Installing and Using Setuptools
===============================

.. contents:: **Table of Contents**


-------------------------
Installation Instructions
-------------------------

The recommended way to bootstrap setuptools on any system is to download
`ez_setup.py`_ and run it using the target Python environment. Different
operating systems have different recommended techniques to accomplish this
basic routine, so below are some examples to get you started.

Setuptools requires Python 2.6 or later. To install setuptools
on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
<https://bitbucket.org/pypa/setuptools/raw/bootstrap-py24/ez_setup.py>`_.

The link provided to ez_setup.py is a bookmark to bootstrap script for the
latest known stable release.

.. _ez_setup.py: https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py

Windows 8 (Powershell)
======================

For best results, uninstall previous versions FIRST (see `Uninstalling`_).

Using Windows 8 or later, it's possible to install with one simple Powershell
command. Start up Powershell and paste this command::

    > (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | python -

You must start the Powershell with Administrative privileges or you may choose
to install a user-local installation::

    > (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | python - --user

If you have Python 3.3 or later, you can use the ``py`` command to install to
different Python versions. For example, to install to Python 3.3 if you have
Python 2.7 installed::

    > (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | py -3 -

The recommended way to install setuptools on Windows is to download
`ez_setup.py`_ and run it. The script will download the appropriate .egg
file and install it for you.

Once installation is complete, you will find an ``easy_install`` program in
your Python ``Scripts`` subdirectory.  For simple invocation and best results,
add this directory to your ``PATH`` environment variable, if it is not already
present. If you did a user-local install, the ``Scripts`` subdirectory is
``$env:APPDATA\Python\Scripts``.


Windows 7 (or graphical install)
================================

For Windows 7 and earlier, download `ez_setup.py`_ using your favorite web
browser or other technique and "run" that file.


Unix (wget)
===========

Most Linux distributions come with wget.

Download `ez_setup.py`_ and run it using the target Python version. The script
will download the appropriate version and install it for you::

    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python

Note that you will may need to invoke the command with superuser privileges to
install to the system Python::

    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python

Alternatively, Setuptools may be installed to a user-local path::

    > wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python - --user

Unix including Mac OS X (curl)
==============================

If your system has curl installed, follow the ``wget`` instructions but
replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::

    > curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -o - | python


Advanced Installation
=====================

For more advanced installation options, such as installing to custom
locations or prefixes, download and extract the source
tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
and run setup.py with any supported distutils and Setuptools options.
For example::

    setuptools-x.x$ python setup.py install --prefix=/opt/setuptools

Use ``--help`` to get a full options list, but we recommend consulting
the `EasyInstall manual`_ for detailed instructions, especially `the section
on custom installation locations`_.

.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#custom-installation-locations


Downloads
=========

All setuptools downloads can be found at `the project's home page in the Python
Package Index`_.  Scroll to the very bottom of the page to find the links.

.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools

In addition to the PyPI downloads, the development version of ``setuptools``
is available from the `Bitbucket repo`_, and in-development versions of the
`0.6 branch`_ are available as well.

.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06

Uninstalling
============

On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
installer, simply use the uninstall feature of "Add/Remove Programs" in the
Control Panel.

Otherwise, to uninstall Setuptools or Distribute, regardless of the Python
version, delete all ``setuptools*`` and ``distribute*`` files and
directories from your system's ``site-packages`` directory
(and any other ``sys.path`` directories) FIRST.

If you are upgrading or otherwise plan to re-install Setuptools or Distribute,
nothing further needs to be done. If you want to completely remove Setuptools,
you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts
and associated executables installed to the Python scripts directory.

--------------------------------
Using Setuptools and EasyInstall
--------------------------------

Here are some of the available manuals, tutorials, and other resources for
learning about Setuptools, Python Eggs, and EasyInstall:

* `The EasyInstall user's guide and reference manual`_
* `The setuptools Developer's Guide`_
* `The pkg_resources API reference`_
* `Package Compatibility Notes`_ (user-maintained)
* `The Internal Structure of Python Eggs`_

Questions, comments, and bug reports should be directed to the `distutils-sig
mailing list`_.  If you have written (or know of) any tutorials, documentation,
plug-ins, or other resources for setuptools users, please let us know about
them there, so this reference list can be updated.  If you have working,
*tested* patches to correct problems or add features, you may submit them to
the `setuptools bug tracker`_.

Credits
-------

* The original design for the ``.egg`` format and the ``pkg_resources`` API was
  co-created by Phillip Eby and Bob Ippolito.  Bob also implemented the first
  version of ``pkg_resources``, and supplied the OS X operating system version
  compatibility algorithm.

* Ian Bicking implemented many early "creature comfort" features of
  easy_install, including support for downloading via Sourceforge and
  Subversion repositories.  Ian's comments on the Web-SIG about WSGI
  application deployment also inspired the concept of "entry points" in eggs,
  and he has given talks at PyCon and elsewhere to inform and educate the
  community about eggs and setuptools.

* Jim Fulton contributed time and effort to build automated tests of various
  aspects of ``easy_install``, and supplied the doctests for the command-line
  ``.exe`` wrappers on Windows.

* Phillip J. Eby is the seminal author of setuptools, and
  first proposed the idea of an importable binary distribution format for
  Python application plug-ins.

