- *     Definitions for accessing mach-o headers.
+ *    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.
