// Ultimate client-side JavaScript client sniff.
// (C) Netscape Communications 1999.  Permission granted to reuse and distribute.
// Revised 7 May 99 to add is.nav5up and is.ie5up (see below). (see below).

// Everything you always wanted to know about your JavaScript client
// but were afraid to ask ... "Is" is the constructor function for "is" object,
// which has properties 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.ie3, is.ie4, is.ie4up, is.ie5, is.ie5up
// (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

// See http://www.it97.de/JavaScript/JS_tutorial/bstat/navobj.html and
// http://www.it97.de/JavaScript/JS_tutorial/bstat/Browseraol.html
// for detailed lists of userAgent strings.

//
// 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
// versions.
