9 version 1.15.2 (CVS version -- unreleased)
13 * Any number of -T (--files-from) options may be used in the command line.
14 The file specified with -T may include any valid `tar' options,
15 including another -T option.
16 Compatibility note: older versions of tar would only recognize -C
17 as an option name within the file list file. Now any file whose name
18 starts with - is handled as an option. To insert file names starting with
19 dash, use the --add-file option.
21 * List files containing null-separated file names are detected and processed
22 automatically. It is no longer necessary to give the --null option.
24 * New option --no-unquote disables the unquoting of input file names.
25 This is useful for processing output from `find dir -print0'.
26 An orthogonal option --unquote is provided as well.
28 * New option --test-label tests the archive volume label.
29 If an argument is specified, the label is compared against its value.
30 Tar exits with code 0 if the two strings match, and with code 2 if
33 If no argument is given, the --verbose option is implied. In this case,
34 tar prints the label name if present and exits with code 0.
36 * New option --show-stored-names. When creating an archive in verbose mode,
37 it lists member names as stored in the archive, i.e., with any eventual
38 prefixes removed. The option is useful, for example, while comparing
39 `tar cv' and `tar tv' outputs.
41 * Better support for full-resolution time stamps. Tar cannot restore
42 time stamps to full nanosecond resolution, though, until the kernel
43 guys get their act together and give us a system call to set file time
44 stamps to nanosecond resolution.
46 * The -v option now prints time stamps only to 1-minute resolution,
47 not full resolution, to avoid using up too many output columns.
48 Nanosecond resolution is now supported, but that would be too much.
52 ** Allow non-option arguments to be interspersed with options.
53 ** When extracting or listing archives in old GNU format, tar
54 used to read an extra block of data after a long name header
55 if length of the member name was divisible by block size (512).
56 Consequently, the file pointer was set off and the next member
57 was not processed correctly.
58 ** Previous version created invalid archives when files shrink
60 ** Compare mode (tar d) hanged when trying to compare file contents.
63 version 1.15.1 - Sergey Poznyakoff, 2004-12-21
65 This version fixes a bug introduced in 1.15 which caused
66 tar to refuse to extract files from standard input.
69 version 1.15 - Sergey Poznyakoff, 2004-12-20
71 * Compressed archives are recognised automatically, it is no longer
72 necessary to specify -Z, -z, or -j options to read them. Thus, you can
73 now run `tar tf archive.tar.gz'.
75 * When restoring incremental dumps, --one-file-system option
76 prevents directory hierarchies residing on different devices
79 With the previous versions of tar it was dangerous to create
80 incremental dumps with --one-file-system option, since they
81 would recursively remove mount points when restoring from the
82 back up. This change fixes the bug.
84 * Renamed --strip-path to --strip-components for consistency with
87 * Skipping archive members is sped up if the archive media supports
90 * Restore script starts restoring only if it is given --all (-a) option,
91 or some patterns. This is to prevent accidental restores.
93 * `tar --verify' prints a warning if during archive creation some of
94 the file names had their prefixes stripped off.
96 * New option --exclude-caches instructs tar to exclude cache directories
97 automatically on archive creation. Cache directories are those
98 containing a standardized tag file, as specified at:
100 http://www.brynosaurus.com/cachedir/spec.html
102 * New configure option --with-rmt allows to specify full path name to
103 the `rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
104 introduced in version 1.14
106 * New configure variable DEFAULT_RMT_DIR allows to specify the directory
107 where to install `rmt' utility. This is necessary since modifying
108 --libexecdir as was suggested for version 1.14 produced a side effect: it
109 also modified installation prefix for backup scripts (if
110 --enable-backup-scripts was given).
113 ** Fixed flow in recognizing files to be included in incremental dumps.
114 ** Correctly recognize sparse archive members when used with -T option.
115 ** GNU multivolume headers cannot store filenames longer than 100 characters.
116 Do not allow multivolume archives to begin with such filenames.
117 ** If a member with link count > 2 was stored in the archive twice,
118 previous versions of tar were not able to extract it, since they
119 were trying to link the file to itself, which always failed and
120 lead to removing the already extracted copy. Preserve the first
121 extracted copy in such cases.
122 ** Restore script was passing improper argument to tar --listed option (which
123 didn't affect the functionality, but was logically incorrect).
124 ** Fixed verification of created archives.
125 ** Fixed unquoting of file names containing backslash escapes (previous
126 versions failed to recognize \a and \v).
127 ** When attempting to delete a non-existing member from the archive, previous
128 versions of tar used to overwrite last archive block with zeroes.
131 version 1.14 - Sergey Poznyakoff, 2004-05-11
133 * Added support for POSIX.1-2001 and ustar archive formats.
134 * New option --format allows to select the output archive format
135 * The default output format can be selected at configuration time
136 by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
137 Allowed values are GNU, V7, OLDGNU and POSIX.
138 * New option --strip-path allows to cut off a given number of
139 path elements from the name of the file being extracted.
141 * New options --index-file, --no-overwrite-dir. The --overwrite-dir
142 option is now the default; use --no-overwrite-dir if you prefer
143 the previous default behavior.
145 * The semantics of -o option is changed. When extracting, it
146 does the same as --no-same-owner GNU tar option. This is compatible
147 with UNIX98 tar. Otherwise, its effect is the same as that of
148 --old-archive option. This latter is deprecated and will be removed
151 * New option --check-links prints a message if not all links are dumped
152 for a file being archived. This corresponds to the UNIX98 -l option.
153 The current semantics of the -l option is retained for compatibility
154 with previous releases, however such usage is strongly deprecated as
155 the option will change to its UNIX98 semantics in the future releases.
157 * New option --occurrence[=N] can be used in conjunction with one of
158 the subcommands --delete, --diff, --extract or --list when a list of
159 files is given either on the command line or via -T option. This
160 option instructs tar to process only the Nth occurrence of each named
161 file. N defaults to 1, so `tar -x -f archive --occurrence filename'
162 extracts the first occurrence of `filename' from `archive'
163 and terminates without scanning to the end of the archive.
165 * New option --pax-option allows to control the handling of POSIX
166 keywords in `pax' extended headers. It is equivalent to `pax'
169 * --incremental and --listed-incremental options work correctly on
170 individual files, as well as on directories.
172 * New scripts: backup (replaces old level-0 and level-1) and restore.
173 The scripts are compiled and installed if --enable-backup-scripts
174 option is given to configure.
176 * By default tar searches "rmt" utility in "$prefix/libexec/rmt",
177 which is consistent with the location where the version of "rmt"
178 included in the package is installed. Previous versions of tar
179 used "/etc/rmt". To install "rmt" to its traditional location,
180 run configure with option --libexecdir=/etc. Otherwise, if you
181 already have rmt installed and wish to use it, instead of the
182 shipped in version, set the variable DEFAULT_RMT_COMMAND to
183 the full path name of the utility, e.g., ./configure
184 DEFAULT_RMT_COMMAND=/etc/rmt.
186 Notice also that the full path name of the "rmt" utility to
187 use can be set at runtime, by giving option --rmt-command to
190 * Removed obsolete command line options:
191 ** --absolute-paths superseded by --absolute-names
192 ** --block-compress is not needed any longer
193 ** --block-size superseded by --blocking-factor
194 ** --modification-time superseded by --touch
195 ** --read-full-blocks superseded by --read-full-records
196 ** --record-number superseded by --block-number
197 ** --version-control superseded by --backup
199 * New message translations fi (Finnish), gl (Galician), hr (Croatian),
200 hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
201 (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
202 The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
207 version 1.13.25 - Paul Eggert, 2001-09-26
212 version 1.13.24 - Paul Eggert, 2001-09-22
214 * New option --overwrite-dir.
215 * Fixes for buffer overrun, porting, and copyright notice problems.
216 * The message translations for Korean are available again.
219 version 1.13.23 - Paul Eggert, 2001-09-13
221 * Bug, porting, and copyright notice fixes.
224 version 1.13.22 - Paul Eggert, 2001-08-29
229 version 1.13.21 - Paul Eggert, 2001-08-28
231 * Porting and copyright notice fixes.
