saphidandClaude Opus 5.5 41f08ac9a2 Bundled KDE Connect: one safety net for every launch failure
Any unexpected error while launching clears the launch and reports it, so
the pad can always be started again; the temporary stderr file is made
inside the handled path and a failure reading it is tolerated.

saphidandClaude Opus 5.5 98a5ec45bb Bundled KDE Connect: tidying up can't leave the pad stuck starting
discard() swallows OSError as well as Failure, so a launch that fails and
can't remove its copy still reports the error and can be started again.

saphidandClaude Opus 5.5 e4421d966a Bundled KDE Connect: the server owns a copy until its agent speaks
The agent holds its copy from its first status line on and tidies it up
however it ends. Before that (a launch error, or stopped before the agent
ran) the server removes the copy itself. discard() only ever removes
incoming copies, never the iPhone bundle's own. The retry race test waits
for both contenders' decisions instead of sleeping.

saphidandClaude Opus 5.5 efffd72c52 Bundled KDE Connect: no copy left behind by a stop or a local read error
- A start turned off while copying removes the copy instead of starting an
  agent that would be killed before it could tidy up.
- A local read error while copying removes the partial copy too.
- The retry race test holds the new start until the retry has decided, so
  it fails every time without the fix (checked 3/3), not by luck.

saphidandClaude Opus 5.5 bda9d77d2d Mac in the headset: USB route keeps a configured host-key alias and falls back to the network
Review round 12: a failed USB-C tunnel now retries the normal path; an
existing HostKeyAlias wins; --host with --usb is rejected; the Steam
desktop-streaming claim is now 'untested' (Valve documents the desktop
showing when a game loses focus); the Show/cleanup overlap test blocks
for real (it fails without the lock). Verified live: with the cable out,
the route is the normal path.

saphidandClaude Opus 5.5 d5e8193ce5 Bundled KDE Connect: tidy the copied packages however a start ends
- Each start keeps its copy (holding a lock on it) until it ends, however
  it ends, then removes it; a restart can still unpack it.
- The server removes a partial copy when copying fails.
- Other copies are removed only when unlocked and over an hour old.
- Tests: a start racing the need-packages retry (one agent, not two), a
  restart that must unpack its copy, a held copy surviving the sweep.
  Both regression tests fail without their fix.

saphidandClaude Opus 5.5 4fae62ba14 Mac in the headset: use the Frame's USB-C network when plugged in; Steam streaming findings
- Plugged into the Mac, the Frame is a USB network device ("Steam Frame",
  usb0 at ~0.9 ms). The tunnel uses it when the Frame's usb0 answers,
  with the usual host key; otherwise the normal path. Interleaved runs:
  content p50 7 vs 10 ms, click to drawn 17 vs 27 ms, scroll p95 23 vs
  31-37 ms. FRAME_MACVIEW_USB=0 turns it off; the card says "over USB-C".
- Bench: --usb, and the route is recorded per run.
- Docs: Steam's own streaming (no SteamVR host on macOS; Remote Play pairs
  but streams games, not windows; test blocked); the Frame's USB network;
  the 2026-09-28 health-check boot-loop recurrence.

saphidandClaude Opus 5.5 6765fbcb20 Bundled KDE Connect: close the races the second review found
- The need-packages retry only runs if no start() has taken over, so two
  agents can't end up running for one session.
- Each copy goes to its own incoming folder; the agent removes its own once
  connected (and any a cancelled start left over an hour ago), so a stopped
  start can't delete files another is copying or still needs.
- A missing package folder means need-packages, not an error.
- Tests keep fake agents running, so they check ready and which agent owns
  the session, plus a bounded retry and the tidy rule.

saphidandClaude Opus 5.5 75b2478a55 Bundled KDE Connect: fixes from review
- iPhone build fails if the bundle can't be made, instead of shipping a
  stale archive with an empty version.
- A different build that another device is using right now is left running
  and replaced once nobody is, rather than stopped under them.
- If what's installed changed after the server looked, the agent asks for
  the packages (need-packages) and the server copies them and starts again.
- The installed-build check sends bytes, so Windows' CRLF can't break it.
- Starting again while a stopped start is still copying launches anew;
  concurrent copies use their own temporary names.

Review round 10: a Show replacing its own stream could have its new viewer
ended by the cleanup; a viewer reset left the delayed relay pending.

saphidandClaude Opus 5.5 7f769ca2f0 Mac in the headset: end the Frame's viewer browser after Stop; relay fixes
- Chromium on the Frame outlived its last viewer window (verified: 11
  processes left after a run). Once nothing is shown, Stop ends it, unless
  Show was pressed again meanwhile; its profile is Frame Control's own.
- Relay --delay: if the agent side fails, close the viewer side too
  (review round 9).
- Docs: the final scroll run captured 57 fps; don't blame ScreenCaptureKit.

saphidandClaude Opus 5.5 5bf1268c82 Ship KDE Connect inside Frame Control instead of downloading it on the Frame
The keyboard and trackpad no longer fetch KDE Connect from Valve's package
repository on the Frame. The desktop apps and the iPhone app's Frame bundle
carry Valve's arm64 build of kdeconnect 24.02.2-1 and the five libraries it
links (kcontacts, kpeople, modemmanager-qt, pulseaudio-qt, libfakekey),
pinned by SHA-256 in frame/kdeconnect/packages.json and downloaded at build
time from the kdeconnect-frame-24.02.2-1 release, which also holds Valve's
complete source package for each.

On first use the computer copies them over its SSH connection (the iPhone
bundle already has them on the Frame); the agent checks each SHA-256,
unpacks them and stamps which build it is, so later starts copy nothing.
No internet on the Frame, 3.6 MB instead of 8 MB, 18 MB unpacked instead of
82 MB (ModemManager and friends were packaging-only dependencies).

GPL/LGPL compliance: frame/kdeconnect/NOTICE.md names each exact version,
licence and source; per-project licence texts in frame/kdeconnect/LICENSES;
THIRD_PARTY_NOTICES.md; an About and licences dialog in the app.

Review round 8 (GPT-6 Astra xhigh): --delay paused upstream reads, so busy
streams saw 30-60 ms instead of 30. Verified locally: 60-62 ms round trip

saphidandClaude Opus 5.5 9e4dcdd147 Mac in the headset: measure every frame, adapt to the network, separate windows
- Per-frame timing on the Mac's clock (capture, encode, network, decode,
  draw), viewer clock sync and reports, input echo, /stats and a HUD.
- scripts/macview-bench.py: repeatable runs on the real Frame, a shaping
  relay (no sudo), interleaved A/B between agent settings; results in
  bench/results/.
- Adaptive controller: ack-based send gate with jitter-aware slack, AIMD
  bitrate that knows when a stream is app-limited, fps then size tiers.
  On a 50->3->50 Mbit/s step, scroll p95 went from 4.7 s to 72 ms; no cost
  on a clean link.
- Separate mode: real AppKit event loop (HiDPI and NSScreen now work),
  cropped capture for fixed-size windows, windows kept on their display,
  graceful quit restores windows; stop/start races fixed.
- Encoder timeline clamp (no oversized frame after a pause).
- Frame Control shows each live stream's fps, delay, bitrate and tier.

