Jamroot combines the top Jamfile and project-root.jam; you can just
dump everything in there. But it's not crucial.

Technically, it probably doesn't matter :) but in this case you're
right it should clearly go on the unit-test.

Oh, well, that's dumb. We should fix that.

I think the information you want is at

in that case.
