27  * sys/note.h:	interface for annotating source with info for tools
28  *
29  * This is the underlying interface; NOTE (/usr/include/note.h) is the
30  * preferred interface, but all exported header files should include this
31  * file directly and use _NOTE so as not to take "NOTE" from the user's
32  * namespace.  For consistency, *all* kernel source should use _NOTE.
33  *
34  * By default, annotations expand to nothing.  This file implements
35  * that.  Tools using annotations will interpose a different version
36  * of this file that will expand annotations as needed.
