/*
 * Remove expired userrights from user_groups table and move them to former_user_groups.
 *
 * By default, this does not need to be run. The UserGroupManager service naturally
 * takes care of detecting expired rows when it is written to (e.g. from SpecialUserrights)
 * and queues UserGroupExpiryJob to purge expired rows.
 *
 * Large wiki farms may experience stale rows if their users manage local groups
 * via a central wiki. In that case, UserGroupExpiryJob may run rarely or never
 * from local wikis, in which case this script can help to periodically clean up
 * expired rows.
