<h2>Installation</h2>
<p>If possible, get this package from your distribution using its
installation manager. Alternatively, copy/move/link <span class="docutils literal">docutils.sty</span>
to a place where LaTeX can find it.</p>
</section>
<section id="usage">
<h2>Usage</h2>
<p>The package is intended for use with LaTeX documents generated from
<a class="reference external" href="https://en.wikipedia.org/wiki/ReStructuredText">reStructuredText</a> sources with <a class="reference external" href="https://docutils.sourceforge.io/">Docutils</a>.</p>
<p>When generating LaTeX documents, specify this package with the
<a class="reference external" href="https://docutils.sourceforge.io/docs/user/config.html#stylesheet-latex-writers">“stylesheet”</a> <a class="reference external" href="https://docutils.sourceforge.io/docs/user/config.html">configuration option</a>, e.g.</p>
<pre class="literal-block">rst2latex --stylesheet=docutils exampledocument.txt</pre>
<p>The the Docutils <cite>LaTeX writer</cite> will then reference this package
istead of inserting required definitions into the preamble of
generated documents (see the <a class="reference external" href="https://docutils.sourceforge.io/docs/user/latex.html">Docutils LaTeX Writer documentation</a>
for details).</p>
