This is a comprehensive "word game" word list for UNIX/Linux. It is a superset of the author's ENABLE list, the "OSW", and various lists researched by the author's colleague, Alan Beale. At 264,093 words, it is the largest list of its kind, suitable for use in all manners of crossword-type board games and word construction games, as well as for a spell checker dictionary. The YAWL package now includes two anagramming utilities (supplied as source code, handled by the included Makefile). There is also a shell script that extends the UNIX "strings" system command. This is the word list package recommended for the author's Quackey word game.
