<p>This plugin allows you to manually enter links that are related to a post.  They<br />
can be on any site and you can enter just the URL or an entire link (specifying<br />
the title attribute, onclicks, etc).  There are helper functions to display them<br />
in your theme or you can simply tell the plugin to automatically add them to<br />
posts or even just single posts.  The list is output as an unordered list (ul)<br />
with an optional title, and everything has CSS classes to make styling easy.<br />
Requires PHP5.</p>
