TL;DR: You injected way more meaning into what I said. To the point of
mischaracterizing my intentions of simple declarative information.

Yes, I gave technical declarative information. I don't understand how you
ascertained anything past my technical statement.

I fixed the spelling mistake in that for you ;-)

Yes, what I chose to create was "Boost Build" and "Boost Predef".

Correct, I'm not done.

Yep, I continually work on documentation improvements. For example spending
a year converting Boost Build documentation to a format that was a
magnitude easier for myself and others to contribute to. Which has worked
splendidly as we've gotten a handful of outside contributions in both
general improvement and new features with accompanying documentation.

Right. Which is why Boost Build and Boost Predef Documentation is partially
embedded in the source code and is in a simple text format. As it makes
it's more likely to get updated and be accurate. And that has been proven
to work rather well as experience with it has shown.

I'm not tired of that. But let me clarify my original statement.. The
installation and buildid features of "Boost C++ Libraries" are not part of
"Boost Build" (B2). B2 implements a build system that provides supporting
mechanisms to those features but does not contain them itself. They are
properly features of "Boost C++ Libraries" only. As a concrete delineation
of that consider this github search <
https://github.com/search?q=org%3Aboostorg+buildid&type=Code> for "buildid"
in the entirety of all the Boost libraries. You can observe that the places
where that is present are in the super-project and in Boost.Config. Hence
_not_ in Boost Build. As such, my original key point, that such
documentation belongs where it currently is. And perhaps, and almost
certainly, as additions to the "Getting Started" documentation. But also
that it could be added in the wiki where it is more amenable public
contribution. I did not at any time say that such documentation should not
be written.
