Here is something I want to talk about::

    def my_fn(foo, bar=True):
        """A really useful function.

        Returns None
        """


This is inline ``if __name__ == '__main__':``


I really like the :mod:`threading` module which has the
:class:`threading.Thread` class.

Here is a link :func:`time.time`.

Typical result

A paragraph containing only two colons 
indicates that the following indented 
or quoted text is a literal block. 

:: 

  Whitespace, newlines, blank lines, and 
  all kinds of markup (like *this* or 
  \this) is preserved by literal blocks. 

  The paragraph containing only '::' 
  will be omitted from the result. 

The ``::`` may be tacked onto the very 
end of any paragraph. The ``::`` will be 
omitted if it is preceded by whitespace. 
The ``::`` will be converted to a single 
colon if preceded by text, like this:: 

  It's very convenient to use this form.