* Significant parts of the implementation of setuptools were funded by the Open
  Source Applications Foundation, to provide a plug-in infrastructure for the
  Chandler PIM application.  In addition, many OSAF staffers (such as Mike
  "Code Bear" Taylor) contributed their time and stress as guinea pigs for the
  use of eggs and setuptools, even before eggs were "cool".  (Thanks, guys!)

* Tarek Ziadé is the principal author of the Distribute fork, which
  re-invigorated the community on the project, encouraged renewed innovation,
  and addressed many defects.

* Since the merge with Distribute, Jason R. Coombs is the
  maintainer of setuptools.  The project is maintained in coordination with
  the Python Packaging Authority (PyPA) and the larger Python community.

* `Issue #162 <https://bitbucket.org/pypa/setuptools/issue/162>`_: Update dependency on certifi to 1.0.1.
* `Issue #164 <https://bitbucket.org/pypa/setuptools/issue/164>`_: Update dependency on wincertstore to 0.2.

---
3.1
---

* `Issue #161 <https://bitbucket.org/pypa/setuptools/issue/161>`_: Restore Features functionality to allow backward compatibility
  (for Features) until the uses of that functionality is sufficiently removed.

-----
3.0.2
-----

* Correct typo in previous bugfix.

-----
3.0.1
-----

* `Issue #157 <https://bitbucket.org/pypa/setuptools/issue/157>`_: Restore support for Python 2.6 in bootstrap script where
  ``zipfile.ZipFile`` does not yet have support for context managers.

---
3.0
---

* `Issue #125 <https://bitbucket.org/pypa/setuptools/issue/125>`_: Prevent Subversion support from creating a ~/.subversion
  directory just for checking the presence of a Subversion repository.
* `Issue #12 <https://bitbucket.org/pypa/setuptools/issue/12>`_: Namespace packages are now imported lazily.  That is, the mere
  declaration of a namespace package in an egg on ``sys.path`` no longer
  causes it to be imported when ``pkg_resources`` is imported.  Note that this
  change means that all of a namespace package's ``__init__.py`` files must
  include a ``declare_namespace()`` call in order to ensure that they will be
  handled properly at runtime.  In 2.x it was possible to get away without
  including the declaration, but only at the cost of forcing namespace
  packages to be imported early, which 3.0 no longer does.
* `Issue #148 <https://bitbucket.org/pypa/setuptools/issue/148>`_: When building (bdist_egg), setuptools no longer adds
  ``__init__.py`` files to namespace packages. Any packages that rely on this
  behavior will need to create ``__init__.py`` files and include the
  ``declare_namespace()``.
* `Issue #7 <https://bitbucket.org/pypa/setuptools/issue/7>`_: Setuptools itself is now distributed as a zip archive in addition to
  tar archive. ez_setup.py now uses zip archive. This approach avoids the potential
  security vulnerabilities presented by use of tar archives in ez_setup.py.
  It also leverages the security features added to ZipFile.extract in Python 2.7.4.
* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Removed deprecated Features functionality.
* `Pull Request #28 <https://bitbucket.org/pypa/setuptools/pull-request/28>`_: Remove backport of ``_bytecode_filenames`` which is
  available in Python 2.6 and later, but also has better compatibility with
  Python 3 environments.
* `Issue #156 <https://bitbucket.org/pypa/setuptools/issue/156>`_: Fix spelling of __PYVENV_LAUNCHER__ variable.

* `Issue #144 <https://bitbucket.org/pypa/setuptools/issue/144>`_: Read long_description using codecs module to avoid errors
  installing on systems where LANG=C.

-----
2.1.1
-----

* `Issue #139 <https://bitbucket.org/pypa/setuptools/issue/139>`_: Fix regression in re_finder for CVS repos (and maybe Git repos
  as well).

---
2.1
---

  in a zip-imported file.
* `Issue #131 <https://bitbucket.org/pypa/setuptools/issue/131>`_: Fix RuntimeError when constructing an egg fetcher.

-----
2.0.2
-----

* Fix NameError during installation with Python implementations (e.g. Jython)
  not containing parser module.
* Fix NameError in ``sdist:re_finder``.

-----
2.0.1
-----

---
2.0
---

* `Issue #121 <https://bitbucket.org/pypa/setuptools/issue/121>`_: Exempt lib2to3 pickled grammars from DirectorySandbox.
* `Issue #41 <https://bitbucket.org/pypa/setuptools/issue/41>`_: Dropped support for Python 2.4 and Python 2.5. Clients requiring
  setuptools for those versions of Python should use setuptools 1.x.
* Removed ``setuptools.command.easy_install.HAS_USER_SITE``. Clients
  expecting this boolean variable should use ``site.ENABLE_USER_SITE``
  instead.
* Removed ``pkg_resources.ImpWrapper``. Clients that expected this class
  should use ``pkgutil.ImpImporter`` instead.

-----
1.4.2
-----

* `Issue #116 <https://bitbucket.org/pypa/setuptools/issue/116>`_: Correct TypeError when reading a local package index on Python
  3.

-----
1.4.1
-----

* `Issue #114 <https://bitbucket.org/pypa/setuptools/issue/114>`_: Use ``sys.getfilesystemencoding`` for decoding config in
  ``bdist_wininst`` distributions.

