    By default, pip uses ``importlib.metadata`` on Python 3.11+, and
    ``pkg_resourcess`` otherwise. This can be overridden by a couple of ways:

    * If environment variable ``_PIP_USE_IMPORTLIB_METADATA`` is set, it
      dictates whether ``importlib.metadata`` is used, regardless of Python
      version.
    * On Python 3.11+, Python distributors can patch ``importlib.metadata``
      to add a global constant ``_PIP_USE_IMPORTLIB_METADATA = False``. This
      makes pip use ``pkg_resources`` (unless the user set the aforementioned
      environment variable to *True*).
