Distributed Logic Programming

    (DLP) A logic programming language similar to
   Prolog, combined with parallel object orientation similar
   to POOL.  DLP supports distributed backtracking over the
   results of a rendezvous between objects.  Multi-threaded
   objects have autonomous activity and may simultaneously
   evaluate method calls.
