Back when we started writing the Message Passing library, we decided
to put it into the "parallel" subdirectory (then the "mpi" sub-sub-
directory), because we were hoping that "parallel" could become a top-
level categorization for various parallel-programming libraries...
threads, mpi, shared memory, etc. That may happen some day (when we
manage to break Boost into pieces), but for now it's just a pain.
Users need to using the longish namespace "boost::parallel::mpi",
file names "boost/parallel/mpi", and run bjam with "bjam --with-
parallel" (rather than "--with-mpi").
So, unless I hear screams, I'm going to move libs/parallel into libs/
mpi, boost/parallel into boost/mpi, and simplify its underlying
directory structure a bit. When the time comes to split up Boost, and
if it involves deeper namespaces, we'll make the change again then.
For now, simpler is better.
Cheers,
Doug
