I think that this would require that each library specify
a) which headers belong to it.
b) what other libraries it depends on.

Alternately...

A library can specify its headers and the dependencies can be
found automatically.

The former is probably safer, since header scanning is imperfect.

Before I work on this, I'd like to be clear on exactly what the behavior
ought to be.  The current behavior is that the default build
will be set according to --build-type=... with the default being
--build-type=minimal only if the current working directory is
BOOST_ROOT.  This is set in Jamroot's project default-build.

I think that the correct behavior is to apply the default build only to

/boost//install
/boost//stage
/boost//build_all
and the targets created by boost_install.

In Christ,
