Cool. Thanks for pointing this out! The download location is here: http://www.cs.berkeley.edu/~fateman/mma1.6/ and the license is very liberal. I definitely have nothing against making it easier for people to express certain things in Sage, e.g., building on the lisp that we include, or patterns for expressing things that people are used to. > 2.

We are switching to ECL very soon, which promises to be faster than clisp, especially if other groups (e.g., the fricas folks) start using it and pushing it. -- 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 -~----------~----~----~----~------~----~------~--~---
