I'd searched high and low for the answer to this, and now that I've found it, I want to post it. I guess the real challenge, however, is getting a search engine to render up the goods: doing a Google search for "./" or "dot slash" didn't return much, and I don't have any bright ideas, other than spelling it out as dot slash.

So, that's the issue though - what does ./ mean in a Linux path?
