The following sage-devel thread is also about using XML-RPC with Sage: http://groups.google.com/group/sage-devel/browse_thread/thread/202f9b2323d2771b/71fd656651eceb89 -- Regards Minh Van Nguyen --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
