title: SVN - delete a revision, or make an older revision the head
body: <p>I'm fairly new to SVN and I've never had to revert back to a previous revision, although I can get a copy of a revision from the repository okay.  I'm using TortoiseSVN and the Visual Studio SVN plugin.</p>
  
  <p>I'd like to restore the trunk back to a previous revision.</p>
  
  <p>How can I restore the trunk - e.g. rollback to a previous revision and make this the head?</p>
  
  <p>thanks</p>
