I am really glad you are interested in the packaging. Welcome! :)

Do you know how to build it from our svn? If not, feel free to ask.

Since python-sphinx 0.5 is in unstable now, do you think we should
build with the docs as they are in the debian packaging svn? I simply
used numpy svn and copied the doc directory into the tarball, see the
debian/rules.

I think it could probably be just removed, unless someone objects.

Thanks for the tip --- I think there was some reason for this
conflict, but I can't remember now. Let's wait a bit what other think
here.
