Sadly not - moved to higher things some years ago.

I think that the reason is that almost everyone else is using Quickbook to generate the Boostbook, so that it is entirely transparent to them. Snippets of examples and tests are sucked in by lines of Quickbook, but the docs, examples and tests, and the jamfiles to run them otherwise entirely separate.
