+ *
+ * Usage:
+ * addrinfo-test [-t|-u|-R|-I] [-d|-s|-r] [-p port] [-P] [hostname]
+ *
+ * When invoked with no arguments, NULL is used for the node name,
+ * which (at least with a non-null "port") means a socket address
+ * is desired that can be used with connect() or bind() (depending
+ * on whether "-P" is given).
