y2l takes a yacc(1) grammar description file and generates an EBNF (Extended Backus-Naur Form) grammar from it. By default, the output will be a LaTeX(1) longtable environment, that can be \input{} into any LaTeX document. Automatic substitution of symbolic terminals can also be taken care of. Options control whether any optimization should be done on the grammar, and whether plain ASCII output should be generated instead.
