+Installing Python projects: overwiew
+====================================

+
+Introduction
+============
+
+Although Python's extensive standard library covers many programming needs,
+there often comes a time when you need to add new functionality to your Python
+installation in the form of third-party modules. This might be necessary to
+support your own programming, or to support an application that you want to use
+and that happens to be written in Python.
+
+In the past, there was little support for adding third-party modules to an
+existing Python installation.  With the introduction of the Python Distribution
+Utilities (Distutils for short) in Python 2.0, this changed.  However, not all
+problems were solved; end-users had to rely on ``easy_install`` or
+``pip`` to download third-party modules from PyPI, uninstall distributions or do
+other maintenance operations.  Packaging is a more complete replacement for
+Distutils, in the standard library, with a backport named Distutils2 available
+for older Python versions.
+
+This document is aimed primarily at people who need to install third-party
+Python modules: end-users and system administrators who just need to get some
+Python application running, and existing Python programmers who want to add
+new goodies to their toolbox. You don't need to know Python to read this
+document; there will be some brief forays into using Python's interactive mode
+to explore your installation, but that's it. If you're looking for information
+on how to distribute your own Python modules so that others may use them, see
+the :ref:`packaging-index` manual.
+
+
+.. _packaging-trivial-install:
+
+Best case: trivial installation
+-------------------------------
+
+In the best case, someone will have prepared a special version of the module
+distribution you want to install that is targeted specifically at your platform
+and can be installed just like any other software on your platform. For example,
+the module's developer might make an executable installer available for Windows
+users, an RPM package for users of RPM-based Linux systems (Red Hat, SuSE,
+Mandrake, and many others), a Debian package for users of Debian and derivative
+systems, and so forth.
+
+In that case, you would use the standard system tools to download and install
+the specific installer for your platform and its dependencies.
+
+Of course, things will not always be that easy. You might be interested in a
+module whose distribution doesn't have an easy-to-use installer for your
+platform. In that case, you'll have to start with the source distribution
+released by the module's author/maintainer. Installing from a source
+distribution is not too hard, as long as the modules are packaged in the
+standard way. The bulk of this document addresses the building and installing
+of modules from standard source distributions.
+
+
+.. _packaging-distutils:
+
+The Python standard: Distutils
+------------------------------
+
+If you download a source distribution of a module, it will be obvious whether
+it was packaged and distributed using Distutils.  First, the distribution's name
+and version number will be featured prominently in the name of the downloaded
+archive, e.g. :file:`foo-1.0.tar.gz` or :file:`widget-0.9.7.zip`.  Next, the
+archive will unpack into a similarly-named directory: :file:`foo-1.0` or
+:file:`widget-0.9.7`.  Additionally, the distribution may contain a
+:file:`setup.cfg` file and a file named :file:`README.txt` ---or possibly just
+:file:`README`--- explaining that building and installing the module
+distribution is a simple matter of issuing the following command at your shell's
+prompt::
+
+   python setup.py install
+
+Third-party projects have extended Distutils to work around its limitations or
+add functionality.  After some years of near-inactivity in Distutils, a new
+maintainer has started to standardize good ideas in PEPs and implement them in a
+new, improved version of Distutils, called Distutils2 or Packaging.
+
+
+.. _packaging-new-standard:
+
+The new standard: Packaging
+---------------------------
+
+The rules described in the first paragraph above apply to Packaging-based
+projects too: a source distribution will have a name like
+:file:`widget-0.9.7.zip`.  One of the main differences with Distutils is that
+distributions no longer have a :file:`setup.py` script; it used to cause a
+number of issues.  Now there is a unique script installed with Python itself::
+
+   pysetup install widget-0.9.7.zip
+
+Running this command is enough to build and install projects (Python modules or
+packages, scripts or whole applications), without even having to unpack the
+archive.  It is also compatible with Distutils-based distributions.
+
+Unless you have to perform non-standard installations or customize the build
+process, you can stop reading this manual ---the above command is everything you
+need to get out of it.
+
+With :program:`pysetup`, you won't even have to manually download a distribution
+before installing it; see :ref:`packaging-pysetup`.
+
+
+.. _packaging-standard-install:
+
+Standard build and install
+==========================
+
+As described in section :ref:`packaging-new-standard`, building and installing
+a module distribution using Packaging usually comes down to one simple
+command::
+
+   pysetup run install_dist
+
+How you actually run this command depends on the platform and the command line
+interface it provides:
+
+* **Unix**: Use a shell prompt.
+* **Windows**: Open a command prompt ("DOS console") or use :command:`Powershell`.
+* **OS X**: Open a :command:`Terminal`.
+
+
+.. _packaging-platform-variations:
+
+Platform variations
+-------------------
+
+The setup command is meant to be run from the root directory of the source
+distribution, i.e. the top-level subdirectory that the module source
+distribution unpacks into. For example, if you've just downloaded a module
+source distribution :file:`foo-1.0.tar.gz` onto a Unix system, the normal
+steps to follow are these::
+
+   gunzip -c foo-1.0.tar.gz | tar xf -    # unpacks into directory foo-1.0
+   cd foo-1.0
+   pysetup run install_dist
+
+On Windows, you'd probably download :file:`foo-1.0.zip`. If you downloaded the
+archive file to :file:`C:\\Temp`, then it would unpack into
+:file:`C:\\Temp\\foo-1.0`. To actually unpack the archive, you can use either
+an archive manipulator with a graphical user interface (such as WinZip or 7-Zip)
+or a command-line tool (such as :program:`unzip`, :program:`pkunzip` or, again,
+:program:`7z`). Then, open a command prompt window ("DOS box" or
+Powershell), and run::
+
+   cd c:\Temp\foo-1.0
+   pysetup run install_dist
+
+
+.. _packaging-splitting-up:
+
+Splitting the job up
+--------------------
+
+Running ``pysetup run install_dist`` builds and installs all modules in one go. If you
+prefer to work incrementally ---especially useful if you want to customize the
+build process, or if things are going wrong--- you can use the setup script to
+do one thing at a time. This is a valuable tool when different users will perform
+separately the build and install steps. For example, you might want to build a
+module distribution and hand it off to a system administrator for installation
+(or do it yourself, but with super-user or admin privileges).
+
+For example, to build everything in one step and then install everything
+in a second step, you aptly invoke two distinct Packaging commands::
+
+   pysetup run build
+   pysetup run install_dist
+
+If you do this, you will notice that invoking the :command:`install_dist` command
+first runs the :command:`build` command, which ---in this case--- quickly
+notices it can spare itself the work, since everything in the :file:`build`
+directory is up-to-date.
+
+You may often ignore this ability to divide the process in steps if all you do
+is installing modules downloaded from the Internet, but it's very handy for
+more advanced tasks. If you find yourself in the need for distributing your own
+Python modules and extensions, though, you'll most likely run many individual
+Packaging commands.
+
+
+.. _packaging-how-build-works:
+
+How building works
+------------------
+
+As implied above, the :command:`build` command is responsible for collecting
+and placing the files to be installed into a *build directory*. By default,
+this is :file:`build`, under the distribution root. If you're excessively
+concerned with speed, or want to keep the source tree pristine, you can specify
+a different build directory with the :option:`--build-base` option. For example::
+
+   pysetup run build --build-base /tmp/pybuild/foo-1.0
+
+(Or you could do this permanently with a directive in your system or personal
+Packaging configuration file; see section :ref:`packaging-config-files`.)
+In the usual case, however, all this is unnecessary.
+
+The build tree's default layout looks like so::
+
+   --- build/ --- lib/
+   or
+   --- build/ --- lib.<plat>/
+                  temp.<plat>/
+
+where ``<plat>`` expands to a brief description of the current OS/hardware
+platform and Python version. The first form, with just a :file:`lib` directory,
+is used for pure module distributions (module distributions that
+include only pure Python modules). If a module distribution contains any
+extensions (modules written in C/C++), then the second form, with two ``<plat>``
+directories, is used. In that case, the :file:`temp.{plat}` directory holds
+temporary files generated during the compile/link process which are not intended
+to be installed. In either case, the :file:`lib` (or :file:`lib.{plat}`) directory
+contains all Python modules (pure Python and extensions) to be installed.
+
+In the future, more directories will be added to handle Python scripts,
+documentation, binary executables, and whatever else is required to install
+Python modules and applications.
+
+
+.. _packaging-how-install-works:
+
+How installation works
+----------------------
+
+After the :command:`build` command is run (whether explicitly or by the
+:command:`install_dist` command on your behalf), the work of the :command:`install_dist`
+command is relatively simple: all it has to do is copy the contents of
+:file:`build/lib` (or :file:`build/lib.{plat}`) to the installation directory
+of your choice.
+
+If you don't choose an installation directory ---i.e., if you just run
+``pysetup run install_dist``\ --- then the :command:`install_dist` command
+installs to the standard location for third-party Python modules. This location
+varies by platform and depending on how you built/installed Python itself. On
+Unix (and Mac OS X, which is also Unix-based), it also depends on whether the
+module distribution being installed is pure Python or contains extensions
+("non-pure"):
+
++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+

++=================+=====================================================+==================================================+=======+

++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
+
+Notes:
+
+(1)
+   Most Linux distributions include Python as a standard part of the system, so
+   :file:`{prefix}` and :file:`{exec-prefix}` are usually both :file:`/usr` on
+   Linux. If you build Python yourself on Linux (or any Unix-like system), the
+   default :file:`{prefix}` and :file:`{exec-prefix}` are :file:`/usr/local`.
+
+(2)
+   The default installation directory on Windows was :file:`C:\\Program
+   Files\\Python` under Python 1.6a1, 1.5.2, and earlier.
+
+:file:`{prefix}` and :file:`{exec-prefix}` stand for the directories that Python
+is installed to, and where it finds its libraries at run-time. They are always
+the same under Windows, and very often the same under Unix and Mac OS X. You
+can find out what your Python installation uses for :file:`{prefix}` and
+:file:`{exec-prefix}` by running Python in interactive mode and typing a few
+simple commands.
+
+.. TODO link to Doc/using instead of duplicating
+
+To start the interactive Python interpreter, you need to follow a slightly
+different recipe for each platform. Under Unix, just type :command:`python` at
+the shell prompt. Under Windows (assuming the Python executable is on your
+:envvar:`PATH`, which is the usual case), you can choose :menuselection:`Start --> Run`,
+type ``python`` and press ``enter``. Alternatively, you can simply execute
+:command:`python` at a command prompt ("DOS console" or Powershell).
+
+Once the interpreter is started, you type Python code at the prompt. For
+example, on my Linux system, I type the three Python statements shown below,
+and get the output as shown, to find out my :file:`{prefix}` and :file:`{exec-prefix}`::
+
+   Python 3.3 (r32:88445, Apr  2 2011, 10:43:54)
+   Type "help", "copyright", "credits" or "license" for more information.
+   >>> import sys
+   >>> sys.prefix
+   '/usr'
+   >>> sys.exec_prefix
+   '/usr'
+
+If you don't want to install modules to the standard location, or if you don't
+have permission to write there, then you need to read about alternate
+installations in section :ref:`packaging-alt-install`. If you want to customize your
+installation directories more heavily, see section :ref:`packaging-custom-install`.
+
+
+.. _packaging-alt-install:
+
+Alternate installation
+======================
+
+Often, it is necessary or desirable to install modules to a location other than
+the standard location for third-party Python modules. For example, on a Unix
+system you might not have permission to write to the standard third-party module
+directory. Or you might wish to try out a module before making it a standard
+part of your local Python installation. This is especially true when upgrading
+a distribution already present: you want to make sure your existing base of
+scripts still works with the new version before actually upgrading.
+
+The Packaging :command:`install_dist` command is designed to make installing module
+distributions to an alternate location simple and painless. The basic idea is
+that you supply a base directory for the installation, and the
+:command:`install_dist` command picks a set of directories (called an *installation
+scheme*) under this base directory in which to install files. The details
+differ across platforms, so read whichever of the following sections applies to
+you.
+
+
+.. _packaging-alt-install-prefix:
+
+Alternate installation: the home scheme
+---------------------------------------
+
+The idea behind the "home scheme" is that you build and maintain a personal
+stash of Python modules. This scheme's name is derived from the concept of a
+"home" directory on Unix, since it's not unusual for a Unix user to make their
+home directory have a layout similar to :file:`/usr/` or :file:`/usr/local/`.
+In spite of its name's origin, this scheme can be used by anyone, regardless
+of the operating system.
+
+Installing a new module distribution in this way is as simple as ::
+
+   pysetup run install_dist --home <dir>
+
+where you can supply any directory you like for the :option:`--home` option. On
+Unix, lazy typists can just type a tilde (``~``); the :command:`install_dist` command
+will expand this to your home directory::
+
+   pysetup run install_dist --home ~
+
+The :option:`--home` option defines the base directory for the installation.
+Under it, files are installed to the following directories:
+
++------------------------------+---------------------------+-----------------------------+
+| Type of file                 | Installation Directory    | Override option             |
++==============================+===========================+=============================+
+| pure module distribution     | :file:`{home}/lib/python` | :option:`--install-purelib` |
++------------------------------+---------------------------+-----------------------------+
+| non-pure module distribution | :file:`{home}/lib/python` | :option:`--install-platlib` |
++------------------------------+---------------------------+-----------------------------+
+| scripts                      | :file:`{home}/bin`        | :option:`--install-scripts` |
++------------------------------+---------------------------+-----------------------------+
+| data                         | :file:`{home}/share`      | :option:`--install-data`    |
++------------------------------+---------------------------+-----------------------------+
+
+
+.. _packaging-alt-install-home:
+
+Alternate installation: Unix (the prefix scheme)
+------------------------------------------------
+
+The "prefix scheme" is useful when you wish to use one Python installation to
+run the build command, but install modules into the third-party module directory
+of a different Python installation (or something that looks like a different
+Python installation). If this sounds a trifle unusual, it is ---that's why the
+"home scheme" comes first. However, there are at least two known cases where the
+prefix scheme will be useful.
+
+First, consider that many Linux distributions put Python in :file:`/usr`, rather
+than the more traditional :file:`/usr/local`. This is entirely appropriate,
+since in those cases Python is part of "the system" rather than a local add-on.
+However, if you are installing Python modules from source, you probably want
+them to go in :file:`/usr/local/lib/python2.{X}` rather than
+:file:`/usr/lib/python2.{X}`. This can be done with ::
+
+   pysetup run install_dist --prefix /usr/local
+
+Another possibility is a network filesystem where the name used to write to a
+remote directory is different from the name used to read it: for example, the
+Python interpreter accessed as :file:`/usr/local/bin/python` might search for
+modules in :file:`/usr/local/lib/python2.{X}`, but those modules would have to
+be installed to, say, :file:`/mnt/{@server}/export/lib/python2.{X}`. This could
+be done with ::
+
+   pysetup run install_dist --prefix=/mnt/@server/export
+
+In either case, the :option:`--prefix` option defines the installation base, and
+the :option:`--exec-prefix` option defines the platform-specific installation
+base, which is used for platform-specific files. (Currently, this just means
+non-pure module distributions, but could be expanded to C libraries, binary
+executables, etc.) If :option:`--exec-prefix` is not supplied, it defaults to
+:option:`--prefix`. Files are installed as follows:
+
++------------------------------+-----------------------------------------------------+-----------------------------+
+| Type of file                 | Installation Directory                              | Override option             |
++==============================+=====================================================+=============================+
+| pure module distribution     | :file:`{prefix}/lib/python{X.Y}/site-packages`      | :option:`--install-purelib` |
++------------------------------+-----------------------------------------------------+-----------------------------+
+| non-pure module distribution | :file:`{exec-prefix}/lib/python{X.Y}/site-packages` | :option:`--install-platlib` |
++------------------------------+-----------------------------------------------------+-----------------------------+
+| scripts                      | :file:`{prefix}/bin`                                | :option:`--install-scripts` |
++------------------------------+-----------------------------------------------------+-----------------------------+
+| data                         | :file:`{prefix}/share`                              | :option:`--install-data`    |
++------------------------------+-----------------------------------------------------+-----------------------------+
+
+There is no requirement that :option:`--prefix` or :option:`--exec-prefix`
+actually point to an alternate Python installation; if the directories listed
+above do not already exist, they are created at installation time.
+
+Incidentally, the real reason the prefix scheme is important is simply that a
+standard Unix installation uses the prefix scheme, but with :option:`--prefix`
+and :option:`--exec-prefix` supplied by Python itself as ``sys.prefix`` and
+``sys.exec_prefix``. Thus, you might think you'll never use the prefix scheme,
+but every time you run ``pysetup run install_dist`` without any other
+options, you're using it.
+
+Note that installing extensions to an alternate Python installation doesn't have
+anything to do with how those extensions are built: in particular, extensions
+will be compiled using the Python header files (:file:`Python.h` and friends)
+installed with the Python interpreter used to run the build command. It is
+therefore your responsibility to ensure compatibility between the interpreter
+intended to run extensions installed in this way and the interpreter used to
+build these same extensions. To avoid problems, it is best to make sure that
+the two interpreters are the same version of Python (possibly different builds,
+or possibly copies of the same build). (Of course, if your :option:`--prefix`
+and :option:`--exec-prefix` don't even point to an alternate Python installation,
+this is immaterial.)
+
+
+.. _packaging-alt-install-windows:
+
+Alternate installation: Windows (the prefix scheme)
+---------------------------------------------------
+
+Windows has a different and vaguer notion of home directories than Unix, and
+since its standard Python installation is simpler, the :option:`--prefix` option
+has traditionally been used to install additional packages to arbitrary
+locations. ::
+
+   pysetup run install_dist --prefix "\Temp\Python"
+
+to install modules to the :file:`\\Temp\\Python` directory on the current drive.
+
+The installation base is defined by the :option:`--prefix` option; the
+:option:`--exec-prefix` option is unsupported under Windows. Files are
+installed as follows:
+
++------------------------------+---------------------------+-----------------------------+
+| Type of file                 | Installation Directory    | Override option             |
++==============================+===========================+=============================+
+| pure module distribution     | :file:`{prefix}`          | :option:`--install-purelib` |
++------------------------------+---------------------------+-----------------------------+
+| non-pure module distribution | :file:`{prefix}`          | :option:`--install-platlib` |
++------------------------------+---------------------------+-----------------------------+
+| scripts                      | :file:`{prefix}\\Scripts` | :option:`--install-scripts` |
++------------------------------+---------------------------+-----------------------------+
+| data                         | :file:`{prefix}\\Data`    | :option:`--install-data`    |
++------------------------------+---------------------------+-----------------------------+
+
+
+.. _packaging-custom-install:
+
+Custom installation
+===================
+
+Sometimes, the alternate installation schemes described in section
+:ref:`packaging-alt-install` just don't do what you want. You might want to tweak
+just one or two directories while keeping everything under the same base
+directory, or you might want to completely redefine the installation scheme.
+In either case, you're creating a *custom installation scheme*.
+
+You probably noticed the column of "override options" in the tables describing
+the alternate installation schemes above. Those options are how you define a
+custom installation scheme. These override options can be relative, absolute,
+or explicitly defined in terms of one of the installation base directories.
+(There are two installation base directories, and they are normally the same
+---they only differ when you use the Unix "prefix scheme" and supply different
+:option:`--prefix` and :option:`--exec-prefix` options.)
+
+For example, say you're installing a module distribution to your home directory
+under Unix, but you want scripts to go in :file:`~/scripts` rather than
+:file:`~/bin`. As you might expect, you can override this directory with the
+:option:`--install-scripts` option and, in this case, it makes most sense to supply
+a relative path, which will be interpreted relative to the installation base
+directory (in our example, your home directory)::
+
+   pysetup run install_dist --home ~ --install-scripts scripts
+
+Another Unix example: suppose your Python installation was built and installed
+with a prefix of :file:`/usr/local/python`. Thus, in a standard installation,
+scripts will wind up in :file:`/usr/local/python/bin`. If you want them in
+:file:`/usr/local/bin` instead, you would supply this absolute directory for
+the :option:`--install-scripts` option::
+
+   pysetup run install_dist --install-scripts /usr/local/bin
+
+This command performs an installation using the "prefix scheme", where the
+prefix is whatever your Python interpreter was installed with ---in this case,
+:file:`/usr/local/python`.
+
+If you maintain Python on Windows, you might want third-party modules to live in
+a subdirectory of :file:`{prefix}`, rather than right in :file:`{prefix}`
+itself. This is almost as easy as customizing the script installation directory
+---you just have to remember that there are two types of modules to worry about,
+pure modules and non-pure modules (i.e., modules from a non-pure distribution).
+For example::
+
+   pysetup run install_dist --install-purelib Site --install-platlib Site
+
+.. XXX Nothing is installed right under prefix in windows, is it??
+
+The specified installation directories are relative to :file:`{prefix}`. Of
+course, you also have to ensure that these directories are in Python's module
+search path, such as by putting a :file:`.pth` file in :file:`{prefix}`. See
+section :ref:`packaging-search-path` to find out how to modify Python's search path.
+
+If you want to define an entire installation scheme, you just have to supply all
+of the installation directory options. Using relative paths is recommended here.
+For example, if you want to maintain all Python module-related files under
+:file:`python` in your home directory, and you want a separate directory for
+each platform that you use your home directory from, you might define the
+following installation scheme::
+
+   pysetup run install_dist --home ~ \
+       --install-purelib python/lib \
+       --install-platlib python/'lib.$PLAT' \
+       --install-scripts python/scripts \
+       --install-data python/data
+
+or, equivalently, ::
+
+   pysetup run install_dist --home ~/python \
+       --install-purelib lib \
+       --install-platlib 'lib.$PLAT' \
+       --install-scripts scripts \
+       --install-data data
+
+``$PLAT`` doesn't need to be defined as an environment variable ---it will also
+be expanded by Packaging as it parses your command line options, just as it
+does when parsing your configuration file(s). (More on that later.)
+
+Obviously, specifying the entire installation scheme every time you install a
+new module distribution would be very tedious. To spare you all that work, you
+can store it in a Packaging configuration file instead (see section
+:ref:`packaging-config-files`), like so::
+
+   [install_dist]
+   install-base = $HOME
+   install-purelib = python/lib
+   install-platlib = python/lib.$PLAT
+   install-scripts = python/scripts
+   install-data = python/data
+
+or, equivalently, ::
+
+   [install_dist]
+   install-base = $HOME/python
+   install-purelib = lib
+   install-platlib = lib.$PLAT
+   install-scripts = scripts
+   install-data = data
+
+Note that these two are *not* equivalent if you override their installation
+base directory when running the setup script. For example, ::
+
+   pysetup run install_dist --install-base /tmp
+
+would install pure modules to :file:`/tmp/python/lib` in the first case, and
+to :file:`/tmp/lib` in the second case. (For the second case, you'd probably
+want to supply an installation base of :file:`/tmp/python`.)
+
+You may have noticed the use of ``$HOME`` and ``$PLAT`` in the sample
+configuration file. These are Packaging configuration variables, which
+bear a strong resemblance to environment variables. In fact, you can use
+environment variables in configuration files on platforms that have such a notion, but
+Packaging additionally defines a few extra variables that may not be in your
+environment, such as ``$PLAT``. Of course, on systems that don't have
+environment variables, such as Mac OS 9, the configuration variables supplied by
+the Packaging are the only ones you can use. See section :ref:`packaging-config-files`
+for details.

