Description: Introduction

        d2to1 (the 'd' is for 'distutils') allows using distutils2-like setup.cfg files
        for a package's metadata with a distribute/setuptools setup.py script.  It
        works by providing a distutils2-formatted setup.cfg file containing all of a
        package's metadata, and a very minimal setup.py which will slurp its arguments
        from the setup.cfg.
        
        Note: distutils2 has been merged into the CPython standard library, where it is
        now known as 'packaging'.  This project was started before that change was
        finalized.  So all references to distutils2 should also be assumed to refer to
        packaging.
        
        Rationale
        ===========
        I'm currently in the progress of redoing the packaging of a sizeable number of
        projects.  I wanted to use distutils2-like setup.cfg files for all these
        projects, as they will hopefully be the future, and I much prefer them overall
        to using an executable setup.py.  So forward-support for distutils2 is
        appealing both as future-proofing, and simply the aesthetics of using a flat text file to describe a project's metadata.
        
        However, I did not want any of these projects to require distutils2 for
        installation yet--it is too unstable, and not widely installed.  So projects
        should still be installable using the familiar `./setup.py install`, for
        example.  Furthermore, not all use cases required by some of the packages I
        support are fully supported by distutils2 yet.  Hopefully they will be
        eventually, either through the distutils2 core or through extensions.  But in
        the meantime d2to1 will try to keep up with the state of the art and "best
        practices" for distutils2 distributions, while adding support in areas that
        it's lacking.
        
        Usage
        =======
        d2to1 requires a distribution to use distribute or setuptools.  Your
        distribution must include a distutils2-like setup.cfg file, and a minimal
        setup.py script.  For details on writing the setup.cfg, see the `distutils2
        documentation`_.  A simple sample can be found in d2to1's own setup.cfg (it
        uses its own machinery to install itself)::
        
        [metadata]
        name = d2to1
        version = 0.1.1

        setup
        distutils
        [files]
        packages = d2to1
        
        The minimal setup.py should look something like this::
        
        #!/usr/bin/env python
        
        try:
        from setuptools import setup
        except ImportError:
        from distribute_setup import use_setuptools
        use_setuptools()
        from setuptools import setup
        
        setup(
        setup_requires=['d2to1'],
        d2to1=True
        )
        
        Note that it's important to specify d2to1=True or else the d2to1 functionality
        will not be enabled.  It is also possible to set d2to1='some_file.cfg' to
        specify the (relative) path of the setup.cfg file to use.  But in general this
        functionality should not be necessary.
        
        It should also work fine if additional arguments are passed to `setup()`,
        but it should be noted that they will be clobbered by any options in the
        setup.cfg file.
        
        Caveats
        =========
        - The requires-dist option in setup.cfg is implemented through the
        distribute/setuptools install_requires option, rather than the broken
        "requires" keyword in normal distutils.
        - Not all features of distutils2 are supported yet.  If something doesn't seem
        to be working, it's probably not implemented yet.
        - Does not support distutils2 resources, and probably won't since it relies
        heavily on the sysconfig module only available in Python 3.2 and up.  This is
        one area in which d2to1 should really be seen as a transitional tool.  I
        don't really want to include a backport like distutils2 does.  In the
        meantime, package_data and data_files may still be used under the [files]
        section of setup.cfg.

        Changes
        =========
        
        
        0.2.11 (2013-08-29)
        -------------------
        
        - Replaced ``distribute_setup.py`` with ``ez_setup.py`` in order to bootstrap
        with modern setuptools when necessary.
        
        - Fixed a couple minor Python 3-specific issues. In particular the
        ``data_files`` option could be passed to ``setup()`` as a ``dict_items``
        object instead of a ``list`` which is what would normally be expected.
        
        - Added a tox.ini (frankly I thought there already was one).
        
        
        0.2.10 (2013-04-10)
        -------------------
        
        - Added support for the ``setup-requires-dist`` option in the ``[metadata]``
        section of setup.cfg.  This is analogous to the Setup-Requires-Dist metadata
        field supported by PEP-426 and uses the ``setup_requires`` argument to
        setuptools' ``setup()`` to implement it.
        
        - Added support for the ``dependency_links`` and ``include_package_data``
        arguments to setuptools' ``setup()`` in the ``[backwards_compat]`` section of
        setup.cfg.
        
        - When a setup_hook calls sys.exit() don't show a traceback for the
        SystemExit exception.
        
        - Fixed a bug in the exception formatting when exceptions occur in setup.cfg
        handling.
        
        
        0.2.9 (2013-03-05)
        ------------------
        
        - Fixed a bug in the extra-files supported added in 0.2.8.  Makes sure that
        monkey-patches can't be installed more than once and that the log
        reference is properly encapsulated.
        
        
        0.2.8 (2013-03-05)
        ------------------
        
        - Improved handling of packages where the packages_root option is set. That is,
        the Python package is not directly in the root of the source tree, but is in
        some sub-directory.  Now the packages_root directory is prepended to
        sys.path while processing the setup.cfg and running setup hooks.
        
        - Added support for the Keywords metadata field via the keywords option in the
        ``[metadata]`` section of setup.cfg.
        
        - Fixed a missing import that caused a misleading exception when setup.cfg is
        missing.
        
        - Upgraded the shipped distribute_setup.py to the latest for distribute 0.6.28
        
        - Added a few basic functional tests, along with an infrastructure to add more
        as needed.  They can be run with nose and possibly with py.test though the
        latter hasn't been tested.
        
