title: What is the convention for git local repository directory structure
body: <p>Here is my git directory structure</p>
  
  <pre><code>~/git/ProjectA/.git
  ~/git/ProjectA/ProjectA
  ~/git/ProjectB/.git
  ~/git/ProjectB/ProjectB
  </code></pre>
  
  <p>Is that the convention or is it more preferable to do something like?</p>
  
  <pre><code>~/git/myRepo/.git
  ~/git/myRepo/ProjectA
  ~/git/myRepo/ProjectB
  </code></pre>
  
  <p>or</p>
  
  <pre><code>~/git/.git
  ~/git/ProjectA
  ~/git/ProjectB
  </code></pre>
  
  <p>or something else entirely?</p>
