-<B>DESCRIPTION</B>
-  The stat command will output details about the specified object URLs.
-  It is similar to running:
-
-    gsutil ls -L gs://some-bucket/some-object
-
-  but is more efficient because it avoids performing bucket listings and gets
-  the minimum necessary amount of object metadata. Moreover, because it avoids
-  performing bucket listings (which are eventually consistent) the gsutil stat
-  command provides a strongly consistent way to check for the existence (and
-  read the metadata) of an object.
-
-  The gsutil stat command will, however, perform bucket listings if you specify
-  URLs using wildcards.
-
-  If run with the gsutil -q option nothing will be printed, e.g.:
-
-    gsutil -q stat gs://some-bucket/some-object
-
-  This can be useful for writing scripts, because the exit status will be 0 for
-  an existing object and 1 for a non-existent object.
-
-  Note: Unlike the gsutil ls command, the stat command does not support
-  operations on sub-directories. For example, if you run the command:
-
-    gsutil -q stat gs://some-bucket/some-subdir/
-
-  gsutil will look for information about an object called "some-subdir/" (with a
-  trailing slash) inside the bucket "some-bucket", as opposed to operating on
-  objects nested under gs://some-bucket/some-subdir/. Unless you actually have
-  an object with that name, the operation will fail. However, you can use the
-  stat command on objects within subdirectories. For example, this command will
-  work as expected:
-
-    gsutil -q stat gs://some-bucket/some-subdir/file.txt
