Notes on the Free Translation Project
*************************************
Free software is going international! The Free Translation Project is
a way to get maintainers of free software, translators, and users all
together, so that will gradually become able to speak many languages.
A few packages already provide translations for their messages.
If you found this `ABOUT-NLS' file inside a distribution, you may
assume that the distributed package does use GNU `gettext' internally,
itself available at your nearest GNU archive site. But you do _not_
need to install GNU `gettext' prior to configuring, installing or using
this package with messages translated.
Installers will find here some useful hints. These notes also
explain how users should proceed for getting the programs to use the
available translations. They tell how people wanting to contribute and
work at translations should contact the appropriate team.
When reporting bugs in the `intl/' directory or bugs which may be
related to internationalization, you should tell about the version of
`gettext' which is used. The information can be found in the
`intl/VERSION' file, in internationalized packages.
Quick configuration advice
==========================
If you want to exploit the full power of internationalization, you
should configure it using
./configure --with-included-gettext
to force usage of internationalizing routines provided within this
package, despite the existence of internationalizing capabilities in the
operating system where this package is being installed. So far, only
the `gettext' implementation in the GNU C library version 2 provides as
many features (such as locale alias, message inheritance, automatic
charset conversion or plural form handling) as the implementation here.
It is also not possible to offer this additional functionality on top
of a `catgets' implementation. Future versions of GNU `gettext' will
very likely convey even more functionality. So it might be a good idea
to change to GNU `gettext' as soon as possible.
So you need _not_ provide this option if you are using GNU libc 2 or
you have installed a recent copy of the GNU gettext package with the
included `libintl'.
INSTALL Matters
===============
Some packages are "localizable" when properly installed; the programs
they contain can be made to speak your own native language. Most such
packages use GNU `gettext'. Other packages have their own ways to
internationalization, predating GNU `gettext'.
By default, this package will be installed to allow translation of
messages. It will automatically detect whether the system already
provides the GNU `gettext' functions. If not, the GNU `gettext' own
library will be used. This library is wholly contained within this
package, usually in the `intl/' subdirectory, so prior installation of
the GNU `gettext' package is _not_ required. Installers may use
special options at configuration time for changing the default
behaviour. The commands:
./configure --with-included-gettext
./configure --disable-nls
will respectively bypass any pre-existing `gettext' to use the
internationalizing routines provided within this package, or else,
_totally_ disable translation of messages.
When you already have GNU `gettext' installed on your system and run
configure without an option for your new package, `configure' will
probably detect the previously built and installed `libintl.a' file and
will decide to use this. This might be not what is desirable. You
should use the more recent version of the GNU `gettext' library. I.e.
if the file `intl/VERSION' shows that the library which comes with this
package is more recent, you should use
./configure --with-included-gettext
to prevent auto-detection.
The configuration process will not test for the `catgets' function
and therefore it will not be used. The reason is that even an
emulation of `gettext' on top of `catgets' could not provide all the
extensions of the GNU `gettext' library.
Internationalized packages have usually many `po/LL.po' files, where
LL gives an ISO 639 two-letter code identifying the language. Unless
translations have been forbidden at `configure' time by using the
`--disable-nls' switch, all available translations are installed
together with the package. However, the environment variable `LINGUAS'
may be set, prior to configuration, to limit the installed set.
`LINGUAS' should then contain a space separated list of two-letter
codes, stating which languages are allowed.
Using This Package
==================
As a user, if your language has been installed for this package, you
only have to set the `LANG' environment variable to the appropriate
`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
and `CC' is an ISO 3166 two-letter country code. For example, let's
suppose that you speak German and live in Germany. At the shell
prompt, merely execute `setenv LANG de_DE' (in `csh'),
`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
This can be done from your `.login' or `.profile' file, once and for
all.
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'.
Special advice for Norwegian users: The language code for Norwegian
bokma*l changed from `no' to `nb' recently (in 2003). During the
transition period, while some message catalogs for this language are
installed under `nb' and some older ones under `no', it's recommended
for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
older translations are used.
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.
Translating Teams
=================
For the Free Translation Project to be a success, we need interested
people who like their own language and write it well, and who are also
able to synergize with other translators speaking the same language.
Each translation team has its own mailing list. The up-to-date list of
teams can be found at the Free Translation Project's homepage,
`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
area.
If you'd like to volunteer to _work_ at translating messages, you
should become a member of the translating team for your own language.
The subscribing address is _not_ the same as the list itself, it has
`-request' appended. For example, speakers of Swedish can send a
message to `sv-request@li.org', having this message body:
subscribe
Keep in mind that team members are expected to participate
_actively_ in translations, or at solving translational difficulties,
rather than merely lurking around. If your team does not exist yet and
you want to start one, or if you are unsure about what to do or how to
get started, please write to `translation@iro.umontreal.ca' to reach the
coordinator for all translator teams.
The English team is special. It works at improving and uniformizing
the terminology in use. Proven linguistic skill are praised more than
programming skill, here.
Available Packages
==================
Languages are not equally supported in all packages. The following
matrix shows the current state of internationalization, as of January
2004. The matrix shows, in regard of each package, for which languages
PO files have been submitted to translation coordination, with a
translation percentage of at least 50%.

Some counters in the preceding matrix are higher than the number of
visible blocks let us expect. This is because a few extra PO files are
used for implementing regional variants of languages, or language
dialects.
For a PO file in the matrix above to be effective, the package to

distributed as such by its maintainer. There might be an observable
lag between the mere existence a PO file and its wide availability in a
distribution.

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
the 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.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved.
For generic installation instructions on compiling and installing this
Automake-based distribution, please read the file `INSTALL.generic'.
Installation notes specific to Texinfo:
* texinfo.tex and the other *.tex files are not installed by `make
install'. This is because there is no reliable way to know where to
install them. Instead, you have to run an additional make command
after the normal make install:
make TEXMF=/your/texmf install-tex
texinfo.tex is installed in ${TEXMF}/tex/texinfo/texinfo.tex, etc.
* On the other hand, if you're maintaining a TeX distribution, you don't
want your users to see the installation warnings, because you already
have the files installed. (And you're keeping them up to date, right?)
In this case, run configure --disable-install-warnings, or set
enable_install_warnings=no in the environment.
* On MacOSX, if configure fails with the error:
ac_cv_build='config.sub: invalid option -apple-darwin7.2.0
this is probably because your uname -p is returning "unknown". Use
/usr/bin/uname instead.
* For instructions on compiling this distribution with DJGPP tools
for MS-DOS and MS-Windows, see the file djgpp/README.
* The Info tree uses a file `dir' as its root node; the `dir-example'
file in this distribution is included as a possible starting point.
Use it, modify it, or ignore it just as you like.
* You can create a file texinfo.cnf to be read by TeX when
processing Texinfo manuals. For example, you might like to use
@afourpaper by default. See the `Preparing for TeX' node in
texinfo.txi for more details. You don't have to create the file if
you have nothing to put in it.
* If your info files are not in $prefix/info, you may wish to add a line
#define DEFAULT_INFOPATH "/mydir1:/mydir2:..."
to config.h after running configure.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PREFIX', the package will
use PREFIX as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the `--target=TYPE' option to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
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
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script).
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

