+    <p>If the gen_event should be able to receive other messages than
+      events, the callback function <c>handle_info(Info, StateName, StateData)</c>
+      must be implemented to handle them. Examples of
+      other messages are exit messages, if the gen_event is linked to
+      other processes (than the supervisor) and trapping exit signals.</p>
