+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.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+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 `[email protected]', 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 `[email protected]' 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 July
+2001.  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%.

+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 the GNU General Public License applies to your
+sources from then on if you include `gettext' directly in your
+distribution but since you are writing free software anyway this is no
+restriction.
+
+   Once the sources are changed appropriately and the setup can handle
+to use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`[email protected]' to make the `.pot' files available to
+the translation teams.

+			    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
+  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
-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.
+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 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.
+  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 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.
+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.
 
-  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.
+  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.
 
-  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.
+  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.
 
-  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.
+  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.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"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
+
+		    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.
 
-  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
+  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 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.
+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.
 
-  13. Use with the GNU Affero General Public License.
+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.
 
-  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.
+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.
 
-  14. Revised Versions of this License.
+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.

-the GNU General Public License from time to time.  Such new versions will

+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 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.

+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.
 
-  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.
+  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.

+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, 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').
+
+   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.
+
+   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'.
+
+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.  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=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+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 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.
+
+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=PATH'.
+
+   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.
+
+   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.
+
+   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.  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.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

-Packaging hints for binary package distributors
-===============================================
-
-Although the source of the bison package comes as a single package,
-in distributions of binary packages the installed files should
-be split into two packages:
-
-   bison-runtime
-        Contents: Runtime libraries and programs.
-        Audience: Anyone who wants to run internationalized programs
-                  that contain Bison-generated parsers.
-
-   bison
-        Contents: Tools and documentation for developers that use Bison.
-        Audience: Anyone who wants to develop programs that use parsers.
-        Dependencies: requires bison-runtime.
-
-The 'bison-runtime' binary package is much smaller than the 'bison'
-binary package.  It should be included in any distribution that
-contains localized programs that use the diagnostics contained in
-Bison-generated parsers.
-
-If you want to install both packages at the same time, you simply do
-at the toplevel directory:
-
-      ./configure
-      make
-      make install
-
-After installation, the file
-
-      $prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
-
-belongs to the bison-runtime package; all other installed files belong
-to the bison package.

-This package contains the GNU Bison parser generator.
+This directory contains the Bison parser generator.
 
-* Installation
-** Build
-See the file INSTALL for generic compilation and installation
-instructions.
+See the file INSTALL for compilation and installation instructions.
+See the file doc/FAQ for frequently asked questions.
 
-Bison requires GNU m4 1.4.6 or later.  See:
+It was once true that, when installing Bison on Sequent (or Pyramid?)
+systems, you had to be in the Berkeley universe.  This may no longer
+be true; we have no way to tell.
 
-      ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
+On VMS, you will probably have to create Makefile from Makefile.in by
+hand.  Remember to do `SET COMMAND BISON' to install the data in
+`BISON.CLD'.
 
-** Internationalization
-Bison supports two catalogues: one for Bison itself (i.e., for the
-maintainer-side parser generation), and one for the generated parsers
-(i.e., for the user-side parser execution).  The requirements between
-both differ: bison needs ngettext, the generated parsers do not.  To
-simplify the build system, neither are installed if ngettext is not
-supported, even if generated parsers could have been localized.  See
-http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
-more details.
+VMS and MS-DOS builds are probably broken right now.  If you are able
+to build Bison on either platform and you need to make changes to do
+so, please submit those changes as a bug report.
 
-* Questions
-See the section FAQ in the documentation (doc/bison.info) for

-This file attempts to describe the rules to use when hacking Bison.
-Don't put this file into the distribution.
-
-Everything related to the development of Bison is on Savannah:

-
-
-* Administrivia
-
-** If you incorporate a change from somebody on the net:
-First, if it is a large change, you must make sure they have signed
-the appropriate paperwork.  Second, be sure to add their name and
-email address to THANKS.
-
-** If a change fixes a test, mention the test in the commit message.
-
-** Bug reports
-If somebody reports a new bug, mention his name in the commit message
-and in the test case you write.  Put him into THANKS.
-
-The correct response to most actual bugs is to write a new test case
-which demonstrates the bug.  Then fix the bug, re-run the test suite,
-and check everything in.
-
-
-* Hacking
-
-** Visible changes
-Which include serious bug fixes, must be mentioned in NEWS.
-
-** Translations
-Only user visible strings are to be translated: error messages, bits
-of the .output file etc.  This excludes impossible error messages
-(comparable to assert/abort), and all the --trace output which is
-meant for the maintainers only.
-
-** Horizontal tabs
-Do not add horizontal tab characters to any file in Bison's repository
-except where required.  For example, do not use tabs to format C code.
-However, make files, ChangeLog, and some regular expressions require
-tabs.  Also, test cases might need to contain tabs to check that Bison
-properly processes tabs in its input.
-
-
-* Working from the repository
-
-These notes intend to help people working on the checked-out sources.
-These requirements do not apply when building from a distribution tarball.
-
-** Requirements
-
-We've opted to keep only the highest-level sources in the repository.  This
-eases our maintenance burden, (fewer merges etc.), but imposes more
-requirements on anyone wishing to build from the just-checked-out sources.
-For example, you have to use the latest stable versions of the maintainer
-tools we depend upon, including:
-
-- Autoconf <http://www.gnu.org/software/autoconf/>
-- Automake <http://www.gnu.org/software/automake/>
-- Flex <http://www.gnu.org/software/flex/>
-- Gettext <http://www.gnu.org/software/gettext/>
-- Graphviz <http://www.graphviz.org>
-- Gzip <http://www.gnu.org/software/gzip/>
-- Help2man <http://www.gnu.org/software/help2man/>
-- Perl <http://www.cpan.org/>
-- Rsync <http://samba.anu.edu.au/rsync/>
-- Tar <http://www.gnu.org/software/tar/>
-- Texinfo <http://www.gnu.org/software/texinfo/>
-
-Valgrind <http://valgrind.org/> is also highly recommended, if it supports
-your architecture.
-
-If you're using a GNU/Linux distribution, the easiest way to install the
-above packages depends on your system.  The following shell command should
-work for Debian-based systems such as Ubuntu:
-
-  sudo apt-get install \
-    autoconf automake autopoint flex graphviz help2man texinfo valgrind
-
-Bison is written using Bison grammars, so there are bootstrapping issues.
-The bootstrap script attempts to discover when the C code generated from the
-grammars is out of date, and to bootstrap with an out-of-date version of the
-C code, but the process is not foolproof.  Also, you may run into similar
-problems yourself if you modify Bison.
-
-Only building the initial full source tree will be a bit painful.  Later,
-after synchronizing from the repository a plain 'make' should be sufficient.
-Note, however, that when gnulib is updated, running './bootstrap' again
-might be needed.
-
-** First checkout
-
-Obviously, if you are reading these notes, you did manage to check out
-this package from the repository.  For the record, you will find all the
-relevant information on:
-
-        http://savannah.gnu.org/git/?group=bison
-
-Bison uses Git submodules: subscriptions to other Git repositories.
-In particular it uses gnulib, the GNU portability library.  To ask Git
-to perform the first checkout of the submodules, run
-
-       $ git submodule update --init
-
-Git submodule support is weak before versions 1.6 and later, upgrade Git if
-your version is older.
-
-The next step is to get other files needed to build, which are
-extracted from other source packages:
-
-        $ ./bootstrap
-
-If it fails with missing symbols (e.g., "error: possibly undefined macro:
-AC_PROG_GNU_M4"), you are likely to have forgotten the submodule
-initialization part.  Otherwise, there you are!  Just
-
-        $ ./configure
-        $ make
-        $ make check
-
-At this point, there should be no difference between your local copy,
-and the master copy:
-
-        $ git diff
-
-should output no difference.
-
-Enjoy!
-
-** Updating
-
-The use of submodules make things somewhat different because git does
-not support recursive operations: submodules must be taken care of
-explicitly by the user.
-
-*** Updating Bison
-
-If you pull a newer version of a branch, say via "git pull", you might
-import requests for updated submodules.  A simple "git diff" will
-reveal if the current version of the submodule (i.e., the actual
-contents of the gnulib directory) and the current request from the
-subscriber (i.e., the reference of the version of gnulib that the
-Bison repository requests) differ.  To upgrade the submodules (i.e.,
-to check out the version that is actually requested by the subscriber,
-run "git submodule update".
-
-        $ git pull
-        $ git submodule update
-
-*** Updating a submodule
-To update a submodule, say gnulib, do as follows:
-
