*
* A #DbusmenuMenuitem is the lowest level of represenation of a
* single item in a menu. It gets created on the server side
* and copied over to the client side where it gets rendered. As
* the server starts to change it, and grow it, and do all kinds
* of fun stuff that information is transfered over DBus and the
* client updates it's understanding of the object model.
*
* Most people using either the client or the server should be
* able to deal mostly with #DbusmenuMenuitem objects. These
* are simple, but then they can be attached to more complex
* objects and handled appropriately.
