Adding entries back to kdm menu

I upgraded to KDE 3.1.95 and in the process lost entries for Gnome, IceWM, and others in KDM. Is there an _easy_ way I'm unaware of to add these back, or do I need to mess with some config files? -- Cheers, Trey --- In answer to the question of why it happened, I offer the modest proposal that our Universe is simply one of those things which happen from time to time. --Edward P.
