Re: Problems downloading PG titles without a web browser

Daniel,

Thanks for your tips.  I was able to add a user agent string like this:

OLPCReader/1.0; +mailto:[email protected]

and that fixed the problem.  The code has been committed to Git and I'll
release a new .xo file shortly.

I don't know that I'll submit a path for network.py as the user agent
string is not a problem for most uses.