-Get the most recent version of the master branch from git.
-
-        $ cd gnulib
-        $ git fetch
-        $ git checkout -b master --track origin/master
-
-Make sure Bison can live with that version of gnulib.
-
-        $ cd ..
-        $ ./bootstrap
-        $ make distcheck
-
-Register your changes.
-
-        $ git checkin ...
-
-For a suggestion of what gnulib commit might be stable enough for a
-formal release, see the ChangeLog in the latest gnulib snapshot at:
-
-        http://erislabs.net/ianb/projects/gnulib/
-
-The Autoconf files we use are currently:
-
-        m4/m4.m4
-        lib/m4sugar/m4sugar.m4
-        lib/m4sugar/foreach.m4
-
-These files don't change very often in Autoconf, so it should be
-relatively straight-forward to examine the differences in order to
-decide whether to update.
-
-* Test suite
-
-** make check
-Use liberally.
-
-** TESTSUITEFLAGS
-
-The default is for make check to run all tests sequentially. This can be
-very time consumming when checking repeatedly or on slower setups. This can
-be sped up in two ways:
-
-Using -j, in a make-like fashion, for example:
-  $ make check TESTSUITEFLAGS='-j8'
-
-Running only the tests of a certain category, as specified in the AT files
-with AT_KEYWORDS([[category]]). Categories include:
-  - c++, for c++ parsers
-  - deprec, for tests concerning deprecated constructs.
-  - glr, for glr parsers
-  - java, for java parsers
-  - report, for automaton dumps
-
-To run a specific set of tests, use -k (for "keyword"). For example:
-  $ make check TESTSUITEFLAGS='-k c++'
-
-Both can be combined.
-
-** Typical errors
-If the test suite shows failures such as the following one
-
-  .../bison/lib/getopt.h:196:8: error: redefinition of 'struct option'
-  /usr/include/getopt.h:54:8: error: previous definition of 'struct option'
-
-it probably means that some file was compiled without
-AT_DATA_SOURCE_PROLOGUE.  This error is due to the fact that our -I options
-pick up gnulib's replacement headers, such as getopt.h, and this will go
-wrong if config.h was not included first.
-
-See tests/local.at for details.
-
-** make maintainer-check-valgrind
-This target uses valgrind both to check bison, and the generated parsers.
-
-This is not mature on Mac OS X.  First, Valgrind does support the way bison
-calls m4, so Valgrind cannot be used to check bison on Mac OS X.
-
-Second, there are many errors that come from the platform itself, not from
-bison.  build-aux/darwin11.4.0.valgrind addresses some of them.
-
-Third, valgrind issues warnings such as:
-
-  --99312:0:syswrap- WARNING: Ignoring sigreturn( ..., UC_RESET_ALT_STACK );
-
-which cause the test to fail uselessly.  It is hard to ignore these errors
-with a major overhaul of the way instrumentation is performed in the test
-suite.  So currently, do not try to run valgrind on Mac OS X.
-
-** Release checks
-Try to run the test suite with more severe conditions before a
-release:
-
-- Configure the package with --enable-gcc-warnings, so that one checks
-  that 1. Bison compiles cleanly, 2. the parsers it produces compile
-  cleanly too.
-
-- Maybe build with -DGNULIB_POSIXCHECK, which suggests gnulib modules
-  that can fix portability issues.  See if you really want to pay
-  attention to its warnings; there's no need to obey blindly to it
-  (<http://lists.gnu.org/archive/html/bison-patches/2012-05/msg00057.html>).
-
-- Check with "make syntax-check" if there are issues diagnosed by
-  gnulib.
-
-- run "make maintainer-check" which:
-  - runs "valgrind -q bison" to run Bison under Valgrind.
-  - runs the parsers under Valgrind.
-  - runs the test suite with G++ as C compiler...
-
-- run "make maintainer-push-check", which runs "make maintainer-check"
-  while activating the push implementation and its pull interface wrappers
-  in many test cases that were originally written to exercise only the
-  pull implementation.  This makes certain the push implementation can
-  perform every task the pull implementation can.
-
-- run "make maintainer-xml-check", which runs "make maintainer-check"
-  while checking Bison's XML automaton report for every working grammar
-  passed to Bison in the test suite.  The check just diffs the output of
-  Bison's included XSLT style sheets with the output of --report=all and
-  --graph.
-
-- running "make maintainer-release-check" takes care of running
-  maintainer-check, maintainer-push-check and maintainer-xml-check.
-
-- Change tests/atlocal/CFLAGS to add your preferred options.  For
-  instance, "-traditional" to check that the parsers are K&R.  Note
-  that it does not make sense for glr.c, which should be ANSI, but
-  currently is actually GNU C, nor for lalr1.cc.
-
-- Test with a very recent version of GCC for both C and C++.  Testing
-  with older versions that are still in use is nice too.
-
-
-* Release Procedure
-This section needs to be updated to take into account features from
-gnulib.  In particular, be sure to read README-release.
-
-** Update the submodules.  See above.
-
-** Update maintainer tools, such as Autoconf.  See above.
-
-** Try to get the *.pot files to the Translation Project at least one
-week before a stable release, to give them time to translate them.
-Before generating the *.pot files, make sure that po/POTFILES.in and
-runtime-po/POTFILES.in list all files with translatable strings.
