byacc:
byacc: Berkeley Yacc is an LALR(1) parser generator.  Berkeley Yacc
byacc: has been made as compatible as possible with AT&T Yacc.  Berkeley
byacc: Yacc can accept any input specification that conforms to the AT&T
byacc: Yacc documentation.  Specifications that take advantage of
byacc: undocumented features of AT&T Yacc will probably be rejected.
byacc: If you skip this package and install GNU bison, a /usr/bin/yacc
byacc: shell script will be created which will allow you to use bison
byacc: instead. (It contains 'bison -y $*')