============================
"Texinfo" is a documentation system that uses a single source file to
produce both on-line information and printed output. Using Texinfo,
you can create a printed document with the normal features of a book,
including chapters, sections, cross references, and indices. From the
same Texinfo source file, you can create a menu-driven, on-line Info
file with nodes, menus, cross references, and indices.
The name of the Texinfo source documentation file is `texinfo.txi'.
You can produce both on-line information and printed output from this
source file. The documentation describes Texinfo in detail, including
how to write Texinfo files, how to format them for both hard copy and
Info, and how to install Info files.
To get started, you need to create either a printed manual or an
on-line Info file from the `texinfo.txi' file. You do not need to
create both, although you will probably want both eventually.
To learn how to use Info, read the info documentation. You can do this in
one of two ways: using the standalone `info' program, or using Info mode in
GNU Emacs.
* If you want to use the `info' program, run
info -f info-stnd
* If you want to use Emacs, start up emacs and type `C-h i' [M-x info].
Follow the instructions to learn how to use Info.
After learning how to use Info, you can read the Texinfo documentation.
Using the standalone `info', type the following at the shell prompt:
info -f texinfo
To use read this manual in Emacs, you first need to edit the Info-directory
menu (the file `dir' in the system info directory) to contain the
appropriate node. To learn how to do this, see node: Add in the Info
documentation.
The Texinfo documentation describes Texinfo in detail; among other things,
it tells how to install Info files in the usual manner. (See node: Install
an Info File.)
The `info-stnd.info' file describes the standalone Info reader in detail. To
read this file, type
$ info -f info-stnd
To create a printed manual
==========================
You need:
* The `tex' program, which typesets the manual using TeX.
* The `texinfo.tex' definition file that tells TeX how to typeset
a Texinfo file.
* The `texindex' program, which sorts the unsorted index files
created by TeX.
* A printing program such as `lp' or `lpr',
* A printer.
This Texinfo distribution package contains `texinfo.tex', the C source
for `texindex', and the handy shell script `texi2dvi'. The `tex'
program is not part of this distribution, but is available separately.
(See `How to Obtain TeX' in the Texinfo documentation.)
* Install `tex'. (`texindex' is installed automagically by
`make install' in this distribution.)
* Move the `texinfo.tex' file to an appropriate directory; the current
directory will do. (`/usr/local/lib/tex/inputs' might be a good place.
See ``Preparing to Use TeX'' in the Texinfo manual, for more
information.)
After following those instructions, type the following to make the .dvi
files:
$ (cd doc; make dvi)
You can then print the resulting .dvi files with the `lpr' or `lp'
commands, or maybe `dvips'.
For example, the command to print the texinfo.dvi file might be:
$ lpr -d texinfo.dvi
The name of the printing command depends on the system; `lpr -d' is
common, and is illustrated here. You may use a different name for the
printing command.
Please report bugs to bug-texinfo@gnu.org.
Happy formatting.

