title: DiscoverMeteor: what is the purpose of bundling?
body: <p>In Chapter 2.5 of Discover Meteor by Tom Coleman, the instructions for deploying to EC2 require me to first bundle the app, move the tarball one directory up, then unzip that tarball again, before running node on the app.</p>
  
  <p>This seems rather a tedious procedure as I'll have to bundle and unzip after every commit to test the app. Also, isn't this just the same thing as moving the entire app one directory up, or does bundling then unzipping do some magic that makes it run right?</p>
