+This guide is split into a simple overview followed by a longer presentation of

-Introduction
-============
+.. TODO integrate install and pysetup instead of duplicating
-Although Python's extensive standard library covers many programming needs,
-there often comes a time when you need to add some 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.
+.. toctree::
+ :maxdepth: 2
+ :numbered:
-In the past, there has been 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.
-
-This document is aimed primarily at the 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 some
-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:`distutils-index` manual.
-
-
-.. _inst-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 is installed just like any other software on your platform. For example,
-the module 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-based Linux
-systems, and so forth.
-
-In that case, you would download the installer appropriate to your platform and
-do the obvious thing with it: run it if it's an executable installer, ``rpm
---install`` it if it's an RPM, etc. You don't need to run Python or a setup
-script, you don't need to compile anything---you might not even need to read any
-instructions (although it's always a good idea to do so anyways).
-
-Of course, things will not always be that easy. You might be interested in a
-module distribution that 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 is about building and installing
-modules from standard source distributions.
-
-
-.. _inst-new-standard:
-
-The new standard: Distutils
----------------------------
-
-If you download a module source distribution, you can tell pretty quickly if it
-was packaged and distributed in the standard way, i.e. using the 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 will contain a setup script :file:`setup.py`, and a file named
-:file:`README.txt` or possibly just :file:`README`, which should explain that
-building and installing the module distribution is a simple matter of running ::
-
- python setup.py install
-
-If all these things are true, then you already know how to build and install the
-modules you've just downloaded: Run the command above. Unless you need to
-install things in a non-standard way or customize the build process, you don't
-really need this manual. Or rather, the above command is everything you need to
-get out of this manual.
-
-
-.. _inst-standard-install:
-
-Standard Build and Install
-==========================
-
-As described in section :ref:`inst-new-standard`, building and installing a module
-distribution using the Distutils is usually one simple command::
-
- python setup.py install
-
-On Unix, you'd run this command from a shell prompt; on Windows, you have to
-open a command prompt window ("DOS box") and do it there; on Mac OS X, you open
-a :command:`Terminal` window to get a shell prompt.
-
-
-.. _inst-platform-variations:
-
-Platform variations
--------------------
-
-You should always run the setup command from the distribution root directory,
-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 thing to do is::
-
- gunzip -c foo-1.0.tar.gz | tar xf - # unpacks into directory foo-1.0
- cd foo-1.0
- python setup.py install
-
-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`; you can use either a archive manipulator with a
-graphical user interface (such as WinZip) or a command-line tool (such as
-:program:`unzip` or :program:`pkunzip`) to unpack the archive. Then, open a
-command prompt window ("DOS box"), and run::
-
- cd c:\Temp\foo-1.0
- python setup.py install
-
-
-.. _inst-splitting-up:
-
-Splitting the job up
---------------------
-
-Running ``setup.py install`` builds and installs all modules in one run. 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 particularly helpful when the build and install
-will be done by different users---for example, you might want to build a module
-distribution and hand it off to a system administrator for installation (or do
-it yourself, with super-user privileges).
-
-For example, you can build everything in one step, and then install everything
-in a second step, by invoking the setup script twice::
-
- python setup.py build
- python setup.py install
-
-If you do this, you will notice that running the :command:`install` command
-first runs the :command:`build` command, which---in this case---quickly notices
-that it has nothing to do, since everything in the :file:`build` directory is
