title: How do I merge two SVN branches?
body: <p>I have two SVN branches checked out, "b1" and "b2". I would like to merge all of my commits from the "b1" branch onto the "b2" branch. I have tried something like</p>
  
  <pre><code>svn merge -r HEAD:HEAD b1 b2
  </code></pre>
  
  <p>but it does nothing. I am sure I have this command wrong, but I can't find good documentation on it. I would like to do this on the client side and not create a third branch.</p>
  
  <p>I am using SVN 1.4.4 which doesn't support the reintegrate option.</p>
  
  <p>How can I do it?</p>
