+			    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 Lesser 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

-  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.

+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
 
-  Each version is given a distinguishing version number.  If the
-Program specifies 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.

+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.

+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.

-	Avoid a minor race condition when `-m MODE' is specified, by using
-	open, fchown, and close rather than just chown.  To do that reliably --
-	even with an overly restrictive umask -- ensure that each mkdir,

-	approach (called the "more kosher" approach in the existing comments).
-	This makes "sort -R" quite a bit slower (about a factor of 2 on my

-	(usage): Tweak wording to mention STRING for --seed option.
-	(short_options): Rorder for consistency with other programs.
-	(rand_state): Now a struct, not a pointer to one.  All uses changed.
-	(HASH_WORDS, HASH_SIZE): Remove.
-	(get_hash): Remove comments around resbuf size, since we can assume C89.
-	Use a "more-kosher" (but slower) approach of invoking isaac_refill.
-	(keycompare): Adjust to the new get_hash.
-	Add a FIXME.
-	(badfieldspec): Omit recently-introduced comment; it isn't needed.
-	(main): Don't set need_random simply because gkey has it set; that
-	doesn't necessarily mean we'll need random numbers.
-	Redo seeding to match new get_hash approach.

-	* src/rand-isaac.c (isaac_mix): Declare to be static.

-
-	* src/sort.c (get_hash): Change position of `*' in parameter

-	(main): Split a long line so it fits in 80 columns.
-	(keycompare): Remove stray SPACE before TAB that was

-	* man/dirname.x: Cross-reference to basename and readlink.
-
-2005-12-05  Andreas Gruenbacher

-
-2005-12-03  Jim Meyering  <jim@meyering.net>
-
-	* src/rm.c (long_opts): Change the name of each undocumented, for-
-	testing-only option to start with `-', so that it cannot render
-	ambiguous any prefix it happens to share with some other option name.
-	Problem reported by Eric Blake.
-	* src/head.c (long_options): Likewise.
-	* src/tail.c (long_options): Likewise.
-
-	* tests/misc/head-elide-tail: Update uses of undocumented, for-
-	testing-only --presume* options to start with `---'.

-2005-11-30  Jim Meyering  <jim@meyering.net>
-
-	* Makefile.maint: Add a comment about cvsu.
-
-2005-11-25  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* NEWS: df updates for "none", "proc", inaccessible file systems.
-	* src/df.c (show_point): Ignore inaccessible file systems.
-	(usage): -a includes dummy file systems, not size-0 file systems.
-
-	* src/od.c (unsigned_long_long_int): Renamed from ulonglong_t,
-	to avoid collision with POSIX name space.  All uses changed.
-
-2005-11-24  Jim Meyering  <jim@meyering.net>
-
-	* tests/Makefile.am (EXTRA_DIST): Add acl to the list.
-	* tests/acl: Add `$0: ' prefix to diagnostics.
-
-	* .x-sc_require_config_h: Add lib/buffer-lcm.c to the list.
-
-2005-11-23  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* src/copy.c: Improve performance a bit by optimizing away
-	unnecessary system calls and going to a block size of at least
-	8192 (on normal hosts, anyway).  This improved performance 5% on my
-	Debian stable host (2.4.27 kernel, x86, copying from root
-	ext3 file system to itself).
-	Include "buffer-lcm.h".
-	(copy_reg): Omit last argument.  All callers changed.
-	Use xmalloc to allocate rather than trusting alloca
-	(which is unwise with large block sizes).
-	Declare locals more locally, if possible.
-	Use uintptr_t words instead of int words, for a bit more speed
-	when looking for null blocks on 64-bit hosts.
-	Optimize away reads of zero bytes on regular files.
-	In the typical case, insist on 8 KiB buffers, at least.
-	Avoid unnecessary extra call to fstat when checking for sparse files.
-	Avoid now-unnecessary cast to off_t, and "0L".
-	Avoid unnecessary test of *new_dst when checking for same owner
-	and group.
-
-2005-11-22  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* src/remove.c (rm): Don't assume C99 for-loop syntax.
-
-2005-11-22  Jim Meyering  <jim@meyering.net>
-
-	* src/remove.c (AD_push): Remove debugging cruft.
-
-	* tests/rm/unread2 (rm): Change expected diagnostic,
-	`cannot open directory' to `cannot remove', to align with
-	new version of rm.
-	* tests/rm/rm2: Ensure that rm now continues removing entries
-	even after certain types of failure.
-
-	* src/remove.c: Rewrite.  Now, this module is reentrant on systems
-	that provide openat (Solaris), and on systems like Linux+procfs
-	where our openat emulation code is reentrant.  This also fixes a
-	few low-probability leaks and eliminates some code that could,
-	in very unusual circumstances, cause rm() (via a callee) to exit.
-	* NEWS: Mention this.
-
-	* configure.ac: Put copyright dates all on one line so the
-	emacs function that updates them works properly.
-
-2005-11-18  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* configure.ac (AM_PROG_CC_C_O): Add.  Needed for CVS Automake.
-	Problem reported by Eric Blake.
-	(AC_PROG_CC_STDC): Use this instead of AC_PROG_CC, so that
-	we get a standard-conforming compiler.  This relies on the new
-	m4/c.m4 file.  Note that it's a bit tricky, since c.m4 doesn't
-	define AC_PROG_CC_STDC; we are relying on Autoconf 2.59 internals.
-	m4/c.m4 can go away with Autoconf 2.60 comes out.
-
-2005-11-17  Jim Meyering  <jim@meyering.net>
-
-	* src/remove.c (AD_mark_helper): Make a `char *' parameter `const'.
-	(AD_mark_current_as_unremovable): Likewise, but for a local.
-	(rm_1): Likewise.
-
-	* tests/mv/acl: Let traps handle removing temporary directories.
-
-	Expect acl-related tests to fail, until the corresponding
-	patches are committed.
-	* tests/mv/Makefile.am (XFAIL_TESTS): Add acl.
-	* tests/cp/Makefile.am (XFAIL_TESTS): Likewise.
-

