The CGI crossword puzzle building system consists of two programs, buildcwd.cgi and playcwd.cgi for building new crossword puzzles and playing crossword puzzles respectively. Players may play the puzzle, see the solution if they have the solution password, and may be able to see an intermediate score if the puzzle was configured for that feature. Comes with a readme file for detail info on script installation. Unicode multi-lingual extension includes modules for creating/playing puzzles in French, Spanish, and Hebrew.
