You can set up a repo to build outside of the boost tree, I've done it
for quickbook in the past. The problem is that when you're building
documentation, boost.build expects the tools to be at the relevant
location. Some of the tests run inspect in a similar manner.
This is also an issue for using the tools outside of boost, since
everything is in the tree, no one installs anything. The python script
for rebuilding the website was meant to be really simple to use, but
isn't because there's no standard way to find quickbook.

Is that the case for any of our existing tools?

Ideally the tools shouldn't need to be updated and rebuilt too often.
Some of them are now packaged on Debian, and perhaps elsewhere, so I'd
like to use that. I'd prefer to use a stable binary, even if it's a
bit out of date. Boost.Build is a bit annoying in this regard because
you can install a standalone version including the various jamfiles it
come with, but when building anything from boost it uses the scripts
from boost rather than the installation, which might not match.
