+ * This demo shows that you can find out what interface an object has and
+ * what types it needs to work without knowing anything but the object
+ * reference.
+ *
+ * The reason for that is that every object offers the _interfaceName
+ * _queryInterface and _queryType methods, which you can use to find out
+ * anything you need to know to talk to that object.
+ *
+ * Just pass this programm an MCOP object reference, and it will print out
+ * the corresponding interface.
+ *
+ * (TODO: one could make it print out all inherited interfaces and the
+ * types that are used in the interface, too. Ports, etc could be shown
+ * as well).
