  <blockquote>
    <p>The --deployment flags adds the following defaults:</p>
    
    <p>...</p>
    
    <p>If you have run <code>bundle pack</code>, checked in the <code>vendor/cache</code> directory,
    and do not have any git gems, Bundler will not contact the internet
    while installing your bundle.</p>
  </blockquote>
  
  <p>Questions:</p>
  
  <ol>
  <li><p>is <code>bundle pack</code> the same as <code>bundle package</code>? If not then, as <code>bundle -h</code> doesn't show any details about <code>bundle pack</code>, how do you find out more about <code>bundle pack</code> (other than trawling through Google results!)</p></li>
  <li><p>does "checked in the <code>vendor/cache</code>" mean checked into git? And, if so, how does <code>bundler</code> know you've checked it in?</p></li>
  </ol>
