// Revised 17 May 99 to add is_nav5up and is_ie5up (see below).
// Everything yo always wanted to know about your Javascript client
// but were afraid to ask. Create "is_" variables indicating:
// (1) browser vendor:
// is_nav, is_ie, is_opera
// (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) broser vendor AND major version nunber
// is_nav2, is_nav3, is_nav4, is_nav4up, is_nav5, is_nav5up, is_ie3, is_ie4, is_ie4up
// (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_os2
// is_mac, is_mac68k, is_macppc
// is_unix