Reviewed by GPT-6 Astra xhigh (read-only), 7 rounds; findings fixed.

saphid 6217b5f2fa Merge remote-tracking branch 'origin/main' into frame-input 2026-09-28 17:43:27 +10:00
saphidandClaude Opus 5.5 b9e31178f3 Keyboard and trackpad for the Frame, through its own KDE Connect
Home → Keyboard and trackpad, in every version of Frame Control (Mac,
Windows, Linux, iPhone, iPad) with nothing to install on the device in
your hand. On a phone: a trackpad (drag, tap, two-finger scroll and
right-click) and a field that types on the Frame. On a computer: click
the pad to pass the mouse and keyboard through; Esc to stop.

First-party route: ui/frame_input_agent.py runs on the Frame and talks
KDE Connect's LAN protocol (v7) to kdeconnectd as if it were a phone.
KDE Connect isn't on the image, but Valve's package repository has it;
the agent fetches it and four libraries into ~ (no root, survives
updates), starts it, pairs by itself (accepting over D-Bus), and stops
it again when the last device disconnects. Each device has its own
identity; a stuck KDE Connect is restarted once.

Verified against the real Frame (SteamOS 0.4.1): first-time install,
pairing, pointer moves from the Mac's server and the iPhone app
(Simulator), Mac and iPhone at once, two installs at once, a frozen
daemon replaced, and the daemon stopping when the app quits.

except per-event delivery acknowledgement (documented known limit).

saphidandClaude Opus 5.5 a3c6e5c984 Mac in the headset: stream Mac windows and screens into the Frame as panels
Frame Control can now show any Mac window, or a whole screen, as its own
SteamVR panel on the Steam Frame (Tools -> Mac in the headset, macOS only).
Place it with the SteamVR dashboard; the laser clicks and scrolls, and the
Mac's own keyboard types.

- mac/frame-mac-view (Swift, no dependencies): ScreenCaptureKit capture per
  window or display, VideoToolbox H.264 with low-latency rate control (JPEG
  fallback), a loopback HTTP/WebSocket server, CGEvent/AX input playback,
  and a display-awake assertion while anyone watches.
- ui/frame_macview.py: starts the agent, runs an ssh -R tunnel with a
  supervisor that reopens it on the same port, and launches a Chromium app
  window per stream on gamescope's :0, tagged with STEAM_GAME for its own panel.
- Frame Control's key never leaves the Mac: viewers get single-use,
  per-source tickets and reconnect keys that Stop revokes.
- ui/mac-view.html: WebCodecs decode, keyframe recovery, pointer/wheel/keys back.
- Bundled in the Mac app build; tests/test_macview.py builds and drives the
  agent on macOS.

Verified on the Frame (build 20260925.6191901) with the test pattern: panel
in about 1.5 s, about 60 fps, Mac-to-window about 11-17 ms, tunnel recovery
in 4 s. Laser input and real window capture still need a person in the headset.

Also commits the other thread's first-party rule (steam-frame skill) and
the first-party options table in docs/streaming.md.

Reviewed by GPT-6 Astra (xhigh, read-only) over six rounds; all findings fixed.

