+Connect to

+and read packets as the become available. The packets are discarded,
+though if stdout is a terminal, a simple spinning-baton animation is
+updated once for each group of packets. If you are flooding one end of
+a TrIPE connection, it's advisable to attach a sink to the other:
+otherwise the destination

+will attempt to consume all available memory, storing incoming packets
