I need to hide the following sifr javascript line of code from just IE6.

Code HTML4Strict:
<script type="text/javascript" src="scripts/sifr.js"></script>
<script type="text/javascript" src="scripts/sifr-config.js"></script>

This hides it from all browsers, i want it to just hide from IE6
Code HTML4Strict:
<!--
<script type="text/javascript" src="scripts/sifr.js"></script>
<script type="text/javascript" src="scripts/sifr-config.js"></script>
-->

Any ideas?