# 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).

# Mac in the headset
Frame Control can show any Mac window, or a whole Mac screen, as its own panel
in the Steam Frame. You place each panel anywhere in the room with the SteamVR
dashboard. The laser clicks and drags, the thumbstick scrolls, and you type on
the Mac's own keyboard. Find it under **Tools → Mac in the headset** (macOS
only).
The confidence labels are the same as in [ssh.md](ssh.md).
## Why this design
First-party options come first, as the repo's rule asks, with the reason
each one was or wasn't chosen. The full list for every device is in
[streaming.md](streaming.md#first-party-options-and-why-they-do-or-dont-fit).
Checked 2026-09-28.
| Goal | First-party option | Chosen? | Why |
|---|---|---|---|
| One Mac screen in the headset | **Apple Screen Sharing** (VNC) → Remmina (Remmina 1.4.43 is already installed on this Frame) | Kept as the fallback (`panel-on-frame.sh mac-screen`) | It's the closest to first-party and needs nothing new. But VNC sends compressed tiles rather than video, so moving content is slow: noticeable lag even on a good 5 GHz link (**verified** 2026-09-27, see [streaming.md](streaming.md)), and the Mac's pointer isn't in the picture without a helper. It shows only whole screens |
| One Mac screen | **Steam Remote Play**, Mac as host (Valve) | For Mac games only; see [Steam's own streaming](#steams-own-streaming) | The Mac's and the Frame's Steam clients already find each other (**verified**). But Remote Play streams a game (the whole desktop only while the game is out of focus, untested from a Mac), never single windows, and a Mac can't host the Frame's VR streaming |
| One Mac screen | **AirPlay** (Apple) | No | Apple licenses AirPlay receivers only to TV and speaker makers, and nothing official runs on Linux. UxPlay is an unofficial receiver, and it mirrors a whole screen, not single windows |
| One Mac screen | **Sidecar / Mac Virtual Display** (Apple) | No | These work only with an iPad or Apple Vision Pro |
| **Each Mac window as its own panel** | None | – | No first-party way does this: Apple's per-app streaming is only for Vision Pro, and Valve's desktop streaming needs a Windows SteamVR host. So Frame Control does it itself |
| Mac keyboard and trackpad driving the headset | **Bluetooth HID** | No | macOS can't act as a Bluetooth keyboard or mouse. A real Bluetooth keyboard paired with the Frame still works |
| Mac keyboard and trackpad | **KDE Connect** (KDE) | No | The Frame has no `kdeconnectd` and it isn't on Flathub. Its Mac app has no keyboard or mouse sharing (**inferred**), and on Wayland it can only reach the desktop panel |
| Mac keyboard and trackpad | **xrdp** (Valve, Developer Mode) | No | It runs a separate Linux session that you view on the Mac. It isn't the headset's view, and it doesn't carry input the other way |
What that leaves is our own stream: nothing to install on the Mac or the
Frame, and whole screens or single windows. Here the Mac's own keyboard and
trackpad need no forwarding, because the windows are still on the Mac. The
laser is the only input that has to be sent back.
Other routes that were compared:
| Option | One screen | Each window | Speed | Verdict |
|---|---|---|---|---|
| Sunshine → Moonlight | ✓ | – | Good | Sunshine's macOS support is still experimental ([discussion #777](https://github.com/orgs/LizardByte/discussions/777)), and it captures whole screens only |
| Virtual Desktop, Immersed | – | – | – | No Frame client as of September 2026 |
| **Frame Control's own stream** | ✓ | ✓ | Hardware H.264, sending only changed frames | **Built** |
To type into VR surfaces other than these panels (SteamVR's dashboard,
games), the Frame supports a uinput keyboard and mouse without sudo
(verified 2026-09-27: `steamos` is in `input`, and `/dev/uinput` is
`root:input 660`). That's a separate feature, not part of this one.
## Steam's own streaming
The Frame is built around Steam streaming, so this was checked first
(2026-09-28). It fits Mac games, not Mac windows.
- **VR streaming from the Mac: no.** The Frame streams VR from a PC running
SteamVR ("Steam Link" with foveated streaming). SteamVR dropped macOS in
2020, and Valve lists PCs, laptops, Steam Deck and Steam Machine as
hosts, never a Mac (**documented**:
[UploadVR](https://www.uploadvr.com/steamvr-drops-mac-support/),
[Road to VR](https://roadtovr.com/steam-frame-game-certification-specs/)).
- **Flat Remote Play from the Mac: probably, for Steam games.**
- Steam on this Mac has streaming on, and the two Steam clients already
see each other. The Frame's `remote_connections.txt` shows it
connecting directly to "Alexs-MacBook-Pro-7" at 192.168.1.211:27036,
and the Mac's shows the Frame connecting over Wi-Fi and over the USB-C
link (**verified** in both clients' logs).
- Whether a stream then starts, and how a flat game looks in the headset
(reviews describe a theater screen), is **not tested yet**. The Frame's
Steam was crash-looping during this session (below).
- Mac-hosted Remote Play has a long-standing report of the stream
closing as the game loads
([Steam forum](https://steamcommunity.com/groups/homestream/discussions/1/574921459914429988/),
**reported**).
- **The Mac desktop through Steam: untested; single windows: no.** Valve
says Remote Play shows the host's desktop when the game loses focus
([Steam Remote Play FAQ](https://help.steampowered.com/en/faqs/view/0689-74B8-92AC-10F2),
**documented**), so a whole Mac screen may be reachable by starting a
game, then switching away from it. Nobody has tried that from a Mac
host. It would still be one screen in one panel: Remote Play has
nothing like one panel per Mac window, so Frame Control's own stream
stays the way to see separate windows.
- **Steam has a "stream desktop" call, and it pairs with a Mac
(verified 2026-09-28).** In the Remote Play device list, the Frame's
Steam UI calls `SteamClient.RemotePlay.StartDesktopStream(<client id>)`
for a connected device. Called over CDP with the Mac's client ID, it made
the Mac's Steam show "Authorize Device" and ask for a 4-digit code shown
on the Frame. Once the code was entered, the Mac logged
`k_ERemoteDeviceAuthorizationSuccess`. No stream started in that attempt,
and a second attempt, now that the device is authorized, is the next
test. If it streams the Mac's desktop, that's a whole-screen option built
into Steam: one panel, Valve's encoder and transport. It still wouldn't
give each window its own panel.
- **What Steam's work did give us: the USB-C link.** Plugged into the Mac,
the Frame appears as a network port called "Steam Frame". Steam's Remote
Play discovery uses it, and so does Frame Control's stream now (see
"USB-C, when it's plugged in" below).
Next steps, once Steam on the Frame is healthy:
1. Call `StartDesktopStream` again now that the Frame is authorized, and
compare its latency and sharpness with Frame Control's stream of the same
screen.
2. Stream the one Mac game installed here (Fortune Mill) from the Frame's
library, over Wi-Fi and over USB-C.
3. Record whether it starts, how it's shown, and its latency. Steam's
streaming overlay shows this; our benchmark can't measure it.
4. While streaming, switch away from the game on the Mac, and see whether
the Mac's desktop appears in the headset, and whether its keyboard and
pointer work.
5. If it works, Frame Control's Games page could offer "Stream from the
Mac" for Mac-installed games.
## How it works
```
Mac Frame
ScreenCaptureKit (one window or display)
→ VideoToolbox H.264 (hardware, low-latency,
no B-frames)
→ frame-mac-view, 127.0.0.1 ──ssh -R──→ 127.0.0.1:479xx
→ Chromium app window per stream
(WebCodecs decode), on gamescope's
X display, tagged STEAM_GAME
→ its own SteamVR panel
← CGEvent (clicks, drags, wheel, keys) ←──── pointer, wheel and key events
```
- **The agent** is `mac/bin/frame-mac-view`, built from `mac/frame-mac-view`
(Swift, no dependencies; `build.sh`). Frame Control's server starts it on
first use and stops it on quit.
- It captures with ScreenCaptureKit, which sends frames only when something
changes, so idle windows cost nothing.
- It encodes in hardware with VideoToolbox's low-latency rate control (plain
real-time mode where that's unavailable).
- While anyone is watching, it keeps the Mac's display awake. A sleeping
display isn't drawn, so there would be nothing to capture.
- **The link** is an `ssh -R` tunnel on its own connection. It's encrypted and
works anywhere `ssh frame` works, Tailscale included, with no firewall
changes on the Mac. If the headset sleeps or the network drops, Frame
Control reopens the tunnel on the same port, and open viewers reconnect by
themselves.
- **USB-C, when it's plugged in.** Connected to the Mac by cable, the Frame
is also a USB network device: macOS lists a network port called "Steam
