Howto add window managers to gdm?

["Larry Alkoff" <labradley@mindspring.com>]

I'd like to add the following window managers to gdm:

afterstep
black box 
fvwm2
sawfish
windowmaker
xfce
enlightment

I'm running Libranet 2.7 based on Debian.
Evidently the menu is controlled by files in 
/etc/gdm/Sessions

This presently contains Gnome, KDE, Libranet (ICEwm-experimental), XFce and Fluxbox
plus Default soft linked to (presently) KDE.

I'd like to add the others above but each of the existing files has a completely different
command line and I don't know how to proceed.

Is there a resource where I can get information on this?  I've tried the obvious ones.