*** IMPORTANT NEWS FOR ALL AUTHORS OF TEXINFO MANUALS ***
As of version 4.2, Texinfo has a new command @copying to define the
copyright and copying permissions for a manual. It's important to
switch to using it as soon as possible (as in your next release),
because the historical method of doing copyright permissions using
@ifinfo failed to output copyright information in the HTML (or XML)
formats. The manual has detailed explanations and examples. For
convenience, here's a url to one of the relevant sections:
http://www.gnu.org/software/texinfo/manual/texinfo/html_node/Document-Permissions.html
-------------------------------------------------------------------------------
4.8 (31 December 2004)
* Language:
. new command @euro for the Euro currency symbol, and
@documentencoding has some support for ISO-8859-15.
. new command @abbr for general abbreviations.
. new command @slanted to typeset text in a slanted font,
and @sansserif to typeset in a sans serif font.
* makeinfo:
. An empty first argument to cross-reference commands, such as @xref,
causes an error. This change was made in 4.1, but not mentioned in NEWS.
. HTML output:
- <a name="..."> constructs are added for the old-style
conversion of node names to HTML names, so that external references
to them can continue to work.
- "g_t" prefixed to targets for node names beginning with a
nonletter, for XHTML compatibility.
. Docbook output: recognize more image formats.
* texi2dvi:
. new option --recode, to call recode for input character translation.
* Distribution:
. new convenience script texi2pdf, equivalent to texi2dvi --pdf (from tetex).
. some cross-compiling support in configure && make.
. new configure option --disable-install-warnings, for TeX.
distributions which do have the files installed.
. automake 1.9.4.
4.7 (9 April 2004)
* Language:
. new commands @float, @caption, @shortcaption, @listoffloats for
initial implementation of floating material (figures, tables, etc).
Ironically, they do not yet actually float anywhere.
. new commands @docbook, @ifdocbook, @ifnotdocbook for conditional Docbook.
. new commands @ordf{} and @ordm{} for Spanish feminine/masculine ordinals.
. new commands @deftypecv[x] for class variables in typed OO languages.
. new command @registeredsymbol for the r-in-a-circle symbol.
. new command @headitem to make a heading row in @multitable.
. new command @LaTeX{} for the LaTeX logo.
. new command @comma{} to avoid comma-parsing problems.
. @url is now a synonym for @uref; new command @indicateurl has the
old meaning of just displaying a url as text.
. @quotation now accepts an optional argument for labelling the text
as a `Note', `Tip', etc.
. @defun (et al.) heading lines can now be continued with a lone @.
. @acronym accepts an optional argument for the meaning of the acronym.
* makeinfo:
. New environment variable TEXINFO_OUTPUT_FORMAT determines the output
format at runtime, if no options are specified.
. New option --plaintext, equivalent to --no-headers with Info output.
. All outputs:
- sections are numbered by default.
. Info output:
- punctuation is inserted after @pxref and @ref, if needed to make
cross-references valid.
- line numbers included in index menus, so Info readers can go to
the exact line of an entry, not just a node. Also in plaintext output.
- ^@^H[index^@^H] cookie included in index menus, so Info readers
can handle the ] etc. commands better.
. HTML output:
- new algorithm for cross-references to other manuals, for maximum
portability and stability.
- include node name in <title> with split output.
- @multicolumn fractions become percentages.
- entities used for bullets, quotes, dashes, and others.
- index entries are links to the exact locations.
- <h4> and <h5> used for @sub and @subsubsections again.
- accented dotless i supported.
. XML output: many new tags and structure to preserve more source features.
. Docbook output:
- upgraded DTD to Docbook XML 4.2, no longer using Docbook SGML.
- improved translation in general, for instance:
- line annotations and marked quotations.
* texi2dvi:
. if available, use etex (pdfetex if --pdf) by default.
. if the input file includes thumbpdf.sty (for LaTeX), then run thumbpdf.
. more output if --debug.
* texinfo.tex:
. @defun names are now printed in typewriter (instead of bold), and
within the arguments, @var text is printed in slanted typewriter.
. @tex code is executed inside a TeX group, so that any changes must
be prefixed with \global (or the equivalent) to be effective. (This
change was actually made years ago, but never made it into the NEWS.)
* info:
. new option --where (aka --location, -w) to report where an Info file
would be found, instead of reading it.
. by default, output ANSI terminal escape sequences as-is; new option
--no-raw-escapes overrides this.
. use the newly-generated index line numbers.
* Distribution:
. new script gendocs.sh (not installed), for use by GNU maintainers in
getting their manuals on the GNU web site. Documented in
maintain.texi (http://www.gnu.org/prep/maintain/).
. Most code uses ANSI C prototypes, to some extent.
. New translation: nb.
. automake 1.8.3, autoconf 2.59, gettext 0.14.1.
4.6 (10 June 2003)
* Language:
. new command @/ specifies an allowable breakpoint within a line.
. new command @dofirstparagraphindent to control whether the first
paragraph following a section heading is indented. Default is to
omit this indentation, unlike the output up to now.
. new command @indent for explicitly indenting a paragraph.
. makeinfo writes a new construct for @image in Info output, so that
graphical Info browsers (such as Emacs Info under X) can display an
actual image. (Standalone Info ignores this, since it runs in a tty.)
* makeinfo:
. Common:
- search for image files in the include file search path.
- warns if @value is used on an undefined variable.
. Info output:
- default --split-size now 300,000 bytes, up from 50,000.
- with --enable-encoding and a given @documentencoding,
output a Local Variables section specifying that encoding, for use
with Emacs.
. HTML output:
- uses <h3> at the smallest.
- a few css <style> definitions are included to better
implement @format, @display, @small..., etc.
- new option --css-include=FILE includes FILE in the <style>.
- @cartouche now outputs a <table> with a border.
* texinfo.tex:
. new Polish translation txi-pl.tex.
* texi2dvi:
. --command=CMD replaces --texinfo=CMD; it inserts CMD at the first
line of LaTeX files now, or after the @setfilename for Texinfo files.
* info:
. RET now goes to the nearest xref (rather like Emacs Info),
instead of the next xref starting on the current line.
* Distribution:
. new Romanian (ro) translation.
. variables now declared const where appropriate.
. gettext 0.12.1, automake 1.7.5.
4.5 (4 February 2003)
* info:
. a bug in 4.4 prevented compressed info files from being found.
* Distribution:
. detect sys/ptem.h on Solaris.
4.4 (31 January 2003)
* Language:
. The ' (ASCII apostrophe/right quote) character is finally allowed in
node and anchor names. Thus, after installing this texinfo.tex,
existing .aux files will cause errors! Remove them and rerun TeX to
generate good ones.
. @value constructs are now expanded in the filename arguments to
@include and @verbatiminclude.
* makeinfo:
. @macro names may no longer include ^ or _, for the sake of math mode.
. bug fix: @copying text is now reflected in tag table positions;
before, nodes may not have been found with a long-enough @copying.
. bug fix: html @verb arg is quoted properly, and does not imply
a paragraph break.
* texinfo.tex:
. @smallexample and the like now output in a smaller font (9pt) in all
paper formats, not just @smallbook and @afourpaper.
. new translation txi-tr.tex.
. bug fix: <>| and other characters do not disappear when they are
first on a line in @verbatim.
* install-info:
. bug fix: don't translate the `* Menu' info keyword.
* info:
. CTRL-H is treated like DEL in incremental search.
. arrow keys once again work in isearch contexts under Solaris.
* infokey:
. use .info key bindings before defaults.
. allow prefix keys to be disabled.
* Distribution:
. update to GNU FDL 1.2 (http://www.gnu.org/licenses/fdl.html).
. getopt and other common library files updated from gnulib
(http://savannah.gnu.org/projects/gnulib/).
. autoconf 2.57, automake 1.7.2.
4.3 (14 November 2002)
* Language:
. new command @tie{} to do a real tie (unbreakable interword space).
* makeinfo:
. html output for @defun and friends now has font changes.
. html output has some class attributes.
. xml and docbook output improved in many details.
* texinfo.tex:
. new Italian translations, txi-it.tex.
. pdf bookmarks for unnumbered sections work.
. type name for @defun and friends no longer extends into margin.
* info:
. automatic-footnotes now off by default, for emacs compatibility.
. crash when MALLOC_CHECK_=2 fixed.
* install-info:
. new option --infodir synonym for --info-dir, for compatibility with
the Debian install-info.
. support for bzip2-compressed files.
* texindex:
. omit initial if the entire index is under one character.
* Distribution:
. development sources now available under CVS, see
http://savannah.gnu.org/projects/texinfo/
. Turkish message translation.
. gettext 0.11.5, autoconf 2.54, automake 1.7.1.
4.2 (1 April 2002)
* Language:
. new command @copying to define copying permissions. See above.
. new conditionals @ifplaintext, @ifnotplaintext for the plain text
(--no-headers) output format.
. new command @\ to produce literal \ inside @math, since \ by itself
no longer works.
* makeinfo:
. emit accesskey attributes for keyboard shortcuts to menu items.
. @{even,every,odd}{footing,header} are ignored by makeinfo now, so
they no longer need to be enclosed in @iftex.
* texinfo.tex:
. bug fix for pdf-format table of contents.
* info:
. bug fixes for -R (--raw-escapes).
. --help shows short option names.
* Distribution:
. the doc.c, funs.h, and key.c files in info/ are no longer generated
at make time, to appease Automake's make distcheck.
. gettext 0.11.1, autoconf 2.53, automake 1.6 (with install-info kludge).
4.1 (4 March 2002)
* Language:
. new commands @verbatim and @verb for printing verbatim inserts.
. new command @verbatiminclude for verbatim include of files.
. new environment @documentdescription for defining the HTML description.
. new command @afivepaper for the A5 paper size.
* makeinfo:
. supports xml and docbook output.
. supports HTML splitting by node, which is now the default.
. new option --split-size to control maximum size of split info files.
. new option --enable-encoding to enable
* info:
. user-specified key bindings supported.
. ANSI escape sequences (as produced by groff) removed from man output
by default; use --raw-escapes to let them through if your terminal
supports them.
. RET terminates incremental search normally.
* texinfo.tex:
. @math implies @tex, so all the usual plain TeX math is supported.
. smaller fonts for @smallexample, in all page sizes.
. improvements in the PDF support.
* texi2dvi:
. new option -o to explicitly specify output filename.
* Distribution:
. switch to GNU Free Documentation License (http://www.gnu.org/copyleft/).
. update to GNU gettext 0.11, autoconf 2.52, and automake 1.5.
. Danish, Swedish, and Hebrew message translations.
4.0 (28 September 1999)
* Language:
. New command @anchor for cross references to arbitrary points.
. New commands @documentlanguage sets the main document language,
and @documentencoding sets the document input encoding (although not
much is done yet with either).
. New command @pagesizes allows limited control of text area for typesetting.
. New command @acronym for abbreviations in all caps, such as `NASA'.
. New command @alias for simple command aliases.
. New command @definfoenclose for better control of info output.
. New commands @deftypeivar for typed instance variables of a class
and @deftypeop for typed operations of a class.
. New command @novalidate suppresses cross-reference checking and (in
TeX) auxiliary file creation.
. New commands @setcontentsaftertitlepage and
@setshortcontentsaftertitlepage to force printing the table of
contents after @end titlepage. Also, @contents and @shortcontents
themselves can now appear at the beginning of the document as
well as the end.
. New markup commands: @env (for environment variables), @command (for
command names), @option (for command-line options).
. New commands @smallformat and @smalldisplay, a la @smallexample.
. New command @exampleindent to set indentation of example-like
environments a la @paragraphindent.
. @uref takes an optional third argument of text to show instead of
(rather than in addition to) the url for info and dvi output.
. @footnote works in an @item for a @table.
* texinfo.tex:
. latest version always at ftp://ftp.gnu.org/gnu/texinfo/texinfo.tex
(and mirrors).
. implements @macro.
. implements @paragraphindent (except asis).
. @emph and @i use true italic type (cmti) instead of slanted (cmsl).
. implements pdf output when run with pdftex.
. better support for internationalization via txi-??.tex files.
. footnotes now set in a smaller point size.
* makeinfo:
. supports HTML output with the --html option.
. implication of --html: @top nodes should be wrapped in @ifnottex
rather than @ifinfo. @ifinfo conditionals are not expanded with --html.
. new option --number-sections to output chapter/section numbers.
. dashes and quotes are not treated specially in node names.
. new option --commands-in-node-names to allow @-commands in node names.
(Not implemented in TeX, and most likely never will be.)
. @emph output uses _underscores_.
. @image looks for .png files before .jpg.
. only output `Making ... file' line when verbose.
. allow -v as synonym for --verbose.
. new command line options to specify which conditionals to process
(but --iftex is not fully implemented).
. warns if @var contains any of ,[]().
. @quote-arg implicitly done for all one-argument macros, so commas in
the argument text are allowed.
. \\ required in macro body to get single \, no other `escapes' defined.
* info:
. ISO Latin 1 characters are displayed and input as-is by default.
. new option --vi-keys to enable vi-like and less-like key bindings.
. new command S does case-sensitive searching.
. new commands C-x n and C-x N repeat last search, respectively, in the
same and in reverse direction, without prompting for the string. These
commands are bound to n and N under --vi-keys, like in Less.
. new command G menu1 menu2 ... searches for menu items from (dir),
as allowed on the command line.
. new command O (capital o, not zero) goes directly to the node that
describes command-line options.
. new command-line option --show-options causes the node which
describes command-line options to be the first node displayed.
. M-prior and M-DEL do new command info-scroll-other-window-backward.
. / searches like s does.
. If the search string includes upper-case letters, in both incremental
and non-incremental search, the search is case-sensitive.
. S searches case-sensitively even if the search string is all
lower-case.
. - makes the argument negative (so e.g. `- /' searches backward).
. l restores point in the window returned to.
. SPC/DEL do not move outside the current document.
. foo.info is found before foo.
. `info foo --index-search=bar' now searches for bar in foo's index.
. support for files compressed with bzip2.
* install-info:
. handles gzipped dir files.
. sort entries into alphabetical order.
. install direntries only in preceding dircategory, not in all.
. --delete does not require the info file to exist.
. --delete can handle XEmacs-style dir entries.
* texi2dvi:
. bug fixed: now uses only the @iftex and @tex parts of the source.
. process LaTeX source as well as Texinfo source.
. output PDF (using pdftex) with new option --pdf.
. handles --OPTION=ARG style of command line arguments.
. new option --batch for progress reports but no interaction.
. new option --clean to remove all auxiliary files.
. new option --quiet for silence (unless there are errors).
. new option -I for specifying directories for @include to search.
. handles LaTeX files (running BibTeX etc.).
* Fixes to util/gen-dir-node and util/fix-info-dir (formerly util/update-info).
* Distribution:
. Man pages included.
. Czech and Norwegian message translations.
. Various translations for texinfo.tex fixed words included.
. DJGPP support.
3.12 (3 March 1998)
* Elisp files removed, since they are only usefully distributed with Emacs.
* Restore inclusion of compile-time $(infodir) to INFOPATH.
* install-info creates a proper dir file.
* Various portability fixes.
3.11 (31 July 1997)
* New commands:
- @uref to make a reference to a url; @url now only indicates such.
- @image to include graphics (epsf for TeX).
- @deftypemethod and @deftypemethodx to document methods in strongly
typed object-oriented languages, such as C++.
- @html for raw HTML.
- @ifnothtml @ifnotinfo @ifnottex for more precise conditionals.
- @kbdinputstyle to control when @kbd uses the slanted typewriter font.
- @email takes second optional argument.
* texinfo.tex reads texinfo.cnf (if present) for site-wide TeX
configuration; for example, A4 paper sizes.
* info:
- arrow keys supported.
- trailing : in INFOPATH appends default path.
- new option --index-search for online help support.
* makeinfo:
- output files removed if errors unless (new option) --force.
- new option -P to prepend to search path.
- macro expansion file can be standard output.
* install-info creates a new dir file if necessary.
* update-info script to create a dir file from all info files.
* Elisp: texnfo-tex.el and detexinfo.el removed from the distribution;
- texnfo-tex features are now part of standard TeX & Texinfo packages;
- makeinfo --no-headers does a better job than detexinfo.el.
* Documentation:
- Updates, revisions, corrections in the manual.
- makeinfo.texi removed, as it was a copy of what was in texinfo.texi.
* gettext support in sources, French and German translations included.
* info man page removed; use the Texinfo manual.
* Automake used, other portability fixes.
3.10 (nonexistent)
3.9 (4 October 1996)
* makeinfo:
- Give a suppressible (with --no-validate) error for references
outside of any node.
- Keep track of multitable output correctly for split files; this
caused nodes after the first multitable to be ``undefined''.
* install-info:
- Rename --infodir option to --info-dir.
- More robust error checking to avoid various crashes.
* configure: Include replacements for memcpy and memmove functions in
the distribution, in case they are missing.
3.8 (30 September 1996)
* Define and/or document new and/or previously existing commands:
Accents: @" @' @, @" @= @^ @` @~ @H @d @dotaccent @dotless @ringaccent
@tieaccent @u @ubaraccent @v
Special characters: @AA @AE @L @O @OE @aa @ae @exclamdown @l @o @oe
@pounds @questiondown @ss
Special punctuation: @! @? @enddots
dir file maintenance: @dircategory @direntry; also new program, install-info
HTML support: @email @url @ifhtml...@end ifhtml
Macros: @macro @unmacro
Tables: @multitable @tab
Hyphenation: @- @hyphenation
Spacing: @ @<TAB> @<NEWLINE>
Sectioning:
@headings singleafter/doubleafter (change heading style after current page)
@centerchap
@setchapterstyle
Other:
@shorttitlepage (simple title pages)
@detailmenu...@end detailmenu (help makeinfo parse master menus)
* Makeinfo prefers an input file named `foo.texinfo' or `foo.texi' or
`foo.txinfo' to just `foo' (the latter most likely being an executable).

