//
//	The script returns a set of browser variables:
//
//      var	returns 	Description
//
//      ie	 	Internet Explorer 4+ and IE-based third-party browsers. You can also be more specific:
//      ie4	 	... Internet Explorer 4 only.
//      ie5	 	... Internet Explorer 5 or 6.
//      ie6	 	... Internet Explorer 6 only.
//      ie7	 	... Internet Explorer 7 only.
//
//
//      ns4	 	Netscape 4
//
//
//      ns6	 	Gecko and KDE-based browsers - which includes Netscape 6 and 7, Mozilla, Konqueror and Safari. You can also identify smaller groups within this:
//      ns7	 	... Netscape 7.
//      mz7	 	... any gecko browser except Netscape. This is principally designed to identify Mozilla's own builds from Version 0.6 onwards, but it also returns true for any other non-netscape gecko browser.
//      kde	 	... Konqueror, from KDE 2.2 onwards.
//      saf	 	... Safari. This variable will identify Safari irrespective of which browser it's set to identify as.
//
//      op5	 	Opera 5
//      op6	 	Opera 6
//      op7	 	Opera 7
//
//      These variables will identify Opera irrespective of which browser it's set to identify as.
//
// 	Underpinning these is a safety variable, for protecting legacy browsers:
//
//
//      for excluding a browser or an OS, use: exclude
//
// There are also three OS variables:
//
//
//      win	 	Windows
//      mac	 	Mac OS
//      lin	 	Linux, or anything else
//
// and you can query a lower-case version of the user agent string:
//
//
//      agt	mozilla/5.0 (windows; u; windows nt 5.1; en-us; rv:1.7.8) gecko/20050511 firefox/1.0.4
//
//	The sniffer variables are global, and therefore available to any other scripts on the same page. They allow you to code for or exclude specific browsers, eg:
//  if (mac&&ie5) { ... internet explorer 5 on a mac ... }
// if (!ns4) { ... not netscape 4 ... }
// if (win&&(op5||op6)) { ... a windows version of opera 5 or 6 ... }
// if (ie5||ns6||op7) { ... ie5+, gecko, kde or opera 7 ... }
//	Remember that some browsers return true for more than one variable:
//
//    * Explorer 6 returns true for (ie6) and also for (ie)
//    * Explorer 5 or 6 return true for (ie5) and also for (ie)
//    * Explorer 4 returns true for (ie4) and also for (ie)
//    * Konqueror returns true for (kde) and also for (ns6)
//    * Safari returns true for (saf) and also for (ns6)
//    * All Gecko-based browsers which aren't Netscape return true for (mz7) and also for (ns6)
//
//	The exclude variable returns true for all unspecified browsers. This is very useful for protecting them from scary DHTML, eg:
//	if (!exclude) { ... modern browsers only ... }
//	You may find it necessary to use a combination of expressions to get to the browser you need, eg:
//
//	if (!exclude) {
//    if (ns6||op7) { ... gecko, KTHML or Opera 7 ... }
//    else if (ie5) { ... internet explorer 5+ ... }
//    else { ... any other dhtml browser ... }
//    }
//	There are several minor browsers which have enough DHTML support to pass one of the object tests, but not enough to be useful.
//	The script specifically filters out (adds to the exclude group) - Espial Escape, ICEBrowser and OmniWeb.
