+      Berkeley Yacc (byacc) is generally conceded to be the best yacc variant
+      available. In contrast to bison, it is written to avoid dependencies upon
+      a particular compiler.
+
+      Byacc was written around 1990 by Robert Corbett who is the original author
+      of bison. Byacc is noted in Lex & Yacc by John Levine et al (O'Reilly,
+      1992) for its compatibility with the original yacc program.
+
+      Nowadays byacc is maintained by Thomas E. Dickey.
