title: Git/SVN interop (preserving histories for both repositories)
body: <p>I'm developing a software module for an application, owned by a customer with SVN-based development process. Up to now, I have been used my own Git repository in doing so.</p>
  
  <p>Now, the module is mature enough to become part of the clients SVN tree. I did some git-svn based work in the past, but never with two initially independent repositories (the git part was always a clone taken from SVN). </p>
  
  <p>Is it possible to 'inject' a standalone git repository into a Subversion repository and let also his history become part of the SVN's repo? After that 'normal' work with git-svn on top of SVN should follow.</p>
