/**
SECTION:menuitem
@short_description: A lowlevel represenation of a menuitem
@stability: Unstable
@include: libdbusmenu-glib/menuitem.h
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.
