dab -- Dots and Boxes game
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. Supported 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 com- puter. The first argument 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. If the dimensions specified are 0 then the maximum dimensions for the size of the screen are used.
