+ *	File: kern/mach_header.h
+ *
+ *	Definitions for accessing mach-o headers.  This header wraps the
+ *	routines defined in osfmk/mach-o/mach_header.c; this is made clear
+ *	by the existance of the getsectcmdsymtabfromheader() prototype.
+ *
+ * NOTE:	The functions prototyped by this header only operate againt
+ *		32 bit mach headers.  Many of these functions imply the
+ *		currently running kernel, and cannot be used against mach
+ *		headers other than that of the currently running kernel.
+ *
+ * HISTORY
+ * 29-Jan-92  Mike DeMoney (mike@next.com)
+ *	Made into machine independent form from machdep/m68k/mach_header.h.
+ *	Ifdef'ed out most of this since I couldn't find any references.
