input goes through gamescope's own injection.** gamescope serves an EIS
socket (`/run/user/1000/gamescope-0-ei`; Steam feeds Remote Play input through
it), and `libei` 1.4.1 is on the image. [`ui/frame_touch.py`](../ui/frame_touch.py)
talks to it with `ctypes`: nothing to install. gamescope offers one device,
"Gamescope Virtual Input", with relative and absolute pointer, buttons,
scroll and keyboard (Linux key codes; no text capability, so the text field
types printable ASCII on a US layout). Its absolute region is unbounded; the
pointer uses the focused panel's display coordinates, and gamescope fits each
window to its display, so a 1920×1080 window on the 1280×720 `:1` takes
positions at two thirds scale. Taps on a 1280×720 page landed on the exact
pixel.
- **It reaches the panel that has focus** (`GAMESCOPE_FOCUSED_WINDOW` on `:0`'s
root), on either X display. In the OpenVR backend focus moves only on SteamVR
overlay events (the controller's laser entering or clicking a panel), or to a
new panel when none holds it (read from gamescope's `OpenVRBackend.cpp`, seen
with `gamescopectl focus_info`, which writes to the journal). Neither
`GAMESCOPECTRL_BASELAYER_WINDOW`/`_APPID` nor X focus moves it, and no
gamescope command does. So Control follows the wearer: whatever they last
used is what your taps reach. A window without a Steam app id (`STEAM_GAME`)
gets a connector of its own and doesn't hold focus.
- **Keys in a burst can arrive out of order**, so the helper paces them (8 ms
apart).
- **Known limit:** if focus moves to another panel in the middle of a drag, the
release goes to the panel that has focus then. Whether gamescope hands it to
the window that got the press isn't known yet. When the session ends, the
helper lets go of every button and key it still holds.
- **The Desktop picture is the window's own pixels**: `ffmpeg -f x11grab
-window_id <window> -i :<display>` works on gamescope's redirected windows,
while grabbing the root gives black. It streams as H.264 like the headset view
(about 30 fps at 720p).
- Tested from the iPhone app (Simulator): a tap on the Desktop view focused a
text box in the panel and the text field typed into it; a trackpad move went
exactly (+40, +25).
Our own `uinput` keyboard and mouse would also work (`steamos` is in the
`input` group and `/dev/uinput` is group-writable, verified 2026-09-27), and
remains the fallback if the bundled KDE Connect ever stops working on a new SteamOS.
| Other option | Mac | iPhone | Why not |

On the Mac: a "control the Frame" mode that captures the keyboard and pointer (Esc to release). Uinput devices look like real hardware to the kernel, so libinput, KWin and gamescope should take them; [frame-voice](https://github.com/DeeJanuz/frame-voice) already types into a Frame through a uinput keyboard. **Untested**: which surfaces in VR (desktop panel, SteamVR dashboard, games, Android apps in Lepton) accept the pointer.

# VR APKs and Quest games in Lepton
What it takes to run an immersive (OpenXR) Android app, including Meta Quest
builds, on the Frame. Checked on SteamOS BUILD_ID 20260925.6191901, Lepton
v2.8.14 (rootfs v2.8.11), SteamVR 2.18.1, on 2026-09-28, unless marked
**inferred**.
## How a VR APK reaches SteamVR (verified)
- Lepton ships a standard Khronos system runtime manifest,
`/vendor/etc/openxr/1/active_runtime.json`, pointing at SteamVR's Android
client, `/data/steamvr/runtime/bin/androidarm64/vrclient.so`. That is the
host's `/opt/steamvr/bin/androidarm64/`, bind-mounted in.
- An APK's own Khronos-style `libopenxr_loader.so` tries the runtime brokers
(`org.khronos.openxr.runtime_broker`, `…system_runtime_broker`), finds
neither, then falls back to that manifest. Nothing in the APK has to change
for discovery.
- Install the APK without the flatscreen marker
(`python3 ui/frame_android.py install app.apk --vr`). The marker only
controls Lepton's 2D Android surface; the app itself has to start an
OpenXR session.
- Lepton also loads Valve's `XR_APILAYER_VALVE_fdm_injection` layer from
`/vendor/etc/openxr/1/api_layers/implicit.d/`. Only layers in Valve's own
directories are picked up (`liblepton/vulkan_layers.sh`), so a third-party
layer has to ship inside the APK.
**Open Brush 2.32.29, the Quest APK from its GitHub release (Unity OpenXR,
Vulkan), works unmodified.** Its manifest already has `LAUNCHER` next to
`com.oculus.intent.category.VR`. Unity asked for OpenXR 1.1, got
`XR_ERROR_API_VERSION_UNSUPPORTED`, retried with 1.0 and succeeded. SteamVR
took it as the scene app, created Touch, simple-controller and Frame-controller
bindings, and the session reached `XR_SESSION_STATE_FOCUSED`. A headset capture
(`ui/frame_vrshot.py`, after waking the compositor and closing the dashboard)
showed a dark sky over a mountain horizon; nobody wore the headset to confirm
it was Open Brush's scene or to try drawing.
**Khronos `hello_xr` (Vulkan, 1.1.63 release APK) works unmodified:**
`Instance RuntimeName=SteamVR/OpenXR RuntimeVersion=2.18.1`, 1728×1728
swapchains per eye, session `IDLE → READY → SYNCHRONIZED` (the headset was
not being worn, so it did not reach `FOCUSED`).
## What SteamVR's Android runtime supports (verified, from `vrclient.so`)
- **OpenXR 1.0 only.** An app requesting `XR_API_VERSION_1_0` works; one
requesting 1.1 (`XR_CURRENT_API_VERSION` in a 1.1 SDK) gets
`XR_ERROR_API_VERSION_UNSUPPORTED` from the runtime.

## What stops a Quest APK (verified with Wolvic 1.9, `oculusvr` build)
1. **Lepton won't start it.** Lepton's `apk-info-extractor` only accepts an
activity whose intent filter has `android.intent.action.MAIN` and
`android.intent.category.LAUNCHER`. Quest apps use
`com.oculus.intent.category.VR` instead, so Lepton logs `APP_ACTIVITY is
empty` and exits. There is no override. **Fix:** add the `LAUNCHER`
category to that intent filter and re-sign. After that, Wolvic started.
2. **OpenXR 1.1.** Wolvic's Quest build then requested OpenXR 1.1 and aborted
on `XR_ERROR_API_VERSION_UNSUPPORTED`. Unity's OpenXR plugin retries with
1.0 (Open Brush, above), so this mostly bites native and non-Unity apps. **Fix (inferred):** an API layer
inside the APK that asks the runtime for 1.0 and maps the 1.1 core
functions to the extensions the runtime does have (`XR_KHR_locate_spaces`,
`XR_EXT_local_floor`, `XR_EXT_uuid`, `XR_EXT_palm_pose`).
3. **Lepton's missing clipboard service** still applies to VR apps. The Godot
XR Tools demo's Quest build (itch.io) dies in `Godot.<init>` casting the
null clipboard service to `ClipboardManager`, before any OpenXR call. See
the clipboard table in [apks.md](apks.md).
4. **Not yet reached:** required Meta-only extensions (each app differs),
swapchain formats (the Lynx Wolvic build needed `GL_SRGB8_ALPHA8`), and
Meta platform services.
The loader was never the problem: Wolvic's Quest `libopenxr_loader.so` is a
Khronos-style loader and found SteamVR through `/vendor`.
## Out of scope
- **Meta entitlement.** Apps that call the Oculus Platform SDK
(`libovrplatformloader.so`) to check the Quest store licence need Meta's
services. Frame Control won't work around that.
- **VrApi-era apps** (`libvrapi.so`, before OpenXR) need an API translator,
not a patch.
## Frame Control does this for you
APK uploads and `python3 ui/frame_android.py install app.apk` detect VR
manifest categories, Samsung's `vr_only` flag and the arm64 OpenXR loader.
VR apps default to immersive mode without the flatscreen marker. The upload
selector or CLI `--flat` / `--vr` overrides that choice. Compatibility notes
identify legacy VrApi, Meta platform SDK and OpenXR libraries.
Lepton only starts an `<activity>` whose MAIN intent filter has LAUNCHER; it
ignores `<activity-alias>`, which is where Godot 4 exports put LAUNCHER. When no
real activity qualifies, Frame Control adds LAUNCHER to the VR activity's MAIN
filter, or to the activity the launcher alias targets, then repacks and v2-signs
the APK locally before copying it; `meta.json` records
`"patched": ["launcher"]`. Unchanged ZIP members retain their compressed
bytes; stored libraries are aligned to 16 KiB. The RSA signing identity lives
in Frame Control's per-user app-data directory as `apk-signing-key.json`
(mode 0600). Keep this key to preserve the signer on subsequent patched
updates. A re-signed APK cannot update an installation signed by its original
publisher; Android also treats it as a different signer for signature checks.
VR apps with an arm64 OpenXR loader also get the OpenXR compatibility layer
([frame/openxr-compat](../frame/openxr-compat/README.md)): an implicit API
layer in the APK's `assets/openxr/1/api_layers/implicit.d/`, which the app's
own loader picks up next to Valve's layer. It asks SteamVR for OpenXR 1.0 when
the app wants 1.1 and enables the extensions that became 1.1 core; maps
`xrLocateSpaces` to `xrLocateSpacesKHR` and `grip_surface` to `palm_ext`; drops
1.1 controller profiles SteamVR doesn't know; stubs
`XR_KHR_android_thread_settings` and `XR_OCULUS_android_session_state_enable`;
and keeps the current refresh rate when SteamVR refuses a requested one.
`meta.json` records `"patched": ["openxr-compat"]`. Skip it with
`install … --no-xr-compat`. Its decisions go to logcat under `FrameXrCompat`.
Verified on the headset (2026-09-28):
- **Wolvic 1.9, Quest build**, installed as downloaded: Frame Control added
`LAUNCHER` and the layer. The layer turned OpenXR 1.1.48 into 1.0.63, the
instance and session were created, and a 144 Hz refresh request that SteamVR
refused was kept at the current rate. The session reached `SYNCHRONIZED`;
then Wolvic's Gecko engine crashed (null SIGSEGV on its Gecko thread, the
same crash its Lynx build has), which is Wolvic's, not OpenXR's.
- **Open Brush, Quest build**, with the layer: 1.1.54 → 1.0.63, the thread
settings stub in use, `bytedance/pico4_controller` bindings dropped, and the
session reached `FOCUSED`, the same as without the layer.
Inspect or prepare an APK without contacting the headset:
```sh
python3 ui/frame_android.py info app.apk
python3 ui/frame_android.py patch app.apk patched.apk
python3 ui/frame_android.py patch app.apk patched.apk --add assets/openxr/1/api_layers/implicit.d/X.json=X.json --add lib/arm64-v8a/libX.so=libX.so
```
The patch fixes Lepton's launch-category requirement. It does not supply an
OpenXR 1.1 translation layer, Meta services or a VrApi implementation.

