+ * This is a Xenix style hex dump command.
+ *
+ * The 'reverse hex dump' option is an addition that allows a simple 
+ * method of editing binary files.
+ *
+ * The overkill Linux 'hexdump' command can be configured to generate
+ * the same format as this command by this shell macro:
+ *
+ * hd() { hexdump -e '"%06.6_ax:" 8/1 " %02x" " " 8/1 " %02x" "  " ' \
+ *                -e '16/1 "%_p" "\n"' \
+ *                "$@"
+ *      }
