+
+  If the refresh-period (minutes) is non-zero, this charm will reexecute the SQL tar dump
+  after that number of minutes have passed since the last update.
+
+  This charm can be configured with the db-user config option, which will be the new
+  owner of the newly created data (otherwise, consumers of that database will encounter