+
+.. _packaging-search-path:
+
+Modifying Python's search path
+------------------------------
+
+When the Python interpreter executes an :keyword:`import` statement, it searches
+for both Python code and extension modules along a search path. A default value
+for this path is configured into the Python binary when the interpreter is built.
+You can obtain the search path by importing the :mod:`sys` module and printing
+the value of ``sys.path``. ::
+
+   $ python
+   Python 2.2 (#11, Oct  3 2002, 13:31:27)
+   [GCC 2.96 20000731 (Red Hat Linux 7.3 2.96-112)] on linux2
+   Type "help", "copyright", "credits" or "license" for more information.
+   >>> import sys
+   >>> sys.path
+   ['', '/usr/local/lib/python2.3', '/usr/local/lib/python2.3/plat-linux2',
+    '/usr/local/lib/python2.3/lib-tk', '/usr/local/lib/python2.3/lib-dynload',
+    '/usr/local/lib/python2.3/site-packages']
+   >>>
+
+The null string in ``sys.path`` represents the current working directory.
+
+The expected convention for locally installed packages is to put them in the
+:file:`{...}/site-packages/` directory, but you may want to choose a different
+location for some reason. For example, if your site kept by convention all web
+server-related software under :file:`/www`. Add-on Python modules might then
+belong in :file:`/www/python`, and in order to import them, this directory would
+have to be added to ``sys.path``. There are several ways to solve this problem.
+
+The most convenient way is to add a path configuration file to a directory
+that's already on Python's path, usually to the :file:`.../site-packages/`
+directory. Path configuration files have an extension of :file:`.pth`, and each
+line must contain a single path that will be appended to ``sys.path``. (Because
+the new paths are appended to ``sys.path``, modules in the added directories
+will not override standard modules. This means you can't use this mechanism for
+installing fixed versions of standard modules.)
+
+Paths can be absolute or relative, in which case they're relative to the
+directory containing the :file:`.pth` file. See the documentation of
+the :mod:`site` module for more information.
+
+A slightly less convenient way is to edit the :file:`site.py` file in Python's
+standard library, and modify ``sys.path``. :file:`site.py` is automatically
+imported when the Python interpreter is executed, unless the :option:`-S` switch
+is supplied to suppress this behaviour. So you could simply edit
+:file:`site.py` and add two lines to it::
+
+   import sys
+   sys.path.append('/www/python/')
+
+However, if you reinstall the same major version of Python (perhaps when
+upgrading from 3.3 to 3.3.1, for example) :file:`site.py` will be overwritten by
+the stock version. You'd have to remember that it was modified and save a copy
+before doing the installation.
+
+Alternatively, there are two environment variables that can modify ``sys.path``.
+:envvar:`PYTHONHOME` sets an alternate value for the prefix of the Python
+installation. For example, if :envvar:`PYTHONHOME` is set to ``/www/python``,
+the search path will be set to ``['', '/www/python/lib/pythonX.Y/',
+'/www/python/lib/pythonX.Y/plat-linux2', ...]``.
+
+The :envvar:`PYTHONPATH` variable can be set to a list of paths that will be
+added to the beginning of ``sys.path``. For example, if :envvar:`PYTHONPATH` is
+set to ``/www/python:/opt/py``, the search path will begin with
+``['/www/python', '/opt/py']``. (Note that directories must exist in order to
+be added to ``sys.path``; the :mod:`site` module removes non-existent paths.)
+
+Finally, ``sys.path`` is just a regular Python list, so any Python application
+can modify it by adding or removing entries.
+
+
+.. _packaging-config-files:
+
+Configuration files for Packaging
+=================================
+
+As mentioned above, you can use configuration files to store personal or site
+preferences for any option supported by any Packaging command. Depending on your
+platform, you can use one of two or three possible configuration files. These
+files will be read before parsing the command-line, so they take precedence over
+default values. In turn, the command-line will override configuration files.
+Lastly, if there are multiple configuration files, values from files read
+earlier will be overridden by values from files read later.
+
+.. XXX "one of two or three possible..." seems wrong info. Below always 3 files
+   are indicated in the tables.
+
+
+.. _packaging-config-filenames:
+
+Location and names of configuration files
+-----------------------------------------
+
+The name and location of the configuration files vary slightly across
+platforms. On Unix and Mac OS X, these are the three configuration files listed
+in the order they are processed:
+
++--------------+----------------------------------------------------------+-------+
+| Type of file | Location and filename                                    | Notes |
++==============+==========================================================+=======+
+| system       | :file:`{prefix}/lib/python{ver}/packaging/packaging.cfg` | \(1)  |
++--------------+----------------------------------------------------------+-------+
+| personal     | :file:`$HOME/.pydistutils.cfg`                           | \(2)  |
++--------------+----------------------------------------------------------+-------+
+| local        | :file:`setup.cfg`                                        | \(3)  |
++--------------+----------------------------------------------------------+-------+
+
+Similarly, the configuration files on Windows ---also listed in the order they
+are processed--- are these:
+
++--------------+-------------------------------------------------+-------+
+| Type of file | Location and filename                           | Notes |
++==============+=================================================+=======+
+| system       | :file:`{prefix}\\Lib\\packaging\\packaging.cfg` | \(4)  |
++--------------+-------------------------------------------------+-------+
+| personal     | :file:`%HOME%\\pydistutils.cfg`                 | \(5)  |
++--------------+-------------------------------------------------+-------+
+| local        | :file:`setup.cfg`                               | \(3)  |
++--------------+-------------------------------------------------+-------+
+
+On all platforms, the *personal* file can be temporarily disabled by
+means of the `--no-user-cfg` option.
+
+Notes:
+
+(1)
+   Strictly speaking, the system-wide configuration file lives in the directory
+   where Packaging is installed.
+
+(2)
+   On Unix, if the :envvar:`HOME` environment variable is not defined, the
+   user's home directory will be determined with the :func:`getpwuid` function
+   from the standard :mod:`pwd` module. Packaging uses the
+   :func:`os.path.expanduser` function to do this.
+
+(3)
+   I.e., in the current directory (usually the location of the setup script).
+
+(4)
+   (See also note (1).) Python's default installation prefix is
+   :file:`C:\\Python`, so the system configuration file is normally
+   :file:`C:\\Python\\Lib\\packaging\\packaging.cfg`.
+
+(5)
+   On Windows, if the :envvar:`HOME` environment variable is not defined,
+   :envvar:`USERPROFILE` then :envvar:`HOMEDRIVE` and :envvar:`HOMEPATH` will
+   be tried. Packaging uses the :func:`os.path.expanduser` function to do this.
+
+
+.. _packaging-config-syntax:
+
+Syntax of configuration files
+-----------------------------
+
+All Packaging configuration files share the same syntax. Options defined in
+them are grouped into sections, and each Packaging command gets its own section.
+Additionally, there's a ``global`` section for options that affect every command.
+Sections consist of one or more lines containing a single option specified as
+``option = value``.
+
+For example, here's a complete configuration file that forces all commands to
+run quietly by default::
+
+   [global]
+   verbose = 0
+
+If this was the system configuration file, it would affect all processing
+of any Python module distribution by any user on the current system. If it was
+installed as your personal configuration file (on systems that support them),
+it would affect only module distributions processed by you. Lastly, if it was
+used as the :file:`setup.cfg` for a particular module distribution, it would
+affect that distribution only.
+
+.. XXX "(on systems that support them)" seems wrong info
+
+If you wanted to, you could override the default "build base" directory and
+make the :command:`build\*` commands always forcibly rebuild all files with
+the following::
+
+   [build]
+   build-base = blib
+   force = 1
+
+which corresponds to the command-line arguments::
+
+   pysetup run build --build-base blib --force
+
+except that including the :command:`build` command on the command-line means
+that command will be run. Including a particular command in configuration files
+has no such implication; it only means that if the command is run, the options
+for it in the configuration file will apply. (This is also true if you run
+other commands that derive values from it.)
+
+You can find out the complete list of options for any command using the
+:option:`--help` option, e.g.::
+
+   pysetup run build --help
+
+and you can find out the complete list of global options by using
+:option:`--help` without a command::
+
+   pysetup run --help
+
+See also the "Reference" section of the "Distributing Python Modules" manual.
+
+.. XXX no links to the relevant section exist.
+
+
+.. _packaging-building-ext:
+
+Building extensions: tips and tricks
+====================================
+
+Whenever possible, Packaging tries to use the configuration information made
+available by the Python interpreter used to run `pysetup`.
+For example, the same compiler and linker flags used to compile Python will also
+be used for compiling extensions. Usually this will work well, but in
+complicated situations this might be inappropriate. This section discusses how
+to override the usual Packaging behaviour.
+
+
+.. _packaging-tweak-flags:
+
+Tweaking compiler/linker flags
+------------------------------
+
+Compiling a Python extension written in C or C++ will sometimes require
+specifying custom flags for the compiler and linker in order to use a particular
+library or produce a special kind of object code. This is especially true if the
+extension hasn't been tested on your platform, or if you're trying to
+cross-compile Python.
+
+.. TODO update to new setup.cfg
+
+In the most general case, the extension author might have foreseen that
+compiling the extensions would be complicated, and provided a :file:`Setup` file
+for you to edit. This will likely only be done if the module distribution
+contains many separate extension modules, or if they often require elaborate
+sets of compiler flags in order to work.
+
+A :file:`Setup` file, if present, is parsed in order to get a list of extensions
+to build. Each line in a :file:`Setup` describes a single module. Lines have
+the following structure::
+
+   module ... [sourcefile ...] [cpparg ...] [library ...]
+
+
+Let's examine each of the fields in turn.
+
+* *module* is the name of the extension module to be built, and should be a
+  valid Python identifier. You can't just change this in order to rename a module
+  (edits to the source code would also be needed), so this should be left alone.
+
+* *sourcefile* is anything that's likely to be a source code file, at least
+  judging by the filename. Filenames ending in :file:`.c` are assumed to be
+  written in C, filenames ending in :file:`.C`, :file:`.cc`, and :file:`.c++` are
+  assumed to be C++, and filenames ending in :file:`.m` or :file:`.mm` are assumed
+  to be in Objective C.
+
+* *cpparg* is an argument for the C preprocessor,  and is anything starting with
+  :option:`-I`, :option:`-D`, :option:`-U` or :option:`-C`.
+
+* *library* is anything ending in :file:`.a` or beginning with :option:`-l` or
+  :option:`-L`.
+
+If a particular platform requires a special library on your platform, you can
+add it by editing the :file:`Setup` file and running ``pysetup run build``.
+For example, if the module defined by the line ::
+
+   foo foomodule.c
+
+must be linked with the math library :file:`libm.a` on your platform, simply add
+:option:`-lm` to the line::
+
+   foo foomodule.c -lm
+
+Arbitrary switches intended for the compiler or the linker can be supplied with
+the :option:`-Xcompiler` *arg* and :option:`-Xlinker` *arg* options::
+
+   foo foomodule.c -Xcompiler -o32 -Xlinker -shared -lm
+
+The next option after :option:`-Xcompiler` and :option:`-Xlinker` will be
+appended to the proper command line, so in the above example the compiler will
+be passed the :option:`-o32` option, and the linker will be passed
+:option:`-shared`. If a compiler option requires an argument, you'll have to
+supply multiple :option:`-Xcompiler` options; for example, to pass ``-x c++``
+the :file:`Setup` file would have to contain ``-Xcompiler -x -Xcompiler c++``.
+
+Compiler flags can also be supplied through setting the :envvar:`CFLAGS`
+environment variable. If set, the contents of :envvar:`CFLAGS` will be added to
+the compiler flags specified in the  :file:`Setup` file.
+

+
+Using non-Microsoft compilers on Windows
+----------------------------------------
+

+
+
+Borland/CodeGear C++
+^^^^^^^^^^^^^^^^^^^^
+
+This subsection describes the necessary steps to use Packaging with the Borland
+C++ compiler version 5.5. First you have to know that Borland's object file
+format (OMF) is different from the format used by the Python version you can
+download from the Python or ActiveState Web site. (Python is built with
+Microsoft Visual C++, which uses COFF as the object file format.) For this
+reason, you have to convert Python's library :file:`python25.lib` into the
+Borland format. You can do this as follows:
+
+.. Should we mention that users have to create cfg-files for the compiler?
+.. see also http://community.borland.com/article/0,1410,21205,00.html
+
+::
+
+   coff2omf python25.lib python25_bcpp.lib
+
+The :file:`coff2omf` program comes with the Borland compiler. The file
+:file:`python25.lib` is in the :file:`Libs` directory of your Python
+installation. If your extension uses other libraries (zlib, ...) you have to
+convert them too.
+
+The converted files have to reside in the same directories as the normal
+libraries.
+
+How does Packaging manage to use these libraries with their changed names?  If
+the extension needs a library (eg. :file:`foo`) Packaging checks first if it
+finds a library with suffix :file:`_bcpp` (eg. :file:`foo_bcpp.lib`) and then
+uses this library. In the case it doesn't find such a special library it uses
+the default name (:file:`foo.lib`.) [#]_
+
+To let Packaging compile your extension with Borland, C++ you now have to
+type::
+
+   pysetup run build --compiler bcpp
+
+If you want to use the Borland C++ compiler as the default, you could specify
+this in your personal or system-wide configuration file for Packaging (see
+section :ref:`packaging-config-files`.)
+
+
+.. seealso::
+
+   `C++Builder Compiler <http://www.codegear.com/downloads/free/cppbuilder>`_
+      Information about the free C++ compiler from Borland, including links to the
+      download pages.
+
+   `Creating Python Extensions Using Borland's Free Compiler <http://www.cyberus.ca/~g_will/pyExtenDL.shtml>`_
+      Document describing how to use Borland's free command-line C++ compiler to build
+      Python.
+
+
+GNU C / Cygwin / MinGW
+^^^^^^^^^^^^^^^^^^^^^^
+
+This section describes the necessary steps to use Packaging with the GNU C/C++
+compilers in their Cygwin and MinGW distributions. [#]_ For a Python interpreter
+that was built with Cygwin, everything should work without any of these
+following steps.
+
+Not all extensions can be built with MinGW or Cygwin, but many can. Extensions
+most likely to not work are those that use C++ or depend on Microsoft Visual C
+extensions.
+
+To let Packaging compile your extension with Cygwin, you have to type::
+
+   pysetup run build --compiler=cygwin
+
+and for Cygwin in no-cygwin mode [#]_ or for MinGW, type::
+
+   pysetup run build --compiler=mingw32
+
+If you want to use any of these options/compilers as default, you should
+consider writing it in your personal or system-wide configuration file for
+Packaging (see section :ref:`packaging-config-files`.)
+
+Older Versions of Python and MinGW
+""""""""""""""""""""""""""""""""""
+The following instructions only apply if you're using a version of Python
+inferior to 2.4.1 with a MinGW inferior to 3.0.0 (with
+:file:`binutils-2.13.90-20030111-1`).
+
+These compilers require some special libraries. This task is more complex than
+for Borland's C++, because there is no program to convert the library. First
+you have to create a list of symbols which the Python DLL exports. (You can find
+a good program for this task at
+http://www.emmestech.com/software/pexports-0.43/download_pexports.html).
+
+.. I don't understand what the next line means. --amk
+   (inclusive the references on data structures.)
+
+::
+
+   pexports python25.dll > python25.def
+
+The location of an installed :file:`python25.dll` will depend on the
+installation options and the version and language of Windows. In a "just for
+me" installation, it will appear in the root of the installation directory. In
+a shared installation, it will be located in the system directory.
+
+Then you can create from these information an import library for gcc. ::
+
+   /cygwin/bin/dlltool --dllname python25.dll --def python25.def --output-lib libpython25.a
+
+The resulting library has to be placed in the same directory as
+:file:`python25.lib`. (Should be the :file:`libs` directory under your Python
+installation directory.)
+
+If your extension uses other libraries (zlib,...) you might have to convert
+them too. The converted files have to reside in the same directories as the
+normal libraries do.
+
+
+.. seealso::
+
+   `Building Python modules on MS Windows platform with MinGW <http://www.zope.org/Members/als/tips/win32_mingw_modules>`_

+
+
+.. rubric:: Footnotes
+
+.. [#] This also means you could replace all existing COFF-libraries with
+   OMF-libraries of the same name.

+Pysetup is a simple script that supports the following features:
+
+- install, remove, list, and verify Python packages;
+- search for available packages on PyPI or any *Simple Index*;
+- verify installed packages (md5sum, installed files, version).
+
+
+Finding out what's installed
+----------------------------
+
+Pysetup makes it easy to find out what Python packages are installed::
+
+   $ pysetup search virtualenv
+   virtualenv 1.6 at /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info
+
+   $ pysetup search --all
+   pyverify 0.8.1 at /opt/python3.3/lib/python3.3/site-packages/pyverify-0.8.1.dist-info
+   virtualenv 1.6 at /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info
+   wsgiref 0.1.2 at /opt/python3.3/lib/python3.3/wsgiref.egg-info
+   ...
+
+
+Installing a distribution
+-------------------------
+
+Pysetup can install a Python project from the following sources:
+
+- PyPI and Simple Indexes;
+- source directories containing a valid :file:`setup.py` or :file:`setup.cfg`;
+- distribution source archives (:file:`project-1.0.tar.gz`, :file:`project-1.0.zip`);
+- HTTP (http://host/packages/project-1.0.tar.gz).
+
+
+Installing from PyPI and Simple Indexes::
+
+   $ pysetup install project
+   $ pysetup install project==1.0
+
+Installing from a distribution source archive::
+
+   $ pysetup install project-1.0.tar.gz
+
+Installing from a source directory containing a valid :file:`setup.py` or
+:file:`setup.cfg`::
+
+   $ cd path/to/source/directory
+   $ pysetup install
+
+   $ pysetup install path/to/source/directory
+
+Installing from HTTP::
+
+   $ pysetup install http://host/packages/project-1.0.tar.gz
+
+
+Retrieving metadata
+-------------------
+
+You can gather metadata from two sources, a project's source directory or an
+installed distribution. The `pysetup metadata` command can retrieve one or
+more metadata fields using the `-f` option and a metadata field as the
+argument. ::
+
+   $ pysetup metadata virtualenv -f version -f name
+   Version:
+       1.6
+   Name:
+       virtualenv
+
+   $ pysetup metadata virtualenv --all
+   Metadata-Version:
+       1.0
+   Name:
+       virtualenv
+   Version:
+       1.6
+   Platform:
+       UNKNOWN
+   Summary:
+       Virtual Python Environment builder
+   ...
+
+.. seealso::
+
+   There are three metadata versions, 1.0, 1.1, and 1.2. The following PEPs
+   describe specifics of the field names, and their semantics and usage.  1.0
+   :PEP:`241`, 1.1 :PEP:`314`, and 1.2 :PEP:`345`
+
+
+Removing a distribution
+-----------------------
+
+You can remove one or more installed distributions using the `pysetup remove`
+command::
+
+   $ pysetup remove virtualenv
+   removing 'virtualenv':
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/dependency_links.txt
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/entry_points.txt
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/not-zip-safe
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/PKG-INFO
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/SOURCES.txt
+     /opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/top_level.txt
+   Proceed (y/n)? y
+   success: removed 6 files and 1 dirs
+
+The optional '-y' argument auto confirms, skipping the conformation prompt::
+
+  $ pysetup remove virtualenv -y
+
+
+Getting help
+------------
+
+All pysetup actions take the `-h` and `--help` options which prints the commands
+help string to stdout. ::
+
+   $ pysetup remove -h
+   Usage: pysetup remove dist [-y]
+      or: pysetup remove --help
+
+   Uninstall a Python package.
+
+   positional arguments:
+      dist  installed distribution name
+
+   optional arguments:
+      -y  auto confirm package removal
+
+Getting a list of all pysetup actions and global options::
+
+   $ pysetup --help
+   Usage: pysetup [options] action [action_options]
+
+   Actions:
+       run: Run one or several commands
+       metadata: Display the metadata of a project

+:mod:`packaging.command` --- Standard Packaging commands
+========================================================
+
+.. module:: packaging.command
+   :synopsis: Standard packaging commands.
+
+
+This subpackage contains one module for each standard Packaging command, such as
+:command:`build`  or :command:`upload`.  Each command is implemented as a
+separate module, with the command name as the name of the module and of the
+class defined therein.
+
+
+
+:mod:`packaging.command.cmd` --- Abstract base class for Packaging commands
+===========================================================================
+
+.. module:: packaging.command.cmd
+   :synopsis: Abstract base class for commands.
+
+
+This module supplies the abstract base class :class:`Command`.  This class is
+subclassed by the modules in the packaging.command subpackage.
+
+
+.. class:: Command(dist)
+
+   Abstract base class for defining command classes, the "worker bees" of the
+   Packaging.  A useful analogy for command classes is to think of them as
+   subroutines with local variables called *options*.  The options are declared
+   in :meth:`initialize_options` and defined (given their final values) in
+   :meth:`finalize_options`, both of which must be defined by every command
+   class.  The distinction between the two is necessary because option values
+   might come from the outside world (command line, config file, ...), and any
+   options dependent on other options must be computed after these outside
+   influences have been processed --- hence :meth:`finalize_options`.  The body
+   of the subroutine, where it does all its work based on the values of its
+   options, is the :meth:`run` method, which must also be implemented by every
+   command class.
+
+   The class constructor takes a single argument *dist*, a
+   :class:`~packaging.dist.Distribution` instance.
+
+
+Creating a new Packaging command
+--------------------------------
+
+This section outlines the steps to create a new Packaging command.
+
+.. XXX the following paragraph is focused on the stdlib; expand it to document
+   how to write and register a command in third-party projects
+
+A new command lives in a module in the :mod:`packaging.command` package. There
+is a sample template in that directory called :file:`command_template`.  Copy
+this file to a new module with the same name as the new command you're
+implementing.  This module should implement a class with the same name as the
+module (and the command).  So, for instance, to create the command
+``peel_banana`` (so that users can run ``setup.py peel_banana``), you'd copy
+:file:`command_template` to :file:`packaging/command/peel_banana.py`, then edit
+it so that it's implementing the class :class:`peel_banana`, a subclass of
+:class:`Command`.  It must define the following methods:
+
+.. method:: Command.initialize_options()
+
+   Set default values for all the options that this command supports.  Note that
+   these defaults may be overridden by other commands, by the setup script, by
+   config files, or by the command line.  Thus, this is not the place to code
+   dependencies between options; generally, :meth:`initialize_options`
+   implementations are just a bunch of ``self.foo = None`` assignments.
+
+
+.. method:: Command.finalize_options()
+
+   Set final values for all the options that this command supports. This is
+   always called as late as possible, i.e. after any option assignments from the
+   command line or from other commands have been done.  Thus, this is the place
+   to to code option dependencies: if *foo* depends on *bar*, then it is safe to
+   set *foo* from *bar* as long as *foo* still has the same value it was
+   assigned in :meth:`initialize_options`.
+
+
+.. method:: Command.run()
+
+   A command's raison d'etre: carry out the action it exists to perform,
+   controlled by the options initialized in :meth:`initialize_options`,
+   customized by other commands, the setup script, the command line, and config
+   files, and finalized in :meth:`finalize_options`.  All terminal output and
+   filesystem interaction should be done by :meth:`run`.
+
+
+Command classes may define this attribute:
+
+
+.. attribute:: Command.sub_commands
+
+   *sub_commands* formalizes the notion of a "family" of commands,
+   e.g. ``install_dist`` as the parent with sub-commands ``install_lib``,
+   ``install_headers``, etc.  The parent of a family of commands defines
+   *sub_commands* as a class attribute; it's a list of 2-tuples ``(command_name,
+   predicate)``, with *command_name* a string and *predicate* a function, a
+   string or ``None``.  *predicate* is a method of the parent command that
+   determines whether the corresponding command is applicable in the current
+   situation.  (E.g. ``install_headers`` is only applicable if we have any C
+   header files to install.)  If *predicate* is ``None``, that command is always
+   applicable.
+
+   *sub_commands* is usually defined at the *end* of a class, because
+   predicates can be methods of the class, so they must already have been
+   defined.  The canonical example is the :command:`install_dist` command.
+
+.. XXX document how to add a custom command to another one's subcommands

+:mod:`packaging.compiler` --- Compiler classes
+==============================================
+
+.. module:: packaging.compiler
+   :synopsis: Compiler classes to build C/C++ extensions or libraries.
+
+
+This subpackage contains an abstract base class representing a compiler and
+concrete implementations for common compilers.  The compiler classes should not
+be instantiated directly, but created using the :func:`new_compiler` factory
+function.  Compiler types provided by Packaging are listed in
+:ref:`packaging-standard-compilers`.
+
+
+Public functions
+----------------
+
+.. function:: new_compiler(plat=None, compiler=None, verbose=0, dry_run=0, force=0)
+
+   Factory function to generate an instance of some
+   :class:`~.ccompiler.CCompiler` subclass for the requested platform or
+   compiler type.
+
+   If no argument is given for *plat* and *compiler*, the default compiler type
+   for the platform (:attr:`os.name`) will be used: ``'unix'`` for Unix and
+   Mac OS X, ``'msvc'`` for Windows.
+
+   If *plat* is given, it must be one of ``'posix'``, ``'darwin'`` or ``'nt'``.
+   An invalid value will not raise an exception but use the default compiler
+   type for the current platform.
+
+   .. XXX errors should never pass silently; this behavior is particularly
+      harmful when a compiler type is given as first argument
+
+   If *compiler* is given, *plat* will be ignored, allowing you to get for
+   example a ``'unix'`` compiler object under Windows or an ``'msvc'`` compiler
+   under Unix.  However, not all compiler types can be instantiated on every
+   platform.
+
+
+.. function:: customize_compiler(compiler)
+
+   Do any platform-specific customization of a CCompiler instance.  Mainly
+   needed on Unix to plug in the information that varies across Unices and is
+   stored in CPython's Makefile.
+
+
+.. function:: gen_lib_options(compiler, library_dirs, runtime_library_dirs, libraries)
+
+   Generate linker options for searching library directories and linking with
+   specific libraries.  *libraries* and *library_dirs* are, respectively, lists
+   of library names (not filenames!) and search directories.  Returns a list of
+   command-line options suitable for use with some compiler (depending on the
+   two format strings passed in).
+
+
+.. function:: gen_preprocess_options(macros, include_dirs)
+
+   Generate C preprocessor options (:option:`-D`, :option:`-U`, :option:`-I`) as
+   used by at least two types of compilers: the typical Unix compiler and Visual
+   C++. *macros* is the usual thing, a list of 1- or 2-tuples, where ``(name,)``
+   means undefine (:option:`-U`) macro *name*, and ``(name, value)`` means
+   define (:option:`-D`) macro *name* to *value*.  *include_dirs* is just a list
+   of directory names to be added to the header file search path (:option:`-I`).
+   Returns a list of command-line options suitable for either Unix compilers or
+   Visual C++.
+
+
+.. function:: get_default_compiler(osname, platform)
+
+   Determine the default compiler to use for the given platform.
+
+   *osname* should be one of the standard Python OS names (i.e. the ones
+   returned by ``os.name``) and *platform* the common value returned by
+   ``sys.platform`` for the platform in question.
+
+   The default values are ``os.name`` and ``sys.platform``.
+
+
+.. function:: set_compiler(location)
+
+   Add or change a compiler
+
+
+.. function:: show_compilers()
+
+   Print list of available compilers (used by the :option:`--help-compiler`
+   options to :command:`build`, :command:`build_ext`, :command:`build_clib`).
+