-up-to-date.
-
-You may not need this ability to break things down often if all you do is
-install modules downloaded off the 'net, but it's very handy for more advanced
-tasks. If you get into distributing your own Python modules and extensions,
-you'll run lots of individual Distutils commands on their own.
-
-
-.. _inst-how-build-works:
-
-How building works
-------------------
-
-As implied above, the :command:`build` command is responsible for putting the
-files to install 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 change the build directory with the
-:option:`--build-base` option. For example::
-
- python setup.py build --build-base=/tmp/pybuild/foo-1.0
-
-(Or you could do this permanently with a directive in your system or personal
-Distutils configuration file; see section :ref:`inst-config-files`.) Normally, this
-isn't necessary.
-
-The default layout for the build tree is as follows::
-
- --- 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"---that is, 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 by the compile/link process that don't actually get
-installed. In either case, the :file:`lib` (or :file:`lib.{plat}`) directory
-contains all Python modules (pure Python and extensions) that will be installed.
-
-In the future, more directories will be added to handle Python scripts,
-documentation, binary executables, and whatever else is needed to handle the job
-of installing Python modules and applications.
-
-
-.. _inst-how-install-works:
-
-How installation works
-----------------------
-
-After the :command:`build` command runs (whether you run it explicitly, or the
-:command:`install` command does it for you), the work of the :command:`install`
-command is relatively simple: all it has to do is copy everything under
-:file:`build/lib` (or :file:`build/lib.{plat}`) to your chosen installation
-directory.
-
-If you don't choose an installation directory---i.e., if you just run ``setup.py
-install``\ ---then the :command:`install` command installs to the standard
-location for third-party Python modules. This location varies by platform and
-by 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"):
-
-+-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
-| Platform | Standard installation location | Default value | Notes |
-+=================+=====================================================+==================================================+=======+
-| Unix (pure) | :file:`{prefix}/lib/python{X.Y}/site-packages` | :file:`/usr/local/lib/python{X.Y}/site-packages` | \(1) |
-+-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
-| Unix (non-pure) | :file:`{exec-prefix}/lib/python{X.Y}/site-packages` | :file:`/usr/local/lib/python{X.Y}/site-packages` | \(1) |
-+-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
-| Windows | :file:`{prefix}\\Lib\\site-packages` | :file:`C:\\Python{XY}\\Lib\\site-packages` | \(2) |
-+-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
-
-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. Under Unix, just type ``python`` at the shell prompt. Under
-Windows, choose :menuselection:`Start --> Programs --> Python X.Y -->
-Python (command line)`. 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 2.4 (#26, Aug 7 2004, 17:19:02)
- 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:`inst-alt-install`. If you want to customize your
-installation directories more heavily, see section :ref:`inst-custom-install` on
-custom installations.
-
-
-.. _inst-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 Distutils :command:`install` 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` 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.
-
-
-.. _inst-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 idea 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/`.
-This scheme can be used by anyone, regardless of the operating system they
-are installing for.
-
-Installing a new module distribution is as simple as ::
-
- python setup.py install --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` command
-will expand this to your home directory::
-
- python setup.py install --home=~
-
-The :option:`--home` option defines the installation base directory. Files are
-installed to the following directories under the installation base as follows:
-
-+------------------------------+---------------------------+-----------------------------+
-| Type of file | Installation Directory | Override option |

