title: Replicating svn:externals into a git repository (Referencing git from Subversion)
body: <p>We have a Subversion repository that is not going to move to git in the short to medium term, but I would like to use a DVCS for controlling and versioning 3rd party libraries.</p>
  
  <p>Is there a way of using something like svn:externals to fetch/link a revision from git, driven by the Subversion checkout?</p>
