  "OPS5 Users Manual," Charles L. Forgy, 1981, CMU Tech.
   Report CS-81-135.  (the syntax & semantics)

  "Rete: A Fast Algorithm for the Many Pattern/Many Object Pattern
   Match Problem," Charles L. Forgy, 1982, _Artificial_Intelligence_,
   no. 19, pp. 17-37.  (the algorithm)

  "The OPS83 Report," Charles L. Forgy, 1984, CMU Tech.
   Report CS-84-133.

OPS83 is a commercial product.  It does not run under Lisp
as does OPS5, but is directly compiled. and the RHS language
has control structures such as loops, instead of just the
pure production system model of OPS5.
