YAML has facilities for this: both creating user-defined types, and concatenating multiple documents so that we can preface every .pcb file with a global types file. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
