The object of
boggle is to find as many words as possible on the Boggle board within the three minute time limit. A Boggle board is a four by four arrangement of Boggle cubes, each side of each cube displaying a letter of the alphabet or `qu'. Words are formed by finding a sequence of cubes (letters) that are in the game's dictionary. The (N+1)th cube in the word must be horizontally, vertically, or diagonally adjacent to the Nth cube. Cubes cannot be reused. Words consist solely of lower case letters and must be at least 3 letters long.
Command line flags can be given to change the rules of the game.
-b

-d
Enable debugging output.
-s seed
Specify a seed seed other than the time of day.
-t time
Set the time limit for each game from the default 3 minutes to time seconds.
-w length
Change the minimum word length from 3 letters to length.