+
+:mod:`packaging.compiler.ccompiler` --- CCompiler base class
+============================================================
+
+.. module:: packaging.compiler.ccompiler
+   :synopsis: Abstract CCompiler class.
+
+
+This module provides the abstract base class for the :class:`CCompiler`
+classes.  A :class:`CCompiler` instance can be used for all the compile and
+link steps needed to build a single project. Methods are provided to set
+options for the compiler --- macro definitions, include directories, link path,
+libraries and the like.
+
+.. class:: CCompiler([verbose=0, dry_run=0, force=0])
+
+   The abstract base class :class:`CCompiler` defines the interface that must be
+   implemented by real compiler classes.  The class also has some utility
+   methods used by several compiler classes.
+
+   The basic idea behind a compiler abstraction class is that each instance can
+   be used for all the compile/link steps in building a single project.  Thus,
+   attributes common to all of those compile and link steps --- include
+   directories, macros to define, libraries to link against, etc. --- are
+   attributes of the compiler instance.  To allow for variability in how
+   individual files are treated, most of those attributes may be varied on a
+   per-compilation or per-link basis.
+
+   The constructor for each subclass creates an instance of the Compiler object.
+   Flags are *verbose* (show verbose output), *dry_run* (don't actually execute
+   the steps) and *force* (rebuild everything, regardless of dependencies).  All
+   of these flags default to ``0`` (off). Note that you probably don't want to
+   instantiate :class:`CCompiler` or one of its subclasses directly - use the
+   :func:`packaging.CCompiler.new_compiler` factory function instead.
+
+   The following methods allow you to manually alter compiler options for the
+   instance of the Compiler class.
+
+
+   .. method:: CCompiler.add_include_dir(dir)
+
+      Add *dir* to the list of directories that will be searched for header
+      files.  The compiler is instructed to search directories in the order in
+      which they are supplied by successive calls to :meth:`add_include_dir`.
+
+
+   .. method:: CCompiler.set_include_dirs(dirs)
+
+      Set the list of directories that will be searched to *dirs* (a list of
+      strings). Overrides any preceding calls to :meth:`add_include_dir`;
+      subsequent calls to :meth:`add_include_dir` add to the list passed to
+      :meth:`set_include_dirs`. This does not affect any list of standard
+      include directories that the compiler may search by default.
+
+
+   .. method:: CCompiler.add_library(libname)
+
+      Add *libname* to the list of libraries that will be included in all links
+      driven by this compiler object.  Note that *libname* should *not* be the
+      name of a file containing a library, but the name of the library itself:
+      the actual filename will be inferred by the linker, the compiler, or the
+      compiler class (depending on the platform).
+
+      The linker will be instructed to link against libraries in the order they
+      were supplied to :meth:`add_library` and/or :meth:`set_libraries`.  It is
+      perfectly valid to duplicate library names; the linker will be instructed
+      to link against libraries as many times as they are mentioned.
+
+
+   .. method:: CCompiler.set_libraries(libnames)
+
+      Set the list of libraries to be included in all links driven by this
+      compiler object to *libnames* (a list of strings).  This does not affect
+      any standard system libraries that the linker may include by default.
+
+
+   .. method:: CCompiler.add_library_dir(dir)
+
+      Add *dir* to the list of directories that will be searched for libraries
+      specified to :meth:`add_library` and :meth:`set_libraries`.  The linker
+      will be instructed to search for libraries in the order they are supplied
+      to :meth:`add_library_dir` and/or :meth:`set_library_dirs`.
+
+
+   .. method:: CCompiler.set_library_dirs(dirs)
+
+      Set the list of library search directories to *dirs* (a list of strings).
+      This does not affect any standard library search path that the linker may
+      search by default.
+
+
+   .. method:: CCompiler.add_runtime_library_dir(dir)
+
+      Add *dir* to the list of directories that will be searched for shared
+      libraries at runtime.
+
+
+   .. method:: CCompiler.set_runtime_library_dirs(dirs)
+
+      Set the list of directories to search for shared libraries at runtime to
+      *dirs* (a list of strings).  This does not affect any standard search path
+      that the runtime linker may search by default.
+
+
+   .. method:: CCompiler.define_macro(name[, value=None])
+
+      Define a preprocessor macro for all compilations driven by this compiler
+      object. The optional parameter *value* should be a string; if it is not
+      supplied, then the macro will be defined without an explicit value and the
+      exact outcome depends on the compiler used (XXX true? does ANSI say
+      anything about this?)
+
+
+   .. method:: CCompiler.undefine_macro(name)
+
+      Undefine a preprocessor macro for all compilations driven by this compiler
+      object.  If the same macro is defined by :meth:`define_macro` and
+      undefined by :meth:`undefine_macro` the last call takes precedence
+      (including multiple redefinitions or undefinitions).  If the macro is
+      redefined/undefined on a per-compilation basis (i.e. in the call to
+      :meth:`compile`), then that takes precedence.
+
+
+   .. method:: CCompiler.add_link_object(object)
+
+      Add *object* to the list of object files (or analogues, such as explicitly
+      named library files or the output of "resource compilers") to be included
+      in every link driven by this compiler object.
+
+
+   .. method:: CCompiler.set_link_objects(objects)
+
+      Set the list of object files (or analogues) to be included in every link
+      to *objects*.  This does not affect any standard object files that the
+      linker may include by default (such as system libraries).
+
+   The following methods implement methods for autodetection of compiler
+   options, providing some functionality similar to GNU :program:`autoconf`.
+
+
+   .. method:: CCompiler.detect_language(sources)
+
+      Detect the language of a given file, or list of files. Uses the instance
+      attributes :attr:`language_map` (a dictionary), and :attr:`language_order`
+      (a list) to do the job.
+
+
+   .. method:: CCompiler.find_library_file(dirs, lib[, debug=0])
+
+      Search the specified list of directories for a static or shared library file
+      *lib* and return the full path to that file.  If *debug* is true, look for a
+      debugging version (if that makes sense on the current platform).  Return
+      ``None`` if *lib* wasn't found in any of the specified directories.
+
+
+   .. method:: CCompiler.has_function(funcname [, includes=None, include_dirs=None, libraries=None, library_dirs=None])
+
+      Return a boolean indicating whether *funcname* is supported on the current
+      platform.  The optional arguments can be used to augment the compilation
+      environment by providing additional include files and paths and libraries and
+      paths.
+
+
+   .. method:: CCompiler.library_dir_option(dir)
+
+      Return the compiler option to add *dir* to the list of directories searched for
+      libraries.
+
+
+   .. method:: CCompiler.library_option(lib)
+
+      Return the compiler option to add *dir* to the list of libraries linked into the
+      shared library or executable.
+
+
+   .. method:: CCompiler.runtime_library_dir_option(dir)
+
+      Return the compiler option to add *dir* to the list of directories searched for
+      runtime libraries.
+
+
+   .. method:: CCompiler.set_executables(**args)
+
+      Define the executables (and options for them) that will be run to perform the
+      various stages of compilation.  The exact set of executables that may be
+      specified here depends on the compiler class (via the 'executables' class
+      attribute), but most will have:
+
+      +--------------+------------------------------------------+
+      | attribute    | description                              |
+      +==============+==========================================+
+      | *compiler*   | the C/C++ compiler                       |
+      +--------------+------------------------------------------+
+      | *linker_so*  | linker used to create shared objects and |
+      |              | libraries                                |
+      +--------------+------------------------------------------+
+      | *linker_exe* | linker used to create binary executables |
+      +--------------+------------------------------------------+
+      | *archiver*   | static library creator                   |
+      +--------------+------------------------------------------+
+
+      On platforms with a command line (Unix, DOS/Windows), each of these is a string
+      that will be split into executable name and (optional) list of arguments.
+      (Splitting the string is done similarly to how Unix shells operate: words are
+      delimited by spaces, but quotes and backslashes can override this.  See
+      :func:`packaging.util.split_quoted`.)
+
+   The following methods invoke stages in the build process.
+
+
+   .. method:: CCompiler.compile(sources[, output_dir=None, macros=None, include_dirs=None, debug=0, extra_preargs=None, extra_postargs=None, depends=None])
+
+      Compile one or more source files. Generates object files (e.g. transforms a
+      :file:`.c` file to a :file:`.o` file.)
+
+      *sources* must be a list of filenames, most likely C/C++ files, but in reality
+      anything that can be handled by a particular compiler and compiler class (e.g.
+      an ``'msvc'`` compiler` can handle resource files in *sources*).  Return a list of
+      object filenames, one per source filename in *sources*.  Depending on the
+      implementation, not all source files will necessarily be compiled, but all
+      corresponding object filenames will be returned.
+
+      If *output_dir* is given, object files will be put under it, while retaining
+      their original path component.  That is, :file:`foo/bar.c` normally compiles to
+      :file:`foo/bar.o` (for a Unix implementation); if *output_dir* is *build*, then
+      it would compile to :file:`build/foo/bar.o`.
+
+      *macros*, if given, must be a list of macro definitions.  A macro definition is
+      either a ``(name, value)`` 2-tuple or a ``(name,)`` 1-tuple. The former defines
+      a macro; if the value is ``None``, the macro is defined without an explicit
+      value.  The 1-tuple case undefines a macro.  Later
+      definitions/redefinitions/undefinitions take precedence.
+
+      *include_dirs*, if given, must be a list of strings, the directories to add to
+      the default include file search path for this compilation only.
+
+      *debug* is a boolean; if true, the compiler will be instructed to output debug
+      symbols in (or alongside) the object file(s).
+
+      *extra_preargs* and *extra_postargs* are implementation-dependent. On platforms
+      that have the notion of a command line (e.g. Unix, DOS/Windows), they are most
+      likely lists of strings: extra command-line arguments to prepend/append to the
+      compiler command line.  On other platforms, consult the implementation class
+      documentation.  In any event, they are intended as an escape hatch for those
+      occasions when the abstract compiler framework doesn't cut the mustard.
+
+      *depends*, if given, is a list of filenames that all targets depend on.  If a
+      source file is older than any file in depends, then the source file will be
+      recompiled.  This supports dependency tracking, but only at a coarse
+      granularity.
+
+      Raises :exc:`CompileError` on failure.
+
+
+   .. method:: CCompiler.create_static_lib(objects, output_libname[, output_dir=None, debug=0, target_lang=None])
+
+      Link a bunch of stuff together to create a static library file. The "bunch of
+      stuff" consists of the list of object files supplied as *objects*, the extra
+      object files supplied to :meth:`add_link_object` and/or
+      :meth:`set_link_objects`, the libraries supplied to :meth:`add_library` and/or
+      :meth:`set_libraries`, and the libraries supplied as *libraries* (if any).
+
+      *output_libname* should be a library name, not a filename; the filename will be
+      inferred from the library name.  *output_dir* is the directory where the library
+      file will be put. XXX defaults to what?
+
+      *debug* is a boolean; if true, debugging information will be included in the
+      library (note that on most platforms, it is the compile step where this matters:
+      the *debug* flag is included here just for consistency).
+
+      *target_lang* is the target language for which the given objects are being
+      compiled. This allows specific linkage time treatment of certain languages.
+
+      Raises :exc:`LibError` on failure.
+
+
+   .. method:: CCompiler.link(target_desc, objects, output_filename[, output_dir=None, libraries=None, library_dirs=None, runtime_library_dirs=None, export_symbols=None, debug=0, extra_preargs=None, extra_postargs=None, build_temp=None, target_lang=None])
+
+      Link a bunch of stuff together to create an executable or shared library file.
+
+      The "bunch of stuff" consists of the list of object files supplied as *objects*.
+      *output_filename* should be a filename.  If *output_dir* is supplied,
+      *output_filename* is relative to it (i.e. *output_filename* can provide
+      directory components if needed).
+
+      *libraries* is a list of libraries to link against.  These are library names,
+      not filenames, since they're translated into filenames in a platform-specific
+      way (e.g. *foo* becomes :file:`libfoo.a` on Unix and :file:`foo.lib` on
+      DOS/Windows).  However, they can include a directory component, which means the
+      linker will look in that specific directory rather than searching all the normal
+      locations.
+
+      *library_dirs*, if supplied, should be a list of directories to search for
+      libraries that were specified as bare library names (i.e. no directory
+      component).  These are on top of the system default and those supplied to
+      :meth:`add_library_dir` and/or :meth:`set_library_dirs`.  *runtime_library_dirs*
+      is a list of directories that will be embedded into the shared library and used
+      to search for other shared libraries that \*it\* depends on at run-time.  (This
+      may only be relevant on Unix.)
+
+      *export_symbols* is a list of symbols that the shared library will export.
+      (This appears to be relevant only on Windows.)
+
+      *debug* is as for :meth:`compile` and :meth:`create_static_lib`, with the
+      slight distinction that it actually matters on most platforms (as opposed to
+      :meth:`create_static_lib`, which includes a *debug* flag mostly for form's
+      sake).
+
+      *extra_preargs* and *extra_postargs* are as for :meth:`compile` (except of
+      course that they supply command-line arguments for the particular linker being
+      used).
+
+      *target_lang* is the target language for which the given objects are being
+      compiled. This allows specific linkage time treatment of certain languages.
+
+      Raises :exc:`LinkError` on failure.
+
+
+   .. method:: CCompiler.link_executable(objects, output_progname[, output_dir=None, libraries=None, library_dirs=None, runtime_library_dirs=None, debug=0, extra_preargs=None, extra_postargs=None, target_lang=None])
+
+      Link an executable.  *output_progname* is the name of the file executable, while
+      *objects* are a list of object filenames to link in. Other arguments are as for
+      the :meth:`link` method.
+
+
+   .. method:: CCompiler.link_shared_lib(objects, output_libname[, output_dir=None, libraries=None, library_dirs=None, runtime_library_dirs=None, export_symbols=None, debug=0, extra_preargs=None, extra_postargs=None, build_temp=None, target_lang=None])
+
+      Link a shared library. *output_libname* is the name of the output library,
+      while *objects* is a list of object filenames to link in. Other arguments are
+      as for the :meth:`link` method.
+
+
+   .. method:: CCompiler.link_shared_object(objects, output_filename[, output_dir=None, libraries=None, library_dirs=None, runtime_library_dirs=None, export_symbols=None, debug=0, extra_preargs=None, extra_postargs=None, build_temp=None, target_lang=None])
+
+      Link a shared object. *output_filename* is the name of the shared object that
+      will be created, while *objects* is a list of object filenames to link in.
+      Other arguments are as for the :meth:`link` method.
+
+
+   .. method:: CCompiler.preprocess(source[, output_file=None, macros=None, include_dirs=None, extra_preargs=None, extra_postargs=None])
+
+      Preprocess a single C/C++ source file, named in *source*. Output will be written
+      to file named *output_file*, or *stdout* if *output_file* not supplied.
+      *macros* is a list of macro definitions as for :meth:`compile`, which will
+      augment the macros set with :meth:`define_macro` and :meth:`undefine_macro`.
+      *include_dirs* is a list of directory names that will be added to the default
+      list, in the same way as :meth:`add_include_dir`.
+
+      Raises :exc:`PreprocessError` on failure.
+
+   The following utility methods are defined by the :class:`CCompiler` class, for
+   use by the various concrete subclasses.
+
+
+   .. method:: CCompiler.executable_filename(basename[, strip_dir=0, output_dir=''])
+
+      Returns the filename of the executable for the given *basename*.  Typically for
+      non-Windows platforms this is the same as the basename, while Windows will get
+      a :file:`.exe` added.
+
+
+   .. method:: CCompiler.library_filename(libname[, lib_type='static', strip_dir=0, output_dir=''])
+
+      Returns the filename for the given library name on the current platform. On Unix
+      a library with *lib_type* of ``'static'`` will typically be of the form
+      :file:`liblibname.a`, while a *lib_type* of ``'dynamic'`` will be of the form
+      :file:`liblibname.so`.
+
+
+   .. method:: CCompiler.object_filenames(source_filenames[, strip_dir=0, output_dir=''])
+
+      Returns the name of the object files for the given source files.
+      *source_filenames* should be a list of filenames.
+
+
+   .. method:: CCompiler.shared_object_filename(basename[, strip_dir=0, output_dir=''])
+
+      Returns the name of a shared object file for the given file name *basename*.
+
+
+   .. method:: CCompiler.execute(func, args[, msg=None, level=1])
+
+      Invokes :func:`packaging.util.execute` This method invokes a Python function
+      *func* with the given arguments *args*, after logging and taking into account
+      the *dry_run* flag. XXX see also.
+
+
+   .. method:: CCompiler.spawn(cmd)
+
+      Invokes :func:`packaging.util.spawn`. This invokes an external process to run
+      the given command. XXX see also.
+
+
+   .. method:: CCompiler.mkpath(name[, mode=511])
+
+      Invokes :func:`packaging.dir_util.mkpath`. This creates a directory and any
+      missing ancestor directories. XXX see also.
+
+
+   .. method:: CCompiler.move_file(src, dst)
+
+      Invokes :meth:`packaging.file_util.move_file`. Renames *src* to *dst*.  XXX see
+      also.

+:mod:`packaging.database` --- Database of installed distributions
+=================================================================
+
+.. module:: packaging.database
+   :synopsis: Functions to query and manipulate installed distributions.
+
+
+This module provides an implementation of :PEP:`376`.  It was originally
+intended to land in :mod:`pkgutil`, but with the inclusion of Packaging in the
+standard library, it was thought best to include it in a submodule of
+:mod:`packaging`, leaving :mod:`pkgutil` to deal with imports.
+
+Installed Python distributions are represented by instances of
+:class:`Distribution`, or :class:`EggInfoDistribution` for legacy egg formats.
+Most functions also provide an extra argument ``use_egg_info`` to take legacy
+distributions into account.
+
+
+Classes representing installed distributions
+--------------------------------------------
+
+.. class:: Distribution(path)
+
+   Class representing an installed distribution.  It is different from
+   :class:`packaging.dist.Distribution` which holds the list of files, the
+   metadata and options during the run of a Packaging command.
+
+   Instantiate with the *path* to a ``.dist-info`` directory.  Instances can be
+   compared and sorted.  Other available methods are:
+
+   .. XXX describe how comparison works
+
+   .. method:: get_distinfo_file(path, binary=False)
+
+      Return a read-only file object for a file located at
+      :file:`{project-version}.dist-info/path}`.  *path* should be a
+      ``'/'``-separated path relative to the ``.dist-info`` directory or an
+      absolute path; if it is an absolute path and doesn't start with the path
+      to the :file:`.dist-info` directory, a :class:`PackagingError` is raised.
+
+      If *binary* is ``True``, the file is opened in binary mode.
+
+   .. method:: get_resource_path(relative_path)
+
+      .. TODO
+
+   .. method:: list_distinfo_files(local=False)
+
+      Return an iterator over all files located in the :file:`.dist-info`
+      directory.  If *local* is ``True``, each returned path is transformed into
+      a local absolute path, otherwise the raw value found in the :file:`RECORD`
+      file is returned.
+
+   .. method::  list_installed_files(local=False)
+
+      Iterate over the files installed with the distribution and registered in
+      the :file:`RECORD` file and yield a tuple ``(path, md5, size)`` for each
+      line.  If *local* is ``True``, the returned path is transformed into a
+      local absolute path, otherwise the raw value is returned.
+
+      A local absolute path is an absolute path in which occurrences of ``'/'``
+      have been replaced by :data:`os.sep`.
+
+   .. method:: uses(path)
+
+      Check whether *path* was installed by this distribution (i.e. if the path
+      is present in the :file:`RECORD` file).  *path* can be a local absolute
+      path or a relative ``'/'``-separated path.  Returns a boolean.
+
+   Available attributes:
+
+   .. attribute:: metadata
+
+      Instance of :class:`packaging.metadata.Metadata` filled with the contents
+      of the :file:`{project-version}.dist-info/METADATA` file.
+
+   .. attribute:: name
+
+      Shortcut for ``metadata['Name']``.
+
+   .. attribute:: version
+
+      Shortcut for ``metadata['Version']``.
+
+   .. attribute:: requested
+
+      Boolean indicating whether this distribution was requested by the user of
+      automatically installed as a dependency.
+
+
+.. class:: EggInfoDistribution(path)
+
+   Class representing a legacy distribution.  It is compatible with distutils'
+   and setuptools' :file:`.egg-info` and :file:`.egg` files and directories.
+
+   .. FIXME should be named EggDistribution
+
+   Instantiate with the *path* to an egg file or directory.  Instances can be
+   compared and sorted.  Other available methods are:
+
+   .. method:: list_installed_files(local=False)
+
+   .. method:: uses(path)
+
+   Available attributes:
+
+   .. attribute:: metadata
+
+      Instance of :class:`packaging.metadata.Metadata` filled with the contents
+      of the :file:`{project-version}.egg-info/PKG-INFO` or
+      :file:`{project-version}.egg` file.
+
+   .. attribute:: name
+
+      Shortcut for ``metadata['Name']``.
+
+   .. attribute:: version
+
+      Shortcut for ``metadata['Version']``.
+
+
+Functions to work with the database
+-----------------------------------
+
+.. function:: get_distribution(name, use_egg_info=False, paths=None)
+
+   Return an instance of :class:`Distribution` or :class:`EggInfoDistribution`
+   for the first installed distribution matching *name*.  Egg distributions are
+   considered only if *use_egg_info* is true; if both a dist-info and an egg
+   file are found, the dist-info prevails.  The directories to be searched are
+   given in *paths*, which defaults to :data:`sys.path`.  Return ``None`` if no
+   matching distribution is found.
+
+   .. FIXME param should be named use_egg
+
+
+.. function:: get_distributions(use_egg_info=False, paths=None)
+
+   Return an iterator of :class:`Distribution` instances for all installed
+   distributions found in *paths* (defaults to :data:`sys.path`).  If
+   *use_egg_info* is true, also return instances of :class:`EggInfoDistribution`
+   for legacy distributions found.
+
+
+.. function:: get_file_users(path)
+
+   Return an iterator over all distributions using *path*, a local absolute path
+   or a relative ``'/'``-separated path.
+
+   .. XXX does this work with prefixes or full file path only?
+
+
+.. function:: obsoletes_distribution(name, version=None, use_egg_info=False)
+
+   Return an iterator over all distributions that declare they obsolete *name*.
+   *version* is an optional argument to match only specific releases (see
+   :mod:`packaging.version`).  If *use_egg_info* is true, legacy egg
+   distributions will be considered as well.
+
+
+.. function:: provides_distribution(name, version=None, use_egg_info=False)
+
+   Return an iterator over all distributions that declare they provide *name*.
+   *version* is an optional argument to match only specific releases (see
+   :mod:`packaging.version`).  If *use_egg_info* is true, legacy egg
+   distributions will be considered as well.
+
+
+Utility functions
+-----------------
+
+.. function:: distinfo_dirname(name, version)
+
+   Escape *name* and *version* into a filename-safe form and return the
+   directory name built from them, for example
+   :file:`{safename}-{safeversion}.dist-info.`  In *name*, runs of
+   non-alphanumeric characters are replaced with one ``'_'``; in *version*,
+   spaces become dots, and runs of other non-alphanumeric characters (except
+   dots) a replaced by one ``'-'``.
+
+   .. XXX wth spaces in version numbers?
+
+For performance purposes, the list of distributions is being internally
+cached.   Caching is enabled by default, but you can control it with these
+functions:
+
+.. function:: clear_cache()
+
+   Clear the cache.
+
+.. function:: disable_cache()
+
+   Disable the cache, without clearing it.
+
+.. function:: enable_cache()
+
+   Enable the internal cache, without clearing it.
+
+
+Examples
+--------
+
+Print all information about a distribution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Given a path to a ``.dist-info`` distribution, we shall print out all
+information that can be obtained using functions provided in this module::
+
+   import sys
+   import packaging.database
+
+   path = input()
+   # first create the Distribution instance
+   try:
+       dist = packaging.database.Distribution(path)
+   except IOError:
+       sys.exit('No such distribution')
+
+   print('Information about %r' % dist.name)
+   print()
+
+   print('Files')
+   print('=====')
+   for path, md5, size in dist.list_installed_files():
+       print('* Path: %s' % path)
+       print('  Hash %s, Size: %s bytes' % (md5, size))
+   print()
+
+   print('Metadata')
+   print('========')
+   for key, value in dist.metadata.items():
+       print('%20s: %s' % (key, value))
+   print()
+
+   print('Extra')
+   print('=====')
+   if dist.requested:
+       print('* It was installed by user request')
+   else:
+       print('* It was installed as a dependency')
+
+If we save the script above as ``print_info.py``, we can use it to extract
+information from a :file:`.dist-info` directory.  By typing in the console:
+
+.. code-block:: sh
+
+   $ echo /tmp/choxie/choxie-2.0.0.9.dist-info | python3 print_info.py
+
+we get the following output:

+Find out obsoleted distributions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Now, we take tackle a different problem, we are interested in finding out
+which distributions have been obsoleted. This can be easily done as follows::
+
+  import packaging.database
+
+  # iterate over all distributions in the system
+  for dist in packaging.database.get_distributions():
+      name, version = dist.name, dist.version
+      # find out which distributions obsolete this name/version combination
+      replacements = packaging.database.obsoletes_distribution(name, version)
+      if replacements:
+          print('%r %s is obsoleted by' % (name, version),
+                ', '.join(repr(r.name) for r in replacements))
+
+This is how the output might look like:
+
+.. code-block:: none
+
+  'strawberry' 0.6 is obsoleted by 'choxie'
+  'grammar' 1.0a4 is obsoleted by 'towel-stuff'

+:mod:`packaging.depgraph` --- Dependency graph builder
+======================================================
+
+.. module:: packaging.depgraph
+   :synopsis: Graph builder for dependencies between releases.
+
+
+This module provides the means to analyse the dependencies between various
+distributions and to create a graph representing these dependency relationships.
+In this document, "distribution" refers to an instance of
+:class:`packaging.database.Distribution` or
+:class:`packaging.database.EggInfoDistribution`.
+
+.. XXX terminology problem with dist vs. release: dists are installed, but deps
+   use releases
+
+.. XXX explain how to use it with dists not installed: Distribution can only be
+   instantiated with a path, but this module is useful for remote dist too
+
+.. XXX functions should accept and return iterators, not lists
+
+
+The :class:`DependencyGraph` class
+----------------------------------
+
+.. class:: DependencyGraph
+
+   Represent a dependency graph between releases.  The nodes are distribution
+   instances; the edge model dependencies.  An edge from ``a`` to ``b`` means
+   that ``a`` depends on ``b``.
+
+   .. method:: add_distribution(distribution)
+
+      Add *distribution* to the graph.
+
+   .. method:: add_edge(x, y, label=None)
+
+      Add an edge from distribution *x* to distribution *y* with the given
+      *label* (string).
+
+   .. method:: add_missing(distribution, requirement)
+
+      Add a missing *requirement* (string) for the given *distribution*.
+
+   .. method:: repr_node(dist, level=1)
+
+      Print a subgraph starting from *dist*.  *level* gives the depth of the
+      subgraph.
+
+   Direct access to the graph nodes and edges is provided through these
+   attributes:
+
+   .. attribute:: adjacency_list
+
+      Dictionary mapping distributions to a list of ``(other, label)`` tuples
+      where  ``other`` is a distribution and the edge is labeled with ``label``
+      (i.e. the version specifier, if such was provided).
+
+   .. attribute:: reverse_list
+
+      Dictionary mapping distributions to a list of predecessors.  This allows
+      efficient traversal.
+
+   .. attribute:: missing
+
+      Dictionary mapping distributions to a list of requirements that were not
+      provided by any distribution.
+
+
+Auxiliary functions
+-------------------
+
+.. function:: dependent_dists(dists, dist)
+
+   Recursively generate a list of distributions from *dists* that are dependent
+   on *dist*.
+
+   .. XXX what does member mean here: "dist is a member of *dists* for which we
+      are interested"
+
+.. function:: generate_graph(dists)
+
+   Generate a :class:`DependencyGraph` from the given list of distributions.
+
+   .. XXX make this alternate constructor a DepGraph classmethod or rename;

