title: can grunt automatically include all my js in index.html?
body: <p>I'm new to grunt.  I'm coming from rails and getting into angular.  From what I can see grunt usemin can replace <code>&lt;script src=...&gt;</code> between build directives and replace that with a single minified js during grunt build.  That's great for deployment.  </p>
  
  <p>However whenever I add new angular controllers during development, I also have to remember to add them to my index.html.  That's a hassle, and the same goes for if I move my feature folders around, I have to change all my src paths in index.html.  </p>
  
  <p>It would be nice if in development, grunt would watch all my <code>src/**/*.js</code> and automatically add them all to index.html for me... similar to rails asset pipeline and asset manifest that just does require_tree when you're developing.  You can put files anywhere and it's automatically available.  </p>
  
  <p>Is there such an existing solution or example for a grunt watcher?  Thanks  </p>
