- *
- * User Agents Sampled from: http://www.useragentstring.com/
- *
- * This implementation is based on the original work from Gary White
- * http://apptools.com/phptools/browser/
- *
- * Gary White noted: "Since browser detection is so unreliable, I am
- * no longer maintaining this script. You are free to use and or
- * modify/update it as you want, however the author assumes no
- * responsibility for the accuracy of the detected values."
- *
- * Anyone experienced with Gary's script might be interested in these notes:
