-   An operating system might already offer message localization for
-many of its programs, while other programs have been installed locally
-with the full capabilities of GNU `gettext'.  Just using `gettext'
-extended syntax for `LANG' would break proper localization of already
-available operating system programs.  In this case, users should set
-both `LANGUAGE' and `LANG' variables in their environment, as programs
-using GNU `gettext' give preference to `LANGUAGE'.  For example, some
-Swedish users would rather read translations in German than English for

-`LANGUAGE' to `sv:de' while leaving `LANG' to `sv'.
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc.  On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'.  You can get the list of
+locales supported by your system for your country by running the command
+`locale -a | grep '^LL''.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.

+Using `gettext' in new packages
+===============================
+
+   If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package.  Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library.  This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+to use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

 ==================

+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set

+`configure' Invocation
+======================
+
   `configure' recognizes the following options to control how it
 operates.

-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
 `--help'

     Print a summary of the options to `configure', and exit.

+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'

+
+`--cache-file=FILE'

+2002-03-05  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (cut invocation): Say that selected input is
+	written in the same order that it is read, and is written
+	exactly once.
+
+2002-03-03  Paul Eggert  <eggert@twinsun.com>
+
+	Make cp -r equivalent to cp -R.  Add a new cp option --copy-contents
+	for people who want to emulate the traditional (and rarely desirable)
+	cp -r behavior.
+
+	* coreutils.texi (cp invocation): Document this.
+	Fix some related minor bugs: --no-dereference is no longer
+	equivalent to -d, and --archive (-a) can override the other
+	symlink options.  Warn that cp -R is not portable on symbolic
+	links unless you also specify -P.
+
+2002-03-02  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): Document that cp -r
+	preserves symlinks.  Emphasize non-portability of cp -r.
+
+2002-02-27  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (Time directives): Add %N for nanoseconds.
+	This documents the recent change to 'ls'.
+
+2002-02-28  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (pr invocation): Reword to avoid using `:'
+	in an @opindex entry -- info doesn't permit it.
+
+2002-02-27  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (Formatting file timestamps): Document new
+	time-formatting method: --time-style=+FORMAT.
+
+2002-02-18  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (seq invocation): In the example, use "tail
+	-n 3", not "tail -3", to conform to POSIX 1003.1-2001.
+
+2002-02-17  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (tsort background): New section.
+	From Ian Lance Taylor.
+	(tsort invocation): Add a more realistic example.
+
+2002-02-15  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi: Document _POSIX2_VERSION.
+	(Standards Conformance): New section.
+
+2002-01-24  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (START-INFO-DIR-ENTRY): Remove a few entries
+	and clean up a few others based on suggestions from Bob Proulx.
+
+2002-02-14  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for POSIX 1003.1-2001, which requires removal for
+	support of obsolete "+" option syntax in sort, tail, and uniq.
+	* coreutils.texi: Document this.  (Also, document a similar
+	change to "touch", for fileutils).
+
+2002-01-12  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (shred invocation): List some journaled filesystems.
+
+2001-11-10  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (Date directives): Document %u.
+
+2001-11-07  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (paste invocation): Give examples.
+	Thanks to Dan Jacobson for suggesting the examples.
+
+2001-11-05  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (sort invocation): Recommend setting LC_ALL=C,
+	not LC_COLLATE=C.  Explain how the latter can cause problems.
+	Based on a message from Paul Eggert.
+	(ls invocation): Recommend setting LC_ALL=C, not LC_COLLATE=C.
+
+2001-10-21  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): Describe --reply=...
+
+2001-10-17  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): `cp --no-dereference' is
+	no longer equivalent to `cp -d'.
+	`cp -d' is equivalent to `--no-dereference --preserve=links'.
+	cp's -P option means --no-dereference, not --parents.
+	Describe new optional argument to --preserve.
+	Describe new option: --no-preserve=ATTRIBUTE_LIST.
+
+2001-09-23  Jim Meyering  <meyering@lucent.com>
+
+	* Makefile.am (check-texinfo): Redirect stderr of `grep -w' to
+	/dev/null, so people with old versions of grep don't see the failure.
+
+2001-09-16  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (mv invocation): Describe new option:
+	--reply={yes,no,query}.  Fix a few typos.
+
+2001-09-15  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (uniq invocation): The input need not
+	be sorted.  Try to clarify -d versus -D versus -u.
+
+2001-09-12  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (tail invocation): Document new option: -F.
+	From Herbert Xu.
+
+2001-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi (join invocation): Describe the GNU
+	extension to join, which does not require sorted input when
+	the input contains no unpairable lines.
+
+2001-09-03  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi:
+	New 'uname' options -i or --hardware-platform,
+	and -o or --operating-system.
+	'uname -a' now outputs -i and -o information at the end.
+	New uname option --kernel-version is an alias for -v.
+	Uname option --release has been renamed to --kernel-release,
+	and --sysname has been renamed to --kernel-name;
+	the old options will work for a while, but are no longer documented.
+
+2001-08-24  Herbert Xu  <herbert@gondor.apana.org.au>
+
+	* coreutils.texi (cut invocation): Document how cut treats lines
+	with no separators.
+
+2001-06-19  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi: expr now uses LC_COLLATE for string comparison,
+	as per POSIX.
+
+2001-08-25  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi: Use @option, rather than @samp everywhere.
+
+2001-06-21  Paul Eggert  <eggert@twinsun.com>
+
+	* coreutils.texi: 'expr' now requires '+' rather than 'quote'
+	to quote tokens.
+
+2001-07-14  Jim Meyering  <meyering@lucent.com>
+
+	* coreutils.texi (cp invocation): Reflect 2001-07-08 change to
+	cp (via copy.c).
+
+2001-06-16  Jim Meyering  <meyering@lucent.com>
+
+	* Makefile.am (info_TEXINFOS): Reflect renaming: s/omni-/core/.
+	* coreutils.texi: Likewise.
+
+	* coreutils.texi: New, renamed from omni-utils.texi.
+	* omni-utils.texi: Removed, renamed to coreutils.texi.
+
+	* omni-utils.texi (ls invocation): Mention the effect of locale.
+	Reported by Keith Thompson.
+
+2001-05-24  Jim Meyering  <meyering@lucent.com>
+
+	* texinfo.tex: Update from master source.
+
+	* omni-utils.texi (ls invocation): Document more clearly what ls
+	does when given no arguments.
+
+2001-05-21  Jim Meyering  <meyering@lucent.com>
+
+	* textutils.texi: Remove file.
+
+	* Makefile.am ($(DVIS), $(INFO_DEPS)): Depend on $(EXTRA_DIST).
+	(DISABLED_constants.texi): New rule -- disabled for now.
+
+	This directory is now shared by fileutils, textutils, and sh-utils.

