distutils.setup_keywords

distutils.setup_keywords entry points are used by setuptools to add new keyword arguments to the setuptools.setup() function. If a project defines a distutils.setup_keywords entry point named foo that points to a function, then once the project is installed, setuptools.setup() will accept a keyword argument named foo and will use the given function to validate the argument before setting foo on the Distribution object. See the setuptools documentation for more information.