234 version 1.13.20 - Paul Eggert, 2001-08-27
236 * Some bugs were fixed:
238 - hard links to symbolic links
240 * New option --recursion (the default) that is the inverse of --no-recursion.
242 * New options --anchored, --ignore-case, --wildcards,
243 --wildcards-match-slash, and their negations (e.g., --no-anchored).
244 Along with --recursion and --no-recursion, these options control how
245 exclude patterns are interpreted.
247 * The default interpretation of exclude patterns is now --no-anchored
248 --no-ignore-case --recursion --wildcards --wildcards-match-slash.
249 This is a quiet change to the semantics of --exclude. The previous
250 semantics were a failed attempt at backward compatibility but it
251 became clear that the semantics were puzzling and did not satisfy
252 everybody. Rather than continue to try to revive that dead horse we
253 thought it better to substitute cleaner semantics, with options so
254 that you can change the behavior more to your liking.
256 * New message translations for Indonesian and Turkish.
257 The translation for Korean has been withdrawn due to encoding errors.
258 It will be reissued once those are fixed.
261 version 1.13.19 - Paul Eggert, 2001-01-13
263 * The -I option has been withdrawn, as it was buggy and confusing.
264 Eventually it is planned to be reintroduced, with the same meaning as -T.
266 * With an option like -N DATE, if DATE starts with "/" or ".", it is taken
267 to be a file name; the last-modified time of that file is used as the date.
270 version 1.13.18 - Paul Eggert, 2000-10-29
272 * Some security problems have been fixed. `tar -x' now modifies only
273 files under the working directory, unless you also specify an unsafe
274 option like --absolute-names or --overwrite.
276 * The short name of the --bzip option has been changed to -j,
277 and -I is now an alias for -T, for compatibility with Solaris tar.
279 * The manual is now distributed under the GNU Free Documentation License.
281 * The new environment variable TAR_OPTIONS holds default command-line options.
283 * The --no-recursion option now affects extraction too.
285 * The wording in some diagnostics has been changed slightly.
287 * Snapshot files now record whether each file was accessed via NFS.
288 The new file format is upward- and downward-compatible with the old.
290 * New language supported: da.
292 * Compilation by traditional (K&R) C compilers is no longer supported.
293 If you still use such a compiler, please use GCC instead.
295 * This version of tar works best with GNU gzip test version 1.3 or later.
296 Please see <ftp://alpha.gnu.org/gnu/gzip/>.
298 * `tar --delete -f -' now works again.
301 version 1.13.17 - Paul Eggert, 2000-01-07.
303 * `tar --delete -f -' is no longer allowed; it was too buggy.
304 * Diagnostic messages have been made more regular and consistent.
307 version 1.13.16 - Paul Eggert, 1999-12-13.
309 * By default, tar now refuses to overwrite an existing file when
310 extracting files from an archive; instead, it removes the file
311 before extracting it. If the existing file is a symbolic link, the
312 link is removed and not the pointed-to file. There is one
313 exception: existing nonempty directories are not removed, nor are
314 their ownerships or permissions extracted. This fixes some
315 longstanding security problems.
317 The new --overwrite option enables the old default behavior.
319 For regular files, tar implements this change by using the O_EXCL
320 option of `open' to ensure that it creates the file; if this fails, it
321 removes the file and tries again. This is similar to the behavior of
322 the --unlink-first option, but it is faster in the common case of
323 extracting a new directory.
325 * By default, tar now ignores file names containing a component of `..'
326 when extracting, and warns about such file names when creating an archive.
327 To enable the old behavior, use the -P or --absolute-names option.
329 * Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
330 correctly. It relies on the mbrtowc function to handle multibyte characters.
332 * The file generated by -g or --listed-incremental now uses a format
333 that is independent of locale, so that users need not worry about
334 locale when restoring a backup. This is needed for proper support
335 of multibyte characters. Old-format files can still be read, and
336 older versions of GNU tar can read new-format files, unless member
337 names have multibyte chars.
339 * Many diagnostics have been changed slightly, so that file names are
340 now output unambiguously. File names in diagnostics now are either
341 `quoted like this' (in the default C locale) or are followed by
342 colon, newline, or space, depending on context. Unprintable
343 characters are escaped with a C-like backslash conventions.
344 Terminating characters (e.g., close-quote, colon, newline)
345 are also escaped as needed.
347 * tar now ignores socket files when creating an archive.
348 Previously tar archived sockets as fifos, which caused problems.
351 version 1.13.15 - Paul Eggert, 1999-12-03.
353 * If a file's ctime changes when being archived, report an error.
354 Previously tar looked at mtime, which missed some errors.
357 version 1.13.14 - Paul Eggert, 1999-11-07.
359 * New translations ja, pt_BR.
360 * New options --help and --version for rmt.
361 * Ignore Solaris door files when creating an archive.
364 version 1.13.13 - Paul Eggert, 1999-10-11.
366 * Invalid headers in tar files now elicit errors, not just warnings.
367 * `tar --version' output conforms to the latest GNU coding standards.
368 * If you specify an invalid date, `tar' now substitutes (time_t) -1.
369 * `configure --with-dmalloc' is no longer available.
372 version 1.13.12 - Paul Eggert, 1999-09-24.
374 * `tar' now supports hard links to symbolic links.
376 * New options --no-same-owner, --no-same-permissions.
378 * --total now also outputs a human-readable size, and a throughput value.
380 * `tar' now uses two's-complement base-256 when outputting header
381 values that are out of the range of the standard unsigned base-8
382 format. This affects archive members with negative or huge time
383 stamps or uids, and archive members 8 GB or larger. The new tar
384 archives cannot be read by traditional tar, or by older versions of
385 GNU tar. Use the --old-archive option to revert to the old
386 behavior, which uses unportable representations for negative values,
387 and which rejects large files.
389 * On 32-bit hosts, `tar' now assumes that an incoming time stamp T in
390 the range 2**31 <= T < 2**32 represents the negative time (T -
391 2**32). This behavior is nonstandard and is not portable to 64-bit
392 time_t hosts, so `tar' issues a warning.
394 * `tar' no longer gives up extracting immediately upon discovering
395 that an archive contains garbage at the end. It attempts to extract
396 as many files as possible from the good data before the garbage.
398 * A read error now causes a nonzero exit status, not just a warning.
400 * Some diagnostics have been reworded for consistency.
403 version 1.13.11 - Paul Eggert, 1999-08-23.
405 * The short name of the --bzip option has been changed to -I,
406 for compatibility with paxutils.
408 * -T /dev/null now matches nothing; previously, it matched anything
409 if no explicit operands were given.
411 * The `--' option now works the same as with other GNU utilities;
412 it causes later operands to be interpreted as file names, not options,
413 even if they begin with `-'.
415 * For the --newer and --after-date options, the table of time zone
416 abbreviations like `EST' has been updated to match current practice.
417 Also, local time abbreviations are now recognized, even if they are
418 not in tar's hardwired table. Remember, though, that you should use
419 numeric UTC offsets like `-0500' instead of abbreviations like
420 `EST', as abbreviations are not standardized and are ambiguous.
423 version 1.13.10 - Paul Eggert, 1999-08-20.
425 * `tar' now uses signed base-64 when outputting header values that are
426 out of the range of the standard unsigned base-8 format. [This
427 change was superseded in 1.13.12, described above.]
430 version 1.13.9 - Paul Eggert, 1999-08-18.
432 * `tar' now writes two zero blocks at end-of-archive instead of just one.
433 POSIX.1 requires this, and some other `tar' implementations check for it.
435 * `tar' no longer silently accepts a block containing nonzero checksum bytes
438 * `tar' now reads buggy tar files that have a null byte at the start of a
439 numeric header field.
442 version 1.13.8 - Paul Eggert, 1999-08-16.
444 * For compatibility with traditional `tar', intermediate directories
445 created automatically by root are no longer given the uid and gid of
446 the original file or directory.
449 version 1.13.7 - Paul Eggert, 1999-08-14.
451 * --listed-incremental and --newer are now incompatible options.
453 * When creating an archive, leading `./' is no longer stripped,
454 to match traditional tar's behavior (and simplify the documentation).
456 * --diff without --absolute-names no longer falls back on absolute names.
