+GNU 'tar' is derived from John Gilmore's public domain 'tar'.
+
+See file 'ABOUT-NLS' for how to customize this program to your language.
+See file 'COPYING' for copying conditions.
+See file 'INSTALL' for compilation and installation instructions.
+See file 'NEWS' for a list of major changes in the current release.
+See file 'THANKS' for a list of contributors.
+
+Besides those configure options documented in files 'INSTALL' and
+'ABOUT-NLS', an extra option may be accepted after './configure':
+
+* Install
+
+** Selecting the default archive format.
+
+The default archive format is GNU, this can be overridden by
+presetting DEFAULT_ARCHIVE_FORMAT while configuring. The allowed
+values are GNU, V7, OLDGNU, USTAR and POSIX.
+
+** Selecting the default archive device
+
+The default archive device is now 'stdin' on read and 'stdout' on write.
+The installer can still override this by presetting 'DEFAULT_ARCHIVE'
+in the environment before configuring (the behavior of '-[0-7]' or
+'-[0-7]lmh' options in 'tar' are then derived automatically). Similarly,
+'DEFAULT_BLOCKING' can be preset to something else than 20.
+
+** Selecting full pathname of the "rmt" binary.
+
+Previous versions of tar always looked for "rmt" binary in the
+directory "/etc/rmt". However, the "rmt" program included
+in the distribution was installed under "$prefix/libexec/rmt".
+To fix this discrepancy, tar now looks for "$prefix/libexec/rmt".
+If you do not want this behavior, specify full path name of
+"rmt" binary using DEFAULT_RMT_DIR variable, e.g.:
+
+./configure DEFAULT_RMT_DIR=/etc
+
+If you already have a copy of "rmt" installed and wish to use it
+instead of the version supplied with the distribution, use --with-rmt
+option:
+
+./configure --with-rmt=/etc/rmt
+
+This will also disable building the included version of rmt.
+
+** Installing backup scripts.
+
+This version of tar is shipped with the shell scripts for producing
+incremental backups (dumps) and restoring filesystems from them.
+The name of the backup script is "backup". The name of the
+restore script is "restore". They are installed in "$prefix/sbin"
+directory.
+
+Use option --enable-backup-scripts to compile and install these
+scripts.
+
+** '--disable-largefile' omits support for large files, even if the
+operating system supports large files. Typically, large files are
+those larger than 2 GB on a 32-bit host.
