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