ACKNOWLEDGEMENTS

Thanks to:

Brian Helterline for help in solving 6x6 puzzles and making this more configurable.

Jean-Pierre Vidal for providing puzzles that the previous version could not solve.

Eugene Kulesha (http://search.cpan.org/~jset/) for providing a test that I could not initially pass and for the idea of keeping test data in data files rather than in the tests themselves.

Tom Wyant (http://search.cpan.org/~wyant/)) for the idea of using dots rather than spaces to represent unknowns in the text representation of the board.
