title: What to put in a python module docstring?
body: <p>Ok, so I've read both <a href="http://www.python.org/dev/peps/pep-0008/" rel="noreferrer">PEP 8</a> and <a href="http://www.python.org/dev/peps/pep-0257/" rel="noreferrer">PEP 257</a>, and I've written lots of docstrings for functions and classes, but I'm a little unsure about what should go in a module docstring.  I figured, at a minimum, it should document the functions and classes that the module exports, but I've also seen a few modules that list author names, copyright information, etc.  Does anyone have an example of how a good python docstring should be structured?</p>
