Hi Daniela,
> against ganga
I was thinking about that. We'll start without any high-level submission
tool, i.e. basic commands. I'll review what you and David say about
ganga. The DIRAC API looks interesting, and I did not know of its
existence. I'll assume it's a "simple" pythonic API that we can use
instead of basic dirac_ui commands. If so, I'll be having a good look at
that.

It turns out that our site admin, John, already provides dirac_ui on our
systems, so we'll be taking advantage of that.
So, thanks for all this information... it will all go back into the user
guide in due course...
