+Documentation Testing
+=====================
+
+One of the most useful features of Python is one of its standard
+library modules.  The `doctest`_ module allows you to test
+interactive interpreter excerpts embedded either in the docstrings of
+your Python code or separate files to verify their correctness.  It's
+an excellent way to turn your documentation into your unit tests, and
+it's also how the document you're reading right now is tested for
+accuracy.
