This package allows you to create in one step the configuration files for the fvwm, fvwm2, fvwm95, bowman, afterstep, cdesim, mwm, and ctwm window managers.
In the menus you'll only find programs which are really installed in the system. The desktop of the seven window managers will look the same (considering the particularities of the window managers). In version 1.5 for mwm and ctwm there is only support for keeping the menus actual since these two are very different from the five other window managers.
The icons used in the fvwm2 / fvwm95 menus are taken from the package 3dpixms which themselves are generated from the 3dpixm package.
You can find some information in /usr/doc/packages/susewm. The documentation is also accessible by the desktop menu.
