I think it would be more useful to have a single file (e.g. JSON) with options and their default values, and generate all other lists from it. > > —Tim > , > > _______________________________________________ > webkit-dev mailing list > [email protected] > https://lists.webkit.org/mailman/listinfo/webkit-dev -- Regards, Konstantin _______________________________________________ webkit-dev mailing list [email protected] https://lists.webkit.org/mailman/listinfo/webkit-dev
