SET
 The ``pap set`` command configures public access prevention
 for Cloud Storage buckets. If you set a bucket to be
 ``inherited``, it uses public access prevention only if
 the bucket is subject to the `public access prevention
 <https://cloud.google.com/storage/docs/org-policy-constraints#public-access-prevention>`_
 organization policy constraint.

SET EXAMPLES
 Configure ``redbucket`` and ``bluebucket`` to use public
 access prevention:

gsutil pap set enforced gs://redbucket gs://bluebucket
"""

_GET_DESCRIPTION = """
GET
 The ``pap get`` command returns public access prevention
 values for the specified Cloud Storage buckets.

GET EXAMPLES
 Check if ``redbucket`` and ``bluebucket`` are using public
 access prevention:

gsutil pap get gs://redbucket gs://bluebucket
"""

 The ``pap`` command is used to retrieve or configure the
 `public access prevention
 <https://cloud.google.com/storage/docs/public-access-prevention>`_ setting of
 Cloud Storage buckets. This command has two sub-commands: ``get`` and ``set``.
