// Ultimate client-side JavaScript client sniff. Version 3.01
// (C) Netscape Communications 1999-2001.  Permission granted to reuse and distribute.
// Revised 17 May 99 to add is_nav5up and is_ie5up (see below).
// Revised 20 Dec 00 to add is_gecko and change is_nav5up to is_nav6up
//                      also added support for IE5.5 Opera4&5 HotJava3 AOLTV
// Revised 22 Feb 01 to correct Javascript Detection for IE 5.x, Opera 4, 
//                      correct Opera 5 detection
//                      add support for winME and win2k

// (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

// (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_winme, is_win2k
