The Lemon Parser Generator Lemon is an LALR(1) parser generator for C or C++. It does the same job as ``bison'' and ``yacc''. But lemon is not another bison or yacc clone. It uses a different grammar syntax which is designed to reduce the number of coding errors. Lemon also uses a more sophisticated parsing engine that is faster than yacc and bison and which is both reentrant and thread-safe. Furt
