1. To use the sudoku solver, just unpack the package to a directory of your choice.
2. Place the examples in a local directory on your client.
3. !!! Create a subdirectory of the directory where you put the Sudoku Solver classes,
call it temp, and make sure you can move uploaded files (the Sudoku examples) 
to this directory, by making it writable. 
4. Start the solver by executing the sudoku.php script.

A PHP4 version can be found in the sudoku4 subdirectory (note point 3 also)
