// (C) Netscape Communications 1999.  Permission granted to reuse and distribute.
// Revised 17 May 99 to add is.nav5up and is.ie5up (see below).
// Revised 21 Nov 00 to add is.gecko and is.ie5_5 Also Changed is.nav5 and is.nav5up to is.nav6 and is.nav6up
// Revised 22 Feb 01 to correct Javascript Detection for IE 5.x, Opera 4, 
//                      correct Opera 5 detection
//                      add support for winME and win2k
//                      synch with browser-type-oo.js
