I'm a bit confused with this CL. Didn't we originally want to avoid this kind of
relative #include?

 
 @protocol CWVDelegate;
 @class CWVWebView;
 
 // Main interface for the CWV library.
 CWV_EXPORT
 @interface CWV : NSObject
 
 // Initializes the CWV library. This function should be called from
 // |application:didFinishLaunchingWithOptions:|.
 + (void)configureWithDelegate:(id<CWVDelegate>)delegate;
 
 // Shuts down the CWV library.  This function should be called from
 // |applicationwillTerminate:|.
 + (void)shutDown;
 
 // Creates and returns a web view.
 + (CWVWebView*)webViewWithFrame:(CGRect)frame;
 
 @end
 
 #endif  // IOS_WEB_VIEW_PUBLIC_CWV_H_
