-<B>SYNOPSIS</B>
-  gsutil cat [-h] uri...
-
-
-<B>DESCRIPTION</B>
-  The cat command outputs the contents of one or more URIs to stdout.
-  It is equivalent to doing:
-
-    gsutil cp uri... -
-
-  (The final '-' causes gsutil to stream the output to stdout.)
-
-
-<B>OPTIONS</B>
-  -h          Prints short header for each object. For example:
-                gsutil cat -h gs://bucket/meeting_notes/2012_Feb/*.txt