+
+.. function:: graph_to_dot(graph, f, skip_disconnected=True)
+
+   Write a DOT output for the graph to the file-like object *f*.
+
+   If *skip_disconnected* is true, all distributions that are not dependent on
+   any other distribution are skipped.
+
+   .. XXX why is this not a DepGraph method?
+
+
+Example Usage
+-------------
+
+Depict all dependenciess in the system
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+First, we shall generate a graph of all the distributions on the system
+and then create an image out of it using the tools provided by
+`Graphviz <http://www.graphviz.org/>`_::
+
+   from packaging.database import get_distributions
+   from packaging.depgraph import generate_graph
+
+   dists = list(get_distributions())
+   graph = generate_graph(dists)
+
+It would be interesting to print out the missing requirements.  This can be done
+as follows::
+
+   for dist, reqs in graph.missing.items():
+       if reqs:
+           reqs = ' ,'.join(repr(req) for req in reqs)
+           print('Missing dependencies for %r: %s' % (dist.name, reqs))
+
+Example output is:
+
+.. code-block:: none
+
+   Missing dependencies for 'TurboCheetah': 'Cheetah'
+   Missing dependencies for 'TurboGears': 'ConfigObj', 'DecoratorTools', 'RuleDispatch'
+   Missing dependencies for 'jockey': 'PyKDE4.kdecore', 'PyKDE4.kdeui', 'PyQt4.QtCore', 'PyQt4.QtGui'
+   Missing dependencies for 'TurboKid': 'kid'
+   Missing dependencies for 'TurboJson: 'DecoratorTools', 'RuleDispatch'
+
+Now, we proceed with generating a graphical representation of the graph. First
+we write it to a file, and then we generate a PNG image using the
+:program:`dot` command-line tool::
+
+   from packaging.depgraph import graph_to_dot
+   with open('output.dot', 'w') as f:
+      # only show the interesting distributions, skipping the disconnected ones
+      graph_to_dot(graph, f, skip_disconnected=True)
+
+We can create the final picture using:
+
+.. code-block:: sh
+
+   $ dot -Tpng output.dot > output.png
+
+An example result is:
+
+.. figure:: depgraph-output.png
+   :alt: Example PNG output from packaging.depgraph and dot
+
+If you want to include egg distributions as well, then the code requires only
+one change, namely the line::
+
+   dists = list(packaging.database.get_distributions())
+
+has to be replaced with::
+
+   dists = list(packaging.database.get_distributions(use_egg_info=True))
+
+On many platforms, a richer graph is obtained because at the moment most
+distributions are provided in the egg rather than the new standard
+``.dist-info`` format.
+
+.. XXX missing image
+
+   An example of a more involved graph for illustrative reasons can be seen
+   here:
+
+   .. image:: depgraph_big.png
+
+
+List all dependent distributions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We will list all distributions that are dependent on some given distibution.
+This time, egg distributions will be considered as well::
+
+   import sys
+   from packaging.database import get_distribution, get_distributions
+   from packaging.depgraph import dependent_dists
+
+   dists = list(get_distributions(use_egg_info=True))
+   dist = get_distribution('bacon', use_egg_info=True)
+   if dist is None:
+       sys.exit('No such distribution in the system')
+
+   deps = dependent_dists(dists, dist)
+   deps = ', '.join(repr(x.name) for x in deps)
+   print('Distributions depending on %r: %s' % (dist.name, deps))
+
+And this is example output:
+
+.. with the dependency relationships as in the previous section
+   (depgraph_big)
+
+.. code-block:: none
+
+   Distributions depending on 'bacon': 'towel-stuff', 'choxie', 'grammar'

+:mod:`packaging.dist` --- The Distribution class
+================================================
+
+.. module:: packaging.dist
+   :synopsis: Core Distribution class.
+
+
+This module provides the :class:`Distribution` class, which represents the
+module distribution being built/packaged/distributed/installed.
+
+.. class:: Distribution(arguments)
+
+   A :class:`Distribution` describes how to build, package, distribute and
+   install a Python project.
+
+   The arguments accepted by the constructor are laid out in the following
+   table.  Some of them will end up in a metadata object, the rest will become
+   data attributes of the :class:`Distribution` instance.
+
+   .. TODO improve constructor to take a Metadata object + named params?
+      (i.e. Distribution(metadata, cmdclass, py_modules, etc)
+   .. TODO also remove obsolete(?) script_name, etc. parameters?  see what
+      py2exe and other tools need

+:mod:`packaging.fancy_getopt` --- Wrapper around the getopt module
+==================================================================
+
+.. module:: packaging.fancy_getopt
+   :synopsis: Additional getopt functionality.
+
+
+.. warning::
+   This module is deprecated and will be replaced with :mod:`optparse`.
+
+This module provides a wrapper around the standard :mod:`getopt` module that
+provides the following additional features:
+
+* short and long options are tied together
+
+* options have help strings, so :func:`fancy_getopt` could potentially create a
+  complete usage summary
+
+* options set attributes of a passed-in object
+
+* boolean options can have "negative aliases" --- e.g. if :option:`--quiet` is
+  the "negative alias" of :option:`--verbose`, then :option:`--quiet` on the
+  command line sets *verbose* to false.
+
+.. function:: fancy_getopt(options, negative_opt, object, args)
+
+   Wrapper function. *options* is a list of ``(long_option, short_option,
+   help_string)`` 3-tuples as described in the constructor for
+   :class:`FancyGetopt`. *negative_opt* should be a dictionary mapping option names
+   to option names, both the key and value should be in the *options* list.
+   *object* is an object which will be used to store values (see the :meth:`getopt`
+   method of the :class:`FancyGetopt` class). *args* is the argument list. Will use
+   ``sys.argv[1:]`` if you pass ``None`` as *args*.
+
+
+.. class:: FancyGetopt([option_table=None])
+
+   The option_table is a list of 3-tuples: ``(long_option, short_option,
+   help_string)``
+
+   If an option takes an argument, its *long_option* should have ``'='`` appended;
+   *short_option* should just be a single character, no ``':'`` in any case.
+   *short_option* should be ``None`` if a *long_option* doesn't have a
+   corresponding *short_option*. All option tuples must have long options.
+
+The :class:`FancyGetopt` class provides the following methods:
+
+
+.. method:: FancyGetopt.getopt([args=None, object=None])
+
+   Parse command-line options in args. Store as attributes on *object*.
+
+   If *args* is ``None`` or not supplied, uses ``sys.argv[1:]``.  If *object* is
+   ``None`` or not supplied, creates a new :class:`OptionDummy` instance, stores
+   option values there, and returns a tuple ``(args, object)``.  If *object* is
+   supplied, it is modified in place and :func:`getopt` just returns *args*; in
+   both cases, the returned *args* is a modified copy of the passed-in *args* list,
+   which is left untouched.
+
+   .. TODO and args returned are?
+
+
+.. method:: FancyGetopt.get_option_order()
+
+   Returns the list of ``(option, value)`` tuples processed by the previous run of
+   :meth:`getopt`  Raises :exc:`RuntimeError` if :meth:`getopt` hasn't been called
+   yet.
+
+
+.. method:: FancyGetopt.generate_help([header=None])
+
+   Generate help text (a list of strings, one per suggested line of output) from
+   the option table for this :class:`FancyGetopt` object.
+
+   If supplied, prints the supplied *header* at the top of the help.

+:mod:`packaging.install` --- Installation tools
+===============================================
+
+.. module:: packaging.install
+   :synopsis: Download and installation building blocks
+
+
+Packaging provides a set of tools to deal with downloads and installation of
+distributions.  Their role is to download the distribution from indexes, resolve
+the dependencies, and provide a safe way to install distributions.  An operation
+that fails will cleanly roll back, not leave half-installed distributions on the
+system.  Here's the basic process followed:
+
+#. Move all distributions that will be removed to a temporary location.
+
+#. Install all the distributions that will be installed in a temporary location.
+
+#. If the installation fails, move the saved distributions back to their
+   location and delete the installed distributions.
+
+#. Otherwise, move the installed distributions to the right location and delete
+   the temporary locations.
+
+This is a higher-level module built on :mod:`packaging.database` and
+:mod:`packaging.pypi`.
+
+
+Public functions
+----------------
+
+.. function:: get_infos(requirements, index=None, installed=None, \
+                        prefer_final=True)
+
+   Return information about what's going to be installed and upgraded.
+   *requirements* is a string string containing the requirements for this
+   project, for example ``'FooBar 1.1'`` or ``'BarBaz (<1.2)'``.
+

+
+
+.. function:: install(project)
+
+
+.. function:: install_dists(dists, path, paths=None)
+
+   Safely install all distributions provided in *dists* into *path*.  *paths* is
+   a list of paths where already-installed distributions will be looked for to
+   find satisfied dependencies and conflicts (default: :data:`sys.path`).
+   Returns a list of installed dists.
+
+   .. FIXME dists are instances of what?
+
+
+.. function:: install_from_infos(install_path=None, install=[], remove=[], \
+                                 conflicts=[], paths=None)
+
+   Safely install and remove given distributions.  This function is designed to
+   work with the return value of :func:`get_infos`: *install*, *remove* and
+   *conflicts* should be list of distributions returned by :func:`get_infos`.
+   If *install* is not empty, *install_path* must be given to specify the path
+   where the distributions should be installed.  *paths* is a list of paths
+   where already-installed distributions will be looked for (default:
+   :data:`sys.path`).
+
+   This function is a very basic installer; if *conflicts* is not empty, the
+   system will be in a conflicting state after the function completes.  It is a
+   building block for more sophisticated installers with conflict resolution
+   systems.
+
+   .. TODO document typical value for install_path

+:mod:`packaging.metadata` --- Metadata handling
+===============================================
+
+.. module:: packaging.metadata
+   :synopsis: Class holding the metadata of a release.
+
+
+.. TODO use sphinx-autogen to generate basic doc from the docstrings
+
+.. class:: Metadata
+
+   This class can read and write metadata files complying with any of the
+   defined versions: 1.0 (:PEP:`241`), 1.1 (:PEP:`314`) and 1.2 (:PEP:`345`).  It
+   implements methods to parse Metadata files and write them, and a mapping
+   interface to its contents.
+
+   The :PEP:`345` implementation supports the micro-language for the environment
+   markers, and displays warnings when versions that are supposed to be
+   :PEP:`386`-compliant are violating the specification.
+
+
+Reading metadata
+----------------
+
+The :class:`Metadata` class can be instantiated
+with the path of the metadata file, and provides a dict-like interface to the
+values::
+
+   >>> from packaging.metadata import Metadata
+   >>> metadata = Metadata('PKG-INFO')
+   >>> metadata.keys()[:5]
+   ('Metadata-Version', 'Name', 'Version', 'Platform', 'Supported-Platform')
+   >>> metadata['Name']
+   'CLVault'
+   >>> metadata['Version']
+   '0.5'
+   >>> metadata['Requires-Dist']
+   ["pywin32; sys.platform == 'win32'", "Sphinx"]
+
+
+The fields that support environment markers can be automatically ignored if
+the object is instantiated using the ``platform_dependent`` option.
+:class:`Metadata` will interpret in this case
+the markers and will automatically remove the fields that are not compliant
+with the running environment. Here's an example under Mac OS X. The win32
+dependency we saw earlier is ignored::
+
+   >>> from packaging.metadata import Metadata
+   >>> metadata = Metadata('PKG-INFO', platform_dependent=True)
+   >>> metadata['Requires-Dist']
+   ['Sphinx']
+
+
+If you want to provide your own execution context, let's say to test the
+metadata under a particular environment that is not the current environment,
+you can provide your own values in the ``execution_context`` option, which
+is the dict that may contain one or more keys of the context the micro-language
+expects.
+
+Here's an example, simulating a win32 environment::
+
+   >>> from packaging.metadata import Metadata
+   >>> context = {'sys.platform': 'win32'}
+   >>> metadata = Metadata('PKG-INFO', platform_dependent=True,
+   ...                     execution_context=context)
+   ...
+   >>> metadata['Requires-Dist'] = ["pywin32; sys.platform == 'win32'",
+   ...                              "Sphinx"]
+   ...
+   >>> metadata['Requires-Dist']
+   ['pywin32', 'Sphinx']
+
+
+Writing metadata
+----------------
+
+Writing metadata can be done using the ``write`` method::
+
+   >>> metadata.write('/to/my/PKG-INFO')
+
+The class will pick the best version for the metadata, depending on the values
+provided. If all the values provided exist in all versions, the class will
+use :attr:`PKG_INFO_PREFERRED_VERSION`.  It is set by default to 1.0, the most
+widespread version.
+
+
+Conflict checking and best version
+----------------------------------
+
+Some fields in :PEP:`345` have to comply with the version number specification
+defined in :PEP:`386`.  When they don't comply, a warning is emitted::
+
+   >>> from packaging.metadata import Metadata
+   >>> metadata = Metadata()
+   >>> metadata['Requires-Dist'] = ['Funky (Groovie)']
+   "Funky (Groovie)" is not a valid predicate
+   >>> metadata['Requires-Dist'] = ['Funky (1.2)']
+
+See also :mod:`packaging.version`.
+
+
+.. TODO talk about check()
+
+
+:mod:`packaging.markers` --- Environment markers
+================================================
+
+.. module:: packaging.markers
+   :synopsis: Micro-language for environment markers
+
+
+This is an implementation of environment markers `as defined in PEP 345
+<http://www.python.org/dev/peps/pep-0345/#environment-markers>`_.  It is used
+for some metadata fields.
+
+.. function:: interpret(marker, execution_context=None)
+
+   Interpret a marker and return a boolean result depending on the environment.
+   Example:
+
+      >>> interpret("python_version > '1.0'")
+      True

+:mod:`packaging.pypi.dist` --- Classes representing query results
+=================================================================
+
+.. module:: packaging.pypi.dist
+   :synopsis: Classes representing the results of queries to indexes.
+
+
+Information coming from the indexes is held in instances of the classes defined
+in this module.
+
+Keep in mind that each project (eg. FooBar) can have several releases
+(eg. 1.1, 1.2, 1.3), and each of these releases can be provided in multiple
+distributions (eg. a source distribution, a binary one, etc).
+
+
+ReleaseInfo
+-----------
+
+Each release has a project name, version, metadata, and related distributions.
+
+This information is stored in :class:`ReleaseInfo`
+objects.
+
+.. class:: ReleaseInfo
+
+
+DistInfo
+---------
+
+:class:`DistInfo` is a simple class that contains
+information related to distributions; mainly the URLs where distributions
+can be found.
+
+.. class:: DistInfo
+
+
+ReleasesList
+------------
+
+The :mod:`~packaging.pypi.dist` module provides a class which works
+with lists of :class:`ReleaseInfo` classes;
+used to filter and order results.
+
+.. class:: ReleasesList
+
+
+Example usage
+-------------
+
+Build a list of releases and order them
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Assuming we have a list of releases::
+
+   >>> from packaging.pypi.dist import ReleasesList, ReleaseInfo
+   >>> fb10 = ReleaseInfo("FooBar", "1.0")
+   >>> fb11 = ReleaseInfo("FooBar", "1.1")
+   >>> fb11a = ReleaseInfo("FooBar", "1.1a1")
+   >>> ReleasesList("FooBar", [fb11, fb11a, fb10])
+   >>> releases.sort_releases()
+   >>> releases.get_versions()
+   ['1.1', '1.1a1', '1.0']
+   >>> releases.add_release("1.2a1")
+   >>> releases.get_versions()
+   ['1.1', '1.1a1', '1.0', '1.2a1']
+   >>> releases.sort_releases()
+   ['1.2a1', '1.1', '1.1a1', '1.0']
+   >>> releases.sort_releases(prefer_final=True)
+   >>> releases.get_versions()
+   ['1.1', '1.0', '1.2a1', '1.1a1']
+
+
+Add distribution related information to releases
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It's easy to add distribution information to releases::
+
+   >>> from packaging.pypi.dist import ReleasesList, ReleaseInfo
+   >>> r = ReleaseInfo("FooBar", "1.0")
+   >>> r.add_distribution("sdist", url="http://example.org/foobar-1.0.tar.gz")
+   >>> r.dists
+   {'sdist': FooBar 1.0 sdist}
+   >>> r['sdist'].url
+   {'url': 'http://example.org/foobar-1.0.tar.gz', 'hashname': None, 'hashval':
+   None, 'is_external': True}
+
+
+Getting attributes from the dist objects
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To abstract querying information returned from the indexes, attributes and
+release information can be retrieved directly from dist objects.
+
+For instance, if you have a release instance that does not contain the metadata
+attribute, it can be fetched by using the "fetch_metadata" method::
+
+   >>> r = Release("FooBar", "1.1")
+   >>> print r.metadata
+   None # metadata field is actually set to "None"
+   >>> r.fetch_metadata()
+   <Metadata for FooBar 1.1>
+
+.. XXX add proper roles to these constructs
+
+
+It's possible to retrieve a project's releases (`fetch_releases`),
+metadata (`fetch_metadata`) and distributions (`fetch_distributions`) using
+a similar work flow.
+
+.. XXX what is possible?
+
+Internally, this is possible because while retrieving information about
+projects, releases or distributions, a reference to the client used is
+stored which can be accessed using the objects `_index` attribute.

+:mod:`packaging.pypi` --- Interface to projects indexes
+=======================================================
+
+.. module:: packaging.pypi
+   :synopsis: Low-level and high-level APIs to query projects indexes.
+
+
+Packaging queries PyPI to get information about projects or download them.  The
+low-level facilities used internally are also part of the public API designed to
+be used by other tools.
+
+The :mod:`packaging.pypi` package provides those facilities, which can be
+used to access information about Python projects registered at indexes, the
+main one being PyPI, located ad http://pypi.python.org/.
+
+There is two ways to retrieve data from these indexes: a screen-scraping
+interface called the "simple API", and XML-RPC.  The first one uses HTML pages
+located under http://pypi.python.org/simple/, the second one makes XML-RPC
+requests to http://pypi.python.org/pypi/.  All functions and classes also work
+with other indexes such as mirrors, which typically implement only the simple
+interface.
+
+Packaging provides a class that wraps both APIs to provide full query and
+download functionality: :class:`packaging.pypi.client.ClientWrapper`.  If you
+want more control, you can use the underlying classes
+:class:`packaging.pypi.simple.Crawler` and :class:`packaging.pypi.xmlrpc.Client`
+to connect to one specific interface.
+
+
+:mod:`packaging.pypi.client` --- High-level query API
+=====================================================
+
+.. module:: packaging.pypi.client
+   :synopsis: Wrapper around :mod;`packaging.pypi.xmlrpc` and
+              :mod:`packaging.pypi.simple` to query indexes.
+
+
+This module provides a high-level API to query indexes and search
+for releases and distributions. The aim of this module is to choose the best
+way to query the API automatically, either using XML-RPC or the simple index,
+with a preference toward the latter.
+
+.. class:: ClientWrapper
+
+   Instances of this class will use the simple interface or XML-RPC requests to
+   query indexes and return :class:`packaging.pypi.dist.ReleaseInfo` and
+   :class:`packaging.pypi.dist.ReleasesList` objects.

+==========================================================================
+
+.. module:: packaging.pypi.simple
+   :synopsis: Crawler using the screen-scraping "simple" interface to fetch info
+              and distributions.
+
+
+`packaging.pypi.simple` can process Python Package Indexes  and provides
+useful information about distributions. It also can crawl local indexes, for
+instance.
+
+You should use `packaging.pypi.simple` for:
+
+    * Search distributions by name and versions.
+    * Process index external pages.
+    * Download distributions by name and versions.
+
+And should not be used for:
+
+    * Things that will end up in too long index processing (like "finding all
+      distributions with a specific version, no matters the name")
+
+
+API
+---
+
+.. class:: Crawler
+
+
+Usage Exemples
+---------------
+
+To help you understand how using the `Crawler` class, here are some basic
+usages.
+
+Request the simple index to get a specific distribution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Supposing you want to scan an index to get a list of distributions for
+the "foobar" project. You can use the "get_releases" method for that.
+The get_releases method will browse the project page, and return
+:class:`ReleaseInfo`  objects for each found link that rely on downloads. ::
+
+   >>> from packaging.pypi.simple import Crawler
+   >>> crawler = Crawler()
+   >>> crawler.get_releases("FooBar")
+   [<ReleaseInfo "Foobar 1.1">, <ReleaseInfo "Foobar 1.2">]
+
+
+Note that you also can request the client about specific versions, using version
+specifiers (described in `PEP 345
+<http://www.python.org/dev/peps/pep-0345/#version-specifiers>`_)::
+
+   >>> client.get_releases("FooBar < 1.2")
+   [<ReleaseInfo "FooBar 1.1">, ]
+
+
+`get_releases` returns a list of :class:`ReleaseInfo`, but you also can get the
+best distribution that fullfil your requirements, using "get_release"::
+
+   >>> client.get_release("FooBar < 1.2")
+   <ReleaseInfo "FooBar 1.1">
+
+
+Download distributions
+^^^^^^^^^^^^^^^^^^^^^^
+
+As it can get the urls of distributions provided by PyPI, the `Crawler`
+client also can download the distributions and put it for you in a temporary
+destination::
+
+   >>> client.download("foobar")
+   /tmp/temp_dir/foobar-1.2.tar.gz
+
+
+You also can specify the directory you want to download to::
+
+   >>> client.download("foobar", "/path/to/my/dir")
+   /path/to/my/dir/foobar-1.2.tar.gz
+
+
+While downloading, the md5 of the archive will be checked, if not matches, it
+will try another time, then if fails again, raise `MD5HashDoesNotMatchError`.
+
+Internally, that's not the Crawler which download the distributions, but the
+`DistributionInfo` class. Please refer to this documentation for more details.
+
+
+Following PyPI external links
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The default behavior for packaging is to *not* follow the links provided
+by HTML pages in the "simple index", to find distributions related
+downloads.
+
+It's possible to tell the PyPIClient to follow external links by setting the
+`follow_externals` attribute, on instantiation or after::
+
+   >>> client = Crawler(follow_externals=True)
+
+or ::
+
+   >>> client = Crawler()
+   >>> client.follow_externals = True
+
+
+Working with external indexes, and mirrors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The default `Crawler` behavior is to rely on the Python Package index stored
+on PyPI (http://pypi.python.org/simple).
+
+As you can need to work with a local index, or private indexes, you can specify
+it using the index_url parameter::
+
+   >>> client = Crawler(index_url="file://filesystem/path/")
+
+or ::
+
+   >>> client = Crawler(index_url="http://some.specific.url/")
+
+
+You also can specify mirrors to fallback on in case the first index_url you
+provided doesnt respond, or not correctly. The default behavior for
+`Crawler` is to use the list provided by Python.org DNS records, as
+described in the :PEP:`381` about mirroring infrastructure.
+
+If you don't want to rely on these, you could specify the list of mirrors you
+want to try by specifying the `mirrors` attribute. It's a simple iterable::
+
+   >>> mirrors = ["http://first.mirror","http://second.mirror"]
+   >>> client = Crawler(mirrors=mirrors)
+
+
+Searching in the simple index
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It's possible to search for projects with specific names in the package index.
+Assuming you want to find all projects containing the "distutils" keyword::
+
+   >>> c.search_projects("distutils")
+   [<Project "collective.recipe.distutils">, <Project "Distutils">, <Project
+   "Packaging">, <Project "distutilscross">, <Project "lpdistutils">, <Project
+   "taras.recipe.distutils">, <Project "zerokspot.recipe.distutils">]
+
+
+You can also search the projects starting with a specific text, or ending with
+that text, using a wildcard::
+
+   >>> c.search_projects("distutils*")
+   [<Project "Distutils">, <Project "Packaging">, <Project "distutilscross">]
+
+   >>> c.search_projects("*distutils")
+   [<Project "collective.recipe.distutils">, <Project "Distutils">, <Project
+   "lpdistutils">, <Project "taras.recipe.distutils">, <Project
+   "zerokspot.recipe.distutils">]

+=========================================================================
+
+.. module:: packaging.pypi.xmlrpc
+   :synopsis: Client using XML-RPC requests to fetch info and distributions.
+
+
+Indexes can be queried using XML-RPC calls, and Packaging provides a simple
+way to interface with XML-RPC.
+
+You should **use** XML-RPC when:
+
+* Searching the index for projects **on other fields than project
+  names**. For instance, you can search for projects based on the
+  author_email field.
+* Searching all the versions that have existed for a project.
+* you want to retrieve METADATAs information from releases or
+  distributions.
+
+
+You should **avoid using** XML-RPC method calls when:
+
+* Retrieving the last version of a project
+* Getting the projects with a specific name and version.
+* The simple index can match your needs
+
+
+When dealing with indexes, keep in mind that the index queries will always
+return you :class:`packaging.pypi.dist.ReleaseInfo` and
+:class:`packaging.pypi.dist.ReleasesList` objects.
+
+Some methods here share common APIs with the one you can find on
+:class:`packaging.pypi.simple`, internally, :class:`packaging.pypi.client`
+is inherited by :class:`Client`
+
+
+API
+---
+
+.. class:: Client
+
+
+Usage examples
+--------------
+
+Use case described here are use case that are not common to the other clients.
+If you want to see all the methods, please refer to API or to usage examples
+described in :class:`packaging.pypi.client.Client`
+
+
+Finding releases
+^^^^^^^^^^^^^^^^
+
+It's a common use case to search for "things" within the index. We can
+basically search for projects by their name, which is the most used way for
+users (eg. "give me the last version of the FooBar project").
+
+This can be accomplished using the following syntax::
+
+   >>> client = xmlrpc.Client()
+   >>> client.get_release("Foobar (<= 1.3))
+   <FooBar 1.2.1>
+   >>> client.get_releases("FooBar (<= 1.3)")
+   [FooBar 1.1, FooBar 1.1.1, FooBar 1.2, FooBar 1.2.1]
+
+
+And we also can find for specific fields::
+
+   >>> client.search_projects(field=value)
+
+
+You could specify the operator to use, default is "or"::
+
+   >>> client.search_projects(field=value, operator="and")
+
+
+The specific fields you can search are:
+
+* name
+* version
+* author
+* author_email
+* maintainer
+* maintainer_email
+* home_page
+* license
+* summary
+* description
+* keywords
+* platform
+* download_url
+
+
+Getting metadata information
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+XML-RPC is a prefered way to retrieve metadata information from indexes.
+It's really simple to do so::
+
+   >>> client = xmlrpc.Client()
+   >>> client.get_metadata("FooBar", "1.1")
+   <ReleaseInfo FooBar 1.1>
+
+
+Assuming we already have a :class:`packaging.pypi.ReleaseInfo` object defined,
+it's possible to pass it to the xmlrpc client to retrieve and complete its
+metadata::
+
+   >>> foobar11 = ReleaseInfo("FooBar", "1.1")
+   >>> client = xmlrpc.Client()
+   >>> returned_release = client.get_metadata(release=foobar11)
+   >>> returned_release
+   <ReleaseInfo FooBar 1.1>
+
+
+Get all the releases of a project
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To retrieve all the releases for a project, you can build them using
+`get_releases`::
+
+   >>> client = xmlrpc.Client()
+   >>> client.get_releases("FooBar")
+   [<ReleaseInfo FooBar 0.9>, <ReleaseInfo FooBar 1.0>, <ReleaseInfo 1.1>]
+
+
+Get information about distributions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Indexes have information about projects, releases **and** distributions.
+If you're not familiar with those, please refer to the documentation of
+:mod:`packaging.pypi.dist`.
+
+It's possible to retrieve information about distributions, e.g "what are the
+existing distributions for this release ? How to retrieve them ?"::
+
+   >>> client = xmlrpc.Client()
+   >>> release = client.get_distributions("FooBar", "1.1")
+   >>> release.dists
+   {'sdist': <FooBar 1.1 sdist>, 'bdist': <FooBar 1.1 bdist>}
+
+As you see, this does not return a list of distributions, but a release,
+because a release can be used like a list of distributions.

