ACK, that was my intention as is started to work on the piuparts code.
Bring in small changes to the py 2 codebase to make a transition to py3 easy in the long run.

What’s the test target and how can i use it?

With tox you can test agains multiple python versions. You define the versions you want to test agains in a file called “tox.ini".
Instead of calling “nosetests" you call the command “tox” which, in our case, calls nosetests with py34 and py27.

I think to start with a new py3 branch on your side is the way to go.
