+ServerSession
+
+The serversession is the Server-side in-memory representation of a
+user connecting to the game.  Evennia manages one Session per
+connection to the game. So a user logged into the game with multiple
+clients (if Evennia is configured to allow that) will have multiple
+sessions tied to one Player object. All communication between Evennia
+and the real-world user goes through the Session(s) associated with that user.
+
+It should be noted that modifying the Session object is not usually
+necessary except for the most custom and exotic designs - and even
+then it might be enough to just add custom session-level commands to
+the SessionCmdSet instead.
+
+This module is not normally called. To tell Evennia to use the class
+in this module instead of the default one, add the following to your
+settings file:
+
+    SERVER_SESSION_CLASS = "server.conf.serversession.ServerSession"
