         -ASi Unix Extra Field:
          ====================

          The following is the layout of the ASi extra block for Unix.  The
          local-header and central-header versions are identical.
          (Last Revision 19960916)

          Value         Size        Description
          -----         ----        -----------
  (Unix3) 0x756e        Short       tag for this extra block type ("nu")
          TSize         Short       total data size for this block
          CRC           Long        CRC-32 of the remaining data
          Mode          Short       file permissions
          SizDev        Long        symlink'd size OR major/minor dev num
          UID           Short       user ID
          GID           Short       group ID
          (var.)        variable    symbolic link filename

          Mode is the standard Unix st_mode field from struct stat, containing
          user/group/other permissions, setuid/setgid and symlink info, etc.

          If Mode indicates that this file is a symbolic link, SizDev is the
          size of the file to which the link points.  Otherwise, if the file
          is a device, SizDev contains the standard Unix st_rdev field from
          struct stat (includes the major and minor numbers of the device).
          SizDev is undefined in other cases.

          If Mode indicates that the file is a symbolic link, the final field
          will be the name of the file to which the link points.  The file-
          name length can be inferred from TSize.

          [Note that TSize may incorrectly refer to the data size not counting
           the CRC; i.e., it may be four bytes too small.]