# Watching VR video (180°/360°) on the Frame
# Movies, stereo photos and splats
The confidence labels are the same as in [ssh.md](ssh.md). Everything here
was checked on SteamOS 0.3.0, build 20260922.6101926.
Frame Control has its own Frame-side OpenVR player. It uses SteamOS's ffmpeg
and V4L2 hardware decoder, Python and SteamVR. **No separate player or viewer
is required.** Chromium and immersive WebXR are not in this playback path.
## The short version
## Use it
1. Install **DeoVR Video Player** from Steam (free, app 837380) and start it once
in the headset. That creates its Proton prefix.
2. On the Mac: `scripts/push-vr-video.sh --launch ~/Movies/beach_180_LR.mp4`
3. In the headset, open DeoVR's local file browser → **Videos → VR** and
pick the file.
In **Tools → Media in the headset**, send a file, choose its layout and press
**Play**. **Theatre** gives it a larger screen and an 85% black surround.
**Stop** removes both. Refresh reads the library and the player's state.
The screen follows your head; it isn't a saved world-space panel.
## Why DeoVR
The Frame's Chromium can't play VR video in 3D. It has no immersive WebXR
([how-the-frame-works.md](how-the-frame-works.md)). DeoVR's Windows build
runs under Proton ARM64 + FEX as a real SteamVR app. **Verified 2026-09-25:**
it found the Steam Frame headset and controller over OpenVR, and decoded
7680×3840 and 8192×4096 H.265 VR180 side-by-side streams through AVPro's
hardware Media Foundation path, mapped onto a 180° dome or fisheye mesh.
Known quirks (verified):
- The first launch takes about 45 s while it compiles shaders.
- Grid thumbnails stay blank. Unity's own video player, which DeoVR uses for
previews, fails with `0xc00d36bb` under Proton. Full playback uses AVPro
and isn't affected.
- The in-app store and web content are separate from local files. You don't
need an account to play your own files.
## Getting files onto the headset
`scripts/push-vr-video.sh` copies files with `rsync --partial`, so an
interrupted upload resumes. They go to `~/Videos/VR` on the Frame (`/home`
has about 860 GB free). The script also links that folder into DeoVR's prefix
as `C:\users\steamuser\Videos\VR`. It's reachable at
`Z:\home\steamos\Videos\VR` as well. **Verified** that the upload and link
work. **Not yet checked** whether DeoVR's file browser lands there
(open question 21).
Speed: a test upload over Wi-Fi ran at about 3–5 MB/s (verified 2026-09-25,
one sample). At that rate an 8K file of several GB takes tens of minutes, so
start big uploads before you put the headset on.
## Naming files so they play correctly
DeoVR guesses the projection from the file name. Its binary contains the tags
`_180`, `_360`, `_fisheye`, `_fisheye190`, `_mkx200`, `_vrca220` and `_rf52`
(verified). For stereo layout, the common DeoVR convention is `_LR`/`_SBS`
(side by side) and `_TB` (top/bottom) (inferred). If a video looks wrong
(doubled, warped, or flat), change the projection and stereo mode in DeoVR's
player menu.
Examples: `trip_180_LR.mp4`, `concert_360_TB.mp4`, `hike_fisheye190_LR.mp4`.
Codecs: H.265 at 8K played (verified, streamed). Local H.264 and H.265
files haven't been played yet. The test clips below cover that.
## Test clips
The script doesn't include these. To check a setup, make two 20 s clips:
3840×1920, 180° side by side, with the left eye tinted red and the right eye
cyan. In the headset each eye should see only its own colour. A single mixed
colour means the stereo split is wrong.
The command-line route uses the same player:
```sh
ffmpeg -f lavfi -i testsrc2=size=1920x1920:rate=30:duration=20 \
-filter_complex "[0:v]split[a][b];[a]colorchannelmixer=rr=1:gg=0.3:bb=0.3[l];[b]colorchannelmixer=rr=0.3:gg=1:bb=1[r];[l][r]hstack" \
-c:v libx264 -pix_fmt yuv420p -b:v 20M frame-test_180_LR_h264.mp4
scripts/push-vr-video.sh frame-test_180_LR_h264.mp4
scripts/push-vr-video.sh --launch --theatre ~/Movies/film_SBS.mp4
scripts/push-vr-video.sh --launch --layout ou ~/Pictures/stereo.png
scripts/push-vr-video.sh --launch capture.splat
scripts/push-vr-video.sh --list
scripts/push-vr-video.sh --stop
```
## Streaming from the Mac instead of copying (untested)
Uploads live in `~/Videos/FrameControl/<id>/` on the Frame. Each upload gets
its own directory, so sending another file with the same name doesn't replace
it. The UI's existing upload limit is 8 GiB. Transfers use the app's rsync/scp
path; resumable large uploads are not implemented here yet. Existing
`~/Videos/VR` files and Proton prefixes are left alone. The script no longer
launches DeoVR, links a Proton prefix, or accepts directories.
DeoVR has a DLNA browser (the binary contains `Searching for DLNA
devices...` and a UPnP ContentDirectory client). A DLNA server on the Mac
should therefore appear in DeoVR without copying anything, for example
`brew install rclone` then `rclone serve dlna ~/Movies/VR`. This is **inferred**, not
tried. 8K VR video needs roughly 50–100 Mbit/s sustained, and the Wi-Fi
sample above (about 30–40 Mbit/s) suggests copying first is the safer default.
| Media | Supported preview |
|---|---|
| Movies | H.264 / H.265, mono or left-first SBS / top-first OU; audio through the Frame's PulseAudio-compatible server |
| Stereo photos | PNG / JPEG containing both eyes, SBS or OU |
| Gaussian splats | Common 32-byte `.splat` records, 1–20,000 Gaussians; a stationary stereo preview |
Auto layout reads delimited filename tags: `_SBS`, `_HSBS`, `_LR`, `_OU`,
`_TB`, `_HOU`, `_HTB`, `_FSBS`, `_FOU`, `_FTB`. SBS/OU without `F` means
half-resolution packing. Full packing preserves each eye's original aspect.
It also accepts FFmpeg's `stereo_mode` metadata (`left_right`, `top_bottom`,
`mono`); left/right and top/bottom metadata are treated as full packing.
Choose an explicit layout if that assumption doesn't match the file.
Unknown or conflicting tags ask for a choice, rather than silently flattening
stereo. The explicit selector always wins. Layout is not guessed from resolution.
## What was verified
**Verified remotely, 2026-09-28:** SteamOS 0.4.1, BUILD_ID
`20260925.6191901`, SteamVR 2.18.1. Nobody wore the headset for these checks.
All test media were generated by us. No paid content or DRM was involved.
- Stock `ffmpeg` `h264_v4l2m2m` decoded 150 frames of our 1920×1080 H.264
test in 0.128 s (decode only); converting all frames to RGBA took 0.242 s.
- Our ffmpeg → Python → OpenVR path submitted all 150 frames and exited 0.
The 1280×720 prototype took 4.775 s; the full 1920×1080 player took
4.618 s. These are wall times, not in-headset frame-rate measurements.
Finishing a 5 s clip early showed those probes weren't paced, so the final
player paces output at 30 fps: all 150 frames then completed in **5.025 s**.
- The H.265 hardware decoder also completed the generated 1080p clip
(60 frames, exit 0); this is a short compatibility check, not a 4K/8K benchmark.
- Our actual player, launched through Frame Control's media API, displayed
SBS and OU photos with red only in the left-eye capture and cyan only in
the right. OpenVR's `SideBySide_Parallel` flag separates the eyes; we
rearrange OU rows ourselves.
- A generated 48-Gaussian `.splat` rendered in our own CPU renderer and appeared
in both eyes with separate perspective projections.
- Theatre's owned dark surround and screen appeared in captures. Steam's
dashboard remained available over them. Stop removed the owned overlays
and ended the dedicated user service. No global SteamVR setting was changed.
- A generated H.264/AAC clip reached the Pulse audio output and completed
all 100 video frames with exit 0. This proves the output path, not audible
quality or lip sync.
![Frame Control SBS eye-isolation proof: red left, cyan right](img/media-sbs-proof.png)
![Our Gaussian-splat stereo preview on the Frame](img/media-splat-proof.png)
**Verified failed route:** GStreamer 1.24.2's `playbin` selected
`v4l2h264dec`, delivered the first RGBA sample and then segfaulted (exit 139)
in the basic appsink probe and the OpenVR probe. We do not ship that route.
The ffmpeg path above completed instead.
## Limits and blockers
- **Not verified:** worn-headset comfort, sound quality/lip sync, long movies,
4K/8K decode, HDR, controller interaction or behaviour on other OS builds.
Output is bounded to 1920×1080 packed pixels before OU rearrangement.
- **Not implemented:** pause, seeking, subtitles, playlists, right-eye-first
layouts, non-square pixel correction, VR180/360 projection and fisheye.
This preview is a flat stereo screen, not a dome player.
- **Native spatial-photo blocker:** HEIC/HEIF/AVIF/MPO stereo-container
extraction isn't implemented in our viewer. We reject these rather than
displaying one image and calling it spatial. Export both eyes to PNG/JPEG
first. This is a current implementation gap, not a claim that the Frame
cannot support these containers.
- **Large/immersive splat blocker:** the owned CPU rasterizer projects 3D
covariance into each eye and alpha-composites Gaussians, but renders a
fixed view at 320×240 per eye. It caps each Gaussian footprint at 32 pixels
and normalizes the scene to a two-metre box. Large scenes, PLY/SPZ, live
head-position parallax and navigation need a GPU scene renderer; this
version rejects files above 20,000 records. It is a stereo preview, not
an immersive walk-through.
- A single player can run at a time. It stops at EOF, on **Stop**, or after
four hours in any case, so longer movies are cut off. Still images remain
until Stop or that timeout. There is no delete action yet: remove old
uploads from `~/Videos/FrameControl/` over SSH. The log is
`~/.local/share/frame-control/media/player.log` on the Frame.
- **Panel/stream theatre remains outside this media slice:** SteamVR's
`vrcmd --dock-overlay` accepts `theater`, but docking an existing panel
and its dimming behaviour were not verified here. The shared headset had
workspace and stream tests active. We did not reposition their panels.
Integration with [#22](https://github.com/saphid/frame-control/issues/22)
and [#31](https://github.com/saphid/frame-control/issues/31) can use the
owned rendering hook below; no second stream/window manager is introduced.
## Integration hook
`POST /api/upload` with `X-Mode: media` and `X-Filename` sends a file and
returns its `id`. `POST /api/media` accepts:
```json
{"action":"play","id":"<32 hex characters>/film_SBS.mp4","layout":"auto","theatre":true}
```
Other actions are `list`, `status`, `stop`. These use the normal `X-Frame-UI`
guard. Play reports **starting**, not a claim that frames reached the headset;
read status for `playing`, `ended`, `stopped` or `error`.
The own-code files are copied to `~/.local/share/frame-control/media/` and
run in the `frame-control-media.service` systemd user unit. Stop affects only
that unit, including its decoder child.
For a Frame-side stream producer, `frame_media_player.Overlay` exposes
`create(key, width, distance, stereo=False, aspect=1, order=1)`,
`pixels(handle, rgba, width, height)` and `close()`. Use an owned unique key,
pass interleaved RGBA bytes (left/right halves for stereo) and always close in
`finally`. `create` uses a head-relative transform; it does not move another
app's panel. The player demonstrates a separate black surround overlay.
`frame_media.stereo_pixels` converts OU to SBS. This is the narrow rendering
hook for stream/workspace work; it doesn't capture or manage a Mac/PC stream.
## Optional separate app
You can independently install **DeoVR Video Player** (free Steam app 837380)
if you prefer its VR180/360 features. Earlier tests on SteamOS 0.3.0,
build `20260922.6101926` (2026-09-25), verified its OpenVR initialization and
8K H.265 streamed VR180 decoding under Proton. Frame Control's media features
neither install nor launch it, and do not depend on it. Its behaviour and
file-naming conventions are not evidence about our player.

Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991 Copyright (C) 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the library GPL. It is numbered 2 because
it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Library General Public License, applies to some specially
designated Free Software Foundation software, and to any other libraries whose
authors decide to use it. You can use it for your libraries, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish), that you receive source code or can get it if you want it, that you
can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
a program with the library, you must provide complete object files to the
recipients so that they can relink them with the library, after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
Our method of protecting your rights has two steps: (1) copyright the library,
and (2) offer you this license which gives you legal permission to copy, distribute
and/or modify the library.
Also, for each distributor's protection, we want to make certain that everyone
understands that there is no warranty for this free library. If the library
is modified by someone else and passed on, we want its recipients to know
that what they have is not the original version, so that any problems introduced
by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We
wish to avoid the danger that companies distributing free software will individually
obtain patent licenses, thus in effect transforming the program into proprietary
software. To prevent this, we have made it clear that any patent must be licensed
for everyone's free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License, which was designed for utility programs. This license,
the GNU Library General Public License, applies to certain designated libraries.
This license is quite different from the ordinary one; be sure to read it
in full, and don't assume that anything in it is the same as in the ordinary
license.
The reason we have a separate public license for some libraries is that they
blur the distinction we usually make between modifying or adding to a program
and simply using it. Linking a program with a library, without changing the
library, is in some sense simply using the library, and is analogous to running
a utility program or application program. However, in a textual and legal
sense, the linked executable is a combined work, a derivative of the original
library, and the ordinary General Public License treats it as such.
Because of this blurred distinction, using the ordinary General Public License
for libraries did not effectively promote software sharing, because most developers
did not use the libraries. We concluded that weaker conditions might promote
sharing better.
However, unrestricted linking of non-free programs would deprive the users
of those programs of all benefit from the free status of the libraries themselves.
This Library General Public License is intended to permit developers of non-free
programs to use free libraries, while preserving your freedom as a user of
such programs to change the free libraries that are incorporated in them.
(We have not seen how to achieve this as regards changes in header files,
but we have achieved it as regards changes in the actual functions of the
Library.) The hope is that this will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, while the latter only works together with the library.
Note that it is possible for a library to be covered by the ordinary General
Public License rather than by this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a
notice placed by the copyright holder or other authorized party saying it
may be distributed under the terms of this Library General Public License
(also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also compile or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
d) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the operating
system on which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Library General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.
one line to give the library's name and an idea of what it does.
Copyright (C) year name of author
This library is free software; you can redistribute it and/or modify it under
the terms of the GNU Library General Public License as published by the Free
Software Foundation; either version 2 of the License, or (at your option)
any later version.
This library is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU Library General Public License for more
details.
You should have received a copy of the GNU Library General Public License
along with this library; if not, write to the Free Software Foundation, Inc.,
51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the library, if necessary. Here
is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in

APPENDIX: How to apply the Apache License to your work.
To apply the Apache License to your work, attach the following boilerplate
notice, with the fields enclosed by brackets "[]" replaced with your own identifying
information. (Don't include the brackets!) The text should be enclosed in
the appropriate comment syntax for the file format. We also recommend that
a file or class name and description of purpose be included on the same "printed

CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to
most of the Free Software Foundation's software and to any other program whose
authors commit to using it. (Some other Free Software Foundation software
is covered by the GNU Lesser General Public License instead.) You can apply
it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish), that you receive source code or can get it if you want it, that you
can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must give the recipients all the rights that you have. You
must make sure that they, too, receive or can get the source code. And you
must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2)
offer you this license which gives you legal permission to copy, distribute
and/or modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If
the software is modified by someone else and passed on, we want its recipients
to know that what they have is not the original, so that any problems introduced
by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We
wish to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification
follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms
of this General Public License. The "Program", below, refers to any such program
or work, and a "work based on the Program" means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or translated
into another language. (Hereinafter, translation is included without limitation
in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running the Program
is not restricted, and the output from the Program is covered only if its
contents constitute a work based on the Program (independent of having been
made by running the Program). Whether that is true depends on what the Program
does.
1. You may copy and distribute verbatim copies of the Program's source code
as you receive it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence
of any warranty; and give any other recipients of the Program a copy of this
License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it,
thus forming a work based on the Program, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) You must cause the modified files to carry prominent notices stating that
you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or
in part contains or is derived from the Program or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of this
License.
c) If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the most
ordinary way, to print or display an announcement including an appropriate
copyright notice and a notice that there is no warranty (or else, saying that
you provide a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print
such an announcement, your work based on the Program is not required to print
an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Program.
In addition, mere aggregation of another work not based on the Program with
the Program (or with a work based on the Program) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may copy and distribute the Program (or a work based on it, under Section
2) in object code or executable form under the terms of Sections 1 and 2 above
provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give
any third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the corresponding
source code, to be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial
distribution and only if you received the program in object code or executable
form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all
the source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
If distribution of executable or object code is made by offering access to
copy from a designated place, then offering equivalent access to copy the
source code from the same place counts as distribution of the source code,
even though third parties are not compelled to copy the source along with
the object code.
4. You may not copy, modify, sublicense, or distribute the Program except
as expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor
to copy, distribute or modify the Program subject to these terms and conditions.
You may not impose any further restrictions on the recipients' exercise of
the rights granted herein. You are not responsible for enforcing compliance
by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Program at all. For example, if a
patent license would not permit royalty-free redistribution of the Program
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and
the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose
any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse
of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and an idea of what it does.>
Copyright (C)< yyyy> <name of author>
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program; if not, write to the Free Software Foundation, Inc., 51 Franklin
Street, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when
it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software,
and you are welcome to redistribute it under certain conditions; type `show
c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may be
called something other than `show w' and `show c'; they could even be mouse-clicks
or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the program, if necessary. Here
is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'
(which makes passes at compilers) written by James Hacker.
<signature of Ty Coon >, 1 April 1989 Ty Coon, President of Vice This General
Public License does not permit incorporating your program into proprietary
programs. If your program is a subroutine library, you may consider it more
useful to permit linking proprietary applications with the library. If this
is what you want to do, use the GNU Lesser General Public License instead
of this License.

as expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor
to copy, distribute or modify the Program subject to these terms and conditions.
You may not impose any further restrictions on the recipients' exercise of
the rights granted herein. You are not responsible for enforcing compliance
by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Program at all. For example, if a
patent license would not permit royalty-free redistribution of the Program
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and
the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose
any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse
of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and an idea of what it does.>
Copyright (C) <yyyy> <name of author>
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program; if not, write to the Free Software Foundation, Inc., 51 Franklin
Street, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when
it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software,
and you are welcome to redistribute it under certain conditions; type `show
c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may be
called something other than `show w' and `show c'; they could even be mouse-clicks
or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the program, if necessary. Here
is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'
(which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General
Public License does not permit incorporating your program into proprietary
programs. If your program is a subroutine library, you may consider it more
useful to permit linking proprietary applications with the library. If this
is what you want to do, use the GNU Lesser General Public License instead
of this License.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for software and
other kinds of works.
The licenses for most software and other practical works are designed to take
away your freedom to share and change the works. By contrast, the GNU General
Public License is intended to guarantee your freedom to share and change all
versions of a program--to make sure it remains free software for all its users.
We, the Free Software Foundation, use the GNU General Public License for most
of our software; it applies also to any other work released this way by its
authors. You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for them if you wish), that
you receive source code or can get it if you want it, that you can change
the software or use pieces of it in new free programs, and that you know you
can do these things.
To protect your rights, we need to prevent others from denying you these rights
or asking you to surrender the rights. Therefore, you have certain responsibilities
if you distribute copies of the software, or if you modify it: responsibilities
to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must pass on to the recipients the same freedoms that you received.
You must make sure that they, too, receive or can get the source code. And
you must show them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1) assert
copyright on the software, and (2) offer you this License giving you legal
permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that
there is no warranty for this free software. For both users' and authors'
sake, the GPL requires that modified versions be marked as changed, so that
their problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified
versions of the software inside them, although the manufacturer can do so.
This is fundamentally incompatible with the aim of protecting users' freedom
to change the software. The systematic pattern of such abuse occurs in the
area of products for individuals to use, which is precisely where it is most
unacceptable. Therefore, we have designed this version of the GPL to prohibit
the practice for those products. If such problems arise substantially in other
domains, we stand ready to extend this provision to those domains in future
versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States
should not allow patents to restrict development and use of software on general-purpose
computers, but in those that do, we wish to avoid the special danger that
patents applied to a free program could make it effectively proprietary. To
prevent this, the GPL assures that patents cannot be used to render the program
non-free.
The precise terms and conditions for copying, distribution and modification
follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works,
such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License.
Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
or organizations.
To "modify" a work means to copy from or adapt all or part of the work in
a fashion requiring copyright permission, other than the making of an exact
copy. The resulting work is called a "modified version" of the earlier work
or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the
Program.
To "propagate" a work means to do anything with it that, without permission,
would make you directly or secondarily liable for infringement under applicable
copyright law, except executing it on a computer or modifying a private copy.
Propagation includes copying, distribution (with or without modification),
making available to the public, and in some countries other activities as
well.
To "convey" a work means any kind of propagation that enables other parties
to make or receive copies. Mere interaction with a user through a computer
network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the
extent that it includes a convenient and prominently visible feature that
(1) displays an appropriate copyright notice, and (2) tells the user that
there is no warranty for the work (except to the extent that warranties are
provided), that licensees may convey the work under this License, and how
to view a copy of this License. If the interface presents a list of user commands
or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making
modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard
defined by a recognized standards body, or, in the case of interfaces specified
for a particular programming language, one that is widely used among developers
working in that language.
The "System Libraries" of an executable work include anything, other than
the work as a whole, that (a) is included in the normal form of packaging
a Major Component, but which is not part of that Major Component, and (b)
serves only to enable use of the work with that Major Component, or to implement
a Standard Interface for which an implementation is available to the public
in source code form. A "Major Component", in this context, means a major essential
component (kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to produce
the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source
code needed to generate, install, and (for an executable work) run the object
code and to modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose
tools or generally available free programs which are used unmodified in performing
those activities but which are not part of the work. For example, Corresponding
Source includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically linked
subprograms that the work is specifically designed to require, such as by
intimate data communication or control flow between those subprograms and
other parts of the work.
The Corresponding Source need not include anything that users can regenerate
automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright
on the Program, and are irrevocable provided the stated conditions are met.
This License explicitly affirms your unlimited permission to run the unmodified
Program. The output from running a covered work is covered by this License
only if the output, given its content, constitutes a covered work. This License
acknowledges your rights of fair use or other equivalent, as provided by copyright
law.
You may make, run and propagate covered works that you do not convey, without
conditions so long as your license otherwise remains in force. You may convey
covered works to others for the sole purpose of having them make modifications
exclusively for you, or provide you with facilities for running those works,
provided that you comply with the terms of this License in conveying all material
for which you do not control copyright. Those thus making or running the covered
works for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of your copyrighted
material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions
stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure
under any applicable law fulfilling obligations under article 11 of the WIPO
copyright treaty adopted on 20 December 1996, or similar laws prohibiting
or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention
of technological measures to the extent such circumvention is effected by
exercising rights under this License with respect to the covered work, and
you disclaim any intention to limit operation or modification of the work
as a means of enforcing, against the work's users, your or third parties'
legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish
on each copy an appropriate copyright notice; keep intact all notices stating
that this License and any non-permissive terms added in accord with section
7 apply to the code; keep intact all notices of the absence of any warranty;
and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you
may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce
it from the Program, in the form of source code under the terms of section
4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and
giving a relevant date.
b) The work must carry prominent notices stating that it is released under
this License and any conditions added under section 7. This requirement modifies
the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone
who comes into possession of a copy. This License will therefore apply, along
with any applicable section 7 additional terms, to the whole of the work,
and all its parts, regardless of how they are packaged. This License gives
no permission to license the work in any other way, but it does not invalidate
such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate
Legal Notices; however, if the Program has interactive interfaces that do
not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works,
which are not by their nature extensions of the covered work, and which are
not combined with it such as to form a larger program, in or on a volume of
a storage or distribution medium, is called an "aggregate" if the compilation
and its resulting copyright are not used to limit the access or legal rights
of the compilation's users beyond what the individual works permit. Inclusion
of a covered work in an aggregate does not cause this License to apply to
the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections
4 and 5, provided that you also convey the machine-readable Corresponding
Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by the Corresponding Source fixed
on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by a written offer, valid for
at least three years and valid for as long as you offer spare parts or customer
support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical medium customarily
used for software interchange, for a price no more than your reasonable cost
of physically performing this conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is allowed only
occasionally and noncommercially, and only if you received the object code
with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis
or for a charge), and offer equivalent access to the Corresponding Source
in the same way through the same place at no further charge. You need not
require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the Corresponding
Source may be on a different server (operated by you or a third party) that
supports equivalent copying facilities, provided you maintain clear directions
next to the object code saying where to find the Corresponding Source. Regardless
of what server hosts the Corresponding Source, you remain obligated to ensure
that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform
other peers where the object code and Corresponding Source of the work are
being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from
the Corresponding Source as a System Library, need not be included in conveying
the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible
personal property which is normally used for personal, family, or household
purposes, or (2) anything designed or sold for incorporation into a dwelling.
In determining whether a product is a consumer product, doubtful cases shall
be resolved in favor of coverage. For a particular product received by a particular
user, "normally used" refers to a typical or common use of that class of product,
regardless of the status of the particular user or of the way in which the
particular user actually uses, or expects or is expected to use, the product.
A product is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent the
only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures,
authorization keys, or other information required to install and execute modified
versions of a covered work in that User Product from a modified version of
its Corresponding Source. The information must suffice to ensure that the
continued functioning of the modified object code is in no case prevented
or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically
for use in, a User Product, and the conveying occurs as part of a transaction
in which the right of possession and use of the User Product is transferred
to the recipient in perpetuity or for a fixed term (regardless of how the
transaction is characterized), the Corresponding Source conveyed under this
section must be accompanied by the Installation Information. But this requirement
does not apply if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has been installed
in ROM).
The requirement to provide Installation Information does not include a requirement
to continue to provide support service, warranty, or updates for a work that
has been modified or installed by the recipient, or for the User Product in
which it has been modified or installed. Access to a network may be denied
when the modification itself materially and adversely affects the operation
of the network or violates the rules and protocols for communication across
the network.
Corresponding Source conveyed, and Installation Information provided, in accord
with this section must be in a format that is publicly documented (and with
an implementation available to the public in source code form), and must require
no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License
by making exceptions from one or more of its conditions. Additional permissions
that are applicable to the entire Program shall be treated as though they
were included in this License, to the extent that they are valid under applicable
law. If additional permissions apply only to part of the Program, that part
may be used separately under those permissions, but the entire Program remains
governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any
additional permissions from that copy, or from any part of it. (Additional
permissions may be written to require their own removal in certain cases when
you modify the work.) You may place additional permissions on material, added
by you to a covered work, for which you have or can give appropriate copyright
permission.
Notwithstanding any other provision of this License, for material you add
to a covered work, you may (if authorized by the copyright holders of that
material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of
sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices displayed
by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring
that modified versions of such material be marked in reasonable ways as different
from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors
of the material; or
e) Declining to grant rights under trademark law for use of some trade names,
trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by
anyone who conveys the material (or modified versions of it) with contractual
assumptions of liability to the recipient, for any liability that these contractual
assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions"
within the meaning of section 10. If the Program as you received it, or any
part of it, contains a notice stating that it is governed by this License
along with a term that is a further restriction, you may remove that term.
If a license document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work material governed
by the terms of that license document, provided that the further restriction
does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place,
in the relevant source files, a statement of the additional terms that apply
to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form
of a separately written license, or stated as exceptions; the above requirements
apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided
under this License. Any attempt otherwise to propagate or modify it is void,
and will automatically terminate your rights under this License (including
any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from
a particular copyright holder is reinstated (a) provisionally, unless and
until the copyright holder explicitly and finally terminates your license,
and (b) permanently, if the copyright holder fails to notify you of the violation
by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently
if the copyright holder notifies you of the violation by some reasonable means,
this is the first time you have received notice of violation of this License
(for any work) from that copyright holder, and you cure the violation prior
to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses
of parties who have received copies or rights from you under this License.
If your rights have been terminated and not permanently reinstated, you do
not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy
of the Program. Ancillary propagation of a covered work occurring solely as
a consequence of using peer-to-peer transmission to receive a copy likewise
does not require acceptance. However, nothing other than this License grants
you permission to propagate or modify any covered work. These actions infringe
copyright if you do not accept this License. Therefore, by modifying or propagating
a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives
a license from the original licensors, to run, modify and propagate that work,
subject to this License. You are not responsible for enforcing compliance
by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization,
or substantially all assets of one, or subdividing an organization, or merging
organizations. If propagation of a covered work results from an entity transaction,
each party to that transaction who receives a copy of the work also receives
whatever licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the Corresponding
Source of the work from the predecessor in interest, if the predecessor has
it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights
granted or affirmed under this License. For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted under
this License, and you may not initiate litigation (including a cross-claim
or counterclaim in a lawsuit) alleging that any patent claim is infringed
by making, using, selling, offering for sale, or importing the Program or
any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License
of the Program or a work on which the Program is based. The work thus licensed
is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled
by the contributor, whether already acquired or hereafter acquired, that would
be infringed by some manner, permitted by this License, of making, using,
or selling its contributor version, but do not include claims that would be
infringed only as a consequence of further modification of the contributor
version. For purposes of this definition, "control" includes the right to
grant patent sublicenses in a manner consistent with the requirements of this
License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent
license under the contributor's essential patent claims, to make, use, sell,
offer for sale, import and otherwise run, modify and propagate the contents
of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement
or commitment, however denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to sue for patent infringement).
To "grant" such a patent license to a party means to make such an agreement
or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free
of charge and under the terms of this License, through a publicly available
network server or other readily accessible means, then you must either (1)
cause the Corresponding Source to be so available, or (2) arrange to deprive
yourself of the benefit of the patent license for this particular work, or
(3) arrange, in a manner consistent with the requirements of this License,
to extend the patent license to downstream recipients. "Knowingly relying"
means you have actual knowledge that, but for the patent license, your conveying
the covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that country
that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work, and grant
a patent license to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of the covered work,
then the patent license you grant is automatically extended to all recipients
of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope
of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
of one or more of the rights that are specifically granted under this License.
You may not convey a covered work if you are a party to an arrangement with
a third party that is in the business of distributing software, under which
you make payment to the third party based on the extent of your activity of
conveying the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by you
(or copies made from those copies), or (b) primarily for and in connection
with specific products or compilations that contain the covered work, unless
you entered into that arrangement, or that patent license was granted, prior
to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied
license or other defenses to infringement that may otherwise be available
to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise)
that contradict the conditions of this License, they do not excuse you from
the conditions of this License. If you cannot convey a covered work so as
to satisfy simultaneously your obligations under this License and any other
pertinent obligations, then as a consequence you may not convey it at all.
For example, if you agree to terms that obligate you to collect a royalty
for further conveying from those to whom you convey the Program, the only
way you could satisfy both those terms and this License would be to refrain
entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to
link or combine any covered work with a work licensed under version 3 of the
GNU Affero General Public License into a single combined work, and to convey
the resulting work. The terms of this License will continue to apply to the
part which is the covered work, but the special requirements of the GNU Affero
General Public License, section 13, concerning interaction through a network
will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the
GNU General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
that a certain numbered version of the GNU General Public License "or any
later version" applies to it, you have the option of following the terms and
conditions either of that numbered version or of any later version published
by the Free Software Foundation. If the Program does not specify a version
number of the GNU General Public License, you may choose any version ever
published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of
the GNU General Public License can be used, that proxy's public statement
of acceptance of a version permanently authorizes you to choose that version
for the Program.
Later license versions may give you additional or different permissions. However,
no additional obligations are imposed on any author or copyright holder as
a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot
be given local legal effect according to their terms, reviewing courts shall
apply local law that most closely approximates an absolute waiver of all civil
liability in connection with the Program, unless a warranty or assumption
of liability accompanies a copy of the Program in return for a fee. END OF
TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively state the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation, either version 3 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short notice like
this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it under certain
conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands might
be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary. For
more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General Public
License instead of this License. But first, please read <https://www.gnu.org/
licenses /why-not-lgpl.html>.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.
A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.
A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>

