Kestrel — live camera wall and PTZ control for your NVR

Run it directly:

    ./kestrel

Nothing needs installing. The `lib/` directory next to the binary holds the
ffmpeg libraries it uses; keep the two together.

Optional, to add it to your application menu:

    ./install.sh

Configuration lives in ~/.config/kestrel/config.json (mode 0600). Passwords go
to the system keyring when one is available.

Check which build this is:

    ./kestrel --version
