|
|
# 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.
