SVN: list all branches of all projects in a respository
<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>
