// please send any improvements to aking@internet.com and we'll
// roll the best ones in
//
// 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
// 030617 - Minor error corrections, two missing semicolons.
// Also made a couple changes to, IMHO, improve readability.
// Added is_MediaPlayer, is_MediaPlayer64, and is_MediaPlayer7up,
// based on code from Microsoft and eMedia Communications. - bdn
//
// 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_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
// is_os2
// is_mac, is_mac68k, is_macppc

// is_linux, is_sco, is_unixware, is_mpras, is_reliant
// is_dec, is_sinix, is_freebsd, is_bsd
// is_vms
// (6) Windows Media Player version number (versions 6.4 and newer):
// is_WMP, is_WMP64, is_WMP7up, is_WMP7, is_WMP71, is_WMP8, is_WMP9
// is_WMP71up, is_WMP8up, is_WMP9up
// is_WMPMajor (integer indicating major player version number: 6, 7, 8 ...)
// is_WMPMinor (float indicating full player version number: 6.4, 7.0, 7.1 ...)

// based in part on
// http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html
// The Ultimate JavaScript Client Sniffer
// and Andy King's object detection sniffer
//
// 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. 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.
