The first small portion of the WebCore is documented and released as a taste of what's to come in the full library. The browser detector can be used as-is and implements an algorithm that is not at all PHP-specific (though the implementation is in PHP). There is full developer and public documentation included (also a taste of what the full WebCore documentation will look like). Check out <a href="http://www.earthli.com/software/">earthli Software</a> for more details.
