+
+
+<B>DESCRIPTION</B>
+  The Versioning Configuration feature enables you to configure a Google Cloud
+  Storage bucket to keep old versions of objects.
+
+  The gsutil getversioning command gets the versioning configuration for a
+  bucket, and displays an XML representation of the configuration.
+
+  In Google Cloud Storage, this would look like:
+
+  <?xml version="1.0" ?>
+  <VersioningConfiguration>
+    <Status>
+      Enabled
+    </Status>
+  </VersioningConfiguration>
