The way it works is the following:
* all desktops install their main menu as blah-applications.menu
(e.g. kde3-applications.menu)
* however, we do not want the merged directory name to be constructed
from the menu name, because we want all applications and desktops to
install merged files into the same directory: applications-merged, so
that everyone benefit from it.
