+"""
+DCOPExObj provides all of the necessary machinery to DCOP-enable
+an application: the 'process' method, marshalling/demarshalling,
+and the 'features' method
+
+To DCOP-enable an app,
+
+    1. Add a class which subclasses DCOPExObj (ParrotObject in
+       this case). Call the DCOPExObj.__init__ method with 'id'.
+       If 'id' isn't specified, DCOP will assing a numerical id.
+       'id' is the name of the object (eg, how it will be listed
+       in kdcop, or returned with a dcopClient.remoteObjects call)
+
+    2. Identify the methods/functions that will be exposed via
+       DCOP - they don't have to be methods of the DCOPExObj
+       class, as long as the DCOPExObj class can call them. Make
+       sure they take/return types that DCOPExObj supports.
+
+    3. For each method, call self.addMethod with the complete
+       method signature (return type, name, list of argument
+       types, but no argument names) as a string and the
+       Python method/function that corresponds.
+
+    4. That's it.
