interpreter and simply import it as if it was a regular python module::
>>> import helloworld
- "Hello World"
+ Hello World
Congratulations! You now know how to build a Cython extension. But So Far
this example doesn't really give a feeling why one would ever want to use Cython, so
:mod:`pyximport`: Cython Compilation the Easy Way
==================================================
+If your module doesn't require any extra libraries or other dependancies, then
+you can use the pyximport module by Paul Prescod to load .pyx files directly
+without having to write a :file:`setup.py` file.
+
+ >>> import pyximport; pyximport.install()
+ >>> import helloworld
+ Hello World
+
+This is shipped and installed with Cython.
Fibonacci Fun
