2 PEP 314: Metadata for Python Software Packages v1.1

Some simple dependency support was added to Distutils. The setup() function now has requires,provides, and obsoletes. When you build a source distribution using the sdist command, the dependency information will be recorded in the PKG-INFO file.

Another new keyword is download_url, which should be set to a URL for the package's source code. This means it's now possible to look up an entry in the package index, determine the dependencies for a package, and download the required packages.
