Vladimir -

What would be the proper way to make this compile from the top directory?  I
believe I can add bhome as a default include path to all subprojects, but I
don't know the syntax.

I'm still confused as to why I can't build from the top dir, when bhome is
properly included in the sub-project's Jamfile?

Thanks,
