+that take advantage of undocumented features of AT&T Yacc will probably be
+rejected.

+to contain errors.  Neither the author nor any contributor takes responsibility
+for any consequences of its use.
+
+    Berkeley Yacc is in the public domain.  The data structures and algorithms
+used in Berkeley Yacc are all either taken from documents available to the
+general public or are inventions of the author.  Anyone may freely distribute
+source or binary forms of Berkeley Yacc whether unchanged or modified.
+Distributers may charge whatever fees they can obtain for Berkeley Yacc.
