PYTHON 3 SUPPORT
=================
-Current Python 3k support in SQLAlchemy is provided by a customized
-2to3 script which wraps Python's 2to3 tool.
-
-Installing Distribute
----------------------
-
-Distribute should be installed with the Python3 installation. The
-distribute bootloader is included.
-
-Running as a user with permission to modify the Python distribution,
-install Distribute:
-
- python3 distribute_setup.py
-
-
-Installing SQLAlchemy in Python 3
----------------------------------
-
-Once Distribute is installed, SQLAlchemy can be installed directly.
-The 2to3 process will kick in which takes several minutes:
-
- python3 setup.py install
-
-Converting Tests, Examples, Source to Python 3
-----------------------------------------------
-
-To convert all files in the source distribution, run
-SQLAlchemys "sa2to3.py" script, which monkeypatches a preprocessor
-onto the 2to3 tool:
-
- python3 sa2to3.py --no-diffs -w lib test examples
-
-The above will rewrite all files in-place in Python 3 format.
-
-Running Tests
--------------
-
-To run unit tests in Py3k, Nose 1.0 is required, or a development
-version of Nose that supports Python 3. The tests are run
-using ./sqla_nose.py as described in README.unittests.
-
-Current 3k Issues
------------------
-
-Current bugs and tickets related to Py3k are on the Py3k milestone in trac:
-
-http://www.sqlalchemy.org/trac/query?status=new&status=assigned&status=reopened&milestone=py3k
-
+As of SQLAlchemy 0.9, SQLAlchemy installs and runs with
+Python 3 directly, with no code changes.

-"""SQLAlchemy 2to3 tool.
-
-This tool monkeypatches a preprocessor onto
-lib2to3.refactor.RefactoringTool, so that conditional
-sections can replace non-fixable Python 2 code sections
-for the appropriate Python 3 version before 2to3 is run.
