+ * In general to call RTAS use rtas_token("string") to lookup
+ * an RTAS token for the given string (e.g. "event-scan").
+ * To actually perform the call use
+ *    ret = rtas_call(token, n_in, n_out, ...)
+ * Where n_in is the number of input parameters and
+ *       n_out is the number of output parameters
+ *
+ * If the "string" is invalid on this system, RTAS_UNKOWN_SERVICE
+ * will be returned as a token.  rtas_call() does look for this
+ * token and error out gracefully so rtas_call(rtas_token("str"), ...)
+ * may be safely used for one-shot calls to RTAS.
