+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.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. 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
+them 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 prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. 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.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.

+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU 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 that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ 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
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ 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 3 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, see .
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ Copyright (C)
+ This program 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, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+.
+
+ The GNU 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 Lesser General
+Public License instead of this License. But first, please read
+.

+
+ diff: fix a regression when at least one input lacks a newline-at-EOF,
+ and the final hunk plus context-length aligns exactly with the end
+ of the newline-lacking file. Diff would fail to output the required
+ "\ No newline at end of file" line, thus rendering the output invalid.
+ This bug appears to have been introduced by 2006-05-07
+ commit 58d0483b, "(find_identical_ends): Fix huge performance bug...",
+ at least to the extent that reverting that change fixes the bug.
+ Considering the stated effect of that change and lack of metrics,
+ reverting it is not an option, so here we take a more direct approach.
+
+ Given these inputs,
+
+ printf '\n1'>a; printf '\n0\n\n1'>b
+
+ and running diff like this:
+
+ ./diff -U1 a b
+
+ for input file "b", the pointer, files[1].linbuf[4][-1], to
+ the last byte on the final line was mistakenly pointing at the
+ sentinel newline at EOF, rather than at the preceding byte.
+
+ (gdb) p files[1].linbuf[4][-1]
+ $3 = 10 '\n'
+
+ Thus, this test in the final print_1_line call:
+
+ if ((!line_flag || line_flag[0]) && limit[-1] != '\n')
+ fprintf (out, "\n\\ %s\n", _("No newline at end of file"));
+
+ would fail, because limit[-1] (which is files[1].linbuf[4][-1])
+ was mistakenly '\n', rather than the desired '1'.
+
+ My first thought was simply to adjust the final linbuf[line] setting,
+ at the end of io.c's find_and_hash_each_line function function:
+
+ if (p == bufend)
+ - break;
+ + {
+ + if (current->missing_newline)
+ + --linbuf[line];
+ + break;
+ + }
+
+ But that would make diff misbehave with this input
+ (same as above, but with a newline appended to "a"),
+
+ printf '\n1\n'>a; printf '\n0\n\n1'>b
+ ./diff -U1 a b
+
+ due to the block (100 lines above) that is triggered in that case
+ (but not in the both-files-missing-newline case):
+
+ if (p == bufend
+ && current->missing_newline
+ && ROBUST_OUTPUT_STYLE (output_style))
+ {
+ /* This line is incomplete. If this is significant,
+ put the line into buckets[-1]. */
+ if (ignore_white_space < IGNORE_SPACE_CHANGE)
+ bucket = &buckets[-1];
+
+ /* Omit the inserted newline when computing linbuf later. */
+ p--;
+ bufend = suffix_begin = p;
+ }
+
+ Note how "p" is decremented and "bufend" adjusted.
+ When that happens, we certainly don't want to decrement
+ "bufend" yet again.
+
+ Since there is no other way to determine at the end whether "bufend"
+ was already decremented, add a new variable to serve as witness.

+ * src/context.c (print_context_function): Do not print
+ trailing white space in a context header.
+
+2006-05-09 Paul Eggert
+
+ * src/cmp.c (cmp): The previous fix wasn't quite right either, as
+ it mishandled 'cmp A B >/dev/null' when A is shorter than B and
+ differs before A's end-of-file, by outputting a bogus EOF message.
+ Also, it was inefficient if A and B were large.
+
+2006-05-07 Jim Meyering (tiny change)
+
+ Fix bug introduced in 2006-03-09 change:
+ cmp always exits successfully, when stdout is redirected to /dev/null.
+ * src/cmp.c (cmp): When there's a difference, arrange to return nonzero
+ also when comparison_type is the new (from 2006-03-09) type_no_stdout.
+
+2006-05-07 Paul Eggert
+
+ * src/context.c (pr_context_hunk, pr_unidiff_hunk):
+ Prefer fputs or fputc to fprintf, since it's a tad more efficient
+ with unlocked-IO on glibc. Long ago we avoided fputs to
+ work around an ancient SunOS bug, but that's no longer relevant.
+ * src/diff3.c (output_diff3, dotlines, undotlines):
+ (output_diff3_edscript, output_diff3_merge): Likewise.
+ This also avoids a gcc -Wformat-security warning reported
+ by Jim Meyering.
+ * src/ed.c (print_ed_hunk, print_forward_ed_hunk, print_rcs_hunk):
+ Likewise.
+ * src/normal.c (print_normal_hunk): Likewise.
+
+2006-05-06 Paul Eggert
+
+ * src/io.c (find_identical_ends): Fix huge performance bug that I
+ introduced in the 2001-11-25 change: the code to remove the
+ identical suffix also looked at the trailing sentinel, which meant
+ the common suffix length was always incorrectly calculated to be
+ zero. Problem and fix reported by Daniel Hipschman. Instead of
+ his fix, revert to the pre-2001 code.
+
+ * doc/diff.texi: Switch from GFDL 1.1 to 1.2.
+
+2006-03-13 Paul Eggert
+
+ * src/system.h (PARAMS, PROTOTYPES): Remove; no longer needed.
+ (IF_LINT): New macro, to pacify GCC.
+ * src/analyze.c (diag, compareseq): Use IF_LINT.
+ * src/cmp.c (cmp): Likewise.
+ * src/diff3.c (process_diff): Likewise. Also, prefer NULL to 0.

+2006-03-09 Paul Eggert

+ generated and stdout is /dev/null.

+ (AC_FUNC_SETMODE_DOS): Remove.
+ (AC_CONFIG_FILES): Remove m4/Makefile.
+ * doc/diff.texi: Use @- at end of lines that should end in white space,
+ so that Emacs doesn't remove the white space.
+ (diff Options): "diff -NUM" is a pure extension to POSIX, so support
+ it unconditionally.
