' Library Description:
'
' Here is the JavaScript code necessary to detect browser vendor, version number, 
' and operating system. This code creates a group of variables which indicate the 
' browser's vendor, version number, JavaScript version, and operating system. 
'
' This code is believed to be compatible with all versions of all JavaScript-
' capable browsers on all platforms. It has been tested on the following operating 
' systems and browser versions: 
'
' - Windows 2000/XP: Navigator 6, Navigator 7; 
'		Internet Explorer 5, Internet Explorer 6; 
' - Windows NT: Navigator 2, Navigator 3, Navigator 4, Navigator 6, Navigator 7; 
'		Internet Explorer 5; Internet Explorer 3; Opera 3 
' - Windows 95: Navigator 4; Internet Explorer 4 
' - Macintosh OS 9: Navigator 4, Navigator 6, Navigator 7; Internet Explorer 3.01, 
'		Internet Explorer 4.02 and Internet Explorer 5.2
' - Macintosh OS X: Navigator 6, Navigator 7; Internet Explorer 5.2; Safari 1.0
' - SunOS5: Navigator 3