-This helps: grep -l '\<_(' *
-
-** Tests
-See above.
-
-** Update the foreign files
-Running "./bootstrap" in the top level should update them all for you.
-This covers PO files too.  Sometimes a PO file contains problems that
-causes it to be rejected by recent Gettext releases; please report
-these to the Translation Project.
-
-** Update README
-Make sure the information in README is current.  Most notably, make sure
-it recommends a version of GNU M4 that is compatible with the latest
-Bison sources.
-
-** Check copyright years.
-We update years in copyright statements throughout Bison once at the
-start of every year by running "make update-copyright".  However, before
-a release, it's good to verify that it's actually been run.  Besides the
-copyright statement for each Bison file, check the copyright statements
-that the skeletons insert into generated parsers, and check all
-occurrences of PACKAGE_COPYRIGHT_YEAR in configure.ac.
-
-** Update NEWS, commit and tag.
-See do-release-commit-and-tag in README-release.  For a while, we used
-beta names such as "2.6_rc1".  Now that we use gnulib in the release
-procedure, we must use "2.5.90", which has the additional benefit of
-being properly sorted in "git tag -l".
-
-** make alpha, beta, or stable
-See README-release.
-
-** Upload
-There are two ways to upload the tarballs to the GNU servers: using
-gnupload (from gnulib), or by hand.  Obviously prefer the former.  But
-in either case, be sure to read the following paragraph.
-
-*** Setup
-You need "gnupg".
-
-Make sure your public key has been uploaded at least to
-keys.gnupg.net.  You can upload it with:
-
-  gpg --keyserver keys.gnupg.net --send-keys F125BDF3
-
-where F125BDF3 should be replaced with your key ID.
-
-*** Using gnupload
-You need "ncftp".
-
-At the end "make stable" (or alpha/beta) will display the procedure to
-run.  Just copy and paste it in your shell.
-
-*** By hand
-
-The generic GNU upload procedure is at:
-
-  http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads
-
-Follow the instructions there to register your information so you're permitted
-to upload.
-
-Here's a brief reminder of how to roll the tarballs and upload them:
-
-*** make distcheck
-*** gpg -b bison-2.3b.tar.gz
-*** In a file named "bison-2.3b.tar.gz.directive", type:
-
-      version: 1.1
-      directory: bison
-      filename: bison-2.3b.tar.gz
-
-*** gpg --clearsign bison-2.3b.tar.gz.directive
-*** ftp ftp-upload.gnu.org # Log in as anonymous.
-*** cd /incoming/alpha # cd /incoming/ftp for full release.
-*** put bison-2.3b.tar.gz # This can take a while.
-*** put bison-2.3b.tar.gz.sig
-*** put bison-2.3b.tar.gz.directive.asc
-*** Repeat all these steps for bison-2.3b.tar.xz.
-
-** Update Bison manual on www.gnu.org.
-
-*** You need a non-anonymous checkout of the web pages directory.
-
-  $ cvs -d [email protected]:/web/bison checkout bison
-
-*** Get familiar with the instructions for web page maintainers.
-http://www.gnu.org/server/standards/readme_index.html
-http://www.gnu.org/server/standards/README.software.html
-especially the note about symlinks.
-
-*** Build the web pages.
-Assuming BISON_CHECKOUT refers to a checkout of the Bison dir, and
-BISON_WWW_CHECKOUT refers to the web directory created above, do:
-
-  $ cd $BISON_CHECKOUT/doc
-  $ make stamp-vti
-  $ ../build-aux/gendocs.sh -o "$BISON_WWW_CHECKOUT/manual" \
-    bison "Bison - GNU parser generator"
-  $ cd $BISON_WWW_CHECKOUT
-
-Verify that the result looks sane.
-
-*** Commit the modified and the new files.
-
-*** Remove old files.
-Find the files which have not been overwritten (because they belonged to
-sections that have been removed or renamed):
-
-   $ cd manual/html_node
-   $ ls -lt
-
-Remove these files and commit their removal to CVS.  For each of these
-files, add a line to the file .symlinks.  This will ensure that
-hyperlinks to the removed files will redirect to the entire manual; this
-is better than a 404 error.
-
-There is a problem with 'index.html' being written twice (once for POSIX
-function 'index', once for the table of contents); you can ignore this
-issue.
-
-** Announce
-The "make stable" (or alpha/beta) command just created a template,
-$HOME/announce-bison-X.Y.  Otherwise, to generate it, run:
-
-  make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement
-
-where alpha can be replaced by beta or stable and F125BDF3 should be
-replaced with your key ID.
-
-Complete/fix the announcement file.  The generated list of recipients
-([email protected], [email protected], [email protected],
-[email protected], and [email protected]) is
-appropriate for a stable release or a "serious beta".  For any other
-release, drop at least [email protected].  For an example of how to
-fill out the rest of the template, search the mailing list archives
-for the most recent release announcement.
-
-For a stable release, send the same announcement on the comp.compilers
-newsgroup by sending email to [email protected].  Do not make any Cc as
-the moderator will throw away anything cross-posted or Cc'ed.  It really
-needs to be a separate message.
-
-** Prepare NEWS
-So that developers don't accidentally add new items to the old NEWS
-entry, create a new empty entry in line 3 (without the two leading
-spaces):
-
-  * Noteworthy changes in release ?.? (????-??-??) [?]
-
-Push these changes.

