title: Can I move the .git directory for a repo to it's parent directory?
body: <p>I have two sub-directories each with a repo, thus :</p>
  
  <pre><code>PPP/
   |--ABC/
   |   |--.git/
   |   |--AAA/
   |   |    BBB/
   |   |   CCC/
   |   
   |--DEF/
   |   |--.git/
   |   |--DDD/
   |   |--EEE/
  </code></pre>
  
  <p>And would like to combine them into one repo, so, I would assume the directory structure would be like this:</p>
  
  <pre><code>PPP/
   |--.git/
   |--ABC/
   |   |--AAA/
   |   |--BBB/
   |   |--CCC/
   |   
   |--DEF/
   |   |--DDD/
   |   |--EEE/
  </code></pre>
  
  <p>Is this posible?</p>
  
  <p>Also currently several people have the repos on their machines. How much more complicated does that make life?</p>
