* at the start of the day, create a file with a list of rooms that you
  want to monitor for that day.  I've already created files based on the
  SCaLE schedules, named ROOMS.thu, ROOMS.fri, ROOMS.sat, and ROOMS.sun,
  so you can use those (but check to make sure that they are correct)
* cd /scratch/raspberrypi.acatcher
* ./provision_streamers.sh ROOM_FILE
* wait for another minute or so after that script completes (it reboots the
  pi's which take a while to boot) then run ./check.sh ROOM_FILE
  This will test to make sure it can get to all of the pi's, if any are
  listed as DOWN, wait and try again; if still DOWN, there is some other
  problem.
* ./start_streamers.sh ROOM_FILE
* ./start_watcher.sh
* a bunch of windows will open splattered all across the screen.  to fix
  this, open another terminal window, cd to the same directory as before,
  and type ./fix_windows.sh ROOM_FILE
* control the audio stream from the window labeled "CONTROL" (NOTE: this
  window MUST BE IN FOCUS, so i.e. click on it)  Each window is labeled
  with the room's name and a number/letter in brackets, that is the key
  you press to bring up that room's audio.
* when done for the day, hit q, this will close all windows.  Then run
  the script ./stop_streamers.sh ROOM_FILE
* optionally you can run ./reboot_streamers.sh ROOM_FILE
  to reboot all of the pi's so that they are in a known state.
