+// CLASS DESCRIPTION (MPolyMessage)
+//
+// This class is used to register callbacks for poly messages.  Currently,
+// you can use this class to listen to component id changes for vertices,
+// edges and faces.
+//
+// To remove a callback use MMessage::removeCallback.
+// All callbacks that are registered by a plug-in must be removed by that
+// plug-in when it is unloaded. Failure to do so will result in a fatal error.
