//===-- 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.
