This program borrows many ideas from LambdaMOO, written by Stephen White and Pavel Curtis, and COOLMUD, written by Stephen White. The database routines in this code in chunk.c originate from code by Marcus J. Ranum, although only the block allocation algorithm is currently similar to his code. The cache algorithm also uses his ideas. The regular expression matcher used by Coldmud (regexp.c) was written by Henry Spencer. Numerous people have contributed valuble ideas and debugging effort. Among them are Jay Carlson, Erik Ostrom, Matthew Rhoten, Loyd Blankenship, Gregory Blake, Jeff Prothero, Nils McCarthy, Brandon Gillespie, Ron Strait, Alex Stewart, Jordan Baker, Ryan Daum, and Doug Orleans.
