 To actually use the OpenMP support, you need to tell the C or C++ compiler to
-enable OpenMP.  For gcc this can be done as follows in a setup.py::
-
-    from distutils.core import setup
-    from distutils.extension import Extension
-    from Cython.Build import cythonize
-
-    ext_modules = [
-        Extension(
-            "hello",
-            ["hello.pyx"],
-            extra_compile_args=['-fopenmp'],
-            extra_link_args=['-fopenmp'],
-        )
-    ]
-
-    setup(
-        name='hello-parallel-world',
-        ext_modules=cythonize(ext_modules),
-    )
+enable OpenMP.  For gcc this can be done as follows in a setup.py:

 For Microsoft Visual C++ compiler, use ``'/openmp'`` instead of ``'-fopenmp'``.
