> 1) Make these toys in lisp/play optionally available from
> elpa.gnu.org/packages, but do not ship them by default within
> Emacs.
> 
> Advantage of solution:
> 1) All problems go away
> 2) Simple lisp game sources now easily accessible right from common browser
> for fun & inspiration without having to download 56M tar.gz editor with them.
> 3) Fair towards other toys, considering sokoban and wpuzzle are there but 
> don't
> ship by default.
