%description
Berkeley Yacc is an LALR(1) parser generator.  Berkeley Yacc has been made
as compatible as possible with AT&T Yacc.  Berkeley Yacc can accept any input
specification that conforms to the AT&T Yacc documentation.  Specifications
that take advantage of undocumented features of AT&T Yacc will probably be
rejected.
