  26  * Remove expired userrights from user_groups table and move them to former_user_groups.
  27  *
  28  * By default, this does not need to be run. The UserGroupManager service naturally
  29  * takes care of detecting expired rows when it is written to (e.g. from SpecialUserrights)
  30  * and queues UserGroupExpiryJob to purge expired rows.
  31  *
  32  * Large wiki farms may experience stale rows if their users manage local groups
  33  * via a central wiki. In that case, UserGroupExpiryJob may run rarely or never
  34  * from local wikis, in which case this script can help to periodically clean up
  35  * expired rows.
