<script language="javascript">
<!--
sfHover = function() {
var sfEls = document.getElementById("side").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {
	sfEls[i].onmouseover=function() {
		this.className+=" sfhover";
	}
	sfEls[i].onmouseout=function() {
		this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
	}
}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);

-->
