+// A macro to disallow the copy constructor and copy assignment functions.
+// This should be used in the private: declarations for a class.
+//
+// Use this macro instead of DISALLOW_COPY_AND_ASSIGN if you want to pass
+// ownership of the type through a base::Callback without heap-allocating it
+// into a scoped_ptr.  The class must define a move constructor and move
+// assignment operator to make this work.
+//
+// This version of the macro adds a Pass() function and a cryptic
+// MoveOnlyTypeForCPP03 typedef for the base::Callback implementation to use.
+// See IsMoveOnlyType template and its usage in base/callback_internal.h
+// for more details.
+// TODO(crbug.com/566182): Remove this macro and use DISALLOW_COPY_AND_ASSIGN
+// everywhere instead.
