/* 
 * ie-note.js -- alerts users of IE about lack of standards-compliance
 *
 * to use, source this script from the HTML file:
 *
 *   <script type="text/javascript" src="js/ie-note.js"></script>
 *
 * Note that you need an event handler, such as
 *   http://dean.edwards.name/weblog/2005/10/add-event/
 * or insure otherwise that insertNote() is called *after* the whole page has
 * been rendered and the DOM initialised.
 *
 * The notice can be styled with CSS, using the ie-note class name.
