//The script returns a set of browser variables (Below are live results dependant on your browser type):
//      var	returns 	Description
//     		
//      ie	0 	Internet Explorer 4+ and IE-based third-party browsers. You can also be more specific:
//      ie4	0 	... Internet Explorer 4 only.
//      ie5	0 	... Internet Explorer 5 or 6.
//      ie6	0 	... Internet Explorer 6 only.
//      ns4	0 	Netscape 4
//      ns6	1 	Gecko and KDE-based browsers - which includes Netscape 6 and 7, Mozilla, Konqueror and Safari. You can also identify smaller groups within this:
//      ns7	0 	... Netscape 7.
//      mz7	1 	... 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	0 	... Konqueror, from KDE 2.2 onwards.
//      saf	0 	... Safari. This variable will identify Safari irrespective of which browser it's set to identify as.
//      op5	0 	Opera 5
//      op6	0 	Opera 6
//      op7	0 	Opera 7
//
//Underpinning these is a safety variable, for protecting legacy browsers:
//      	
//      exclude	0 	
//
//There are also three OS variables:
//      		
//      win	1 	Windows
//      mac	0 	Mac OS
//      lin	0 	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:1.9b2) gecko/2007121120 firefox/3.0b2
