Hi Martin,

do you think this is a reasonable condition for Apple in configure?

         enable browser_launch
         if test -n "$sysroot"; then
             case "$sysroot" in
                 */iPhone*.sdk|\
                 */AppleTV*.sdk|\
                 */WatchOS*.sdk|\
                 */BridgeOS*.sdk)
                     disable browser_launch
                     ;;
             esac
         fi

Can you add an option to avoid launching browser, and just gen html?

Regards,
Gyan