-	* tests/mv/Makefile.am (TESTS): Add acl.
-	* tests/cp/Makefile.am (TESTS): Add acl.
-
-	* src/ls.c (basename_is_dot_or_dotdot): Correct wording in comment.
-
-2005-11-16  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* NEWS: Improve quality of ln's diagnostics.
-	* src/ln.c (do_link, usage): Likewise.
-	(do_link): Don't use alloca on a buffer of unbounded size.
-
-2005-11-16  Jim Meyering  <jim@meyering.net>
-
-	* tests/cp/fail-perm: Accommodate HPUX.  It appears to fail
-	with EACCES rather than EPERM.  Reported by Peter O'Gorman here:
-	http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/5766
-	This also affects AIX 4.3.3, according to Ralf Wildenhues, in
-	http://lists.gnu.org/archive/html/bug-coreutils/2006-05/msg00192.html
-
-2005-11-14  Jim Meyering  <jim@meyering.net>
-
-	* NEWS (sort): Mention consequences of today's mkstemp-safer.c fix.
-
-2005-11-13  Jim Meyering  <jim@meyering.net>
-
-	* announce-gen: Accept new option, --gpg-key-id=ID and
-	emit a blurb telling how to use the .sig files.
-	* Makefile.cfg (gpg_key_ID): Define.
-	* Makefile.maint (announcement): Use new option and key.

-	Require that most .c files include <config.h>.
-	* Makefile.maint (sc_require_config_h): New rule.
-	(syntax-check-rules): Add it.
-	* .x-sc_require_config_h: New file listing exceptions to the
-	above rule.  Some are legit, others are simply grandfathered in.
-	* Makefile.am (EXTRA_DIST): Add .x-sc_require_config_h here, too.
-
-2005-11-12  Jim Meyering  <jim@meyering.net>

-
-2005-11-08  Jim Meyering  <jim@meyering.net>

-2005-11-04  Paul Eggert  <eggert@cs.ucla.edu>
-
-	* src/ln.c: Include filenamecat.c.
-	(FILE_BASENAME_CONCAT): Remove.
-	(do_link): Remove last arg DEST_IS_DIR.  All callers changed.
-	(main): Use file_name_concat, base_name, and strip_trailing_slashes
-	instead of FILE_BASENAME_CONCAT.  This simplifies the code, and avoids
-	the use of alloca.
-
-2005-11-04  Jim Meyering  <jim@meyering.net>
-
-	* src/du.c (process_file): Don't overflow for files of size >= 2^31

-
-	* tests/dd/skip-seek: Fix typo in comment: s/fileutils/coreutils.
-	From Andreas Schwab.
-
-	* tests/dd/unblock-sync: Redirect stderr to /dev/null so the
-	`M+N records in/out' lines don't pollute `make check' output.
-
-	* tests/dd/skip-seek (sk-seek4): New test, to exercise the bug
-	fixed on 2005-10-31.  This test uses the new, IN_PIPE specifier.

-	the dircolors bug (NULL-dereference) fixed yesterday.
-
-2005-10-24  Jim Meyering  <jim@meyering.net>
-
-	* src/tac.c (tac_file): When determining whether a file is seekable,
-	also test whether it is a tty.  Using only the lseek-based test would
-	give a false positive on Solaris.  Reported by Peter Fales.
-
-2005-10-24  Dmitry V. Levin  <ldv@altlinux.org>

+	ls: Add support for SELinux and a slightly modified -Z option.
+	I started with the patches from Red Hat.
+	The entries below tell how the code evolved.
+
+	* src/ls.c (print_long_format, print_file_name_and_frills): When

+	with e.g. ENOTSUP), print it as "?", not "".

