title: How do I share code between 2 (or more) AppHarbor sites?
body: <p>I currently have two git repos and two sites deployed on AppHarbor. All works fine. Problem is that both sites share quite a few things between them and it is a pain to duplicate the work between them and ensure that they are up to date.</p>
  
  <p>What would be ideal is having a single git repo with two VS solutions. One for each site. Then I could extract the common elements and share the code between the different sites.</p>
  
  <p>Is there a way to tell AppHarbor to use a specific solution file? And share a git repo between two sites?</p>
  
  <p>Is there some other way that works?</p>
