But to make this clear: Yes, if it's at least a bit possible, I'd like to stay BSD, because clearly the BSD market is good. But if staying BSD means that people will not help with sympy but rather help with a GPLed package, I think that getting the job done (=good symbolics in python) is more important than BSD vs GPL flamewar. We had the discussion BSD/GPL here: http://groups.google.com/group/sympy/browse_thread/thread/e5f77a57874d2135/ a good summary is for example this email: http://groups.google.com/group/sympy/msg/183cad529117b758 Ondrej ------------ But also I think it's good to say my own opinion on this, and that is, that I personally think that given that I am paid from tax payers money (i.e. grants, stipends, etc.), which are individuals or companies (in my case mostly Czech and European and soon hopefully US), I really think it's fair if the companies can use the work that was produced by their money in the way they want. I.e. BSD fits nice, GPL doesn't. LGPL is somewhere shady, but many companies don't like it either. But I understand that those are complicated questions and and one argument for (L)GPL is the fear that someone will take the code and close it, improve it, sell it and make a lot of money with BSD, while with GPL he is forced to open it and that is better over all, because it brings the code back to the project, that otherwise would not be available. I believe though that less restrictions are better in the long term, i.e. if people and companies can do things that they want and use code as they want, it is better for all of us in the end. But I am not fundamental on this, as I said above, getting the job done and getting people to work together is way more important for me. If you have opposite opinion than I do, I'd love if you could oppose, but please no flamewars. --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