Frame", and the Frame's `usb0` answers in under 1 ms. Frame Control
checks for it each time it opens the tunnel and uses it when it's there,
with the Frame's usual SSH host key. Otherwise it uses the normal path.
`FRAME_MACVIEW_USB=0` turns this off. **Verified** 2026-09-28, in two
interleaved pairs of runs:
| | USB-C | Wi-Fi (Tailscale) |
|---|---|---|
| test: content p50 / p95 | 6.9–7.3 / 8.4–8.8 ms | 9.8–10.1 / 12.1–12.3 ms |
| test: click to drawn p50 | 16.6–16.9 ms | 26.4–27.8 ms |
| scroll: content p95 | 23.0–23.5 ms | 31.4–36.9 ms |
| scroll: late frames | 3.2–3.3% | 4.7–7.0% |
(`bench/results/2026-09-28-*-usb1.json`, `-usb2`, `-wifi1`, `-wifi2`.)
- **Access.**
- Frame Control's own key never leaves the Mac.
- Each viewer is opened with a **single-use ticket**. It's tied to one
window or display and expires after a minute. It's spent as soon as the
viewer confirms it has received its reconnect key. Until then, a retry
gets the same key, so a connection lost at that moment doesn't strand
the viewer. Stop revokes tickets that haven't been used yet.
- After that, the viewer holds a reconnect key for that one source, in
memory only. **Stop** revokes it.
- Remaining risk: a program running as `steamos` on the Frame could read a
ticket from Chromium's command line in the first second or so and use it
first. That gets it the one source being opened, not the Mac, and the
real viewer would then fail to connect. Android apps in Lepton run in
their own podman container, so they shouldn't see the Frame's process
list (inferred, not checked).
- **The viewer** is `ui/mac-view.html`, served by the agent. It opens on the
Frame as a Chromium app window, preferring Chromium XR (`~/chromium-xr`,
built with H.264) over Flathub Chromium.
- The page puts `[fcNNNNN]` in its title. The launcher finds the window by
that tag and sets `STEAM_GAME` to a stable id per source, which gives it
its own panel (see [panels.md](panels.md)). The same Mac window gets the
same panel id each time.
- It decodes with WebCodecs. If it falls behind, it skips to the next
keyframe instead of showing old frames late.
- It falls back to JPEG stills (**Compatible** quality) where H.264 isn't
available.
- **Flow control.** The agent never lets frames queue up anywhere on the
way. It skips capture frames *before* encoding, so no reference frame goes
missing, and it lowers the bitrate, then the frame rate, then the size, to
fit the link (see [Adapting to the network](#adapting-to-the-network)).
- **Input.**
- A click on a window's panel brings that Mac window to the front
(Accessibility API), then clicks at the same point. Double clicks, right
clicks, drags and the wheel work too.
- Keys typed into the panel are sent as Mac key codes. Any keys or buttons
still held down are released if the viewer loses focus or disconnects, or
when the stream stops. Characters the key
table doesn't know, such as those from other keyboard layouts, are typed
as text.
- The Mac's own keyboard and trackpad keep working as normal. Click a panel
with the laser, then type on the Mac.
## Permissions (Mac)
- **Screen Recording**, to see windows. Without it, the card asks for it.
- **Accessibility**, so input from the headset reaches the Mac. Without it the
stream still works, and the viewer says clicks won't go through.
Both are granted to Frame Control. After granting, press **Refresh**, which
restarts the helper so it picks them up. The app is ad-hoc signed, so macOS
may ask again after an update.
## Quality settings
| Setting | Long side | fps | Codec | Use |
|---|---|---|---|---|
| Sharp | 2560 | 60 | H.264, ~0.14 bits/pixel | Text-heavy windows on a strong link |
| Balanced (default) | 1920 | 60 | H.264, ~0.1 bits/pixel | Most things |
| Light | 1280 | 30 | H.264 | Weak Wi-Fi or Tailscale off the LAN |
| Compatible | 1280 | 20 | JPEG | A Frame browser without H.264 |
## Measuring
Every frame carries a sequence number, and the agent records its journey on
the Mac's clock (`Sources/Stats.swift`):
| Stage | From → to |
|---|---|
| capture | the Mac composited it (ScreenCaptureKit's display time) → the agent got it |
| queue, encode | → encoding started → the encoder finished |
| network | → the viewer received it |
| decode, draw | → WebCodecs decoded it → it was drawn on the page's canvas |
| present | → the page's next animation frame |
- **Clock sync.** The viewer syncs its clock to the Mac's the way NTP does:
it pings over the stream's own WebSocket and keeps the sample with the
shortest round trip. It then reports, in Mac time, when each frame arrived
(right away, so the agent can pace itself) and when it was decoded and
drawn (in batches every 250 ms).
- **Input.** The first frame captured after a click or key carries that
event's id. So input latency is the viewer's event → injected on the Mac →
the first frame after it → drawn in the headset.
- **Where to see it.**
- `GET /stats` (key required) returns every frame and input record.
- `/status` includes a two-second summary, which Frame Control's card
shows next to each live stream.
- In the headset, add `?stats=1` to the viewer or press
Ctrl+Alt+Shift+S for an overlay.
- **The benchmark.** `scripts/macview-bench.py` runs fixed scenarios on the
real Frame, from the Mac, with nobody wearing the headset:
- **test** is the moving test pattern.
- **scroll** is a Chrome page on its own display scrolling at 240 pt/s,
which gives about 9 Mbit/s of real 1920×1290 video.
- **type** types into a Chrome text box, first fast and then with pauses.
It writes `bench/results/<date>-<commit>-<label>.json`, compares two
results, and runs interleaved A/B tests between agent settings (`ab`).
Wi-Fi changes from minute to minute, so single runs at different times
aren't comparable. Throttled links come from a shaping relay on the Mac,
which needs no sudo (`--net 50@0,3@8,50@16` means 50 Mbit/s, then 3 from
8 s, then 50 from 16 s).
- **What's graded.** "Content" runs from when the Mac composited a frame
(or when ScreenCaptureKit delivered it, if that was earlier) to when it was
drawn in the viewer. The Frame's compositor adds its own delay after that.
That part is reported, but not graded: an unworn Frame throttles panels to
about 36 fps after a few seconds, and to 15 fps in standby, whatever they
draw. This was **verified** with a local canvas page that ran on the Frame
with no network involved (`bench/pages/present.html`). The compositor's
share needs a run with the headset worn.
Targets: content p50 ≤ 25 ms (p95 ≤ 40), click to photon p50 ≤ 50 ms
(p95 ≤ 70), 60 fps with ≤ 1% late frames, no stall over 100 ms, and adapting
to a new link rate within 1 s.
Baseline on 2026-09-28 (**verified**, home Wi-Fi, Tailscale, Balanced,
`bench/results/2026-09-28-a3c6e5c-dirty-baseline-fixed.json`; ms p50/p95):
| Scenario | Content | Input to drawn | fps drawn | Notes |
|---|---|---|---|---|
| test (1280×720) | 9.9 | 28.8 / 39.0 | 59 | encode 4.0, network 4.0, decode 1.3 |
| scroll (1920×1290) | 14.7 | – | 50.4 | encode 6.7, decode 6.4 (software), 9.4 Mbit/s, 16% late |
| type (1920×1290) | 16.7 | 51.2 / 73.2 | – | most of the input time is the Mac app reacting |
After this work, with the controller on (**verified**, same setup,
`bench/results/2026-09-28-9e4dcdd-final.json`; ms p50/p95). Content is
now measured from the earlier of display time and delivery, which adds
about 5 ms to scroll compared with the baseline's way of measuring:
| Scenario | Content | Input to drawn | fps drawn | Grades |
|---|---|---|---|---|
| test | 10.5 / 16.7 | 29.6 / 36.3 | 60 | all within target |
| scroll | 19.8 / 27.4 | – | 55.9 | fps, late frames (4.8%) and worst gap (222 ms) only "acceptable": Wi-Fi stalls (the Mac captured 57 fps in this run; earlier runs got 46–53 from virtual displays) |
| type | 15.0 / 21.4 | 43.0 / 60.5 | – | all within target |
Of the targets, click to photon is met without the Frame's compositor (the
headset has to be worn to measure its share), and so is content latency.
The frame-rate and no-stall targets aren't yet met while scrolling.
**Worn** (**verified** 2026-09-28 22:00, `vrcmd --stats` activity level 1,
home Wi-Fi over Tailscale, `bench/results/2026-09-28-39afb23-worn.json`;
ms p50/p95):
| Scenario | Content | Input to drawn | fps drawn | What happened |
|---|---|---|---|---|
| test | 10.8 / 15.3 | 25.7 / 34.4 | 58 | as unworn |
| scroll | 22.2 / 141 | – | 37.7 | Wi-Fi queued 56–364 ms and held frames for 220–270 ms; the controller went to 2.6 Mbit/s and 45 fps |
| type | 13.5 / 24.3 | 56.8 / 106 | – | slower replies than unworn (43 / 60) |
The Frame's CPU wasn't the limit: about 27% in total, and the viewer took
45% of one core. The link to a headset on someone's head is much rougher
than to one lying still. The adaptation keeps latency bounded there, but
the frame rate drops. The USB-C cable avoids Wi-Fi entirely. Frames
