Well, there's lex itself obviously.  I'm not sure whether bison will
actually work with it, and I guess the majority of lex afficionados will
probably be using yacc rather than bison in any case, so it probably
isn't all that big a deal.  But if bison does indeed support non-flex
implementations of lex then it would be nice to expose that in the
metadata.
