    <p>Apache 2.4 uses <a href="http://www.doxygen.org/">Doxygen</a> to
    document the APIs and global variables in the code. This will explain
    the basics of how to document using Doxygen.</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="brief" id="brief">Brief Description</a></h2>
    <p>To start a documentation block, use <code>/**</code><br />
    To end a documentation block, use <code>*/</code></p>

    <p>In the middle of the block, there are multiple tags we can
    use:</p>

    <div class="example"><p><code>
      Description of this functions purpose<br />
      @param parameter_name description<br />
      @return description<br />
      @deffunc signature of the function<br />
    </code></p></div>

    <p>The <code>deffunc</code> is not always necessary. DoxyGen does not
    have a full parser  in it, so any prototype that use a macro in the
    return type declaration is too complex for scandoc. Those functions
    require a <code>deffunc</code>. An example (using &amp;gt; rather
    than &gt;):</p>

    <div class="example"><p><code>
      /**<br />
 &nbsp;* return the final element of the pathname<br />
 &nbsp;* @param pathname The path to get the final element of<br />
 &nbsp;* @return the final element of the path<br />
 &nbsp;* @tip Examples:<br />
 &nbsp;* &lt;pre&gt;<br />
 &nbsp;*                 "/foo/bar/gum"   -&amp;gt; "gum"<br />
 &nbsp;*                 "/foo/bar/gum/"  -&amp;gt; ""<br />
 &nbsp;*                 "gum"            -&amp;gt; "gum"<br />
 &nbsp;*                 "wi\\n32\\stuff" -&amp;gt; "stuff"<br />
 &nbsp;* &lt;/pre&gt;<br />
 &nbsp;* @deffunc const char * ap_filename_of_pathname(const char *pathname)<br />
 &nbsp;*/
    </code></p></div>

    <p>At the top of the header file, always include:</p>
    <div class="example"><p><code>
      /**<br />
 &nbsp;* @package Name of library header<br />
 &nbsp;*/
    </code></p></div>

    <p>Doxygen uses a new HTML file for each package. The HTML files are named
    {Name_of_library_header}.html, so try to be concise with your names.</p>

    <p>For a further discussion of the possibilities please refer to
    <a href="http://www.doxygen.org/">the Doxygen site</a>.</p>
