title: Can I download all of rubygems.org?
body: <p>I have an air gapped network that I use for development. Is there any way that I can easily download a snapshot of rubygems.org to import to the gem server running on said network?</p>
  
  <p>I saw the help article on the rubygems site about how to get specific gems with no network:</p>
  
  <pre><code>$ gem install rails -i repo --no-rdoc --no-ri
  </code></pre>
  
  <p>I want to try to get everything at once. Any idea how big this would be even without the rdoc and ri?</p>
