A note -- if you're linking to arXiv, it's better to link to the abstract (http://arxiv.org/abs/1406.1886) rather than directly to the PDF. From the abstract, one can easily click through to the PDF; not so the reverse. And the abstract allows one to do things like see different versions of the paper, search for other things by the same authors, etc. Thank you!
Ok, url changed from http://arxiv.org/pdf/1406.1886.pdf. We should probably write code to do that conversion automatically, since this has come up from time to time.
