I'm trying to get the contrib agreement signed, but working something
like that through the university legal system will take some time.

Note that the script depends on having condor_status in your path.

Yes. Try:

./ress-to-site-catalog --vo=OSG

Or,

./ress-to-site-catalog --help

We did a quick try, but ran into some problems. Ben knows more.

In general, I think you will run into problem on some sites using
managed-fork, as they might kill the forwarding process you put on their
submit nodes.

I'm still trying to get a feel for this. I think it is a good idea to
start with pretty conservative per-site settings, and try to use many
sites instead.
