It (obviously) wasn't very fast, (~1 min to backward chain through about 20 loosely connected rules, if I remember correctly), but did both forward and backward chaining and had a reasonably complete set of relations. If you don't hear from anyone else, or if there is enough general interest from the net, let me know and I'll try and pretty it up enough to send to c.s.m.b and the wonderful people at sumex. Dissertation permitting, of course! Trent
