+ * Configuration
+ *
+ * All configuration management messaging involves sending a request message
+ * to the TIPC configuration service on a node, which sends a reply message
+ * back.  (In the future multi-message replies may be supported.)
+ *
+ * Both request and reply messages consist of a transport header and payload.
+ * The transport header contains info about the desired operation;
+ * the payload consists of zero or more type/length/value (TLV) items
+ * which specify parameters or results for the operation.
+ *
+ * For many operations, the request and reply messages have a fixed number
+ * of TLVs (usually zero or one); however, some reply messages may return
+ * a variable number of TLVs.  A failed request is denoted by the presence
+ * of an "error string" TLV in the reply message instead of the TLV(s) the
+ * reply should contain if the request succeeds.
