                     14: .I Talkd
                     15: is the server that notifies a user that somebody else wants to
                     16: initiate a conversation.
                     17: It acts a repository of invitations, responding to requests
                     18: by clients wishing to rendezvous to hold a conversation.
                     19: In normal operation, a client, the caller,
                     20: initiates a rendezvous by sending a CTL_MSG to the server of
                     21: type LOOK_UP (see
                     22: .RI < protocols/talkd.h >).
                     23: This causes the server to search its invitation
                     24: tables to check if an invitation currently exists for the caller
                     25: (to speak to the callee specified in the message).
                     26: If the lookup fails,
                     27: the caller then sends an ANNOUNCE message causing the server to
                     28: broadcast an announcement on the callee's login ports requesting contact.
                     29: When the callee responds, the local server uses the
                     30: recorded invitation to respond with the appropriate rendezvous
                     31: address and the caller and callee client programs establish a
                     32: stream connection through which the conversation takes place.
