+This package provides a collection of standard resource classes
+which are expected to be available in any OpenStack deployment.
+
+There also exists a concept of custom resource classes. These
+are countable types that are custom to a particular environment.
+The OpenStack placement API provides a way to create these. A
+custom resource class always begins with a "CUSTOM_" prefix.
