This is a classic command, used on many MUDs, but probably most influenced by the Mystic Adventure one. It changes the auction channel into an automated one, giving the buyers the ability to see the stats of an item and bid on it. One item is auctioned at a time. Version 3 contains no new features, just an answer to a question I've been asked about 50 times now.
Version 3, last update: November 97.
