I believe the settings in the first Jamroot above the Jamfile will
propagate downward. That seems to be our experience, though I can't say
we did more than a cursory check. We do have similar requirements in
our Jamroot and they seem to propagate downwards to all our executables.
  Perhaps they can be overridden though.

It's a little confusing because a project can contain projects. But I
think I got it.
