Provide a desktop menu file that uses "debmany.png". When configuring the desktop
call follow this table:

             kde      gnome    xfce
             required     zenity   zenity   zenity,xdg-utils
             parameters   -k -z    -g -z    -x -z

It is better to use the -l parameter for ISO 639 two-letter language code and
"*" at the end.

Example parameters for a german Kde user: -k -z -l "de*"

Optionally, Depend: on xdg-utils package, too. Then the desktop file can use the arguments
-x instead of -k, -g or -x for all desktops.
