Python Wrapper for Google AJAX Language API ...

A Python Wrapper for Google AJAX Language API, Uses Google Language Detection, in cases source language is not provided with the source text, Splits up text if it is longer then 4500 characters, as a limit put up by the API. Working fine for me, please let me know if i missed something.
