title: Configure (or mimic) svn:externals to include code from Github in a svn-hosted project
body: <p>We use Subversion locally, and we're working on a project that uses a fork of Fluent NHibernate, which is hosted on Github.</p>
  
  <p>I'd like it set up so that a single svn checkout will retrieve everything necessary to build the project, but maintain the ability to fetch HEAD updates from github.</p>
  
  <p>Is there any way I can pull code from the Git repository as though it was an svn:external dependency? Can I just check the .git folder into our Subversion repository and just run git fetch when I need to, then svn commit the results?</p>
