			These options were used to implement “setup.py --name”, “setup.py --version”, etc. which are now handled by the pysetup metadata action or direct parsing of the setup.cfg file. As a side effect, the Distribution class no longer accepts a 'url' key in its *attrs* argument: it has to be 'home-page' to be recognized as a valid metadata field and passed down to the dist.metadata object. I cleaned up some comments, docstrings and code along the way.
