25    Return a dictionary suitable for use in ``package_data``
26    in a distutils ``setup.py`` file.
27
28    The dictionary looks like::

32    Where ``files`` is a list of all the files in that package that
33    don't match anything in ``exclude``.
34
35    If ``only_in_packages`` is true, then top-level directories that
36    are not packages won't be included (but directories under packages
37    will).
38
39    Directories matching any pattern in ``exclude_directories`` will
40    be ignored; by default directories with leading ``.``, ``CVS``,
41    and ``_darcs`` will be ignored.
42
43    If ``show_ignored`` is true, then all the files that aren't
44    included in package data are shown on stderr (for debugging
45    purposes).
46
47    Note patterns use wildcards, or can be exact paths (including
48    leading ``./``), and all searching is case-insensitive.
