title: GIT checking out code from output of "git describe"
body: <p>I am thinking about using <code>git describe</code> to generate automated version numbers. As suggest <a href="https://stackoverflow.com/questions/4120001/what-is-the-git-equivalent-for-revision-number">here</a>. </p>
  
  <p>My question is that if I get o/p of <code>git describe</code> as <code>v2.0-64-g835c907</code>,
  how can I checkout that particular revision number using git in future?</p>
