// Ultimate client-side JavaScript client sniff.
// (C) Netscape Communications 1999.  Permission granted to reuse and distribute.
// Revised 20 April 98 to add is_nav5up and is_ie5up (see below).

// 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
//     is_mac, is_mac68K, is_macppc
//     is_unix
//        is_sun, is_sun4, is_sun5, is_suni86
//        is_irix, is_irix5, is_irix6
//        is_hpux, is_hpux9, is_hpux10
//        is_aix, is_aix1, is_aix2, is_aix3, is_aix4
//        is_linux, is_sco, is_unixware, is_mpras, is_reliant
//        is_dec, is_sinix, is_freebsd, is_bsd
//     is_vms

// See http://www.it97.de/JavaScript/JS_tutorial/bstat/navobj.html and

//
// Note: you don't want your Nav4 or IE4 code to "turn off" or
// stop working when Nav5 and IE5 (or later) are released, so
// in conditional code forks, use is_nav4up ("Nav4 or greater")
// and is_ie4up ("IE4 or greater") instead of is_nav4 or is_ie4
// to check version in code which you want to work on future