* `Issue #105 <https://bitbucket.org/pypa/setuptools/issue/105>`_ and `Issue #113 <https://bitbucket.org/pypa/setuptools/issue/113>`_: Establish a more robust technique for
  determining the terminal encoding::

    1. Try ``getpreferredencoding``
    2. If that returns US_ASCII or None, try the encoding from
       ``getdefaultlocale``. If that encoding was a "fallback" because Python
       could not figure it out from the environment or OS, encoding remains
       unresolved.
    3. If the encoding is resolved, then make sure Python actually implements
       the encoding.
    4. On the event of an error or unknown codec, revert to fallbacks
       (UTF-8 on Darwin, ASCII on everything else).
    5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
       a bug on older Python releases.

    On a side note, it would seem that the encoding only matters for when SVN
    does not yet support ``--xml`` and when getting repository and svn version
    numbers. The ``--xml`` technique should yield UTF-8 according to some
    messages on the SVN mailing lists. So if the version numbers are always
    7-bit ASCII clean, it may be best to only support the file parsing methods
    for legacy SVN releases and support for SVN without the subprocess command
    would simple go away as support for the older SVNs does.

---
1.4
---

* `Issue #27 <https://bitbucket.org/pypa/setuptools/issue/27>`_: ``easy_install`` will now use credentials from .pypirc if
  present for connecting to the package index.
* `Pull Request #21 <https://bitbucket.org/pypa/setuptools/pull-request/21>`_: Omit unwanted newlines in ``package_index._encode_auth``
  when the username/password pair length indicates wrapping.

-----
1.3.2
-----

* `Issue #99 <https://bitbucket.org/pypa/setuptools/issue/99>`_: Fix filename encoding issues in SVN support.

-----
1.3.1
-----

* Remove exuberant warning in SVN support when SVN is not used.

---
1.3
---

* Address security vulnerability in SSL match_hostname check as reported in
  `Python #17997 <http://bugs.python.org/issue17997>`_.
* Prefer `backports.ssl_match_hostname
  <https://pypi.python.org/pypi/backports.ssl_match_hostname>`_ for backport
  implementation if present.
* Correct NameError in ``ssl_support`` module (``socket.error``).

---
1.2
---

* `Issue #26 <https://bitbucket.org/pypa/setuptools/issue/26>`_: Add support for SVN 1.7. Special thanks to Philip Thiem for the
  contribution.
* `Issue #93 <https://bitbucket.org/pypa/setuptools/issue/93>`_: Wheels are now distributed with every release. Note that as
  reported in `Issue #108 <https://bitbucket.org/pypa/setuptools/issue/108>`_, as of Pip 1.4, scripts aren't installed properly
  from wheels. Therefore, if using Pip to install setuptools from a wheel,
  the ``easy_install`` command will not be available.
* Setuptools "natural" launcher support, introduced in 1.0, is now officially
  supported.

-----
1.1.7
-----

* Fixed behavior of NameError handling in 'script template (dev).py' (script
  launcher for 'develop' installs).
* ``ez_setup.py`` now ensures partial downloads are cleaned up following
  a failed download.
* `Distribute #363 <https://bitbucket.org/tarek/distribute/issue/363>`_ and `Issue #55 <https://bitbucket.org/pypa/setuptools/issue/55>`_: Skip an sdist test that fails on locales
  other than UTF-8.

-----
1.1.6
-----

* `Distribute #349 <https://bitbucket.org/tarek/distribute/issue/349>`_: ``sandbox.execfile`` now opens the target file in binary
  mode, thus honoring a BOM in the file when compiled.

-----
1.1.5
-----

* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Second attempt at fix (logic was reversed).

-----
1.1.4
-----

* `Issue #77 <https://bitbucket.org/pypa/setuptools/issue/77>`_: Fix error in upload command (Python 2.4).

-----
1.1.3
-----

* Fix NameError in previous patch.

-----
1.1.2
-----

* `Issue #69 <https://bitbucket.org/pypa/setuptools/issue/69>`_: Correct issue where 404 errors are returned for URLs with
  fragments in them (such as #egg=).

-----
1.1.1
-----

* `Issue #75 <https://bitbucket.org/pypa/setuptools/issue/75>`_: Add ``--insecure`` option to ez_setup.py to accommodate
  environments where a trusted SSL connection cannot be validated.
* `Issue #76 <https://bitbucket.org/pypa/setuptools/issue/76>`_: Fix AttributeError in upload command with Python 2.4.

---
1.1
---

* `Issue #71 <https://bitbucket.org/pypa/setuptools/issue/71>`_ (`Distribute #333 <https://bitbucket.org/tarek/distribute/issue/333>`_): EasyInstall now puts less emphasis on the
  condition when a host is blocked via ``--allow-hosts``.
* `Issue #72 <https://bitbucket.org/pypa/setuptools/issue/72>`_: Restored Python 2.4 compatibility in ``ez_setup.py``.

