This looks fine. There is one point we may want to clarify/highlight in some
manner. When we reach 1.3.4, the SLURM support changes so things won't work
for LANL's interactive login method (a rather unique one) unless they
upgrade to slurm xxx (forget number - can look it up when I get back).
I'm not sure how to handle that point, though - outside of the tri-labs, who
already know about the restriction, nobody else is likely to notice or care.
So perhaps nothing need be said? I fear the language may get complex, and
wind up confusing people who shouldn't care.
