isSafari3 = isSafari && check(/version//3/),

isSafari4 = isSafari && check(/version//4/),

isIE7 = !isOpera && ua.indexOf("msie 7") > -1,

isIE8 = !isOpera && ua.indexOf("msie 8") > -1,

isGecko = !isSafari && !isChrome && ua.indexOf("gecko") > -1,

isGecko3 = isGecko && ua.indexOf("rv:1.9") > -1,

isBorderBox = isIE && !isStrict,

isWindows = (ua.indexOf("windows") != -1 || ua.indexOf("win32") != -1),

isMac = (ua.indexOf("macintosh") != -1 || ua.indexOf("mac os x") != -1),
