[Boost-build] [Build] problem including jamfiles

Given a project tree like this:

    top/
        jamfile.jam        # contains "include top.jam ;"
        top.jam
        sub/
            jamfile.jam    # contains "include sub,jam ;"
            sub,jam

then in top/sub bjam complains there is no such file as top.jam.

Clearly the ancestral jamfiles are being processed in the directory in
which bjam is launched rather than in their respective directories.

1.  Is this intentional?  If so, what is the rationale?

2.  Is there a work-around such that the parental jamfile can include
another file from its location?

Thanks for any clarification.
