+Notes on the GNU Translation Project
+************************************
+
+   GNU is going international!  The GNU Translation Project is a way to
+get maintainers, translators, and users all together, so that GNU 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 GNU 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.
+
+One advise in advance
+=====================
+
+   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, no
+prior implementation provides as many useful features (such as locale
+alias or message inheritance).  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.
+
+INSTALL Matters
+===============
+
+   Some GNU 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 provides
+usable `catgets' (if using this is selected by the installer) or
+`gettext' functions.  If neither is available, 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 --with-catgets
+     ./configure --disable-nls
+
+will respectively bypass any pre-existing `catgets' or `gettext' to use
+the internationalizing routines provided within this package, enable
+the use of the `catgets' functions (if found on the locale system), 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.
+
+   By default the configuration process will not test for the `catgets'
+function and therefore they will not be used.  The reasons are already
+given above: the emulation on top of `catgets' cannot provide all the
+extensions provided by the GNU `gettext' library.  If you nevertheless
+want to use the `catgets' functions use
+
+     ./configure --with-catgets
+
+to enable the test for `catgets' (this causes no harm if `catgets' is
+not available on your system).  If you really select this option we
+would like to hear about the reasons because we cannot think of any
+good one ourself.
+
+   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
+ISO 639 `LL' two-letter code prior to using the programs in the
+package.  For example, let's suppose that you speak German.  At the
+shell prompt, merely execute `setenv LANG de' (in `csh'),
+`export LANG; LANG=de' (in `sh') or `export LANG=de' (in `bash').  This
+can be done from your `.login' or `.profile' file, once and for all.
+
+   An operating system might already offer message localization for
+many of its programs, while other programs (whether GNU or not) have
+been installed locally with the full capabilities of GNU `gettext'.
+Just using `gettext' extended syntax for `LANG' would break proper
+localization of already available operating system programs.  In this
+case, users should set both `LANGUAGE' and `LANG' variables in their
+environment, as programs using GNU `gettext' give preference to
+`LANGUAGE'.  For example, some Swedish users would rather read
+translations in German than English for when Swedish is not available.
+This is easily accomplished by setting `LANGUAGE' to `sv:de' while
+leaving `LANG' to `sv'.
+
+Translating Teams
+=================
+
+   For the GNU 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, courtesy of Linux
+International.  You may reach your translation team at the address
+`LL@li.org', replacing LL by the two-letter ISO 639 code for your
+language.  Language codes are *not* the same as the country codes given
+in ISO 3166.  The following translation teams exist, as of August 1996:
+
+     Arabic `ar', Chinese `zh', Czech `cs', Danish `da', Dutch `nl',
+     English `en', Esperanto `eo', Finnish `fi', French `fr', German
+     `de', Greek `el', Hebrew `he', Hungarian `hu', Irish `ga', Italian
+     `it', Indonesian `id', Japanese `ja', Korean `ko', Latin `la',
+     Norwegian `no', Persian `fa', Polish `pl', Portuguese `pt',
+     Russian `ru', Slovenian `sl', Spanish `es', Swedish `sv', Telugu
+     `te', Turkish `tr' and Ukrainian `uk'.
+
+For example, you may reach the Chinese translation team by writing to
+`zh@li.org'.
+
+   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 `gnu-translation@gnu.ai.mit.edu' to reach
+the GNU coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology used in GNU.  Proven linguistic skill are praised more
+than programming skill, here.  For the time being, please avoid
+subscribing to the English team unless explicitly invited to do so.
+

+   Some counters in the preceding matrix are higher than the number of

+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and

+lag between the mere existence a PO file and its wide availability in a
+GNU distribution.

INSTALL

-This is a generic INSTALL file for utilities distributions.
-If this package does not come with, e.g., installable documentation or
-data files, please ignore the references to them below.
+Basic Installation
+==================
 
-To compile this package:
+   These are generic installation instructions.
 
-1.  Configure the package for your system.  In the directory that this
-file is in, type `./configure'.  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.
+   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, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
 
-The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation, and
-creates the Makefile(s) (one in each subdirectory of the source
-directory).  In some packages it creates a C header file containing
-system-dependent definitions.  It also creates a file `config.status'
-that you can run in the future to recreate the current configuration.
+   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 at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
 
-Running `configure' takes a minute or two.  While it is running, it
-prints some messages that tell what it is doing.  If you don't want to
-see the messages, run `configure' with its standard output redirected
-to `/dev/null'; for example, `./configure >/dev/null'.
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
 
