"""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.
