Glance Image Cache Pruner

This is meant to be run as a periodic task, perhaps every half-hour.

import sys

from oslo_log import log as logging

# If ../glance/ exists, add ../ to Python search path, so that
# it will override what happens to be installed in /usr/(local/)lib/python...

if os.path.exists(os.path.join(possible_topdir, 'glance', '')):
    sys.path.insert(0, possible_topdir)
