title: How are AngularJS and AngularUI related to each other?
body: <p>I wonder what the relationship between <a href="http://angularjs.org/">AngularJS</a> and <a href="http://angular-ui.github.com/">AngularUI</a> is?</p>
  
  <p>A quick look at the contributors' list seems to say that both projects are developed by independent teams.</p>
  
  <p>Does anyone know more about the relationship between these two projects?</p>
  
  <p>What's especially interesting is the question whether things provided by AngularUI will (one day) become merged into AngularJS. This would be extremly useful for things such as <a href="https://github.com/angular-ui/ui-router">ui-router</a>.</p>
  
  <p>Anyone know more than me ;-)?</p>