---
1.0
---

* `Issue #60 <https://bitbucket.org/pypa/setuptools/issue/60>`_: On Windows, Setuptools supports deferring to another launcher,
  such as Vinay Sajip's `pylauncher <https://bitbucket.org/pypa/pylauncher>`_
  (included with Python 3.3) to launch console and GUI scripts and not install
  its own launcher executables. This experimental functionality is currently
  only enabled if  the ``SETUPTOOLS_LAUNCHER`` environment variable is set to
  "natural". In the future, this behavior may become default, but only after
  it has matured and seen substantial adoption. The ``SETUPTOOLS_LAUNCHER``
  also accepts "executable" to force the default behavior of creating launcher
  executables.
* `Issue #63 <https://bitbucket.org/pypa/setuptools/issue/63>`_: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or
  wget for retrieving the Setuptools tarball for improved security of the
  install. The script will still fall back to a simple ``urlopen`` on
  platforms that do not have these tools.
* `Issue #65 <https://bitbucket.org/pypa/setuptools/issue/65>`_: Deprecated the ``Features`` functionality.
* `Issue #52 <https://bitbucket.org/pypa/setuptools/issue/52>`_: In ``VerifyingHTTPSConn``, handle a tunnelled (proxied)
  connection.

Backward-Incompatible Changes
=============================

This release includes a couple of backward-incompatible changes, but most if
not all users will find 1.0 a drop-in replacement for 0.9.

* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: Normalized API of environment marker support. Specifically,
  removed line number and filename from SyntaxErrors when returned from
  `pkg_resources.invalid_marker`. Any clients depending on the specific
  string representation of exceptions returned by that function may need to
  be updated to account for this change.
* `Issue #50 <https://bitbucket.org/pypa/setuptools/issue/50>`_: SyntaxErrors generated by `pkg_resources.invalid_marker` are
  normalized for cross-implementation consistency.
* Removed ``--ignore-conflicts-at-my-risk`` and ``--delete-conflicting``
  options to easy_install. These options have been deprecated since 0.6a11.

-----
0.9.8
-----

* `Issue #53 <https://bitbucket.org/pypa/setuptools/issue/53>`_: Fix NameErrors in `_vcs_split_rev_from_url`.

  upgrading over other releases of Setuptools.

-----
0.9.3
-----

* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix new ``AttributeError`` introduced in last fix.

-----
0.9.2
-----

* `Issue #42 <https://bitbucket.org/pypa/setuptools/issue/42>`_: Fix regression where blank checksums would trigger an
  ``AttributeError``.

-----
0.9.1
-----

* `Distribute #386 <https://bitbucket.org/tarek/distribute/issue/386>`_: Allow other positional and keyword arguments to os.open.
* Corrected dependency on certifi mis-referenced in 0.9.

---
0.9
---

* `package_index` now validates hashes other than MD5 in download links.

-----
0.7.7
-----

* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release (redo).
* `Issue #30 <https://bitbucket.org/pypa/setuptools/issue/30>`_: Added test for get_cache_path.

-----
0.7.6
-----

* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Repair AttributeError created in last release.

-----
0.7.5
-----

* `Issue #21 <https://bitbucket.org/pypa/setuptools/issue/21>`_: Restore Python 2.4 compatibility in ``test_easy_install``.
* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Merged additional warning from Distribute 0.6.46.
* Now honor the environment variable
  ``SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT`` in addition to the now
  deprecated ``DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT``.

-----
0.7.4
-----

* `Issue #20 <https://bitbucket.org/pypa/setuptools/issue/20>`_: Fix comparison of parsed SVN version on Python 3.

-----
0.7.3
-----

* `Issue #1 <https://bitbucket.org/pypa/setuptools/issue/1>`_: Disable installation of Windows-specific files on non-Windows systems.
* Use new sysconfig module with Python 2.7 or >=3.2.

-----
0.7.2
-----

* `Issue #14 <https://bitbucket.org/pypa/setuptools/issue/14>`_: Use markerlib when the `parser` module is not available.
* `Issue #10 <https://bitbucket.org/pypa/setuptools/issue/10>`_: ``ez_setup.py`` now uses HTTPS to download setuptools from PyPI.

-----
0.7.1
-----

* Fix NameError (`Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_) again - broken in bad merge.

---
0.7
---

* Merged Setuptools and Distribute. See docs/merge.txt for details.

Added several features that were slated for setuptools 0.6c12:

* Index URL now defaults to HTTPS.
* Added experimental environment marker support. Now clients may designate a
  PEP-426 environment marker for "extra" dependencies. Setuptools uses this
  feature in ``setup.py`` for optional SSL and certificate validation support
  on older platforms. Based on Distutils-SIG discussions, the syntax is
  somewhat tentative. There should probably be a PEP with a firmer spec before
  the feature should be considered suitable for use.
* Added support for SSL certificate validation when installing packages from
  an HTTPS service.

-----
0.7b4
-----

* `Issue #3 <https://bitbucket.org/pypa/setuptools/issue/3>`_: Fixed NameError in SSL support.

------
0.6.49
------

* Move warning check in ``get_cache_path`` to follow the directory creation
  to avoid errors when the cache path does not yet exist. Fixes the error
  reported in `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_.

------
0.6.48
------

* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
  0.6.46 (redo).

------
0.6.47
------

* Correct AttributeError in ``ResourceManager.get_cache_path`` introduced in
  0.6.46.

------
0.6.46
------

* `Distribute #375 <https://bitbucket.org/tarek/distribute/issue/375>`_: Issue a warning if the PYTHON_EGG_CACHE or otherwise
  customized egg cache location specifies a directory that's group- or
  world-writable.

------

0.6.41
------

* `Distribute #27 <https://bitbucket.org/tarek/distribute/issue/27>`_: Use public api for loading resources from zip files rather than

  Installer Detection Technology and thus undesirable UAC elevation described
  in `this Microsoft article
  <http://technet.microsoft.com/en-us/library/cc709628%28WS.10%29.aspx>`_.

