The Net_UserAgent object does a number of tests on an HTTP user agent string. The results of these tests are available via methods of the object. This module is based upon the JavaScript browser detection code available at http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html. This module had many influences from the lib/Browser.php code in version 1.3 of Horde. WWW: http://pear.php.net/package/Net_UserAgent_Detect/
