// Ultimate client-side JavaScript client sniff. 
// (C) Netscape Communications 1999.  Permission granted to reuse and distribute. 
// Revised 17 May 99 to add is_nav5up and is_ie5up (see below). 
// Revised 03 July Stephen North steve@fissh.com 
// Everything you always wanted to know about your JavaScript client 
// but were afraid to ask. Creates "is_" variables indicating: 
// (1) browser vendor: 
//     is_nav, is_ie, is_opera 
// (2) browser version number: 
//     is_major (integer indicating major version number: 2, 3, 4 ...) 
//     is_minor (float   indicating full  version number: 2.02, 3.01, 4.04 ...) 
// (3) browser vendor AND major version number 
//     is_nav2, is_nav3, is_nav4, is_nav4up, is_nav5, is_nav5up, is_ie3, is_ie4, is_ie4up 
// (4) JavaScript version number: 
//     is_js (float indicating full JavaScript version number: 1, 1.1, 1.2 ...) 
// (5) OS platform and version: 
//     is_win, is_win16, is_win32, is_win31, is_win95, is_winnt, is_win98 
//     is_os2