------
0.6.36
------

  the ``__pycache__`` directory as a file, causing an error, apparently only
  under Windows. Easy_install now skips all directories when processing
  metadata scripts.

  such as numpy does. This change should address
  `virtualenv `#359 <https://bitbucket.org/pypa/setuptools/issue/359>`_ <https://github.com/pypa/virtualenv/issues/359>`_ as long
  as the system encoding is UTF-8 or the IO encoding is specified in the

  methods. Also had to updated how __path__ is handled for namespace packages
  to ensure that when a new egg distribution containing a namespace package is
  placed on sys.path, the entries in __path__ are found in the same order they
  would have been in had that egg been on the path when pkg_resources was
  first imported.

-----
0.6c9
-----

 * Fixed a missing files problem when using Windows source distributions on
   non-Windows platforms, due to distutils not handling manifest file line
   endings correctly.

 * Updated Pyrex support to work with Pyrex 0.9.6 and higher.

 * Minor changes for Jython compatibility, including skipping tests that can't
   work on Jython.

 * Fixed not installing eggs in ``install_requires`` if they were also used for
   ``setup_requires`` or ``tests_require``.

 * Fixed not fetching eggs in ``install_requires`` when running tests.

 * Allow ``ez_setup.use_setuptools()`` to upgrade existing setuptools
   installations when called from a standalone ``setup.py``.

 * Added a warning if a namespace package is declared, but its parent package
   is not also declared as a namespace.

 * Support Subversion 1.5

 * Removed use of deprecated ``md5`` module if ``hashlib`` is available

 * Fixed ``bdist_wininst upload`` trying to upload the ``.exe`` twice

 * Fixed ``bdist_egg`` putting a ``native_libs.txt`` in the source package's
   ``.egg-info``, when it should only be in the built egg's ``EGG-INFO``.

 * Ensure that _full_name is set on all shared libs before extensions are
   checked for shared lib usage.  (Fixes a bug in the experimental shared
   library build support.)

 * Fix to allow unpacked eggs containing native libraries to fail more
   gracefully under Google App Engine (with an ``ImportError`` loading the
   C-based module, instead of getting a ``NameError``).

-----
0.6c7
-----

 * Fixed ``distutils.filelist.findall()`` crashing on broken symlinks, and
   ``egg_info`` command failing on new, uncommitted SVN directories.

 * Fix import problems with nested namespace packages installed via
   ``--root`` or ``--single-version-externally-managed``, due to the
   parent package not having the child package as an attribute.

-----
0.6c6
-----

 * Added ``--egg-path`` option to ``develop`` command, allowing you to force
   ``.egg-link`` files to use relative paths (allowing them to be shared across
   platforms on a networked drive).

 * Fix not building binary RPMs correctly.

 * Fix "eggsecutables" (such as setuptools' own egg) only being runnable with
   bash-compatible shells.

 * Fix ``#!`` parsing problems in Windows ``.exe`` script wrappers, when there
   was whitespace inside a quoted argument or at the end of the ``#!`` line
   (a regression introduced in 0.6c4).

 * Fix ``test`` command possibly failing if an older version of the project
   being tested was installed on ``sys.path`` ahead of the test source
   directory.

 * Fix ``find_packages()`` treating ``ez_setup`` and directories with ``.`` in
   their names as packages.

-----
0.6c5
-----

 * Fix uploaded ``bdist_rpm`` packages being described as ``bdist_egg``
   packages under Python versions less than 2.5.

 * Fix uploaded ``bdist_wininst`` packages being described as suitable for
   "any" version by Python 2.5, even if a ``--target-version`` was specified.

-----
0.6c4
-----

 * Overhauled Windows script wrapping to support ``bdist_wininst`` better.
   Scripts installed with ``bdist_wininst`` will always use ``#!python.exe`` or
   ``#!pythonw.exe`` as the executable name (even when built on non-Windows
   platforms!), and the wrappers will look for the executable in the script's
   parent directory (which should find the right version of Python).

 * Fix ``upload`` command not uploading files built by ``bdist_rpm`` or
   ``bdist_wininst`` under Python 2.3 and 2.4.

 * Add support for "eggsecutable" headers: a ``#!/bin/sh`` script that is
   prepended to an ``.egg`` file to allow it to be run as a script on Unix-ish
   platforms.  (This is mainly so that setuptools itself can have a single-file
   installer on Unix, without doing multiple downloads, dealing with firewalls,
   etc.)

 * Fix problem with empty revision numbers in Subversion 1.4 ``entries`` files

 * Use cross-platform relative paths in ``easy-install.pth`` when doing
   ``develop`` and the source directory is a subdirectory of the installation
   target directory.

 * Fix a problem installing eggs with a system packaging tool if the project
   contained an implicit namespace package; for example if the ``setup()``
   listed a namespace package ``foo.bar`` without explicitly listing ``foo``
   as a namespace package.

-----
0.6c3
-----

 * Fixed breakages caused by Subversion 1.4's new "working copy" format

-----
0.6c2
-----

 * The ``ez_setup`` module displays the conflicting version of setuptools (and
   its installation location) when a script requests a version that's not
   available.