actually shown were still about 39 fps for the test pattern while worn, so
the unworn throttling isn't the whole story. The cause is **unknown**.
What was learned (all **verified**, unless marked):
- The biggest costs are encoding (4–7 ms), network (4–6 ms), and decoding
on the Frame. Chromium XR on the Frame decodes H.264 in **software**.
- Wi-Fi alone stalls for 240–580 ms now and then, over Tailscale and over
the LAN alike. Over the LAN (`--host 192.168.1.237`) latency was no
better, but the Frame used about 8% less CPU, because tailscaled runs in
userspace there.
- With no controller, a link that slows down queues without limit. In one
run, frames arrived 1.9 s late, and at worst 9.4 s late.
- Tried, and no help, so not kept: VideoToolbox options (require hardware,
no frame delay, prioritise speed, a hard data-rate cap), Chromium flags
(`--disable-gpu-vsync`, `--disable-frame-rate-limit`,
`--use-angle=vulkan`), and a 120 Hz virtual display.
- Inconclusive, so off by default: keeping the Frame's Wi-Fi awake during
typing (`FRAME_MAC_VIEW_WARM=40`, a tiny message every 40 ms for 5 s
after input). Over three interleaved runs each, input p50 went 44 → 47 ms
and p95 92 → 71 ms, and the ranges overlapped widely
(`…-ab-keepwarm.json`). In that run, and in the baseline's typing, the
harness typed spaces as "+" (a URL-encoding bug, since fixed), so they
went through the text path rather than as space keys.
- Pointer moves now go out on an 8 ms timer, not on the page's next
animation frame, which an unworn Frame slows to 15–36 Hz. This is
**inferred** to help dragging; the benchmark has no drag scenario yet.
- Kept: the encoder's timestamps never jump more than two frame intervals.
Before this, the first frame after a pause got a quarter of a second's
bit budget, and one P-frame reached 204 KB.
## Adapting to the network
`Sources/Controller.swift`, per stream, latency first:
- **The gate.** The viewer acknowledges every frame as it arrives. A new
frame is sent only while the oldest unacknowledged one is younger than
the path's usual round trip, plus one frame interval, plus room for this
link's normal jitter (1.5 times its recent spread, 25–80 ms). So frames
never queue in SSH, TCP or the Wi-Fi driver. While the link is stuck, the
newest picture waits and goes out as soon as it moves.
- **The bitrate.** The link counts as congested when, for two checks in a
row (100 ms apart), round trips grow by more than 40 ms while the stream
uses much of its budget, or the gate holds frames back, or a frame is
stuck for 100 ms. Then the bitrate drops to a bit under what actually got
through: at least a fifth off, and at most half. Once the link has been
clear for a second, it rises by 10% steps, never above the quality
setting's bitrate.
- **The tier.** When the bitrate stays low, and the stream is really
limited by the link rather than having little to send, it steps down:
60 → 45 → 30 fps, then 75%, then 50% of the pixels. It goes straight to
the tier the bitrate supports after half a second, and steps back up one
tier at a time after two seconds with room to spare.
- `FRAME_MAC_VIEW_ADAPT=0` turns it off, for comparison.
Measured on the real Frame, 2026-09-28 (**verified**; interleaved A/B, off
versus on, medians of the runs, ms):
| Link | Scenario | Content p95, off → on | fps drawn, off → on | Result file |
|---|---|---|---|---|
| Clean Wi-Fi (3 runs each) | scroll | 32.3 → 33.6 | 57 → 56.2 | `…-ab-adapt-clean2.json` |
| Clean Wi-Fi | test | 15 → 14.2 | 60 → 59.7 | same |
| 50 → 3 → 50 Mbit/s at 8 s and 16 s (2 runs each) | scroll | **4670 → 72** | 45 → 42 | `…-ab-adapt-step3.json` |
| 50 → 3 → 50 Mbit/s | test | 66 → 16 | 60 → 60 | same |
- **Clean link.** On a clean link it costs nothing measurable. An earlier
version with a fixed gate slack lost 9 fps to Wi-Fi jitter while
scrolling (47 → 38 fps), and that's why the slack now follows the link's
jitter.
- **Throttled link.** Without the controller, frames queued for up to 5.6 s
and never caught up while the link was slow (p95 1.8–5.6 s, second by
second). With it, in the two runs:
| | Run 1 | Run 2 |
|---|---|---|
| Worst second's p95 just after the drop | 219 ms | 428 ms |
| p95 back under 100 ms for 3 s in a row | after 1 s | after 4 s |
| Stepped down to 1440 px at 30 fps | 1.8 s after the drop | 3.5 s after |
| p95 per second after that, on the 3 Mbit/s link | 55–94 ms | 60–148 ms |
Sending one frame takes about 27 ms on that link by itself. After the
link recovered, the stream was back at full size and 60 fps in about
7.5 s. It steps up one tier every two seconds, on purpose, so it doesn't
bounce. The 1 s adaptation target was met in one run of two.
- **A hiccup on a small stream.** In one clean run, a Wi-Fi hiccup made an
earlier version halve the test pattern's bitrate five times and drop it
to half size. That cut couldn't help: the stream only sends
0.47 Mbit/s. Now the controller estimates what a stream wants (captures
per second × average frame size). While a stream wants about half its
budget or less, no cut takes it below twice what it wants, so it doesn't change
tier.
## Checked so far (2026-09-28)
- **Mac (checked by hand, macOS 26.5.2).**
- The agent builds, and lists windows and displays.
- In a browser, the test pattern decoded at about 60 fps (H.264) and 30 fps
(JPEG, about 22 Mbps).
- A click in the viewer arrived at the same point in the source.
- `pmset -g assertions` showed the display-awake assertion only while a
stream was being watched.
- **Automated** (`tests/test_macview.py`, on CI's macOS runner): the agent
builds (a build failure fails the job).
- `/ping` and the page are open; everything else needs the key.
- Tickets work once and only for their own source, and Stop revokes
reconnect keys.
- A WebSocket frame claiming 2^63 bytes closes that socket, and the agent
keeps running.
- A stream sends an SPS-led H.264 keyframe, and sends another when asked.
- Stop ends the stream on the Mac even if the viewer ignores it.
- The test doesn't decode video, time it, or check where clicks land.
- **Linux aarch64 (verified in a stand-in, not on the Frame).** In an Arch
Linux ARM container with sshd, Xvfb as `:0` and Chromium 153:
- The real `show` path worked in 1–2.3 s: tunnel, ticket, launcher,
window found and tagged `STEAM_GAME`.
- Frame Control's key didn't appear anywhere in the stand-in's process
list.
- After the tunnel was killed, it came back on the same port within 4 s,
and the viewer reconnected by itself.
- Chromium decoded the stream in software with the GPU off.
- Stop closed the window, and Chromium exited.
- This test found and fixed a bug: in a C locale, `xwininfo` can't print a
title with non-ASCII characters, so the launcher reads `_NET_WM_NAME`
with `xprop`.
- **On the Frame (verified 2026-09-28, SteamOS build 20260925.6191901,
from the Mac, nobody wearing the headset).** Frame Control's **Show** with
the test pattern:
- The panel was ready in 1.45 s. SteamVR logged `[Overlays] Created:
valve.steam.desktopgame.2001639889` (in `vrwebhelper_systemui.txt`).
- The window was tagged `STEAM_GAME`, and gamescope sized it to 1920×1080
although 1280×720 was asked for.
- Chromium XR decoded it live at about 60 fps: the frame counter advanced
62 in 1.04 s.
- Over home Wi-Fi, the frames in the viewer window had been drawn on the
Mac about 11–17 ms earlier, plus `xwd`'s own time. That's measured
against the two clocks, which were 37–39 ms apart (±4 ms, measured over
one SSH session). SteamVR's compositor and the display come on top.
- Clicks and keys injected with XTest into gamescope's Xwayland didn't
reach the page. That's inconclusive, not a failure: XTest on gamescope
isn't how real input arrives. The laser should arrive as a left mouse
button and the thumbstick as a wheel, because the window has an app id
(from gamescope's source; see [panels.md](panels.md)).
- **Not yet checked:**
- Clicking, dragging and scrolling with the laser while wearing the
headset.
- Real window capture and input on a Mac with both permissions granted.
- Keys from SteamVR's on-screen keyboard.
- Whether Flathub Chromium has H.264. Chromium XR is used when it's
installed, as it is on this Frame.
- Latency with real, busy windows at Sharp.
- A benchmark run while wearing the headset. Only then does the Frame show
panels at full rate, so only then can the compositor's share of the
latency, and the frame rate you actually see, be measured.
## Limits
- Only windows on the Mac's current desktop (Space) are listed, and
minimised windows can't be captured.
- A window's panel shows only that window. Its menus and sheets are separate
windows on the Mac, so open them from the Mac or use **Whole screen**.
- Keys go to whichever Mac window is in front. Clicking a panel brings its
window to the front first.
- Ctrl stays Ctrl. On the Mac, copy is ⌘C, so use Meta+C on a keyboard paired
with the Frame.