TODO

@@ -1,387 +0,0 @@
-* Short term
-** Graphviz display code thoughts
-The code for the --graph option is over two files: print_graph, and
-graphviz. This is because Bison used to also produce VCG graphs, but since
-this is no longer true, maybe we could consider these files for fusion.
-
-An other consideration worth noting is that print_graph.c (correct me if I
-am wrong) should contain generic functions, whereas graphviz.c and other
-potential files should contain just the specific code for that output
-format. It will probably prove difficult to tell if the implementation is
-actually generic whilst only having support for a single format, but it
-would be nice to keep stuff a bit tidier: right now, the construction of the
-bitset used to show reductions is in the graphviz-specific code, and on the
-opposite side we have some use of \l, which is graphviz-specific, in what
-should be generic code.
-
-Little effort seems to have been given to factoring these files and their
-rint{,-xml} counterpart. We would very much like to re-use the pretty format
-of states from .output for the graphs, etc.
-
-Also, the underscore in print_graph.[ch] isn't very fitting considering the
-dashes in the other filenames.
-
-Since graphviz dies on medium-to-big grammars, maybe consider an other tool?
-
-** push-parser
-Check it too when checking the different kinds of parsers.  And be
-sure to check that the initial-action is performed once per parsing.
-
-** m4 names
-b4_shared_declarations is no longer what it is.  Make it
-b4_parser_declaration for instance.
-
-** yychar in lalr1.cc
-There is a large difference bw maint and master on the handling of
-yychar (which was removed in lalr1.cc).  See what needs to be
-back-ported.
-
-
-    /* User semantic actions sometimes alter yychar, and that requires
-       that yytoken be updated with the new translation.  We take the
-       approach of translating immediately before every use of yytoken.
-       One alternative is translating here after every semantic action,
-       but that translation would be missed if the semantic action
-       invokes YYABORT, YYACCEPT, or YYERROR immediately after altering
-       yychar.  In the case of YYABORT or YYACCEPT, an incorrect
-       destructor might then be invoked immediately.  In the case of
-       YYERROR, subsequent parser actions might lead to an incorrect
-       destructor call or verbose syntax error message before the
-       lookahead is translated.  */
-
-    /* Make sure we have latest lookahead translation.  See comments at
-       user semantic actions for why this is necessary.  */
-    yytoken = yytranslate_ (yychar);
-
-
-** stack.hh
-Get rid of it.  The original idea is nice, but actually it makes
-the code harder to follow, and uselessly different from the other
-skeletons.
-
-** Get rid of fake #lines [Bison: ...]
-Possibly as simple as checking whether the column number is nonnegative.
-
-I have seen messages like the following from GCC.
-
-<built-in>:0: fatal error: opening dependency file .deps/libltdl/argz.Tpo: No such file or directory
-
-
-** Discuss about %printer/%destroy in the case of C++.
-It would be very nice to provide the symbol classes with an operator<<
-and a destructor.  Unfortunately the syntax we have chosen for
-%destroy and %printer make them hard to reuse.  For instance, the user
-is invited to write something like
-
-   %printer { debug_stream() << $$; } <my_type>;
-
-which is hard to reuse elsewhere since it wants to use
-"debug_stream()" to find the stream to use.  The same applies to
-%destroy: we told the user she could use the members of the Parser
-class in the printers/destructors, which is not good for an operator<<
-since it is no longer bound to a particular parser, it's just a
-(standalone symbol).
-
-** Rename LR0.cc
-as lr0.cc, why upper case?
-
-* Various
-** YYERRCODE
-Defined to 256, but not used, not documented.  Probably the token
-number for the error token, which POSIX wants to be 256, but which
-Bison might renumber if the user used number 256.  Keep fix and doc?
-Throw away?
-
-Also, why don't we output the token name of the error token in the
-output?  It is explicitly skipped:
-
-      /* Skip error token and tokens without identifier.  */
-      if (sym != errtoken && id)
-
-Of course there are issues with name spaces, but if we disable we have
-something which seems to be more simpler and more consistent instead
-of the special case YYERRCODE.
-
-   enum yytokentype {
-     error = 256,
-     // ...
-   };
-
-
-We could (should?) also treat the case of the undef_token, which is
-numbered 257 for yylex, and 2 internal.  Both appear for instance in
-toknum:
-
-  const unsigned short int
-  parser::yytoken_number_[] =
-  {
-       0,   256,   257,   258,   259,   260,   261,   262,   263,   264,
-
-while here
-
-   enum yytokentype {
-     TOK_EOF = 0,
-     TOK_EQ = 258,
-
-so both 256 and 257 are "mysterious".
-
-  const char*
-  const parser::yytname_[] =
-  {
-  "\"end of command\"", "error", "$undefined", "\"=\"", "\"break\"",
-
-
-** yychar == yyempty_
-The code in yyerrlab reads:
-
-      if (yychar <= YYEOF)
-        {
-          /* Return failure if at end of input.  */
-          if (yychar == YYEOF)
-            YYABORT;
-        }
-
-There are only two yychar that can be <= YYEOF: YYEMPTY and YYEOF.
-But I can't produce the situation where yychar is YYEMPTY here, is it
-really possible?  The test suite does not exercise this case.
-
-This shows that it would be interesting to manage to install skeleton
-coverage analysis to the test suite.
-
-* From lalr1.cc to yacc.c
-** Single stack
-Merging the three stacks in lalr1.cc simplified the code, prompted for
-other improvements and also made it faster (probably because memory
-management is performed once instead of three times).  I suggest that
-we do the same in yacc.c.
-
-** yysyntax_error
-The code bw glr.c and yacc.c is really alike, we can certainly factor
-some parts.
-
-
-* Report
-
-** Figures
-Some statistics about the grammar and the parser would be useful,
-especially when asking the user to send some information about the
-grammars she is working on.  We should probably also include some
-information about the variables (I'm not sure for instance we even
-specify what LR variant was used).
-
-**  GLR
-How would Paul like to display the conflicted actions?  In particular,
-what when two reductions are possible on a given lookahead token, but one is
-part of $default.  Should we make the two reductions explicit, or just
-keep $default?  See the following point.
-
-** Disabled Reductions
-See 'tests/conflicts.at (Defaulted Conflicted Reduction)', and decide
-what we want to do.
-
-** Documentation
-Extend with error productions.  The hard part will probably be finding
-the right rule so that a single state does not exhibit too many yet
-undocumented ''features''.  Maybe an empty action ought to be
-presented too.  Shall we try to make a single grammar with all these
-features, or should we have several very small grammars?
-
-** --report=conflict-path
-Provide better assistance for understanding the conflicts by providing
-a sample text exhibiting the (LALR) ambiguity.  See the paper from
-DeRemer and Penello: they already provide the algorithm.
-
-** Statically check for potential ambiguities in GLR grammars.  See
-<http://www.i3s.unice.fr/~schmitz/papers.html#expamb> for an approach.
-
-
-* Extensions
-
-** $-1
-We should find a means to provide an access to values deep in the
-stack.  For instance, instead of
-
-        baz: qux { $$ = $<foo>-1 + $<bar>0 + $1; }
-
-we should be able to have:
-
-  foo($foo) bar($bar) baz($bar): qux($qux) { $baz = $foo + $bar + $qux; }
-
-Or something like this.
-
-** %if and the like
-It should be possible to have %if/%else/%endif.  The implementation is
-not clear: should it be lexical or syntactic.  Vadim Maslow thinks it
-must be in the scanner: we must not parse what is in a switched off
-part of %if.  Akim Demaille thinks it should be in the parser, so as
-to avoid falling into another CPP mistake.
-
-** XML Output
-There are couple of available extensions of Bison targeting some XML
-output.  Some day we should consider including them.  One issue is
-that they seem to be quite orthogonal to the parsing technique, and
-seem to depend mostly on the possibility to have some code triggered
-for each reduction.  As a matter of fact, such hooks could also be
-used to generate the yydebug traces.  Some generic scheme probably
-exists in there.

