   3   To start retrieving location information, you need to create a location watch
   4   by calling $(ref:location.watchLocation), passing in
   5   the location watch details via the <code>requestInfo</code> parameter:
   6 </p>
   7
   8 <pre>chrome.location.watchLocation(name, requestInfo);</pre>
   9 <p>
  10   You also need to add a listener
  11   for the $(ref:location.onLocationUpdate) event.
  12   Chrome will fire this event after you create your location watch, and
  13   it will keep firing the event every time the geographic
  14   location of the host machine changes, until you call $(ref:location.clearWatch).
  15 </p>

  17   Here's sample code
  18   to listen for location updates:
  19 </p>
  20 <pre>
  21   chrome.location.onLocationUpdate.addListener(function(position) {
  22     console.log(JSON.stringify(position));
  23   });
  24 </pre>