-To compile the package in a different directory from the one
-containing the source code, 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
-`configure'.  `configure' automatically checks for the source code in
-the directory that `configure' is in and in `..'.  If for some reason
-`configure' is not in the source code directory that you are
-configuring, then it will report that it can't find the source code.
-In that case, run `configure' with the option `--srcdir=DIR', where
-DIR is the directory that contains the source code.
+The simplest way to compile this package is:
 
-By default, `make install' will install the package's files in
-/usr/local/bin, /usr/local/lib, /usr/local/man, etc.  You can specify
-an installation prefix other than /usr/local by giving `configure' the
-option `--prefix=PATH'.  Alternately, you can do so by giving a value
-for the `prefix' variable when you run `make', e.g.,
-	make prefix=/usr/gnu
+  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.
 
-You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If
-you give `configure' the option `--exec_prefix=PATH' or set the
-`make' variable `exec_prefix' to PATH, the package will use PATH as
-the prefix for installing programs and libraries.  Data files and
-documentation will still use the regular prefix.  Normally, all files
-are installed using the regular prefix.
+     Running `configure' takes a while.  While running, it prints some
+     messages telling which features it is checking for.
 
-You can tell `configure' to figure out the configuration for your
-system, and record it in `config.status', without actually configuring
-the package (creating `Makefile's and perhaps a configuration header
-file).  To do this, give `configure' the `--no-create' option.  Later,
-you can run `./config.status' to actually configure the package.  This
-option is useful mainly in `Makefile' rules for updating `config.status'
-and `Makefile'.  You can also give `config.status' the `--recheck'
-option, which makes it re-run `configure' with the same arguments you
-used before.  This is useful if you change `configure'.
+  2. Type `make' to compile the package.
 
-`configure' ignores any other arguments that you give it.
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
 
-If your system requires unusual options for compilation or linking
-that `configure' doesn't know about, you can give `configure' initial
-values for some variables by setting them in the environment.  In
-Bourne-compatible shells, you can do that on the command line like
+  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.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
 this:
-	CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
 
-The `make' variables that you might want to override with environment
-variables when running `configure' are:
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
 
-(For these variables, any value given in the environment overrides the
-value that `configure' would choose:)
-CC		C compiler program.
-		Default is `cc', or `gcc' if `gcc' is in your PATH.
-INSTALL		Program to use to install files.
-		Default is `install' if you have it, `cp' otherwise.
+Compiling For Multiple Architectures
+====================================
 
-(For these variables, any value given in the environment is added to
-the value that `configure' chooses:)
-DEFS		Configuration options, in the form `-Dfoo -Dbar ...'
-LIBS		Libraries to link with, in the form `-lfoo -lbar ...'
+   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 need to do unusual things to compile the package, we encourage
-you to figure out how `configure' could check whether to do them, and
-mail diffs or instructions to the address given in the README so we
-can include them in the next release.
+   If you have to use a `make' that does not supports 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.
 
-2.  Type `make' to compile the package.  If you want, you can override
-the `make' variables CFLAGS and LDFLAGS like this:
+Installation Names
+==================
 
-	make CFLAGS=-O2 LDFLAGS=-s
+   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=PATH'.
 
-3.  If the package comes with self-tests and you want to run them,
-type `make check'.  If you're not sure whether there are any, try it;
-if `make' responds with something like
-	make: *** No way to make target `check'.  Stop.
-then the package does not come with self-tests.
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
 
-4.  Type `make install' to install programs, data files, and
-documentation.
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' 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.
 
-5.  You can remove the program binaries and object files from the
-source directory by typing `make clean'.  To also remove the
-Makefile(s), the header file containing system-dependent definitions
-(if the package uses one), and `config.status' (all the files that
-`configure' created), type `make distclean'.
+   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' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+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 host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+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.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.
 
-The file `configure.in' is used as a template to create `configure' by
-a program called `autoconf'.  You will only need it if you want to
-regenerate `configure' using a newer version of `autoconf'.

+Our units of temporal measurement, from seconds on up to months, are so
+complicated, asymmetrical and disjunctive so as to make coherent mental
+reckoning in time all but impossible.  Indeed, had some tyrannical god
+contrived to enslave our minds to time, to make it all but impossible
+for us to escape subjection to sodden routines and unpleasant surprises,
+he could hardly have done better than handing down our present system.
+It is like a set of trapezoidal building blocks, with no vertical or
+horizontal surfaces, like a language in which the simplest thought
+demands ornate constructions, useless particles and lengthy
+circumlocutions.  Unlike the more successful patterns of language and
+science, which enable us to face experience boldly or at least
+level-headedly, our system of temporal calculation silently and
+persistently encourages our terror of time.