-XML output for GNU Bison and gcc
-   http://www.cs.may.ie/~jpower/Research/bisonXML/
-
-XML output for GNU Bison
-   http://yaxx.sourceforge.net/
-
-* Unit rules
-Maybe we could expand unit rules, i.e., transform
-
-        exp: arith | bool;
-        arith: exp '+' exp;
-        bool: exp '&' exp;
-
-into
-
-        exp: exp '+' exp | exp '&' exp;
-
-when there are no actions.  This can significantly speed up some
-grammars.  I can't find the papers.  In particular the book 'LR
-parsing: Theory and Practice' is impossible to find, but according to
-'Parsing Techniques: a Practical Guide', it includes information about
-this issue.  Does anybody have it?
-
-
-
-* Documentation
-
-** History/Bibliography
-Some history of Bison and some bibliography would be most welcome.
-Are there any Texinfo standards for bibliography?
-
-* Coding system independence
-Paul notes:
-
-        Currently Bison assumes 8-bit bytes (i.e. that UCHAR_MAX is
-        255).  It also assumes that the 8-bit character encoding is
-        the same for the invocation of 'bison' as it is for the
-        invocation of 'cc', but this is not necessarily true when
-        people run bison on an ASCII host and then use cc on an EBCDIC
-        host.  I don't think these topics are worth our time
-        addressing (unless we find a gung-ho volunteer for EBCDIC or
-        PDP-10 ports :-) but they should probably be documented
-        somewhere.
-
-        More importantly, Bison does not currently allow NUL bytes in
-        tokens, either via escapes (e.g., "x\0y") or via a NUL byte in
-        the source code.  This should get fixed.
-
-* Broken options ?
-** %token-table
-** Skeleton strategy
-Must we keep %token-table?
-
-* Precedence
-
-** Partial order
-It is unfortunate that there is a total order for precedence.  It
-makes it impossible to have modular precedence information.  We should
-move to partial orders (sounds like series/parallel orders to me).
-
-** RR conflicts
-See if we can use precedence between rules to solve RR conflicts.  See
-what POSIX says.
-
-
-* $undefined
-From Hans:
-- If the Bison generated parser experiences an undefined number in the
-character range, that character is written out in diagnostic messages, an
-addition to the $undefined value.
-
-Suggest: Change the name $undefined to undefined; looks better in outputs.
-
-
-* Default Action
-From Hans:
-- For use with my C++ parser, I transported the "switch (yyn)" statement
-that Bison writes to the bison.simple skeleton file. This way, I can remove
-the current default rule $$ = $1 implementation, which causes a double
-assignment to $$ which may not be OK under C++, replacing it with a
-"default:" part within the switch statement.
-
-Note that the default rule $$ = $1, when typed, is perfectly OK under C,
-but in the C++ implementation I made, this rule is different from
-$<type_name>$ = $<type_name>1. I therefore think that one should implement
-a Bison option where every typed default rule is explicitly written out
-(same typed ruled can of course be grouped together).
-
-* Pre and post actions.
-From: Florian Krohm <[email protected]>
-Subject: YYACT_EPILOGUE
-To: [email protected]
-X-Sent: 1 week, 4 days, 14 hours, 38 minutes, 11 seconds ago
-
-The other day I had the need for explicitly building the parse tree. I
-used %locations for that and defined YYLLOC_DEFAULT to call a function
-that returns the tree node for the production. Easy. But I also needed
-to assign the S-attribute to the tree node. That cannot be done in
-YYLLOC_DEFAULT, because it is invoked before the action is executed.
-The way I solved this was to define a macro YYACT_EPILOGUE that would
-be invoked after the action. For reasons of symmetry I also added
-YYACT_PROLOGUE. Although I had no use for that I can envision how it
-might come in handy for debugging purposes.
-All is needed is to add
-
-#if YYLSP_NEEDED
-    YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen, yyloc, (yylsp - yylen));
-#else
-    YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen);
-#endif
-
-at the proper place to bison.simple. Ditto for YYACT_PROLOGUE.
-
-I was wondering what you think about adding YYACT_PROLOGUE/EPILOGUE
-to bison. If you're interested, I'll work on a patch.
-
-* Better graphics
-Equip the parser with a means to create the (visual) parse tree.
-
-* Complaint submessage indentation.
-We already have an implementation that works fairly well for named
-reference messages, but it would be nice to use it consistently for all
-submessages from Bison.  For example, the "previous definition"
-submessage or the list of correct values for a %define variable might
-look better with indentation.
-
-However, the current implementation makes the assumption that the
-location printed on the first line is not usually much shorter than the
-locations printed on the submessage lines that follow.  That assumption
-may not hold true as often for some kinds of submessages especially if

