Setuptools

======

* Fix 2 errors with Jython 2.5.
* Fix 1 failure with Jython 2.5 and 2.7.
* Disable workaround for Jython scripts on Linux systems.
* Distribute 336: ``setup.py`` no longer masks failure exit code when tests fail.
* Fix issue in pkg_resources where try/except around a platform-dependent
import would trigger hook load failures on Mercurial. See pull request 32
for details.
* Distribute 341: Fix a ResourceWarning.

======

* Fix test suite with Python 2.6.
* Fix some DeprecationWarnings and ResourceWarnings.
* Distribute 335: Backed out ``setup_requires`` superseding installed requirements
until regression can be addressed.

======

* Distribute 303: Make sure the manifest only ever contains UTF-8 in Python 3.
* Distribute 329: Properly close files created by tests for compatibility with
Jython.
* Work around Jython 1980 and Jython 1981.
* Distribute 334: Provide workaround for packages that reference ``sys.__stdout__``
such as numpy does. This change should address pypa/virtualenv359 as long
as the system encoding is UTF-8 or the IO encoding is specified in the
environment, i.e.::

PYTHONIOENCODING=utf8 pip install numpy

* Fix for encoding issue when installing from Windows executable on Python 3.
* Distribute 323: Allow ``setup_requires`` requirements to supersede installed
requirements. Added some new keyword arguments to existing pkg_resources
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.

======

* Distribute 328: Clean up temporary directories in distribute_setup.py.
* Fix fatal bug in distribute_setup.py.

======

* BB Pull Request 14: Honor file permissions in zip files.
* Distribute 327: Merged pull request 24 to fix a dependency problem with pip.
* Merged pull request 23 to fix pypa/virtualenv301.
* If Sphinx is installed, the ``upload_docs`` command now runs ``build_sphinx``
to produce uploadable documentation.
* Distribute 326: ``upload_docs`` provided mangled auth credentials under Python 3.
* Distribute 320: Fix check for "creatable" in distribute_setup.py.
* Distribute 305: Remove a warning that was triggered during normal operations.
* Distribute 311: Print metadata in UTF-8 independent of platform.
* Distribute 303: Read manifest file with UTF-8 encoding under Python 3.
* Distribute 301: Allow to run tests of namespace packages when using 2to3.
* Distribute 304: Prevent import loop in site.py under Python 3.3.
* Distribute 283: Re-enable scanning of ``*.pyc`` / ``*.pyo`` files on Python 3.3.
* Distribute 299: The develop command didn't work on Python 3, when using 2to3,
as the egg link would go to the Python 2 source. Linking to the 2to3'd code
in build/lib makes it work, although you will have to rebuild the module
before testing it.
* Distribute 306: Even if 2to3 is used, we build in-place under Python 2.
* Distribute 307: Prints the full path when .svn/entries is broken.
* Distribute 313: Support for sdist subcommands (Python 2.7)
* Distribute 314: test_local_index() would fail an OS X.
* Distribute 310: Non-ascii characters in a namespace __init__.py causes errors.
* Distribute 218: Improved documentation on behavior of ``package_data`` and
``include_package_data``. Files indicated by ``package_data`` are now included
in the manifest.
* ``distribute_setup.py`` now allows a ``--download-base`` argument for retrieving
distribute from a specified location.

======

* Distribute 294: setup.py can now be invoked from any directory.
* Scripts are now installed honoring the umask.
* Added support for .dist-info directories.
* Distribute 283: Fix and disable scanning of ``*.pyc`` / ``*.pyo`` files on
Python 3.3.
