Re: Qahirah: A High-Level Cairo API Binding For Python 3

This looks really nice.

Is it generated automatically or did you write all this by hand?

Is there a reason you always have create() methods rather than making 
the object constructor take the arguments?

Do you know if it will work with Python < 3?