<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an “about box”.
You should also get your employer (if you work as a programmer) or school, if any, to sign a “copyright disclaimer” for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read <https://www.gnu.org/philosophy/why-not-lgpl.html>.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the
successor of the GNU Library Public License, version 2, hence the version
number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software Foundation
and other authors who decide to use it. You can use it too, but we suggest
you first think carefully about whether this license or the ordinary General
Public License is the better strategy to use in any particular case, based
on the explanations below.
When we speak of free software, we are referring to freedom of use, not price.
Our General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish); that you receive source code or can get it if you want it; that you
can change the software and use pieces of it in new free programs; and that
you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors
to deny you these rights or to ask you to surrender these rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
We protect your rights with a two-step method: (1) we copyright the library,
and (2) we offer you this license, which gives you legal permission to copy,
distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict the
users of a free program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this
license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public License,
applies to certain designated libraries, and is quite different from the ordinary
General Public License. We use this license for certain libraries in order
to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared
library, the combination of the two is legally speaking a combined work, a
derivative of the original library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for linking other
code with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over competing
non-free programs. These disadvantages are the reason we use the ordinary
General Public License for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the
widest possible use of a certain library, so that it becomes a de-facto standard.
To achieve this, non-free programs must be allowed to use the library. A more
frequent case is that a free library does the same job as widely used non-free
libraries. In this case, there is little to gain by limiting the free library
to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. For
example, permission to use the GNU C Library in non-free programs enables
many more people to use the whole GNU operating system, as well as its variant,
the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a modified
version of the Library.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, whereas the latter must be combined with the library in
order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General
Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (1) uses at run time a copy of the library
already present on the user's computer system, rather than copying library
functions into the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as the modified
version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
e) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the materials to be distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates the terms
and conditions of version 3 of the GNU General Public License, supplemented
by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser General
Public License, and the "GNU GPL" refers to version 3 of the GNU General Public
License.
"The Library" refers to a covered work governed by this License, other than
an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided by the
Library, but which is not otherwise based on the Library. Defining a subclass
of a class defined by the Library is deemed a mode of using an interface provided
by the Library.
A "Combined Work" is a work produced by combining or linking an Application
with the Library. The particular version of the Library with which the Combined
Work was made is also called the "Linked Version".
The "Minimal Corresponding Source" for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the
Combined Work that, considered in isolation, are based on the Application,
and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the object
code and/or source code for the Application, including any data and utility
programs needed for reproducing the Combined Work from the Application, but
excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License without
being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a facility
refers to a function or data to be supplied by an Application that uses the
facility (other than as an argument passed when the facility is invoked),
then you may convey a copy of the modified version:
a) under this License, provided that you make a good faith effort to ensure
that, in the event an Application does not supply the function or data, the
facility still operates, and performs whatever part of its purpose remains
meaningful, or
b) under the GNU GPL, with none of the additional permissions of this License
applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from a header
file that is part of the Library. You may convey such object code under terms
of your choice, provided that, if the incorporated material is not limited
to numerical parameters, data structure layouts and accessors, or small macros,
inline functions and templates (ten or fewer lines in length), you do both
of the following:
a) Give prominent notice with each copy of the object code that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that, taken together,
effectively do not restrict modification of the portions of the Library contained
in the Combined Work and reverse engineering for debugging such modifications,
if you also do each of the following:
a) Give prominent notice with each copy of the Combined Work that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during execution, include
the copyright notice for the Library among these notices, as well as a reference
directing the user to the copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this License,
and the Corresponding Application Code in a form suitable for, and under terms
that permit, the user to recombine or relink the Application with a modified
version of the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
1) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (a) uses at run time a copy of the Library
already present on the user's computer system, and (b) will operate properly
with a modified version of the Library that is interface-compatible with the
Linked Version.
e) Provide Installation Information, but only if you would otherwise be required
to provide such information under section 6 of the GNU GPL, and only to the
extent that such information is necessary to install and execute a modified
version of the Combined Work produced by recombining or relinking the Application
with a modified version of the Linked Version. (If you use option 4d0, the
Installation Information must accompany the Minimal Corresponding Source and
Corresponding Application Code. If you use option 4d1, you must provide the
Installation Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the Library side
by side in a single library together with other library facilities that are
not Applications and are not covered by this License, and convey such a combined
library under terms of your choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities, conveyed under the
terms of this License.
b) Give prominent notice with the combined library that part of it is a work
based on the Library, and explaining where to find the accompanying uncombined
form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions of the
GNU Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library as you
received it specifies that a certain numbered version of the GNU Lesser General
Public License "or any later version" applies to it, you have the option of
following the terms and conditions either of that published version or of
any later version published by the Free Software Foundation. If the Library
as you received it does not specify a version number of the GNU Lesser General
Public License, you may choose any version of the GNU Lesser General Public
License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide whether
future versions of the GNU Lesser General Public License shall apply, that
proxy's public statement of acceptance of any version is permanent authorization
for you to choose that version for the Library.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the
successor of the GNU Library Public License, version 2, hence the version
number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software Foundation
and other authors who decide to use it. You can use it too, but we suggest
you first think carefully about whether this license or the ordinary General
Public License is the better strategy to use in any particular case, based
on the explanations below.
When we speak of free software, we are referring to freedom of use, not price.
Our General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish); that you receive source code or can get it if you want it; that you
can change the software and use pieces of it in new free programs; and that
you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors
to deny you these rights or to ask you to surrender these rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
We protect your rights with a two-step method: (1) we copyright the library,
and (2) we offer you this license, which gives you legal permission to copy,
distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict the
users of a free program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this
license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public License,
applies to certain designated libraries, and is quite different from the ordinary
General Public License. We use this license for certain libraries in order
to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared
library, the combination of the two is legally speaking a combined work, a
derivative of the original library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for linking other
code with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over competing
non-free programs. These disadvantages are the reason we use the ordinary
General Public License for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the
widest possible use of a certain library, so that it becomes a de-facto standard.
To achieve this, non-free programs must be allowed to use the library. A more
frequent case is that a free library does the same job as widely used non-free
libraries. In this case, there is little to gain by limiting the free library
to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. For
example, permission to use the GNU C Library in non-free programs enables
many more people to use the whole GNU operating system, as well as its variant,
the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a modified
version of the Library.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, whereas the latter must be combined with the library in
order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General
Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (1) uses at run time a copy of the library
already present on the user's computer system, rather than copying library
functions into the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as the modified
version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
e) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the materials to be distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.
<one line to give the library's name and an idea of what it does.>
Copyright (C) <year> <name of author>

