//
// 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

// 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_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

// versions. For DOM tests scripters commonly used the

// 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.
