So I have the basic hello world code running from the first example on the Documentation page.
I wanted to add the ability to serve static files, so I added a line that I thought would do what I wanted. 

auto router = new URLRouter;
router.get("/index.html", &index);
router.get("/static/*", serveStaticFiles("public/"));

However... 

$ file public/other.html
  public/other.html: HTML document, ASCII text
$ curl localhost:8729/static/other.html       
  404 - Not Found

What am I missing?
