+  Module "lastmsg"    -- adds a /lastmsg command
+                         Displays last personal messages
+
+  This modules stores messages received in a MUC room while
+  you are away (or not available) if they contain your nickname.
+  When you're back, you can display them in the status window with
+  the /lastmsg command.
+  Note that this module is dumb: if your nick is foo and somebody
+  says "foobar" the message will be stored!
