//
// adapted from Netscape's Ultimate client-side JavaScript client sniffer
// and andy king's sniffer
// Revised May 7 99 to add is.nav5up and is.ie5up (see below). (see below).
// Revised June 11 99 to add additional props, checks
// Revised June 23 99 added screen props - gecko m6 doesn't support yet - abk
//                    converted to var is_ from is object to work everywhere
// 990624 - added cookie forms links frames checks - abk
// 001031 - ie4 mod 5.0 -> 5. (ie5.5 mididentified - abk)
//          is_ie4 mod tp work with ie6+ - abk
// 001120 - ns6 released, document.layers false, put back in
//        - is_nav6 test added - abk
// 001121 - ns6+ added, used document.getElementById, better test, dom-compl
// 010117 - actual version for ie3-5.5 by Michel Plungjan
// 010118 - actual version for ns6 by Michel Plungjan
// 010217 - netscape 6/mz 6 ie5.5 onload defer bug docs - abk
// 011107 - added is_ie6 and is_ie6up variables - dmr
// 020128 - added link to netscape's sniffer, on which this is based - abk
//          updated sniffer for aol4-6, ie5mac = js1.4, TVNavigator, AOLTV,
//          hotjava
// 020131 - cleaned up links, added more links to example object detection
// 020131 - a couple small problems with Opera detection. First, when Opera
//          is set to be compatible with other browsers it will contain their
//          information in the userAgent strings. Thus, to be sure we have 
//          Opera we should check for it before checking for the other bigs.
//          (And make sure the others are !opera.) Also corrected a minor
//          bug in the is_opera6up assignment.
// 020214 - Added link for Opera/JS compatibility; added improvements for 
//          windows xp/2000 id in opera and aol 7 id (thanks to Les
//          Hill, Les.Hill@getronics.com, for the suggestion).
// 020531 - Added N6/7 and moz identifiers. 
// 020605 - Added mozilla guessing, Netscape 7 identification, and cleaner
//          identification for Netscape 6. (this comment added after code 
//          changes)
// 020725 - Added is_gecko. -- dmr
// 021205 - Added is_Flash and is_FlashVersion, based on Doc JavaScript code. 
//          Added Opera 7 variables. -- dmr
// 021209 - Added aol8. -- dmr
// 030110 - Added is_safari, added 1.5 js designation for Opera 7. --dmr
// 030128 - Added is_konq, per user suggestion (thanks to Sam Vilain).
//          Removed duplicate Opera checks left over after last revision. - dmr
// 031124 - Added is_fb and version. We report this right after the is_moz
//          report. - dmr
// 040325 - Added is_fx and version. We report this right after the is_moz
//          report. - dmr
// 040421 - Added Debian check to is_moz. Thanks to Patrice Bridoux for
//          reporting this.
// 040517 - Added is_fb/is_fx to plugins based flash detection. Thanks to 
//          Martin Bischoff for pointing out this omission.
// 040617 - On Mac IE, appVersion differs from the version in the ua, 
//          with the UA appearing to be more accurate. As an experiment, 
//          for Mac we'll pull is_minor from the ua instead.

//     is_nav6, is_nav6up, is_ie3, is_ie4, is_ie4up, is_ie5up, is_ie6...
// (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

// 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. For DOM tests scripters commonly used the 
// is_getElementById test, but make sure you test your code as
// filter non-compliant browsers (Opera 5-6 for example) as some 
// browsers return true for this test, and don't fully support
// the W3C's DOM1.
