+"""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.
