title: Is it possible to bundle / install gems from a local cache?
body: <p>I have  bunch of gems on my computer that I want to use in a chef recipe.</p>
  
  <p>I know it is possible to put them in a directory like /tmp/gems and just:</p>
  
  <pre><code>cd /tmp/gems
  gem install *.gem
  </code></pre>
  
  <p>Is it possible to put all gems in one directory where I can install them with bundler without downloading them again?</p>
  
  <pre><code>cd /somedir/my_rails_project
  bundle
  </code></pre>
  
  <p>I want to save bandwidth. </p>
