title: How do I disable "missing docstring" warnings at a file-level in Pylint?
body: <p>Pylint throws errors that some of the files are missing docstrings. I try and add docstrings to each class, method and function, but it seems that Pylint also checks that files should have a docstring at the beginning of them. Can I disable this somehow?</p>
  <p>I would like to be notified of a docstring is missing inside a class, function or method, but it shouldn't be mandatory for a file to have a docstring.</p>
  <p>(Is there a term for the legal jargon often found at the beginning of a proprietary source file? Any examples? I don't know whether it is a okay to post such a trivial question separately.)</p>
