title: Git and pbxproj
body: <p>I was looking at an open source Mac application, and they gave some suggested values for .gitignore. They were what I would expect...</p>
  
  <p>However, they also suggested an entry into a .gitattributes file:</p>
  
  <p><code>*.pbxproj -crlf -diff -merge</code></p>
  
  <p>I'm not the most knowledgable in terms of git, so I was wondering - what exactly are the benefits of adding this line? What does do in particular? I've only seen this suggested in this <a href="http://pomodoro.ugolandini.com/pages/source.html" rel="noreferrer">one project</a>, and if it was normal practice I would have expected to see it elsewhere right now. So I was curious about how it applies to the pbxproj file specifically.</p>