+* How to use this License for your documents::
+@end menu
+@end ifnottex
+@display
+Copyright (C) 2000  Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Everyone is permitted to copy and distribute verbatim copies

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+written document ``free'' in the sense of freedom: to assure everyone
+the effective freedom to copy and redistribute it, with or without
+modifying it, either commercially or noncommercially.  Secondarily,
+this License preserves for the author and publisher a way to get
+credit for their work, while not being considered responsible for
+modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+@iftex
+@sp1
+@end iftex
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work that contains a
+notice placed by the copyright holder saying it can be distributed
+under the terms of this License.  The ``Document'', below, refers to any
+such manual or work.  Any member of the public is a licensee, and is
+addressed as ``you''.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject.  (For example, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, whose contents can be viewed and edited directly and
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent.  A copy that is
+not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML designed for human modification.  Opaque formats include
+PostScript, PDF, proprietary formats that can be read and edited only
+by proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML produced by some word processors for output
+purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+@iftex
+@sp1

+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+@iftex
+@sp1
+@end iftex
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies of the Document numbering more than 100,
+and the Document's license notice requires Cover Texts, you must enclose
+the copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols.  If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+@iftex
+@sp1
+@end iftex
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+   from that of the Document, and from those of previous versions
+   (which should, if there were any, be listed in the History section
+   of the Document).  You may use the same title as a previous version
+   if the original publisher of that version gives permission.@*
+B. List on the Title Page, as authors, one or more persons or entities
+   responsible for authorship of the modifications in the Modified
+   Version, together with at least five of the principal authors of the
+   Document (all of its principal authors, if it has less than five).@*
+C. State on the Title page the name of the publisher of the
+   Modified Version, as the publisher.@*
+D. Preserve all the copyright notices of the Document.@*
+E. Add an appropriate copyright notice for your modifications
+   adjacent to the other copyright notices.@*
+F. Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the Modified Version under the
+   terms of this License, in the form shown in the Addendum below.@*
+G. Preserve in that license notice the full lists of Invariant Sections
+   and required Cover Texts given in the Document's license notice.@*
+H. Include an unaltered copy of this License.@*
+I. Preserve the section entitled ``History'', and its title, and add to
+   it an item stating at least the title, year, new authors, and
+   publisher of the Modified Version as given on the Title Page.  If
+   there is no section entitled ``History'' in the Document, create one
+   stating the title, year, authors, and publisher of the Document as
+   given on its Title Page, then add an item describing the Modified
+   Version as stated in the previous sentence.@*
+J. Preserve the network location, if any, given in the Document for
+   public access to a Transparent copy of the Document, and likewise
+   the network locations given in the Document for previous versions
+   it was based on.  These may be placed in the ``History'' section.
+   You may omit a network location for a work that was published at
+   least four years before the Document itself, or if the original
+   publisher of the version it refers to gives permission.@*
+K. In any section entitled ``Acknowledgements'' or ``Dedications'',
+   preserve the section's title, and preserve in the section all the
+   substance and tone of each of the contributor acknowledgements
+   and/or dedications given therein.@*
+L. Preserve all the Invariant Sections of the Document,
+   unaltered in their text and in their titles.  Section numbers
+   or the equivalent are not considered part of the section titles.@*
+M. Delete any section entitled ``Endorsements''.  Such a section
+   may not be included in the Modified Version.@*
+N. Do not retitle any existing section as ``Endorsements''
+   or to conflict in title with any Invariant Section.@*
+@iftex
+@sp1
+@end iftex
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a

+   setvbuf to inhibit buffering.

+   that writes to stdout -- just let the internal stream state record
+   the failure.  That's what the ferror test is checking below.
+
+   It's important to detect such failures and exit nonzero because many
