It is written in Ratfor and consists of a front-end that reads Yacc grammars, writing a grammar in a slightly different format. The back end builds an LR parser table using an adaptation of another public-domain program. (Sorry, I don't have the details in front of me). The parser tables are not identical to Yacc's, and could stand a bit of time optimization. I've translated the Ratfor sources to C, but don't feel the result is stable enough to distribute.
