from distutils.core import setup, Extension

setup (name = "isect",
 version = "1.0",
 description = "Python interface to isect",
 author = "Thomas Gagne",
 author_email = "tgagne at ix.netcom.com",
 url = "http://home.netcom.com/~tgagne",
 py_modules = [ "CStructure", "IsdIO", "echo", "isdclient"],
 extensions = [Extension("isdio", ["isdio.c"])])

and the result:

$python setup.py sdist
