title: Syncing SVN to Mercurial using svnsync & hg convert -- misses svn:externals?
body: <p>I've created a Mercurial mirror of an SVN repository (using this tutorial: <a href="http://oreilly.com/opensource/excerpts/opensource-mercurial/migrating-to-mercurial.html" rel="nofollow">http://oreilly.com/opensource/excerpts/opensource-mercurial/migrating-to-mercurial.html</a>). The sync works great, except I've noticed it's not picking up an external repository that is referenced in the main SVN repo...</p>
  
  <p>I'd ideally like to be able to pull everything as a single repo into Mercurial (along with changesets if possible).</p>
  
  <p>What I'm not sure of is: is the missing external a limitation of svnsync, or a limitation of hg convert?</p>
  
  <p>Is there any way I can force the external to be synced as well, into the same Mercurial repo?</p>

  <p>I'm thinking a good solution would be to set up the sync process all over again, for the external.
  Create a fork of the current hg mirror, and sync the external into the hg mirror fork.</p>
  
  <p>The catch with that is, the external's trunk is intended to go into a subfolder of the first mirror, so how can I replicate that with convert? I doubt I could tell convert to import into a subfolder...</p>
