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.  This distribution
also includes `rmt', the remote tape server.  The `mt' tape drive control
program is in the GNU `cpio' distribution.
