Tulip is the codename for my reference implementation of PEP 3156.

PEP 3156: http://www.python.org/dev/peps/pep-3156/

This requires Python 3.3 or later!

The actual code lives in the 'asyncio' subdirectory. Tests are in the 'tests' subdirectory.

To run tests:

• make test

To run coverage (coverage package is required):

• make coverage

On Windows, things are a little more complicated. Assume 'P' is your Python binary (for example C:Python33python.exe).

You must first build the _overlapped.pyd extension and have it placed in the asyncio directory, as follows:

C> P setup.py build_ext --inplace

If this complains about vcvars.bat, you probably don't have the required version of Visual Studio installed. Compiling extensions for Python 3.3 requires Microsoft Visual C++ 2010 (MSVC 10.0) of any edition; you can download Visual Studio Express 2010 for free from http://www.visualstudio.com/downloads (scroll down to Visual C++ 2010 Express).

Once you have built the _overlapped.pyd extension successfully you can run the tests as follows:

C> P runtests.py

And coverage as follows:

C> P runtests.py --coverage
