I am under the impression that he started coding before Aldor become "semi-free" - see below, but I guess he needs to tell his side of the story. > Is there a problem with the license of the aldor compiler > (aldor-combinat itself is GPL2). Yep, I believe so. From the website; Version 1.1 of Aldor has been released in source form under the Aldor Public License 2.0. This allows free non-commercial use, modification and re-distribution of Aldor software This is only my personal opinion: "This allows free non-commercial use" seems unacceptable to the principles of Sage. Am I mistaken or does this not apply to the aldor compiler itself? > (Sorry that I haven't been reading much on the Sage-devel list.) > ;) > Ralf Hemmecke > > > > > --~--~---------~--~----~------------~-------~--~----~ 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://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
