title: $on event callback parameters
body: <p>In my .run function I have something like:</p>
  
  <pre><code>$rootScope.$on("$routeChangeSuccess", function(event, args){...})
  </code></pre>
  
  <p>(Angular ver 1.2.10)</p>
  
  <p>[edit]
  Where in the documentation can I find out what is passed for args for the event $routeChangeSuccess?</p>
