  This is our preference. Why? It is jsut as stable as tarballs because you can
clone to any particular revision, BUT its more flexible because you can easily

  The DOE really frowns on this I believe. We discuss a lot of DOE internal stuff
on it. However, it there were an archived list to Cc, we could talk about doing that.

  Well, we get anywhere from 50-200 per day, so I think we can probably handle some more. In
my experience there are a lot up front with a new community,but it rapidly tails off.
