-<B>DESCRIPTION</B>
-  The hash command calculates hashes on a local file that can be used to compare
-  with gsutil ls -L output. If a specific hash option is not provided, this
-  command calculates all gsutil-supported hashes for the file.
-
-  Note that gsutil automatically performs hash validation when uploading or
-  downloading files, so this command is only needed if you want to write a
-  script that separately checks the hash for some reason.
-
-  If you calculate a CRC32c hash for the file without a precompiled crcmod
-  installation, hashing will be very slow. See "gsutil help crcmod" for details.
-
-<B>OPTIONS</B>
-  -c          Calculate a CRC32c hash for the file.
-
-  -h          Output hashes in hex format. By default, gsutil uses base64.
-
-  -m          Calculate a MD5 hash for the file.
