+The ``cloud_staticfiles`` variable is to allow for the case where the
+Django static files are being collected to an external service, such
+as S3.  In that case, we don't want to be running ``collectstatic`` on
+every web instance, since they'll be getting in each other's way.
+This variable set to ``true`` causes the ``collectstatic`` task to be
+run only once.
