Files for Cataclysm MUD.

Cataclysm MUD is a continuation of tbaMUD/CircleMUD, which is built on DIKU MUD. The code here is freeware to honor that tradition. Licensing and use should be based on what was outlined previously. Any new code added here is released under the same license.

Due to the sensitive nature of topics found in this setting, all characters and players are 18+. The game world is derived from several inspirational sources, most notably the former Armageddon MUD.

Roleplay is highly encouraged.
