the arguments passed to the :func:`setup` function.

Checking a package
==================
The ``check`` command allows you to verify if your package meta-data
meet the minimum requirements to build a distribution.
To run it, just call it using your :file:`setup.py` script. If something is
missing, ``check`` will display a warning.
Let's take an example with a simple script::
from distutils.core import setup
setup(name='foobar')
Running the ``check`` command will display some warnings::
$ python setup.py check
running check
warning: check: missing required meta-data: version, url
warning: check: missing meta-data: either (author and author_email) or
(maintainer and maintainer_email) must be supplied
If you use the reStructuredText syntax in the ``long_description`` field and
`docutils <http://docutils.sourceforge.net/>`_ is installed you can check if
the syntax is fine with the ``check`` command, using the ``restructuredtext``
option.
For example, if the :file:`setup.py` script is changed like this::
from distutils.core import setup
desc = """\
My description
=============
This is the description of the ``foobar`` package.
"""
setup(name='foobar', version='1', author='tarek',
author_email='tarek@ziade.org',
url='http://example.com', long_description=desc)
Where the long description is broken, ``check`` will be able to detect it
by using the :mod:`docutils` parser::
$ pythontrunk setup.py check --restructuredtext
running check
warning: check: Title underline too short. (line 2)
warning: check: Could not finish the parsing.
.. _reading-metadata:
Reading the metadata
====================
The :func:`distutils.core.setup` function provides a command-line interface
that allows you to query the metadata fields of a project through the
:file:`setup.py` script of a given project::
$ python setup.py --name
distribute
This call reads the ``name`` metadata by running the
:func:`distutils.core.setup` function. Although, when a source or binary
distribution is created with Distutils, the metadata fields are written
in a static file called :file:`PKG-INFO`. When a Distutils-based project is
installed in Python, the :file:`PKG-INFO` file is copied alongside the modules
and packages of the distribution under :file:`NAME-VERSION-pyX.X.egg-info`,
where ``NAME`` is the name of the project, ``VERSION`` its version as defined
in the Metadata, and ``pyX.X`` the major and minor version of Python like
``2.7`` or ``3.2``.
You can read back this static file, by using the
:class:`distutils.dist.DistributionMetadata` class and its
:func:`read_pkg_file` method::
>>> from distutils.dist import DistributionMetadata
>>> metadata = DistributionMetadata()
>>> metadata.read_pkg_file(open('distribute-0.6.8-py2.7.egg-info'))
>>> metadata.name
'distribute'
>>> metadata.version
'0.6.8'
>>> metadata.description
'Easily download, build, install, upgrade, and uninstall Python packages'
Notice that the class can also be instanciated with a metadata file path to
loads its values::
>>> pkg_info_path = 'distribute-0.6.8-py2.7.egg-info'
>>> DistributionMetadata(pkg_info_path).name
'distribute'

It accepts 2-tuples ``("message regexp", WarningCategory)`` as positional

argument ``quiet`` is :const:`False`, it checks if the warnings are

On entry to the context manager, a :class:`WarningRecorder` instance is

PEP 389: The argparse Module for Parsing Command Lines
======================================================
XXX write this section.
The :mod:`argparse` module for parsing command-line arguments was
added, intended as a more powerful replacement for the
:mod:`optparse` module.
This means Python now supports three different modules for parsing
command-line arguments: :mod:`getopt`, :mod:`optparse`, and
:mod:`argparse`. The :mod:`getopt` module closely resembles the C
:cfunc:`getopt` function, so it remains useful if you're writing a
Python prototype that will eventually be rewritten in C.
:mod:`optparse` becomes redundant, but there are no plans to remove it
because there are many scripts still using it, and there's no
automated way to update these scripts. (Making the :mod:`argparse`
API consistent with :mod:`optparse`'s interface was discussed but
rejected as too messy and difficult.)
To summarize, if you're writing a new script and don't need to worry
about compatibility with earlier versions of Python, use
:mod:`argparse` instead of :mod:`optparse`.

A new environment variable, :envvar:`PYTHONWARNINGS`,
allows controlling warnings. It should be set to a string
containing warning settings, equivalent to those
used with the :option:`-W` switch, separated by commas.
(Contributed by Brian Curtin; :issue:`7301`.)
For example, the following setting will print warnings every time
they occur, but turn warnings from the :mod:`Cookie` module into an
error. (The exact syntax for setting an environment variable varies
across operating systems and shells, so it may be different for you.)

Distutils Enhancements
---------------------------------
XXX all of this work has been moved to Distutils2
XXX Not sure what we should say here
Distutils is being more actively developed, thanks to Tarek Ziadé
who has taken over maintenance of the package, so there are a number
of fixes and improvements.
A new :file:`setup.py` subcommand, ``check``, will check that the
arguments being passed to the :func:`setup` function are complete
and correct (:issue:`5732`).
Byte-compilation by the ``install_lib`` subcommand is now only done
if the ``sys.dont_write_bytecode`` setting allows it (:issue:`7071`).
:func:`distutils.sdist.add_defaults` now uses
*package_dir* and *data_files* to create the MANIFEST file.
:mod:`distutils.sysconfig` now reads the :envvar:`AR` and
:envvar:`ARFLAGS` environment variables.
.. ARFLAGS done in #5941
It is no longer mandatory to store clear-text passwords in the
:file:`.pypirc` file when registering and uploading packages to PyPI. As long
as the username is present in that file, the :mod:`distutils` package will
prompt for the password if not present. (Added by Tarek Ziadé,
based on an initial contribution by Nathan Van Gheem; :issue:`4394`.)
A Distutils setup can now specify that a C extension is optional by
setting the *optional* option setting to true. If this optional is
supplied, failure to build the extension will not abort the build
process, but instead simply not install the failing extension.
(Contributed by Georg Brandl; :issue:`5583`.)
The :class:`distutils.dist.DistributionMetadata` class'
:meth:`read_pkg_file` method will read the contents of a package's
:file:`PKG-INFO` metadata file. For an example of its use, see
:ref:`reading-metadata`.
(Contributed by Tarek Ziadé; :issue:`7457`.)
:file:`setup.py` files will now accept a :option:`--no-user-cfg` switch
to skip reading the :file:`~/.pydistutils.cfg` file. (Suggested by
by Michael Hoffman, and implemented by Paul Winkler; :issue:`1180`.)
When creating a tar-format archive, the ``sdist`` subcommand now
allows specifying the user id and group that will own the files in the
archives using the :option:`--owner` and :option:`--group` switches
(:issue:`6516`).