+
+
+The :mod:`packaging` package provides support for building, packaging,
+distributing and installing additional projects into a Python installation.
+Projects may include Python modules, extension modules, packages and scripts.
+:mod:`packaging` also provides building blocks for other packaging systems

+:mod:`packaging.tests.pypi_server` --- PyPI mock server
+=======================================================
+
+.. module:: packaging.tests.pypi_server
+   :synopsis: Mock server used to test PyPI-related modules and commands.
+
+
+When you are testing code that works with Packaging, you might find these tools
+useful.
+
+
+The mock server
+---------------
+
+.. class:: PyPIServer
+
+   PyPIServer is a class that implements an HTTP server running in a separate
+   thread. All it does is record the requests for further inspection. The recorded
+   data is available under ``requests`` attribute. The default
+   HTTP response can be overridden with the ``default_response_status``,
+   ``default_response_headers`` and ``default_response_data`` attributes.
+
+   By default, when accessing the server with urls beginning with `/simple/`,
+   the server also record your requests, but will look for files under
+   the `/tests/pypiserver/simple/` path.
+
+   You can tell the sever to serve static files for other paths. This could be
+   accomplished by using the `static_uri_paths` parameter, as below::
+
+      server = PyPIServer(static_uri_paths=["first_path", "second_path"])
+
+
+   You need to create the content that will be served under the
+   `/tests/pypiserver/default` path. If you want to serve content from another
+   place, you also can specify another filesystem path (which needs to be under
+   `tests/pypiserver/`. This will replace the default behavior of the server, and
+   it will not serve content from the `default` dir ::
+
+      server = PyPIServer(static_filesystem_paths=["path/to/your/dir"])
+
+
+   If you just need to add some paths to the existing ones, you can do as shown,
+   keeping in mind that the server will always try to load paths in reverse order
+   (e.g here, try "another/super/path" then the default one) ::
+
+      server = PyPIServer(test_static_path="another/super/path")
+      server = PyPIServer("another/super/path")
+      # or
+      server.static_filesystem_paths.append("another/super/path")
+
+
+   As a result of what, in your tests, while you need to use the PyPIServer, in
+   order to isolates the test cases, the best practice is to place the common files
+   in the `default` folder, and to create a directory for each specific test case::
+
+      server = PyPIServer(static_filesystem_paths = ["default", "test_pypi_server"],
+                          static_uri_paths=["simple", "external"])
+
+
+Base class and decorator for tests
+----------------------------------
+
+.. class:: PyPIServerTestCase
+
+   ``PyPIServerTestCase`` is a test case class with setUp and tearDown methods that
+   take care of a single PyPIServer instance attached as a ``pypi`` attribute on
+   the test class. Use it as one of the base classes in your test case::
+
+
+      class UploadTestCase(PyPIServerTestCase):
+
+          def test_something(self):
+              cmd = self.prepare_command()
+              cmd.ensure_finalized()
+              cmd.repository = self.pypi.full_address
+              cmd.run()
+
+              environ, request_data = self.pypi.requests[-1]
+              self.assertEqual(request_data, EXPECTED_REQUEST_DATA)
+
+
+.. decorator:: use_pypi_server
+
+   You also can use a decorator for your tests, if you do not need the same server
+   instance along all you test case. So, you can specify, for each test method,
+   some initialisation parameters for the server.
+
+   For this, you need to add a `server` parameter to your method, like this::
+
+      class SampleTestCase(TestCase):
+
+          @use_pypi_server()
+          def test_something(self, server):
+              ...
+
+
+   The decorator will instantiate the server for you, and run and stop it just
+   before and after your method call. You also can pass the server initializer,
+   just like this::
+
+      class SampleTestCase(TestCase):
+
+          @use_pypi_server("test_case_name")
+          def test_something(self, server):
+              ...

+:mod:`packaging.util` --- Miscellaneous utility functions
+=========================================================
+
+.. module:: packaging.util
+   :synopsis: Miscellaneous utility functions.
+
+
+This module contains various helpers for the other modules.
+
+.. XXX a number of functions are missing, but the module may be split first
+   (it's ginormous right now, some things could go to compat for example)
+
+.. function:: get_platform()
+
+   Return a string that identifies the current platform.  This is used mainly to
+   distinguish platform-specific build directories and platform-specific built
+   distributions.  Typically includes the OS name and version and the
+   architecture (as supplied by 'os.uname()'), although the exact information
+   included depends on the OS; e.g. for IRIX the architecture isn't particularly
+   important (IRIX only runs on SGI hardware), but for Linux the kernel version
+   isn't particularly important.
+
+   Examples of returned values:
+
+   * ``linux-i586``
+   * ``linux-alpha``
+   * ``solaris-2.6-sun4u``
+   * ``irix-5.3``
+   * ``irix64-6.2``
+
+   For non-POSIX platforms, currently just returns ``sys.platform``.
+
+   For Mac OS X systems the OS version reflects the minimal version on which
+   binaries will run (that is, the value of ``MACOSX_DEPLOYMENT_TARGET``
+   during the build of Python), not the OS version of the current system.
+
+   For universal binary builds on Mac OS X the architecture value reflects
+   the univeral binary status instead of the architecture of the current
+   processor. For 32-bit universal binaries the architecture is ``fat``,
+   for 64-bit universal binaries the architecture is ``fat64``, and
+   for 4-way universal binaries the architecture is ``universal``. Starting
+   from Python 2.7 and Python 3.2 the architecture ``fat3`` is used for
+   a 3-way universal build (ppc, i386, x86_64) and ``intel`` is used for
+   a univeral build with the i386 and x86_64 architectures
+
+   Examples of returned values on Mac OS X:
+
+   * ``macosx-10.3-ppc``
+
+   * ``macosx-10.3-fat``
+
+   * ``macosx-10.5-universal``
+
+   * ``macosx-10.6-intel``
+
+   .. XXX reinvention of platform module?
+
+
+.. function:: convert_path(pathname)
+
+   Return 'pathname' as a name that will work on the native filesystem, i.e.
+   split it on '/' and put it back together again using the current directory
+   separator. Needed because filenames in the setup script are always supplied
+   in Unix style, and have to be converted to the local convention before we
+   can actually use them in the filesystem.  Raises :exc:`ValueError` on
+   non-Unix-ish systems if *pathname* either starts or ends with a slash.
+
+
+.. function:: change_root(new_root, pathname)
+
+   Return *pathname* with *new_root* prepended.  If *pathname* is relative, this
+   is equivalent to ``os.path.join(new_root,pathname)`` Otherwise, it requires
+   making *pathname* relative and then joining the two, which is tricky on
+   DOS/Windows.
+
+
+.. function:: check_environ()
+
+   Ensure that 'os.environ' has all the environment variables we guarantee that
+   users can use in config files, command-line options, etc.  Currently this
+   includes:
+
+   * :envvar:`HOME` - user's home directory (Unix only)
+   * :envvar:`PLAT` - description of the current platform, including hardware
+     and OS (see :func:`get_platform`)
+
+
+.. function:: find_executable(executable, path=None)
+
+   Search the path for a given executable name.
+
+
+.. function:: subst_vars(s, local_vars)
+
+   Perform shell/Perl-style variable substitution on *s*.  Every occurrence of
+   ``$`` followed by a name is considered a variable, and variable is
+   substituted by the value found in the *local_vars* dictionary, or in
+   ``os.environ`` if it's not in *local_vars*. *os.environ* is first
+   checked/augmented to guarantee that it contains certain values: see
+   :func:`check_environ`.  Raise :exc:`ValueError` for any variables not found
+   in either *local_vars* or ``os.environ``.
+
+   Note that this is not a fully-fledged string interpolation function. A valid
+   ``$variable`` can consist only of upper and lower case letters, numbers and
+   an underscore. No { } or ( ) style quoting is available.
+
+
+.. function:: split_quoted(s)
+
+   Split a string up according to Unix shell-like rules for quotes and
+   backslashes. In short: words are delimited by spaces, as long as those spaces
+   are not escaped by a backslash, or inside a quoted string. Single and double
+   quotes are equivalent, and the quote characters can be backslash-escaped.
+   The backslash is stripped from any two-character escape sequence, leaving
+   only the escaped character.  The quote characters are stripped from any
+   quoted string.  Returns a list of words.
+
+   .. TODO Should probably be moved into the standard library.
+
+
+.. function:: execute(func, args[, msg=None, verbose=0, dry_run=0])
+
+   Perform some action that affects the outside world (for instance, writing to
+   the filesystem).  Such actions are special because they are disabled by the
+   *dry_run* flag.  This method takes care of all that bureaucracy for you;
+   all you have to do is supply the function to call and an argument tuple for
+   it (to embody the "external action" being performed), and an optional message
+   to print.
+
+
+.. function:: newer(source, target)
+
+   Return true if *source* exists and is more recently modified than *target*,
+   or if *source* exists and *target* doesn't. Return false if both exist and
+   *target* is the same age or newer than *source*. Raise
+   :exc:`PackagingFileError` if *source* does not exist.
+
+
+.. function:: strtobool(val)
+
+   Convert a string representation of truth to true (1) or false (0).
+
+   True values are ``y``, ``yes``, ``t``, ``true``, ``on`` and ``1``; false
+   values are ``n``, ``no``, ``f``, ``false``, ``off`` and ``0``.  Raises
+   :exc:`ValueError` if *val* is anything else.
+
+.. TODO Add :term: markup to bytecode when merging into the stdlib
+
+.. function:: byte_compile(py_files[, optimize=0, force=0, prefix=None, base_dir=None, verbose=1, dry_run=0, direct=None])
+
+   Byte-compile a collection of Python source files to either :file:`.pyc` or
+   :file:`.pyo` files in the same directory.  *py_files* is a list of files to
+   compile; any files that don't end in :file:`.py` are silently skipped.
+   *optimize* must be one of the following:
+
+   * ``0`` - don't optimize (generate :file:`.pyc`)
+   * ``1`` - normal optimization (like ``python -O``)
+   * ``2`` - extra optimization (like ``python -OO``)
+
+   If *force* is true, all files are recompiled regardless of timestamps.
+
+   The source filename encoded in each bytecode file defaults to the filenames
+   listed in *py_files*; you can modify these with *prefix* and *basedir*.
+   *prefix* is a string that will be stripped off of each source filename, and
+   *base_dir* is a directory name that will be prepended (after *prefix* is
+   stripped).  You can supply either or both (or neither) of *prefix* and
+   *base_dir*, as you wish.
+
+   If *dry_run* is true, doesn't actually do anything that would affect the
+   filesystem.
+
+   Byte-compilation is either done directly in this interpreter process with the
+   standard :mod:`py_compile` module, or indirectly by writing a temporary
+   script and executing it.  Normally, you should let :func:`byte_compile`
+   figure out to use direct compilation or not (see the source for details).
+   The *direct* flag is used by the script generated in indirect mode; unless
+   you know what you're doing, leave it set to ``None``.
+
+
+.. function:: rfc822_escape(header)
+
+   Return a version of *header* escaped for inclusion in an :rfc:`822` header, by
+   ensuring there are 8 spaces space after each newline.  Note that it does no
+   other modification of the string.
+
+   .. TODO this _can_ be replaced

+:mod:`packaging.version` --- Version number classes
+===================================================
+
+.. module:: packaging.version
+   :synopsis: Classes that represent project version numbers.
+
+
+This module contains classes and functions useful to deal with version numbers.
+It's an implementation of version specifiers `as defined in PEP 345
+<http://www.python.org/dev/peps/pep-0345/#version-specifiers>`_.
+
+
+Version numbers
+---------------
+
+.. class:: NormalizedVersion(self, s, error_on_huge_major_num=True)
+
+   A specific version of a distribution, as described in PEP 345.  *s* is a
+   string object containing the version number (for example ``'1.2b1'``),
+   *error_on_huge_major_num* a boolean specifying whether to consider an
+   apparent use of a year or full date as the major version number an error.
+
+   The rationale for the second argument is that there were projects using years
+   or full dates as version numbers, which could cause problems with some
+   packaging systems sorting.
+
+   Instances of this class can be compared and sorted::
+
+      >>> NormalizedVersion('1.2b1') < NormalizedVersion('1.2')
+      True
+
+   :class:`NormalizedVersion` is used internally by :class:`VersionPredicate` to
+   do its work.
+
+
+.. class:: IrrationalVersionError
+
+   Exception raised when an invalid string is given to
+   :class:`NormalizedVersion`.
+
+      >>> NormalizedVersion("irrational_version_number")
+      ...
+      IrrationalVersionError: irrational_version_number
+
+
+.. function:: suggest_normalized_version(s)
+
+   Before standardization in PEP 386, various schemes were in use.  Packaging
+   provides a function to try to convert any string to a valid, normalized
+   version::
+
+      >>> suggest_normalized_version('2.1-rc1')
+      2.1c1
+
+
+   If :func:`suggest_normalized_version` can't make sense of the given string,
+   it will return ``None``::
+
+      >>> print(suggest_normalized_version('not a version'))
+      None
+
+
+Version predicates
+------------------
+
+.. class:: VersionPredicate(predicate)
+
+   This class deals with the parsing of field values like
+   ``ProjectName (>=version)``.
+
+   .. method:: match(version)
+
+      Test if a version number matches the predicate:
+
+         >>> version = VersionPredicate("ProjectName (<1.2, >1.0)")
+         >>> version.match("1.2.1")
+         False
+         >>> version.match("1.1.1")
+         True
+
+
+Validation helpers
+------------------
+
+If you want to use :term:`LBYL`-style checks instead of instantiating the
+classes and catching :class:`IrrationalVersionError` and :class:`ValueError`,
+you can use these functions:
+
+.. function:: is_valid_version(predicate)
+
+   Check whether the given string is a valid version number.  Example of valid
+   strings: ``'1.2'``,  ``'4.2.0.dev4'``, ``'2.5.4.post2'``.
+
+
+.. function:: is_valid_versions(predicate)
+
+   Check whether the given string is a valid value for specifying multiple
+   versions, such as in the Requires-Python field.  Example: ``'2.7, >=3.2'``.
+
+
+.. function:: is_valid_predicate(predicate)
+
+   Check whether the given string is a valid version predicate.  Examples:
+   ``'some.project == 4.5, <= 4.7'``, ``'speciallib (> 1.0, != 1.4.2, < 2.0)'``.

+
+****************************
+Creating Built Distributions
+****************************
+
+A "built distribution" is what you're probably used to thinking of either as a
+"binary package" or an "installer" (depending on your background).  It's not
+necessarily binary, though, because it might contain only Python source code
+and/or byte-code; and we don't call it a package, because that word is already
+spoken for in Python.  (And "installer" is a term specific to the world of
+mainstream desktop systems.)
+
+A built distribution is how you make life as easy as possible for installers of
+your module distribution: for users of RPM-based Linux systems, it's a binary
+RPM; for Windows users, it's an executable installer; for Debian-based Linux
+users, it's a Debian package; and so forth.  Obviously, no one person will be
+able to create built distributions for every platform under the sun, so the
+Distutils are designed to enable module developers to concentrate on their
+specialty---writing code and creating source distributions---while an
+intermediary species called *packagers* springs up to turn source distributions
+into built distributions for as many platforms as there are packagers.
+
+Of course, the module developer could be his own packager; or the packager could
+be a volunteer "out there" somewhere who has access to a platform which the
+original developer does not; or it could be software periodically grabbing new
+source distributions and turning them into built distributions for as many
+platforms as the software has access to.  Regardless of who they are, a packager
+uses the setup script and the :command:`bdist` command family to generate built
+distributions.
+
+As a simple example, if I run the following command in the Distutils source
+tree::
+
+   python setup.py bdist
+
+then the Distutils builds my module distribution (the Distutils itself in this
+case), does a "fake" installation (also in the :file:`build` directory), and
+creates the default type of built distribution for my platform.  The default
+format for built distributions is a "dumb" tar file on Unix, and a simple
+executable installer on Windows.  (That tar file is considered "dumb" because it
+has to be unpacked in a specific location to work.)
+
+Thus, the above command on a Unix system creates
+:file:`Distutils-1.0.{plat}.tar.gz`; unpacking this tarball from the right place
+installs the Distutils just as though you had downloaded the source distribution
+and run ``python setup.py install``.  (The "right place" is either the root of
+the filesystem or  Python's :file:`{prefix}` directory, depending on the options
+given to the :command:`bdist_dumb` command; the default is to make dumb
+distributions relative to :file:`{prefix}`.)
+
+Obviously, for pure Python distributions, this isn't any simpler than just
+running ``python setup.py install``\ ---but for non-pure distributions, which
+include extensions that would need to be compiled, it can mean the difference
+between someone being able to use your extensions or not.  And creating "smart"
+built distributions, such as an executable installer for
+Windows, is far more convenient for users even if your distribution doesn't
+include any extensions.
+
+The :command:`bdist` command has a :option:`--formats` option, similar to the
+:command:`sdist` command, which you can use to select the types of built
+distribution to generate: for example, ::
+
+   python setup.py bdist --format=zip
+
+would, when run on a Unix system, create :file:`Distutils-1.0.{plat}.zip`\
+---again, this archive would be unpacked from the root directory to install the
+Distutils.
+
+The available formats for built distributions are:
+
++-------------+------------------------------+---------+
+| Format      | Description                  | Notes   |
++=============+==============================+=========+
+| ``gztar``   | gzipped tar file             | (1),(3) |
+|             | (:file:`.tar.gz`)            |         |
++-------------+------------------------------+---------+
+| ``ztar``    | compressed tar file          | \(3)    |
+|             | (:file:`.tar.Z`)             |         |
++-------------+------------------------------+---------+
+| ``tar``     | tar file (:file:`.tar`)      | \(3)    |
++-------------+------------------------------+---------+
+| ``zip``     | zip file (:file:`.zip`)      | (2),(4) |
++-------------+------------------------------+---------+
+| ``wininst`` | self-extracting ZIP file for | \(4)    |
+|             | Windows                      |         |
++-------------+------------------------------+---------+
+| ``msi``     | Microsoft Installer.         |         |
++-------------+------------------------------+---------+
+
+
+Notes:
+
+(1)
+   default on Unix
+
+(2)
+   default on Windows
+
+(3)
+   requires external utilities: :program:`tar` and possibly one of :program:`gzip`,
+   :program:`bzip2`, or :program:`compress`
+
+(4)
+   requires either external :program:`zip` utility or :mod:`zipfile` module (part
+   of the standard Python library since Python 1.6)
+
+You don't have to use the :command:`bdist` command with the :option:`--formats`
+option; you can also use the command that directly implements the format you're
+interested in.  Some of these :command:`bdist` "sub-commands" actually generate
+several similar formats; for instance, the :command:`bdist_dumb` command
+generates all the "dumb" archive formats (``tar``, ``ztar``, ``gztar``, and
+``zip``).  The :command:`bdist` sub-commands, and the formats generated by
+each, are:
+
++--------------------------+-----------------------+
+| Command                  | Formats               |
++==========================+=======================+
+| :command:`bdist_dumb`    | tar, ztar, gztar, zip |
++--------------------------+-----------------------+
+| :command:`bdist_wininst` | wininst               |
++--------------------------+-----------------------+

++--------------------------+-----------------------+
+
+The following sections give details on the individual :command:`bdist_\*`
+commands.
+
+
+.. _packaging-creating-dumb:
+
+Creating dumb built distributions
+=================================
+
+.. XXX Need to document absolute vs. prefix-relative packages here, but first
+       I have to implement it!
+
+
+.. _packaging-creating-wininst:
+
+Creating Windows Installers
+===========================
+
+Executable installers are the natural format for binary distributions on
+Windows.  They display a nice graphical user interface, display some information
+about the module distribution to be installed taken from the metadata in the
+setup script, let the user select a few options, and start or cancel the
+installation.
+
+Since the metadata is taken from the setup script, creating Windows installers
+is usually as easy as running::
+
+   python setup.py bdist_wininst
+
+or the :command:`bdist` command with the :option:`--formats` option::
+
+   python setup.py bdist --formats=wininst
+
+If you have a pure module distribution (only containing pure Python modules and
+packages), the resulting installer will be version independent and have a name
+like :file:`foo-1.0.win32.exe`.  These installers can even be created on Unix
+platforms or Mac OS X.
+
+If you have a non-pure distribution, the extensions can only be created on a
+Windows platform, and will be Python version dependent. The installer filename
+will reflect this and now has the form :file:`foo-1.0.win32-py2.0.exe`.  You
+have to create a separate installer for every Python version you want to
+support.
+
+.. TODO Add :term: markup to bytecode when merging into the stdlib
+
+The installer will try to compile pure modules into bytecode after installation
+on the target system in normal and optimizing mode.  If you don't want this to
+happen for some reason, you can run the :command:`bdist_wininst` command with
+the :option:`--no-target-compile` and/or the :option:`--no-target-optimize`
+option.
+
+By default the installer will display the cool "Python Powered" logo when it is
+run, but you can also supply your own 152x261 bitmap which must be a Windows
+:file:`.bmp` file with the :option:`--bitmap` option.
+
+The installer will also display a large title on the desktop background window
+when it is run, which is constructed from the name of your distribution and the
+version number.  This can be changed to another text by using the
+:option:`--title` option.
+
+The installer file will be written to the "distribution directory" --- normally
+:file:`dist/`, but customizable with the :option:`--dist-dir` option.
+
+.. _packaging-cross-compile-windows:
+
+Cross-compiling on Windows
+==========================
+
+Starting with Python 2.6, packaging is capable of cross-compiling between
+Windows platforms.  In practice, this means that with the correct tools
+installed, you can use a 32bit version of Windows to create 64bit extensions
+and vice-versa.
+
+To build for an alternate platform, specify the :option:`--plat-name` option
+to the build command.  Valid values are currently 'win32', 'win-amd64' and
+'win-ia64'.  For example, on a 32bit version of Windows, you could execute::
+
+   python setup.py build --plat-name=win-amd64
+
+to build a 64bit version of your extension.  The Windows Installers also
+support this option, so the command::
+
+   python setup.py build --plat-name=win-amd64 bdist_wininst
+
+would create a 64bit installation executable on your 32bit version of Windows.
+
+To cross-compile, you must download the Python source code and cross-compile
+Python itself for the platform you are targetting - it is not possible from a
+binary installtion of Python (as the .lib etc file for other platforms are
+not included.)  In practice, this means the user of a 32 bit operating
+system will need to use Visual Studio 2008 to open the
+:file:`PCBuild/PCbuild.sln` solution in the Python source tree and build the
+"x64" configuration of the 'pythoncore' project before cross-compiling
+extensions is possible.
+
+Note that by default, Visual Studio 2008 does not install 64bit compilers or
+tools.  You may need to reexecute the Visual Studio setup process and select
+these tools (using Control Panel->[Add/Remove] Programs is a convenient way to
+check or modify your existing install.)
+
+.. _packaging-postinstallation-script:
+
+The Postinstallation script
+---------------------------
+
+Starting with Python 2.3, a postinstallation script can be specified with the
+:option:`--install-script` option.  The basename of the script must be
+specified, and the script filename must also be listed in the scripts argument
+to the setup function.
+
+This script will be run at installation time on the target system after all the
+files have been copied, with ``argv[1]`` set to :option:`-install`, and again at
+uninstallation time before the files are removed with ``argv[1]`` set to
+:option:`-remove`.
+
+The installation script runs embedded in the windows installer, every output
+(``sys.stdout``, ``sys.stderr``) is redirected into a buffer and will be
+displayed in the GUI after the script has finished.
+
+Some functions especially useful in this context are available as additional
+built-in functions in the installation script.
+
+.. currentmodule:: bdist_wininst-postinst-script
+
+.. function:: directory_created(path)
+              file_created(path)
+
+   These functions should be called when a directory or file is created by the
+   postinstall script at installation time.  It will register *path* with the
+   uninstaller, so that it will be removed when the distribution is uninstalled.
+   To be safe, directories are only removed if they are empty.
+
+
+.. function:: get_special_folder_path(csidl_string)
+
+   This function can be used to retrieve special folder locations on Windows like
+   the Start Menu or the Desktop.  It returns the full path to the folder.
+   *csidl_string* must be one of the following strings::
+
+      "CSIDL_APPDATA"
+
+      "CSIDL_COMMON_STARTMENU"
+      "CSIDL_STARTMENU"
+
+      "CSIDL_COMMON_DESKTOPDIRECTORY"
+      "CSIDL_DESKTOPDIRECTORY"
+
+      "CSIDL_COMMON_STARTUP"
+      "CSIDL_STARTUP"
+
+      "CSIDL_COMMON_PROGRAMS"
+      "CSIDL_PROGRAMS"
+
+      "CSIDL_FONTS"
+
+   If the folder cannot be retrieved, :exc:`OSError` is raised.
+
+   Which folders are available depends on the exact Windows version, and probably
+   also the configuration.  For details refer to Microsoft's documentation of the
+   c:function:`SHGetSpecialFolderPath` function.
+
+
+.. function:: create_shortcut(target, description, filename[, arguments[, workdir[, iconpath[, iconindex]]]])
+
+   This function creates a shortcut. *target* is the path to the program to be
+   started by the shortcut. *description* is the description of the shortcut.
+   *filename* is the title of the shortcut that the user will see. *arguments*
+   specifies the command-line arguments, if any. *workdir* is the working directory
+   for the program. *iconpath* is the file containing the icon for the shortcut,
+   and *iconindex* is the index of the icon in the file *iconpath*.  Again, for
+   details consult the Microsoft documentation for the :class:`IShellLink`
+   interface.
+
+
+Vista User Access Control (UAC)
+===============================
+
+Starting with Python 2.6, bdist_wininst supports a :option:`--user-access-control`
+option.  The default is 'none' (meaning no UAC handling is done), and other
+valid values are 'auto' (meaning prompt for UAC elevation if Python was
+installed for all users) and 'force' (meaning always prompt for elevation).

