@@ -21,6 +21,7 @@ These correctness fixes landed after the 2026-10-03 checkpoint below:
 - The footer keeps its status readable at 100–160 columns by dropping optional view hints first. The header label no longer runs into the file count, condensed help keeps its indentation, and the small-terminal notice wraps.
 - The footer source status describes the cursor's file instead of any file visible on screen.
 - Host calls into the syntax worker recover a poisoned mailbox lock instead of panicking; a dead worker surfaces through the existing `Engine::poll` error.
+- The vendored, patched `libgit2-sys` is gone; the build uses the published crate with its bundled libgit2. Stock libgit2 cuts unquoted `rename`/`copy` names at whitespace, so the parser now receives those names in Git's quoted form and line offsets map back to the supplied bytes. `LIBGIT2_NO_VENDOR` is still rejected at build time.
 - Unnamed temporary files (patch spool, Git helper output, clipboard input) are created owner-only. On Linux they previously took the umask-derived mode, usually 0644. Linux CI found this.
 
 Canonical source output is byte-identical to the 2026-10-03 build for the five DiffsHub corpus patches and the repository fixtures.

-
-### Changed
-
-- Updated to libgit2 [1.9.3](https://github.com/libgit2/libgit2/releases/tag/v1.9.3)
-  [#1242](https://github.com/rust-lang/git2-rs/pull/1242)
-
-### Fixed
-
-- Fixed the signature of `git_config_backend::unlock`.
-  Previously the second `c_int` argument was missing
-  and the declaration was unusable.
-  [#1181](https://github.com/rust-lang/git2-rs/pull/1181)
-
-### Added
-
-- Added experimental SHA256 OID support behind a new `unstable-sha256` Cargo feature.
-  This reflects upstream libgit2's `GIT_EXPERIMENTAL_SHA256` feature gate,
-  and requires the linked libgit2 C library to be built with the experimental flag.
-  When enabled, the build supports linking against a system `libgit2-experimental.so`.
-  See the feature description in `Cargo.toml` for ABI-stability caveats.
-  [#1201](https://github.com/rust-lang/git2-rs/pull/1201)
-- Added binding for `git_repository_oid_type`.
-  [#1204](https://github.com/rust-lang/git2-rs/pull/1204)
-- Added binding for `git_oid_is_zero`, replacing the deprecated `git_oid_iszero`.
-  [#1205](https://github.com/rust-lang/git2-rs/pull/1205)
-- Added binding for `git_remote_oid_type`.
-  [#1242](https://github.com/rust-lang/git2-rs/pull/1242)
-- Added `GIT_REPOSITORY_INIT_RELATIVE_GITLINK` flag.
-  [#1242](https://github.com/rust-lang/git2-rs/pull/1242)
-- Added bindings for the `git_merge_file_input` API, including `git_merge_file_input_init`.
-  [#1210](https://github.com/rust-lang/git2-rs/pull/1210)
-- Added bindings for `git_odb_stream` and `git_odb_stream_t`.
-  [#1181](https://github.com/rust-lang/git2-rs/pull/1181)
-- Added bindings for `git_reference_iterator`.
-  [#1181](https://github.com/rust-lang/git2-rs/pull/1181)
-- Added bindings for APIs from `git2/sys/config.h`,
-  including the missing `iterator` function on `git_config_backend`.
-  [#1181](https://github.com/rust-lang/git2-rs/pull/1181)
-- Added binding for `git_reference_dup`.
-  [#1233](https://github.com/rust-lang/git2-rs/pull/1233)
-- Added binding for `git_signature_default_from_env`.
-  [#1237](https://github.com/rust-lang/git2-rs/pull/1237)
-
-## 0.18.3+1.9.2 - 2025-12-06
-[0.18.2...0.18.3](https://github.com/rust-lang/git2-rs/compare/libgit2-sys-0.18.2+1.9.1...libgit2-sys-0.18.3+1.9.2)
-
-### Changed
-- Updated to libgit2 [1.9.2](https://github.com/libgit2/libgit2/releases/tag/v1.9.2)
-  [#1195](https://github.com/rust-lang/git2-rs/pull/1195)
-
-  Note that this release fixes two security issues. However, the Rust bindings do not provide direct support for the affected APIs. In particular:
-  - The `libgit2-sys` crate does not support building the vendored C library with the `GIT_SSH_EXEC` setting. This will only be an issue if you are binding to a system-provided library built with this setting.
-  - The `git2` crate does not support custom SSH credentials. However, the `libgit2-sys` crate does export the `git_cred_ssh_custom_new` C-binding. Any projects using the C bindings directly are affected.