3.1 (23 May 1993)
Just bug fixes, see ChangeLog for full details.
3.0: first release of Texinfo version 2, with many new commands.
Here is the separate NEWS for old releases of Info:
Version 2.11, Sat Apr 1 09:15:21 1995
Changes since 2.7 beta:
Although the basic code remains the same, there are numerous nits
fixed, including some display bugs, and a memory leak. Some changes
that have taken place with larger impact include the way in which the
(dir) node is built; I have added in support for "localdir"
directories among other things. Info files may be stored in
compressed formats, and in their own subdirectories; menu items which
do not explicitly name the node to which they are attached have the
menu item name looked up as an Info file if it is not found within the
current document. This means that the menu item:
* Info:: The Info documentation reader.
in (dir) refers to the info node "(info)Top".
Please see the ChangeLog and documentation for details on other
changes.
Version 2.7 beta, Wed Dec 30 02:02:38 1992
Version 2.6 beta, Tue Dec 22 03:58:07 1992
Version 2.5 beta, Tue Dec 8 14:50:35 1992
Version 2.4 beta, Sat Nov 28 14:34:02 1992
Version 2.3 beta, Fri Nov 27 01:04:13 1992
Version 2.2 beta, Tue Nov 24 09:36:08 1992
Version 2.1 beta, Tue Nov 17 23:29:36 1992
Changes since 2.5 beta:
Note that versions 2.6 and 2.7 Beta were only released to a select group.
* "info-" removed from the front of M-x commands.
* Automatic footnote display. When you enter a node which contains
footnotes, and the variable "automatic-footnotes" is "On", Info pops
up a window containing the footnotes. Likewise, when you leave that
node, the window containing the footnotes goes away.
* Cleaner built in documentation, and documentation functions.
Use:
o `M-x describe-variable' to read a variable's documenation
o `M-x describe-key' to find out what a particular keystroke does.
o `M-x describe-function' to read a function's documentation.
o `M-x where-is' to find out what keys invoke a particular function.
* Info can "tile" the displayed windows (via "M-x tile-windows"). If
the variable "automatic-tiling" is "On", then splitting a window or
deleting a window causes the remaining windows to be retiled.
* You can save every keystroke you type in a "dribble file" by using the
`--dribble FILENAME' option. You can initially read keystrokes from an
alternate input stream with `--restore FILENAME', or by redirecting
input on the command line `info < old-dribble'.
* New behaviour of menu items. If the label is the same as the
target node name, and the node couldn't be found in the current file,
treat the label as a file name. For example, a menu entry in "DIR"
might contain:
* Emacs:: Cool text-editor.
Info would not find the node "(dir)Emacs", so just plain "(emacs)"
would be tried.
* New variable "ISO-Latin" allows you to use European machines with
8-bit character sets.
* Cleanups in echo area reading, and redisplay. Cleanups in handling the
window which shows possible completions.
* Info can now read files that have been compressed. An array in filesys.c
maps extensions to programs that can decompress stdin, and write the results
to stdout. Currently, ".Z"/uncompress, ".z"/gunzip, and ".Y"/unyabba are
supported. The modeline for a compressed file shows "zz" in it.
* There is a new variable "gc-compressed-files" which, if non-zero, says
it is okay to reclaim the file buffer space allocated to a file which
was compressed, if, and only if, that file's contents do not appear in
any history node.
* New file `nodemenu.c' implements a few functions for manipulating
previously visited nodes. `C-x C-b' (list-visited-nodes) produces a
menu of the nodes that could be reached by info-history-node in some
window. `C-x b' (select-visited-node) is similar, but reads one of
the node names with completion.
* Keystroke `M-r' (move_to_screen_line) allows the user to place the cursor at
the start of a specific screen line. Without a numeric argument, place the
cursor on the center line; with an arg, place the cursor on that line.
* Interruptible display implemented. Basic display speedups and hacks.
* The message "*** Tags Out of Date ***" now means what it says.
* Index searching with `,' (info-index-next) has been improved.
* When scrolling with C-v, C-M-v, or M-v, only "Page Only" scrolling
will happen.
* Continous scrolling (along with `]' (info-global-next) and `['
(info-global-prev) works better. `]' and `[' accept numeric
arguments, moving that many nodes in that case.
* `C-x w' (info-toggle-wrap) controls how lines wider than the width
of the screen are displayed. If a line is too long, a `$' is
displayed in the rightmost column of the window.
* There are some new variables for controlling the behaviour of Info
interactively. The current list of variables is as follows:
Variable Name Default Value Description
------------- ------------- -----------
`automatic-footnotes' On When "On", footnotes appear and
disappear automatically.
`automatic-tiling' Off When "On", creating of deleting a
window resizes other windows.
`visible-bell' Off If non-zero, try to use a visible bell.
`errors-ring-bell' On If non-zero, errors cause a ring.
`show-index-match' On If non-zero, the portion of the string
matched is highlighted by changing its
case.
`scroll-behaviour' Continuous One of "Continuous", "Next Only", or
"Page Only". "Page Only" prevents you from
scrolling past the bottom or top of a node.
"Next Only" causes the Next or Prev node to
be selected when you scroll past the bottom
or top of a node. "Continous" moves
linearly through the files hierchichal
structure.
`scroll-step' 0 Controls how scrolling is done for you when
the cursor moves out of the current window.
Non-zero means it is the number of lines
you would like the screen to shift. A
value of 0 means to center the line
containing the cursor in the window.
`gc-compressed-files' Off If non-zero means it is okay to reclaim the
file buffer space allocated to a file which
was compressed, if, and only if, that
file's contents do not appear in the node
list of any window.
`ISO-Latin' Off Non-zero means that you are using an ISO
Latin character set. By default, standard
ASCII characters are assumed.
________________________________________
This release of Info is version 2.5 beta.
Changes since 2.4 beta:
* Index (i) and (,) commands fully implemented.
* "configure" script now shipped with Info.
* New function "set-variable" allows users to set various variables.
* User-settable behaviour on end or beginning of node scrolling. This
supercedes the SPC and DEL changes in 2.3 beta.
________________________________________
This release of Info is version 2.4 beta.
Changes since 2.3 beta:
* info-last-node now means move to the last node of this info file.
* info-history-node means move backwards through this window's node history.
* info-first-node moves to the first node in the Info file. This node is
not necessarily "Top"!
* SPC and DEL can select the Next or Prev node after printing an informative
message when pressed at the end/beg of a node.
----------------------------------------
This release of Info is version 2.3 beta.
Changes since 2.2 beta:
* M-x command lines if NAMED_COMMANDS is #defined. Variable in Makefile.
* Screen height changes made quite robust.
* Interactive function "set-screen-height" implements user height changes.
* Scrolling on some terminals is faster now.
* C-l with numeric arguement is fixed.
----------------------------------------
This release of Info is version 2.2 beta.
Changes since 2.0:
* C-g can now interrupt multi-file searches.
* Incremental search is fully implemented.
* Loading large tag tables is much faster now.
* makedoc.c replaces shell script, speeding incremental builds.
* Scrolling in redisplay is implemented.
* Recursive uses of the echo area made more robust.
* Garbage collection of unreferenced nodes.

