        !            11: .SH SYNOPSIS
        !            12: .B /etc/fingerd
        !            13: .SH DESCRIPTION
        !            14: .I Fingerd
        !            15: is a simple protocol based on RFC742 that provides an interface to the
        !            16: Name and Finger programs at several network sites.
        !            17: The program is supposed to return a friendly,
        !            18: human-oriented status report on either the system at the moment
        !            19: or a particular person in depth.
        !            20: There is no required format and the
        !            21: protocol consists mostly of specifying a single ``command line''.
        !            22: .PP
        !            23: .I Fingerd
        !            24: listens for TCP requests at port 79.
        !            25: Once connected it reads a single command line
        !            26: terminated by a <CRLF> which is passed to
        !            27: .IR finger (1).
        !            28: .I Fingerd
        !            29: closes its connections as soon as the output is finished.
        !            30: .PP
        !            31: If the line is null (i.e. just a <CRLF> is sent) then 
        !            32: .I finger
        !            33: returns a ``default'' report that lists all people logged into
        !            34: the system at that moment.
        !            35: .PP
        !            36: If a user name is specified (e.g. eric<CRLF>) then the
        !            37: response lists more extended information for only that particular user,
        !            38: whether logged in or not.
        !            39: Allowable ``names'' in the command line include both ``login names''
        !            40: and ``user names''.
        !            41: If a name is ambiguous, all possible derivations are returned.

        !            43: finger(1)
        !            44: .SH BUGS
        !            45: Connecting directly to the server from a TIP
        !            46: or an equally narrow-minded TELNET-protocol user program can result
        !            47: in meaningless attempts at option negotiation being sent to the
        !            48: server, which will foul up the command line interpretation.
        !            49: .I Fingerd
        !            50: should be taught to filter out IAC's and perhaps even respond
        !            51: negatively (IAC WON'T) to all option commands received.
