There's a XML file beside e.g. the hello example. Maybe you should
start to learn more about the introspection format:

http://dbus-cplusplus.wiki.sourceforge.net/Introspection+Format

Try the simple case with one method/signal, play with parameters and
see what the generator creates as output. If you understood the
introspection format half of the work is done. You've to use the
generated header files in your application.

I really have to write a beginners guide in the wiki. If you've success
be welcome to write something.

Please help to change the situation! :)
