You are always going to be welcome. I always feel like a Johnny come
lately with regard to Sage, even though I started contributing to Sage
with my qsieve about 2.5 years ago. In contrast, you were there, right
in the guts of the thing, right from the start! Your contribution has
always been, and I am certain always will be viewed as vital.

I'm sorry for making you feel depressed.

I applaud your efforts, which have been going on for some time now, to
engage in shuttle diplomacy. But even if there weren't personality
issues involved, there is no clear path towards reconciling the two
projects. It's not even clear what we *could* do, even if we were
willing to. The philosophies behind the two projects are just too
different. For now, as far as I can tell, things just have to be this
way. At the worst, there will be some duplicated effort, and both
projects will be pushed to produce better, faster, more impressive
code than they otherwise would have. That will benefit everyone.

My original intention when I realised that TG wasn't going to
entertain changing the license is that Torbjorn and I could reach some
kind of code sharing agreement. But that is tantamount to asking him
to relicense everything LGPL v2+ and for us to assign our copyright to
FSF. As noble as the intention may be, there simply isn't any way
around that. So, whilst I do applaud and thank you for your efforts in
the diplomacy, I think it can't lead anywhere productive for now.
Perhaps one day FSF will totally deprecate LGPL and introduce a GPL
v4. Perhaps this will please everyone, both projects will switch (that
would be an option right, as we both use + in our licenses) and
everything will be rosy again. Who knows, perhaps in our old age, I'll
invite TG to my place for a beer and we'll laugh about the current
misunderstandings.

In the mean time, I do think you have a mandate to give Sage users an
option to use GMP, and people seem to want that. You and TG should
both be pleased with that vote of confidence. But in terms of
strategic directions for Sage, MPIR fits into that much better than
GMP does at present, IMO. I am sure if MPIR doesn't deliver for
people, then that will be reappraised.

Bill.
