[Tutor] Robot Radio program

[Kirk Bailey]

Simulates an old time radio station. Place program files in the numbered 
folders, station identifications in the ID folder, commercials in the 
com folder. run from the command line.

directories under the program are: ID, Com, 1,2,3,4,5... ID contains 
station identifications. COM is commercial recordings. 1,2,3,4,5... each 
numbered directory contains mp3 files of a particular show.

# there are 2 directories under this one- com and id. There are also 
numbered folders which
# contain files of old broadcasts. The system only referrs to number 
name directories to play programs
# but is taken by the hand to ID or com to play station identifications 
or commercials respectively.
#
# To add a broadcast group of 'programs', just create a new numbered 
directory and load the program
# files into it- and that's it, the program adapts to it. DO NOT add any 
directories EXCEPT numbered
# broadcast library file directories. The only 2 exceptions are com and 
ID. com contains commercials.
# ID contains station identification blip, anywhere from 5 to 30 seconds 
long. You can make your own mp3
# files and place them here.
