+ *     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.