-
-Alternate installation: Unix (the prefix scheme)
-------------------------------------------------
-
-The "prefix scheme" is useful when you wish to use one Python installation to
-perform the build/install (i.e., to run the setup script), 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 ::
-
- /usr/bin/python setup.py install --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 ::
-
- /usr/local/bin/python setup.py install --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 ``python setup.py install`` without any other options,
-you're using it.
-
-Note that installing extensions to an alternate Python installation has no
-effect on how those extensions are built: in particular, the Python header files
-(:file:`Python.h` and friends) installed with the Python interpreter used to run
-the setup script will be used in compiling extensions. It is your
-responsibility to ensure that the interpreter used to run extensions installed
-in this way is compatible with the interpreter used to build them. The best way
-to do this is to ensure 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.)
-
-
-.. _inst-alt-install-windows:
-
-Alternate installation: Windows (the prefix scheme)
----------------------------------------------------
-
-Windows has no concept of a user's home directory, and since the standard Python
-installation under Windows is simpler than under Unix, the :option:`--prefix`
-option has traditionally been used to install additional packages in separate
-locations on Windows. ::
-
- python setup.py install --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 not supported 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` |
-+------------------------------+---------------------------+-----------------------------+
-
-
-.. _inst-custom-install:
-
-Custom Installation
-===================
-
-Sometimes, the alternate installation schemes described in section
-:ref:`inst-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; in this case, it makes most sense to supply
-a relative path, which will be interpreted relative to the installation base
-directory (your home directory, in this case)::
-
- python setup.py install --home=~ --install-scripts=scripts
-
-Another Unix example: suppose your Python installation was built and installed
-with a prefix of :file:`/usr/local/python`, so under 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::
-
- python setup.py install --install-scripts=/usr/local/bin
-
-(This performs an installation using the "prefix scheme," where the prefix is
-whatever your Python interpreter was installed with--- :file:`/usr/local/python`
-in this case.)
-
-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::
-
- python setup.py install --install-purelib=Site --install-platlib=Site
-
-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:`inst-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. The recommended way to do this is to
-supply relative paths; 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::
-
- python setup.py install --home=~ \
- --install-purelib=python/lib \
- --install-platlib=python/lib.$PLAT \
- --install-scripts=python/scripts
- --install-data=python/data
-
-or, equivalently, ::
-
- python setup.py install --home=~/python \
- --install-purelib=lib \
- --install-platlib='lib.$PLAT' \
- --install-scripts=scripts
- --install-data=data
-
-``$PLAT`` is not (necessarily) an environment variable---it will be expanded by
-the Distutils as it parses your command line options, just as it does when
-parsing your configuration file(s).
-
-Obviously, specifying the entire installation scheme every time you install a
-new module distribution would be very tedious. Thus, you can put these options
-into your Distutils config file (see section :ref:`inst-config-files`)::
-
- [install]
- install-base=$HOME
- install-purelib=python/lib
- install-platlib=python/lib.$PLAT
- install-scripts=python/scripts
- install-data=python/data
-
-or, equivalently, ::
-
- [install]
- install-base=$HOME/python
- install-purelib=lib
- install-platlib=lib.$PLAT
- install-scripts=scripts
- install-data=data
-
-Note that these two are *not* equivalent if you supply a different installation
-base directory when you run the setup script. For example, ::
-
- python setup.py install --install-base=/tmp
-
-would install pure modules to :file:`{/tmp/python/lib}` in the first case, and
-to :file:`{/tmp/lib}` in the second case. (For the second case, you probably
-want to supply an installation base of :file:`/tmp/python`.)
-
-You probably noticed the use of ``$HOME`` and ``$PLAT`` in the sample
-configuration file input. These are Distutils configuration variables, which
-bear a strong resemblance to environment variables. In fact, you can use
-environment variables in config files on platforms that have such a notion but
-the Distutils additionally define a few extra variables that may not be in your
-environment, such as ``$PLAT``. (And of course, on systems that don't have
-environment variables, such as Mac OS 9, the configuration variables supplied by
-the Distutils are the only ones you can use.) See section :ref:`inst-config-files`
-for details.
-
-.. XXX need some Windows examples---when would custom installation schemes be
- needed on those platforms?
-
-
-.. XXX I'm not sure where this section should go.
-
-.. _inst-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 the path is configured into the Python binary when the interpreter is built.
-You can determine the 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 install Python
-modules into some arbitrary directory. For example, your site may have a
-convention of keeping all software related to the web server under :file:`/www`.
-Add-on Python modules might then belong in :file:`/www/python`, and in order to
-import them, this directory must be added to ``sys.path``. There are several
-different ways to add the directory.
-
-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 2.2 to 2.2.2, 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.
-
