title: Where is documentation for the iTunes API on OS X?
body: <p>I'm trying to find an API to control iTunes on OS X.  I found the following:</p>
  
  <p><a href="http://developer.apple.com/sdk/itunescomsdk.html" rel="noreferrer">http://developer.apple.com/sdk/itunescomsdk.html</a></p>
  
  <p>I imagine on OS X, what I need is built in, but I have no idea where the API is documented?</p>
  
  <p>Thanks in advance for any help.</p>
