Chapter 12. A simple example of a package: bison

I checked to find a piece of software that isn't in the FreeBSD ports collection, and picked GNU bison. Quite why someone would want to have bison when Berkeley yacc is already present in the tree is beyond me, but it's useful for the purposes of this exercise.

	# $NetBSD$
 
	DISTNAME=       bison-1.25

	.include "../../mk/bsd.pkg.mk"

	GNU yacc clone.

	GNU version of yacc.  Can make re-entrant parsers, and numerous other
	improvements.  Why you would want this when Berkeley yacc(1) is part
	of the NetBSD source tree is beyond me.
