Python 2 and 2to3
=================
Included with Python since 2.6, 2to3_ tool (and :mod:`lib2to3` module) helps
with porting Python 2 to Python 3 by performing various source translations.
This is a perfect solution for projects which wish to branch their Python 3
code from their Python 2 codebase and maintain them as independent codebases.
You can even begin preparing to use this approach today by writing
future-compatible Python code which works cleanly in Python 2 in conjunction
with 2to3; all steps outlined below will work with Python 2 code up to the
point when the actual use of 2to3 occurs.

Use of 2to3 as an on-demand translation step at install time is also possible,
preventing the need to maintain a separate Python 3 codebase, but this approach