-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 paths that don't
-exist.)
-
-Finally, ``sys.path`` is just a regular Python list, so any Python application
-can modify it by adding or removing entries.
-
-
-.. _inst-config-files:
-
-Distutils Configuration Files
-=============================
-
-As mentioned above, you can use Distutils configuration files to record personal
-or site preferences for any Distutils options. That is, any option to any
-command can be stored in one of two or three (depending on your platform)
-configuration files, which will be consulted before the command-line is parsed.
-This means that configuration files will override default values, and the
-command-line will in turn override configuration files. Furthermore, if
-multiple configuration files apply, values from "earlier" files are overridden
-by "later" files.
-
-
-.. _inst-config-filenames:
-
-Location and names of config files
-----------------------------------
-
-The names and locations of the configuration files vary slightly across
-platforms. On Unix and Mac OS X, the three configuration files (in the order
-they are processed) are:
-
-+--------------+----------------------------------------------------------+-------+
-| Type of file | Location and filename | Notes |
-+==============+==========================================================+=======+
-| system | :file:`{prefix}/lib/python{ver}/distutils/distutils.cfg` | \(1) |
-+--------------+----------------------------------------------------------+-------+
-| personal | :file:`$HOME/.pydistutils.cfg` | \(2) |
-+--------------+----------------------------------------------------------+-------+
-| local | :file:`setup.cfg` | \(3) |
-+--------------+----------------------------------------------------------+-------+
-
-And on Windows, the configuration files are:
-
-+--------------+-------------------------------------------------+-------+
-| Type of file | Location and filename | Notes |
-+==============+=================================================+=======+
-| system | :file:`{prefix}\\Lib\\distutils\\distutils.cfg` | \(4) |
-+--------------+-------------------------------------------------+-------+
-| personal | :file:`%HOME%\\pydistutils.cfg` | \(5) |
-+--------------+-------------------------------------------------+-------+
-| local | :file:`setup.cfg` | \(3) |
-+--------------+-------------------------------------------------+-------+
-
-On all platforms, the "personal" file can be temporarily disabled by
-passing the `--no-user-cfg` option.
-
-Notes:
-
-(1)
- Strictly speaking, the system-wide configuration file lives in the directory
- where the Distutils are installed; under Python 1.6 and later on Unix, this is
- as shown. For Python 1.5.2, the Distutils will normally be installed to
- :file:`{prefix}/lib/python1.5/site-packages/distutils`, so the system
- configuration file should be put there under Python 1.5.2.
-
-(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. This is done by the :func:`os.path.expanduser`
- function used by Distutils.
-
-(3)
- I.e., in the current directory (usually the location of the setup script).
-
-(4)
- (See also note (1).) Under Python 1.6 and later, Python's default "installation
- prefix" is :file:`C:\\Python`, so the system configuration file is normally
- :file:`C:\\Python\\Lib\\distutils\\distutils.cfg`. Under Python 1.5.2, the
- default prefix was :file:`C:\\Program Files\\Python`, and the Distutils were not
- part of the standard library---so the system configuration file would be
- :file:`C:\\Program Files\\Python\\distutils\\distutils.cfg` in a standard Python
- 1.5.2 installation under Windows.
-
-(5)
- On Windows, if the :envvar:`HOME` environment variable is not defined,
- :envvar:`USERPROFILE` then :envvar:`HOMEDRIVE` and :envvar:`HOMEPATH` will
- be tried. This is done by the :func:`os.path.expanduser` function used
- by Distutils.
-
-
-.. _inst-config-syntax:
-
-Syntax of config files
-----------------------
-
-The Distutils configuration files all have the same syntax. The config files
-are grouped into sections. There is one section for each Distutils command,
-plus a ``global`` section for global options that affect every command. Each
-section consists of one option per line, specified as ``option=value``.
-
-For example, the following is a complete config file that just forces all
-commands to run quietly by default::
-
- [global]
- verbose=0
-
-If this is installed as the system config file, it will affect all processing of
-any Python module distribution by any user on the current system. If it is
-installed as your personal config file (on systems that support them), it will
-affect only module distributions processed by you. And if it is used as the
-:file:`setup.cfg` for a particular module distribution, it affects only that
-distribution.
-
-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 ::
-
- python setup.py 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 config files has no
-such implication; it only means that if the command is run, the options in the
-config file will apply. (Or if other commands that derive values from it are
-run, they will use the values in the config file.)
-
-You can find out the complete list of options for any command using the
-:option:`--help` option, e.g.::
-
- python setup.py build --help
-
-and you can find out the complete list of global options by using
-:option:`--help` without a command::
-
- python setup.py --help
-
-See also the "Reference" section of the "Distributing Python Modules" manual.
-
-
-.. _inst-building-ext:
-
-Building Extensions: Tips and Tricks
-====================================
-
-Whenever possible, the Distutils try to use the configuration information made
-available by the Python interpreter used to run the :file:`setup.py` script.
-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 Distutils behaviour.
-
-
-.. _inst-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.
-
-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 ``python setup.py 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.