+	* src/ls.c: Remove the --lcontext and --scontext options.
+	Change the way -Z, --context work so that it no longer implies -l.
+	Thus, -Z -l will work like -lcontext and -Z without -l will work
+	like --scontext.
+
+	Adjust tests to reflect new 'ls -l' syntax -- affects only
+	systems with SELinux when operating on a file with no ACL.
+	These tests assumed that everything before the first space on
+	each line is the 10-byte mode string.  But there may also be a "+"
+	in the 11th column, just before the space.  However, note that this
+	is not new.  The same thing would have happened even without the
+	change below, when listing a file with an ACL.
+	* tests/chmod/equals, tests/cp/cp-parents, tests/cp/fail-perm:
+	* tests/cp/link-preserve, tests/install/basic-1, tests/misc/mknod:
+	* tests/mkdir/parents, tests/mkdir/special-1, tests/mv/partition-perm:
+
+	Don't make compilation depend on USE_ACL.  An SELinux security
+	context counts as an "alternate access control method", so ls
+	must output a "+" for each file with a security context.
+	* src/ls.c [struct fileinfo] (have_acl): Declare unconditionally.
+	(FILE_HAS_ACL): Remove macro definition.  Use f->have_acl directly.
+	(gobble_file): Record whether a file has a security context, and
+	update the condition used to determine whether to print the "+".
+	(gobble_file): Call getfilecon/lgetfilecon also when
+	format == long_format, so that we get the "+".
+
+	* src/ls.c (gobble_file): Add a comment explaining why (with a
+	security context option) ls doesn't exit nonzero due to e.g.,
+	getfilecon failing with errno == ENOTSUP.
+
+	* src/ls.c (gobble_file): Ignore failure of getfilecon if it's due
+	to ENOTSUP.
+
+	* src/ls.c (gobble_file): Factor out three small blocks using
+	getfilecon and lgetfilecon.
+	Don't ignore return value from getfilecon and lgetfilecon.
+
+	* src/ls.c (print_long_format): Don't use ?: (empty 2nd arg with C
+	ternary operator).
+	(print_scontext_format): Likewise.
+	(print_scontext): Declare to be "bool", not int.  Adjust uses.
+
+	* src/Makefile.am (dir_LDADD, ls_LDADD, vdir_LDADD): Add $(LIB_SELINUX).
+
+	* tests/misc/chcon: New file.
+	* tests/misc/chcon-fail: New file.

+	the configure-time --enable-selinux option.
+	* gl/modules/selinux-h: New module.
+	* bootstrap.conf (gnulib_modules): Add selinux-at.
+	* gl/lib/selinux-at.c, gl/lib/selinux-at.h: New files.
+	* gl/lib/se-selinux_.h: New file.