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991 Copyright (C) 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the library GPL. It is numbered 2 because
it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Library General Public License, applies to some specially
designated Free Software Foundation software, and to any other libraries whose
authors decide to use it. You can use it for your libraries, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish), that you receive source code or can get it if you want it, that you
can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
a program with the library, you must provide complete object files to the
recipients so that they can relink them with the library, after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
Our method of protecting your rights has two steps: (1) copyright the library,
and (2) offer you this license which gives you legal permission to copy, distribute
and/or modify the library.
Also, for each distributor's protection, we want to make certain that everyone
understands that there is no warranty for this free library. If the library
is modified by someone else and passed on, we want its recipients to know
that what they have is not the original version, so that any problems introduced
by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We
wish to avoid the danger that companies distributing free software will individually
obtain patent licenses, thus in effect transforming the program into proprietary
software. To prevent this, we have made it clear that any patent must be licensed
for everyone's free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License, which was designed for utility programs. This license,
the GNU Library General Public License, applies to certain designated libraries.
This license is quite different from the ordinary one; be sure to read it
in full, and don't assume that anything in it is the same as in the ordinary
license.
The reason we have a separate public license for some libraries is that they
blur the distinction we usually make between modifying or adding to a program
and simply using it. Linking a program with a library, without changing the
library, is in some sense simply using the library, and is analogous to running
a utility program or application program. However, in a textual and legal
sense, the linked executable is a combined work, a derivative of the original
library, and the ordinary General Public License treats it as such.
Because of this blurred distinction, using the ordinary General Public License
for libraries did not effectively promote software sharing, because most developers
did not use the libraries. We concluded that weaker conditions might promote
sharing better.
However, unrestricted linking of non-free programs would deprive the users
of those programs of all benefit from the free status of the libraries themselves.
This Library General Public License is intended to permit developers of non-free
programs to use free libraries, while preserving your freedom as a user of
such programs to change the free libraries that are incorporated in them.
(We have not seen how to achieve this as regards changes in header files,
but we have achieved it as regards changes in the actual functions of the
Library.) The hope is that this will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, while the latter only works together with the library.
Note that it is possible for a library to be covered by the ordinary General
Public License rather than by this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a
notice placed by the copyright holder or other authorized party saying it
may be distributed under the terms of this Library General Public License
(also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also compile or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
d) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the operating
system on which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Library General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.
one line to give the library's name and an idea of what it does.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to
most of the Free Software Foundation's software and to any other program whose
authors commit to using it. (Some other Free Software Foundation software
is covered by the GNU Lesser General Public License instead.) You can apply
it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish), that you receive source code or can get it if you want it, that you
can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must give the recipients all the rights that you have. You
must make sure that they, too, receive or can get the source code. And you
must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2)
offer you this license which gives you legal permission to copy, distribute
and/or modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If
the software is modified by someone else and passed on, we want its recipients
to know that what they have is not the original, so that any problems introduced
by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We
wish to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification
follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms
of this General Public License. The "Program", below, refers to any such program
or work, and a "work based on the Program" means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or translated
into another language. (Hereinafter, translation is included without limitation
in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running the Program
is not restricted, and the output from the Program is covered only if its
contents constitute a work based on the Program (independent of having been
made by running the Program). Whether that is true depends on what the Program
does.
1. You may copy and distribute verbatim copies of the Program's source code
as you receive it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence
of any warranty; and give any other recipients of the Program a copy of this
License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it,
thus forming a work based on the Program, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) You must cause the modified files to carry prominent notices stating that
you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or
in part contains or is derived from the Program or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of this
License.
c) If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the most
ordinary way, to print or display an announcement including an appropriate
copyright notice and a notice that there is no warranty (or else, saying that
you provide a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print
such an announcement, your work based on the Program is not required to print
an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Program.
In addition, mere aggregation of another work not based on the Program with
the Program (or with a work based on the Program) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may copy and distribute the Program (or a work based on it, under Section
2) in object code or executable form under the terms of Sections 1 and 2 above
provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give
any third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the corresponding
source code, to be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial
distribution and only if you received the program in object code or executable
form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all
the source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
If distribution of executable or object code is made by offering access to
copy from a designated place, then offering equivalent access to copy the
source code from the same place counts as distribution of the source code,
even though third parties are not compelled to copy the source along with
the object code.
4. You may not copy, modify, sublicense, or distribute the Program except
as expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor
to copy, distribute or modify the Program subject to these terms and conditions.
You may not impose any further restrictions on the recipients' exercise of
the rights granted herein. You are not responsible for enforcing compliance
by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Program at all. For example, if a
patent license would not permit royalty-free redistribution of the Program
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and
the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose
any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse
of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and an idea of what it does.>
Copyright (C)< yyyy> <name of author>
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program; if not, write to the Free Software Foundation, Inc., 51 Franklin
Street, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when
it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software,
and you are welcome to redistribute it under certain conditions; type `show
c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may be
called something other than `show w' and `show c'; they could even be mouse-clicks
or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the program, if necessary. Here
is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'
(which makes passes at compilers) written by James Hacker.
<signature of Ty Coon >, 1 April 1989 Ty Coon, President of Vice This General
Public License does not permit incorporating your program into proprietary
programs. If your program is a subroutine library, you may consider it more
useful to permit linking proprietary applications with the library. If this
is what you want to do, use the GNU Lesser General Public License instead
of this License.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for software and
other kinds of works.
The licenses for most software and other practical works are designed to take
away your freedom to share and change the works. By contrast, the GNU General
Public License is intended to guarantee your freedom to share and change all
versions of a program--to make sure it remains free software for all its users.
We, the Free Software Foundation, use the GNU General Public License for most
of our software; it applies also to any other work released this way by its
authors. You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for them if you wish), that
you receive source code or can get it if you want it, that you can change
the software or use pieces of it in new free programs, and that you know you
can do these things.
To protect your rights, we need to prevent others from denying you these rights
or asking you to surrender the rights. Therefore, you have certain responsibilities
if you distribute copies of the software, or if you modify it: responsibilities
to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must pass on to the recipients the same freedoms that you received.
You must make sure that they, too, receive or can get the source code. And
you must show them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1) assert
copyright on the software, and (2) offer you this License giving you legal
permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that
there is no warranty for this free software. For both users' and authors'
sake, the GPL requires that modified versions be marked as changed, so that
their problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified
versions of the software inside them, although the manufacturer can do so.
This is fundamentally incompatible with the aim of protecting users' freedom
to change the software. The systematic pattern of such abuse occurs in the
area of products for individuals to use, which is precisely where it is most
unacceptable. Therefore, we have designed this version of the GPL to prohibit
the practice for those products. If such problems arise substantially in other
domains, we stand ready to extend this provision to those domains in future
versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States
should not allow patents to restrict development and use of software on general-purpose
computers, but in those that do, we wish to avoid the special danger that
patents applied to a free program could make it effectively proprietary. To
prevent this, the GPL assures that patents cannot be used to render the program
non-free.
The precise terms and conditions for copying, distribution and modification
follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works,
such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License.
Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
or organizations.
To "modify" a work means to copy from or adapt all or part of the work in
a fashion requiring copyright permission, other than the making of an exact
copy. The resulting work is called a "modified version" of the earlier work
or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the
Program.
To "propagate" a work means to do anything with it that, without permission,
would make you directly or secondarily liable for infringement under applicable
copyright law, except executing it on a computer or modifying a private copy.
Propagation includes copying, distribution (with or without modification),
making available to the public, and in some countries other activities as
well.
To "convey" a work means any kind of propagation that enables other parties
to make or receive copies. Mere interaction with a user through a computer
network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the
extent that it includes a convenient and prominently visible feature that
(1) displays an appropriate copyright notice, and (2) tells the user that
there is no warranty for the work (except to the extent that warranties are
provided), that licensees may convey the work under this License, and how
to view a copy of this License. If the interface presents a list of user commands
or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making
modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard
defined by a recognized standards body, or, in the case of interfaces specified
for a particular programming language, one that is widely used among developers
working in that language.
The "System Libraries" of an executable work include anything, other than
the work as a whole, that (a) is included in the normal form of packaging
a Major Component, but which is not part of that Major Component, and (b)
serves only to enable use of the work with that Major Component, or to implement
a Standard Interface for which an implementation is available to the public
in source code form. A "Major Component", in this context, means a major essential
component (kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to produce
the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source
code needed to generate, install, and (for an executable work) run the object
code and to modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose
tools or generally available free programs which are used unmodified in performing
those activities but which are not part of the work. For example, Corresponding
Source includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically linked
subprograms that the work is specifically designed to require, such as by
intimate data communication or control flow between those subprograms and
other parts of the work.
The Corresponding Source need not include anything that users can regenerate
automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright
on the Program, and are irrevocable provided the stated conditions are met.
This License explicitly affirms your unlimited permission to run the unmodified
Program. The output from running a covered work is covered by this License
only if the output, given its content, constitutes a covered work. This License
acknowledges your rights of fair use or other equivalent, as provided by copyright
law.
You may make, run and propagate covered works that you do not convey, without
conditions so long as your license otherwise remains in force. You may convey
covered works to others for the sole purpose of having them make modifications
exclusively for you, or provide you with facilities for running those works,
provided that you comply with the terms of this License in conveying all material
for which you do not control copyright. Those thus making or running the covered
works for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of your copyrighted
material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions
stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure
under any applicable law fulfilling obligations under article 11 of the WIPO
copyright treaty adopted on 20 December 1996, or similar laws prohibiting
or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention
of technological measures to the extent such circumvention is effected by
exercising rights under this License with respect to the covered work, and
you disclaim any intention to limit operation or modification of the work
as a means of enforcing, against the work's users, your or third parties'
legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish
on each copy an appropriate copyright notice; keep intact all notices stating
that this License and any non-permissive terms added in accord with section
7 apply to the code; keep intact all notices of the absence of any warranty;
and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you
may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce
it from the Program, in the form of source code under the terms of section
4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and
giving a relevant date.
b) The work must carry prominent notices stating that it is released under
this License and any conditions added under section 7. This requirement modifies
the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone
who comes into possession of a copy. This License will therefore apply, along
with any applicable section 7 additional terms, to the whole of the work,
and all its parts, regardless of how they are packaged. This License gives
no permission to license the work in any other way, but it does not invalidate
such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate
Legal Notices; however, if the Program has interactive interfaces that do
not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works,
which are not by their nature extensions of the covered work, and which are
not combined with it such as to form a larger program, in or on a volume of
