-
-<B>DESCRIPTION</B>
-  The gsutil mv command allows you to move data between your local file
-  system and the cloud, move data within the cloud, and move data between
-  cloud storage providers. For example, to move all objects from a
-  bucket to a local directory you could use:
-
-    gsutil mv gs://my_bucket dir
-
-  Similarly, to move all objects from a local directory to a bucket you could
-  use:
-
-    gsutil mv ./dir gs://my_bucket
-
-
-<B>RENAMING BUCKET SUBDIRECTORIES</B>
-  You can use the gsutil mv command to rename subdirectories. For example,
-  the command:
-
-    gsutil mv gs://my_bucket/olddir gs://my_bucket/newdir
-
-  would rename all objects and subdirectories under gs://my_bucket/olddir to be
-  under gs://my_bucket/newdir, otherwise preserving the subdirectory structure.
-
-  If you do a rename as specified above and you want to preserve ACLs, you
-  should use the -p option (see OPTIONS).
-
-  Note that when using mv to rename bucket subdirectories you cannot specify
-  the source URL using wildcards. You need to spell out the complete name:
-
-    gsutil mv gs://my_bucket/olddir gs://my_bucket/newdir
-
-  If you have a large number of files to move you might want to use the
-  gsutil -m option, to perform a multi-threaded/multi-processing move:
-
-    gsutil -m mv gs://my_bucket/olddir gs://my_bucket/newdir
-
-
-<B>NON-ATOMIC OPERATION</B>
-  Unlike the case with many file systems, the gsutil mv command does not
-  perform a single atomic operation. Rather, it performs a copy from source
-  to destination followed by removing the source for each object.
-
-
-<B>OPTIONS</B>
-  All options that are available for the gsutil cp command are also available
-  for the gsutil mv command (except for the -R flag, which is implied by the
-  gsutil mv command). Please see the OPTIONS sections of "gsutil help cp"
-  for more information.