any interested parties are welcome. If you're a programmer and wish to
contribute, this should get you started. And if you're not a
programmer, you can still make significant contributions by writing test
cases, checking the documentation against the implementation, etc.
This distribution includes the following files, among others:
README This file.
README.dev Texinfo developer information.
INSTALL Texinfo-specific installation notes.
NEWS Summary of new features by release.
INTRODUCTION Brief introduction to the system, and
how to create readable files from the
Texinfo source files in this distribution.
Texinfo documentation files (in ./doc):
texinfo.txi Describes the Texinfo language and many
of the associated tools. It tells how
to use Texinfo to write documentation,
how to use Texinfo mode in GNU Emacs,
TeX, makeinfo, and the Emacs Lisp
Texinfo formatting commands.
info.texi This manual tells you how to use
Info. This document also comes as part of
GNU Emacs. If you do not have Emacs,
you can format this Texinfo source
file with makeinfo or TeX and then
read the resulting Info file with the
standalone Info reader that is part of
this distribution.
info-stnd.texi This manual tells you how to use
the standalone GNU Info reader that is
included in this distribution as C
source (./info).
Printing related files:
doc/texinfo.tex This TeX definitions file tells
the TeX program how to typeset a
Texinfo file into a DVI file ready for
printing.
util/texindex.c This file contains the source for
the `texindex' program that generates
sorted indices used by TeX when
typesetting a file for printing.
util/texi2dvi This is a shell script for
producing an indexed DVI file using
TeX and texindex.
Source files for standalone C programs:
./lib
./makeinfo
./info
Installation files:
Makefile.am What Automake uses to make a Makefile.in.
Makefile.in What `configure' uses to make a Makefile,
created by Automake.
configure.ac What Autoconf uses to create `configure'.
configure Configuration script for local conditions,
created by Autoconf.

README.dev - Texinfo developer information.

Copying and distribution of this file, with or without modification,

notice and this notice are preserved.
The development sources for Texinfo is available through anonymous cvs
at Savannah, see
http://savannah.gnu.org/cvs/?group=texinfo
This distribution uses whatever versions of automake, autoconf, and
gettext are listed in NEWS; usually the latest ones released. If you
are getting the Texinfo sources from cvs, or change the Texinfo
configure.ac, you'll need to have these tools installed to (re)build.
You'll also need help2man. (All of these are available from
ftp://ftp.gnu.org/gnu.)
Here's the order in which to run the tools for a fresh build:
autoheader # creates config.in, not necessarily needed every time
aclocal -I m4 # for a new version of automake
automake
autoconf
configure CFLAGS=-g --enable-maintainer-mode
make
(with arguments to taste, of course.) Or you can run
./bootstrap
instead of the various auto* tools.
One final note: If you would like to contribute to the GNU project by
implementing additional documentation output formats for Texinfo, that
would be great. But please do not write a separate translator texi2foo
for your favorite format foo! That is the hard way to do the job, and
makes extra work in subsequent maintenance, since the Texinfo language
is continually being enhanced and updated. Instead, the best approach
is modify Makeinfo to generate the new format, as it does now for Info,
HTML, XML, and DocBook.