a storage or distribution medium, is called an "aggregate" if the compilation
and its resulting copyright are not used to limit the access or legal rights
of the compilation's users beyond what the individual works permit. Inclusion
of a covered work in an aggregate does not cause this License to apply to
the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections
4 and 5, provided that you also convey the machine-readable Corresponding
Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by the Corresponding Source fixed
on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by a written offer, valid for
at least three years and valid for as long as you offer spare parts or customer
support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical medium customarily
used for software interchange, for a price no more than your reasonable cost
of physically performing this conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is allowed only
occasionally and noncommercially, and only if you received the object code
with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis
or for a charge), and offer equivalent access to the Corresponding Source
in the same way through the same place at no further charge. You need not
require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the Corresponding
Source may be on a different server (operated by you or a third party) that
supports equivalent copying facilities, provided you maintain clear directions
next to the object code saying where to find the Corresponding Source. Regardless
of what server hosts the Corresponding Source, you remain obligated to ensure
that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform
other peers where the object code and Corresponding Source of the work are
being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from
the Corresponding Source as a System Library, need not be included in conveying
the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible
personal property which is normally used for personal, family, or household
purposes, or (2) anything designed or sold for incorporation into a dwelling.
In determining whether a product is a consumer product, doubtful cases shall
be resolved in favor of coverage. For a particular product received by a particular
user, "normally used" refers to a typical or common use of that class of product,
regardless of the status of the particular user or of the way in which the
particular user actually uses, or expects or is expected to use, the product.
A product is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent the
only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures,
authorization keys, or other information required to install and execute modified
versions of a covered work in that User Product from a modified version of
its Corresponding Source. The information must suffice to ensure that the
continued functioning of the modified object code is in no case prevented
or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically
for use in, a User Product, and the conveying occurs as part of a transaction
in which the right of possession and use of the User Product is transferred
to the recipient in perpetuity or for a fixed term (regardless of how the
transaction is characterized), the Corresponding Source conveyed under this
section must be accompanied by the Installation Information. But this requirement
does not apply if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has been installed
in ROM).
The requirement to provide Installation Information does not include a requirement
to continue to provide support service, warranty, or updates for a work that
has been modified or installed by the recipient, or for the User Product in
which it has been modified or installed. Access to a network may be denied
when the modification itself materially and adversely affects the operation
of the network or violates the rules and protocols for communication across
the network.
Corresponding Source conveyed, and Installation Information provided, in accord
with this section must be in a format that is publicly documented (and with
an implementation available to the public in source code form), and must require
no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License
by making exceptions from one or more of its conditions. Additional permissions
that are applicable to the entire Program shall be treated as though they
were included in this License, to the extent that they are valid under applicable
law. If additional permissions apply only to part of the Program, that part
may be used separately under those permissions, but the entire Program remains
governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any
additional permissions from that copy, or from any part of it. (Additional
permissions may be written to require their own removal in certain cases when
you modify the work.) You may place additional permissions on material, added
by you to a covered work, for which you have or can give appropriate copyright
permission.
Notwithstanding any other provision of this License, for material you add
to a covered work, you may (if authorized by the copyright holders of that
material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of
sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices displayed
by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring
that modified versions of such material be marked in reasonable ways as different
from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors
of the material; or
e) Declining to grant rights under trademark law for use of some trade names,
trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by
anyone who conveys the material (or modified versions of it) with contractual
assumptions of liability to the recipient, for any liability that these contractual
assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions"
within the meaning of section 10. If the Program as you received it, or any
part of it, contains a notice stating that it is governed by this License
along with a term that is a further restriction, you may remove that term.
If a license document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work material governed
by the terms of that license document, provided that the further restriction
does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place,
in the relevant source files, a statement of the additional terms that apply
to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form
of a separately written license, or stated as exceptions; the above requirements
apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided
under this License. Any attempt otherwise to propagate or modify it is void,
and will automatically terminate your rights under this License (including
any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from
a particular copyright holder is reinstated (a) provisionally, unless and
until the copyright holder explicitly and finally terminates your license,
and (b) permanently, if the copyright holder fails to notify you of the violation
by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently
if the copyright holder notifies you of the violation by some reasonable means,
this is the first time you have received notice of violation of this License
(for any work) from that copyright holder, and you cure the violation prior
to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses
of parties who have received copies or rights from you under this License.
If your rights have been terminated and not permanently reinstated, you do
not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy
of the Program. Ancillary propagation of a covered work occurring solely as
a consequence of using peer-to-peer transmission to receive a copy likewise
does not require acceptance. However, nothing other than this License grants
you permission to propagate or modify any covered work. These actions infringe
copyright if you do not accept this License. Therefore, by modifying or propagating
a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives
a license from the original licensors, to run, modify and propagate that work,
subject to this License. You are not responsible for enforcing compliance
by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization,
or substantially all assets of one, or subdividing an organization, or merging
organizations. If propagation of a covered work results from an entity transaction,
each party to that transaction who receives a copy of the work also receives
whatever licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the Corresponding
Source of the work from the predecessor in interest, if the predecessor has
it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights
granted or affirmed under this License. For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted under
this License, and you may not initiate litigation (including a cross-claim
or counterclaim in a lawsuit) alleging that any patent claim is infringed
by making, using, selling, offering for sale, or importing the Program or
any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License
of the Program or a work on which the Program is based. The work thus licensed
is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled
by the contributor, whether already acquired or hereafter acquired, that would
be infringed by some manner, permitted by this License, of making, using,
or selling its contributor version, but do not include claims that would be
infringed only as a consequence of further modification of the contributor
version. For purposes of this definition, "control" includes the right to
grant patent sublicenses in a manner consistent with the requirements of this
License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent
license under the contributor's essential patent claims, to make, use, sell,
offer for sale, import and otherwise run, modify and propagate the contents
of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement
or commitment, however denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to sue for patent infringement).
To "grant" such a patent license to a party means to make such an agreement
or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free
of charge and under the terms of this License, through a publicly available
network server or other readily accessible means, then you must either (1)
cause the Corresponding Source to be so available, or (2) arrange to deprive
yourself of the benefit of the patent license for this particular work, or
(3) arrange, in a manner consistent with the requirements of this License,
to extend the patent license to downstream recipients. "Knowingly relying"
means you have actual knowledge that, but for the patent license, your conveying
the covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that country
that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work, and grant
a patent license to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of the covered work,
then the patent license you grant is automatically extended to all recipients
of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope
of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
of one or more of the rights that are specifically granted under this License.
You may not convey a covered work if you are a party to an arrangement with
a third party that is in the business of distributing software, under which
you make payment to the third party based on the extent of your activity of
conveying the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by you
(or copies made from those copies), or (b) primarily for and in connection
with specific products or compilations that contain the covered work, unless
you entered into that arrangement, or that patent license was granted, prior
to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied
license or other defenses to infringement that may otherwise be available
to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise)
that contradict the conditions of this License, they do not excuse you from
the conditions of this License. If you cannot convey a covered work so as
to satisfy simultaneously your obligations under this License and any other
pertinent obligations, then as a consequence you may not convey it at all.
For example, if you agree to terms that obligate you to collect a royalty
for further conveying from those to whom you convey the Program, the only
way you could satisfy both those terms and this License would be to refrain
entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to
link or combine any covered work with a work licensed under version 3 of the
GNU Affero General Public License into a single combined work, and to convey
the resulting work. The terms of this License will continue to apply to the
part which is the covered work, but the special requirements of the GNU Affero
General Public License, section 13, concerning interaction through a network
will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the
GNU General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
that a certain numbered version of the GNU General Public License "or any
later version" applies to it, you have the option of following the terms and
conditions either of that numbered version or of any later version published
by the Free Software Foundation. If the Program does not specify a version
number of the GNU General Public License, you may choose any version ever
published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of
the GNU General Public License can be used, that proxy's public statement
of acceptance of a version permanently authorizes you to choose that version
for the Program.
Later license versions may give you additional or different permissions. However,
no additional obligations are imposed on any author or copyright holder as
a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot
be given local legal effect according to their terms, reviewing courts shall
apply local law that most closely approximates an absolute waiver of all civil
liability in connection with the Program, unless a warranty or assumption
of liability accompanies a copy of the Program in return for a fee. END OF
TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively state the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation, either version 3 of the License, or (at your option) any later
version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short notice like
this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it under certain
conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands might
be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary. For
more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General Public
License instead of this License. But first, please read <https://www.gnu.org/
licenses /why-not-lgpl.html>.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the
successor of the GNU Library Public License, version 2, hence the version
number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software Foundation
and other authors who decide to use it. You can use it too, but we suggest
you first think carefully about whether this license or the ordinary General
Public License is the better strategy to use in any particular case, based
on the explanations below.
When we speak of free software, we are referring to freedom of use, not price.
Our General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish); that you receive source code or can get it if you want it; that you
can change the software and use pieces of it in new free programs; and that
you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors
to deny you these rights or to ask you to surrender these rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
We protect your rights with a two-step method: (1) we copyright the library,
and (2) we offer you this license, which gives you legal permission to copy,
distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict the
users of a free program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this
license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public License,
applies to certain designated libraries, and is quite different from the ordinary
General Public License. We use this license for certain libraries in order
to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared
library, the combination of the two is legally speaking a combined work, a
derivative of the original library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for linking other
code with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over competing
non-free programs. These disadvantages are the reason we use the ordinary
General Public License for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the
widest possible use of a certain library, so that it becomes a de-facto standard.
To achieve this, non-free programs must be allowed to use the library. A more
frequent case is that a free library does the same job as widely used non-free
libraries. In this case, there is little to gain by limiting the free library
to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. For
example, permission to use the GNU C Library in non-free programs enables
many more people to use the whole GNU operating system, as well as its variant,
the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a modified
version of the Library.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, whereas the latter must be combined with the library in
order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General
Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (1) uses at run time a copy of the library
already present on the user's computer system, rather than copying library
functions into the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as the modified
version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
e) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the materials to be distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.
< one line to give the library's name and an idea of what it does. >
Copyright (C) < year > < name of author >
This library is free software; you can redistribute it and/or modify it under
the terms of the GNU Lesser General Public License as published by the Free
Software Foundation; either version 2.1 of the License, or (at your option)
any later version.
This library is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more
details.
You should have received a copy of the GNU Lesser General Public License along
with this library; if not, write to the Free Software Foundation, Inc., 51

