comments, using the <code class="literal">edown</code> application:</p><pre class="programlisting">DOC_DEPS = edown

automatically if the <span class="emphasis"><em>doc/overview.edoc</em></span> file exists. If you
do not want that file and still want to generate doc comments,
two solutions are available.</p><p>You can generate EDoc documentation directly:</p><pre class="programlisting">$ make edoc</pre><p>You can enable automatic generation on <code class="literal">make docs</code> by adding
the following to your Makefile:</p><pre class="programlisting">docs:: edoc</pre></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="asciidoc.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="docs.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="tests.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top"> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> </td></tr></table></div>
