-<h2>link()</h2>

-<p>Lets you create HTML &lt;link /> tags.  The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.</p>

-<p>While stylesheets are more conveniently handled through the stylesheet() function, they can also be called here.</p>
