<p>Pages Autolink is a SEO plugin which automatically turns page names, when used in posts and pages, in links to the corresponding page URLs. Keeps the original words case in text. It’s particulary useful for bloggers who build a glossary using pages, for each time a word of the glossary is used in the site it is automatically converted in a link to its explanation.</p>
<h3>Arbitrary section</h3>
<p>You may provide arbitrary sections, in the same format as the ones above.  This may be of use for extremely complicated<br />
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or<br />
“installation.”  Arbitrary sections will be shown below the built-in sections outlined above.</p>