-# Local parser correction
-
-Base: the published `libgit2-sys` crate `0.18.8+1.9.7`, containing libgit2 1.9.7.
-The original crate SHA-256 is
-`7f7c568b25d7489bc3fb2988ed69ab111d2944d2f5fec3d5c987fe545ea97b50`.
-Its VCS record identifies git2-rs commit
-`6c93812dbc1c34aef6e6464a645545b4a4299807`.
-
-The complete published crate remains present. Only `build.rs` and
-`libgit2/src/libgit2/patch_parse.c` differ from that crate, apart from this note.
-
-## Behavior
-
-Git rename and copy headers contain an unprefixed filename. Unquoted filenames
-can contain leading, interior, and trailing spaces. The parser consumes these
-names through the line ending without trimming filename whitespace.
-Quoted names retain the existing token boundary and escape decoder. Extra data
-after a quoted name remains an error. The temporary path buffer is released
-on decoding failure.
-
-The common path helper retains its previous trimming behavior for other headers.
-No patch bytes, source offsets, source records, or application rendering rules
-change. The application enables `vendored-libgit2`. The build rejects a nonzero
-`LIBGIT2_NO_VENDOR` override to prevent an unpatched system library from bypassing
-the correction.
-
-The regression contracts generate real Git rename and copy patches. They check
-exact safe-display names, status, supplied source bytes, line numbers, newline
-markers, retained source export, both terminal layouts, and file navigation.
-Malformed quoted names remain errors.
-
-## Source and notices
-
-- [Published crate](https://crates.io/crates/libgit2-sys/0.18.8+1.9.7)
-- [Git patch format](https://git-scm.com/docs/diff-format)
-- Bindings: `LICENSE-MIT` and `LICENSE-APACHE`, unchanged.
-- libgit2: `libgit2/COPYING`, including its linking exception, unchanged.
-- Bundled component notices remain in their original directories.
-
-The changed C file carries a dated modification notice. This local correction
-does not change the license of the original components.

-			LINKING EXCEPTION
-
- In addition to the permissions in the GNU General Public License,
- the authors give you unlimited permission to link the compiled
- version of this library into combinations with other programs,
- and to distribute those combinations without any restriction
- coming from the use of this file.  (The General Public License
- restrictions do apply in other respects; for example, they cover
- modification of the file, and distribution when not linked into

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  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
-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 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 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.
-
-  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.
-
-  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.
-
-  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.
-
-		    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.
-
-  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
-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.
-
-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.
-
-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.
-
-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.
-
-  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 a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-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.
-
-  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.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-                       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-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 this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-                  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, 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 library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete 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 distribute a copy of this License along with the
-Library.
-
-  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 Library or any portion
-of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-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 Library, 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 Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you 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.
-
-  If distribution of 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 satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be 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.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library 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.
-
-  9. 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 Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-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 with
-this License.
-
-  11. 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
-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 Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library 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 Library.
-
-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.
-
-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.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library 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.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser 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 Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-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.
-
-                            NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

-`libgit2` is a portable, pure C implementation of the Git core methods
-provided as a linkable library with a solid API, allowing to build Git
-functionality into your application.
-
-`libgit2` is used in a variety of places, from GUI clients to hosting
-providers ("forges") and countless utilities and applications in
-between. Because it's written in C, it can be made available to any
-other programming language through "bindings", so you can use it in
-[Ruby](https://github.com/libgit2/rugged),
-[.NET](https://github.com/libgit2/libgit2sharp),
-[Python](http://www.pygit2.org/),
-[Node.js](http://nodegit.org),
-[Rust](https://github.com/rust-lang/git2-rs), and more.
-
-`libgit2` is licensed under a **very permissive license** (GPLv2 with
-a special Linking Exception). This means that you can link against
-the library with any kind of software without making that software
-fall under the GPL. Changes to libgit2 would still be covered under
-its GPL license.

