    group.  This option requires the game to have the \"setgid\" bit set on its
    permissions, and thus this option requires root when installing.

--with-private-dirs
    This configures the game to store savefiles and scorefiles for each user
    in that user's home directory.  The game requires no special privileges if
    you do this, and should be used for most installations of the game. This
    is the default, if you specify none of these three options.
