      # compare lower than any numeric version number, and is therefore unlikely
      # to match a request for it.  It's still a potential problem, though, and
      # in the long run PyPI and the distutils should go for "safe" names and
      # versions in distribution archive names (sdist and bdist).

      Note: if `location` is a filesystem filename, you should call
      ``pkg_resources.normalize_path()`` on it before passing it to this
      routine!
