+1 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 free software 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 on translations can contact the appropriate team.
+
+1.1 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.  Installers may use special
+options at configuration time for changing the default behaviour.  The
+command:
+
+     ./configure --disable-nls
+
+will _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' library
+and will decide to use it.  If not, you may have to to use the
+`--with-libintl-prefix' option to tell `configure' where to look for it.
+
+   Internationalized packages usually have 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.
+
+1.2 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.  If you happen to have the `LC_ALL' or some other
+`LC_xxx' environment variables set, you should unset them before
+setting `LANG', otherwise the setting of `LANG' will not have the
+desired effect.  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 language 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.
+
+1.3 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://translationproject.org/', in the "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 `coordinator translationproject org' 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 skills are praised more than
+programming skills, here.
+
+1.4 Available Packages
+======================
+
+Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of June
+2010.  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
+which it applies should also have been internationalized and
+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.

+   If June 2010 seems to be old, you may fetch a more recent copy of

+
+1.5 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
+`coordinator translationproject org' to make the `.pot' files available
+to the translation teams.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+  dnl $prefix/lib64 and 32-bit libraries go under $prefix/lib. We determine

+  dnl path. If at least one of its elements ends in /lib64 or points to a
+  dnl directory whose absolute pathname ends in /lib64, we assume a 64-bit ABI.

+  dnl $prefix/lib/64 (which is a symlink to either $prefix/lib/sparcv9 or

+# This catalog translates grave accent (0x60) and apostrophe (0x27) to

+# left double quotation mark (U+201C) and right double quotation mark (U+201D).
+#
+# When output to an UTF-8 terminal, the quotation characters appear perfectly.
+# When output to an ISO-8859-1 terminal, the single quotation marks are