# Real separation of Mac windows in the headset
Research and experiments on 2026-09-28 (macOS 26.5.2, Apple M5 Pro), for
making each streamed Mac window truly independent. Builds on
[mac-in-headset.md](mac-in-headset.md). Labels: **verified** (tried here),
**documented**, **source** (read in someone's code) or **reported**.
## What "separate" lacks today
Today each window is captured on its own
(`SCContentFilter(desktopIndependentWindow:)`), but it still lives on the
Mac's one desktop:
- **Clicks.** A click has to raise the window first, so it reorders the
Mac's windows, steals focus and moves the real cursor.
- **Child windows.** A window's menus, popovers, sheets and tooltips are
separate windows, so they aren't in its panel. Apple documents that the
single-window filter leaves them out.
- **Size.** A panel's size is tied to the window's size on the Mac screen.
- **Hidden windows.** Minimised windows, and windows on other Spaces, can't
be shown live.
## How the Mac draws, and where pixels can be read
Apps draw with Core Animation into IOSurfaces. WindowServer's compositor
stacks every window onto each display, including virtual ones, and sends
the result to the screen. Pixels can be read at three points:
| Where | How | Gets | Doesn't get |
|---|---|---|---|
| One window's content | ScreenCaptureKit `desktopIndependentWindow` (public, what we use) | Live, zero-copy, even when covered by other windows (**documented**) | Menus, popovers, sheets. It pauses while the window is minimised (**reported**) |
| One window plus its children | `SCStreamConfiguration.includeChildWindows` (macOS 14.2+, **reported**) | Menus, popovers and sheets attached to the window | Anything the app puts outside the window's bounds |
| A whole display | ScreenCaptureKit display filter, with apps or windows included or excluded | Everything on that display, cursor included | Only what's on that display |
| A snapshot of any window | Private `CGSHWCaptureWindowList`, which AltTab uses for minimised windows and other Spaces (**source**: `alt-tab-macos` `PrivateApis.swift`) | Minimised windows and other Spaces | It's one still image, not a live stream |
| Another app's layer tree | Private `CALayerHost` with a context id | A live, zero-copy picture | It only works when the other app cooperates, so it's no good for arbitrary windows (**reported**) |
`CGWindowListCreateImage` and `CGDisplayStream` are obsolete in the macOS 15
SDK (**reported** by MacPorts and JUCE). Nothing reads another app's pixels
without the Screen Recording permission.
## The idea: each window gets its own virtual display
A virtual display (the private `CGVirtualDisplay`, as used by BetterDisplay,
DeskPad and quest-display) is a compositor target with no physical screen.
Put one streamed window alone on its own virtual display, sized to its
panel, and capture the whole display:
- **Nothing can overlap it.** A plain click at that point always lands on
that window, so input doesn't need raising or background-event tricks.
- **Menus, sheets, popovers, tooltips and context menus appear on the same
display, so they're in the panel.** With "Displays have separate Spaces"
on (it is on this Mac), each display also has its own menu bar, so the
app's menu bar can be part of the panel.
- **The panel's size is the display's size,** in HiDPI. Resizing the panel
means changing the display mode and resizing the window to fill it
(Accessibility API).
- **Minimised windows and other Spaces stop being a problem,** because
streamed windows live on their own displays.
- **The cursor goes where the laser points.** That display's panel is the
one being used, much as Vision Pro's Mac Virtual Display works. Keys from
the Mac's keyboard go to the window last clicked.
### Verified here (no permission needed)
- **Creating one.** It needs no permission or entitlement. 1920×1080 HiDPI
gives a 3840×2160-pixel, 60 Hz display, placed next to the built-in
screen, and `NSScreen.screensHaveSeparateSpaces` was true.
- **Many at once.** 16 were created at once with no error.
- **Placement.** `CGConfigureDisplayOrigin` far away failed with error
1014: macOS keeps displays edge to edge. Disabling one with the private
`CGSConfigureDisplayEnabled` from a command-line tool also failed with 1014.
- **Removal is deferred while the physical screen sleeps.** With the
built-in display asleep, virtual displays were not removed when released,
or when their process exited, even from their own `.app`. A second display
with the same vendor, product and serial couldn't be created. All of them
disappeared as soon as the screen woke (`caffeinate -u`). The helper must
therefore:
- keep a fixed pool of displays and reuse them rather than create new ones;
- keep the screen awake while they exist, which it already does while
streaming.
### Built: "Give each window its own display"
Frame Control's helper now does this (`mac/frame-mac-view/Sources/Separate.swift`),
and it's the default in the Tools card. Streams of this kind are named
`separate:<window id>`.
- For each window shown, it creates a HiDPI virtual display. The display is
sized to the window plus a menu bar, with a fresh serial each time, so a
display left over while the screen slept can't block a new one.
- The window is moved onto the display and resized to fill it (Accessibility
API), and the whole display is captured.
- On **Stop** the window goes back where it was, and the display is released.
- Plain per-window capture is still there: untick "Give each window its own
display". Separate mode needs Accessibility (to move the window), and
without it, Show says so rather than quietly falling back.
Verified 2026-09-28 (macOS 26.5.2, M5 Pro), using a TextEdit test document
and the benchmark's Chrome windows:
- **Separation works.** The window moved onto its own display and streamed,
with its first frames in 3.8 s. The display showed TextEdit's own menu bar.
- **Child windows come along.** A context menu and the Page Setup sheet
opened on the same display and were in the capture.
- **Input.** Typing through the stream reached the window. The benchmark's
typing scenario does this on every run.
- **Stop.** Stop put the window back at exactly its old size (656×422), and
the display was removed.
- **The helper must run a real Cocoa event loop.** Earlier, it ran only a
`RunLoop`. With that, AppKit never learned about new displays:
- `NSScreen.screens` never listed them, so placing the window always waited
3 s and then gave up;
- the display's HiDPI mode never applied, so windows were captured at 1×
(1280×860 instead of 1920×1290 pixels) and text was soft.
Running `NSApplication` (with no Dock icon) fixed both. The screen now
appears within 100 ms, and captures are at 2× (**verified** in
`bench/results/*-baseline.json` against `*-baseline-fixed.json`).
- **Frame rate.** Chrome drew at 60–61 fps on the virtual display, but
ScreenCaptureKit delivered only about 46–53 fps from it, whereas the
built-in ProMotion screen gave 121 fps (**verified**). Neither a 120 Hz
virtual display (`FRAME_MAC_VIEW_VD_HZ=120`) nor a looser
`minimumFrameInterval` changed that. Cause unknown.
- **Windows that keep their own size** (Calculator, 230×408). The window
moved and streamed, but stayed small in the display's corner, so the panel
was mostly wallpaper. Now only that corner is captured
(`SCStreamConfiguration.sourceRect`): the menu bar and the window, at least
480×360 points so menus fit. Clicks map to the cropped area. The first
frame arrived in 0.6–1.1 s, and on Stop the window went back and the
display was removed. A display's menu bar names the active app, so it
shows the window's own menus only once the panel has been clicked.
- **Several windows at once** (on the Mac, with a local stand-in viewer that
acknowledges frames). Three and four Chrome windows, each scrolling on its
own display at 1920×1290 pixels, streamed at 53–56 fps and about
9 Mbit/s each. The helper used 20% (three) or 24% (four) of one CPU core.
The hardware encoder is shared: its time per frame went from 6.7 ms for
one stream to 7–15 ms for three and 11–25 ms for four, so each extra
moving window adds latency to the others. Once in four runs, before a fix,
one window left its display when several displays appeared at the same
moment, and its stream stopped: nothing on that display was changing any
more. The helper now checks every second and puts the window back. Three
further runs with four windows were clean, and every display was gone
afterwards (checked with `CGGetOnlineDisplayList`).
- **Quitting.** On SIGTERM, or when Frame Control goes away, the helper ends
every stream first, so windows go back before their displays disappear.
Verified: a 900×600 window was back at 900×600 after SIGTERM. Closing a
viewer 0.05–1.5 s into startup left the window at its old size and no
extra display.
- **A consent prompt.** macOS 26 asks whether to let ScreenCaptureKit apps
"bypass the system private window picker". The prompt appeared *on the
virtual display*, so it would show up inside the headset panel. Allow it
once on the Mac.
### Still to check
1. That a context menu opens over the text being clicked, not just somewhere
on the display. This needs a retest after the consent prompt above is
allowed.
2. Stage Manager, which is reported to undo Accessibility resizes.
3. Where the Dock and the cursor go on a virtual display.
4. Closing the lid with virtual displays attached (clamshell).
5. Many moving windows at once in the headset: whether to lower the bitrate
or frame rate of panels you aren't using, so the one you are using keeps
the encoder to itself.
6. All of it in the headset, with the laser.
## Input without disturbing the Mac (a finer option)
For windows that stay on the Mac's own screen, input can go to a window
behind others without raising it:
- **Background click.** `CGEventPostToPid` with the CGEvent fields 91 and
92, which say which window a click is for (`kCGMouseEventWindowUnderMousePointer`
and `...ThatCanHandleThisEvent`), plus a window-relative location
(**reported**, reverse-engineered, needs testing).
- **Focus without raise.** yabai makes a window key without raising it by
posting event records with the private `SLPSPostEventRecordTo` (**source**:
`yabai/src/window_manager.c`).
- **Known failures.**
- Chromium and Electron ignore background clicks unless they're built
with the 2026 `acceptsFirstMouse` fix (electron/electron#54493).
- Games and canvas apps often need real activation.
- Password fields (Secure Event Input) drop synthetic keys.
- IME composition, as for Chinese or Japanese input, isn't reliable.
With a virtual display per window, most of this isn't needed. It's worth
having for hovering over one panel while typing in another.
## Encoding and transport
- **Codec.** Keep H.264 4:2:0. Apple's High Performance Screen Sharing uses
4:4:4 over two virtual displays (**documented**), but the Frame's Chromium
decodes H.264 in software, and no 4:4:4 decode path is confirmed there.
- **Sharper static text.** When a panel has been still for a moment, send a
high-quality refresh, either a keyframe at low quantisation or a lossless
WebP overlay, so static text is sharp. Moving content stays as video.
- **Transport.** Keep WebSocket over SSH for now, as it works everywhere.
WebRTC (UDP, congestion control) is the proven step up for Wi-Fi.
WebTransport over QUIC is promising, but its server side on macOS is
unverified.

