+I have written an S-R parser. Much more flexible and powerful than
+YACC. (It will generate four types of parsers: SLR(0), SLR(1), LR(1),
+and LALR(1)). I currently use it for parsing English. I have
+augmented the CFG with tests and actions: features, registers, etc.
+I use GPSG formalism for unbounded movement. Typed-lambda calculus
+semantic rules interleaved with the syntactic rules.
+
+When things cool down a little, I hope to clean it up for
+distribution. I have not decided exactly what to distribute, so I am
+interested in hearing what people are interested in. The full-blown
+NLU version is not ready to go, but it won't take much to strip it down
+to something useful and reliable.
+
+My access to the News groups is shaky, so I would appreciate it if
+someone would post this information to the LISP group.
+
+Thanks. --Jim