-This directory contains data needed by Bison.
-
-* Skeletons
-Bison skeletons: the general shapes of the different parser kinds,
-that are specialized for specific grammars by the bison program.
-
-Currently, the supported skeletons are:
-
-- yacc.c
-  It used to be named bison.simple: it corresponds to C Yacc
-  compatible LALR(1) parsers.
-
-- lalr1.cc
-  Produces a C++ parser class.
-
-- lalr1.java
-  Produces a Java parser class.
-
-- glr.c
-  A Generalized LR C parser based on Bison's LALR(1) tables.
-
-- glr.cc
-  A Generalized LR C++ parser.  Actually a C++ wrapper around glr.c.
-
-These skeletons are the only ones supported by the Bison team.
-Because the interface between skeletons and the bison program is not
-finished, *we are not bound to it*.  In particular, Bison is not
-mature enough for us to consider that "foreign skeletons" are
-supported.
-
-* m4sugar
-This directory contains M4sugar, sort of an extended library for M4,
-which is used by Bison to instantiate the skeletons.
-
-* xslt
-This directory contains XSLT programs that transform Bison's XML output
-into various formats.
-
-- bison.xsl
-  A library of routines used by the other XSLT programs.
-
-- xml2dot.xsl
-  Conversion into GraphViz's dot format.
-
-- xml2text.xsl
-  Conversion into text.
-
-- xml2xhtml.xsl
-  Conversion into XHTML.

-# This skeleton produces a C++ class that encapsulates a C glr parser.
-# This is in order to reduce the maintenance burden.  The glr.c
-# skeleton is clean and pure enough so that there are no real
-# problems.  The C++ interface is the same as that of lalr1.cc.  In
-# fact, glr.c can replace yacc.c without the user noticing any
-# difference, and similarly for glr.cc replacing lalr1.cc.
-#
-# The passing of parse-params
-#
-#   The additional arguments are stored as members of the parser
-#   object, yyparser.  The C routines need to carry yyparser
-#   throughout the C parser; that's easy: make yyparser an
-#   additional parse-param.  But because the C++ skeleton needs to
-#   know the "real" original parse-param, we save them
-#   (b4_parse_param_orig).  Note that b4_parse_param is overquoted
-#   (and c.m4 strips one level of quotes).  This is a PITA, and
-#   explains why there are so many levels of quotes.
-#
-# The locations
-#
-#   We use location.cc just like lalr1.cc, but because glr.c stores
-#   the locations in a union, the position and location classes
-#   must not have a constructor.  Therefore, contrary to lalr1.cc, we
-#   must not define "b4_location_constructors".  As a consequence the
-#   user must initialize the first positions (in particular the
-#   filename member).

