UNAR6: reconstructing the AR6 archive format

UNAR6 reconstructs the AR6 archive format used by the Manažer M602 DOS file manager from observed archives. Its format notes specify record headers, directory entries, checksums and PKWARE DCL compression, while C, Pascal and Python implementations list, test and extract archive contents.
