  <title>QuickForm Using QuickHtml Renderer</title>
<body>
<?php
/**
* Another example of usage for PEAR class HTML_QuickForm using the
* QuickHtml renderer.
*
* This renderer has three main distinctives: an easy way to create
* custom-looking forms, the ability to separate the creation of form
* elements from their display, and being able to use QuickForm in
* widget-based template systems.  See the online documentation for more
* info.
*
* @category    HTML
* @package     HTML_QuickForm
* @author      Jason Rust <jrust@rustyparts.com> 
* @version     CVS: $Id: QuickHtml_example.php 236645 2007-05-29 19:12:26Z avb $
