Erlang Blogger API is working !!!

I've finally manage to get it working !
The solution was in the AuthToken from my code, I didn't squeezed the final '\n' character !

Later when the http request was generated, headers were split, making the GFE returning 400 Bad Request.

This is the corrected 'extract_auth/1':

extract_auth(<<"Auth=", Rest/binary>>) ->
        Size = size(Rest) - 1,
        <<Auth:Size/binary, _/binary>> = Rest,
        {ok, Auth};

I squeeze the final character !

Here's a link to the google groups discussion.
