title: svn problem. I can't add it because it's already in another SVN
body: <pre><code>svn add guess_language/
  svn: warning: 'guess_language' is already under version control
  </code></pre>
  
  <p>Why is this? When I downloaded it, it was under SVN. (I downloaded it from SVN)
  How do I release that svn...so that I can turn it into a regular directory?</p>
