Thanks for sending this summary along. It really helps to let us see
what you have in the pipeline. Most of this stuff is _really_
exciting. See my comments inline.

Sounds like a good idea. Personally, I think migrating completely to
autoconf 2.59 would be fine for the 21.5 (22.0) release.

This _sounds_ like a win, but how disruptive would this be?

Personally, I'd rather not slow down startup at all, but I'm open to

As Michael has pointed out, I think we've discussed this one to death,
and I wouldn't want to see a change in this area.

Sounds really good. Potentially disruptive, but the gain is probably
worth the pain. Definitely needs to be finished, though.

So, my bottom line is that much of what you propose is great stuff -
big visionary changes that will help move the code base forward
(consolidating X/GTK, etc), most of the rest of it is conceptually ver
good but potentially very disruptive (perhaps buggy) stuff and the
last bit (init vs. customize) is not OK.
So, I don't think we can accept this whole-hog. If you were willing
to break out the pieces that the review board found unacceptable, I
would be grateful for you to check this in, provided:
1. You finished off the unfinished parts.
2. You posted the code (or checked it in on a branch) for a week or 2
so we could all build and experiment with it. Ideally, you'd give
us a little warning beforehand so we could clear our decks and
spend some time working with the new code. 1 or 2 weeks after you
send out the patch (or check in on a branch), I would be OK with
your checking in to 21.5,
3. This is probably the most important part - you have to promise to
stay around to work through the issues that will inevitably arise
after your checkins. You have made enormous contributions to the
XEmacs project, but when you disappear for long stretches of time,
the rest of us don't know how to proceed with the codebase. It's
as if in the evolution of the XEmacs project, we don't quite reach
the equilibrium part of the punctuated equilibrium, because you
almost deliver us to the next level but then you disappear. To be
fair, this time you have been much easier to work with and I know
that you have worked hard to get here. Also, there's no way to
tell if your RSI might act up, so you can't make promises on that
score, but I'm asking for a good faith promise that you will
attempt to stick with us and work with us as we use your code as
the basis for a revitalized XEmacs 22.0.
What do you think?
