# To use the file, save it somewhere in your $path. Then 'chmod 755 filename' to make it executable. 
# Type 'rehash'. Then you can start using it. Personally mine is named 'itunes', so to start playing 
# I use the command:
# itunes play
#If you just type "itunes" it will list the options. Currently the options are:
# status = Shows iTunes' status, current artist and track.
# play = Start playing iTunes.
# pause = Pause iTunes.
# next = Go to the next track.p
# rev = Go to the previous track.
# mute = Mute iTunes' volume.
# unmute = Unmute iTunes' volume.
# vol up = Increase iTunes' volume by 10%
# vol down = Increase iTunes' volume by 10%
# vol # = Set iTunes' volume to # [0-100]
# stop = Stop iTunes.
# quit = Quit iTunes.
