I apologize for cross posting and for the extended Cc list but I wish to correct an error I made in a previous comment in this thread.

In an email off-list referring to my suspicion stated in the above sentence, Tim Daly told me that: "This statement is clearly false." and asked that I stop posting statements that imply that he is somehow at fault without checking the facts with him first. I think that is a reasonable request and I regret that I made such a rash comment without thinking about it first. After reviewing all of the comments I could find in the axiom-devel email list archives, I could not find any evidence to support my suspicion. > Tim has said publicly that he was > fundamentally against the decision to implement Aldor that way it was > implemented at IBM.

This statement, while presumably correct (but again I admit that I did not actually check with Tim that this accurately reflects his current view), is not proper grounds for my previously stated suspicion. So the reasons why Aldor was not included in the open source release of Axiom must be of a different nature. ----- One factor may have just been a matter of timing. The Aldor component of the commercial version of Axiom was actually publicly released *before* the rest of Axiom and under a different (not open source) license when aldor.org was created. It is only now that aldor.org and NAG have agreed on a more open license (APL2). However because of the non-commerical use clause the new license is still not completely compatible with Axiom's license so it is currently not possible to combine them both into a single GPL compatible release. But as I understand it (which might be incorrect), it would be possible to release the Axiom+Aldor combination under APL2 since Axiom's modified BSD license is technically compatible with both GPL and APL2. However I am not sure whether there is anyone currently interested and willing to do this. > ...
