Library/Routine for generating Freedesktop Menu?

[Kelly Miller]

I'm working on a Plasma port of Tastymenu (though mine probably won't be 
called that, for sake of avoiding confusion), and I'm curious as to 
whether kdelibs/kdebase has a function for generating the menu structure 
from the XML files already.  Does it?

Also, is there a system for the Favorites (which I noticed are shared 
across the menus in KDE4) as well?
