title: Can an SVN external pull down a Git repository's submodules?
body: <p>Since Github allows you to pull Git repositories down as SVN, I've included a Github repository as an external.</p>
  
  <ul>
  <li>trunk (svn:external <a href="https://github.com/Automattic/vip-quickstart" rel="nofollow">https://github.com/Automattic/vip-quickstart</a> base)</li>
  </ul>
  
  <p>... that works great. BUT that repository has its <em>own</em> submodules (see <a href="https://github.com/Automattic/vip-quickstart/tree/master/puppet/modules" rel="nofollow">https://github.com/Automattic/vip-quickstart/tree/master/puppet/modules</a>) and they aren't being downloaded on <code>svn update</code>.</p>
  
  <p>Can an SVN external pull down submodules? If so, how?</p>