-Coreutils Contribution Guidelines
-
-
-Prerequisites
-=============
-You will need the "git" version control tools.
-On Fedora-based systems, do "yum install git".
-On Debian-based ones install the "git-core" package.
-Then run "git --version".  If that says it's older than
-version 1.4.4, then you'd do well to get a newer version.
-At worst, just download the latest stable release from
-http://git.or.cz/ and build from source.
-
-For details on building the programs in this package, see
-the file, README-hacking.
-
-
-Use the latest upstream sources
-===============================
-Base any changes you make on the latest upstream sources.
-You can get a copy of the latest with this command:
-
-    git clone git://git.sv.gnu.org/coreutils
-
-That downloads the entire repository, including revision control history
-dating back to 1991.  The repository (the part you download, and which
-resides in coreutils/.git) currently weighs in at about 30MB.  So you
-don't want to download it more often than necessary.  Once downloaded,
-you can get incremental updates by running one of these commands from
-inside your new coreutils/ directory:
-
-If you have made *no* changes:
-    git pull
-
-If you *have* made changes and mistakenly committed them to "master",
-do the following to put your changes on a private branch, "br", and
-to restore master to its unmodified (relative-to-upstream) state:
-    git checkout -b br
-    git checkout master
-    git reset --hard origin
-
-Then "git pull" should work.
-
-
-*Before* you commit changes
-===========================
-
-In this project, we much prefer patches that automatically record
-authorship.  That is important not just to give credit where due, but
-also from a legal standpoint (see below).  To create author-annotated
-patches with git, you must first tell git who you are.  That information
-is best recorded in your ~/.gitconfig file.  Edit that file, creating
-it if needed, and put your name and email address in place of these
-example values:
-
-[user]
-  name = Joe X. User
-  email = joe.user@example.com
-
-
-Your first commit: the quick and dirty way
-==========================================
-First of all, realize that to "commit" a change in git is a purely
-local operation.  It affects only the local repository (the .git/ dir)
-in your current coreutils/ hierarchy.
-
-To try this out, modify a file or two.  If you create a new file, you'll
-need to tell git about it with "git add new-file.c".  Commit all changes
-with "git commit -a".  That prompts you for a log message, which should
-include a one-line summary, a blank line, and ChangeLog-style entries
-for all affected files.  More on that below.
-
-Once your change is committed, you can create a proper patch that includes
-a log message and authorship information as well as any permissions
-changes.  Use this command to save that single, most-recent change set:
-
-  git format-patch --stdout -1 > DIFF
-
-The trouble with this approach is that you've just checked in a change
-(remember, it's only local) on the "master" branch, and that's where new
-changes would normally appear when you pull the latest from "upstream".
-When you "pull" from a remote repository to get the latest, your local
-changes on "master" may well induce conflicts.   For this reason, you
-may want to keep "master" free of any local changes, so that you can
-use it to track unadulterated upstream sources.
-
-However, if your cloned directory is for a one-shot patch submission and
-you're going to remove it right afterwards, then this approach is fine.
-Otherwise, for a more sustainable (and more generally useful, IMHO)
-process, read on about "topic" branches.
-
-
-Make your changes on a private "topic" branch
-=============================================
-So you checked out coreutils like this:
-
-  git clone git://git.sv.gnu.org/coreutils
-
-Now, cd into the coreutils/ directory and run:
-
-  git checkout -b my-topic
-
-That creates the my-topic branch and puts you on it.
-To see which branch you're on, type "git branch".
-Right after the clone, you were on "master" (aka the trunk).
-To get back to the trunk, do this:
-
-  git checkout master
-
-Note 1:
-    Be careful to run "git pull" only when on the "master" branch,
-    not when on a branch.  With newer versions of git, you can't cause
-    trouble if you forget, so this is a good reason to ensure you're
-    using 1.5.3.1 or newer.
-
-Note 2:
-    It's best not to try to switch from one branch to another if
-    you have pending (uncommitted) changes.  Sometimes it works,
-    sometimes the checkout will fail, telling you that your local
-    modifications conflict with changes required to switch branches.
-    However, in any case, you will *not* lose your uncommitted changes.
-
-Anyhow, get back onto your just-created branch:
-
-  git checkout my-topic
-
-Now, modify some file and commit it:
-
-  git commit some-file.c
-
-Personally, no matter what package I'm working on, I find it useful to
-put the ChangeLog entries *only* in the commit log, initially, unless
-I plan to commit/push right away.  Otherwise, I tend to get unnecessary
-merge conflicts with each rebase (see below).  In coreutils, I've gone
-a step further, and no longer maintain an explicit ChangeLog file in
-version control.  Instead, in a git working directory, you can view
-ChangeLog information via "git log".  However, each distribution tarball
-does include a ChangeLog file that is automatically generated from the
-git logs.
-
-So, you've committed a change.  But it's only in your local repository,
-and only on your "my-topic" branch.  Let's say you wait a day, and
-then see that someone else changed something and pushed it to the
-public repository.  Now, you want to update your trunk and "rebase"
-your changes on the branch so that they are once again relative to the
-tip of the trunk.  Currently, your branch is attached to the trunk at
-the next-to-last change set.
-
-First: update the trunk from the public repo:
-[you've first made sure that "git diff" produces no output]
-
-  git checkout master
-  git pull
-
-Now, return to your branch, and "rebase" relative to trunk (master):
-
-  git checkout my-topic
-  git rebase master
-
-If there are no conflicts, this requires no more work from you.
-However, let's say there was one in ChangeLog, since you didn't
-follow my advice and modified it anyway.
-git rebase will tell you there was a conflict and in which
-file, and instruct you to resolve it and then resume with
-"git rebase --continue" once that's done.
-
-So you resolve as usual, by editing ChangeLog (which has the
-usual conflict markers), then type "git rebase --continue".
-That will fail, with a diagnostic telling you to mark
-the file as "conflict resolved" by doing this:
-
-  git add ChangeLog
-
-Then, finally, you can proceed (possibly onto more conflict resolution,
-if there are conflicts in other files):
-
-  git rebase --continue
-
-Once it finishes, your changes on the branch are now relative to
-the tip of the trunk.
-
-Now use git format-patch, as above.
-
-
-Amending the most recent change on your private branch
-======================================================
-Let's say you've just committed a change on your private
-branch, and then realize that something about it is not right.
-It's easy to adjust:
-
-  edit your files # this can include running "git add NEW" or "git rm BAD"
-  git commit --amend -a
-  git format-patch --stdout -1 > your-branch.diff
-
-That replaces the most recent change-set with the revised one.
-
-
-
-Coreutils-specific:
-
-No more ChangeLog files
-=======================
-Do not modify any of the ChangeLog files in coreutils.  Starting in
-2008, the policy changed.  Before, we would insert the exact same text
-(or worse, sometimes slightly differing) into both the ChangeLog file
-and the commit log.  Now we put that information only in the commit log,
-and generate the top-level ChangeLog file from logs at "make dist" time.
-As such, there are strict requirements on the form of the commit log
-messages.
-
-
-Commit log requirements
-=======================
-Your commit log should always start with a one-line summary, the second
-line should be blank, and the remaining lines are usually ChangeLog-style
-entries for all affected files.  However, it's fine -- even recommended --
-to write a few lines of prose describing the change, when the summary
-and ChangeLog entries don't give enough of the big picture.  Omit the
-leading TABs that you're used to seeing in a "real" ChangeLog file, but
-keep the maximum line length at 72 or smaller, so that the generated
-ChangeLog lines, each with its leading TAB, will not exceed 80 columns.
-As for the ChangeLog-style content, please follow these guidelines:
-
-  http://www.gnu.org/software/guile/changelogs/guile-changelogs_3.html
-
-Try to make the summary line fit one of the following forms:
-
-  program_name: change-description
-  prog1, prog2: change-description
-  doc: change-description
-  tests: change-description
-  build: change-description
-  maint: change-description
-
-
-Curly braces: use judiciously
-=============================
-Omit the curly braces around an "if", "while", "for" etc. body only when
-that body occupies a single line.  In every other case we require the braces.
-This ensures that it is trivially easy to identify a single-*statement* loop:
-each has only one *line* in its body.
-
-Omitting braces with a single-line body is fine:
-
-     while (expr)
-       single_line_stmt ();
-
-However, the moment your loop/if/else body extends onto a second line,
-for whatever reason (even if it's just an added comment), then you should
-add braces.  Otherwise, it would be too easy to insert a statement just