# 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.

## 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.
- **Not yet tested:** typing and clicking as seen in the headset, and 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.
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 |
|---|---|---|---|
| **A uinput keyboard and mouse in Frame Control's server** | ✓ | ✓ | **Recommended.** The server opens `/dev/uinput` with `ctypes` (standard library only) and the page sends key and pointer events through the tunnel it already has. On the phone: a trackpad area (drag to move, tap to click, two fingers to scroll) and the iOS keyboard for typing. 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.

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 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:

"Work" shall mean the work of authorship, whether in Source or Object form,
made available under the License, as indicated by a copyright notice that
is included in or attached to the work (an example is provided in the Appendix
below).
"Derivative Works" shall mean any work, whether in Source or Object form,
that is based on (or derived from) the Work and for which the editorial revisions,
annotations, elaborations, or other modifications represent, as a whole, an
original work of authorship. For the purposes of this License, Derivative
Works shall not include works that remain separable from, or merely link (or
bind by name) to the interfaces of, the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including the original version
of the Work and any modifications or additions to that Work or Derivative
Works thereof, that is intentionally submitted to Licensor for inclusion in
the Work by the copyright owner or by an individual or Legal Entity authorized
to submit on behalf of the copyright owner. For the purposes of this definition,
"submitted" means any form of electronic, verbal, or written communication
sent to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems, and
issue tracking systems that are managed by, or on behalf of, the Licensor

