+ * @class Manager
+ *
+ * @brief This class provides the ability to add org.openbmc.Associations
+ *        interfaces on inventory D-Bus objects, based on a definition in a
+ *        JSON file.
+ *
+ *        The purpose for this is to be able to associate other D-Bus paths
+ *        with the inventory items they relate to.
+ *
+ *        For example, a card temperature sensor D-Bus object can be associated
+ *        with the D-Bus object for that card's inventory entry so that some
+ *        code can tie them together.
