## remove-unused-sources
#
# April 2008, Jonathan Moore Liles
#
# Simple script to scan a compacted Non-DAW project and remove all
# unused sources from disk.
#
# USAGE:
#
# $ remove-unused-sources ~/audio/'The Best Song Ever'
#
# NOTES:
#
# This script will not ask for comfirmation! It will ruthlessly
# delete all unused sources! You have been warned.
