# Use this script to tidy up a directory tree after deleting files (e.g.
# when uninstalling MuseScore). The script takes as argument a path (or
# a space-delimited list of paths) to recently deleted files:
# e.g. "/usr/local/share/mscore-dev-2.1/manual/plugins/harmony.html"
# If the file still exists nothing happens. If it's parent directory is
# empty then that is deleted. The parent's parent is deleted if it is
# now empty, and so on until all empty parents in the path are deleted.
