Scanner/parser generator

'Styx' is a scanner/parser generator designed to address some shortcomings of the traditional lex/yacc combination. Its features include automatic derivation of depth grammar, production of the derivation tree (including its C interface), preservation of full source information, pretty printing to faciliate source to source translation, and persistence to aid rapid interpreter writing, and support for re-entrancy.
