the web, which I hope will also end up being extended to generate both Windows and X icons for each individual puzzle. The mechanism is: for each puzzle there's a save file in the `icons' subdirectory showing a game state which I think is a decent illustration of the puzzle, and then there's a nasty set of scripts which runs each puzzle binary, loads that save file, grabs a screenshot using xwd, and munges it into shape. In order to support this I've added two new options (--redo and --windowid) to all the GTK puzzles, which I don't expect ever to be used outside the icons makefile. I've also added two more options (--load and --id) which force a GTK puzzle to treat its command-line option as a save file or as a game ID respectively (the previous behaviour was always to guess, and sometimes it guessed wrong).
