Interpreting a license is always a problem. It's a problem for programmers since they are not lawyers to understand all the legal parts to infinite depths and it's a problem for lawyers because they don't understand every little thecnical part. There are always gray zones depending on common sense and intentions. A good rule of thumb about GPL may be to check what GNU or FSF says, recommends or suggests or even how they interpret their own licenses. For this case, they have a point in thier faq (http://www.gnu.org/licenses/gpl-faq.html#GPLOutput): "Is there some way that I can GPL the output people get from use of my program? For example, if my program is used to develop hardware designs, can I require that these designs must be free? In general this is legally impossible; copyright law does not give you any say in the use of the output people make from their data using your program." This clearly applies to PCB but still it's a question how a schematic symbol is related to the final hardware product. Maybe it is worth to ask FSF (in case the symbol and/or footprint is under the GPL). Igor2 P.S. DJ, I tried to send you a mail in private about the challenge boards but your mail server seems to drop my mail considering it a spam. I use the same email address and host as for this mail. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
