-----

* Fix include dir copying on Windows (makes compiling possible).
* Include the main ``lib-tk`` in the path.
* Patch ``distutils.sysconfig``: ``get_python_inc`` and
``get_python_lib`` to point to the global locations.
* Install ``distutils.cfg`` before Setuptools, so that system
customizations of ``distutils.cfg`` won't effect the installation.
* Add ``bin/pythonX.Y`` to the virtualenv (in addition to
``bin/python``).
* Fixed an issue with Mac Framework Python builds, and absolute paths
(from Ronald Oussoren).

-----

* Improve ability to create a virtualenv from inside a virtualenv.
* Fix a little bug in ``bin/activate``.
* Actually get ``distutils.cfg`` to work reliably.

---

* Added ``lib-dynload`` and ``config`` to things that need to be
copied over in an environment.
* Copy over or symlink the ``include`` directory, so that you can
build packages that need the C headers.
* Include a ``distutils`` package, so you can locally update
``distutils.cfg`` (in ``lib/pythonX.Y/distutils/distutils.cfg``).
* Better avoid downloading Setuptools, and hitting PyPI on environment
creation.
* Fix a problem creating a ``lib64/`` directory.
* Should work on MacOSX Framework builds (the default Python
installations on Mac). Thanks to Ronald Oussoren.

-----

* Windows installs would sometimes give errors about ``sys.prefix`` that
were inaccurate.
* Slightly prettier output.

-----

* Added support for Windows.

-----

* Give a better warning if you are on an unsupported platform (Mac
Framework Pythons, and Windows).
* Give error about running while inside a workingenv.
* Give better error message about Python 2.3.
