Basically Slump is a fork of SLIGE that is optimized for making FreeDoom maps. In particular, Slump only places monsters that the FreeDoom artists have drawn in to maps; this way one can play FreeDoom without feeling that the game is incomplete.
The current version of Slump is version 0.003.02, released October 29, 2007. (click on link to download; GPG sig). A changelog and links to previous versions is at the bottom of this page. Also available is a Windows binary of Slump, a sample FreeDoom/Doom2 wad file (generated with "slump -seed 1 -rooms 7"), and full documentation for SLUMP.
Slump is relesed under the GPL with two optional requests added to the license:
