See the file INSTALL for compilation and installation instructions for Unix.
+See the file NEWS for information on all that is new in this version
+of tar.
makefile.pc is a makefile for Turbo C 2.0 on MS-DOS.
There is no tar manual in this release. The old manual has too many
problems to make it usable. A new manual will appear in version 1.12.
-User-visible changes since 1.10:
-
-o Many bug fixes
-
-o Now uses GNU standard configure, generated by Autoconf.
-
-o Long options now use `--'; use of `+' is deprecated and support for it
- will eventually be removed.
-
-o New option --null causes filenames read by -T to be null-terminated,
- and causes -C to be ignored.
-
-o New option --remove-files deletes files (but not directories) after
- they are added to the archive.
-
-o New option --ignore-failed-read prevents read-errors from affecting
- the exit status.
-
-o New option --checkpoint prints occasional messages as the tape is
- being read or written.
-
-o New option --show-omitted-dirs prints the names of directories
- omitted from the archive.
-
-o Some tape drives which use a non-standard method of indicating
- end-of-tape now work correctly with multi-tape archives.
-
-o --volno-file: Read the volume number used in prompting the user (but
- not in recording volume ID's on the archive) from a file.
-
-o When using --multi-volume, you can now give multiple -f arguments;
- the various tape drives will get used in sequence and then wrap
- around to the beginning.
-
-o Remote archive names no longer have to be in /dev: any file with a
- `:' is interpreted as remote. If new option --force-local is given,
- then even archive files with a `:' are considered local.
-
-o New option --atime-preserve restores (if possible) atimes to their
- original values after dumping the file.
-
-o No longer does tar confusingly dump "." when you don't tell it what
- to dump.
-
-o When extracting directories, tar now correctly restores their
- modification and access times.
-
-o Longnames support is redone differently--long name info directly
- precedes the long-named file or link in the archive, so you no
- longer have to wait for the extract to hit the end of the tape for
- long names to work.
-
