+summary: Yet another MUC reliability module

+...
+
+
+This module reacts to [server-to-server][doc:s2s] connections closing by
+performing [XEP-0410: MUC Self-Ping] from the server side to check if
+users are still connected to MUCs they have joined according
+[mod_track_muc_joins].  If it can't be confirmed than the user is still
+joined then their client devices are notified about this allowing them
+to re-join.
