title: Git: How to handle git libraries in project
body: <p>I've a Xcode project which itself has Git Source Control. In a <em>Libraries</em> folder I've cloned eight other Git project from <a href="https://github.com/">GitHub</a>. They are located inside my own Git repository and I've added all these libraries to my git in a commit.</p>
  
  <p>Instead of having the code of all these git libraries in my repository, is there a way to let git download their code from their repo when I make a clone of my repo? Or is it normal to include other git repos inside a project?</p>