* General:
- @euro{}.
- Support installation of manuals in different languages, along these lines:
. support a LINGUAS file or variable saying which subdirs LL in the
source to descend into (under doc/).
. within each subdir LL, install the info files into $infodir/LL,
and run install-info on $infodir/LL/dir.
. info (both emacs and standalone) should read $infodir/$LANG/dir
as the first dir file, and likewise read info files first from
$infodir/$LANG, before falling back to $infodir.
. consider ways to avoid installing images in both places.
In fact, images probably need to be installed in a subdir
$infodir/MANUAL/ in the first place, to avoid conflicts of having
the same image name in different manuals.
For a test case, see texinfo cvs, with its one translated manual
(info-fr.texi).
From Wojciech Polak.
- Monitor and improve the dir categories in existing manuals,
following the Free Software Directory categories. Much mail to
developers has already been sent, what's needed now is to check new
releases and make sure they are using the right categories.
See the util/dir-example in the Texinfo distribution for our current
recommended categories.
For background, see the thread (which discusses a lot of other
issues too) at
http://mail.gnu.org/pipermail/emacs-devel/2002-10/msg00011.html,
especially
http://mail.gnu.org/archive/html/emacs-devel/2002-10/msg00090.html
http://mail.gnu.org/archive/html/emacs-devel/2002-10/msg00137.html
- Get Info declared as a MIME Content-Type.
- Likewise the `info:' URI scheme; a library consortium has proposed a
completely different purpose for the URI scheme, but I don't know
how to send comments, despite it being a "request for comments". Sigh.
There is mail about this in the bug-texinfo archives:
http://mail.gnu.org/archive/html/bug-texinfo/2003-09/msg00086.html
- Support compressed image files.
- Support reference card creation, perhaps by only paying attention to
sectioning and @def... commands.
- Allow @end (and other?) commands to be indented in the source.
- Test for memory leaks, e.g., with valgrind:
http://developer.kde.org/~sewardj/
- Extend and improve the tests.
* Language:
- @else for the @if... conditionals.
- @xindexterm [def] primary [,secondary [,tertiary]] or some such?
- Allow subitems and `see' and `see also' in indices.
- multicolumn * width to take up `the rest'.
- another table command to take N succeeding items and split them
into M columns (see eplain).
- support bibliographies with BibTeX (see web2c/doc for kludge prototype).
- @flushboth to combine @flushleft and @flushright, for RFC's.
- @part sectioning command.
- @exercise/@answer command for, e.g., gawk.
- Allow @hsep/@vsep at @item, instead of just in template.
- Support automatic line numbering of examples.
- Better macro syntax.
- Better def... command syntax.
- Allow : in node names for info files, for names like
`class::method'. Likewise index entries. A quoting mechanism such
as surrounding node names with SPACE BACKSPACE is probably the best
solution, although this is an incompatible change to Info format, sigh.
- Glossary/general definition support (dumas msg 28 Nov 2003 17:09:57 +0100).
- Add support for other Latin 9 (and Latin 2 and Latin 1) characters.
* Makeinfo:
- Translation of "Appendix" etc. should depend on @doclang not $LANG.
- Try directory of main source file.
- Make makeinfo -E just do macro expansion, avoiding all error checks.
That way, texi2dvi could run makeinfo --iftex -E.
- A detexinfo program, like detex or delatex. This command would
strip all the texinfo commands out, and would be used as a filter on
the way to a speller. An option would be to NOT strip comments out.
makeinfo --no-headers comes close.
- If node name contains an @ command, complain explicitly.
- Use @documentlanguage instead of LANG for many translations.
- HTML: split output by chapter to improve context, per Akim.
Generate dummy files for all nodes for the sake of cross-references.
- HTML: support thumbnails.
- HTML: make images of math, maybe.
- HTML: allow settable background color, table colors and spacing,
<head> meta tags, etc. A la http://texi2html.cvshome.org. In fact:
- HTML: have a library of different CSS styles.
http://mail.gnu.org/archive/html/bug-texinfo/2004-01/msg00025.html
- XML: cannot be loaded directly in a browser; why not?
- Docbook: &euro; and other entities do not work; does anything work?
- Rewrite completely to simplify generation of different formats.
* TeX:
- Use @ as the escape character, and Texinfo syntax generally, in the
table of contents and index files. Eliminate all the crazy
multiple redefinitions of every Texinfo command in different contexts.
- Support input in any encoding and language, via ec or Latin Modern fonts.
- Reasonable way to change fonts from the default (some work has been
done), to allow for PostScript fonts, for example.
- @multitable: handle @hsep and @vsep.
- @multitable: repeat table headings if multiple pages long.
- @multitable: support a heading line concept (<thead> in HTML).
- Introduce new command to change \bindingoffset.
- How about using latex2html to produce HTML?
- Table of contents gets misaligned if there are 10 or more [sub]sections.
- Use url.sty (or something) to allow linebreak of url's.
- Include hyperlink \special's in the DVI output for xdvi, etc.
- PDF: make each letter of the index (A, B, ...) a section in the TOC.
From Carsten Dominik <dominik@astro.uva.nl>.
* Doc:
- Include a complete functional summary, as in a reference card, in
the manual.
- Improve the manuals, especially for makeinfo, standalone info, etc.
- new section on doing dedication pages. See gawk.texi
for an example of doing it in both the tex and info versions.
* Info:
- Regular expression search.
- Full-text search across all info files installed on the system.
- Support character sets other than ISO Latin 1.
- Perhaps comply with LANGUAGE setting on a per-node basis, to allow
incremental translation of Texinfo files.
- Search all nodes of dir file at startup, then can have
INFO-DIR-SEPARATE-GROUPS and other such.
- Better dir file merging.
- Global dir file (as in /etc/conf/dir) and texinfo config file
specifying which info directories to search. From Dale Mellor.
http://mail.gnu.org/mailman/private/gnu-prog-discuss/2003q4/000439.html
- Steal interface ideas from Lynx: number links, use color, etc.
Perhaps code from the pinfo viewer can be reused:
http://zeus.polsl.gliwice.pl/~pborys/.
- More sample .infokey files, so people can choose without writing their own.
- q within help should quit help like C-x 0.
- Incorporate an X-based viewer, perhaps saxinfo or tkinfo
http://www.math.ucsb.edu/~boldt/tkinfo/
- Make "info foo bar" search for bar in foo's index(es) if no menu match.
- Handle M-n, C-u m, and C-u g like Emacs Info (opening new windows).
- Write technical definition of Info format.
* install-info:
- be able to copy the info file to compile-time $infodir, to
simplify by-hand installation.
- also support installing HTML files, etc., along with subsidiary
@image (or other) files. In subdirs. Or something.
- support info dir entries for other than the current info file name;
see comments in menu_item_equal.
- merge features with Debian install-info, so we can have one program.
* texindex:
- read source file (specified by new option) for @documentlanguage
and/or @documentencoding, and change the sorting appropriately.
From: Wojciech Polak, 26 Apr 2003 11:30:59 +0200.
* Distribution:
- generate txi-??.tex from .po's to make translators' jobs easier.
From Akim and Karl E.
Ideas that will not be implemented:
- Process Texinfo files directly instead of converting to Info:
ftp://ftp.cs.berkeley.edu/ucb/people/phelps/tcltk/tkman.tar.Z, which
uses Tcl/Tk 8.0 from ftp.smli.com in the /pub/tcl directory.
From: phelps@ecstasy.CS.Berkeley.EDU (Tom Phelps)
[This has the disadvantage of needing to be updated when the
Texinfo language changes, so don't.]
- Call Ghostscript to get ASCII/jpg output for the @image command.
[makeinfo should not try to be make, or assume it knows how the user
wants to generate images. Too many different methods are possible.]
- Change bars. This is difficult or impossible in TeX,
unfortunately. To do it right requires device driver support.
wdiff or ediff may be all we can do. Merely specifying what should be
changed is not obvious.

