 1. Create the xml file - this xml file should have the interfaces 
that can be viewed by the qdbus-view in the system either on 
the system or session bus.

    2.With the utility - qdbusxml2cpp , you generate the interface adaptor code. 
This interface adaptor does the demarshalling of the data that is 
received from the client. After demarshalling, it invokes the 
user defined - custom methods ( we can say as adaptee).

    3. At the client side, we generate the interface from the xml file. 
This interface is invoked by the client. The interface does the 
marshalling of the data and invokes the adaptor interface. As told 
in the point number 2, the adaptor interface does the demarshalling 
and calls the adaptee - user defined methods.
