Hey Rob, looking at your work on structuring many jobs
<http://cococubed.asu.edu/mesa_market/many_jobs.html> it looks like this is
what you do, via


But there's not really a discussion in the guide of restart_photo. So can I
assume in that script that the effect will be to run MESA with whatever
photo is currently the restart_photo, or from the start if none exists yet?
Again thanks for that guide. It was a lifesaver.
