I think this would be useful.

Roland and I have been talking about this for a while -- we really do need
something a little more exhaustive to run every week or so. I assume
redmine would be a good place to put a plan together? Any thoughts on this,
Swedish people who have most of the infrastructure?

I doubt g_energy is the biggest problem timewise, but if it is, then I'd be
happy to work with getting a .edr reading in. Only one routine would need
to be rewritten. I assume someone someone somewhere has a python reader for
gromacs .edr files?

This is something that would be good to start synthesizing. Perhaps when
4.6 is out the first thing all the developers could do is articulate what
they want to see for 5.0 so we can synthesize all these ideas? Would
Redmine be the best place for this discussion?
