release, so it's worth checking back even after reading earlier versions.

New packaging infrastructure

The standard library's packaging infrastructure has been updated to adopt

some of the features developed by the wider community.

* the :mod:`packaging` package and ``pysetup`` script (inspired by

``setuptools``, ``distribute``, ``distutil2`` and ``pip``)

* the :mod:`venv` module and ``pyvenv`` script (inspired by ``virtualenv``)

(Note: at time of writing, :pep:`405` is accepted, but not yet implemented)

* native support for package directories that don't require ``__init__.py``

marker files and can automatically span multiple path segments

(inspired by various third party approaches to namespace packages, as

described in :pep:`420`)
