		<para>
			This paper is intended for people who are interested in the philosophy
			of Debian Pure Blends (in short "Blends" if it is used clearly in
			internal Debian context), and the technique that is used to manage
			those projects.  For those who are familiar with the concept of Custom
			Debian Distributions: We just found a new name for this concept
			because the old name just not expressed what actually is done.  It is
			explained in detail why Blends are not forks from Debian, but reside
			completely inside the Debian GNU/Linux distribution, and which
			advantages can be enjoyed by taking this approach.  The concept of
			metapackages and user role based menus is explained.  In short: This
			document describes why Debian Pure Blends are important to the
			vitality and quality of Debian.
