title: Is there a way to include submodules in GitHub download
body: <p>I am using git submodules extensively in my projects, eg. when I use some library that is located in different repository, instead of copy pasting the code from library, I just add git submodule (reference to that repository itself).</p>
  
  <p>The problem I am facing with this is that if you download the zip file using GitHub's download feature, the submodules are not part of a download. There are just empty folders and my program doesn't compile.</p>
  
  <p>Is there any way to get GitHub to include submodules in the zip file?</p>
