# soundboard.py - A script to generate an HTML5 document that can act as a 
# soundboard for audio clips. Currently the script only generates one file and 
# has no stylesheet. For this to work use the following directory struture:
#
# .
# +-- _audio_clips1
# |   +-- audio_file1.wav
# |   +-- audio_file2.wav
# +-- _audio_clips2
# |   +-- audio_file1.wav
# +-- soundboard.py
#
# To run the script use the following: python soundboard.py > soundboard.html
