Creation/Dev/Mudlib
From Graal Bible
The Mudlib provides Graal Kingdoms and, by extension, Graal2002 Debug, and Maloria Dev with its extra Multi-User Dungeon options. Hence the "mud" part. You see?
This library also extends GScript with a few extra commands that allow it to access and modify MUD accounts.
The Graal Kingdoms mudlib is derived from Crossfire.
