In this case, we can add attributes without making any changes to the format. But in general, I would be strongly against any "magic comment"-style format changes. These would be hard to parse, cause fatal syntax errors on similar-looking comments, and make the file format even cruftier than it already is. The major file format change will be a change toward an extensible file format in which data and file structure are independent, so we will no longer break things by adding features. -- Andrew Poelstra Email: asp11 at sfu.ca OR apoelstra at wpsoftware.net Web: http://www.wpsoftware.net/andrew/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
