SLASHEM PHLEGETHON

The CVS repository of SLASH'EM contains a SLASHEM_PHLEGETHON branch, an attempt to finish merging the Lethe patch into SLASH'EM. Unlike SLASH'EM 0.0.7E7F2, which has the new monsters but not the new levels, and unlike SLethe, which simply replaces the SLASH'EM Gehennom with the Lethe Gehennom, the goal of the this branch is to require players with the Amulet of Yendor to take an alternate route out of the dungeon.
