I once needed two lex-yacc parsers in the same program.  I used the
stream editor "sed" to edit the C code generated by lex & yacc on one
of the parsers.  It replaced every occurence of "yy" with "ww".  This
worked because all lex-yacc externals start with "yy".  I also supplied
the needed external procedures such as "wwerror".  My sed script also
renamed the main parser routine, but kept the same number of letters,
just to be safe.

This approach worked fine, but it was just quick & dirty code for an
experiment; it wasn't production quality code.
