     * Firmware and Cronus.
     *
     * These files contain :
     *  1) Target lines
     *     a) System Target line - associated attribute applies to
     *                              entire system
     *     b) Unit Target line - associated attribute applies only to
     *                            explicitly identified Unit
     *  2) Attribute Lines  (associated with the most recent target line)
     *
     * ---------------------------------------
     * The format of a System Target Line is :
