In a Deblet installation, there's /var/lib/menu-xdg/applications/menu-xdg. These contain .desktop files which are very similar to Maemo's /usr/share/applications/hildon.
So, what is the challenge: Make a script that adds "relevant" (based on categories?) .desktop file, alters them to use the Easy Debian/chroot scripts for running and hence adds them to Extras so it works. It should be repeatable so it will remove all added-by-itself items first, then add debian .desktop files again.
Goal is to have for Easy Debian/Deblet that we don't have to set up static .desktop files, and the menu can be refreshed to reflect current applications installed in Deblet.
