8: .sh NAME
9: backgammon - the game of backgammon
10: .sh SYNOPSIS
11: .bd backgammon
12: [ - ] [ n r w b pr pw pb t\c

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