This library is a very thin wrapper around lib2to3 to utilize it to make Python 2 code more modern with the intention of eventually porting it over to Python 3.

The python-modernize command works like 2to3 <>_. Here's how you'd rewrite a
single file::

python-modernize -w

It does not guarantee, but it attempts to spit out a codebase compatible
with Python 2.6+ or Python 3. The code that it generates has a runtime
dependency on six <>_, unless the
--no-six option is used. Version 1.8.0 or later of six is
recommended. Some of the fixers output code that is not compatible with
Python 2.5 or lower.

Using this tool does not affect licensing of the modernized code.
