+When you run a Python module with

+python fibo.py <arguments>
+\end{verbatim}
+
+the code in the module will be executed, just as if you imported it, but
+with the \code{__name__} set to \code{"__main__"}.  That means that by

+    fib(int(sys.argv[1]))

+
+you can make the file usable as a script as well as an importable module,

+executed as the ``main'' file:
+
+\begin{verbatim}
+$ python fibo.py 50

+\end{verbatim}
+
+If the module is imported, the code is not run:
+
+\begin{verbatim}
+>>> import fibo
+>>>
+\end{verbatim}
+
+This is often used either to provide a convenient user interface to a
+module, or for testing purposes (running the module as a script executes
+a test suite).
