It's an expert system development system.  According to my friends who
know about such things, it compares favorably with extremely expensive
systems running on large LISP machines.

forward and backward chaining, controllable within rules.

About $5,000 (yes, five thousand dollars).  Neuron Data, 444 High Street,
Palo Alto, CA 94301.  (415) 321-4488.  The price is high because they
see themselves as competing with Symbolics systems that cost nearly an
order of magnitude more for a complete system (hardware and software).

Just saw a demo.  It looked great.  Nice user interface.
