title: IMAP and Gmail Labels
body: <p>I'm trying to figure out how to add GMail labels to my app. I'm using Mailcore that doesn't support it so I want to add them my self. I've researched a bit and found this:</p>
  
  <pre><code>a010 FETCH 1:4 (X-GM-LABELS)
  * 1 FETCH (X-GM-LABELS (\Inbox \Sent Important "Muy Importante"))
  * 2 FETCH (X-GM-LABELS (foo))
  * 3 FETCH (X-GM-LABELS ())
  * 4 FETCH (X-GM-LABELS (\Drafts))
  a010 OK FETCH (Success)
  </code></pre>

  <p>What languge is this? Is that an API? How do I access it?</p>
  
  <p>Thanks</p>
