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