# The set of defined variables is at the end of this script.
# Known limitations:
# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer

# known workaround is to choose shorter directory names for the build
# directory and/or the installation directory.
# All known linkers require a `.a' archive for static linking (except M$VC,
# which needs '.lib').

## dummy dependencies for each header file. Too bad gcc doesn't do

Copyright (C) 2002 Free Software Foundation, Inc.
Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved.
This directory contains documentation on the Texinfo system and the TeX
sources needed to process Texinfo sources. We recommend using the
texi2dvi included in this distribution to run a Texinfo manual through
TeX to produce a DVI file.
The .tex files are not installed automatically because TeX installations
vary so widely. Installing them in the wrong place would give a false
sense of security. So, you should simply cp *.tex to the appropriate
place. If your installation follows the TeX Directory Structure
standard (http://tug.org/tds/), this will be the directory
TEXMF/tex/texinfo/ for texinfo.tex, TEXMF/tex/generic/dvips/ for epsf.tex,
and TEXMF/pdftex/plain/misc for pdfcolor.tex. If you use the default
installation paths, TEXMF will be /usr/local/share/texmf. On systems
with TeX preinstalled, as most GNU/Linux distributions offer, TEXMF
will often be something like /usr/share/texmf.
It is also possible to put these .tex files in a `local' place instead
of overwriting existing ones, but this is more complicated. See your TeX
documentation in general and the texmf.cnf file in particular for information.
If you add files to your TeX installations, not just replace existing
ones, you very likely have to update your ls-R file; do this with the
mktexlsr command. In older versions, this was named MakeTeXls-R.
You can get the latest texinfo.tex from
ftp://ftp.gnu.org/gnu/texinfo/texinfo.tex (and all GNU mirrors)
ftp://tug.org/tex/texinfo.tex (and all CTAN mirrors)
or on the FSF machines in /home/gd/gnu/doc/texinfo.tex.
If you have problems with the version in this distribution, please check
for a newer version.
epsf.tex comes with dvips distributions, and you may already have it
installed. The version here is functionally identical but slightly
nicer than the one in dvips574. The changes have been sent to the
epsf.tex maintainer.

%%% docstring = "This file contains TeX macros to include an
%%% Encapsulated PostScript graphic. It works
%%% by finding the bounding box comment,
%%% calculating the correct scale values, and
%%% inserting a vbox of the appropriate size at
%%% the current position in the TeX document.
%%%
%%% To use, simply say
%%%
%%% \input epsf % somewhere early on in your TeX file
%%%
%%% % then where you want to insert a vbox for a figure:
%%% \epsfbox{filename.ps}
%%%
%%% Alternatively, you can supply your own
%%% bounding box by
%%%
%%% \epsfbox[0 0 30 50]{filename.ps}
%%%
%%% This will not read in the file, and will
%%% instead use the bounding box you specify.
%%%
%%% The effect will be to typeset the figure as
%%% a TeX box, at the point of your \epsfbox
%%% command. By default, the graphic will have
%%% its `natural' width (namely the width of
%%% its bounding box, as described in
%%% filename.ps). The TeX box will have depth
%%% zero.
%%%
%%% You can enlarge or reduce the figure by
%%% saying
%%%
%%% \epsfxsize=<dimen> \epsfbox{filename.ps}
%%% or
%%% \epsfysize=<dimen> \epsfbox{filename.ps}
%%%
%%% instead. Then the width of the TeX box will
%%% be \epsfxsize and its height will be scaled
%%% proportionately (or the height will be
%%% \epsfysize and its width will be scaled
%%% proportionately).
%%%
%%% The width (and height) is restored to zero
%%% after each use, so \epsfxsize or \epsfysize
%%% must be specified before EACH use of
%%% \epsfbox.
%%%
%%% A more general facility for sizing is
%%% available by defining the \epsfsize macro.
%%% Normally you can redefine this macro to do
%%% almost anything. The first parameter is
%%% the natural x size of the PostScript
%%% graphic, the second parameter is the
%%% natural y size of the PostScript graphic.
%%% It must return the xsize to use, or 0 if
%%% natural scaling is to be used. Common uses
%%% include:
%%%
%%% \epsfxsize % just leave the old value alone
%%% 0pt % use the natural sizes
%%% #1 % use the natural sizes
%%% \hsize % scale to full width
%%% 0.5#1 % scale to 50% of natural size
%%% \ifnum #1>\hsize\hsize\else#1\fi
%%% % smaller of natural, hsize
%%%
%%% If you want TeX to report the size of the
%%% figure (as a message on your terminal when
%%% it processes each figure), say
%%% `\epsfverbosetrue'.
%%%
%%% If you only want to get the bounding box
%%% extents, without producing any output boxes
%%% or \special{}, then say
%%% \epsfgetbb{filename}. The extents will be
%%% saved in the macros \epsfllx \epsflly
%%% \epsfurx \epsfury in PostScript units of
%%% big points.

%%%
%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 03 Dec 1991 [2.0].
%%% Add version number and date typeout.
%%%
%%% Use \immediate\write16 instead of \message
%%% to ensure output on new line.
%%%
%%% Handle nested EPS files.
%%%
%%% Handle %%BoundingBox: (atend) lines.

%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 09 Dec 1992 [2.2].
%%% Introduce \epsfshow{true,false} and

%%% suppresses the insertion of the PostScript,
%%% and instead just creates an empty box,
%%% which may be handy for rapid prototyping.
%%%
%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 14 Dec 1992 [2.3].
%%% Add \epsfshowfilename{true,false}. When

%%% centered in the figure box.
%%%
%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 20 June 1993 [2.4].
%%% Remove non-zero debug setting of \epsfframemargin,
%%% and change margin handling to preserve EPS image
%%% size and aspect ratio, so that the actual
%%% box is \epsfxsize+\epsfframemargin wide by
%%% \epsfysize+\epsfframemargin high.
%%% Reduce output of \epsfshowfilenametrue to

%%%
%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 13 July 1993 [2.5].

