GNU tar 1.20 (Release branch)

GNU `tar' saves many files together into a single tape or disk archive, and can restore individual files from the archive. It includes multivolume support, the ability to archive sparse files, automatic archive compression/decompression, remote archives and special features that allow `tar' to be used for incremental and full backups. It also includes `rmt', the remote tape server (the `mt' tape drive control program is in GNU `cpio'). License: GNU General Public License (GPL) Changes:
This release has new options: -a (selects a compression algorithm basing on the suffix of the archive file name), --lzma (selects the LZMA compression algorithm), and --hard-dereference, which dereferences hard links during archive creation and stores the files they refer to (instead of creating the usual hard link members).
