t | j dd S )a Whether to use the ``importlib.metadata`` or ``pkg_resources`` backend.
By default, pip uses ``importlib.metadata`` on Python 3.11+, and
``pkg_resources`` otherwise. Up to Python 3.13, 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, for Python <3.14.
* On Python 3.11, 3.12 and 3.13, 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*).
On Python 3.14+, the ``pkg_resources`` backend cannot be used.
