- b2 --help: A quick reference for building Boost. This
must not contain any information that is not also
- boost.org/build: Documentation of Boost.Build itself.
Ideally you shouldn't need this unless you're writing Jamfiles.
- getting started guide: Everything you need to know for
working with a packaged release of Boost.
- github wiki: Documentation specific to working from git.

Historically, we've used the wiki for a lot of
documentation targeted at Boost developers.
This page was originally migrated from trac.
I think this information should be separate
from the getting started guide, although
where it should actually live is open to debate.

If that's all you're doing, then you can skip
b2 headers. b2 test will run (part of) b2 headers
on demand. (To be precise, it will update any
headers that are found by the #include scanner).
