I agree. There are quite a few idiosyncrasies that have crept into b2 to
support Boost-specific policies that I think a general-purpose build
tool shouldn't have (or that should be captured in a higher layer to
adapt the tool to a specific work-flow), but there is a substantial set
of generic features that each and every build system needs. Agreeing on
that core set of features and putting that into a form that's reusable
by others to define their own workflows would be very valuable.

I have tried to do that in Faber (where bjam survived as the scheduler,
but everything on top of it is rewritten in Python from scratch), and I
would definitely like to compare and share with others.