 * Running ``setup.py develop`` on a setuptools-using project will now install
   setuptools if needed, instead of only downloading the egg.

-----
0.6c1
-----

 * Fixed ``AttributeError`` when trying to download a ``setup_requires``
   dependency when a distribution lacks a ``dependency_links`` setting.

 * Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
   as to play better with packaging tools that complain about zero-length
   files.

 * Made ``setup.py develop`` respect the ``--no-deps`` option, which it
   previously was ignoring.

 * Support ``extra_path`` option to ``setup()`` when ``install`` is run in
   backward-compatibility mode.

 * Source distributions now always include a ``setup.cfg`` file that explicitly
   sets ``egg_info`` options such that they produce an identical version number
   to the source distribution's version number.  (Previously, the default
   version number could be different due to the use of ``--tag-date``, or if
   the version was overridden on the command line that built the source
   distribution.)

-----
0.6b4
-----

 * Fix ``register`` not obeying name/version set by ``egg_info`` command, if
   ``egg_info`` wasn't explicitly run first on the same command line.

 * Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
   command, to allow suppressing tags configured in ``setup.cfg``.

 * Fixed redundant warnings about missing ``README`` file(s); it should now
   appear only if you are actually a source distribution.

-----
0.6b3
-----

 * Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.

 * Allow ``.py`` files found by the ``include_package_data`` option to be
   automatically included.  Remove duplicate data file matches if both
   ``include_package_data`` and ``package_data`` are used to refer to the same
   files.

-----
0.6b1
-----

 * Strip ``module`` from the end of compiled extension modules when computing
   the name of a ``.py`` loader/wrapper.  (Python's import machinery ignores
   this suffix when searching for an extension module.)

------
0.6a11
------

 * Added ``test_loader`` keyword to support custom test loaders

 * Added ``setuptools.file_finders`` entry point group to allow implementing
   revision control plugins.

 * Added ``--identity`` option to ``upload`` command.

 * Added ``dependency_links`` to allow specifying URLs for ``--find-links``.

 * Enhanced test loader to scan packages as well as modules, and call
   ``additional_tests()`` if present to get non-unittest tests.

 * Support namespace packages in conjunction with system packagers, by omitting
   the installation of any ``__init__.py`` files for namespace packages, and
   adding a special ``.pth`` file to create a working package in
   ``sys.modules``.

 * Made ``--single-version-externally-managed`` automatic when ``--root`` is
   used, so that most system packagers won't require special support for
   setuptools.

 * Fixed ``setup_requires``, ``tests_require``, etc. not using ``setup.cfg`` or
   other configuration files for their option defaults when installing, and
   also made the install use ``--multi-version`` mode so that the project
   directory doesn't need to support .pth files.

 * ``MANIFEST.in`` is now forcibly closed when any errors occur while reading
   it.  Previously, the file could be left open and the actual error would be
   masked by problems trying to remove the open file on Windows systems.

------
0.6a10
------

 * Fixed the ``develop`` command ignoring ``--find-links``.

-----
0.6a9
-----

 * The ``sdist`` command no longer uses the traditional ``MANIFEST`` file to
   create source distributions.  ``MANIFEST.in`` is still read and processed,
   as are the standard defaults and pruning.  But the manifest is built inside
   the project's ``.egg-info`` directory as ``SOURCES.txt``, and it is rebuilt
   every time the ``egg_info`` command is run.

 * Added the ``include_package_data`` keyword to ``setup()``, allowing you to
   automatically include any package data listed in revision control or
   ``MANIFEST.in``

 * Added the ``exclude_package_data`` keyword to ``setup()``, allowing you to
   trim back files included via the ``package_data`` and
   ``include_package_data`` options.

 * Fixed ``--tag-svn-revision`` not working when run from a source
   distribution.

 * Added warning for namespace packages with missing ``declare_namespace()``

 * Added ``tests_require`` keyword to ``setup()``, so that e.g. packages
   requiring ``nose`` to run unit tests can make this dependency optional
   unless the ``test`` command is run.

 * Made all commands that use ``easy_install`` respect its configuration
   options, as this was causing some problems with ``setup.py install``.

 * Added an ``unpack_directory()`` driver to ``setuptools.archive_util``, so
   that you can process a directory tree through a processing filter as if it
   were a zipfile or tarfile.

 * Added an internal ``install_egg_info`` command to use as part of old-style
   ``install`` operations, that installs an ``.egg-info`` directory with the
   package.

 * Added a ``--single-version-externally-managed`` option to the ``install``
   command so that you can more easily wrap a "flat" egg in a system package.

 * Enhanced ``bdist_rpm`` so that it installs single-version eggs that
   don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
   since all RPMs are now built in a more backwards-compatible format.

 * Support full roundtrip translation of eggs to and from ``bdist_wininst``
   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
   egg in an .exe that will safely install it as an egg (i.e., with metadata
   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
   back into an ``.egg`` file or directory and install it as such.


-----
0.6a8
-----

 * Fixed some problems building extensions when Pyrex was installed, especially
   with Python 2.4 and/or packages using SWIG.

 * Made ``develop`` command accept all the same options as ``easy_install``,
   and use the ``easy_install`` command's configuration settings as defaults.

 * Made ``egg_info --tag-svn-revision`` fall back to extracting the revision
   number from ``PKG-INFO`` in case it is being run on a source distribution of
   a snapshot taken from a Subversion-based project.