%%% \epsfframe frame lines.
%%%
%%% ---------------------------------------------
%%% Revised by Nelson H. F. Beebe
%%% <beebe@math.utah.edu>, 02 July 1996 [2.6]

PREAMBLE
The purpose of this License is to make a manual, textbook, or other
functional and useful document @dfn{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.
@item
APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be
distributed under the terms of this License. Such a notice grants a
world-wide, royalty-free license, unlimited in duration, to use that
work under the conditions stated herein. The ``Document'', below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as ``you''. You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
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. (Thus, 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. If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero
Invariant Sections. If the Document does not identify any Invariant
Sections then there are none.
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 Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
A ``Transparent'' copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
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, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text. A copy that is not ``Transparent'' is called ``Opaque''.
Examples of suitable formats for Transparent copies include plain
@sc{ascii} without markup, Texinfo input format, La@TeX{} input
format, @acronym{SGML} or @acronym{XML} using a publicly available
@acronym{DTD}, and standard-conforming simple @acronym{HTML},
PostScript or @acronym{PDF} designed for human modification. Examples
of transparent image formats include @acronym{PNG}, @acronym{XCF} and
@acronym{JPG}. Opaque formats include proprietary formats that can be
read and edited only by proprietary word processors, @acronym{SGML} or
@acronym{XML} for which the @acronym{DTD} and/or processing tools are
not generally available, and the machine-generated @acronym{HTML},
PostScript or @acronym{PDF} 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.
A section ``Entitled XYZ'' means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language. (Here XYZ stands for a
specific section name mentioned below, such as ``Acknowledgements'',
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
of such a section when you modify the Document means that it remains a
section ``Entitled XYZ'' according to this definition.
The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
@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.
@item
COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have
printed covers) 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 computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
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.
@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:
@enumerate A
@item
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.
@item
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 fewer than five),
unless they release you from this requirement.
@item
State on the Title page the name of the publisher of the
Modified Version, as the publisher.
@item
Preserve all the copyright notices of the Document.
@item
Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
@item
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.
@item
Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
@item
Include an unaltered copy of this License.
@item
Preserve the section Entitled ``History'', Preserve 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.
@item
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.
@item
For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
the Title of the section, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.
@item
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.
@item
Delete any section Entitled ``Endorsements''. Such a section
may not be included in the Modified Version.
@item
Do not retitle any existing section to be Entitled ``Endorsements'' or
to conflict in title with any Invariant Section.
@item
Preserve any Warranty Disclaimers.
@end enumerate
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
standard.
You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
@item
COMBINING DOCUMENTS
You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled ``History''
in the various original documents, forming one section Entitled
``History''; likewise combine any sections Entitled ``Acknowledgements'',
and any sections Entitled ``Dedications''. You must delete all
sections Entitled ``Endorsements.''
@item
COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
@item
AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an ``aggregate'' if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
@item
TRANSLATION
Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the

.TH INFO 5 "GNU Info" "FSF"
.SH NAME
info \- readable online documentation
.SH DESCRIPTION
The Info file format is an easily-parsable representation for online
documents. It can be read by
.I emacs(1)
and
.I info(1)
among other programs.
.PP
Info files are usually created from
.I texinfo(5)
sources by
.IR makeinfo(1) ,
but can be created from scratch if so desired.
.PP
For a full description of the Texinfo language and associated tools,
please see the Texinfo manual (written in Texinfo itself). Most likely,
running this command from your shell:
.RS
.I info texinfo
.RE
or this key sequence from inside Emacs:
.RS
.I M-x info RET m texinfo RET
.RE
will get you there.
.SH AVAILABILITY
ftp://ftp.gnu.org/pub/gnu/texinfo-<version>.tar.gz
.br
or any GNU mirror site.
.SH "REPORTING BUGS"
Please send bug reports to bug-texinfo@gnu.org,

[\fIOPTION\fR]... \fIFILE\fR...
.SH DESCRIPTION
Run each Texinfo or LaTeX FILE through TeX in turn until all
cross\-references are resolved, building all indices. The directory
containing each FILE is searched for included files. The suffix of FILE
is used to determine its language (LaTeX or Texinfo).
.PP
Makeinfo is used to perform Texinfo macro expansion before running TeX
when needed.

specify the LANG of FILE (LaTeX or Texinfo)
.TP
\fB\-p\fR, \fB\-\-pdf\fR
use pdftex or pdflatex for processing
.TP
\fB\-r\fR, \fB\-\-recode\fR
call recode before TeX to translate input characters
.TP
\fB\-t\fR, \fB\-\-command\fR=\fICMD\fR
insert CMD in copy of input file
.TP
or \fB\-\-texinfo\fR=\fICMD\fR
multiple values accumulate
.PP
The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
TEX (or PDFTEX), TEXINDEX, and THUMBPDF environment variables are used
to run those commands, if they are set. Any CMD strings are added
after @setfilename for Texinfo input, in the first line for LaTeX input.

Info 2.0 is a complete rewrite of the original standalone Info I wrote in
1987, the first program I wrote for rms. That program was something like
my second Unix program ever, and my die-hard machine language coding habits
tended to show through. I found the original Info hard to read and
maintain, and thus decided to write this one.
The rewrite consists of about 12,000 lines of code written in about 12
days. I believe this version of Info to be in much better shape than the
original Info.
Info 2.0 is substantially different from its original standalone
predecessor. It appears almost identical to the GNU Emacs version, but has
the advantages of smaller size, ease of portability, and a built in library
which can be used in other programs (to get or display documentation from
Info files, for example).
A full listing of the commands available in Info can be gotten by typing
`?' while within an Info window. This produces a node in a window which
can be viewed just like any Info node.

Source file syntax
------------------
The source file is a line-based text file with the following
structure:
# comments
# more comments
#info
u prev-line
d next-line
^a invalid # just beep
\ku prev-line
#stop
\kd next-line
q quit # of course!
#echo-area
^a echo-area-beg-of-line
^e echo-area-end-of-line
\kr echo-area-forward
\kl echo-area-backward
\kh echo-area-beg-of-line
\ke echo-area-end-of-line
#var
scroll-step=1
ISO-Latin=Off
Lines starting with '#' are comments, and are ignored. Blank
lines are ignored. Each section is introduced by one of the
following lines:
#info
#echo-area
#var
The sections may occur in any order. Each section may be
omitted completely. If the 'info' section is the first in the
file, its '#info' line may be omitted.
The 'info' and 'echo-area' sections
-----------------------------------
Each line in the 'info' or 'echo-area' sections has the
following syntax:
key-sequence SPACE action-name [ SPACE [ # comment ] ] \n
Where SPACE is one or more white space characters excluding
newline, "action-name" is the name of a GNU Info command,
"comment" is any sequence of characters excluding newline, and
"key-sequence" is a concatenation of one or more key definitions
using the following syntax:
1. A carat ^ followed by one character indicates a single
control character;
2. A backslash \ followed by one, two, or three octal
digits indicates a single character having that ASCII
code;
3. \n indicates a single NEWLINE;
\e indicates a single ESC;
\r indicates a single CR;
\t indicates a single TAB;
\b indicates a single BACKSPACE;
4. \ku indicates the Up Arrow key;
\kd indicates the Down Arrow key;
\kl indicates the Left Arrow key;
\kr indicates the Right Arrow key;
\kP indicates the Page Up (PRIOR) key;
\kN indicates the Page Down (NEXT) key;
\kh indicates the Home key;
\ke indicates the End key;
\kx indicates the DEL key;
\k followed by any other character indicates a single
control-K, and the following character is interpreted
as in rules 1, 2, 3, 5 and 6.
5. \m followed by any sequence defined in rules 1, 2, 3, 4
or 6 indicates the "Meta" modification of that key.
6. A backslash \ followed by any character not described
above indicates that character itself. In particular:
\\ indicates a single backslash \,
\ (backslash-space) indicates a single space,
\^ indicates a single caret ^,
If the following line:
#stop
occurs anywhere in an 'info' or 'echo-area' section, that
indicates to GNU Info to suppress all of its default key
bindings in that context.
The 'var' section
-----------------
Each line in the 'var' section has the following syntax:
variable-name = value \n
Where "variable-name" is the name of a GNU Info variable and
"value" is the value that GNU Info will assign to that variable
when commencing execution. There must be no white space in the
variable name, nor between the variable name and the '='. All
characters immediately following the '=', up to but not
including the terminating newline, are considered to be the
value that will be assigned. In other words, white space
following the '=' is not ignored.
