title: how do I package support files in a cocoa app
body: <p>I'm building an application where I want to provide the user with a few dozen templates that will internally take the form of property lists. I would also want to group them in categories, which would conveniently be achieved using folders.</p>
  
  <p>While I have contemplated shipping these files as simple resources in my application, I don't like the idea of this single location containing dozens and dozens of files, and besides it doesn't seem to be possible to group them in folders.</p>
  
  <p>I can see that many applications have installed such resources in their application support directory (~/Library/Application Support//...), but I can't seem  to find any documentation resource on how to achieve this.</p>
