The setuptools.package_index.PackageIndex class knows about all 
discoverable versions.  However, this doesn't extend to versions that have 
been hidden by the package author.  To have more than one discoverable 
version at the PyPI level, the author has to have made them visible in the 
admin interface.

But, whichever ones *are* visible can be discovered by the PackageIndex 
class, along with any that are linked from the Home Page or Download URLs, 
or are linked on the package's PyPI page.

More precisely, PackageIndex doesn't track versions; it tracks available 
*distributions*, which may include source distributions, SVN checkouts, 
eggs, .exe's, etc.  But each distribution object carries version info 
determined from its filename.
