The old rpl file format

Kept for backward compatibility 4/26/2002

The rpl file for Lispix 02* was a LISP assoc list, saved as a text file.

Lispix 04n and beyond also accepts this format for backward compatibility, but will not write this format.

Examples:

((MLX::WIDTH 512) (MLX::HEIGHT 512) (MLX::DEPTH 8) (MLX::OFFSET 0)
(MLX::DATA-TYPE :UNSIGNED) (MLX::DATA-LENGTH 1)
(MLX::BYTE-ORDER :DONT-CARE) (MLX::RECORD-BY :IMAGE))
---------

((WIDTH 200) (HEIGHT 150) (DEPTH 256) (OFFSET 0) (PIXEL-TYPE :VECTOR) (DATA-TYPE :UNSIGNED) (DATA-LENGTH 1) (BYTE-ORDER :DONT-CARE) (RECORD-BY :VECTOR))

---------

((:WIDTH 240) (:HEIGHT 320) (:DEPTH 1) (:OFFSET 0)
(:DATA-TYPE :UNSIGNED) (:DATA-LENGTH 1) (:BYTE-ORDER :DONT-CARE)
(:RECORD-BY :DONT-CARE))
