title: SVN: list all branches of all projects in a respository
body: <p>I have SVN repository setup and it has somewhat around 15 different projects. Each project has a similar structure i.e. </p>
  
  <pre><code>ProjectOne/
            tags/
            branches/
            trunk/
  </code></pre>
  
  <p>now, what I want to do is somehow list all the branches for all the projects in the repository. 
  Is there a command or something I could use to do this? or going programmatically is the only option here ? </p>
