contextlib2 is a backport of the `standard library's contextlib
module <https://docs.python.org/3.5/library/contextlib.html>`_ to
earlier Python versions.
It also serves as a real world proving ground for possible future
enhancements to the standard library version.
Development
-----------
contextlib2 has no runtime dependencies, but requires ``unittest2`` for testing
on Python 2.x, as well as ``setuptools`` and ``wheel`` to generate universal
wheel archives.
Local testing is just a matter of running ``python test_contextlib2.py``.
You can test against multiple versions of Python with
`tox <https://tox.testrun.org/>`_::
pip install tox
tox
Versions currently tested in both tox and Travis CI are:
* CPython 2.7
* CPython 3.4
* CPython 3.5
* CPython 3.6
* CPython 3.7
* PyPy
* PyPy3
