+<h1>Paludis, the Other Package Mangler</h1>
+
+<h2>Sets</h2>
+
+<h3>Overview</h3>
+
+<p>This document explains the concept known to Paludis as a 'set', and describes the standard
+internal sets and how to create new sets.</p>
+
+<h3>Formal Set Description</h3>
+
+<p>Internally, a set is a name with an associated dependency-style specification. In most cases
+the dependency specification will be an 'all-of' collection of package dependencies, although
+this is not a hard restriction.</p>
+
+<p>There are multiple origins for sets:</p>
+
+<ul>
+ <li>Some environment classes define their own package sets (possibly via user configuration
+ files). A set defined by the environment <em>overrides</em> any later set of the same name.</li>
+
+ <li>Most repositories define their own package sets. Some of these are defined internally --
+ examples include <code>everything</code>, <code>system</code>, <code>world</code> and
+ <code>security</code>. Repository classes may also provide a way for additional sets to be
+ defined by the repository maintainer. If multiple repositories define a named set, the
+ resulting set is all of these repository sets merged using an 'all-of' composite. The
+ <code>everything</code> and <code>world</code> sets automatically contain <code>system</code>.</li>
+
+ <li>Finally, the <code>everything</code>, <code>system</code>, <code>world</code> and
+ <code>security</code> sets always exist, even if no repositories nor the environment defines
+ them.</li>
+</ul>
+
+<p><strong>Important:</strong> a set is a named collecion of <em>dependency specifications</em>, not
+a collection of packages.</p>
+
+<h3>User Defined Sets</h3>
+
+<p>The <code>DefaultEnvironment</code> environment class allows user defined package sets via
+text files. These should be named <code><em>setname</em>.conf</code> and placed in
+<code><em>confdir</em>/sets/</code>, where <code><em>confdir</em></code> is the configuration directory
+in which <code>use.conf</code> et al. reside. The format is as follows:</p>
+
+<ul>
+ <li>Comments lines start with a <code>#</code>. These, and blank lines, are ignored.</li>
+ <li>Lines consist of a symbol, followed by whitespace, followed by a package dependency
+ atom.</li>
+ <li>The symbol <code>*</code> should be used to mean "include this package dependency atom in
+ the set".</li>
+ <li>The symbol <code>?</code> should be used to mean "include this package dependency atom in
+ the set if and only if the package part of the atom is matched by an installed package". For
+ example, the line <code>? &gt;=app-editors/vim-7</code> means requires <code>vim-7</code> if
+ and only if <code>app-editors/vim</code> (any version) is already installed.</li>
+</ul>
+
+<p>Most users will only have use for <code>*</code> lines.</p>
+
+<h3>Portage Repositories Defined Sets</h3>
+
+<p>Portage format repositories can supply their own sets. The <code>system</code> and
+<code>security</code> sets are defined programmatically; other sets are defined by a file
+named <code>sets/<em>setname</em>.conf</code>, which should be in the format described for
+user defined sets above.</p>
+
+<h3>Using Sets</h3>
+
+<p>Sets can currently be used as targets for <code>paludis --query</code> and
+<code>paludis --install</code>. In future they may be allowed in <code>use.conf</code> etc.,
+but this is currently unsupported.</p>
