No. But I don't think it matters because these are fonts that will not be "binary linked" with Sage at runtime, so it isn't necessary that their copyright be compatible with the GPL. That said, we need clarification regarding the statement "This fonts cannot be sold or distributed with any commercial product or used in any commercial organization without additional agreement with author. If you want to charge a small fee via distribution these fonts or any derivations from this fonts, you should contact the author." We need clarification, since we fully *do* intend to sell Sage. E.g., I sold a copy the other day in my office to a retired Boeing engineer for $20 (he wouldn't take no for an answer). And we'll likely also sell Sage online via lulo (as Robert Bradshaw mentioned). However, Sage is not-for-profit, so it's unclear whether it counts as "any commercial product". Anyway, I would be most comfortable if we found out from the jsmath author (Davide Cervone, who I've cc'd and who sometimes reads sage-devel) whether it is ok with him if we distribute the jsmath fons with the sage distribution, even if said distribution could in some cases be sold (to support our project). --William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
