Linley's Dungeon Crawl (or just Dungeon Crawl or Crawl) was a roguelike computer game originally programmed by Linley Henzell in 1995, and first released to the general public on October 2, 1997. The game had a quirky license based on Bison's license and the NetHack License; Stone Soup has contacted every past contributor and relicensed to GPL-2.0-or-later.
