Yes, I have been writing a Perl script (5.004) to convert to YACC and
LEX. However, I have not really tested it on a useful "language". The
idea was to get BNF grammers for VLSI CAD and somehow make a reverse
compiler from an intermediate parsed description. This would allow a
means to interface between different CAD languages .....
