I know that, I was just trying to spin it.

Please forgive me for saying this is a bit far-fetched. If I propose a
library for inclusion and it gets rejected, fine, I still have a
library. If I propose a build system (arguably more work than a typical
library) and it gets rejected, I've got nothing. A new library doesn't
typically require everybody to change the way they do business
throughout the entire release cycle, from development to testing, and
therefore doesn't encounter the inertia of the community. For that
matter, I'm having trouble imagining how one would merge a build system
from trunk to release. This is the same problem that provoked this

Well we thought we would get some users, and we got lots of them on the
end-users' side, but it didn't catch on with boost developers as I'd
hoped. C'est la vie.

I think the better way is:

* A few notes in Getting Started with pointers to the cmake stuff
* One root CMakeLists.txt that just prints a message on where to get
* A link to some boost-cmake tarball area alongside the standard boost

That's the new proposal.

I doubt that it is necessary to agree at this point. That stuff either
comes out of release or goes out broken.

I don't see it that way. We have 115 people on the boost-cmake list,
and a bunch of them were really helpful (thanks guys) in tuning up the
build for 1.40.0, and we'll do it again in a few weeks for 1.41.0.
Participation has been signficantly wider than when it was just Doug and
I. There are docs, happy users, all that stuff.

They've got that. It's done.