+=============
+Command hooks
+=============
+
+Packaging provides a way of extending its commands by the use of pre- and
+post- command hooks. The hooks are simple Python functions (or any callable
+objects) and are specified in the config file using their full qualified names.
+The pre-hooks are run after the command is finalized (its options are
+processed), but before it is run. The post-hooks are run after the command
+itself. Both types of hooks receive an instance of the command object.
+
+Sample usage of hooks
+=====================
+
+Firstly, you need to make sure your hook is present in the path. This is usually
+done by dropping them to the same folder where `setup.py` file lives ::
+
+  # file: myhooks.py
+  def my_install_hook(install_cmd):
+      print "Oh la la! Someone is installing my project!"
+
+Then, you need to point to it in your `setup.cfg` file, under the appropriate
+command section ::
+
+  [install_dist]
+  pre-hook.project = myhooks.my_install_hook
+
+The hooks defined in different config files (system-wide, user-wide and
+package-wide) do not override each other as long as they are specified with
+different aliases (additional names after the dot). The alias in the example
+above is ``project``.

+their options.
+

+   standard and extra commands availavble on your system, with their
+   description.  Use pysetup run <command> --help to get help about the options
+   of one command.
+
+
+Preparing distributions
+=======================
+
+:command:`check`
+----------------
+
+Perform some tests on the metadata of a distribution.
+
+For example, it verifies that all required metadata fields are provided in the
+:file:`setup.cfg` file.
+
+.. TODO document reST checks
+
+
+:command:`test`
+---------------
+
+Run a test suite.
+
+When doing test-driven development, or running automated builds that need
+testing before they are installed for downloading or use, it's often useful to
+be able to run a project's unit tests without actually installing the project
+anywhere.  The :command:`test` command runs project's unit tests without
+actually installing it, by temporarily putting the project's source on
+:data:`sys.path`, after first running :command:`build_ext -i` to ensure that any
+C extensions are built.
+
+You can use this command in one of two ways: either by specifying a
+unittest-compatible test suite for your project (or any callable that returns
+it) or by passing a test runner function that will run your tests and display
+results in the console.  Both options take a Python dotted name in the form
+``package.module.callable`` to specify the object to use.
+
+If none of these options are specified, Packaging will try to perform test
+discovery using either unittest (for Python 3.2 and higher) or unittest2 (for
+older versions, if installed).
+
+.. this is a pseudo-command name used to disambiguate the options in indexes and
+   links
+.. program:: packaging test
+
+.. cmdoption:: --suite=NAME, -s NAME
+
+   Specify the test suite (or module, class, or method) to be run.  The default
+   for this option can be set by in the project's :file:`setup.cfg` file::
+
+   .. code-block:: cfg
+
+      [test]
+      suite = mypackage.tests.get_all_tests
+
+.. cmdoption:: --runner=NAME, -r NAME
+
+   Specify the test runner to be called.
+
+
+:command:`config`
+-----------------
+
+Perform distribution configuration.
+
+
+The build step
+==============
+
+This step is mainly useful to compile C/C++ libraries or extension modules.  The
+build commands can be run manually to check for syntax errors or packaging
+issues (for example if the addition of a new source file was forgotten in the
+:file:`setup.cfg` file), and is also run automatically by commands which need
+it.  Packaging checks the mtime of source and built files to avoid re-building
+if it's not necessary.
+
+
+:command:`build`
+----------------
+
+Build all files of a distribution, delegating to the other :command:`build_*`
+commands to do the work.
+
+
+:command:`build_clib`
+---------------------
+
+Build C libraries.
+
+
+:command:`build_ext`
+--------------------
+
+Build C/C++ extension modules.
+
+
+:command:`build_py`
+-------------------
+
+Build the Python modules (just copy them to the build directory) and
+byte-compile them to .pyc files.
+
+
+:command:`build_scripts`
+------------------------
+Build the scripts (just copy them to the build directory and adjust their
+shebang if they're Python scripts).
+
+
+:command:`clean`
+----------------
+
+Clean the build tree of the release.
+
+.. program:: packaging clean
+
+.. cmdoption:: --all, -a
+
+   Remove build directories for modules, scripts, etc., not only temporary build
+   by-products.
+
+
+Creating source and built distributions
+=======================================
+
+:command:`sdist`
+----------------
+
+Build a source distribution for a release.
+
+It is recommended that you always build and upload a source distribution.  Users
+of OSes with easy access to compilers and users of advanced packaging tools will
+prefer to compile from source rather than using pre-built distributions.  For
+Windows users, providing a binary installer is also recommended practice.
+
+
+:command:`bdist`
+----------------
+
+Build a binary distribution for a release.
+
+This command will call other :command:`bdist_*` commands to create one or more
+distributions depending on the options given.  The default is to create a
+.tar.gz archive on Unix and a zip archive on Windows or OS/2.
+
+.. program:: packaging bdist
+
+.. cmdoption:: --formats
+
+   Binary formats to build (comma-separated list).
+
+.. cmdoption:: --show-formats
+
+   Dump list of available formats.
+
+
+:command:`bdist_dumb`
+---------------------
+
+Build a "dumb" installer, a simple archive of files that could be unpacked under
+``$prefix`` or ``$exec_prefix``.
+
+
+:command:`bdist_wininst`
+------------------------
+
+Build a Windows installer.
+
+
+:command:`bdist_msi`
+--------------------
+
+Build a `Microsoft Installer`_ (.msi) file.
+
+.. _Microsoft Installer: http://msdn.microsoft.com/en-us/library/cc185688(VS.85).aspx
+
+In most cases, the :command:`bdist_msi` installer is a better choice than the
+:command:`bdist_wininst` installer, because it provides better support for Win64
+platforms, allows administrators to perform non-interactive installations, and
+allows installation through group policies.
+
+
+Publishing distributions
+========================
+
+:command:`register`
+-------------------
+
+This command registers the current release with the Python Package Index.  This
+is described in more detail in :PEP:`301`.
+
+.. TODO explain user and project registration with the web UI
+
+
+:command:`upload`
+-----------------
+
+Upload source and/or binary distributions to PyPI.
+
+The distributions have to be built on the same command line as the
+:command:`upload` command; see :ref:`packaging-package-upload` for more info.
+
+.. program:: packaging upload
+
+.. cmdoption:: --sign, -s
+
+   Sign each uploaded file using GPG (GNU Privacy Guard).  The ``gpg`` program
+   must be available for execution on the system ``PATH``.
+
+.. cmdoption:: --identity=NAME, -i NAME
+
+   Specify the identity or key name for GPG to use when signing.  The value of
+   this option will be passed through the ``--local-user`` option of the
+   ``gpg`` program.
+
+.. cmdoption:: --show-response
+
+   Display the full response text from server; this is useful for debugging
+   PyPI problems.
+
+.. cmdoption:: --repository=URL, -r URL
+
+   The URL of the repository to upload to.  Defaults to
+   http://pypi.python.org/pypi (i.e., the main PyPI installation).
+
+.. cmdoption:: --upload-docs
+
+   Also run :command:`upload_docs`.  Mainly useful as a default value in
+   :file:`setup.cfg` (on the command line, it's shorter to just type both
+   commands).
+
+
+:command:`upload_docs`
+----------------------
+
+Upload HTML documentation to PyPI.
+
+PyPI now supports publishing project documentation at a URI of the form
+``http://packages.python.org/<project>``.  :command:`upload_docs`  will create
+the necessary zip file out of a documentation directory and will post to the
+repository.
+
+Note that to upload the documentation of a project, the corresponding version
+must already be registered with PyPI, using the :command:`register` command ---
+just like with :command:`upload`.
+
+Assuming there is an ``Example`` project with documentation in the subdirectory
+:file:`docs`, for example::
+
+   Example/
+      example.py
+      setup.cfg
+      docs/
+         build/
+            html/
+               index.html
+               tips_tricks.html
+         conf.py
+         index.txt
+         tips_tricks.txt
+
+You can simply specify the directory with the HTML files in your
+:file:`setup.cfg` file:
+
+.. code-block:: cfg
+
+   [upload_docs]
+   upload-dir = docs/build/html
+
+
+.. program:: packaging upload_docs
+
+.. cmdoption:: --upload-dir
+
+   The directory to be uploaded to the repository. By default documentation
+   is searched for in ``docs`` (or ``doc``) directory in project root.
+
+.. cmdoption:: --show-response
+
+   Display the full response text from server; this is useful for debugging
+   PyPI problems.
+
+.. cmdoption:: --repository=URL, -r URL
+
+   The URL of the repository to upload to.  Defaults to
+   http://pypi.python.org/pypi (i.e., the main PyPI installation).
+
+
+The install step
+================
+
+These commands are used by end-users of a project using :program:`pysetup` or
+another compatible installer.  Each command will run the corresponding
+:command:`build_*` command and then move the built files to their destination on
+the target system.
+
+
+:command:`install_dist`
+-----------------------
+
+Install a distribution, delegating to the other :command:`install_*` commands to
+do the work.
+
+.. program:: packaging install_dist
+
+.. cmdoption:: --user
+
+   Install in user site-packages directory (see :PEP:`370`).
+
+
+:command:`install_data`
+-----------------------
+
+Install data files.
+
+
+:command:`install_distinfo`
+---------------------------
+
+Install files recording details of the installation as specified in :PEP:`376`.
+
+
+:command:`install_headers`
+--------------------------
+
+Install C/C++ header files.
+
+
+:command:`install_lib`
+----------------------
+
+Install C library files.
+
+
+:command:`install_scripts`
+--------------------------
+
+Install scripts.

+
+************************************
+Writing the Setup Configuration File
+************************************
+
+Often, it's not possible to write down everything needed to build a distribution
+*a priori*: you may need to get some information from the user, or from the
+user's system, in order to proceed.  As long as that information is fairly
+simple---a list of directories to search for C header files or libraries, for
+example---then providing a configuration file, :file:`setup.cfg`, for users to
+edit is a cheap and easy way to solicit it.  Configuration files also let you
+provide default values for any command option, which the installer can then
+override either on the command line or by editing the config file.
+
+The setup configuration file is a useful middle-ground between the setup script
+---which, ideally, would be opaque to installers [#]_---and the command line to
+the setup script, which is outside of your control and entirely up to the
+installer.  In fact, :file:`setup.cfg` (and any other Distutils configuration
+files present on the target system) are processed after the contents of the
+setup script, but before the command line.  This has  several useful
+consequences:
+
+.. If you have more advanced needs, such as determining which extensions to
+   build based on what capabilities are present on the target system, then you
+   need the Distutils auto-configuration facility.  This started to appear in
+   Distutils 0.9 but, as of this writing, isn't mature or stable enough yet
+   for real-world use.
+
+* installers can override some of what you put in :file:`setup.py` by editing
+  :file:`setup.cfg`
+
+* you can provide non-standard defaults for options that are not easily set in
+  :file:`setup.py`
+
+* installers can override anything in :file:`setup.cfg` using the command-line
+  options to :file:`setup.py`
+
+The basic syntax of the configuration file is simple::
+
+   [command]
+   option = value
+   ...
+
+where *command* is one of the Distutils commands (e.g. :command:`build_py`,
+:command:`install_dist`), and *option* is one of the options that command supports.
+Any number of options can be supplied for each command, and any number of
+command sections can be included in the file.  Blank lines are ignored, as are
+comments, which run from a ``'#'`` character until the end of the line.  Long
+option values can be split across multiple lines simply by indenting the
+continuation lines.
+
+You can find out the list of options supported by a particular command with the
+universal :option:`--help` option, e.g. ::
+
+   > python setup.py --help build_ext
+   [...]
+   Options for 'build_ext' command:
+     --build-lib (-b)     directory for compiled extension modules
+     --build-temp (-t)    directory for temporary files (build by-products)
+     --inplace (-i)       ignore build-lib and put compiled extensions into the
+                          source directory alongside your pure Python modules
+     --include-dirs (-I)  list of directories to search for header files
+     --define (-D)        C preprocessor macros to define
+     --undef (-U)         C preprocessor macros to undefine
+     --swig-opts          list of SWIG command-line options
+   [...]
+
+.. XXX do we want to support ``setup.py --help metadata``?
+
+Note that an option spelled :option:`--foo-bar` on the command line  is spelled
+:option:`foo_bar` in configuration files.
+
+For example, say you want your extensions to be built "in-place"---that is, you
+have an extension :mod:`pkg.ext`, and you want the compiled extension file
+(:file:`ext.so` on Unix, say) to be put in the same source directory as your
+pure Python modules :mod:`pkg.mod1` and :mod:`pkg.mod2`.  You can always use the
+:option:`--inplace` option on the command line to ensure this::
+
+   python setup.py build_ext --inplace
+
+But this requires that you always specify the :command:`build_ext` command
+explicitly, and remember to provide :option:`--inplace`. An easier way is to
+"set and forget" this option, by encoding it in :file:`setup.cfg`, the
+configuration file for this distribution::
+
+   [build_ext]
+   inplace = 1
+
+This will affect all builds of this module distribution, whether or not you
+explicitly specify :command:`build_ext`.  If you include :file:`setup.cfg` in
+your source distribution, it will also affect end-user builds---which is
+probably a bad idea for this option, since always building extensions in-place
+would break installation of the module distribution.  In certain peculiar cases,
+though, modules are built right in their installation directory, so this is
+conceivably a useful ability.  (Distributing extensions that expect to be built
+in their installation directory is almost always a bad idea, though.)
+
+Another example: certain commands take options that vary from project to
+project but not depending on the installation system, for example,
+:command:`test` needs to know where your test suite is located and what test
+runner to use; likewise, :command:`upload_docs` can find HTML documentation in
+a :file:`doc` or :file:`docs` directory, but needs an option to find files in
+:file:`docs/build/html`.  Instead of having to type out these options each
+time you want to run the command, you can put them in the project's
+:file:`setup.cfg`::
+
+   [test]
+   suite = packaging.tests
+
+   [upload_docs]
+   upload-dir = docs/build/html
+
+
+.. seealso::
+
+   :ref:`packaging-config-syntax` in "Installing Python Projects"
+      More information on the configuration files is available in the manual for
+      system administrators.
+
+
+.. rubric:: Footnotes
+
+.. [#] This ideal probably won't be achieved until auto-configuration is fully
+   supported by the Distutils.

+          setup.py
+          foo.py
+
+(In all diagrams in this section, *<root>* will refer to the distribution root
+directory.)  A minimal setup script to describe this situation would be::
+
+   from packaging.core import setup
+   setup(name='foo',
+         version='1.0',
+         py_modules=['foo'])
+
+Note that the name of the distribution is specified independently with the
+:option:`name` option, and there's no rule that says it has to be the same as
+the name of the sole module in the distribution (although that's probably a good
+convention to follow).  However, the distribution name is used to generate
+filenames, so you should stick to letters, digits, underscores, and hyphens.
+
+Since :option:`py_modules` is a list, you can of course specify multiple
+modules, e.g. if you're distributing modules :mod:`foo` and :mod:`bar`, your
+setup might look like this::
+
+   <root>/
+          setup.py
+          foo.py
+          bar.py
+
+and the setup script might be  ::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         py_modules=['foo', 'bar'])
+
+You can put module source files into another directory, but if you have enough
+modules to do that, it's probably easier to specify modules by package rather
+than listing them individually.
+
+
+.. _packaging-pure-pkg:
+
+Pure Python distribution (by package)
+=====================================
+
+If you have more than a couple of modules to distribute, especially if they are
+in multiple packages, it's probably easier to specify whole packages rather than
+individual modules.  This works even if your modules are not in a package; you
+can just tell the Distutils to process modules from the root package, and that
+works the same as any other package (except that you don't have to have an
+:file:`__init__.py` file).
+
+The setup script from the last example could also be written as  ::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         packages=[''])
+
+(The empty string stands for the root package.)
+
+If those two files are moved into a subdirectory, but remain in the root
+package, e.g.::
+
+   <root>/
+          setup.py
+          src/
+              foo.py
+              bar.py
+
+then you would still specify the root package, but you have to tell the
+Distutils where source files in the root package live::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         package_dir={'': 'src'},
+         packages=[''])
+
+More typically, though, you will want to distribute multiple modules in the same
+package (or in sub-packages).  For example, if the :mod:`foo`  and :mod:`bar`
+modules belong in package :mod:`foobar`, one way to lay out your source tree is
+
+::
+
+   <root>/
+          setup.py
+          foobar/
+                 __init__.py
+                 foo.py
+                 bar.py
+
+This is in fact the default layout expected by the Distutils, and the one that
+requires the least work to describe in your setup script::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         packages=['foobar'])
+
+If you want to put modules in directories not named for their package, then you
+need to use the :option:`package_dir` option again.  For example, if the
+:file:`src` directory holds modules in the :mod:`foobar` package::
+
+   <root>/
+          setup.py
+          src/
+              __init__.py
+              foo.py
+              bar.py
+
+an appropriate setup script would be  ::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         package_dir={'foobar': 'src'},
+         packages=['foobar'])
+
+Or, you might put modules from your main package right in the distribution
+root::
+
+   <root>/
+          setup.py
+          __init__.py
+          foo.py
+          bar.py
+
+in which case your setup script would be  ::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         package_dir={'foobar': ''},
+         packages=['foobar'])
+
+(The empty string also stands for the current directory.)
+
+If you have sub-packages, they must be explicitly listed in :option:`packages`,
+but any entries in :option:`package_dir` automatically extend to sub-packages.
+(In other words, the Distutils does *not* scan your source tree, trying to
+figure out which directories correspond to Python packages by looking for
+:file:`__init__.py` files.)  Thus, if the default layout grows a sub-package::
+
+   <root>/
+          setup.py
+          foobar/
+                 __init__.py
+                 foo.py
+                 bar.py
+                 subfoo/
+                        __init__.py
+                        blah.py
+
+then the corresponding setup script would be  ::
+
+   from packaging.core import setup
+   setup(name='foobar',
+         version='1.0',
+         packages=['foobar', 'foobar.subfoo'])
+
+(Again, the empty string in :option:`package_dir` stands for the current
+directory.)
+
+
+.. _packaging-single-ext:
+
+Single extension module
+=======================
+
+Extension modules are specified using the :option:`ext_modules` option.
+:option:`package_dir` has no effect on where extension source files are found;
+it only affects the source for pure Python modules.  The simplest  case, a
+single extension module in a single C source file, is::
+
+   <root>/
+          setup.py
+          foo.c
+
+If the :mod:`foo` extension belongs in the root package, the setup script for
+this could be  ::
+
+   from packaging.core import setup, Extension
+   setup(name='foobar',
+         version='1.0',
+         ext_modules=[Extension('foo', ['foo.c'])])
+
+If the extension actually belongs in a package, say :mod:`foopkg`, then
+
+With exactly the same source tree layout, this extension can be put in the
+:mod:`foopkg` package simply by changing the name of the extension::
+
+   from packaging.core import setup, Extension
+   setup(name='foobar',
+         version='1.0',
+         packages=['foopkg'],
+         ext_modules=[Extension('foopkg.foo', ['foo.c'])])
+
+
+Checking metadata
+=================
+
+The ``check`` command allows you to verify if your project's metadata
+meets 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 packaging.core import setup
+
+    setup(name='foobar')
+
+.. TODO configure logging StreamHandler to match this output
+
+Running the ``check`` command will display some warnings::
+
+    $ python setup.py check
+    running check
+    warning: check: missing required metadata: version, home_page
+    warning: check: missing metadata: 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 packaging.core import setup
+
+    desc = """\
+    Welcome to foobar!
+    ===============
+
+    This is the description of the ``foobar`` project.
+    """
+
+    setup(name='foobar',
+          version='1.0',
+          author=u'Tarek Ziadé',
+          author_email='tarek@ziade.org',
+          summary='Foobar utilities'
+          description=desc,
+          home_page='http://example.com')
+
+Where the long description is broken, ``check`` will be able to detect it
+by using the :mod:`docutils` parser::
+
+    $ python setup.py check --restructuredtext
+    running check
+    warning: check: Title underline too short. (line 2)
+    warning: check: Could not finish the parsing.
+
+
+.. _packaging-reading-metadata:
+
+Reading the metadata
+====================
+
+The :func:`packaging.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
+    foobar
+
+This call reads the ``name`` metadata by running the
+:func:`packaging.core.setup`  function. 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:`packaging.dist.Metadata` class and its
+:func:`read_pkg_file` method::
+
+    >>> from packaging.metadata import Metadata
+    >>> metadata = Metadata()
+    >>> 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 instantiated with a metadata file path to
+loads its values::
+
+    >>> pkg_info_path = 'distribute-0.6.8-py2.7.egg-info'
+    >>> Metadata(pkg_info_path).name
+    'distribute'

+*******************
+Extending Distutils
+*******************
+
+Distutils can be extended in various ways.  Most extensions take the form of new
+commands or replacements for existing commands.  New commands may be written to
+support new types of platform-specific packaging, for example, while
+replacements for existing commands may be made to modify details of how the
+command operates on a package.
+
+Most extensions of the packaging are made within :file:`setup.py` scripts that
+want to modify existing commands; many simply add a few file extensions that
+should be copied into packages in addition to :file:`.py` files as a
+convenience.
+
+Most packaging command implementations are subclasses of the
+:class:`packaging.cmd.Command` class.  New commands may directly inherit from
+:class:`Command`, while replacements often derive from :class:`Command`
+indirectly, directly subclassing the command they are replacing.  Commands are
+required to derive from :class:`Command`.
+
+.. .. _extend-existing:
+      Extending existing commands
+      ===========================
+
+
+.. .. _new-commands:
+      Writing new commands
+      ====================
+
+
+Integrating new commands
+========================
+
+There are different ways to integrate new command implementations into
+packaging.  The most difficult is to lobby for the inclusion of the new features
+in packaging itself, and wait for (and require) a version of Python that
+provides that support.  This is really hard for many reasons.
+
+The most common, and possibly the most reasonable for most needs, is to include
+the new implementations with your :file:`setup.py` script, and cause the
+:func:`packaging.core.setup` function use them::
+
+   from packaging.core import setup
+   from packaging.command.build_py import build_py as _build_py
+
+   class build_py(_build_py):
+       """Specialized Python source builder."""
+
+       # implement whatever needs to be different...
+
+   setup(..., cmdclass={'build_py': build_py})
+
+This approach is most valuable if the new implementations must be used to use a
+particular package, as everyone interested in the package will need to have the
+new command implementation.
+
+Beginning with Python 2.4, a third option is available, intended to allow new
+commands to be added which can support existing :file:`setup.py` scripts without
+requiring modifications to the Python installation.  This is expected to allow
+third-party extensions to provide support for additional packaging systems, but
+the commands can be used for anything packaging commands can be used for.  A new
+configuration option, :option:`command_packages` (command-line option
+:option:`--command-packages`), can be used to specify additional packages to be
+searched for modules implementing commands.  Like all packaging options, this
+can be specified on the command line or in a configuration file.  This option
+can only be set in the ``[global]`` section of a configuration file, or before
+any commands on the command line.  If set in a configuration file, it can be
+overridden from the command line; setting it to an empty string on the command
+line causes the default to be used.  This should never be set in a configuration
+file provided with a package.
+
+This new option can be used to add any number of packages to the list of
+packages searched for command implementations; multiple package names should be
+separated by commas.  When not specified, the search is only performed in the
+:mod:`packaging.command` package.  When :file:`setup.py` is run with the option
+:option:`--command-packages` :option:`distcmds,buildcmds`, however, the packages
+:mod:`packaging.command`, :mod:`distcmds`, and :mod:`buildcmds` will be searched
+in that order.  New commands are expected to be implemented in modules of the
+same name as the command by classes sharing the same name.  Given the example
+command-line option above, the command :command:`bdist_openpkg` could be
+implemented by the class :class:`distcmds.bdist_openpkg.bdist_openpkg` or
+:class:`buildcmds.bdist_openpkg.bdist_openpkg`.
+
+
+Adding new distribution types
+=============================
+
+Commands that create distributions (files in the :file:`dist/` directory) need
+to add ``(command, filename)`` pairs to ``self.distribution.dist_files`` so that
+:command:`upload` can upload it to PyPI.  The *filename* in the pair contains no
+path information, only the name of the file itself.  In dry-run mode, pairs
+should still be added to represent what would have been created.