that is conspicuously marked or otherwise designated in writing by the copyright
owner as "Not a Contribution."
"Contributor" shall mean Licensor and any individual or Legal Entity on behalf
of whom a Contribution has been received by Licensor and subsequently incorporated
within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of this
License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
no-charge, royalty-free, irrevocable copyright license to reproduce, prepare
Derivative Works of, publicly display, publicly perform, sublicense, and distribute
the Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of this License,
each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
no-charge, royalty-free, irrevocable (except as stated in this section) patent
license to make, have made, use, offer to sell, sell, import, and otherwise
transfer the Work, where such license applies only to those patent claims
licensable by such Contributor that are necessarily infringed by their Contribution(s)
alone or by combination of their Contribution(s) with the Work to which such
Contribution(s) was submitted. If You institute patent litigation against
any entity (including a cross-claim or counterclaim in a lawsuit) alleging
that the Work or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses granted to You
under this License for that Work shall terminate as of the date such litigation
is filed.
4. Redistribution. You may reproduce and distribute copies of the Work or
Derivative Works thereof in any medium, with or without modifications, and
in Source or Object form, provided that You meet the following conditions:
(a) You must give any other recipients of the Work or Derivative Works a copy
of this License; and
(b) You must cause any modified files to carry prominent notices stating that
You changed the files; and
(c) You must retain, in the Source form of any Derivative Works that You distribute,
all copyright, patent, trademark, and attribution notices from the Source
form of the Work, excluding those notices that do not pertain to any part
of the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its distribution,
then any Derivative Works that You distribute must include a readable copy
of the attribution notices contained within such NOTICE file, excluding those
notices that do not pertain to any part of the Derivative Works, in at least
one of the following places: within a NOTICE text file distributed as part
of the Derivative Works; within the Source form or documentation, if provided
along with the Derivative Works; or, within a display generated by the Derivative
Works, if and wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and do not modify the
License. You may add Your own attribution notices within Derivative Works
that You distribute, alongside or as an addendum to the NOTICE text from the
Work, provided that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction,
or distribution of Your modifications, or for any such Derivative Works as
a whole, provided Your use, reproduction, and distribution of the Work otherwise
complies with the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise, any
Contribution intentionally submitted for inclusion in the Work by You to the
Licensor shall be under the terms and conditions of this License, without
any additional terms or conditions. Notwithstanding the above, nothing herein
shall supersede or modify the terms of any separate license agreement you
may have executed with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade names,
trademarks, service marks, or product names of the Licensor, except as required
for reasonable and customary use in describing the origin of the Work and
reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or agreed to
in writing, Licensor provides the Work (and each Contributor provides its
Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
KIND, either express or implied, including, without limitation, any warranties
or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR
A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness
of using or redistributing the Work and assume any risks associated with Your
exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory, whether
in tort (including negligence), contract, or otherwise, unless required by
applicable law (such as deliberate and grossly negligent acts) or agreed to
in writing, shall any Contributor be liable to You for damages, including
any direct, indirect, special, incidental, or consequential damages of any
character arising as a result of this License or out of the use or inability
to use the Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all other commercial
damages or losses), even if such Contributor has been advised of the possibility
of such damages.
9. Accepting Warranty or Additional Liability. While redistributing the Work
or Derivative Works thereof, You may choose to offer, and charge a fee for,
acceptance of support, warranty, indemnity, or other liability obligations
and/or rights consistent with this License. However, in accepting such obligations,
You may act only on Your own behalf and on Your sole responsibility, not on
behalf of any other Contributor, and only if You agree to indemnify, defend,
and hold each Contributor harmless for any liability incurred by, or claims
asserted against, such Contributor by reason of your accepting any such warranty
or additional liability. END OF TERMS AND CONDITIONS

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 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:

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:

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.>
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/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

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.

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.>

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;

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

NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR

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,

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

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 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'

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

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

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. >

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.

// Adapts each stream to its network, latency first. The viewer acknowledges

// long frames take to get through and how fast the link delivers them.
//
// - The gate: a new frame is sent only while the oldest unacknowledged one is
// younger than the path's usual round trip plus a little slack. So frames
// never queue up in SSH, TCP or the Wi-Fi driver; while the link is stuck
// the newest picture waits and goes out as soon as it moves again.
// - The bitrate: when frames start queueing (the round trip grows) or the
// gate has to hold frames back, it drops to a bit under what the link
// actually delivered; once things are clear it probes up again slowly, never
// above the quality setting's bitrate (the ceiling).
// - The tier: as the bitrate falls, fewer frames per second (60, 45, 30), then
// a smaller picture (75%, then 50% of the panel's pixels).
// See docs/mac-in-headset.md ("Adapting to the network"). Thread-safe.

"""Benchmark "Mac in the headset" on the real Frame, so every change to the
stream is judged by numbers (docs/mac-in-headset.md, "Measuring").
scripts/macview-bench.py run [--scenario test,scroll,type] [--net 8] [--label x]
scripts/macview-bench.py compare bench/results/A.json bench/results/B.json
scripts/macview-bench.py ab --arm off:FRAME_MAC_VIEW_ADAPT=0 --arm on: --repeat 3 --scenario scroll
`run` uses the lab agent (mac/frame-mac-view/lab.sh serve), which has
Screen Recording and Accessibility. It opens a viewer on the Frame the way
Frame Control does, drives a fixed scenario, and reads the agent's per-frame
records: when the Mac composited each frame, when it was encoded and sent,
and when the viewer received, decoded and drew it (the viewer's clock is
synced to the Mac's). "content" is Mac composited -> drawn in the viewer;
what the Frame's compositor adds after that is reported ("present",
"fps_shown") but not graded, because an unworn Frame throttles panels to
36 fps (15 in standby) after a few seconds whatever they draw. It writes a summary to bench/results/ and exits 1 if a
target is missed ("bad"), or if --baseline is given and a key number got
more than 10% worse.
Wi-Fi changes from minute to minute, so single runs taken at different times
can differ by more than a change does. `ab` restarts the lab agent with each
arm's settings (environment variables read by the agent), runs the arms
interleaved, and prints each metric's median and range per arm.
Nobody needs to wear the headset. The scroll and type scenarios open a
throwaway Chrome window (its own profile in /tmp) on the Mac.
Network conditions come from a relay on the Mac between the agent and the
tunnel, so they need no sudo:
--net 8 8 Mbit/s the whole run
--net 50@0,8@10,50@20 50 Mbit/s, 8 from 10 s, back to 50 from 20 s
--delay 30 30 ms more one-way delay
The relay holds at most --buffer ms of data at the current rate (default
250 ms, like a bloated Wi-Fi queue), then pushes back on the agent.
Stdlib only.

"""Keyboard and pointer for the Steam Frame. Frame Control's server runs this ON the Frame.
It speaks KDE Connect's LAN protocol (version 7, as in KDE Connect 24.02) to the
Frame's own kdeconnectd, as a phone would, and forwards remote-input events read
from stdin: one JSON object (or list of them) per line, each a KDE Connect
"mousepad" request body such as {"dx": 4, "dy": -2} or {"key": "hello"}.
KDE Connect does the typing and clicking.
KDE Connect isn't installed on the Frame. Frame Control ships Valve's build of it
for the Frame and the few libraries the Frame lacks (frame/kdeconnect); the server
copies them over the SSH connection and this unpacks them into
~/.local/share/frame-control/kdeconnect: no root, no internet, and SteamOS
updates leave it alone.
argv: client id, client name, the folder holding the packages, and a JSON list
of [file, sha256] naming them (see frame/kdeconnect/packages.json).
Status goes to stdout, one JSON object per line:
{"state": "installing" | "starting" | "pairing" | "ready" | "error" | "need-packages", ...}.
Standard library only: this runs on the Frame's own Python.

"""Mac in the headset: stream Mac windows or displays into the Steam Frame as
panels you can place anywhere, with the laser, wheel and keys driving the Mac.
Runs on the Mac, inside Frame Control's server. The pieces:
- mac/bin/frame-mac-view (Swift, built from mac/frame-mac-view): captures with
ScreenCaptureKit, encodes with VideoToolbox, serves ui/mac-view.html and one
WebSocket per stream on 127.0.0.1, and plays input back with CGEvent.
- An `ssh -R` tunnel, so the Frame reaches the agent on its own 127.0.0.1.
Every request carries a random token, so other programs on the Frame
(Android apps included) can't watch or drive the Mac.
- A Chromium app window on the Frame per stream, on gamescope's X display
with its own STEAM_GAME id, which makes it its own SteamVR panel (see
docs/panels.md). Chromium XR (~/chromium-xr) is preferred because it's
built with H.264; Flathub Chromium is the fallback.
Stdlib only. MacView gets a plain ssh argv for the tunnel (its own
connection) and the server's `run(remote, stdin=, timeout=)` for commands.
