                if [ "$yesno" = "y" ]; then
                    $BUILD set_fastest;
            
            if [ -s "${CB_OPTIONS}" ]; then
                DL=`grep ^downloadserver= ${CB_OPTIONS} | cut -d= -f2`
                if [ "${DL}" != "" ]; then
                    SERVER=http://${DL}/services
                    FTP_HOST=${DL}
