<h2><img src="../images/info.gif"/> Introduction</h2>
<p>This example requires :
<ul>
<li>PEAR::HTML_Progress 1.2.2 or better (see source at lines 11, 12).</li>
</ul>
</p>
<hr/>
<p><b>This example will run a ProgressBar with a custom class observer mechanism.
Output could be send to screen or on flat file 'observer_complex.log'.</b></p>
<p>Here are the contents of that file :
