+#
+# April 2008, Jonathan Moore Liles
+#
+# Simple script to scan a compacted Non-DAW session 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.
+#
