+Automatically unlock square
+---------------------------
+
+The `unlock_square.sql` upkeep script unlocks a square that is locked for more
+than two hours.
+
+Update areas statistics
+-----------------------
+
+The `update_areas_statistics.sql` script updates *squares to map*, *squares to
+review* and *squares done* fields of all *current* areas (areas with a priority
+greater than zero.)
+
+Delete archived areas
+---------------------
+
+When an area has priority `-10`, the `delete_areas_with_priority_-10.sql`
+script deletes such an area including all its squares and commits during the
+upkeep.
+
+**NOTE:** It works only for the areas with priority `-10`. For other archived
+areas (areas with priority less than zero,) there is no special upkeep script
+yet.
