RE: the big news

Well, I think adoption might be premature, in that the plan is not to orphan
ATLAS in the first place. As I said before, I plan to still support, but
just not at the same levels.
The first place I'd hope to get help is in the user question area, as I
mentioned in the first mail. The second is in getting stable releases out.
The way this used to work, is that Antoine and I would decide on a code
freeze, and then test on as many platforms as possible, over the course of
a month or two, until we had a stable release. This is what will no longer
So, what seems viable to me is have developer releases, and keep track of where
they have been installed. At some point we stop accepting new code,
applying only bug fixes. After a given point, the last bug-fixed developer
release rolls into a new stable. There's a lot of stuff glossed over that
will have to be nailed down, but that certainly seems to be a viable idea
to me . . .
We can use CVS branch to allow a frozen developer branch (heading towards
stable), that wouldn't effect continued developer work as well.
In the coming time, I will be posting other stuff to the developer website
that will facilitate this kind of deal. For instance, Antoine developed
a test suite that we run to verify ATLAS, and I'll be posting it . . .
Anyway, I hope not to orphan the package, but rather feel that since it
is out of it's adolescence, perhaps it can safely have a greater amount
of independence :)
However, if R developers (I don't know much about the R project, except that
R can utilize ATLAS) would help with the testing and so on, that would
certainly be great. It makes some sense that packages that use ATLAS
could help out in that regard if they have the time, often perhaps as part
of their own internal testing . . .
