This version of ExtensionClass uses Python distutils for installation.
It requires Python version 1.5.2 or higher.  To build, test, and
install, do the following:

The build directory is created setup.py during the build.  The exact
name of the build subdirectory depends on the platform you are using
and the version of Python.