 * Automatically detect ``.dll``, ``.so`` and ``.dylib`` files that are being
   installed as data, adding them to ``native_libs.txt`` automatically.

 * Fixed some problems with fresh checkouts of projects that don't include
   ``.egg-info/PKG-INFO`` under revision control and put the project's source
   code directly in the project directory.  If such a package had any
   requirements that get processed before the ``egg_info`` command can be run,
   the setup scripts would fail with a "Missing 'Version:' header and/or
   PKG-INFO file" error, because the egg runtime interpreted the unbuilt
   metadata in a directory on ``sys.path`` (i.e. the current directory) as
   being a corrupted egg.  Setuptools now monkeypatches the distribution
   metadata cache to pretend that the egg has valid version information, until
   it has a chance to make it actually be so (via the ``egg_info`` command).

-----
0.6a5
-----

 * Fixed missing gui/cli .exe files in distribution.  Fixed bugs in tests.

-----
0.6a3
-----

 * Added ``gui_scripts`` entry point group to allow installing GUI scripts
   on Windows and other platforms.  (The special handling is only for Windows;
   other platforms are treated the same as for ``console_scripts``.)

-----
0.6a2
-----

 * Added ``console_scripts`` entry point group to allow installing scripts
   without the need to create separate script files.  On Windows, console
   scripts get an ``.exe`` wrapper so you can just type their name.  On other
   platforms, the scripts are written without a file extension.

-----
0.6a1
-----

 * Added support for building "old-style" RPMs that don't install an egg for
   the target package, using a ``--no-egg`` option.

 * The ``build_ext`` command now works better when using the ``--inplace``
   option and multiple Python versions.  It now makes sure that all extensions
   match the current Python version, even if newer copies were built for a
   different Python version.

 * The ``upload`` command no longer attaches an extra ``.zip`` when uploading
   eggs, as PyPI now supports egg uploads without trickery.

 * The ``ez_setup`` script/module now displays a warning before downloading
   the setuptools egg, and attempts to check the downloaded egg against an
   internal MD5 checksum table.

 * Fixed the ``--tag-svn-revision`` option of ``egg_info`` not finding the
   latest revision number; it was using the revision number of the directory
   containing ``setup.py``, not the highest revision number in the project.

 * Added ``eager_resources`` setup argument

 * The ``sdist`` command now recognizes Subversion "deleted file" entries and
   does not include them in source distributions.

 * ``setuptools`` now embeds itself more thoroughly into the distutils, so that
   other distutils extensions (e.g. py2exe, py2app) will subclass setuptools'
   versions of things, rather than the native distutils ones.

 * Added ``entry_points`` and ``setup_requires`` arguments to ``setup()``;
   ``setup_requires`` allows you to automatically find and download packages
   that are needed in order to *build* your project (as opposed to running it).

 * ``setuptools`` now finds its commands, ``setup()`` argument validators, and
   metadata writers using entry points, so that they can be extended by
   third-party packages.  See `Creating distutils Extensions
   <http://pythonhosted.org/setuptools/setuptools.html#creating-distutils-extensions>`_
   for more details.

 * The vestigial ``depends`` command has been removed.  It was never finished
   or documented, and never would have worked without EasyInstall - which it
   pre-dated and was never compatible with.

------
0.5a12
------

 * The zip-safety scanner now checks for modules that might be used with
   ``python -m``, and marks them as unsafe for zipping, since Python 2.4 can't
   handle ``-m`` on zipped modules.

------
0.5a11
------

 * Fix breakage of the "develop" command that was caused by the addition of
   ``--always-unzip`` to the ``easy_install`` command.

-----
0.5a9
-----

 * Include ``svn:externals`` directories in source distributions as well as
   normal subversion-controlled files and directories.

 * Added ``exclude=patternlist`` option to ``setuptools.find_packages()``

 * Changed --tag-svn-revision to include an "r" in front of the revision number
   for better readability.

 * Added ability to build eggs without including source files (except for any
   scripts, of course), using the ``--exclude-source-files`` option to
   ``bdist_egg``.

 * ``setup.py install`` now automatically detects when an "unmanaged" package
   or module is going to be on ``sys.path`` ahead of a package being installed,
   thereby preventing the newer version from being imported.  If this occurs,
   a warning message is output to ``sys.stderr``, but installation proceeds
   anyway.  The warning message informs the user what files or directories
   need deleting, and advises them they can also use EasyInstall (with the
   ``--delete-conflicting`` option) to do it automatically.

 * The ``egg_info`` command now adds a ``top_level.txt`` file to the metadata
   directory that lists all top-level modules and packages in the distribution.
   This is used by the ``easy_install`` command to find possibly-conflicting
   "unmanaged" packages when installing the distribution.

 * Added ``zip_safe`` and ``namespace_packages`` arguments to ``setup()``.
   Added package analysis to determine zip-safety if the ``zip_safe`` flag
   is not given, and advise the author regarding what code might need changing.

 * Fixed the swapped ``-d`` and ``-b`` options of ``bdist_egg``.

-----
0.5a8
-----

 * The "egg_info" command now always sets the distribution metadata to "safe"
   forms of the distribution name and version, so that distribution files will
   be generated with parseable names (i.e., ones that don't include '-' in the
   name or version).  Also, this means that if you use the various ``--tag``
   options of "egg_info", any distributions generated will use the tags in the
   version, not just egg distributions.

