Josh and I have just brought over the changes from a branch where we
were working to make orterun's --host option work properly. --host now
has clearly defined semantics and we think it follows the Law of Least
Astonishment -- see the FAQ for details on exactly how to use it:

        http://www.open-mpi.org/faq/?category=running#mpirun-host

We tested it in several environments (no scheduler, PBS, SLURM, BProc,
hostfile), and we think we caught all the corner cases, but would
appreciate if others could give it a whirl.

There's still some more cleanup with RDS/RAS/RMAPS to do after 1.0, but
I think we now have a working --host and that's the most important
thing.
