-Native byte order is big-endian or little-endian, depending on the host system.
-For example, Motorola and Sun processors are big-endian; Intel and DEC

+Native byte order is big-endian or little-endian, depending on the host
+system. For example, Intel x86 and AMD64 (x86-64) are little-endian;
+Motorola 68000 and PowerPC G5 are big-endian; ARM and DEC Alpha feature
+switchable endianness (bi-endian). Use sys.byteorder to check the
+endianess of your system.
 
 Native size and alignment are determined using the C compiler's
 ``sizeof`` expression.  This is always combined with native byte order.
