Setuptools

=====

* 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).

* Update for changed SourceForge mirror format

* Fixed not installing dependencies for some packages fetched via Subversion

* Fixed dependency installation with ``--always-copy`` not using the same
dependency resolution procedure as other operations.

* Fixed not fully removing temporary directories on Windows, if a Subversion
checkout left read-only files behind

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

=====

* Fixed not being able to install Windows script wrappers using Python 2.3

=====

* Added support for "traditional" PYTHONPATH-based non-root installation, and
also the convenient ``virtual-python.py`` script, based on a contribution
by Ian Bicking. The setuptools egg now contains a hacked ``site`` module
that makes the PYTHONPATH-based approach work with .pth files, so that you
can get the full EasyInstall feature set on such installations.

* Added ``--no-deps`` and ``--allow-hosts`` options.

* Improved Windows ``.exe`` script wrappers so that the script can have the
same name as a module without confusing Python.

* Changed dependency processing so that it's breadth-first, allowing a
depender's preferences to override those of a dependee, to prevent conflicts
when a lower version is acceptable to the dependee, but not the depender.
Also, ensure that currently installed/selected packages aren't given
precedence over ones desired by a package being installed, which could
cause conflict errors.

=====

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

=====

* 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``.)

* Improved error message when trying to use old ways of running
``easy_install``. Removed the ability to run via ``python -m`` or by
running ``easy_install.py``; ``easy_install`` is the command to run on all
supported platforms.

* Improved wrapper script generation and runtime initialization so that a
VersionConflict doesn't occur if you later install a competing version of a
needed package as the default version of that package.

* Fixed a problem parsing version numbers in ``egg=`` links.

=====

* 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.

* EasyInstall can now install "console_scripts" defined by packages that use
``setuptools`` and define appropriate entry points. On Windows, console
scripts get an ``.exe`` wrapper so you can just type their name. On other
platforms, the scripts are installed without a file extension.

* Using ``python -m easy_install`` or running ``easy_install.py`` is now
DEPRECATED, since an ``easy_install`` wrapper is now available on all
platforms.
