SET
 The ``ubla set`` command enables or disables uniform

SET EXAMPLES
 Configure your buckets to use uniform bucket-level access:

gsutil ubla set off gs://redbucket gs://bluebucket
"""

GET
 The ``ubla get`` command shows whether uniform bucket-level access is enabled

 Check if your buckets are using uniform bucket-level access:
