+ * @class HTTP_Client
+ *
+ * @brief HTTP_Client is intended to provide application API to
+ * classes that wish to do network i/o at a very
+ * high level of abstraction.
+ *
+ * This class provides the ability to retrieve data from
+ * the network, of specified length and offset, and potentially
+ * use any protocol "under the hood" to do so. It currently
+ * uses HTTP. See HTTP_Handler also.
