Sudoku Solver

Description

A simple command line solver for Sudoku puzzles. It can report the steps leading to a solution (how field by field is filled in), together with a justification for the digit set in each field.

If the solution needs backtracking, this solver finds a way to solve the puzzle that needs the least backtracking depth. If there are multiple solutions, it can be requested to list them all.

Call the program with no arguments to see a list of options.
