title: What does `g8` do when installing Typesafe Stack 2.0
body: <p>So I just installed the Typesafe Stack via the universal install (download a .zip and un-zipping it into my <code>/usr/local</code> directory. I looked at the website and it mentioned <code>sbt</code> and <code>g8</code>, so I first typed <code>sbt</code> to see what would happen and it just gave me a little error about how there was no project in the current directoy. Then I typed <code>g8</code> and it started downloading a bunch of stuff... though I'm not sure what. Can anyone tell me? Picture attached.</p>
  
  <p>Additionally, does the Typesafe stack come with Scala and Akka? The website seems to say it does, but if I remove my original Scala 2.9 path from <code>.bash_profile</code> and then restart Terminal, it complains that it doesn't exist.</p>
