        !            10:      RRllooggiinn starts a terminal session on a remote host _h_o_s_t.
        !            11: 
        !            12:      RRllooggiinn first attempts to use the Kerberos authorization mechanism,
        !            13:      described below.  If the remote host does not supporting Kerberos the
        !            14:      standard Berkeley _r_h_o_s_t_s authorization mechanism is used.     The options
        !            15:      are as follows:
        !            16: 
        !            17:      --88        The --88 option allows an eight-bit input data path at all times;
        !            18:               otherwise parity bits are stripped except when the remote
        !            19:               side's stop and start characters are other than ^S/^Q.  Eight-
        !            20:               bit mode is the default.
        !            21: 
        !            22:      --KK        The --KK option turns off all Kerberos authentication.
        !            23: 
        !            24:      --LL        The --LL option allows the rlogin session to be run in ``litout''
        !            25:               (see tty(4)) mode.
        !            26: 
        !            27:      --dd        The --dd option turns on socket debugging (see setsockopt(2)) on
        !            28:               the TCP sockets used for communication with the remote host.
        !            29: 
        !            30:      --ee        By default, the tilde (``~'') character is the escape charac-
        !            31:               ter.  The --ee option allows specification of a different escape
        !            32:               character.
        !            33: 
        !            34:      --kk        The option requests rlogin to obtain tickets for the remote
        !            35:               host in realm _r_e_a_l_m instead of the remote host's realm as
        !            36:               determined by krb_realmofhost(3).
        !            37: 
        !            38:      --xx        The --xx option turns on DES encryption for all data passed via
        !            39:               the rlogin session.  This may impact response time and CPU
        !            40:               utilization, but provides increased security.
        !            41: 
        !            42:      A line of the form ``~.'' disconnects from the remote host, where ``~''
        !            43:      is the escape character.  Similarly, the line ``~^Z'' will suspend the
        !            44:      rrllooggiinn session.  Substitution of the delayed-suspend character (normally
        !            45:      ^Y) for the suspend character suspends the send portion of the rlogin,
        !            46:      but allows output from the remote system.
        !            47: 
        !            48:      All echoing takes place at the remote site, so that (except for delays)
        !            49:      the rrllooggiinn is transparent.  Flow control via ^S/^Q and flushing of input
        !            50:      and output on interrupts are handled properly.
        !            51:

        !            53:      Each user may have a private authorization list in the file ._k_l_o_g_i_n in
        !            54:      their home directory.  Each line in this file should contain a Kerberos
        !            55:      principal name of the form _p_r_i_n_c_i_p_a_l._i_n_s_t_a_n_c_e@_r_e_a_l_m.  If the originating
        !            56:      user is authenticated to one of the principals named in ._k_l_o_g_i_n, access
        !            57:      is granted to the account.  The principal _a_c_c_o_u_n_t_n_a_m_e.@_l_o_c_a_l_r_e_a_l_m is
        !            58:      granted access if there is no ._k_l_o_g_i_n file.  Otherwise a login and pass-
        !            59:      word will be prompted for on the remote machine as in login(1).  To avoid
        !            60:      certain security problems, the ._k_l_o_g_i_n file must be owned by the remote
        !            61:      user.
        !            62: 
        !            63:      If Kerberos authentication fails, a warning message is printed and the
        !            64:      standard Berkeley _r_l_o_g_i_n is used instead.
        !            65: 
        !            66: EENNVVIIRROONNMMEENNTT
        !            67:      The following environment variable is utilized by rrllooggiinn:
        !            68:      TERM      to find user's terminal type.
