Doomloader (which is something like a lame Doomer) is available
in tgz and deb files (Linux/unix and Debian).
It's a lame perl script launched by the shell script you want.
For example, if you want to commit suicide, you just type
"alienvendetta.sh -warp 26 -skill 5". If you want to understand why you
died, type "alienvendetta.sh --dlwadinfo".
It still have bugs, the perl code is lame, but it works.
Get it at http://ellisllk.lautre.net/jeux/doomlike/doomloader.0.9.tgz or
http://ellisllk.lautre.net/jeux/doomlike/doomloader_0.9_all.deb.
Don't forget: read the damn manpage and code!

I'd like to write a GNOME GUI for it, but I'm too lame.
