Yes. You can specify various switches on the mtt command line (see "mtt
--help"). More below.

You can do something like:
mtt --mpi-get --mpi-install --test-get --test-build --file
...whatever... --scratch ...whatever...
This will download the MPI, install the MPI, get any test sources, and build
them all against all the MPI's. Alternatively, you can do:
mtt --no-test-run --file ... --scratch ...
Because really you want to do everything *except* run the tests (right?).
The only problem with this is that MTT does not yet support chaining well;
so there's no real notification that the builds have all finished other than
the mtt client finishes.

Right now, MTT will do everything in the INI file -- you can't say "only do
MPI installs A, B, and C" (and assumedly skip some other sections, such as
D, E, and F). So it would probably be a PITA, but you could have different
INI files with different configurations if you need finer-grained control.

Yes. The only bummer is that we currently provide no assistance on the
"wait for it to complete" step. :-\
