+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.
