 This library is for working with "'.tar'" archive files. It can read and write
-a range of common variations of archive format including V7, USTAR, POSIX and
-GNU formats. It provides support for packing and unpacking portable archives.
-This makes it suitable for distribution but not backup because details like
-file ownership and exact permissions are not preserved.
