	  <small>Describes the approach used by the FreeBSD release
	    engineering team to produce a high quality package set
	    suitable for official FreeBSD release media.  This document is
	    a work in progress, but eventually it will cover the process
	    used to build a clean package set on the FreeBSD.org "Ports
	    Cluster", how to configure any other set of machines as a
	    ports cluster, how to split up the packages for the release
	    media, and how to verify that a package set is
	    consistent.</small></p></li>
