This is not a new library, but I should add something to the release
notes; I will do that today. How do I change that page?

This code could not be directly within libs/graph/ because there would be
a circular dependency: graph_parallel depends on mpi, which depends on
graph. I had planned to put the parallel graph code into
libs/graph/parallel/ (like the headers are within boost/), but the CMake
build system for Boost is unable to handle a library that is not at the
top level of libs/ as far as I know. I do not believe moving the code to
libs/graph/parallel would be a problem for Boost.Build. I am still open
to that move (I would actually prefer graph/parallel/) if CMake is not
considered to be a problem.
