title: Akka remote configuration issue
body: <p>There's something I don't understand about <code>akka.conf</code> configuration file when working with Akka actor model (for Java but must be the same for Scala).</p>
  <p>For example when using remote module :</p>
  <p>I sometimes see something like this :</p>
  <pre><code>akka {
    actor {
      provider = &quot;akka.remote.RemoteActorRefProvider&quot;
    }
    
    remote {
  </code></pre>
  <p>And sometimes :</p>
  <pre><code>akka {
    actor {
      provider = remote
    }
    
    remote {
  </code></pre>
  <p>First whatis the expected value for key <code>provider</code> ? Sometimes it is a classname, sometimes it is juste <code>remote</code>
  By the way, why it is <code>remote</code> and not <code>akka.remote</code> considering remote is under <code>akka</code> namespace ?</p>
