btyacc - 3.0-5+b2 main

btyacc is a hacked version of the original Berkeley "byacc". The main
change to byacc is the addition of backtracking code, allowing you to
try both alternatives in case of shift-reduce or reduce-reduce
conflicts. As long as no backtracking takes place, speed is comparable
to bison.

Additional features:
