[Swift-devel] Re: osg question: how to find sites' health

[Daniel S. Katz]

I think this would be a useful thing for Allan work on under ExTENCI, after this week, and secondary to getting the SCEC code running and tested.

I'm also trying to get more ExTENCI funds, and a general purpose tool might be a good deliverable for that.
