[Mesa-users] ./re functionality for cluster

[amber lauer]

I think this is what I will actually have to do, either that or use Rob
Farmer's method. Right now I have it set up to check for files inside
./photos, but I don't think I can check for a file inside a folder if it
doesn't exist, at least I don't think the script will run correctly.