459 version 1.13.6 - Paul Eggert, 1999-08-11.
461 * An --exclude pattern containing / now excludes a file only if it matches an
462 initial prefix of the file name; a pattern without / continues to
463 exclude a file if it matches any file name component.
465 * The protocol for talking to rmt has been extended slightly.
466 Open flags are now communicated in symbolic format as well as numeric.
467 The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
468 when rmt is operating on a different operating system from tar.
469 The numeric format is retained, and rmt uses it if symbolic format is absent,
470 for backward compatibility with older versions of tar and rmt.
472 * When writing GNU tar format headers, tar now uses signed base-64
473 for values that cannot be represented in unsigned octal.
474 This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
475 larger uids, negative time stamps, etc.
477 * When extracting files with unknown ownership, tar now looks up the
478 uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
479 and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
481 * tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
483 * New option -y or --bzip2 for bzip2 compression, by popular request.
486 version 1.13.5 - Paul Eggert, 1999-07-20.
488 * Do the delayed updates of file metadata even after a fatal error.
491 version 1.13.4 - Paul Eggert, 1999-07-20.
493 * Do not chmod unless we are root or the -p option was given;
494 this matches historical practice.
497 version 1.13.3 - Paul Eggert, 1999-07-16.
499 * A path name is excluded if any of its file name components matches an
500 excluded pattern, even if the path name was specified on the command line.
501 Also see 1.13.6 for later changes in this area.
504 version 1.13.2 - Paul Eggert, 1999-07-14.
506 * Bug reporting address changed to <bug-tar@gnu.org>.
509 version 1.13.1 - Paul Eggert, 1999-07-12.
513 version 1.13 - Paul Eggert, 1999-07-08.
515 * Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
516 Also, support for larger uids, device ids, etc.
517 * Many bug fixes and porting fixes.
518 * This release is only for fixes. A more ambitious test release,
519 with new features, is available as part of the paxutils. Please see:
520 ftp://alpha.gnu.org/gnu/paxutils/
521 The fixes in this release are intended to be merged with paxutils
522 at some point, but they haven't been merged yet.
523 * An interim GNU tar alpha had new --bzip2 and --ending-file options,
524 but they have been removed to maintain compatibility with paxutils.
525 Please try --use=bzip2 instead of --bzip2.
527 Version 1.12 - François Pinard, 1997-04.
530 * Use shell globbing patterns for --label, instead of regular expressions.
531 * Do not quote anymore internally over the quoting done by the shell.
534 * Offer internationalization capabilities of most recent GNU gettext.
535 * Messages available in many more languages, thanks to all translators!
536 * Usage of ISO 8601 dates in listings, instead of local American dates.
537 * More normalization and cleanup in error messages.
540 * For helping using tar with find, offer a --no-recursion option.
541 * Implement --numeric-owner for ignoring symbolic names at create time.
542 * New --owner, --group --mode options, still preliminary.
543 * Recognize creating an archive on /dev/null, so Amanda works faster.
544 * Object to the creation of an empty archive (like in `tar cf FILE').
545 * Barely start implementing --posix and POSIXLY_CORRECT.
548 * Make a better job at restoring file and directory attributes.
549 * Automatically attempt deleting existing files when in the way.
550 * Option --unlink-first (-U) removes most files prior to extraction.
551 * Option --recursive-unlink removes non-empty directories when in the way.
552 * Option --numeric-owner ignores owner/group names, it uses UID/GID instead.
553 * Use global umask when creating missing intermediate directories.
554 * When symlinks are not available, extract symbolic links as hard links.
555 * Diagnose extraction of contiguous files as regular files.
556 * New --backup, --suffix and --version-control options.
559 * Better support of huge archives with --tape-length and --totals.
560 * Rename option --read-full-blocks (-B) to --read-full-records (-B).
561 * Rename option --block-size (-b) to --blocking-factor (-b).
562 * Rename option --record-number (-R) to --block-number (-R).
563 * With --block-number (-R), report null blocks and end of file.
564 * Implement --record-size for introducing a size in bytes.
565 * Delete --block-compress option and rather decide it automatically.
566 * Rename option --modification-time to --touch.
