	<h3>What does this tag do?</h3>
	<ul>
	<li>Output Browser Name and/or Browser Version</li>
    <li>more to come later</li>
	</ul>
	<h3>How do I use this tag?</h3>
<blockquote><b>Just insert the tag into your template/page like in one of the examples here: </b><br />
  <CODE>1. {browsertools output="browser"}</CODE>
  </blockquote>
	<h3>What parameters does it take?</h3>
	<ul>
	<li><CODE>action</CODE> <em>(optional)</em> <strong>default:'retrun'</strong> - 'test', 'isMobile'</li>
    <li><CODE>against</CODE> <em>(optional)</em> <strong>default:''</strong> - pass a string to test against. ie: msie8.0 <strong>Retruns true/false</strong></li>
    
    <li><CODE>output</CODE> <em>(optional)</em> <strong>default:'full'</strong> - 'browser','version','platform' </li>
    <li><CODE>assign</CODE> <em>(optional)</em> - assign the output to a smarty variable</li>
    <li><CODE>strip_space</CODE> <em>(optional)</em> - Strip the spaces that are in the output by default<em> ex: Internet Explorer 8 would output msie8.0</em><strong>NOTE:only works with output 'full'</strong></li>
    <li><CODE>dot_replace</CODE> <em>(optional)</em> - Set for different version display formatting <em><strong>Note:</strong> If you don't use the version will use . so you'll have 7.0</em></li>

 	<h3>Uses for what parameters output?</h3>   
	<CODE>1. {browsertools action="sniff" Output="Name,Version" dotReplace="-"}</CODE> Outputs something like msie 7-0 which can be used in classes <em>class="<CODE>{browsertools action="sniff" Output="Name"} V_{browsertools action="sniff" Output="Version" dotReplace="-"}</CODE>" giving class="msie V_7-0"</em><br/>
