This is what I was looking for.

Unfortunately, it seems it's only usable to divide tests, examples and 
documentation, and not headers, sources or usage requirements.

This is not what I'm seeing. Shouldn't it be that instead?

BOOST_ROOT/libs
+-library_name
    +-include
    | +-boost
    | +-library_name
    |     +-...
    +-sublib_name1
    | +-test
    | | +-Jamfile.v2
    | +-example
    +-sublib_name2
    | +-test
    | | +-Jamfile.v2
    | +-example
    +-(file)sublibs

What I would want, however, is

BOOST_ROOT/libs
+-library_name
    +-sublib_name1
    | +-include
    | | +-boost
    | | | +-sublib_name1
    | | | | +-...
    | +-test
    | | +-Jamfile.v2
    | +-example
    | +-build
    | | +-Jamfile.v2
    | +-src
    +-sublib_name2
    | +-include
    | | +-boost
    | | | +-sublib_name2
    | | | | +-...
    | +-test
    | | +-Jamfile.v2
    | +-example
    | +-build
    | | +-Jamfile.v2
    | +-src
    +-(file)sublibs

That's a bit tedious.
Shouldn't this be automatically computed?
