-// ScopedTypeRef<> is patterned after scoped_ptr<>, but maintains a ownership
-// of a reference to any type that is maintained by Retain and Release methods.
-//
-// The Traits structure must provide the Retain and Release methods for type T.
-// A default ScopedTypeRefTraits is used but not defined, and should be defined
-// for each type to use this interface. For example, an appropriate definition
-// of ScopedTypeRefTraits for CGLContextObj would be:
-//
-//   template<>
-//   struct ScopedTypeRefTraits<CGLContextObj> {
-//     void Retain(CGLContextObj object) { CGLContextRetain(object); }
-//     void Release(CGLContextObj object) { CGLContextRelease(object); }
-//   };
-//
-// For the many types that have pass-by-pointer create functions, the function
-// InitializeInto() is provided to allow direct initialization and assumption
-// of ownership of the object. For example, continuing to use the above
-// CGLContextObj specialization:
-//
-//   base::ScopedTypeRef<CGLContextObj> context;
-//   CGLCreateContext(pixel_format, share_group, context.InitializeInto());
-//
-// For initialization with an existing object, the caller may specify whether
-// the ScopedTypeRef<> being initialized is assuming the caller's existing
-// ownership of the object (and should not call Retain in initialization) or if
-// it should not assume this ownership and must create its own (by calling
-// Retain in initialization). This behavior is based on the |policy| parameter,
-// with |ASSUME| for the former and |RETAIN| for the latter. The default policy
-// is to |ASSUME|.