on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the library, if necessary. Here
is a sample; alter the names:

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates the terms
and conditions of version 3 of the GNU General Public License, supplemented
by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser General
Public License, and the "GNU GPL" refers to version 3 of the GNU General Public
License.
"The Library" refers to a covered work governed by this License, other than
an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided by the
Library, but which is not otherwise based on the Library. Defining a subclass
of a class defined by the Library is deemed a mode of using an interface provided
by the Library.
A "Combined Work" is a work produced by combining or linking an Application
with the Library. The particular version of the Library with which the Combined
Work was made is also called the "Linked Version".
The "Minimal Corresponding Source" for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the
Combined Work that, considered in isolation, are based on the Application,
and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the object
code and/or source code for the Application, including any data and utility
programs needed for reproducing the Combined Work from the Application, but
excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License without
being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a facility
refers to a function or data to be supplied by an Application that uses the
facility (other than as an argument passed when the facility is invoked),
then you may convey a copy of the modified version:
a) under this License, provided that you make a good faith effort to ensure
that, in the event an Application does not supply the function or data, the
facility still operates, and performs whatever part of its purpose remains
meaningful, or
b) under the GNU GPL, with none of the additional permissions of this License
applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from a header
file that is part of the Library. You may convey such object code under terms
of your choice, provided that, if the incorporated material is not limited
to numerical parameters, data structure layouts and accessors, or small macros,
inline functions and templates (ten or fewer lines in length), you do both
of the following:
a) Give prominent notice with each copy of the object code that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that, taken together,
effectively do not restrict modification of the portions of the Library contained
in the Combined Work and reverse engineering for debugging such modifications,
if you also do each of the following:
a) Give prominent notice with each copy of the Combined Work that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during execution, include
the copyright notice for the Library among these notices, as well as a reference
directing the user to the copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this License,
and the Corresponding Application Code in a form suitable for, and under terms
that permit, the user to recombine or relink the Application with a modified
version of the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
1) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (a) uses at run time a copy of the Library
already present on the user's computer system, and (b) will operate properly
with a modified version of the Library that is interface-compatible with the
Linked Version.
e) Provide Installation Information, but only if you would otherwise be required
to provide such information under section 6 of the GNU GPL, and only to the
extent that such information is necessary to install and execute a modified
version of the Combined Work produced by recombining or relinking the Application
with a modified version of the Linked Version. (If you use option 4d0, the
Installation Information must accompany the Minimal Corresponding Source and
Corresponding Application Code. If you use option 4d1, you must provide the
Installation Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the Library side
by side in a single library together with other library facilities that are
not Applications and are not covered by this License, and convey such a combined
library under terms of your choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities, conveyed under the
terms of this License.
b) Give prominent notice with the combined library that part of it is a work
based on the Library, and explaining where to find the accompanying uncombined
form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions of the
GNU Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library as you
received it specifies that a certain numbered version of the GNU Lesser General
Public License "or any later version" applies to it, you have the option of
following the terms and conditions either of that published version or of
any later version published by the Free Software Foundation. If the Library
as you received it does not specify a version number of the GNU Lesser General
Public License, you may choose any version of the GNU Lesser General Public
License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide whether
future versions of the GNU Lesser General Public License shall apply, that
proxy's public statement of acceptance of any version is permanent authorization
for you to choose that version for the Library.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the
successor of the GNU Library Public License, version 2, hence the version
number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public Licenses are intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software Foundation
and other authors who decide to use it. You can use it too, but we suggest
you first think carefully about whether this license or the ordinary General
Public License is the better strategy to use in any particular case, based
on the explanations below.
When we speak of free software, we are referring to freedom of use, not price.
Our General Public Licenses are designed to make sure that you have the freedom
to distribute copies of free software (and charge for this service if you
wish); that you receive source code or can get it if you want it; that you
can change the software and use pieces of it in new free programs; and that
you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors
to deny you these rights or to ask you to surrender these rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes
to the library and recompiling it. And you must show them these terms so they
know their rights.
We protect your rights with a two-step method: (1) we copyright the library,
and (2) we offer you this license, which gives you legal permission to copy,
distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict the
users of a free program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this
license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public License,
applies to certain designated libraries, and is quite different from the ordinary
General Public License. We use this license for certain libraries in order
to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared
library, the combination of the two is legally speaking a combined work, a
derivative of the original library. The ordinary General Public License therefore
permits such linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for linking other
code with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over competing
non-free programs. These disadvantages are the reason we use the ordinary
General Public License for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the
widest possible use of a certain library, so that it becomes a de-facto standard.
To achieve this, non-free programs must be allowed to use the library. A more
frequent case is that a free library does the same job as widely used non-free
libraries. In this case, there is little to gain by limiting the free library
to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. For
example, permission to use the GNU C Library in non-free programs enables
many more people to use the whole GNU operating system, as well as its variant,
the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a modified
version of the Library.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code derived
from the library, whereas the latter must be combined with the library in
order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General
Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means either
the Library or any derivative work under copyright law: that is to say, a
work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications
to it. For a library, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus
the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program
using the Library is not restricted, and output from such a program is covered
only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends
on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to
the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all
of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of
data to be supplied by an application program that uses the facility, other
than as an argument passed when the facility is invoked, then you must make
a good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore, Subsection
2d requires that any application-supplied function or table used by this function
must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be
on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works based
on the Library.
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the
ordinary GNU General Public License, version 2, instead of to this License.
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy,
so the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library
into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though
third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it,
is called a "work that uses the Library". Such a work, in isolation, is not
a derivative work of the Library, and therefore falls outside the scope of
this License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions
of the Library), rather than a "work that uses the library". The executable
is therefore covered by this License. Section 6 states terms for distribution
of such executables.
When a "work that uses the Library" uses material from a header file that
is part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute
the object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work
that uses the Library" with the Library to produce a work containing portions
of the Library, and distribute that work under terms of your choice, provided
that the terms permit modification of the work for the customer's own use
and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library
is used in it and that the Library and its use are covered by this License.
You must supply a copy of this License. If the work during execution displays
copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License.
Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source
code for the Library including whatever changes were used in the work (which
must be distributed under Sections 1 and 2 above); and, if the work is an
executable linked with the Library, with the complete machine-readable "work
that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who changes the contents
of definitions files in the Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (1) uses at run time a copy of the library
already present on the user's computer system, rather than copying library
functions into the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as the modified
version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years,
to give the same user the materials specified in Subsection 6a, above, for
a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated
place, offer equivalent access to copy the above specified materials from
the same place.
e) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable
from it. However, as a special exception, the materials to be distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating system.
Such a contradiction means you cannot use both them and the Library together
in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by
this License, and distribute such a combined library, provided that the separate
distribution of the work based on the Library and of the other library facilities
is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to
copy, modify, sublicense, link with, or distribute the Library is void, and
will automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the Library
(or any work based on the Library), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor
to copy, distribute, link with or modify the Library subject to these terms
and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not distribute the Library at all. For example, if a
patent license would not permit royalty-free redistribution of the Library
by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely
from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software
distributed through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Library under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of
the Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies
a version number of this License which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version
ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the author
to ask for permission. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.
< one line to give the library's name and an idea of what it does. >

the terms of the GNU Lesser General Public License as published by the Free
Software Foundation; either version 2.1 of the License, or (at your option)
any later version.
This library is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more
details.

with this library; if not, write to the Free Software Foundation, Inc., 51

on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the library, if necessary. Here
is a sample; alter the names:

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates the terms
and conditions of version 3 of the GNU General Public License, supplemented
by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser General
Public License, and the "GNU GPL" refers to version 3 of the GNU General Public
License.
"The Library" refers to a covered work governed by this License, other than
an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided by the
Library, but which is not otherwise based on the Library. Defining a subclass
of a class defined by the Library is deemed a mode of using an interface provided
by the Library.
A "Combined Work" is a work produced by combining or linking an Application
with the Library. The particular version of the Library with which the Combined
Work was made is also called the "Linked Version".
The "Minimal Corresponding Source" for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the
Combined Work that, considered in isolation, are based on the Application,
and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the object
code and/or source code for the Application, including any data and utility
programs needed for reproducing the Combined Work from the Application, but
excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License without
being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a facility
refers to a function or data to be supplied by an Application that uses the
facility (other than as an argument passed when the facility is invoked),
then you may convey a copy of the modified version:
a) under this License, provided that you make a good faith effort to ensure
that, in the event an Application does not supply the function or data, the
facility still operates, and performs whatever part of its purpose remains
meaningful, or
b) under the GNU GPL, with none of the additional permissions of this License
applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from a header
file that is part of the Library. You may convey such object code under terms
of your choice, provided that, if the incorporated material is not limited
to numerical parameters, data structure layouts and accessors, or small macros,
inline functions and templates (ten or fewer lines in length), you do both
of the following:
a) Give prominent notice with each copy of the object code that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that, taken together,
effectively do not restrict modification of the portions of the Library contained
in the Combined Work and reverse engineering for debugging such modifications,
if you also do each of the following:
a) Give prominent notice with each copy of the Combined Work that the Library
is used in it and that the Library and its use are covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during execution, include
the copyright notice for the Library among these notices, as well as a reference
directing the user to the copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this License,
and the Corresponding Application Code in a form suitable for, and under terms
that permit, the user to recombine or relink the Application with a modified
version of the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
1) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (a) uses at run time a copy of the Library
already present on the user's computer system, and (b) will operate properly
with a modified version of the Library that is interface-compatible with the
Linked Version.
e) Provide Installation Information, but only if you would otherwise be required
to provide such information under section 6 of the GNU GPL, and only to the
extent that such information is necessary to install and execute a modified
version of the Combined Work produced by recombining or relinking the Application
with a modified version of the Linked Version. (If you use option 4d0, the
Installation Information must accompany the Minimal Corresponding Source and
Corresponding Application Code. If you use option 4d1, you must provide the
Installation Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the Library side
by side in a single library together with other library facilities that are
not Applications and are not covered by this License, and convey such a combined
library under terms of your choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities, conveyed under the
terms of this License.
b) Give prominent notice with the combined library that part of it is a work
based on the Library, and explaining where to find the accompanying uncombined
form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions of the
GNU Lesser General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Library as you
received it specifies that a certain numbered version of the GNU Lesser General
Public License "or any later version" applies to it, you have the option of
following the terms and conditions either of that published version or of
any later version published by the Free Software Foundation. If the Library
as you received it does not specify a version number of the GNU Lesser General
Public License, you may choose any version of the GNU Lesser General Public
License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide whether
future versions of the GNU Lesser General Public License shall apply, that
proxy's public statement of acceptance of any version is permanent authorization
for you to choose that version for the Library.

# KDE Connect for the Steam Frame
Frame Control's keyboard and trackpad work through KDE Connect running on the
Frame. The Frame doesn't come with it, so Frame Control ships it: the six
packages below, unchanged, exactly as Valve builds them for the Frame's
SteamOS (aarch64, packaged by "GitLab CI Package Builder
<ci-package-builder-1@steamos.cloud>"). On first use, Frame Control copies them
to the Frame over SSH and unpacks them into
`~/.local/share/frame-control/kdeconnect`.
They are separate programs and libraries under their own licences, listed
below; their licence texts are in `LICENSES/<package>/`. Frame Control itself
is MIT-licensed. It doesn't link to or include any of this code: it starts
`kdeconnectd` and talks to it over KDE Connect's network protocol, as a phone
would.

## Source code
Each source package is Valve's, copied unchanged: the upstream release
tarball (with its signature where upstream signs it), the PKGBUILD Valve built
from, and the signing keys. None of them carry patches. Frame Control
publishes them next to the binaries, in the
[kdeconnect-frame-24.02.2-1 release](https://github.com/saphid/frame-control/releases/tag/kdeconnect-frame-24.02.2-1),
so the source is available from the same place as the binaries for as long as
Frame Control distributes them. `packages.json` pins each binary and source
package by SHA-256.
If a link ever stops working, open an issue at
https://github.com/saphid/frame-control/issues and we'll send you the source.
## Replacing them
These are ordinary files in your home folder on the Frame: you may replace
them with your own builds, and Frame Control will use whatever `kdeconnectd`
is at `~/.local/share/frame-control/kdeconnect/root/usr/lib/kdeconnectd`
(or the Frame's own `/usr/lib/kdeconnectd`, if SteamOS ever ships one).
Deleting `root/.frame-control-packages` there makes Frame Control copy its
bundled build back on next use.

