CD gamedriver and CD mudlib (also known as CDlib) are popular LPMud gamedriver and mudlib. The name CD comes from Chalmers Datorförening (Chalmers Computer Society), which most of the developers were members of.


In late 1991, Lars Pensjö, creator of Genesis LPMud and of LPMud itself, retired from Genesis. The rest of the administration has decided to create CD as a fork from Lars's development version of LPMud, known as LPMud 3.0.[1]

Retrieved on 2010-04-18. "Late 1991 ¶ After the retirement of Lars from _Genesis_, the _Genesis_ admins move to create the first LPMud-derived server, CD. CD stands for Chalmers Datenforung, Swedish for Chalmers Computing Club, where _Genesis_ and _Igor_ existed. In spite of his retirement from _Genesis_, Lars continued to develop"

"Unlike other MUDs, Genesis requires your character to first introduce himself to other players before you can see their names (you don't automatically know people's names in RL, do you?)."

"The CD Mudlib has an actual concept of generic terrain types that appear on a map. For example, the basic terrain types that are available with the CD source code is in space; the terrains available here, although really a misnomer if you think about it, include space, asteroid belt, and so on. Terrains can affect a player if any special functions are specified. These terrains are similar to the autoroom generator."
