title: Checkout a specific older version of the source code through Subversion?
body: <p>My project is currently at release (that is, r1000), and that is what is checked out to my local repository.</p>
  
  <p>I would like to checkout a much older version to my repository, for purposes of performance comparison (for example, r500).</p>
  
  <p>I have taken my tests and gotten results with r1000.</p>
  
  <p>What svn commands do I need to use to get r500 into my local repository to run the same tests as on r1000?</p>
