<p>This plugin adds two areas of functionality: Global page, category or tag permalink structures and individual custom permalinks.</p>
<p>Options are added to the Permalinks Settings page allowing you to specify the structure for pages, categories, tags and authors.</p>
<p>By default – if custom permalinks are enabled – pages are accessible in the format <code>/page/</code> or <code>/parent/page/</code>.</p>
<p>You can modify this format in many different ways, for example:</p>
<ul>
<li>Add an extension: <code>/%pagename%.html</code></li>
<li>Add a parent directory name: <code>/content/%pagename%/</code></li>
<li>Prefix the page name: <code>/page-%pagename%/</code></li>
<li>Or using a combination of the above.</li>
</ul>
<p>This same format applies for categories, tags and authors, however the structure tokens differ:</p>
<ul>
<li>Categories: <code>%category%</code> (E.g. <code>/category/%category%.html</code>)</li>
<li>Tags: <code>%post_tag%</code> (E.g. <code>/tag/%post_tag%.html</code>)</li>
<li>Authors: <code>%author%</code> (E.g. <code>/author/%author%.html</code>)</li>
</ul>
<p>Each <em>permalink base</em> can be edited directly via these settings, for example using <code>/people/%author%.html</code> as the Author permalink structure will replace <code>/author/</code> with <code>/people/</code>.</p>
<p>If no prefix is found, permalinks will be prepended with a default (category, tag or author) – with the exception of pages.</p>
<p><strong>Note:</strong> Ensure you have included the correct structure tag somewhere in the url.</p>
<p>Additionally, an option is added to the edit screen allow you to specify the permalink for an individual post or page.</p>
