Brain and Wolfgang,
This sort of clarification is exactly what we needed to hear. It sounds
like we can begin working portions of Colt now.
My question to Wolfgang is, to avoid fracturing Colt into multiple
implementations, we could decided between two possible approaches.

Mark,
I am not worried about fracturing. My understanding is that you
wouldn't start doing colt releases build by apache, right? You'd rather
take some parts or derivatives of the code and add them to commons-math
CVS as you see fit (probably in a significantly refactored/modified
form). I

I am posting this to the Licensing list as well because it is very
unclear how to proceed and we dearly need their advice on this subject.
Licensing, the issue has to do with policy for adding code from a
external project, which the author has approved our usage of via email.
Hi, let me briefly introduce myself. I'm the author of Colt which has
the BSD-style license you referred to below.
I encourage you to take code or ideas from Colt, as you see fit, and as
you see compatible with Apache licensing policy.
I wrote this code some six years ago while working at
Hello Wolfgang,
You jogged my memory concerning our discussion on this subject some time
ago. You had given me a contact (James Casey) at CERN to discuss this
subject further and I think the subject slipped off the radar at that
point. Here was that old thread. I've cc'd him on this message to
