Thanks for getting involved!

A few minor queries, mostly down to my ignorance of Debian packaging:

• debian/changelog: Library versions are normally like "6.0.0" not "6.00".
• debian/copyright: Date range should probably be 2009-2014 (and I should update the code similarly -- as should upstream!)
• Does this packaging allow use from python3.x? And does it end up being an arch-specific package or _all.deb ?

Otherwise looks good.

version number is the upstream version number. So I have fixed this to match the lib number. Thanks for pointing this out.
Copyright year was simply taken over from the License file. I have bumped this to 2014.
Packaging is currently done using Python 2 only, to be compatible with Debian Wheezy (stable). The new build system (pybuild) for Python 2 and Python 3 is only available in unstable. If you switch to pybuild, you will not be able to build for Debian Wheezy (stable), since pybuild is not available in Wheezy.
I can switch to pybuild later, to make sure Python 3 support will be in next Debian release Jessie.
Package is architecture independent (_all.deb).
