Dear Stephen, dear Mike

as you might know, I have built some scripts in FriCAS (a fork of Axiom) ( in order to build from scratch. Unfortunately, I can neither distribute nor some necessary .as files under the same license as FriCAS (mBSD), since this code is only available under the Aldor Public License 2.0.

I hereby kindly ask you to release the following files under a BSD license (same as for the Axiom code).

Furthermore, in order to distribute a precompiled together with FriCAS, it would be helpful to also release


under a BSD license. For '', also releasing the sources under a BSD license would be good, but I explicitly ask for the release of the .ao format.

Please help the FriCAS project and don't let Aldor die.

Has meanwhile anything been done to release all of the Aldor compiler+library sources under a GPL-compatible license?

Thank you for your time.

Yours sincerely

Mike, Stephen,

I have recently decided after two years that Aldor was
never going to become free enough to be integrated back
into Axiom. The FriCAS project has been trying to keep
the connection alive.

It would seem that changing the license on the FriCAS
related files would at least help them in their efforts
to keep the connection alive. Thus, I'm adding my voice
to the request to make this change.

I realize that such changes involve your legal department
and come at a non-trivial cost. I also realize that you
may have prior agreements that prevent it. In any case,
I think that the sense of frustration in FriCAS appears
to be reaching a critical tipping point and this is likely
to end with Aldor being deleted.
