I am looking for references to tools for manipulating or debugging
For instance, one such tool might illustrate ambiguities in a grammar
by exhibiting sequences of grammar symbols that can be parsed more than
one way (and hopefully showing at least two derivation trees). It can
be hard to debug a grammar with the y.output file that yacc produces
since conflicts can occur in a very different part of the grammar than
where the fix "really should" be made.
I would appreciate ideas for other sorts of tools for grammar debugging
