Ubuntu: generate program menus

generates programs menu for all menu-aware applications
Debian menu keeps transparently the menus in the different
window-managers in sync with the list of installed programs.

Debian menu relies on a list of menu entries provided by programs
and a list of menu-methods provided by window-managers and other
menu-aware applications.

Menu provides system-level and user-level configuration and overrides
for both menu entries and menu-methods.

$ sudo apt-get install menu
$ sudo apt-get install menu-xdg #not sure about this