        - Improved hook imports to work better with namespace packages.
        
        - Added support for the extra_files option of the ``[files]`` section in
        setup.cfg.  This was a feature from distutils2 that provided an alternative
        to MANIFEST.in for including additional files in source distributions (it
        does not yet support wildcard patterns but maybe it should?)
        
        - Added support for the tests_require setup argument from setuptools via
        the [backwards_compat] section in setup.cfg.
        
        - Supports Python 3 natively without 2to3.  This makes Python 3 testing of
        d2to1 easier to support.
        
        
        0.2.7 (2012-02-20)
        ------------------
        
        - If no extension modules or entry points are defined in the setup.cfg, don't
        clobber any extension modules/entry points that may be defined in setup.py.
        
        
        0.2.6 (2012-02-17)
        ------------------
        
        - Added support for setuptools entry points in an ``[entry_points]`` section of
        setup.cfg--this is just for backwards-compatibility purposes, as
        packaging/distutils2 does not yet have a standard replacement for the entry
        points system.
        
        - Added a [backwards_compat] section for setup.cfg for other options that are
        supported by setuptools/distribute, but that aren't part of the distutils2
        standard.  So far the only options supported here are zip_safe and use_2to3.
        (Note: packaging does support a use-2to3 option to the build command, but if
        we tried to use that, distutils would not recognize it as a valid build
        option.)
        
        - Added support for the new (and presumably final) extension section format
        used by packaging.  In this format, extensions should be specified in config
        sections of the format ``[extension: ext_mod_name]``, where any whitespace is
        optional.  The old format used an ``=`` instead of ``:`` and is still
        supported, but should be considered deprecated.
        
        - Added support for the new syntax used by packaging for the package_data
        option (which is deprecated in packaging in favor of the resources system,
        but still supported).  The new syntax is like::
        
        package_data =
        packagename = pattern1 pattern2 pattern3
        packagename.subpack =
        pattern1
        pattern2
        pattern3
        
        That is, after ``package_data =``, give the name of a package, followed by
        an ``=``, followed by any number of whitespace separated wildcard patterns (or
        actual filenames relative to the package).  Under this scheme, whitespace is
        not allowed in the patterns themselves.
        
        
        0.2.5 (2011-07-21)
        ------------------
        
        - Made the call to pkg_resources.get_distribution() to set __version__ more
        robust, so that it doesn't fail on, for example, VersionConflict errors
        
        
        0.2.4 (2011-07-05)
        ------------------
        
        - Fixed some bugs with installation on Python 3
        
        
        0.2.3 (2011-06-23)
        ------------------
        
        - Renamed 'setup_hook' to 'setup_hooks' as is now the case in the packaging
        module.  Added support for multiple setup_hooks
        
        
        0.2.2 (2011-06-15)
        ------------------
        
        - Fixed a bug in DefaultGetDict where it didn't actually save the returned
        default in the dictionary--so any command options would get lost
        - Fixed a KeyError when the distribution does not have any custom commands
        specified
        
        
        0.2.1 (2011-06-15)
        ------------------
        
        - Reimplemented command hooks without monkey-patching and more reliably in
        general (though it's still a flaming hack).  The previous monkey patch-based
        solution would break if d2to1 were entered multiple times, which could happen
        in some scenarios
        
        
        0.2.0 (2011-06-14)
        ------------------
        
        - Version bump to start using micro-version numbers for bug fixes only, now
        that the my primary feature goals are complete
        
        
        0.1.5 (2011-06-02)
        ------------------
        
        - Adds support for the data_files option under [files].  Though this is
        considered deprecated and may go away at some point, it can be useful in the
        absence of resources support
        - Adds support for command pre/post-hooks.  Warning: this monkey-patches
        distutils.dist.Distribution a little bit... :(
        - Adds (slightly naive) support for PEP 345-style version specifiers in
        requires-dist (environment markers not supported yet)
        - Fixed a bug where not enough newlines were inserted between description files
        
        
        0.1.4 (2011-05-24)
        ------------------
        
        - Adds support for custom command classes specified in the 'commands' option
        under the [global] section in setup.cfg
        - Adds preliminary support for custom compilers specified in the 'compilers'
        option under the [global] section in setup.cfg.  This functionality doesn't
        exist in distutils/setuptools/distribute, so adding support for it is a
        flaming hack.  It hasn't really been tested beyond seeing that the custom
        compilers come up in `setup.py build_ext --help-compiler`, so any real-world
        testing of this feature would be appreciated
        
        
        0.1.3 (2011-04-20)
        ------------------
        
        - Adds zest.releaser entry points for updating the version number in a
        setup.cfg file; only useful if you use zest.releaser--otherwise harmless
        (might eventually move this functionality out into a separate product)
        - Though version 0.1.2 worked in Python3, use_2to3 wasn't added to the setup.py
        so 2to3 had to be run manually
        - Fixed a crash on projects that don't have a description-file option
        
        0.1.2 (2011-04-13)
        ------------------
        
        - Fixed the self-installation--it did not work if a d2to1 version was not
        already installed, due to the use of `pkg_resources.require()`
        - Adds nominal Python3 support
        - Fixes the 'classifier' option in setup.cfg
        
        0.1.1 (2011-04-12)
        ------------------
        
        - Fixed an unhelpful error message when a setup_hook fails to import
        - Made d2to1 able to use its own machinery to install itself
