+/*
+ * This describes the protocol used by the talk server and clients.
+ *
+ * The talk server acts a repository of invitations, responding to
+ * requests by clients wishing to rendezvous for the purpose of
+ * holding a conversation.  In normal operation, a client, the caller,
+ * initiates a rendezvous by sending a CTL_MSG to the server of
+ * type LOOK_UP.  This causes the server to search its invitation
+ * tables to check if an invitation currently exists for the caller
+ * (to speak to the callee specified in the message).  If the lookup
+ * fails, the caller then sends an ANNOUNCE message causing the server
+ * to broadcast an announcement on the callee's login ports requesting
+ * contact.  When the callee responds, the local server uses the
+ * recorded invitation to respond with the appropriate rendezvous
+ * address and the caller and callee client programs establish a
+ * stream connection through which the conversation takes place.
