29 * Background: Original tar file format did not use its linkflag to
30 * specify directories. Instead regular files simply have a slash
31 * appended to their names. No data blocks follow directories in
32 * archives. This means that a possibly specified file size must not
33 * be used to determine the amount of data blocks to skip.
