    dvd+rw-tools doesn't support -RAM as well as other formats, in part because the
    {+,-}R(W) formats are much more common, in part because there are some pretty
    serious quirks in the older drives, but improvements would be welcome.

    I'd be happy to review or test them first if you'd like, but any changes of
    this sort really ought to go upstream to Andy Polyakov <appro@fy.chalmers.se>
    or to the cdwrite mailing list at <cdwrite@other.debian.org>.