-Borland/CodeGear C++
-^^^^^^^^^^^^^^^^^^^^
-
-This subsection describes the necessary steps to use Distutils 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 Distutils manage to use these libraries with their changed names? If
-the extension needs a library (eg. :file:`foo`) Distutils 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 Distutils compile your extension with Borland C++ you now have to type::
-
- python setup.py 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 Distutils (see
-section :ref:`inst-config-files`.)

-GNU C / Cygwin / MinGW
-^^^^^^^^^^^^^^^^^^^^^^
-
-This section describes the necessary steps to use Distutils 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 Distutils compile your extension with Cygwin you have to type::
-

+Installing Python projects: overwiew
+====================================
+
+.. _packaging_packaging-intro:
+
+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"):
+
++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
+| Platform | Standard installation location | Default value | Notes |
++=================+=====================================================+==================================================+=======+
+| Unix (pure) | :file:`{prefix}/lib/python{X.Y}/site-packages` | :file:`/usr/local/lib/python{X.Y}/site-packages` | \(1) |
++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
+| Unix (non-pure) | :file:`{exec-prefix}/lib/python{X.Y}/site-packages` | :file:`/usr/local/lib/python{X.Y}/site-packages` | \(1) |
++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
+| Windows | :file:`{prefix}\\Lib\\site-packages` | :file:`C:\\Python{XY}\\Lib\\site-packages` | \(2) |
++-----------------+-----------------------------------------------------+--------------------------------------------------+-------+
+
+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
+----------------------------------------
+
+.. sectionauthor:: Rene Liebscher <R.Liebscher at gmx.de>
+
+
+
+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>`_
+ Information about building the required libraries for the MinGW
+ environment.
+
+
+.. rubric:: Footnotes
+
+.. [#] This also means you could replace all existing COFF-libraries with
+ OMF-libraries of the same name.
+
+.. [#] Check http://sources.redhat.com/cygwin/ and http://www.mingw.org/ for
+ more information.
+
+.. [#] Then you have no POSIX emulation available, but you also don't need

+
+================
+Pysetup Tutorial
+================
+
+Getting started
+---------------
+
+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::
+

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

+
+
+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``.

+
+: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.compiler.extension` --- The Extension class
+===========================================================
+
+.. module:: packaging.compiler.extension
+ :synopsis: Class used to represent C/C++ extension modules.
+
+
+This module provides the :class:`Extension` class, used to represent C/C++
+extension modules.
+
+.. class:: Extension
+
+ The Extension class describes a single C or C++ extension module. It accepts
+ the following keyword arguments in its constructor
+
+ +------------------------+--------------------------------+---------------------------+
+ | argument name | value | type |
+ +========================+================================+===========================+
+ | *name* | the full name of the | string |

+ +------------------------+--------------------------------+---------------------------+
+ | *sources* | list of source filenames, | string |
+ | | relative to the distribution | |
+ | | root (where the setup script | |
+ | | lives), in Unix form (slash- | |
+ | | separated) for portability. | |
+ | | Source files may be C, C++, | |

+: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.
+

+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:
+
+.. code-block:: none

+: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;
+ 'generate' can suggest it creates a file or an image, use 'make'
+
+.. 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.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.
+

+: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)'``.
+
+ .. XXX are requirements comma-separated?
+
+ If you want to use another index than the main PyPI, give its URI as *index*
+ argument.
+
+ *installed* is a list of already installed distributions used to find
+ satisfied dependencies, obsoleted distributions and eventual conflicts.
+
+ By default, alpha, beta and candidate versions are not picked up. Set
+ *prefer_final* to false to accept them too.
+
+ The results are returned in a dictionary containing all the information
+ needed to perform installation of the requirements with the
+ :func:`install_from_infos` function:
+
+ >>> get_install_info("FooBar (<=1.2)")
+ {'install': [<FooBar 1.1>], 'remove': [], 'conflict': []}
+
+ .. TODO should return tuple or named tuple, not dict
+ .. TODO use "predicate" or "requirement" consistently in version and here
+ .. FIXME "info" cannot be plural in English, s/infos/info/
+
+
+.. 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
+ .. TODO document integration with default schemes, esp. user site-packages
+
+
+.. function:: install_local_project(path)
+
+ Install a distribution from a source directory, which must contain either a
+ Packaging-compliant :file:`setup.cfg` file or a legacy Distutils
+ :file:`setup.py` script (in which case Distutils will be used under the hood
+ to perform the installation).
+
+
+.. function:: remove(project_name, paths=None, auto_confirm=True)
+
+ Remove one distribution from the system.
+
+ .. FIXME this is the only function using "project" instead of dist/release
+

+: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,

+ ...
+ >>> 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`.

+: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">]

+:mod:`packaging.pypi.xmlrpc` --- Crawler using the PyPI XML-RPC interface
+=========================================================================
+
+.. 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.

+: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:
+

+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:

+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``.

+
+
+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.

