The directory system described in the previous chapter is itself
contained within <em>distribution directories</em>. Each
-distribution is contained in the <tt>dists</tt> directory in the
-top-level of the Debian archive itself (the symlinks from the
-top-level directory to the distributions themselves are for backwards
-compatability and are deprecated).

<p>
To summarize, the Debian archive has a root directory within an FTP
server. For instance, at the mirror site,
contained in <ftppath>/debian</ftppath>, which is a common location
(another is <ftppath>/pub/debian</ftppath>).
<p>
-Within that archive root, the actual distributions are contained in
-the <tt>dists</tt> directory. Here is an overview of the layout:
- <p>
-<example>
-<var>archive root</var>/dists/<var>distribution</var>/<var>section</var>/<var>architecture</var>/<var>subsection</var>/<var>packages</var>
-</example>
+A distribution is comprised of Debian source and binary packages, and the
+respective <tt>Sources</tt> and <tt>Packages</tt> index files, containing
+the header information from all those packages. The former are kept in the
+<tt>pool/</tt> directory, while the latter are kept in the <tt>dists/</tt>
+directory of the archive (because of backwards compatibility).
-Extrapolating from this layout, you know that to find the i386 base
-packages for the distribution <em>slink</em>, you would look in

There is always a distribution called <em>stable</em> (residing in
