We sell ydb, a symbolic debugger for yacc grammars and parsers which 
provides a large set of tools for manipulating and debugging yacc grammars;
the package also includes a run time debugger for debugging parsers.
Look for full details on comp.newprod when it returns from the dead,
or drop us a note for more information.