568 Many bugs are squashed, while others still run free.
570 Version 1.11.8 - François Pinard, 1995-06.
572 * Messages available in French, German, Portuguese and Swedish.
573 * The distribution provides a rudimentary Texinfo manual.
574 * The device defaults to stdin/stdout, unless overridden by the installer.
575 * Option --sparse (-S) should work on more systems.
576 * Option --rsh-command may select an alternative remote shell program.
578 Most changes are internal, and should yield better portability.
580 Version 1.11.2 - Michael Bushnell, 1993-03.
582 * Changes in backup scripts: cleaned up considerably; notices error
583 conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in
584 backup-specs; new file dump-remind is an example of a
587 * Superfluous "Reading dirname" was a bug; fixed.
589 * Incompatibility problems with a bug on Solaris are fixed.
591 * New option --gzip (aliases are --ungzip and -z); calls gzip instead
592 of compress. Also, --use-compress-program lets you specify any
593 compress program. --compress-block is renamed --block-compress and
594 now requires one of the three compression options to be specified.
596 * Several error messages are cleaned up.
598 * Directory owners are now set properly when running as root.
600 * Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option
603 * Behave better with broken rmt servers.
605 * Dump scripts no longer use --atime-preserve; this causes a nasty probem.
607 * Several Makefile cleanups.
609 Version 1.11.1 - Michael Bushnell, 1992-09.
613 Version 1.11 - Michael Bushnell, 1992-09.
614 Version 1.10.16 - 1992-07.
615 Version 1.10.15 - 1992-06.
616 Version 1.10.14 - 1992-05.
617 Version 1.10.13 - 1992-01.
621 * Now uses GNU standard configure, generated by Autoconf.
623 * Long options now use `--'; use of `+' is deprecated and support
624 for it will eventually be removed.
626 * New option --null causes filenames read by -T to be
627 null-terminated, and causes -C to be ignored.
629 * New option --remove-files deletes files (but not directories)
630 after they are added to the archive.
632 * New option --ignore-failed-read prevents read-errors from affecting
635 * New option --checkpoint prints occasional messages as the tape
636 is being read or written.
638 * New option --show-omitted-dirs prints the names of directories
639 omitted from the archive.
641 * Some tape drives which use a non-standard method of indicating
642 end-of-tape now work correctly with multi-tape archives.
644 * --volno-file: Read the volume number used in prompting the user
645 (but not in recording volume ID's on the archive) from a file.
647 * When using --multi-volume, you can now give multiple -f arguments;
648 the various tape drives will get used in sequence and then wrap
649 around to the beginning.
651 * Remote archive names no longer have to be in /dev: any file with a
652 `:' is interpreted as remote. If new option --force-local is given,
653 then even archive files with a `:' are considered local.
655 * New option --atime-preserve restores (if possible) atimes to
656 their original values after dumping the file.
658 * No longer does tar confusingly dump "." when you don't tell it
661 * When extracting directories, tar now correctly restores their
662 modification and access times.
664 * Longnames support is redone differently--long name info directly
665 precedes the long-named file or link in the archive, so you no
666 longer have to wait for the extract to hit the end of the tape for
669 Version 1.10 - Michael Bushnell, 1991-07.
671 * Filename to -G is optional. -C works right. Names +newer and
672 +newer-mtime work right.
674 * -g is now +incremental, -G is now +listed-incremental.
676 * Sparse files now work correctly.
678 * +volume is now called +label.
680 * +exclude now takes a filename argument, and +exclude-from does
681 what +exclude used to do.
683 * Exit status is now correct.
685 * +totals keeps track of total I/O and prints it when tar exits.
687 * When using +label with +extract, the label is now a regexp.
689 * New option +tape-length (-L) does multi-volume handling like BSD
690 dump: you tell tar how big the tape is and it will prompt at that
691 point instead of waiting for a write error.
693 * New backup scripts level-0 and level-1 which might be useful
694 to people. They use a file "backup-specs" for information, and
695 shouldn't need local modification. These are what we use to do
696 all our backups at the FSF.

700 Versions 1.07 back to 1.00 by Jay Fenlason.
702 * See ChangeLog for more details.
