3: .sh NAME
4: backgammon - the game of backgammon
5: .sh SYNOPSIS
6: .bd backgammon

12: .sh DESCRIPTION
13: This program lets you play backgammon against the computer
14: or against a "friend".
15: All commands only are one letter,
16: so you don't need to type a carriage return,
17: except at the end of a move.
18: The program is mostly self documenting,
19: so that a question mark (?) will usually get some help.
20: If you answer `y' when the program asks if you want the rules,
21: you will get text explaining the rules of the game,
22: some hints on strategy,
23: instruction on how to use the program,
24: and a tutorial consisting of a practice game against the computer.
25: A description of how to use the program can be
26: obtained by answering `y' when it asks if you want instructions.
27: .s3
28: The possible arguments for backgammon
29: (most are unnecesary but some are very convenient)
30: consist of:
31: .ne 11
32: .s3
33: .na
34: .lp 16 8
35: .bn n
36: don't ask for rules or instructions
37: .lp 16 8
38: .bn r
39: player is red (implies n)
40: .lp 16 8
41: .bn w
42: player is white (implies n)
43: .lp 16 8
44: .bn b
45: two players, red and white (implies n)
46: .lp 16 8
47: .bn pr
48: print the board before red's turn
49: .lp 16 8
50: .bn pw
51: print the board before white's turn
52: .lp 16 8
53: .bn pb
54: print the board before both player's turn
55: .lp 16 8
56: .bn t\fiterm
57: terminal is type
58: .it term,
59: uses /etc/termcap
60: .lp 16 8
61: .bn s\fifile
62: recover previously saved game from
63: .it file.
64: (This can also be done by executing the saved file,
65: i.e., typing its name in as a command)
66: .s3
67: .ad
68: .i0
69: Arguments may be optionally preceded by a `-'.
70: Several arguments may be concatenated together,
71: but not after `s' or `t' arguments,
72: since they can be followed by an arbitrary string.
73: Any unrecognized arguments are ignored.
74: An argument of a lone `-' gets a description of possible arguments.
75: .s3
76: If
77: .it term
78: has capabilities for direct cursor movement (see ttycap(VII)),
79: .it backgammon
80: "fixes" the board after each move,
81: so the board does not need to be reprinted,
82: unless the screen suffers some horrendous malady.
83: Also, any `p' option will be ignored.
84: (The `t' option is not necessary unless the terminal type does not match
85: the entry in the /etc/htmp data base.)
86: .sh QUICK\ REFERENCE

88: type a space or carriage return to roll, or
