// (1) browser vendor:
//     is.nav, is.ie, is.opera, is.hotjava, is.webtv, is.TVNavigator, is.AOLTV
// (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.nav6, is.nav6up, is.gecko, is.ie3, 
//     is.ie4, is.ie4up, is.ie5, is.ie5up, is.ie5_5, is.ie5_5up, is.ie6, is.ie6up, is.hotjava3, is.hotjava3up
// (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.winme, is.win2k
