# Install the hand recorder on a Frame that has Frametop (get.sh --experimental): bring the dev
# container's packages up to date, build hand tracking's camera broker and tracker (hands/build.sh:
# the first build fetches and builds ncnn, a few minutes) and the headset panel (hands/rec/build.sh),
# give ft-camd its capabilities (hands/run.sh caps: asks for the password, once per build), and add
# "Frametop Hand Recorder" to the app menu (for Frametop's desktop: it isn't tested from SteamVR's
# "Launch a program", which runs apps outside it; the standalone recorder is for that).
# It doesn't turn on Frametop's live hand tracking (that's hands/run.sh install, still deferred).
# Usage: hands/rec/install.sh            install or update
#        hands/rec/install.sh uninstall  remove the menu entry (recordings stay where they are)
