# This simple script acts as a remote for pianobar[1]. Its primary
# purpose is to provide a simple way for multiple remotes to
# interact with a single instance of pianobar
#
# This is currently just being tested and by no means in deployable
# condition.

# TODO: add better default behavior so this doesn't break on machines
# other than my own.
# (1) parameterize 
#   DONE (a) udp port
#   DONE (b) fifo
#   DONE (c) config file
# (2) figure out default behavior for lack of config
#   (a) prompt user?
# (3) figure out default behavior if ctl is missing
#   DONE (a) mkfifo? (resolved: yes, mkfifo)
# (4) what are failsafe defaults for keybindings?
#   (a) make a config file?
# (5) create an install.sh that makes fifo and config?
# (6) embed event_cmd behavior into this script (somehow)
# (7) handle concurrency to fifo by acquiring lock? may be unnecessary
#     since fifo buffers anyway. could explore listener-side buffering
#     with locks
