title: How is recwatch supposed to work?
body: <p>I'm trying to get <a href="https://godoc.org/github.com/xyproto/recwatch#pkg-index" rel="nofollow">recwatch</a> to work. I'm confused by its interface, though. Yes, I can make a watcher and add folders to it, but there does not seem to be a way to start an event loop that will allow me to receive notifications.</p>
  
  <p>In the <a href="https://github.com/nathany/looper/blob/bc28a212ab3643c208f17fc7bfb628671cb018c3/watch.go#L48" rel="nofollow">original code</a>, there was a <code>Run</code> receiver for just this purpose.</p>
  
  <p>Am I missing something?</p>
