The bundle provides three packages: printsudoku, which provides
a command \sudoku whose argument is the name of a file
containing a puzzle specification; solvesudoku, which attempts
to find a solution to the puzzle in the file named in the
argument; and createsudoku, which uses the random package to
generate a puzzle according to a bunch of parameters that the
user sets via macros. The bundle comes with a set of ready-
prepared puzzle files.
