title: NetworkExtension - NEVPNManager
body: <p>Apple published with iOS 8 a new Framework "NetworkExtension".</p>
  
  <p>I want to start a VPN Connection out of an app with the NEVPNManager, or has this Framework another use?</p>
  
  <p>Has somebody information or an example about this Framework?
  I can´t find information about it on the developer.apple.com website, only in the header files.</p>
  
  <p>Thanks</p>
