That's an unrelated feature of setuptools, providing a way to
"install" multiple versions of a package and select which version you
want at runtime. It does this by sys.path manipulation, I believe.

It's a good example of the sort of orthogonal feature which makes
setuptools such an issue. It's a genuinely useful feature to some
people, but it's unrelated to packaging and installation, so people
buy into a packaging solution (eggs) for the non-packaging benefits
they provide.