-before that comment (without adding braces), thinking it is already a
-multi-statement loop:
-
-     while (true)
-       /* comment... */      // BAD: multi-line body without braces
-       single_line_stmt ();
-
-Do this instead:
-
-     while (true)
-       {  /* Always put braces around a multi-line body.  */
-         /* explanation... */
-         single_line_stmt ();
-       }
-
-There is one exception: when the second body line is not at the same
-indentation level as the first body line.
-
-     if (expr)
-       error (0, 0, _("a diagnostic that would make this line"
-                      " extend past the 80-column limit"));
-
-It is safe to omit the braces in the code above, since the
-further-indented second body line makes it obvious that this is still
-a single-statement body.
-
-To reiterate, don't do this:
-
-     if (expr)
-       while (expr_2)        // BAD: multi-line body without braces
-         {
-           ...
-         }
-
-Do this, instead:
-
-     if (expr)
-       {
-         while (expr_2)
-           {
-             ...
-           }
-       }
-
-However, there is one exception in the other direction, when even a
-one-line block should have braces.  That occurs when that one-line,
-brace-less block is an "else" block, and the corresponding "then" block
-*does* use braces.  In that case, either put braces around the "else"
-block, or negate the "if"-condition and swap the bodies, putting the
-one-line block first and making the longer, multi-line block be the
-"else" block.
-
-    if (expr)
-      {
-        ...
-        ...
-      }
-    else
-      x = y;    // BAD: braceless "else" with braced "then"
-
-This is preferred, especially when the multi-line body is more than a
-few lines long, because it is easier to read and grasp the semantics of
-an if-then-else block when the simpler block occurs first, rather than
-after the more involved block:
-
-    if (!expr)
-      x = y;                  /* more readable */
-    else
-      {
-        ...
-        ...
-      }
-
-If you'd rather not negate the condition, then add braces:
-
-    if (expr)
-      {
-        ...
-        ...
-      }
-    else
-      {
-        x = y;
-      }
-
-
-Use SPACE-only indentation in all[*] files
-==========================================
-We use space-only indentation in nearly all files.
-If you use Emacs and your coreutils working directory name matches,
-this code enables the right mode:
-
-  ;; In coreutils, indent with spaces everywhere (not TABs).
-  ;; Exceptions: Makefile and ChangeLog modes.
-  (add-hook 'find-file-hook '(lambda ()
-    (if (and buffer-file-name
-             (string-match "/coreutils\\>" (buffer-file-name))
-             (not (string-equal mode-name "Change Log"))
-             (not (string-equal mode-name "Makefile")))
-        (setq indent-tabs-mode nil))))
-
-[*] Makefile and ChangeLog files are exempt, of course.
-
-[FIXME: suggest vim syntax to do same thing, if it can be done safely.
- Most distros now "set nomodeline" by default for a good reason. ]
-
-
-Send patches to the address listed in --help output
-===================================================
-Please follow the guidelines in the "Sending your patches." section of
-git's own SubmittingPatches:
-
-  http://git.kernel.org/?p=git/git.git;a=blob;f=Documentation/SubmittingPatches
-
-
-Add documentation
-=================
-If you add a feature or change some user-visible aspect of a program,
-document it.  If you add an option, document it both in --help output
-(i.e., in the usage function that generates the --help output) and in
-doc/*.texi.  The man pages are generated from --help output, so
-you shouldn't need to change anything under man/.  User-visible changes
-are usually documented in NEWS, too.
-
-When writing prose (documentation, comments, log entries), use an
-active voice, not a passive one.  I.e., say "print the frobnozzle",
-not "the frobnozzle will be printed".
-
-Please add comments per the GNU Coding Standard:
-  http://www.gnu.org/prep/standards/html_node/Comments.html
-
-
-Minor syntactic preferences
-===========================
-[I hesitate to write this one down, because it appears to be an
- acquired taste, at least for native-English speakers.  It seems odd
- (if not truly backwards) to nearly anyone who doesn't have a strong
- mathematics background and perhaps a streak of something odd in their
- character ;-) ]
-In writing arithmetic comparisons, use "<" and "<=" rather than
-">" and ">=".  For some justification, read this:
-  http://thread.gmane.org/gmane.comp.version-control.git/3903/focus=4126
-
-const placement:
-Write "Type const *var", not "const Type *var".
-FIXME: dig up justification
-
-
-Be nice to translators
-======================
-Don't change translatable strings if you can avoid it.
-If you must rearrange individual lines (e.g., in multi-line --help
-strings), extract and create new strings, rather than extracting
-and moving into existing blocks.  This avoids making unnecessary
-work for translators.
-
-
-Add tests
-==========
-Nearly every significant change must be accompanied by a test suite
-addition that exercises it.  If you fix a bug, add at least one test that
-fails without the patch, but that succeeds once your patch is applied.
-If you add a feature, add tests to exercise as much of the new code
-as possible. Note to run tests/misc/new-test in isolation you can do:
-
-  (cd tests && make check TESTS=misc/new-test VERBOSE=yes)
-
-There are hundreds of tests in the tests/ directories.  You can use
-tests/sample-test as a template, or one of the various Perl-based ones
-in tests/misc.
-
-If writing tests is not your thing, don't worry too much about it,
-but do provide scenarios, input/output pairs, or whatever, along with
-examples of running the tool to demonstrate the new or changed feature,
-and someone else will massage that into a test (writing portable tests
-can be a challenge).
-
-
-Copyright assignment
-====================
-If your change is significant (i.e., if it adds more than ~10 lines),
-then you'll have to have a copyright assignment on file with the FSF.
-Since that involves first an email exchange between you and the FSF,
-and then the exchange (FSF to you, then back) of an actual sheet of paper
-with your signature on it, and finally, some administrative processing
-in Boston, the process can take a few weeks.
-
-The forms to choose from are in gnulib's doc/Copyright/ directory.
-If you want to assign a single change, you should use the file,
-doc/Copyright/request-assign.changes:
-
-    http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/Copyright/request-assign.changes;hb=HEAD
-
-If you would like to assign past and future contributions to a project,
-you'd use doc/Copyright/request-assign.future:
-
-    http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/Copyright/request-assign.future;hb=HEAD
-
-You may make assignments for up to four projects at a time.
-
-In case you're wondering why we bother with all of this, read this:
-
-    http://www.gnu.org/licenses/why-assign.html
-
-
-Run "make syntax-check", or even "make distcheck"
-================================================
-Making either of those targets runs many integrity and
-project-specific policy-conformance tests.  For example, the former
-ensures that you add no trailing blanks and no uses of certain deprecated
-functions.  The latter performs all "syntax-check" tests, and also
-ensures that the build completes with no warnings when using a certain
-set of gcc -W... options.  Don't even bother running "make distcheck"
-unless you have a reasonably up to date installation including recent
-versions of gcc and the linux kernel, and modern GNU tools.
-
-
-Ensure that your changes are indented properly.
-===============================================
-Format the code the way GNU indent does.
-In a file with the "indent-tabs-mode: nil" directive at the end,
-running "indent --no-tabs" should induce no change.
-With other files, there will be some existing differences.
-Try not to add any more.
-
-
-Avoid trailing white space
-==========================
-You may notice that the only trailing blanks in coreutils'
-version-controlled files are in a single directory: tests/pr,
-which contains expected output from various invocations of pr.
-
-Do not add any more trailing blanks anywhere.  While "make syntax-check"
-will alert you if you slip up, it's better to nip any problem in the
-bud, as you're typing.  A good way to help you adapt to this rule is
-to configure your editor to highlight any offending characters in the
-files you edit.  If you use Emacs, customize its font-lock mode (FIXME:
-provide more detail) or try one of its whitespace packages.  This appears
-to be the one that will end up in emacs 23:
-
-    http://www.emacswiki.org/emacs/WhiteSpace
-
-[that page says its version also works with emacs 21 and 22]
-If you use vim, add this to ~/.vimrc:
-
-    let c_space_errors=1
-    highlight RedundantSpaces ctermbg=red guibg=red
-    match RedundantSpaces /\s\+$\| \+\ze\t/
-
-
-Git can help too, by stopping you from committing any change that would
-add trailing blanks.  The example pre-commit hook contains code to check
-for trailing whitespace and spaces before tabs; enable it by moving it
-to the right place and making sure it is executable:
-
-    mv .git/hooks/pre-commit.sample .git/hooks/pre-commit
-
-With a repository created by git-1.5.6 or older, use this command:
-
-    chmod +x .git/hooks/pre-commit
-
-To manually check for whitespace errors before committing, you can use
-
-    git diff --check
-
-Git also has some settings to enable suitable internal whitespace checks.
-See the manpage for git-apply for details.
-

