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

-p <c|h><c|h>
