title: How to clone a specific version of a git repository?
body: <p>I'm working with symfony2 and I want to backup my vendors in case github is not reachable.</p>
  
  <p>How do I clone a specific Version of a repository?</p>
  
  <p>I want to backup the repositories with help of the vendors-file.</p>
  
  <p>the syntax is something like this:</p>
  
  <pre><code>[symfony]
      git=http://github.com/symfony/symfony.git
      version=v2.0.9
  </code></pre>
  
  <p>now how do I tell git to get that specific version? Is there a terminal-command like:</p>
  
  <pre><code>git clone --mirror http://github.com/symfony/symfony.git --version=v2.0.9
  </code></pre>
  
  <p>Thanks in Advance</p>
