Import hooks; when installed (with the install()) function, these hooks
Import hooks; when installed with the install() function, these hooks
allow importing .pyx files as if they were Python modules.
If you want the hook installed every time you run Python
you can add it to your Python version by adding these lines to
sitecustomize.py (which you can create from scratch in site-packages
if it doesn't exist there are somewhere else on your python path)
if it doesn't exist there or somewhere else on your python path)::

For instance on the Mac with a non-system Python 2.3, you could create
sitecustomize.py with only those two lines at
/usr/local/lib/python2.3/site-packages/sitecustomize.py .
Running this module as a top-level script will run a test and then print
the documentation.
This code was modeled on Quixote's ptl_import.
This code is based on the Py2.3+ import protocol as described in PEP 302.
