That's a very good point/question. It is one thing for us to work on making "calculus not use Maxima much", and quite another to have "remove maxima from standard sage" as a goal. I'm asking about viability of the latter rather than the former. I noticed Burcin said the following in IRC, which is related to the above distinction: "12:58 < burcin> I thought this was the goal all along, I don't see why we needed a new discussion about this" One reason we need a new discussion is that in August 2008 you and I spent a few weeks creating Pynac and getting it into Sage. I did nothing subsequently on that project (Pynac, etc.) during the last 4 months, and I think this discussion is a good way to also revisit that. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
