Koha/misc/cronjobs/cleanup_database.pl
J. David Bavousett eb849c690a Created database-tidying cron script
This little script establishes a framework for database cleanup on some regular
schedule.  Initial implementation provides for brute truncation of the sessions
table, and selective-by-age cleanup of the zebraqueue.
