Sudokut 0.2

Sudokut is a command line sudoku solver.
Sudokut is written in Tcl, a platform-independent scripting language, so it should work on any platform (Unix, Mac OS X, Windows) provided a Tcl interpeter is installed (which isnormally the case by default on Unix and Mac OS X).
It is quite fast (less than one second for medium force sudokus, approx 4 seconds for the most difficult ones).
The command has several options. The package comes with a detailed help file.
sudokut is an Open Source Project. Its source code is freely available and can be freely distributed and modified provided you respect the licensing terms.

- new -s option to obtain suggestions about the next step
- new -p option to probe the sudoku using a particular technique
- new -o option to obtain only the first solution in the case of a multiple solutions puzzle
- new -n option to disable backtracking
- more solving techniques are supported: block to row/col reduction, block to block reduction, naked pairs reduction, x-wing reduction.
