+//===-- NonCopyable.h - Disable copy ctor and op= in subclasses --*- C++ -*--=//
+//
+// This file defines the NonCopyable and NonCopyableV classes.  These mixin
+// classes may be used to mark a class not being copyable.  You should derive
+// from NonCopyable if you don't want to have a virtual dtor, or NonCopyableV
+// if you do want polymorphic behavior in your class.
+//
+// No library is required when using these functinons.