-1.:     DJGPP specific changes.
-	=======================
-
-	The DJGPP port of Bison offers LFN and SFN support depending on which
-	OS it is running. If LFN support is available or not is determinated at
-	run time.  If LFN support is available (DOS session under Win9X, Win2K,
-	WinXP, etc.) the standard posix file name extensions will be used.
-	These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc.  If only SFN
-	support is available (plain DOS), then the standard MSDOS short file
-	names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
-	It should be noticed that this bison version needs the m4 program as
-	back end to generate the parser file (y.tab.c etc.) from the skeleton
-	files.  This implies that m4 must always be installed to get bison
-	working.  m4 will use a couple of m4 scripts that will be installed in
-	/dev/env/DJDIR/share/bison and shall not be removed.
-	It should also be noticed that the skeleton files bison.simple and
-	bison.hairy are no longer supported.  This applies also to the environ-
-	ment variables BISON_HAIRY and BISON_SIMPLE.  Those variables are *no*
-	longer honored at all.
-	The kind of skeleton file bison.hairy is no longer supported at all.
-	The skeleton file bison.simple is now called yacc.c and is an m4 script.
-	The other two skeleton files supported by this bison version are glr.c
-	and lalr1.cc.  The first one is a generalized LR C parser based on
-	Bison's LALR(1) tables and the second one is a experimental C++ parser
-	class.
-	As has been told before, bison uses m4 to generate the parser file.
-	This is done by forking and using pipes for the IPC.  MSDOS does not
-	support this functionality so this has been reproduced in the usual
-	way by redirecting stdin and stdout of bison and m4 to temporary files
-	and processing these files in sequence.
-	It should be noticed that due to the great amount of file names that do
-	not cleanly map to 8.3 file names, you will need an OS with LFN support
-	to configure and compile the sources. On Win98 this implies that the
-	generation of numeric tails for 8.3 file name aliases must be enabled
-	or the compilation will fail.
-
-
-	Please **read** the docs.
-
-
-2.:     Installing the binary package.
-	==============================
-
-2.1.:   Copy the binary distribution into the top DJGPP installation directory,
-	just unzip it preserving the directory structure running *ONE* of the
-	following commands:
-	  unzip32 bsn@[email protected]      or
-	  djtarx bsn@[email protected]       or
-	  pkunzip -d bsn@[email protected]
-
-
-
-3.:     Building the binaries from sources.
-	===================================
-
-3.1.:   Create a temporary directory and copy the source package into the
-	directory.  If you download the source distribution from one of the
-	DJGPP sites, just unzip it preserving the directory structure
-	running *ONE* of the following commands:
-	  unzip32 bsn@[email protected]      or
-	  djtarx bsn@[email protected]       or
-	  pkunzip -d bsn@[email protected]
-	and proceed to the paragraph 3.3, below.
-
-3.2.:   Source distributions downloaded from one of the GNU FTP sites need
-	some more work to unpack, if LFN support is not available.  If LFN is
-	available then you can extract the source files from the archive with
-	any unzip program and proceed to the paragraph 3.3, below.  Any file
-	name issue will be handled by the DJGPP configuration files.
-	To unpack the source distribution on SFN systems, first, you MUST use
-	the `djunpack' batch file to unzip the package.  That is because some
-	file names in the official distributions need to be changed to avoid
-	problems on the various platforms supported by DJGPP.
-	`djunpack' invokes the `djtar' program (that is part of the basic DJGPP
-	development kit) to rename these files on the fly given a file with
-	name mappings; the distribution includes a file `djgpp/fnchange.lst'
-	with the necessary mappings.  So you need first to retrieve that batch
-	file, and then invoke it to unpack the distribution.  Here's how:
-
-	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
-	  djunpack bison-@[email protected]
-
-	(The name of the distribution archive and the leading directory of the
-	path to `djunpack.bat' in the distribution will be different for
-	versions of Bison other than @VERSION@.)
-
-	If the argument to `djunpack.bat' include leading directories, it MUST
-	be given with the DOS-style backslashes; Unix-style forward slashes
-	will NOT work.
-
-	If the distribution comes as a .tar.bz2 archive, and your version of
-	`djtar' doesn't support bzip2 decompression, you need to unpack it as
-	follows:
-
-	  bnzip2 bison-@[email protected]
-	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
-	  djunpack bison-@[email protected]
-
-3.3.:   To build the binaries you will need the following binary packages:
-	  djdev203.zip (or a later but NOT a prior version)
-	  bsh204b.zip  (or a later but NOT a prior version)
-          gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
-          perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip,
-          sedNNNb.zip and m4NNN.zip
-
-	If you want to run the check you will need also:
-	  difNNNb.zip
-
-	NNN represents the latest version number of the binary packages. All
-	this packages can be found in the /v2gnu directory of any
-	ftp.delorie.com mirror.
-	You will need bsh204b.zip or later and *NOT* a prior version or
-	the build will fail.  The same applies to djdev203.zip.  Please note
-	that Bison requires m4-144b.zip or later to work properly.
-
-3.4.:   If for some reason you want to reconfigure the package cd into the top
-	srcdir (bison-@TREE_VERSION@) and run the following commands:
-	  del djgpp\config.cache
-	  make clean
-	  djgpp\config
-
-	Please note that you *MUST* delete the config.cache file in the djgpp
-	subdir or you will not really reconfigure the sources because the
-	configuration informations will be read from the cache file instead
-	of being newly computed.
-	To build the programs in a directory other than where the sources are,
-	you must add the parameter that specifies the source directory,
-	e.g:
-	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
-
-	Lets assume you want to build the binaries in a directory placed on a
-	different drive (z:\build in this case) from where the sources are,
-	then you will run the following commands:
-	  z:
-	  md \build
-	  cd \build
-	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
-
-	The order of the options and the srcdir option does not matter.  You
-	*MUST* use forward slashes to specify the source directory.
-
-	The batch file will set same environment variables, make MSDOS specific
-	modifications to the Makefile.in's and supply all other needed options
-	to the configure script.
-
-3.5.:   To compile the package run from the top srcdir the command:
-	  make
-
-3.6.:   Now you can run the tests if you like.  From the top srcdir run the
-	command:
-	  make check
-
-	No test should fail but the tests #131 (Doxygen Public Documentation)
-	and #132 (Doxygen Private Documentation) will be skipped.  Please note
-	that the testsuite only works with LFN available.  On plain DOS, most
-	of the tests will fail due to invalid DOS names.
-
-3.7.:   To install the binaries, header, library, catalogs, and info docs
-	run the following command from the top srcdir:
-	  make install
-
-	This will install the products into your DJGPP installation tree given
-	by the default prefix "/dev/env/DJDIR".  If you prefer to install them
-	into some other directory you will have to set prefix to the appropriate
-	value:
-	  make install prefix=z:/some/other/place
-
-
-
-	Send GNU bison specific bug reports to <[email protected]>.
-	Send suggestions and bug reports concerning the DJGPP port to
-	comp.os.msdos.djgpp or <[email protected]>.
-
-
-Enjoy.
