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.