--------------------------------------------
-
-Miscellaneous useful git commands
-=================================
-
-  * gitk: give a graphical view of the revision graph of the current branch
-  * gitk --all: same, but display all branches
-  * git log: to get most of the same info in text form
-  * git log -p: same as above, but with diffs
-  * git log -p SOME_FILE: same as above, but limit to SOME_FILE
-  * git log -p -2 SOME_FILE: same as above, but print only two deltas
-  * git log -p -1: print the most recently committed change set
-  * git format-patch --stdout -1 > FILE: output the most recently committed
-      change set, in a format suitable to be submitted and/or applied via
-      "git am FILE".
-  * git reset --soft HEAD^: Commit the delta required to restore
-      state to the revision just before HEAD (i.e., next-to-last).
-  * git rebase -i master: run this from on a branch, and it gives
-      you an interface with which you can reorder and modify arbitrary
-      change sets on that branch.
-
-  * if you "misplace" a change set, i.e., via git reset --hard ..., so that
-    it's no longer reachable by any branch, you can use "git fsck" to find
-    its SHA1 and then tag it or cherry-pick it onto an existing branch.
-    For example, run this:
-      git fsck --lost-found HEAD && cd .git/lost-found/commit \
-        && for i in *; do git show $i|grep SOME_IDENTIFYING_STRING \
-        && echo $i; done
-    The "git fsck ..." command creates the .git/lost-found/... hierarchy
-    listing all unreachable objects.  Then the for loop
-    print SHA1s for commits that match via log or patch.
-    For example, say that found 556fbb57216b119155cdda824c98dc579b8121c8,
-    you could run "git show 556fbb57216b119" to examine the change set,
-    or "git checkout -b found 556fbb5721" to give it a branch name.
-    Finally, you might run "git checkout master && git cherry-pick 556fbb5721"
-    to put that change on the tip of "master".
-
--------------------------------------------
-
-Finding things to do
-====================
-If you don't know where to start, check out the TODO file for projects
-that look like they're at your skill-/interest-level.  Another good
-option is always to improve tests.  You never know what you might
-uncover when you improve test coverage, and even if you don't find
-any bugs your contribution is sure to be appreciated.
-
-A good way to quickly assess current test coverage is to use "lcov"
-to generate HTML coverage reports.  Follow these steps:
-
-  # configure with coverage information
-  ./configure CFLAGS="-g -fprofile-arcs -ftest-coverage"
-  make
-  # run whatever tests you want, i.e.:
-  make check
-  # run lcov
-  lcov -t coreutils -q -d lib -b lib -o lib.lcov -c
-  lcov -t coreutils -q -d src -b src -o src.lcov -c
-  # generate HTML from the output
-  genhtml -p `pwd` -t coreutils -q --output-directory lcov-html *.lcov
-
-Then just open the index.html file (in the generated lcov-html directory)
-in your favorite web browser.

