 * 3/04/2001
 *
 * a nice little script to create exclusive, slide-out
 * menus for ns4, ns6, mozilla, opera, ie4, ie5 on
 * mac and win32. I've got no linux or unix to test on but
 * it should(?) work...

 *
 * Revised:
 * - 08/29/2002 : added .hideAll()
 * - 04/15/2004 : added .writeCSS() to support more
 *                than 30 menus.
