Number Fill-Ins Puzzle Generator

This console Perl application generates number fill-ins puzzles. These puzzles are like crosswords, but easier. You're given a puzzle with one number filled in, and you must fill in the remainder of the puzzle with the numbers provided. This application is intended to serve as a backend to other applications which read the generated puzzles files and present them in human-readable format. Designed to run on any modern UNIX-compatible operating system (Linux, BSD, MacOSX, etc).
