+<B>DESCRIPTION</B>
+  The rb command deletes new bucket. Buckets must be empty before you can delete
+  them.
+
+  Be certain you want to delete a bucket before you do so, as once it is
+  deleted the name becomes available and another user may create a bucket with
+  that name. (But see also "DOMAIN NAMED BUCKETS" under "gsutil help naming"
+  for help carving out parts of the bucket name space.)
