The other day I found it useful for a (silly) special purpose to

generate a thousand saved-game files of randomly generated puzzles.
On the general principle that if I find it useful someone else
conceivably might too, add a --save option to the Unix puzzle
binaries, for use with --generate in much the same way as --print.
