Validating NumpyDoc docstrings

To see the Restructured Text generated for an object, the numpydoc module can be called. For example, to do it for numpy.ndarray, use:

$ python -m numpydoc numpy.ndarray

This will validate that the docstring can be built.

For an exhaustive validation of the formatting of the docstring, use the --validate parameter. This will report the errors detected, such as incorrect capitalization, wrong order of the sections, and many other issues.
