I'm maintaining a configparser 3.2+ backport for 2.6-2.7 using 3to2. A fully automatic conversion is not really possible, partly because the 3to2 tool is not perfect, and partly because there are parts of the code (esp. in the tests) which no mechanical converter could have figured out on its own.

Anyway, the backport is available here:


There's some documentation there on the conversion process I came up with.

As for distutils2, I was already contacted by Éric Araujo and will help him improve 3to2. We are yet to contact its authors to see if they believe merging our changes upstream will be possible.