+
+Pure Python distribution (by module)
+====================================
+
+If you're just distributing a couple of modules, especially if they don't live
+in a particular package, you can specify them individually using the
+:option:`py_modules` option in the setup script.
+
+In the simplest case, you'll have two files to worry about: a setup script and
+the single module you're distributing, :file:`foo.py` in this example::
+
+ <root>/
+ 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 at 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
+ be run from this directory.

+
+**********************************
+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

+ 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

+.. _packaging-setup-script:
+
+************************
+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 at 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)
+
++----------------------+---------------------------+-----------------+--------+
+| Meta-Data | Description | Value | Notes |
++======================+===========================+=================+========+
+| ``name`` | name of the project | short string | \(1) |
++----------------------+---------------------------+-----------------+--------+

++----------------------+---------------------------+-----------------+--------+
+| ``platforms`` | a list of platforms | list of strings | |
++----------------------+---------------------------+-----------------+--------+
+| ``license`` | license for the release | short string | \(6) |
++----------------------+---------------------------+-----------------+--------+
+
+Notes:
+
+(1)
+ These fields are required.
+
+(2)
+ It is recommended that versions take the form *major.minor[.patch[.sub]]*.
+
+(3)
+ Either the author or the maintainer must be identified.
+
+(4)
+ The list of classifiers is available from the `PyPI website
+ <http://pypi.python.org/pypi>`_. See also :mod:`packaging.create`.
+
+(5)
+ The ``description`` field is used by PyPI when you are registering a
+ release, to build its PyPI page.
+
+(6)
+ The ``license`` field is a text indicating the license covering the
+ distribution where the license is not a selection from the "License" Trove
+ classifiers. See the ``Classifier`` field. Notice that
+ there's a ``licence`` distribution option which is deprecated but still
+ acts as an alias for ``license``.
+
+'short string'
+ A single line of text, not more than 200 characters.
+
+'long string'
+ Multiple lines of plain text in reStructuredText format (see
+ http://docutils.sf.net/).
+
+'list of strings'
+ See below.
+
+In Python 2.x, "string value" means a unicode object. If a byte string (str or
+bytes) is given, it has to be valid ASCII.
+
+.. TODO move this section to the version document, keep a summary, add a link
+
+Encoding the version information is an art in itself. Python projects generally
+adhere to the version format *major.minor[.patch][sub]*. The major number is 0
+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:
+
+0.1.0
+ the first, experimental release of a project
+
+1.0.1a2
+ the second alpha release of the first patch version of 1.0
+
+:option:`classifiers` are specified in a Python list::
+
+ setup(...,
+ classifiers=[
+ 'Development Status :: 4 - Beta',
+ 'Environment :: Console',
+ 'Environment :: Web Environment',
+ 'Intended Audience :: End Users/Desktop',
+ 'Intended Audience :: Developers',
+ 'Intended Audience :: System Administrators',
+ 'License :: OSI Approved :: Python Software Foundation License',
+ 'Operating System :: MacOS :: MacOS X',
+ 'Operating System :: Microsoft :: Windows',
+ 'Operating System :: POSIX',
+ 'Programming Language :: Python',
+ 'Topic :: Communications :: Email',
+ 'Topic :: Office/Business',
+ '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:`include pat1 pat2 ...` | include all files matching any of the listed |
+| | patterns |
++-------------------------------------------+-----------------------------------------------+
+| :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 at 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 at 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

+.. _packaging-package-upload:
+
+***************************************
+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.

+Python の開発は、1990 年ごろから開始されています。
+開発者の Guido van Rossum は教育用のプログラミング言語「ABC」の開発に参加していましたが、ABC は実用上の目的にはあまり適していませんでした。
+このため、Guido はより実用的なプログラミング言語の開発を開始し、英国 BBS 放送のコメディ番組「モンティ パイソン」のファンである Guido はこの言語を「Python」と名づけました。
+このような背景から生まれた Python の言語設計は、「シンプル」で「習得が容易」という目標に重点が置かれています。
+多くのスクリプト系言語ではユーザの目先の利便性を優先して色々な機能を言語要素として取り入れる場合が多いのですが、Python ではそういった小細工が追加されることはあまりありません。
+言語自体の機能は最小限に押さえ、必要な機能は拡張モジュールとして追加する、というのが Python のポリシーです。
