title: How can I delete all unversioned/ignored files/folders in my working copy?
body: <p>If I have a working copy of a Subversion repository, is there a way to delete all unversioned or ignored files in that working copy with a single command or tool?  Essentially, I'm looking for the SVN analogue to <a href="http://www.kernel.org/pub/software/scm/git/docs/git-clean.html" rel="noreferrer"><code>git clean</code></a>.</p>
  
  <p>Either a command line or GUI solution (for TortoiseSVN) would be acceptable.</p>
