Here's a dirty little script that allows me to type:

  C:\> python pyx.py extension.pyx

and have pyrex produce an extension.c and an extension.pyd file
(assuming Pyrex is in sys.path of course). It's only been tested in
present form with single *.pyx files but I'm sure you can modify to do
what you want. Incidentally, I use Microsoft Visual C++ and winXP.

PS: Pyrex rocks.

ciao,

Sandy
