+ * This file is a modified version of 'a.out.h'.  It is to be used in all GNU
+ * tools modified to support the i80960 b.out format (or tools that operate on
+ * object files created by such tools).
+ *
+ * All i80960 development is done in a CROSS-DEVELOPMENT environment.  I.e.,
+ * object code is generated on, and executed under the direction of a symbolic
+ * debugger running on, a host system.  We do not want to be subject to the
+ * vagaries of which host it is or whether it supports COFF or a.out format, or
+ * anything else.  We DO want to:
+ *
+ *	o always generate the same format object files, regardless of host.
+ *
+ *	o have an 'a.out' header that we can modify for our own purposes
+ *	  (the 80960 is typically an embedded processor and may require
+ *	  enhanced linker support that the normal a.out.h header can't
+ *	  accommodate).
+ *
+ * As for byte-ordering, the following rules apply:
+ *
+ *	o Text and data that is actually downloaded to the target is always
+ *	  in i80960 (little-endian) order.
+ *
+ *	o All other numbers (in the header, symbols, relocation directives)
+ *	  are in host byte-order:  object files CANNOT be lifted from a
+ *	  little-end host and used on a big-endian (or vice versa) without
+ *	  modification.
+ *
+ *	o The downloader ('comm960') takes care to generate a pseudo-header
+ *	  with correct (i80960) byte-ordering before shipping text and data
+ *	  off to the NINDY monitor in the target systems.  Symbols and
+ *	  relocation info are never sent to the target.
