title: How can I put a Mac OS X .app under version control as one file?
body: <p>I am quite new to Git; I use SourceTree on Mac OS X.</p>
  
  <p>When I start tracking an <code>.app</code> file, Git treats it as multiple files inside the <code>.app</code> content.</p>
  
  <p>Is there any way to make another Git client only get that <code>.app</code> file as an application package rather than as multiple files?</p>
