The tool itself is in tools/boostdep, but I haven't written any
documentation yet.

The range -> algorithm dependency has been removed by a recent pull request
from Stephen Kelly, so this cycle has at least been taken care of.

Just headers.

Not necessarily to build, as it only tracks headers. If you include a header
of level N, compilation should succeed if you have everything <= N
installed, assuming prebuilt or header-only libraries. In the absence of
cycles, it would be < N.

<boost/spirit/home/support/detail/lexer/serialise.hpp> includes

There is a newer report at by the way.
