You may be thinking of yyref. It's a cross-referencer for Yacc
source. Look in:


    http://www.leo.org/pub/comp/usenet/comp.sources.unix/yyref/index.html


The version I played with a couple of years ago had a couple of little
bugs.


Interesting variant: An HTML- or Java-based cross-referencer for yacc
grammars (or programs in any other language). (It's possible, though
difficult, to do this in plain HTML, due to the fact that
cross-references are many-to-many relations. You'd wind up producing
one page for each referenced symbol, and O(n^2) links in the worst
case. Using CGI or Java to dynamically create the cross-reference
pages might be a better bet.)
