        !            12: DESCRIPTION
        !            13:      This program lets you play backgammon against  the  computer
        !            14:      or against a "friend".  All commands only are one letter, so
        !            15:      you don't need to type a carriage return, except at the  end
        !            16:      of  a move.  The program is mostly self documenting, so that
        !            17:      a question mark (?) will usually  get  some  help.   If  you
        !            18:      answer  `y' when the program asks if you want the rules, you
        !            19:      will get text explaining the rules of the game,  some  hints
        !            20:      on  strategy,  instruction  on how to use the program, and a
        !            21:      tutorial consisting of a practice game against the computer.
        !            22:      A  description  of how to use the program can be obtained by
        !            23:      answering `y' when it asks if you want instructions.
        !            24: 
        !            25:      The possible arguments for backgammon (most  are  unnecesary
        !            26:      but some are very convenient) consist of:
        !            27: 
        !            28:         _n       don't ask for rules or instructions
        !            29:         _r       player is red (implies n)
        !            30:         _w       player is white (implies n)
        !            31:         _b       two players, red and white (implies n)
        !            32:         _p_r      print the board before red's turn
        !            33:         _p_w      print the board before white's turn
        !            34:         _p_b      print the board before both player's turn
        !            35:         _t_t_e_r_m   terminal is type _t_e_r_m, uses /etc/termcap
        !            36:         _s_f_i_l_e   recover previously saved game from _f_i_l_e.  (This
        !            37:                 can also be done by executing the saved file,
        !            38:                 i.e., typing its name in as a command)
        !            39: 
        !            40:      Arguments may be optionally preceded by a `-'.  Several  ar-
        !            41:      guments  may  be concatenated together, but not after `s' or
        !            42:      `t' arguments, since they can be followed  by  an  arbitrary
        !            43:      string.   Any  unrecognized arguments are ignored.  An argu-
        !            44:      ment of a lone `-' gets a description of possible arguments.
        !            45: 
        !            46:      If _t_e_r_m has capabilities for  direct  cursor  movement  (see
        !            47:      ttycap(VII)),  _b_a_c_k_g_a_m_m_o_n "fixes" the board after each move,
        !            48:      so the board does not  need  to  be  reprinted,  unless  the
        !            49:      screen suffers some horrendous malady.  Also, any `p' option
        !            50:      will be ignored.  (The `t' option is  not  necessary  unless
        !            51:      the  terminal type does not match the entry in the /etc/htmp
        !            52:      data base.)
        !            53: 
        !            54: QUICK REFERENCE
        !            55:      When the program prompts by typing only your color,  type  a
        !            56:      space or carriage return to roll, or