# Frame OpenXR compatibility API layer
`XR_APILAYER_FRAME_compat` is an APK-local implicit API layer for Steam Frame's
OpenXR 1.0 Android runtime. It translates selected 1.1 functionality; it is not
a conformant replacement for a complete 1.1 runtime. Device facts are in
[../../docs/vr-apks.md](../../docs/vr-apks.md). No headset was contacted during
implementation. Loading, Valve-layer coexistence, controller usability, and
Wolvic startup/rendering on Lepton remain **unverified on device**.
## Behavior
- The negotiated `createApiLayerInstance` hook handles `xrCreateInstance`.
API requests >= 1.1 become `XR_API_VERSION_1_0` (1.0.63 with these headers),
rather than carrying an arbitrary application's patch into the 1.0 request.
Requests below 1.1 are unchanged. The loader may reject future API versions
before any layer runs.
- Enumerate downstream extensions through the **next layer's** GIPA before
creation. Only advertised promoted extensions are added, with duplicates
removed. All other application extensions remain, except the two stubs below.
Log added, stubbed and missing extensions with tag `FrameXrCompat`.
- Missing `XR_KHR_android_thread_settings` is advertised and accepted;
`xrSetAndroidApplicationThreadKHR` logs and returns success without changing
thread scheduling. Missing `XR_OCULUS_android_session_state_enable` is
advertised and accepted, with no commands or additional session behavior.
If downstream supports either extension, preserve it and its real commands.
Stubbing these capabilities is intentionally limited to accepting the app's
request; it does not provide Meta services.
- The manifest's `instance_extensions` makes both stubs visible during the
loader's pre-instance enumeration and validation. The layer also exposes
an enumeration implementation with count/capacity handling. Before a next
dispatch is available it can enumerate only its own extensions; normal app
global enumeration is performed by the loader, merging runtime and manifest
entries. See [loader_core.cpp L106–145](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/loader_core.cpp#L106)
and [manifest parsing L549–558](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/manifest_file.cpp#L549).
- Unknown missing extensions are never silently removed. Khronos may reject
them **before** entering the layer and name them in `OpenXR-Loader` logs
([loader_instance.cpp L149–176](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/loader_instance.cpp#L149)).
If they reach this layer, it logs their names and preserves them for the
downstream failure.
- `xrLocateSpaces` dispatches to `xrLocateSpacesKHR` per session/instance.
This is the only command added in 1.1. The three relevant structure types
(`SPACES_LOCATE_INFO`, `SPACE_LOCATIONS`, `SPACE_VELOCITIES`) and their KHR
versions are **numeric aliases**, and the structs are typedef aliases in
these headers. Explicit type conversion of local input/output copies is
therefore an identity conversion; the velocity chain passes through without
mutating its types or linkage. Output arrays remain shared and receive the
runtime's results, including on error; caller struct headers remain intact.
- With palm pose enabled, rewrite both hand paths ending in
`/input/grip_surface/pose` to `/input/palm_ext/pose` in `xrStringToPath` and
in binding suggestions (including paths obtained before this layer rewrote
them). Unknown paths are left alone.
- `xrGetInstanceProperties` and unrelated commands pass through. The real
runtime's identity is not spoofed. Dispatch tables and session ownership are
locked, and removed after successful destruction. Downstream calls occur
outside the lock.
## Spec basis and interaction profiles
The pinned [1.1 promotions appendix, versions.adoc L16–156](https://github.com/KhronosGroup/OpenXR-Docs/blob/release-1.1.63/specification/sources/chapters/versions.adoc#L16)
includes a generated promotion list. Its source is the
[1.1.63 XML registry](https://github.com/KhronosGroup/OpenXR-Docs/blob/release-1.1.63/specification/registry/xr.xml),
selecting `extension[@promotedto='XR_VERSION_1_1']`. The full list implemented:
| Promoted extension | Handling |
| --- | --- |
| `XR_KHR_locate_spaces` | Enable if advertised; core command alias |
| `XR_EXT_local_floor` | Enable if advertised; reference-space enum is an alias |
| `XR_EXT_uuid` | Enable if advertised; type alias, no commands |
| `XR_EXT_palm_pose` | Enable if advertised; rewrite grip-surface paths |
| `XR_VARJO_quad_views` | Enable if advertised; view-configuration enum alias, support remains optional |
| `XR_EXT_samsung_odyssey_controller` | Enable if advertised |
| `XR_EXT_hp_mixed_reality_controller` | Enable if advertised |
| `XR_HTC_vive_cosmos_controller_interaction` | Enable if advertised |
| `XR_HTC_vive_focus3_controller_interaction` | Enable if advertised |
| `XR_ML_ml2_controller_interaction` | Enable if advertised |
| `XR_FB_touch_controller_pro` | Enable if advertised; old profile still usable |
| `XR_META_touch_controller_plus` | Enable if advertised; old profile still usable |
| `XR_BD_controller_interaction` | Enable if advertised |
| `XR_KHR_maintenance1` | Enable if advertised (included in the pinned registry's promotion list) |
`XR_EXT_hand_interaction` is **not** promoted to 1.1. Preserve it if requested;
it is not auto-enabled merely because the runtime advertises it. The parent
provided its availability; the device notes list extensions non-exhaustively.
The registry's `XR_VERSION_1_1` feature introduces 13 profile paths. For
Samsung Odyssey, HP mixed reality, HTC Cosmos/Focus3, ML2 and the three
ByteDance Pico profiles, drop a whole suggestion call with success when the
corresponding extension is absent. Keep it when the extension is enabled.
Drop the five new Meta paths: `touch_pro_controller`, `touch_plus_controller`,
`touch_controller_rift_cv1`, `touch_controller_quest_1_rift_s`, and
`touch_controller_quest_2`. The verified runtime notes do not list these;
Pro/Plus promotion also renames several components, so the old extension's
presence alone does not prove support for the new profile. This layer does
not implement those component conversions. Existing old Pro/Plus profile
paths are passed through if the app uses them.
Preserve the documented `oculus/touch_controller`, `khr/simple_controller`,
`valve/frame_controller` and original PC profile paths. The notes' "usual PC
controllers" is not a complete enumerated list: availability of promoted PC
profiles is inferred from the runtime's extension advertisement, not invented
from that phrase. OpenXR has no general profile enumeration API. Dropping
suggestions prevents an unsupported 1.1 profile from aborting initialization;
it does not create bindings, so the app must also suggest a supported fallback.
## Headers and licensing
The required public headers (`openxr.h`, `openxr_platform.h`,
`openxr_platform_defines.h`) are unmodified from
[OpenXR-SDK release-1.1.63](https://github.com/KhronosGroup/OpenXR-SDK/tree/release-1.1.63/include/openxr),
commit [f2448a8](https://github.com/KhronosGroup/OpenXR-SDK/commit/f2448a8797c85814aa892efc1ab8707900fbcc78).
The requested filename `loader_interfaces.h` no longer exists in 1.1 SDK
releases: negotiation was ratified and moved to `openxr_loader_negotiation.h`
in 1.0.33 ([spec history L166–186](https://github.com/KhronosGroup/OpenXR-Docs/blob/release-1.1.63/specification/sources/chapters/versions.adoc#L166)).
To retain that requested interface filename, the layer uses the unmodified,
ABI-compatible [last legacy header from SDK-Source release-1.0.32](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.0.32/src/common/loader_interfaces.h).
Only these four headers are vendored. They offer Apache-2.0 OR MIT; this
vendoring uses Apache-2.0, reproduced in [vendor/LICENSE](vendor/LICENSE).
## Android discovery and coexistence
**Minimum asset-discovery loader release: 1.0.25 (2022-09-02).** Its
[release commit, 15c3d8e](https://github.com/KhronosGroup/OpenXR-SDK-Source/commit/15c3d8eb99994e5365d6b6f96eefaf4c51a65a9d)
explicitly announces APK-packaged API layers;
[manifest_file.cpp L665–723](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.0.25/src/loader/manifest_file.cpp#L665)
implements discovery, and [L934–940](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.0.25/src/loader/manifest_file.cpp#L934)
adds asset manifests after filesystem manifests. This is not a 1.1-only feature.
**For an app requesting API 1.1, use a 1.1 loader (first release 1.1.36) or
newer.** A 1.0 loader rejects the request before the layer can downgrade it;
see [loader_core.cpp L217–230](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/loader_core.cpp#L217).
The runtime can remain 1.0.
Source inspection at release-1.1.63 confirms:
- [manifest_file.cpp L720–783](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/manifest_file.cpp#L720)
uses the initialized Android asset manager and scans
`openxr/1/api_layers/implicit.d/` for JSON. The application must initialize
the loader with its Android context (`xrInitializeLoaderKHR`). In the APK,
the entry is `assets/openxr/1/api_layers/implicit.d/XrApiLayer_FRAME_compat.json`.
- A bare `library_path`, as used here, is **not explicitly concatenated** with
`nativeLibraryDir`. [L878–900](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/manifest_file.cpp#L878)
leaves a bare name for normal dynamic-linker search in the application's
namespace (including its native library directory). Relative paths with a
slash use [LocateLibraryInAssets L943–952](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/manifest_file.cpp#L943),
which resolves against `GetAndroidNativeLibraryDir()`.
[loader_init_data.cpp L87–96](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/loader_init_data.cpp#L87)
obtains the asset manager and `ApplicationInfo.nativeLibraryDir` via JNI.
Wolvic's supplied manifest has `android:extractNativeLibs="true"`.
- [android_utilities.cpp L267–322](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/android_utilities.cpp#L267)
handles runtime broker discovery, not APK layer discovery. Its
`native_lib_dir + so_filename` and `dlopen` refer to the runtime package.
They must not be confused with the app's layer library resolution.
- [manifest_file.cpp L1008–1023](https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/release-1.1.63/src/loader/manifest_file.cpp#L1008)
retains filesystem manifests and then appends asset manifests. This leaves
`/vendor`'s `XR_APILAYER_VALVE_fdm_injection` discoverable. This layer advances
`nextInfo` exactly once, uses next-layer GIPA, preserves the rest of the
create-info chain and never opens `vrclient.so` directly. No environment
layer-list override or assumed ordering is needed.
`DISABLE_FRAME_XR_COMPAT` is the manifest's disable environment variable.
Leave it unset to activate the implicit layer. No `enable_environment` is
required.
## Rebuild and verify
NDK **r30 / 30.0.16248370**, installed at
`~/Library/Android/ndk/30.0.16248370`, was the latest stable/LTS package shown
by the [Android download page](https://developer.android.com/ndk/downloads)
on 2026-09-28. Downloaded
[android-ndk-r30-darwin.dmg](https://dl.google.com/android/repository/android-ndk-r30-darwin.dmg)
(1,072,970,961 bytes). The page publishes SHA-1, not SHA-256:
```
expected: 48591224b6657f46eebbc9d95d4af09bbed8d107
actual: 48591224b6657f46eebbc9d95d4af09bbed8d107 (PASS)
```
Mounted read-only with `hdiutil`; copied
`AndroidNDK16248370.app/Contents/NDK` into that version directory. Despite the
`darwin-x86_64` toolchain directory name, clang is universal arm64/x86_64 and
ran on this Apple Silicon Mac.
```sh
frame/openxr-compat/build.sh
# Or set ANDROID_NDK_HOME to an installed NDK.
cmake -S frame/openxr-compat -B frame/openxr-compat/build-host -G Ninja
cmake --build frame/openxr-compat/build-host
ctest --test-dir frame/openxr-compat/build-host --output-on-failure
```
The script produces arm64-v8a / android-24, C++17, `-O2`, static libc++, hidden
internal symbols, stripped output, and `-Wl,-z,max-page-size=16384`.
The committed prebuilt is `prebuilt/arm64-v8a/libXrApiLayer_FRAME_compat.so`.
Its SHA-256 is recorded below with the APK checks.
[Host test output](evidence/ctest.txt): two tests passed, covering pure logic
and the actual layer with a fake next layer and host-only log/JNI shims.
[Full llvm-readelf -d -s -l output](evidence/readelf.txt) records three LOAD
segments aligned `0x4000`, only `xrNegotiateLoaderApiLayerInterface` exported,
and only `libc.so`, `libm.so`, `libdl.so`, `liblog.so` as NEEDED libraries.
All 46 undefined imports are versioned `@LIBC` except `__android_log_print`.
There is no `libc++_shared.so` dependency and no unstripped `.symtab`.
No independent model review was run: the task explicitly prohibits delegation.
No `CODING_STANDARDS.md` exists in this worktree or the primary worktree.
## Wolvic injection artifact (Mac only)
Copied `/tmp/vrapk/wq-dec` to `/tmp/vrapk/wq-layer-dec`; retained its existing
LAUNCHER fix and native-library extraction setting. Added only:
```
assets/openxr/1/api_layers/implicit.d/XrApiLayer_FRAME_compat.json
lib/arm64-v8a/libXrApiLayer_FRAME_compat.so
```
Built using `/tmp/vrapk/jdk/Contents/Home/bin/java` and
`/tmp/vrapk/apktool_3.0.3.jar`, then signed in place using
`/tmp/vrapk/uber-apk-signer-1.3.0.jar --overwrite` (embedded debug certificate):
```sh
/tmp/vrapk/jdk/Contents/Home/bin/java -jar /tmp/vrapk/apktool_3.0.3.jar \
b /tmp/vrapk/wq-layer-dec -o /tmp/vrapk/wolvic-quest-compat.apk
/tmp/vrapk/jdk/Contents/Home/bin/java -jar /tmp/vrapk/uber-apk-signer-1.3.0.jar \
-a /tmp/vrapk/wolvic-quest-compat.apk --overwrite
/tmp/vrapk/jdk/Contents/Home/bin/java -jar /tmp/vrapk/uber-apk-signer-1.3.0.jar \
-a /tmp/vrapk/wolvic-quest-compat.apk --onlyVerify
```
Final APK: `/tmp/vrapk/wolvic-quest-compat.apk` (not committed).
The bundled `lib/arm64-v8a/libopenxr_loader.so` is byte-for-byte unchanged.
Its strings include both `openxr/1/api_layers/implicit.d/` and
`openxr/1/api_layers/explicit.d/`, `AddManifestFilesAndroid` error messages,
and `xrLocateSpaces`. Thus it contains APK asset discovery and evidence of
1.1 command support. Its exact upstream release number was not established
from the binary; runtime execution of those paths remains unverified.
Prebuilt library SHA-256:
```
479d31c374f137906e03f73209b581d65d7e6a41b8476e6425fa55a6aa40bd68
```
APK SHA-256:
```
355a681625e38b71563dcffecb031799eff27894d6ab910a659bace057e82c1f
```
Final `--onlyVerify` exited 0: zip alignment verified, v2/v3 signatures
verified, one APK processed and zero errors. ZIP readback confirmed that the
injected library and manifest match the committed inputs, the loader is
unchanged, and the binary Android manifest retains the LAUNCHER category.