 These notes intend to help people working on the checked-out sources.
 These requirements do not apply when building from a distribution tarball.
-See also HACKING for more detailed coreutils contribution guidelines.
 
 * Requirements
 
 We've opted to keep only the highest-level sources in the GIT repository.
 This eases our maintenance burden, (fewer merges etc.), but imposes more
 requirements on anyone wishing to build from the just-checked-out sources.
-Note the requirements to build the released archive are much less and
-are just the requirements of the standard ./configure && make procedure.
-Specific development tools and versions will be checked for and listed by
-the bootstrap script.  See README-prereq for specific notes on obtaining
-these prerequisite tools.
+For example, you have to use the latest stable versions of the maintainer
+tools we depend upon, including:
+
+- Automake <http://www.gnu.org/software/automake/>
+- Autoconf <http://www.gnu.org/software/autoconf/>
+- Bison <http://www.gnu.org/software/bison/>
+- Gettext <http://www.gnu.org/software/gettext/>
+- Gzip <http://www.gnu.org/software/gzip/>
+- Tar <http://www.gnu.org/software/tar/>
+- Wget <http://www.gnu.org/software/wget/>
+
+As of this writing, the latest stable version of Gzip is 1.2.4 but we
+suggest using test version 1.3.5 (or later, if one becomes available).
 
 Valgrind <http://valgrind.org/> is also highly recommended, if

+Only building the initial full source tree will be a bit painful.
+Later, a plain `git-pull && make' should be sufficient.
 
 * First GIT checkout
 
-You can get a copy of the source repository like this:
+Obviously, if you are reading these notes, you did manage to check out
+this package from GIT.  The next step is to get other files needed to
+build, which are extracted from other source packages:
 
-        $ git clone git://git.sv.gnu.org/coreutils
-        $ cd coreutils
-
-As an optional step, if you already have a copy of the gnulib git
-repository on your hard drive, then you can use it as a reference to
-reduce download time and disk space requirements:
-
-        $ export GNULIB_SRCDIR=/path/to/gnulib
-
-The next step is to get and check other files needed to build,
-which are extracted from other source packages:
-
-        $ ./bootstrap
-
-To use the most-recent gnulib (as opposed to the gnulib version that
-the package last synchronized to), do this next:
-
-        $ git submodule foreach git pull origin master
-        $ git commit -m 'build: update gnulib submodule to latest' gnulib
+	$ ./bootstrap
 
 And there you are!  Just
 
-        $ ./configure --quiet #[--enable-gcc-warnings] [*]
-        $ make
-        $ make check
+	$ ./configure
+	$ make
+	$ make check
 
 At this point, there should be no difference between your local copy,
 and the GIT master copy:
 
-        $ git diff
+	$ git-diff
 
 should output no difference.
 
 Enjoy!
 
-[*] The --enable-gcc-warnings option is useful only with glibc
-and with a very recent version of gcc.  You'll probably also have
-to use recent system headers.  If you configure with this option,
-and spot a problem, please be sure to send the report to the bug
-reporting address of this package, and not to that of gnulib, even
-if the problem seems to originate in a gnulib-provided file.
-
-* Submitting patches
-
-If you develop a fix or a new feature, please send it to the
-appropriate bug-reporting address as reported by the --help option of
-each program.  One way to do this is to use vc-dwim
-<http://www.gnu.org/software/vc-dwim/>), as follows.
-
-  Run the command "vc-dwim --help", copy its definition of the
-  "git-changelog-symlink-init" function into your shell, and then run
-  this function at the top-level directory of the package.
-
-  Edit the ChangeLog file that this command creates, creating a
-  properly-formatted entry according to the GNU coding standards
-  <http://www.gnu.org/prep/standards/html_node/Change-Logs.html>.
-
-  Run the command "vc-dwim" and make sure its output looks good.
-
-  Run "vc-dwim --commit".
-
-  Run the command "git format-patch --stdout -1", and email its output
-  in, using the output's subject line.

-Note please try to install/build official packages for your system.
-If these programs are not available use the following instructions
-to build them and install the results into a directory that you will
-then use when building this package.
-
-Even if the official version of a package for your system is too old,
-please install it, as it may be required to build the newer versions.
-The examples below install into $HOME/coreutils/deps/, so if you are
-going to follow these instructions, first ensure that your $PATH is
-set correctly by running this command:
-
-  prefix=$HOME/coreutils/deps
-  export PATH=$prefix/bin:$PATH
-
-* autoconf *
-
-  # Note Autoconf 2.62 or newer is needed to build automake-1.11.1
-  git clone --depth=1 git://git.sv.gnu.org/autoconf.git
-  git checkout v2.62
-  autoreconf -vi
-  ./configure --prefix=$prefix
-  make install
-
-* automake *
-
-  # Note help2man is required to build automake fully
-  git clone git://git.sv.gnu.org/automake.git
-  cd automake
-  git checkout v1.11.1
-  ./bootstrap
-  ./configure --prefix=$prefix
-  make install
-
-This package uses XZ utils (successor to LZMA) to create
-a compressed distribution tarball.  Using this feature of Automake
-requires version 1.10a or newer, as well as the xz program itself.
-
-* xz *
-
-  git clone git://ctrl.tukaani.org/xz.git
-  cd xz
-  ./autogen.sh
-  ./configure --prefix=$prefix
-  make install
-
-Now you can build this package as described in README-hacking.

