dab [-aw] [-n ngames] [-p ⟨c|h⟩⟨c|h⟩] [xdim [ydim]]
dab is a game where each player tries to complete the most boxes. A turn consists of
putting one border of a box; the player setting the fourth and final border of a box gets
the point for the box and has another turn.
The keys used are the vi keys: k for up, j for down, h for left, and l for right. To switch
between even and odd rows, use one of the following keys: u (diagonal right up), y (diagonal
left up), b (diagonal left down), n (diagonal right down); ⟨space⟩ sets a new border, CTRL-L
and CTRL-R redraw the screen, and q quits the game.
Support options are:
-a Don't use the alternate character set.
-n ngames ngames games will be played. (Especially useful in -p cc mode.)
-p ⟨c|h⟩⟨c|h⟩ Select which of the two players is a human or a computer. The first argu‐
ment is the first player; c stands for computer and h for human.
-w Wait for a character press between games.
xdim and ydim define the size of the board in the x and y dimensions.
