"""Cull bad and shunt queues, recommended once per day.
This script goes through the 'bad' and 'shunt' queue directories and,
if mm_cfg.BAD_SHUNT_STALE_AFTER is > 0, it removes all files more than
that many seconds old.
If mm_cfg.BAD_SHUNT_ARCHIVE_DIRECTORY is a writable directory, the old
files are moved there. Otherwise they are deleted.
Only regular files immediately subordinate to the 'bad' and 'shunt'
directories are processed. Anything else is skipped.
Usage: %(PROGRAM)s [options]
Options:
-h / --help
Print this message and exit.
