OpenFM Radio Controller

Usage: openfm [peripheral]

Opens an interactive controller for an attached OpenFM radio. The radio may be
directly beside the computer or connected through a wired modem. If more than
one radio is attached, pass the peripheral name to select one.

The dashboard shows the current ICY song title when a nearby player is listening
to the stream. Title changes are pushed to attached computers automatically.

Keyboard controls:
  P       Start playback
  S       Stop playback
  + / -   Change volume
  U       Set or clear the stream URL
  T       Set the radio display text
  C       Set the display color as RRGGBB
  R       Refresh the dashboard
  Q       Quit

The buttons are also clickable on computers with mouse input. A radio locked by
its owner can be inspected but cannot be changed from a computer.
