    The following attributes are available:
 
-   *pointer_bits* is the width of pointers in bits, as an integer, equivalent
-   to ``8 * sizeof(void *)``, i.e. usually ``32`` or ``64``.
-
-   *free_threaded* is a boolean indicating whether the interpreter supports
-   running in free-threaded mode (i.e. with the GIL disabled).
-   This reflects the presence of the :option:`--disable-gil` configure option,
-   or the setting of the ``DisableGil`` property on Windows, respectively.
-
-   *debug* is a boolean indicating whether the interpreter was built in
-   :ref:`debug mode <debug-build>`.
-   This reflects the presence of the :option:`--with-pydebug` configure option,
-   or the ``Debug`` configuration on Windows, respectively.
-
-   *byteorder* is a string indicating the native byte order, either ``'big'``
-   or ``'little'``.
-   This is the same as the :data:`sys.byteorder` attribute.
