See the end of file for copying conditions.

Please send cpio bug reports to <bug-cpio@gnu.org>.

Downstream backports from newer versions
* New options for copy-out mode:

** --ignore-devno
Store 0 in the device number fields, instead of the actual device
number.

** --renumber-inodes
Renumber inodes when storing them in the archive.

** --device-independent or --reproducible
Create reproducible archives.  This is equivalent to 
--ignore-devno --renumber-inodes.

Version 2.11 - Sergey Poznyakoff, 2010-03-10

* Fix mt build.
* In copy-in mode, if directory attributes do not permit writing to it,
setting them is delayed until the end of run. This allows to correctly
extract files in such directories.
* In copy-in mode, permissions of a directory are restored if it
appears in the file list after files in it (find . -depth). This fixes
debian bug #458079.
* Fix possible memory overflow in the rmt client code (CVE-2010-0624).

Version 2.10 - Sergey Poznyakoff, 2009-06-20

* Ensure record headers are properly packed (fix builds on ARM).
* Fix exit codes to reliably indicate success or failure of the operation.
* Fix large file support.
* Support MinGW builds (thanks to Robert Millan).
* Minor bugfixes.

Version 2.9 - Sergey Poznyakoff, 2007-06-28

* Licensed under the GPLv3.

* Bugfixes:
** Honor umask when creating intermediate directories, not specified
in the archive (debian bug #430053)

Version 2.8 - Sergey Poznyakoff, 2007-06-08

* Option --owner can be used in copy-out mode, allowing to uniformly override
ownership of the files being added to the archive.

* Bugfixes:

** Symlinks were handled incorrectly in copy-out mode.
** Fix handling of large files.
** Fix setting the file permissions in copy-out mode.
** Fix CAN-2005-1111

Version 2.7 - Sergey Poznyakoff, 2006-10-21

* Improved error checking and diagnostics

* Bugfixes
** Fixed CAN-1999-1572
** Allow to use --sparse in both copy-in and copy-pass.
** Fix bug that eventually caused copying out the same hard-linked
file several times to archive.
** Fix several LFS-related issues.
** Fix Debian bug 335580.

Version 2.6 - Sergey Poznyakoff, 2004-12-20

* Added NLS support

* Improved configure script

* Improved invocation consistency checking and help output

* Printing warning about truncation of inode numbers is suppressed by
default. See below.

* New option --warning (-W) controls the level of output warnings:

-Wnone       Disables all warnings
    -Wtruncate   Enable warning about truncation of the inode number
    -Wall        Enables all warnings

To disable a particular warning, prefix its name with 'no-', just
  like in gcc.

* New option --to-stdout extracts files to standard output.

* The output of `cpio --help' is largely improved.
       
* Bugfixes:
** If a file grew n bytes in copy-pass mode, these n bytes got prepended
to the contents of all subsequent files.
** Padding the archive with zero bytes upon truncation of the file being
archived was broken.

Major changes in version 2.5:

* bug fixes from Debian, Red Hat, and SuSE GNU/Linux Distribution patches
* --rsh-command option

Major changes in version 2.4:

* new texinfo documentation
* --sparse option to write sparse files
* --only-verify-crc option to verify a CRC format archive
* --no-absolute-paths option to ignore absolute paths
* --quiet option to supress printing number of blocks copied
* handle disk input errors more gracefully

Major changes in version 2.3:

* in newc and crc format archives, only store 1 copy of multiply linked files
* handle multiply linked devices properly
* handle multiply linked files with cpio -pl even when the source and 
  destination are on different file systems
* support HPUX Context Dependent Files
* read and write HPUX cpio archives
* read System V.4 POSIX tar archives and HPUX POSIX tar archives
* use rmdir, instead of unlink, to delete existing directories

Major changes in version 2.2:

* handle link counts correctly when reading binary cpio archives
* configure checks for some libraries that SVR4 needs

Major changes in version 2.1:

* cpio can access remote non-device files as well as remote devices
* fix bugs in the MS-DOS port
* add --swap equivalent to -b option

Version 2.0 adds the following features:

Support for the SVR4 cpio formats, which can store inodes >65535, and
for traditional and POSIX tar archives.  Also adds these options:

-A --append		append to instead of replacing the archive
-V --dot		print a dot for each file processed
-H --format		select archive format
-C --io-size		select I/O block size in bytes
-M --message		print a message at end of media volumes
--no-preserve-owner	don't change files' owners when extracting
-R --owner		set files' owners when extracting
-E --pattern-file	list of shell filename patterns to process
-s --swap-bytes		handle byte-order differences when extracting files
-S --swap-halfwords	ditto
-b			like -sS
-I			input archive filename
-k			recognize corrupted archives (we alawys do it, though)
-O			output archive filename

Some options of previous versions have been renamed in 2.0:

--binary was replaced by --format=bin
--portability was replaced by --format=odc

Some options have changed meaning in 2.0, for SVR4 compatibility:

-O used to select the binary archive format, now selects the output file
-V used to print the version number, now prints a dot for each file

Version 2.0 also fixes several bugs in the handling of files with
multiple links and of multi-volume archives on floppy disks.