+
+*****************************
+An Introduction to Packaging
+*****************************
+
+This document covers using Packaging to distribute your Python modules,
+concentrating on the role of developer/distributor.  If you're looking for
+information on installing Python modules you should refer to the
+:ref:`packaging-install-index` chapter.
+
+Throughout this documentation, the terms "Distutils", "the Distutils" and
+"Packaging" will be used interchangeably.
+
+.. _packaging-concepts:
+
+Concepts & Terminology
+======================
+
+Using Distutils is quite simple both for module developers and for
+users/administrators installing third-party modules.  As a developer, your
+responsibilities (apart from writing solid, well-documented and well-tested
+code, of course!) are:
+
+* writing a setup script (:file:`setup.py` by convention)
+
+* (optional) writing a setup configuration file
+
+* creating a source distribution
+
+* (optional) creating one or more "built" (binary) distributions of your
+  project
+
+All of these tasks are covered in this document.
+
+Not all module developers have access to multiple platforms, so one cannot 
+expect them to create buildt distributions for every platform.  To remedy
+this, it is hoped that intermediaries called *packagers* will arise to address
+this need.  Packagers take source distributions released by module developers,
+build them on one or more platforms and release the resulting built 
+distributions.  Thus, users on a greater range of platforms will be able to 
+install the most popular Python modules in the most natural way for their 
+platform without having to run a setup script or compile a single line of code.
+
+
+.. _packaging-simple-example:
+
+A Simple Example
+================
+
+A setup script is usually quite simple, although since it's written in Python
+there are no arbitrary limits to what you can do with it, though you should be
+careful about putting expensive operations in your setup script.
+Unlike, say, Autoconf-style configure scripts the setup script may be run
+multiple times in the course of building and installing a module
+distribution.
+
+If all you want to do is distribute a module called :mod:`foo`, contained in a
+file :file:`foo.py`, then your setup script can be as simple as::
+
+   from packaging.core import setup
+   setup(name='foo',
+         version='1.0',
+         py_modules=['foo'])
+
+Some observations:
+
+* most information that you supply to the Distutils is supplied as keyword
+  arguments to the :func:`setup` function
+
+* those keyword arguments fall into two categories: package metadata (name,
+  version number, etc.) and information about what's in the package (a list 
+  of pure Python modules in this case)
+
+* modules are specified by module name, not filename (the same will hold true
+  for packages and extensions)
+
+* it's recommended that you supply a little more metadata than we have in the 
+  example.  In particular your name, email address and a URL for the 
+  project if appropriate (see section :ref:`packaging-setup-script` for an example)
+
+To create a source distribution for this module you would create a setup
+script, :file:`setup.py`, containing the above code and run::
+
+   python setup.py sdist
+
+which will create an archive file (e.g., tarball on Unix, ZIP file on Windows)
+containing your setup script :file:`setup.py`, and your module :file:`foo.py`.
+The archive file will be named :file:`foo-1.0.tar.gz` (or :file:`.zip`), and
+will unpack into a directory :file:`foo-1.0`.
+
+If an end-user wishes to install your :mod:`foo` module all he has to do is
+download :file:`foo-1.0.tar.gz` (or :file:`.zip`), unpack it, and from the
+:file:`foo-1.0` directory run ::
+
+   python setup.py install
+
+which will copy :file:`foo.py` to the appropriate directory for
+third-party modules in their Python installation.
+
+This simple example demonstrates some fundamental concepts of Distutils.
+First, both developers and installers have the same basic user interface, i.e.
+the setup script.  The difference is which Distutils *commands* they use: the
+:command:`sdist` command is almost exclusively for module developers, while
+:command:`install` is more often used by installers (although some developers 
+will want to install their own code occasionally).
+
+If you want to make things really easy for your users, you can create more 
+than one built distributions for them.  For instance, if you are running on a
+Windows machine and want to make things easy for other Windows users, you can
+create an executable installer (the most appropriate type of built distribution
+for this platform) with the :command:`bdist_wininst` command.  For example::
+
+   python setup.py bdist_wininst
+
+will create an executable installer, :file:`foo-1.0.win32.exe`, in the current
+directory.  You can find out what distribution formats are available at any time
+by running ::
+
+   python setup.py bdist --help-formats
+
+
+.. _packaging-python-terms:
+
+General Python terminology
+==========================
+
+If you're reading this document, you probably have a good idea of what Python 
+modules, extensions and so forth are.  Nevertheless, just to be sure that 
+everyone is on the same page, here's a quick overview of Python terms:
+
+module
+   The basic unit of code reusability in Python: a block of code imported by 
+   some other code.  Three types of modules are important to us here: pure 
+   Python modules, extension modules and packages.
+
+pure Python module
+   A module written in Python and contained in a single :file:`.py` file (and
+   possibly associated :file:`.pyc` and/or :file:`.pyo` files).  Sometimes 
+   referred to as a "pure module."
+
+extension module
+   A module written in the low-level language of the Python implementation: C/C++
+   for Python, Java for Jython.  Typically contained in a single dynamically
+   loaded pre-compiled file, e.g. a shared object (:file:`.so`) file for Python
+   extensions on Unix, a DLL (given the :file:`.pyd` extension) for Python
+   extensions on Windows, or a Java class file for Jython extensions.  Note that
+   currently Distutils only handles C/C++ extensions for Python.
+
+package
+   A module that contains other modules, typically contained in a directory of 
+   the filesystem and distinguished from other directories by the presence of a 
+   file :file:`__init__.py`.
+
+root package
+   The root of the hierarchy of packages.  (This isn't really a package, 
+   since it doesn't have an :file:`__init__.py` file.  But... we have to 
+   call it something, right?)  The vast majority of the standard library is 
+   in the root package, as are many small standalone third-party modules that 
+   don't belong to a larger module collection.  Unlike regular packages, 
+   modules in the root package can be found in many directories: in fact, 
+   every directory listed in ``sys.path`` contributes modules to the root 
+   package.
+
+
+.. _packaging-term:
+
+Distutils-specific terminology
+==============================
+
+The following terms apply more specifically to the domain of distributing Python
+modules using Distutils:
+
+module distribution
+   A collection of Python modules distributed together as a single downloadable
+   resource and meant to be installed all as one.  Examples of some well-known
+   module distributions are NumPy, SciPy, PIL (the Python Imaging
+   Library) or mxBase.  (Module distributions would be called a *package*, 
+   except that term is already taken in the Python context: a single module 
+   distribution may contain zero, one, or many Python packages.)
+
+pure module distribution
+   A module distribution that contains only pure Python modules and packages.
+   Sometimes referred to as a "pure distribution."
+
+non-pure module distribution
+   A module distribution that contains at least one extension module.  Sometimes
+   referred to as a "non-pure distribution."
+
+distribution root
+   The top-level directory of your source tree (or  source distribution).  The
+   directory where :file:`setup.py` exists.  Generally  :file:`setup.py` will

+**********************************
+Registering with the Package Index
+**********************************
+
+The Python Package Index (PyPI) holds metadata describing distributions
+packaged with packaging. The packaging command :command:`register` is used to
+submit your distribution's metadata to the index. It is invoked as follows::
+
+    python setup.py register
+
+Distutils will respond with the following prompt::
+
+    running register
+    We need to know who you are, so please choose either:
+        1. use your existing login,
+        2. register as a new user,
+        3. have the server generate a new password for you (and email it to you), or
+        4. quit
+    Your selection [default 1]:
+
+Note: if your username and password are saved locally, you will not see this
+menu.
+
+If you have not registered with PyPI, then you will need to do so now. You
+should choose option 2, and enter your details as required. Soon after
+submitting your details, you will receive an email which will be used to confirm
+your registration.
+
+Once you are registered, you may choose option 1 from the menu. You will be
+prompted for your PyPI username and password, and :command:`register` will then
+submit your metadata to the index.
+
+You may submit any number of versions of your distribution to the index. If you
+alter the metadata for a particular version, you may submit it again and the
+index will be updated.
+
+PyPI holds a record for each (name, version) combination submitted. The first
+user to submit information for a given name is designated the Owner of that
+name. They may submit changes through the :command:`register` command or through
+the web interface. They may also designate other users as Owners or Maintainers.
+Maintainers may edit the package information, but not designate other Owners or
+Maintainers.
+
+By default PyPI will list all versions of a given package. To hide certain
+versions, the Hidden property should be set to yes. This must be edited through
+the web interface.
+
+
+.. _packaging-pypirc:
+
+The .pypirc file
+================
+
+The format of the :file:`.pypirc` file is as follows::
+
+    [packaging]
+    index-servers =
+        pypi
+
+    [pypi]
+    repository: <repository-url>
+    username: <username>
+    password: <password>
+
+The *packaging* section defines a *index-servers* variable that lists the
+name of all sections describing a repository.
+
+Each section describing a repository defines three variables:
+
+- *repository*, that defines the url of the PyPI server. Defaults to
+    ``http://www.python.org/pypi``.
+- *username*, which is the registered username on the PyPI server.
+- *password*, that will be used to authenticate. If omitted the user
+    will be prompt to type it when needed.
+
+If you want to define another server a new section can be created and
+listed in the *index-servers* variable::
+
+    [packaging]
+    index-servers =
+        pypi
+        other
+
+    [pypi]
+    repository: <repository-url>
+    username: <username>
+    password: <password>
+
+    [other]
+    repository: http://example.com/pypi
+    username: <username>
+    password: <password>
+
+:command:`register` can then be called with the -r option to point the
+repository to work with::
+
+    python setup.py register -r http://example.com/pypi
+
+For convenience, the name of the section that describes the repository
+may also be used::
+
+    python setup.py register -r other

+   packages_root = src
+   packages =
+       pypi2rpm
+       pypi2rpm.command
+
+   scripts =
+       pypi2rpm/pypi2rpm.py
+
+   extra_files =
+       setup.py
+       README
+
+
+.. Note::
+   The :file:`setup.cfg` configuration file is included by default.  Contrary to
+   Distutils, :file:`README` (or :file:`README.txt`) and :file:`setup.py` are
+   not included by default.
+
+
+Resources
+---------
+
+This section describes the files used by the project which must not be installed
+in the same place that python modules or libraries, they are called
+**resources**. They are for example documentation files, script files,
+databases, etc...
+
+For declaring resources, you must use this notation::
+
+   source = destination
+
+Data-files are declared in the **resources** field in the **file** section, for
+example::
+
+   [files]
+   resources =
+       source1 = destination1
+       source2 = destination2
+
+The **source** part of the declaration are relative paths of resources files
+(using unix path separator **/**). For example, if you've this source tree::
+
+   foo/
+      doc/
+         doc.man
+      scripts/
+         foo.sh
+
+Your setup.cfg will look like::
+
+   [files]
+   resources =
+       doc/doc.man = destination_doc
+       scripts/foo.sh = destination_scripts
+
+The final paths where files will be placed are composed by : **source** +
+**destination**. In the previous example, **doc/doc.man** will be placed in
+**destination_doc/doc/doc.man** and **scripts/foo.sh** will be placed in
+**destination_scripts/scripts/foo.sh**. (If you want more control on the final
+path, take a look at base_prefix_).
+
+The **destination** part of resources declaration are paths with categories.
+Indeed, it's generally a bad idea to give absolute path as it will be cross
+incompatible. So, you must use resources categories in your **destination**
+declaration. Categories will be replaced by their real path at the installation
+time. Using categories is all benefit, your declaration will be simpler, cross
+platform and it will allow packager to place resources files where they want
+without breaking your code.
+
+Categories can be specified by using this syntax::
+
+   {category}
+
+Default categories are:
+
+* config
+* appdata
+* appdata.arch
+* appdata.persistent
+* appdata.disposable
+* help
+* icon
+* scripts
+* doc
+* info
+* man
+
+A special category also exists **{distribution.name}** that will be replaced by
+the name of the distribution, but as most of the defaults categories use them,
+so it's not necessary to add **{distribution.name}** into your destination.
+
+If you use categories in your declarations, and you are encouraged to do, final
+path will be::
+
+   source + destination_expanded
+
+.. _example_final_path:
+
+For example, if you have this setup.cfg::
+
+   [metadata]
+   name = foo
+
+   [files]
+   resources =
+       doc/doc.man = {doc}
+
+And if **{doc}** is replaced by **{datadir}/doc/{distribution.name}**, final
+path will be::
+
+   {datadir}/doc/foo/doc/doc.man
+
+Where {datafir} category will be platform-dependent.
+
+
+More control on source part
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Glob syntax
+"""""""""""
+
+When you declare source file, you can use a glob-like syntax to match multiples file, for example::
+
+   scripts/* = {script}
+
+Will match all the files in the scripts directory and placed them in the script category.
+
+Glob tokens are:
+
+ * ``*``: match all files.
+ * ``?``: match any character.
+ * ``**``: match any level of tree recursion (even 0).
+ * ``{}``: will match any part separated by comma (example: ``{sh,bat}``).
+
+.. TODO Add examples
+
+Order of declaration
+""""""""""""""""""""
+
+The order of declaration is important if one file match multiple rules. The last
+rules matched by file is used, this is useful if you have this source tree::
+
+   foo/
+      doc/
+         index.rst
+         setup.rst
+         documentation.txt
+         doc.tex
+         README
+
+And you want all the files in the doc directory to be placed in {doc} category,
+but README must be placed in {help} category, instead of listing all the files
+one by one, you can declare them in this way::
+
+   [files]
+   resources =
+       doc/* = {doc}
+       doc/README = {help}
+
+Exclude
+"""""""
+
+You can exclude some files of resources declaration by giving no destination, it
+can be useful if you have a non-resources file in the same directory of
+resources files::
+
+   foo/
+      doc/
+         RELEASES
+         doc.tex
+         documentation.txt
+         docu.rst
+
+Your **files** section will be::
+
+   [files]
+   resources =
+       doc/* = {doc}
+       doc/RELEASES =
+
+More control on destination part
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. _base_prefix:
+
+Defining a base prefix
+""""""""""""""""""""""
+
+When you define your resources, you can have more control of how the final path
+is compute.
+
+By default, the final path is::
+
+   destination + source
+
+This can generate long paths, for example (example_final_path_)::
+
+   {datadir}/doc/foo/doc/doc.man
+
+When you declare your source, you can use whitespace to split the source in
+**prefix** **suffix**.  So, for example, if you have this source::
+
+   docs/ doc.man
+
+The **prefix** is "docs/" and the **suffix** is "doc.html".
+
+.. note::
+
+   Separator can be placed after a path separator or replace it. So these two
+   sources are equivalent::
+
+      docs/ doc.man
+      docs doc.man
+
+.. note::
+
+   Glob syntax is working the same way with standard source and splitted source.
+   So these rules::
+
+      docs/*
+      docs/ *
+      docs *
+
+   Will match all the files in the docs directory.
+
+When you use splitted source, the final path is compute in this way::
+
+   destination + prefix
+
+So for example, if you have this setup.cfg::
+
+   [metadata]
+   name = foo
+
+   [files]
+   resources =
+       doc/ doc.man = {doc}
+
+And if **{doc}** is replaced by **{datadir}/doc/{distribution.name}**, final
+path will be::
+
+   {datadir}/doc/foo/doc.man
+
+
+Overwriting paths for categories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This part is intended for system administrators or downstream OS packagers.
+
+The real paths of categories are registered in the *sysconfig.cfg* file
+installed in your python installation. This file uses an ini format too.
+The content of the file is organized into several sections:
+
+* globals: Standard categories's paths.
+* posix_prefix: Standard paths for categories and installation paths for posix
+  system.
+* other ones XXX
+
+Standard categories paths are platform independent, they generally refers to
+other categories, which are platform dependent. :mod:`sysconfig` will choose
+these category from sections matching os.name. For example::
+
+   doc = {datadir}/doc/{distribution.name}
+
+It refers to datadir category, which can be different between platforms. In
+posix system, it may be::
+
+   datadir = /usr/share
+
+So the final path will be::
+
+   doc = /usr/share/doc/{distribution.name}
+
+The platform-dependent categories are:
+
+* confdir
+* datadir
+* libdir
+* base
+
+
+Defining extra categories
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. TODO
+
+
+Examples
+^^^^^^^^
+
+These examples are incremental but work unitarily.

+
+************************
+Writing the Setup Script
+************************
+
+The setup script is the center of all activity in building, distributing, and
+installing modules using Distutils.  The main purpose of the setup script is
+to describe your module distribution to Distutils, so that the various
+commands that operate on your modules do the right thing.  As we saw in section
+:ref:`packaging-simple-example`, the setup script consists mainly of a
+call to :func:`setup` where the most information is supplied as 
+keyword arguments to :func:`setup`.
+
+Here's a slightly more involved example, which we'll follow for the next couple
+of sections: a setup script that could be used for Packaging itself::
+
+    #!/usr/bin/env python
+
+    from packaging.core import setup, find_packages
+
+    setup(name='Packaging',
+          version='1.0',
+          summary='Python Distribution Utilities',
+          keywords=['packaging', 'packaging'],
+          author=u'Tarek Ziadé',
+          author_email='tarek@ziade.org',
+          home_page='http://bitbucket.org/tarek/packaging/wiki/Home',
+          license='PSF',
+          packages=find_packages())
+
+
+There are only two differences between this and the trivial one-file
+distribution presented in section :ref:`packaging-simple-example`: more
+metadata and the specification of pure Python modules by package rather than
+by module.  This is important since Ristutils consist of a couple of dozen
+modules split into (so far) two packages; an explicit list of every module
+would be tedious to generate and difficult to maintain.  For more information
+on the additional metadata, see section :ref:`packaging-metadata`.
+
+Note that any pathnames (files or directories) supplied in the setup script
+should be written using the Unix convention, i.e. slash-separated.  The
+Distutils will take care of converting this platform-neutral representation into
+whatever is appropriate on your current platform before actually using the
+pathname.  This makes your setup script portable across operating systems, which
+of course is one of the major goals of the Distutils.  In this spirit, all
+pathnames in this document are slash-separated.
+
+This, of course, only applies to pathnames given to Distutils functions.  If
+you, for example, use standard Python functions such as :func:`glob.glob` or
+:func:`os.listdir` to specify files, you should be careful to write portable
+code instead of hardcoding path separators::
+
+    glob.glob(os.path.join('mydir', 'subdir', '*.html'))
+    os.listdir(os.path.join('mydir', 'subdir'))
+
+
+.. _packaging-listing-packages:
+
+Listing whole packages
+======================
+
+The :option:`packages` option tells the Distutils to process (build, distribute,
+install, etc.) all pure Python modules found in each package mentioned in the
+:option:`packages` list.  In order to do this, of course, there has to be a
+correspondence between package names and directories in the filesystem.  The
+default correspondence is the most obvious one, i.e. package :mod:`packaging` is
+found in the directory :file:`packaging` relative to the distribution root.
+Thus, when you say ``packages = ['foo']`` in your setup script, you are
+promising that the Distutils will find a file :file:`foo/__init__.py` (which
+might be spelled differently on your system, but you get the idea) relative to
+the directory where your setup script lives.  If you break this promise, the
+Distutils will issue a warning but still process the broken package anyways.
+
+If you use a different convention to lay out your source directory, that's no
+problem: you just have to supply the :option:`package_dir` option to tell the
+Distutils about your convention.  For example, say you keep all Python source
+under :file:`lib`, so that modules in the "root package" (i.e., not in any
+package at all) are in :file:`lib`, modules in the :mod:`foo` package are in
+:file:`lib/foo`, and so forth.  Then you would put ::
+
+    package_dir = {'': 'lib'}
+
+in your setup script.  The keys to this dictionary are package names, and an
+empty package name stands for the root package.  The values are directory names
+relative to your distribution root.  In this case, when you say ``packages =
+['foo']``, you are promising that the file :file:`lib/foo/__init__.py` exists.
+
+Another possible convention is to put the :mod:`foo` package right in
+:file:`lib`, the :mod:`foo.bar` package in :file:`lib/bar`, etc.  This would be
+written in the setup script as ::
+
+    package_dir = {'foo': 'lib'}
+
+A ``package: dir`` entry in the :option:`package_dir` dictionary implicitly
+applies to all packages below *package*, so the :mod:`foo.bar` case is
+automatically handled here.  In this example, having ``packages = ['foo',
+'foo.bar']`` tells the Distutils to look for :file:`lib/__init__.py` and
+:file:`lib/bar/__init__.py`.  (Keep in mind that although :option:`package_dir`
+applies recursively, you must explicitly list all packages in
+:option:`packages`: the Distutils will *not* recursively scan your source tree
+looking for any directory with an :file:`__init__.py` file.)
+
+
+.. _packaging-listing-modules:
+
+Listing individual modules
+==========================
+
+For a small module distribution, you might prefer to list all modules rather
+than listing packages---especially the case of a single module that goes in the
+"root package" (i.e., no package at all).  This simplest case was shown in
+section :ref:`packaging-simple-example`; here is a slightly more involved
+example::
+
+    py_modules = ['mod1', 'pkg.mod2']
+
+This describes two modules, one of them in the "root" package, the other in the
+:mod:`pkg` package.  Again, the default package/directory layout implies that
+these two modules can be found in :file:`mod1.py` and :file:`pkg/mod2.py`, and
+that :file:`pkg/__init__.py` exists as well. And again, you can override the
+package/directory correspondence using the :option:`package_dir` option.
+
+
+.. _packaging-describing-extensions:
+
+Describing extension modules
+============================
+
+Just as writing Python extension modules is a bit more complicated than writing
+pure Python modules, describing them to the Distutils is a bit more complicated.
+Unlike pure modules, it's not enough just to list modules or packages and expect
+the Distutils to go out and find the right files; you have to specify the
+extension name, source file(s), and any compile/link requirements (include
+directories, libraries to link with, etc.).
+
+.. XXX read over this section
+
+All of this is done through another keyword argument to :func:`setup`, the
+:option:`ext_modules` option.  :option:`ext_modules` is just a list of
+:class:`Extension` instances, each of which describes a single extension module.
+Suppose your distribution includes a single extension, called :mod:`foo` and
+implemented by :file:`foo.c`.  If no additional instructions to the
+compiler/linker are needed, describing this extension is quite simple::
+
+    Extension('foo', ['foo.c'])
+
+The :class:`Extension` class can be imported from :mod:`packaging.core` along
+with :func:`setup`.  Thus, the setup script for a module distribution that
+contains only this one extension and nothing else might be::
+
+    from packaging.core import setup, Extension
+    setup(name='foo',
+          version='1.0',
+          ext_modules=[Extension('foo', ['foo.c'])])
+
+The :class:`Extension` class (actually, the underlying extension-building
+machinery implemented by the :command:`build_ext` command) supports a great deal
+of flexibility in describing Python extensions, which is explained in the
+following sections.
+
+
+Extension names and packages
+----------------------------
+
+The first argument to the :class:`Extension` constructor is always the name of
+the extension, including any package names.  For example, ::
+
+    Extension('foo', ['src/foo1.c', 'src/foo2.c'])
+
+describes an extension that lives in the root package, while ::
+
+    Extension('pkg.foo', ['src/foo1.c', 'src/foo2.c'])
+
+describes the same extension in the :mod:`pkg` package.  The source files and
+resulting object code are identical in both cases; the only difference is where
+in the filesystem (and therefore where in Python's namespace hierarchy) the
+resulting extension lives.
+
+If you have a number of extensions all in the same package (or all under the
+same base package), use the :option:`ext_package` keyword argument to
+:func:`setup`.  For example, ::
+
+    setup(...,
+          ext_package='pkg',
+          ext_modules=[Extension('foo', ['foo.c']),
+                       Extension('subpkg.bar', ['bar.c'])])
+
+will compile :file:`foo.c` to the extension :mod:`pkg.foo`, and :file:`bar.c` to
+:mod:`pkg.subpkg.bar`.
+
+
+Extension source files
+----------------------
+
+The second argument to the :class:`Extension` constructor is a list of source
+files.  Since the Distutils currently only support C, C++, and Objective-C
+extensions, these are normally C/C++/Objective-C source files.  (Be sure to use
+appropriate extensions to distinguish C++\ source files: :file:`.cc` and
+:file:`.cpp` seem to be recognized by both Unix and Windows compilers.)
+
+However, you can also include SWIG interface (:file:`.i`) files in the list; the
+:command:`build_ext` command knows how to deal with SWIG extensions: it will run
+SWIG on the interface file and compile the resulting C/C++ file into your
+extension.
+
+.. XXX SWIG support is rough around the edges and largely untested!
+
+This warning notwithstanding, options to SWIG can be currently passed like
+this::
+
+    setup(...,
+          ext_modules=[Extension('_foo', ['foo.i'],
+                                 swig_opts=['-modern', '-I../include'])],
+          py_modules=['foo'])
+
+Or on the command line like this::
+
+    > python setup.py build_ext --swig-opts="-modern -I../include"
+
+On some platforms, you can include non-source files that are processed by the
+compiler and included in your extension.  Currently, this just means Windows
+message text (:file:`.mc`) files and resource definition (:file:`.rc`) files for
+Visual C++. These will be compiled to binary resource (:file:`.res`) files and
+linked into the executable.
+
+
+Preprocessor options
+--------------------
+
+Three optional arguments to :class:`Extension` will help if you need to specify
+include directories to search or preprocessor macros to define/undefine:
+``include_dirs``, ``define_macros``, and ``undef_macros``.
+
+For example, if your extension requires header files in the :file:`include`
+directory under your distribution root, use the ``include_dirs`` option::
+
+    Extension('foo', ['foo.c'], include_dirs=['include'])
+
+You can specify absolute directories there; if you know that your extension will
+only be built on Unix systems with X11R6 installed to :file:`/usr`, you can get
+away with ::
+
+    Extension('foo', ['foo.c'], include_dirs=['/usr/include/X11'])
+
+You should avoid this sort of non-portable usage if you plan to distribute your
+code: it's probably better to write C code like  ::
+
+    #include <X11/Xlib.h>
+
+If you need to include header files from some other Python extension, you can
+take advantage of the fact that header files are installed in a consistent way
+by the Distutils :command:`install_header` command.  For example, the Numerical
+Python header files are installed (on a standard Unix installation) to
+:file:`/usr/local/include/python1.5/Numerical`. (The exact location will differ
+according to your platform and Python installation.)  Since the Python include
+directory---\ :file:`/usr/local/include/python1.5` in this case---is always
+included in the search path when building Python extensions, the best approach
+is to write C code like  ::
+
+    #include <Numerical/arrayobject.h>
+
+.. TODO check if it's d2.sysconfig or the new sysconfig module now
+
+If you must put the :file:`Numerical` include directory right into your header
+search path, though, you can find that directory using the Distutils
+:mod:`packaging.sysconfig` module::
+
+    from packaging.sysconfig import get_python_inc
+    incdir = os.path.join(get_python_inc(plat_specific=1), 'Numerical')
+    setup(...,
+          Extension(..., include_dirs=[incdir]))
+
+Even though this is quite portable---it will work on any Python installation,
+regardless of platform---it's probably easier to just write your C code in the
+sensible way.
+
+You can define and undefine preprocessor macros with the ``define_macros`` and
+``undef_macros`` options. ``define_macros`` takes a list of ``(name, value)``
+tuples, where ``name`` is the name of the macro to define (a string) and
+``value`` is its value: either a string or ``None``.  (Defining a macro ``FOO``
+to ``None`` is the equivalent of a bare ``#define FOO`` in your C source: with
+most compilers, this sets ``FOO`` to the string ``1``.)  ``undef_macros`` is
+just a list of macros to undefine.
+
+For example::
+
+    Extension(...,
+              define_macros=[('NDEBUG', '1'),
+                             ('HAVE_STRFTIME', None)],
+              undef_macros=['HAVE_FOO', 'HAVE_BAR'])
+
+is the equivalent of having this at the top of every C source file::
+
+    #define NDEBUG 1
+    #define HAVE_STRFTIME
+    #undef HAVE_FOO
+    #undef HAVE_BAR
+
+
+Library options
+---------------
+
+You can also specify the libraries to link against when building your extension,
+and the directories to search for those libraries.  The ``libraries`` option is
+a list of libraries to link against, ``library_dirs`` is a list of directories
+to search for libraries at  link-time, and ``runtime_library_dirs`` is a list of
+directories to  search for shared (dynamically loaded) libraries at run-time.
+
+For example, if you need to link against libraries known to be in the standard
+library search path on target systems ::
+
+    Extension(...,
+              libraries=['gdbm', 'readline'])
+
+If you need to link with libraries in a non-standard location, you'll have to
+include the location in ``library_dirs``::
+
+    Extension(...,
+              library_dirs=['/usr/X11R6/lib'],
+              libraries=['X11', 'Xt'])
+
+(Again, this sort of non-portable construct should be avoided if you intend to
+distribute your code.)
+
+.. XXX Should mention clib libraries here or somewhere else!
+
+
+Other options
+-------------
+
+There are still some other options which can be used to handle special cases.
+
+The :option:`optional` option is a boolean; if it is true,
+a build failure in the extension will not abort the build process, but
+instead simply not install the failing extension.
+
+The :option:`extra_objects` option is a list of object files to be passed to the
+linker. These files must not have extensions, as the default extension for the
+compiler is used.
+
+:option:`extra_compile_args` and :option:`extra_link_args` can be used to
+specify additional command-line options for the respective compiler and linker
+command lines.
+
+:option:`export_symbols` is only useful on Windows.  It can contain a list of
+symbols (functions or variables) to be exported. This option is not needed when
+building compiled extensions: Distutils  will automatically add ``initmodule``
+to the list of exported symbols.
+
+The :option:`depends` option is a list of files that the extension depends on
+(for example header files). The build command will call the compiler on the
+sources to rebuild extension if any on this files has been modified since the
+previous build.
+
+Relationships between Distributions and Packages
+================================================
+
+.. FIXME rewrite to update to PEP 345 (but without dist/release confusion)
+
+A distribution may relate to packages in three specific ways:
+
+#. It can require packages or modules.
+
+#. It can provide packages or modules.
+
+#. It can obsolete packages or modules.
+
+These relationships can be specified using keyword arguments to the
+:func:`packaging.core.setup` function.
+
+Dependencies on other Python modules and packages can be specified by supplying
+the *requires* keyword argument to :func:`setup`. The value must be a list of
+strings.  Each string specifies a package that is required, and optionally what
+versions are sufficient.
+
+To specify that any version of a module or package is required, the string
+should consist entirely of the module or package name. Examples include
+``'mymodule'`` and ``'xml.parsers.expat'``.
+
+If specific versions are required, a sequence of qualifiers can be supplied in
+parentheses.  Each qualifier may consist of a comparison operator and a version
+number.  The accepted comparison operators are::
+
+    <    >    ==
+    <=   >=   !=
+
+These can be combined by using multiple qualifiers separated by commas (and
+optional whitespace).  In this case, all of the qualifiers must be matched; a
+logical AND is used to combine the evaluations.
+
+Let's look at a bunch of examples:
+
++-------------------------+----------------------------------------------+
+| Requires Expression     | Explanation                                  |
++=========================+==============================================+
+| ``==1.0``               | Only version ``1.0`` is compatible           |
++-------------------------+----------------------------------------------+
+| ``>1.0, !=1.5.1, <2.0`` | Any version after ``1.0`` and before ``2.0`` |
+|                         | is compatible, except ``1.5.1``              |
++-------------------------+----------------------------------------------+
+
+Now that we can specify dependencies, we also need to be able to specify what we
+provide that other distributions can require.  This is done using the *provides*
+keyword argument to :func:`setup`. The value for this keyword is a list of
+strings, each of which names a Python module or package, and optionally
+identifies the version.  If the version is not specified, it is assumed to match
+that of the distribution.
+
+Some examples:
+
++---------------------+----------------------------------------------+
+| Provides Expression | Explanation                                  |
++=====================+==============================================+
+| ``mypkg``           | Provide ``mypkg``, using the distribution    |
+|                     | version                                      |
++---------------------+----------------------------------------------+
+| ``mypkg (1.1)``     | Provide ``mypkg`` version 1.1, regardless of |
+|                     | the distribution version                     |
++---------------------+----------------------------------------------+
+
+A package can declare that it obsoletes other packages using the *obsoletes*
+keyword argument.  The value for this is similar to that of the *requires*
+keyword: a list of strings giving module or package specifiers.  Each specifier
+consists of a module or package name optionally followed by one or more version
+qualifiers.  Version qualifiers are given in parentheses after the module or
+package name.
+
+The versions identified by the qualifiers are those that are obsoleted by the
+distribution being described.  If no qualifiers are given, all versions of the
+named module or package are understood to be obsoleted.
+
+.. _packaging-installing-scripts:
+
+Installing Scripts
+==================
+
+So far we have been dealing with pure and non-pure Python modules, which are
+usually not run by themselves but imported by scripts.
+
+Scripts are files containing Python source code, intended to be started from the
+command line.  Scripts don't require Distutils to do anything very complicated.
+The only clever feature is that if the first line of the script starts with
+``#!`` and contains the word "python", the Distutils will adjust the first line
+to refer to the current interpreter location. By default, it is replaced with
+the current interpreter location.  The :option:`--executable` (or :option:`-e`)
+option will allow the interpreter path to be explicitly overridden.
+
+The :option:`scripts` option simply is a list of files to be handled in this
+way.  From the PyXML setup script::
+
+    setup(...,
+          scripts=['scripts/xmlproc_parse', 'scripts/xmlproc_val'])
+
+All the scripts will also be added to the ``MANIFEST`` file if no template is
+provided. See :ref:`packaging-manifest`.
+
+.. _packaging-installing-package-data:
+
+Installing Package Data
+=======================
+
+Often, additional files need to be installed into a package.  These files are
+often data that's closely related to the package's implementation, or text files
+containing documentation that might be of interest to programmers using the
+package.  These files are called :dfn:`package data`.
+
+Package data can be added to packages using the ``package_data`` keyword
+argument to the :func:`setup` function.  The value must be a mapping from
+package name to a list of relative path names that should be copied into the
+package.  The paths are interpreted as relative to the directory containing the
+package (information from the ``package_dir`` mapping is used if appropriate);
+that is, the files are expected to be part of the package in the source
+directories. They may contain glob patterns as well.
+
+The path names may contain directory portions; any necessary directories will be
+created in the installation.
+
+For example, if a package should contain a subdirectory with several data files,
+the files can be arranged like this in the source tree::
+
+    setup.py
+    src/
+        mypkg/
+              __init__.py
+              module.py
+              data/
+                   tables.dat
+                   spoons.dat
+                   forks.dat
+
+The corresponding call to :func:`setup` might be::
+
+    setup(...,
+          packages=['mypkg'],
+          package_dir={'mypkg': 'src/mypkg'},
+          package_data={'mypkg': ['data/*.dat']})
+
+
+All the files that match ``package_data`` will be added to the ``MANIFEST``
+file if no template is provided. See :ref:`packaging-manifest`.
+
+
+.. _packaging-additional-files:
+
+Installing Additional Files
+===========================
+
+The :option:`data_files` option can be used to specify additional files needed
+by the module distribution: configuration files, message catalogs, data files,
+anything which doesn't fit in the previous categories.
+
+:option:`data_files` specifies a sequence of (*directory*, *files*) pairs in the
+following way::
+
+    setup(...,
+          data_files=[('bitmaps', ['bm/b1.gif', 'bm/b2.gif']),
+                      ('config', ['cfg/data.cfg']),
+                      ('/etc/init.d', ['init-script'])])
+
+Note that you can specify the directory names where the data files will be
+installed, but you cannot rename the data files themselves.
+
+Each (*directory*, *files*) pair in the sequence specifies the installation
+directory and the files to install there.  If *directory* is a relative path, it
+is interpreted relative to the installation prefix (Python's ``sys.prefix`` for
+pure-Python packages, ``sys.exec_prefix`` for packages that contain extension
+modules).  Each file name in *files* is interpreted relative to the
+:file:`setup.py` script at the top of the package source distribution.  No
+directory information from *files* is used to determine the final location of
+the installed file; only the name of the file is used.
+
+You can specify the :option:`data_files` options as a simple sequence of files
+without specifying a target directory, but this is not recommended, and the
+:command:`install_dist` command will print a warning in this case. To install data
+files directly in the target directory, an empty string should be given as the
+directory.
+
+All the files that match ``data_files`` will be added to the ``MANIFEST`` file
+if no template is provided. See :ref:`packaging-manifest`.
+
+
+
+.. _packaging-metadata:
+
+Metadata reference
+==================
+
+The setup script may include additional metadata beyond the name and version.
+This table describes required and additional information:
+
+.. TODO synchronize with setupcfg; link to it (but don't remove it, it's a
+   useful summary)
+

