// (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_opera2, is_opera3, is_opera4, is_opera5, is_opera5up
// (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