README-release

@@ -1,107 +0,0 @@
-Here are most of the steps we (maintainers) follow when making a release.
-
-* start from a clean, up-to-date git directory.
-
-    git checkout master; git pull
-
-* Run ./configure && make maintainer-clean
-
-* Ensure that the desired versions of autoconf, automake, bison, etc.
-  are in your PATH.  See the buildreq list in bootstrap.conf for
-  the complete list.
-
-* Ensure that you're on "master" with no uncommitted diffs.
-  This should produce no output: git checkout master; git diff
-
-* Ensure that you've pushed all changes that belong in the release
-  and that the NixOS/Hydra autobuilder is reporting all is well:
-
-      http://hydra.nixos.org/jobset/gnu/coreutils-master
-
-* Run bootstrap one last time.  This downloads any new translations:
-
-    ./bootstrap
-
-FIXME: enable excluded programs like arch? to get their manual pages?
-
-* Pre-release testing:
-
-  Run the following on at least one SELinux-enabled (enforcing) and
-  one non-SELinux system:
-
-    make distcheck
-    make -j1 check RUN_VERY_EXPENSIVE_TESTS=yes RUN_EXPENSIVE_TESTS=yes
-    sudo env PATH="$PATH" NON_ROOT_USERNAME=$USER make -k check-root
-
-  Note the -j1 above.  If you use -jN, for larger N, some of the expensive
-  tests are likely to interfere with concurrent performance-measuring or
-  timing-sensitive tests, resulting in spurious failures.
-
-  If "make distcheck" doesn't run "make syntax-check" for you, then run
-  it manually:
-
-    make syntax-check
-
-* Set the date, version number, and release type [stable/alpha/beta] on
-  line 3 of NEWS, commit that, and tag the release by running e.g.,
-
-    build-aux/do-release-commit-and-tag X.Y stable
-
-* Run the following to create release tarballs.  Your choice selects the
-  corresponding upload-to destination in the emitted gnupload command.
-  The different destinations are specified in cfg.mk.  See the definitions
-  of gnu_ftp_host-{alpha,beta,stable}.
-
-    # "TYPE" must be stable, beta or alpha
-    make TYPE
-
-* Test the tarball.  copy it to a few odd-ball systems and ensure that
-  it builds and passes all tests.
-
-* While that's happening, write the release announcement that you will
-  soon post.  Start with the template, $HOME/announce-coreutils-X.Y
-  that was just created by that "make" command.
-
-Once all the builds and tests have passed,
-
-* Run the gnupload command that was suggested by your "make stable" run above.
-
-* Wait a few minutes (maybe up to 30?) and then use the release URLs to
-  download all tarball/signature pairs and use gpg --verify to ensure
-  that they're all valid.
-
-* Push the NEWS-updating changes and the new tag:
-
-    v=$(cat .prev-version)
-    git push origin master tag v$v
-
-* Announce it on Savannah first, so you can include the preferable
-  savannah.org announcement link in the email message.
-
-  From here:
-    https://savannah.gnu.org/projects/coreutils/
-  click on the "submit news", then write something like the following:
-  (If there is no such button, then enable "News" for the project via
-   the Main -> "Select Features" menu item, or via this link:
-   https://savannah.gnu.org/project/admin/editgroupfeatures.php?group=coreutils)
-
-    Subject: coreutils-X.Y released [stable]
-    +verbatim+
-    ...paste the announcement here...
-    -verbatim-
-
-  Then go here to approve it:
-    https://savannah.gnu.org/news/approve.php?group=coreutils
-
-* Send the announcement email message.
-
-* Approve the announcement here:
-  http://lists.gnu.org/mailman/admindb/coreutils-announce
-
-* After each non-alpha release, update the on-line manual accessible via
-
-    http://www.gnu.org/software/coreutils/manual/
-
-  by running this:
-
-    build-aux/gnu-web-doc-update

   dd: consider adding an option to suppress `bytes/block read/written'

-remove `%s' notation (now that they're all gone, add a maint.mk sc_
-    rule to ensure no new ones are added):
-  grep -E "\`%.{,4}s'" src/*.c
+Implement Ulrich Drepper's suggestion to use getgrouplist rather
+  than getugroups.  This affects only `id', but makes a big difference
+  on systems with many users and/or groups, and makes id usable once
+  again on systems where access restrictions make getugroups fail.
+  But first we'll need a run-test (either in an autoconf macro or at
+  run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
+  In that case, we'd revert to using a new (to-be-written) getgrouplist
+  module that does most of what `id' already does.  Or just avoid the
+  buggy use of getgrouplist by never passing it a buffer of length zero.
+  See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200327
 
-remove all uses of the `register' keyword: Done.  add a maint.mk rule
-  for this, too.
+remove `%s' notation:
+  grep -E "\`%.{,4}s'" src/*.c
 
 remove or adjust chown's --changes option, since it
   can't always do what it currently says it does.
 
-Support arbitrary-precision arithmetic in those tools for which it
-makes sense.  Factor and expr already support this via libgmp.
-The "test" program is covered via its string-based comparison of
-integers.  To be converted: seq.
-
 Adapt tools like wc, tr, fmt, etc. (most of the textutils) to be
   multibyte aware.  The problem is that I want to avoid duplicating
   significant blocks of logic, yet I also want to incur only minimal
   (preferably `no') cost when operating in single-byte mode.
 
+Remove all uses of the `register' keyword
+
 pr's use of nstrftime can make it malloc a very large (up to SIZE_MAX) buffer
 
+ls.c: use gettime rather than clock_gettime, gettimeofday, time