+Encoding the version information is an art in itself. Python projects generally

+for initial, experimental releases of software. It is incremented for releases
+that represent major milestones in a project. The minor number is incremented
+when important new features are added to the project. The patch number
+increments when bug-fix releases are made. Additional trailing version
+information is sometimes used to indicate sub-releases.  These are
+"a1,a2,...,aN" (for alpha releases, where functionality and API may change),
+"b1,b2,...,bN" (for beta releases, which only fix bugs) and "pr1,pr2,...,prN"
+(for final pre-release release testing). Some examples:

+              'Topic :: Software Development :: Bug Tracking',
+              ])
+
+
+Debugging the setup script
+==========================
+
+Sometimes things go wrong, and the setup script doesn't do what the developer
+wants.
+
+Distutils catches any exceptions when running the setup script, and print a
+simple error message before the script is terminated.  The motivation for this
+behaviour is to not confuse administrators who don't know much about Python and
+are trying to install a project.  If they get a big long traceback from deep
+inside the guts of Distutils, they may think the project or the Python
+installation is broken because they don't read all the way down to the bottom
+and see that it's a permission problem.
+
+.. FIXME DISTUTILS_DEBUG is dead, document logging/warnings here
+
+On the other hand, this doesn't help the developer to find the cause of the
+failure. For this purpose, the DISTUTILS_DEBUG environment variable can be set
+to anything except an empty string, and Packaging will now print detailed
+information about what it is doing, and prints the full traceback in case an
+exception occurs.

+
+******************************
+Creating a Source Distribution
+******************************
+
+As shown in section :ref:`packaging-simple-example`, you use the :command:`sdist` command
+to create a source distribution.  In the simplest case, ::
+
+   python setup.py sdist
+
+(assuming you haven't specified any :command:`sdist` options in the setup script
+or config file), :command:`sdist` creates the archive of the default format for
+the current platform.  The default format is a gzip'ed tar file
+(:file:`.tar.gz`) on Unix, and ZIP file on Windows.
+
+You can specify as many formats as you like using the :option:`--formats`
+option, for example::
+
+   python setup.py sdist --formats=gztar,zip
+
+to create a gzipped tarball and a zip file.  The available formats are:
+
++-----------+-------------------------+---------+
+| Format    | Description             | Notes   |
++===========+=========================+=========+
+| ``zip``   | zip file (:file:`.zip`) | (1),(3) |
++-----------+-------------------------+---------+
+| ``gztar`` | gzip'ed tar file        | \(2)    |
+|           | (:file:`.tar.gz`)       |         |
++-----------+-------------------------+---------+
+| ``bztar`` | bzip2'ed tar file       |         |
+|           | (:file:`.tar.bz2`)      |         |
++-----------+-------------------------+---------+
+| ``ztar``  | compressed tar file     | \(4)    |
+|           | (:file:`.tar.Z`)        |         |
++-----------+-------------------------+---------+
+| ``tar``   | tar file (:file:`.tar`) |         |
++-----------+-------------------------+---------+
+
+Notes:
+
+(1)
+   default on Windows
+
+(2)
+   default on Unix
+
+(3)
+   requires either external :program:`zip` utility or :mod:`zipfile` module (part
+   of the standard Python library since Python 1.6)
+
+(4)
+   requires the :program:`compress` program. Notice that this format is now
+   pending for deprecation and will be removed in the future versions of Python.
+
+When using any ``tar`` format (``gztar``, ``bztar``, ``ztar`` or
+``tar``) under Unix, you can specify the ``owner`` and ``group`` names
+that will be set for each member of the archive.
+
+For example, if you want all files of the archive to be owned by root::
+
+    python setup.py sdist --owner=root --group=root
+
+
+.. _packaging-manifest:
+
+Specifying the files to distribute
+==================================
+
+If you don't supply an explicit list of files (or instructions on how to
+generate one), the :command:`sdist` command puts a minimal default set into the
+source distribution:
+
+* all Python source files implied by the :option:`py_modules` and
+  :option:`packages` options
+
+* all C source files mentioned in the :option:`ext_modules` or
+  :option:`libraries` options
+
+* scripts identified by the :option:`scripts` option
+  See :ref:`packaging-installing-scripts`.
+
+* anything that looks like a test script: :file:`test/test\*.py` (currently, the
+  Packaging don't do anything with test scripts except include them in source
+  distributions, but in the future there will be a standard for testing Python
+  module distributions)
+
+* the configuration file :file:`setup.cfg`
+
+* all files that matches the ``package_data`` metadata.
+  See :ref:`packaging-installing-package-data`.
+
+* all files that matches the ``data_files`` metadata.
+  See :ref:`packaging-additional-files`.
+
+Contrary to Distutils, :file:`README` (or :file:`README.txt`) and
+:file:`setup.py` are not included by default.
+
+Sometimes this is enough, but usually you will want to specify additional files
+to distribute.  The typical way to do this is to write a *manifest template*,
+called :file:`MANIFEST.in` by default.  The manifest template is just a list of
+instructions for how to generate your manifest file, :file:`MANIFEST`, which is
+the exact list of files to include in your source distribution.  The
+:command:`sdist` command processes this template and generates a manifest based
+on its instructions and what it finds in the filesystem.
+
+If you prefer to roll your own manifest file, the format is simple: one filename
+per line, regular files (or symlinks to them) only.  If you do supply your own
+:file:`MANIFEST`, you must specify everything: the default set of files
+described above does not apply in this case.
+
+:file:`MANIFEST` files start with a comment indicating they are generated.
+Files without this comment are not overwritten or removed.
+
+See :ref:`packaging-manifest-template` section for a syntax reference.
+
+
+.. _packaging-manifest-options:
+
+Manifest-related options
+========================
+
+The normal course of operations for the :command:`sdist` command is as follows:
+
+* if the manifest file, :file:`MANIFEST` doesn't exist, read :file:`MANIFEST.in`
+  and create the manifest
+
+* if neither :file:`MANIFEST` nor :file:`MANIFEST.in` exist, create a manifest
+  with just the default file set
+
+* if either :file:`MANIFEST.in` or the setup script (:file:`setup.py`) are more
+  recent than :file:`MANIFEST`, recreate :file:`MANIFEST` by reading
+  :file:`MANIFEST.in`
+
+* use the list of files now in :file:`MANIFEST` (either just generated or read
+  in) to create the source distribution archive(s)
+
+There are a couple of options that modify this behaviour.  First, use the
+:option:`--no-defaults` and :option:`--no-prune` to disable the standard
+"include" and "exclude" sets.
+
+Second, you might just want to (re)generate the manifest, but not create a
+source distribution::
+
+   python setup.py sdist --manifest-only
+
+:option:`-o` is a shortcut for :option:`--manifest-only`.
+
+
+.. _packaging-manifest-template:
+
+The MANIFEST.in template
+========================
+
+A :file:`MANIFEST.in` file can be added in a project to define the list of
+files to include in the distribution built by the :command:`sdist` command.
+
+When :command:`sdist` is run, it will look for the :file:`MANIFEST.in` file
+and interpret it to generate the :file:`MANIFEST` file that contains the
+list of files that will be included in the package.
+
+This mechanism can be used when the default list of files is not enough.
+(See :ref:`packaging-manifest`).
+
+Principle
+---------
+
+The manifest template has one command per line, where each command specifies a
+set of files to include or exclude from the source distribution.  For an
+example, let's look at the Packaging' own manifest template::
+
+   include *.txt
+   recursive-include examples *.txt *.py
+   prune examples/sample?/build
+
+The meanings should be fairly clear: include all files in the distribution root
+matching :file:`\*.txt`, all files anywhere under the :file:`examples` directory
+matching :file:`\*.txt` or :file:`\*.py`, and exclude all directories matching
+:file:`examples/sample?/build`.  All of this is done *after* the standard
+include set, so you can exclude files from the standard set with explicit
+instructions in the manifest template.  (Or, you can use the
+:option:`--no-defaults` option to disable the standard set entirely.)
+
+The order of commands in the manifest template matters: initially, we have the
+list of default files as described above, and each command in the template adds
+to or removes from that list of files.  Once we have fully processed the
+manifest template, we remove files that should not be included in the source
+distribution:
+
+* all files in the Packaging "build" tree (default :file:`build/`)
+
+* all files in directories named :file:`RCS`, :file:`CVS`, :file:`.svn`,
+  :file:`.hg`, :file:`.git`, :file:`.bzr` or :file:`_darcs`
+
+Now we have our complete list of files, which is written to the manifest for
+future reference, and then used to build the source distribution archive(s).
+
+You can disable the default set of included files with the
+:option:`--no-defaults` option, and you can disable the standard exclude set
+with :option:`--no-prune`.
+
+Following the Packaging' own manifest template, let's trace how the
+:command:`sdist` command builds the list of files to include in the Packaging
+source distribution:
+
+#. include all Python source files in the :file:`packaging` and
+   :file:`packaging/command` subdirectories (because packages corresponding to
+   those two directories were mentioned in the :option:`packages` option in the
+   setup script---see section :ref:`packaging-setup-script`)
+
+#. include :file:`README.txt`, :file:`setup.py`, and :file:`setup.cfg` (standard
+   files)
+
+#. include :file:`test/test\*.py` (standard files)
+
+#. include :file:`\*.txt` in the distribution root (this will find
+   :file:`README.txt` a second time, but such redundancies are weeded out later)
+
+#. include anything matching :file:`\*.txt` or :file:`\*.py` in the sub-tree
+   under :file:`examples`,
+
+#. exclude all files in the sub-trees starting at directories matching
+   :file:`examples/sample?/build`\ ---this may exclude files included by the
+   previous two steps, so it's important that the ``prune`` command in the manifest
+   template comes after the ``recursive-include`` command
+
+#. exclude the entire :file:`build` tree, and any :file:`RCS`, :file:`CVS`,
+   :file:`.svn`, :file:`.hg`, :file:`.git`, :file:`.bzr` and :file:`_darcs`
+   directories
+
+Just like in the setup script, file and directory names in the manifest template
+should always be slash-separated; the Packaging will take care of converting
+them to the standard representation on your platform. That way, the manifest
+template is portable across operating systems.
+
+Commands
+--------
+
+The manifest template commands are:
+
++-------------------------------------------+-----------------------------------------------+
+| Command                                   | Description                                   |

++-------------------------------------------+-----------------------------------------------+
+| :command:`exclude pat1 pat2 ...`          | exclude all files matching any of the listed  |
+|                                           | patterns                                      |
++-------------------------------------------+-----------------------------------------------+
+| :command:`recursive-include dir pat1 pat2 | include all files under *dir* matching any of |
+| ...`                                      | the listed patterns                           |
++-------------------------------------------+-----------------------------------------------+
+| :command:`recursive-exclude dir pat1 pat2 | exclude all files under *dir* matching any of |
+| ...`                                      | the listed patterns                           |
++-------------------------------------------+-----------------------------------------------+
+| :command:`global-include pat1 pat2 ...`   | include all files anywhere in the source tree |
+|                                           | matching --- & any of the listed patterns     |
++-------------------------------------------+-----------------------------------------------+
+| :command:`global-exclude pat1 pat2 ...`   | exclude all files anywhere in the source tree |
+|                                           | matching --- & any of the listed patterns     |
++-------------------------------------------+-----------------------------------------------+
+| :command:`prune dir`                      | exclude all files under *dir*                 |
++-------------------------------------------+-----------------------------------------------+
+| :command:`graft dir`                      | include all files under *dir*                 |
++-------------------------------------------+-----------------------------------------------+
+
+The patterns here are Unix-style "glob" patterns: ``*`` matches any sequence of
+regular filename characters, ``?`` matches any single regular filename
+character, and ``[range]`` matches any of the characters in *range* (e.g.,
+``a-z``, ``a-zA-Z``, ``a-f0-9_.``).  The definition of "regular filename
+character" is platform-specific: on Unix it is anything except slash; on Windows
+anything except backslash or colon.

+==================
+Packaging tutorial
+==================
+
+Welcome to the Packaging tutorial! We will learn how to use Packaging
+to package your project.
+
+.. TODO merge with introduction.rst
+
+
+Getting started
+---------------
+
+Packaging works with the *setup.cfg* file. It contains all the metadata for
+your project, as defined in PEP 345, but also declare what your project
+contains.
+
+Let's say you have a project called *CLVault* containing one package called
+*clvault*, and a few scripts inside. You can use the *pysetup* script to create
+a *setup.cfg* file for the project. The script will ask you a few questions::
+
+   $ mkdir CLVault
+   $ cd CLVault
+   $ pysetup create
+   Project name [CLVault]:
+   Current version number: 0.1
+   Package description:
+   >Command-line utility to store and retrieve passwords
+   Author name: Tarek Ziade
+   Author e-mail address: tarek@ziade.org
+   Project Home Page: http://bitbucket.org/tarek/clvault
+   Do you want to add a package ? (y/n): y
+   Package name: clvault
+   Do you want to add a package ? (y/n): n
+   Do you want to set Trove classifiers? (y/n): y
+   Please select the project status:
+
+   1 - Planning
+   2 - Pre-Alpha
+   3 - Alpha
+   4 - Beta
+   5 - Production/Stable
+   6 - Mature
+   7 - Inactive
+
+   Status: 3
+   What license do you use: GPL
+   Matching licenses:
+
+   1) License :: OSI Approved :: GNU General Public License (GPL)
+   2) License :: OSI Approved :: GNU Library or Lesser General Public License (LGPL)
+
+   Type the number of the license you wish to use or ? to try again:: 1
+   Do you want to set other trove identifiers (y/n) [n]: n
+   Wrote "setup.cfg".
+
+
+A setup.cfg file is created, containing the metadata of your project and the
+list of the packages it contains::
+
+   $ cat setup.cfg
+   [metadata]
+   name = CLVault
+   version = 0.1
+   author = Tarek Ziade
+   author_email = tarek@ziade.org
+   description = Command-line utility to store and retrieve passwords
+   home_page = http://bitbucket.org/tarek/clvault
+
+   classifier = Development Status :: 3 - Alpha
+       License :: OSI Approved :: GNU General Public License (GPL)
+
+   [files]
+   packages = clvault
+
+
+Our project will depend on the *keyring* project. Let's add it in the
+[metadata] section::
+
+   [metadata]
+   ...
+   requires_dist =
+       keyring
+
+
+Running commands
+----------------
+
+You can run useful commands on your project once the setup.cfg file is ready:
+
+- sdist: creates a source distribution
+- register: register your project to PyPI
+- upload: upload the distribution to PyPI
+- install_dist: install it
+
+All commands are run using the run script::
+
+   $ pysetup run install_dist
+   $ pysetup run sdist
+   $ pysetup run upload
+
+If you want to push a source distribution of your project to PyPI, do::
+
+   $ pysetup run sdist register upload
+
+
+Installing the project
+----------------------
+
+The project can be installed by manually running the packaging install command::
+
+   $ pysetup run install_dist

+
+***************************************
+Uploading Packages to the Package Index
+***************************************
+
+The Python Package Index (PyPI) not only stores the package info, but also the
+package data if the author of the package wishes to. The packaging command
+:command:`upload` pushes the distribution files to PyPI.
+
+The command is invoked immediately after building one or more distribution
+files.  For example, the command ::
+
+    python setup.py sdist bdist_wininst upload
+
+will cause the source distribution and the Windows installer to be uploaded to
+PyPI.  Note that these will be uploaded even if they are built using an earlier
+invocation of :file:`setup.py`, but that only distributions named on the command
+line for the invocation including the :command:`upload` command are uploaded.
+
+The :command:`upload` command uses the username, password, and repository URL
+from the :file:`$HOME/.pypirc` file (see section :ref:`packaging-pypirc` for more on this
+file). If a :command:`register` command was previously called in the same
+command, and if the password was entered in the prompt, :command:`upload` will
+reuse the entered password. This is useful if you do not want to store a clear
+text password in the :file:`$HOME/.pypirc` file.
+
+You can specify another PyPI server with the :option:`--repository=*url*`
+option::
+
+    python setup.py sdist bdist_wininst upload -r http://example.com/pypi
+
+See section :ref:`packaging-pypirc` for more on defining several servers.
+
+You can use the :option:`--sign` option to tell :command:`upload` to sign each
+uploaded file using GPG (GNU Privacy Guard).  The :program:`gpg` program must
+be available for execution on the system :envvar:`PATH`.  You can also specify
+which key to use for signing using the :option:`--identity=*name*` option.
+
+Other :command:`upload` options include :option:`--repository=<url>` or
+:option:`--repository=<section>` where *url* is the url of the server and
+*section* the name of the section in :file:`$HOME/.pypirc`, and
+:option:`--show-response` (which displays the full response text from the PyPI
+server for help in debugging upload problems).
+
+PyPI package display
+====================
+
+The ``description`` field plays a special role at PyPI. It is used by
+the server to display a home page for the registered package.
+
+If you use the `reStructuredText <http://docutils.sourceforge.net/rst.html>`_
+syntax for this field, PyPI will parse it and display an HTML output for
+the package home page.
+
+The ``description`` field can be filled from a text file located in the
+project::
+
+    from packaging.core import setup
+
+    fp = open('README.txt')
+    try:
+        description = fp.read()
+    finally:
+        fp.close()
+
+    setup(name='Packaging',
+          description=description)
+
+In that case, :file:`README.txt` is a regular reStructuredText text file located
+in the root of the package besides :file:`setup.py`.
+
+To prevent registering broken reStructuredText content, you can use the
+:program:`rst2html` program that is provided by the :mod:`docutils` package
+and check the ``description`` from the command line::
+
+    $ python setup.py --description | rst2html.py > output.html
+
+:mod:`docutils` will display a warning if there's something wrong with your
+syntax.
