From: Allen VanGelder <avg@diablo> [Forwarded from the Stanford bboard by Laws@SRI-AI.] NAIL is a research project one of whose goals is to determine what degree of expressiveness and efficiency can be obtained by a logic based language without resorting to certain "undesirable" non-logical mechanisms such as cut, assert and retract, rule order, and subgoal order. Jeff Ullman, the PI, likes to draw the analogy: "NAIL is to Prolog as Relational DBMS is to CODASYL." NAIL is in a preliminary stage of development at Stanford CSD. An overview, "Design overview of the Nail! System" is available from Professor Ullman. NAIL! is an acronym for "Not Another Implementation of Logic!"
