Notice that binding to Python 2 may not be enough: you also need to
specify the Python 2 version (i.e. different bindings for 2.5, 2.6, and
2.7, say). You will have to ship different copies of the binding. Of
course, you can ship them in a single distribution (zip file, or
whatever your distribution format is).

If you are creating different copies of the binding, supporting both
2.x and 3.x simultaneously will be straight-forward.