 * Added support for defining command aliases in distutils configuration files,
   under the "[aliases]" section.  To prevent recursion and to allow aliases to
   call the command of the same name, a given alias can be expanded only once
   per command-line invocation.  You can define new aliases with the "alias"
   command, either for the local, global, or per-user configuration.

 * Added "rotate" command to delete old distribution files, given a set of
   patterns to match and the number of files to keep.  (Keeps the most
   recently-modified distribution files matching each pattern.)

 * Added "saveopts" command that saves all command-line options for the current
   invocation to the local, global, or per-user configuration file.  Useful for
   setting defaults without having to hand-edit a configuration file.

 * Added a "setopt" command that sets a single option in a specified distutils
   configuration file.

-----
0.5a7
-----

 * Added "upload" support for egg and source distributions, including a bug
   fix for "upload" and a temporary workaround for lack of .egg support in
   PyPI.

-----
0.5a6
-----

 * Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it
   will include all files under revision control (CVS or Subversion) in the
   current directory, and it will regenerate the list every time you create a
   source distribution, not just when you tell it to.  This should make the
   default "do what you mean" more often than the distutils' default behavior
   did, while still retaining the old behavior in the presence of MANIFEST.in.

 * Fixed the "develop" command always updating .pth files, even if you
   specified ``-n`` or ``--dry-run``.

 * Slightly changed the format of the generated version when you use
   ``--tag-build`` on the "egg_info" command, so that you can make tagged
   revisions compare *lower* than the version specified in setup.py (e.g. by
   using ``--tag-build=dev``).

-----
0.5a5
-----

 * Added ``develop`` command to ``setuptools``-based packages.  This command
   installs an ``.egg-link`` pointing to the package's source directory, and
   script wrappers that ``execfile()`` the source versions of the package's
   scripts.  This lets you put your development checkout(s) on sys.path without
   having to actually install them.  (To uninstall the link, use
   use ``setup.py develop --uninstall``.)

 * Added ``egg_info`` command to ``setuptools``-based packages.  This command
   just creates or updates the "projectname.egg-info" directory, without
   building an egg.  (It's used by the ``bdist_egg``, ``test``, and ``develop``
   commands.)

 * Enhanced the ``test`` command so that it doesn't install the package, but
   instead builds any C extensions in-place, updates the ``.egg-info``
   metadata, adds the source directory to ``sys.path``, and runs the tests
   directly on the source.  This avoids an "unmanaged" installation of the
   package to ``site-packages`` or elsewhere.

 * Made ``easy_install`` a standard ``setuptools`` command, moving it from
   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
   that if you were importing or extending it, you must now change your imports
   accordingly.  ``easy_install.py`` is still installed as a script, but not as
   a module.

-----
0.5a4
-----

 * Setup scripts using setuptools can now list their dependencies directly in
   the setup.py file, without having to manually create a ``depends.txt`` file.
   The ``install_requires`` and ``extras_require`` arguments to ``setup()``
   are used to create a dependencies file automatically.  If you are manually
   creating ``depends.txt`` right now, please switch to using these setup
   arguments as soon as practical, because ``depends.txt`` support will be
   removed in the 0.6 release cycle.  For documentation on the new arguments,
   see the ``setuptools.dist.Distribution`` class.

 * Setup scripts using setuptools now always install using ``easy_install``
   internally, for ease of uninstallation and upgrading.

-----
0.5a1
-----

 * Added support for "self-installation" bootstrapping.  Packages can now
   include ``ez_setup.py`` in their source distribution, and add the following
   to their ``setup.py``, in order to automatically bootstrap installation of
   setuptools as part of their setup process::

    from ez_setup import use_setuptools
    use_setuptools()

    from setuptools import setup
    # etc...

-----
0.4a2
-----

 * Added ``ez_setup.py`` installer/bootstrap script to make initial setuptools
   installation easier, and to allow distributions using setuptools to avoid
   having to include setuptools in their source distribution.

 * All downloads are now managed by the ``PackageIndex`` class (which is now
   subclassable and replaceable), so that embedders can more easily override
   download logic, give download progress reports, etc.  The class has also
   been moved to the new ``setuptools.package_index`` module.

 * The ``Installer`` class no longer handles downloading, manages a temporary
   directory, or tracks the ``zip_ok`` option.  Downloading is now handled
   by ``PackageIndex``, and ``Installer`` has become an ``easy_install``
   command class based on ``setuptools.Command``.

 * There is a new ``setuptools.sandbox.run_setup()`` API to invoke a setup
   script in a directory sandbox, and a new ``setuptools.archive_util`` module
   with an ``unpack_archive()`` API.  These were split out of EasyInstall to
   allow reuse by other tools and applications.

 * ``setuptools.Command`` now supports reinitializing commands using keyword
   arguments to set/reset options.  Also, ``Command`` subclasses can now set
   their ``command_consumes_arguments`` attribute to ``True`` in order to
   receive an ``args`` option containing the rest of the command line.

-----
0.3a2
-----

 * Added new options to ``bdist_egg`` to allow tagging the egg's version number
   with a subversion revision number, the current date, or an explicit tag
   value.  Run ``setup.py bdist_egg --help`` to get more information.

 * Misc. bug fixes

-----
0.3a1
-----

 * Initial release.
