+<B>SYNOPSIS</B>
+  gsutil mb [-c storage_class] [-l location] [-p proj_id] uri...
+
+
+<B>DESCRIPTION</B>
+  The mb command creates a new bucket. Google Cloud Storage has a single
+  namespace, so you will not be allowed to create a bucket with a name already
+  in use by another user. You can, however, carve out parts of the bucket name
+  space corresponding to your company's domain name (see "gsutil help naming").
+
+  If you don't specify a project ID using the -p option, the bucket
+  will be created using the default project ID specified in your gsutil
+  configuration file (see "gsutil help config"). For more details about
+  projects see "gsutil help projects".
+
+  The -c and -l options specify the storage class and location, respectively,
+  for the bucket. Once a bucket is created in a given location and with a
+  given storage class, it cannot be moved to a different location, and the
+  storage class cannot be changed. Instead, you would need to create a new
+  bucket and move the data over and then delete the original bucket.
+
+
+<B>BUCKET STORAGE CLASSES</B>
+  If you don't specify a -c option, the bucket will be created with the default
+  (standard) storage class.
+
+  If you specify -c DURABLE_REDUCED_AVAILABILITY (or -c DRA), it causes the data
+  stored in the bucket to use durable reduced availability storage. Buckets
+  created with this storage class have lower availability than standard storage
+  class buckets, but durability equal to that of buckets created with standard
+  storage class. This option allows users to reduce costs for data for which
+  lower availability is acceptable. Durable Reduced Availability storage would
+  not be appropriate for "hot" objects (i.e., objects being accessed frequently)
+  or for interactive workloads; however, it might be appropriate for other types
+  of applications. See the online documentation for pricing and SLA details.
+
+
+<B>BUCKET LOCATIONS</B>
+  If you don't specify a -l option, the bucket will be created in the default
+  location (US). Otherwise, you can specify one of the available locations:
+  US (United States) or EU (Europe).
+
+
+<B>OPTIONS</B>
+  -c storage_class  Can be DRA (or DURABLE_REDUCED_AVAILABILITY) or S (or
+                    STANDARD). Default is STANDARD.
+
+  -l location       Can be US or EU. Default is US. Locations are case
+                    insensitive.
+
+  -p proj_id        Specifies the project ID under which to create the bucket.
