Im not sure what your interest in having packaging support in your repo, but I was working on some stuff https://github.com/debugmonkey/python-salesforce and required this library. I packaged it up and sharing the initial code here. I haven't done extensive lintian testing yet and if you are interested I can pursue making this package suitable to be included in Debian and as a result Ubuntu as well. 

Please let me know if this interests you or not.

Thanks
Adam
