If you want to check for specific browsers/versions then use this class to parse the user agent string and use the accessor methods in this class. JavaScriptOK means that the browser understands JavaScript on the same level the Navigator 3 does. Specifically, it can use named images. This allows easier rollovers. If a browser doesn't do this (Nav 2 or MSIE 3), then we just assume it can't do any JavaScript. Referencing images by load order is too hard to maintain. CSSOK is kind of sketchy in that Nav 4 and MSIE work differently, but they do seem to have most of the functionality. MSIE 4 for the Mac has buggy CSS support, so we let it do JavaScript, but no CSS.
