Writing the Makefile

OpenBSD ports rely on Makefile s. A basic layout is:

	# New ports collection makefile for:   set-difference
	# Date created:        10 December 2007
	# Whom:                Pierre-Alexandre Meyer
	#
	# $FreeBSD$
	#

	PORTNAME=      set-difference
	PORTVERSION=   1.0
	CATEGORIES=    mathematics
	MASTER_SITES=  http://www.mouraf.org/projects/set_difference

	MAINTAINER=    pam@mouraf.org
	COMMENT=       Compute the set difference between two arrays.

	.include <bsd.port.mk>