-Using libgit2
-=============
-
-Most of these instructions assume that you're writing an application
-in C and want to use libgit2 directly.  If you're _not_ using C,
-and you're writing in a different language or platform like .NET,
-Node.js, or Ruby, then there is probably a
-"[language binding](#language-bindings)" that you can use to take care
-of the messy tasks of calling into native code.
-
-But if you _do_ want to use libgit2 directly - because you're building
-an application in C - then you may be able use an existing binary.
-There are packages for the
-[vcpkg](https://github.com/Microsoft/vcpkg) and
-[conan](https://conan.io/center/recipes/libgit2)
-package managers.  And libgit2 is available in 
-[Homebrew](https://formulae.brew.sh/formula/libgit2) and most Linux
-distributions.
-
-However, these versions _may_ be outdated and we recommend using the
-latest version if possible.  Thankfully libgit2 is not hard to compile.
-
-Quick Start
-===========
-
-**Prerequisites** for building libgit2:
-
-1. [CMake](https://cmake.org/), and is recommended to be installed into
-   your `PATH`.
-2. [Python](https://www.python.org) is used by our test framework, and
-   should be installed into your `PATH`.
-3. C compiler: libgit2 is C90 and should compile on most compilers.
-   * Windows: Visual Studio is recommended
-   * Mac: Xcode is recommended
-   * Unix: gcc or clang is recommended.
-
-**Build**
-
-1. Create a build directory beneath the libgit2 source directory,
-   and change into it: `mkdir build && cd build`
-2. Create the cmake build environment: `cmake ..`
-3. Build libgit2: `cmake --build .`
-
-Trouble with these steps?  Read our [troubleshooting guide](docs/troubleshooting.md).
-More detailed build guidance is available below.
-
-Getting Help
-============
-
-**Chat with us**
-
-- via IRC: join [#libgit2](https://web.libera.chat/#libgit2) on
-  [libera](https://libera.chat).
-- via Slack: visit [slack.libgit2.org](http://slack.libgit2.org/)
-  to sign up, then join us in `#libgit2`
-
-**Getting Help**
-
-If you have questions about the library, please be sure to check out the
-[API documentation](https://libgit2.org/libgit2/).  If you still have
-questions, reach out to us on Slack or post a question on 
-[StackOverflow](http://stackoverflow.com/questions/tagged/libgit2)
-(with the `libgit2` tag).
-
-**Reporting Bugs**
-
-Please open a [GitHub Issue](https://github.com/libgit2/libgit2/issues)
-and include as much information as possible.  If possible, provide
-sample code that illustrates the problem you're seeing.  If you're
-seeing a bug only on a specific repository, please provide a link to
-it if possible.
-
-We ask that you not open a GitHub Issue for help, only for bug reports.
-
-**Reporting Security Issues**
-
-Please have a look at SECURITY.md.
-
-What It Can Do
-==============
-
-libgit2 provides you with the ability to manage Git repositories in the
-programming language of your choice.  It's used in production to power many
-applications including GitHub.com, Plastic SCM and Azure DevOps.
-
-It does not aim to replace the git tool or its user-facing commands. Some
-APIs resemble the plumbing commands as those align closely with the
-concepts of the Git system, but most commands a user would type are out
-of scope for this library to implement directly.
-
-The library provides:
-
-* SHA conversions, formatting and shortening
-* abstracted ODB backend system
-* commit, tag, tree and blob parsing, editing, and write-back
-* tree traversal
-* revision walking
-* index file (staging area) manipulation
-* reference management (including packed references)
-* config file management
-* high level repository management
-* thread safety and reentrancy
-* descriptive and detailed error messages
-* ...and more (over 175 different API calls)
-
-As libgit2 is purely a consumer of the Git system, we have to
-adjust to changes made upstream. This has two major consequences:
-
-* Some changes may require us to change provided interfaces. While
-  we try to implement functions in a generic way so that no future
-  changes are required, we cannot promise a completely stable API.
-* As we have to keep up with changes in behavior made upstream, we
-  may lag behind in some areas. We usually to document these
-  incompatibilities in our issue tracker with the label "git change".
-
-Optional dependencies
-=====================
-
-While the library provides git functionality with very few
-dependencies, some recommended dependencies are used for performance
-or complete functionality.
-
-- Hash generation: Git uses SHA1DC (collision detecting SHA1) for
-  its default hash generation. SHA256 support is experimental, and
-  optimized support is provided by system libraries on macOS and
-  Windows, or by the HTTPS library on Unix systems when available.
-- Threading: is provided by the system libraries on Windows, and
-  pthreads on Unix systems.
-- HTTPS: is provided by the system libraries on macOS and Windows,
-  or by OpenSSL or mbedTLS on other Unix systems.
-- SSH: is provided by [libssh2](https://libssh2.org/) or by invoking
-  [OpenSSH](https://www.openssh.com).
-- Unicode: is provided by the system libraries on Windows and macOS.
-
-Initialization
-===============
-
-The library needs to keep track of some global state. Call
-
-    git_libgit2_init();
-
-before calling any other libgit2 functions. You can call this function many times. A matching number of calls to
-
-    git_libgit2_shutdown();
-
-will free the resources.  Note that if you have worker threads, you should
-call `git_libgit2_shutdown` *after* those threads have exited.  If you
-require assistance coordinating this, simply have the worker threads call
-`git_libgit2_init` at startup and `git_libgit2_shutdown` at shutdown.
-
-Threading
-=========
-
-See [threading](docs/threading.md) for information
-
-Conventions

-
-See [conventions](docs/conventions.md) for an overview of the external
-and internal API/coding conventions we use.
-
-Building libgit2 - Using CMake
-==============================
-
-Building
---------
-
-`libgit2` builds cleanly on most platforms without any external
-dependencies as a requirement. `libgit2` is built using
-[CMake](<https://cmake.org/>) (version 2.8 or newer) on all platforms.
-
-On most systems you can build the library using the following commands
-
-	$ mkdir build && cd build
-	$ cmake ..
-	$ cmake --build .
-
-To include the examples in the build, use `cmake -DBUILD_EXAMPLES=ON ..`
-instead of `cmake ..`. The built executable for the examples can then
-be found in `build/examples`, relative to the toplevel directory.
-
-Alternatively you can point the CMake GUI tool to the CMakeLists.txt file and generate platform specific build project or IDE workspace.
-
-If you're not familiar with CMake, [a more detailed explanation](https://preshing.com/20170511/how-to-build-a-cmake-based-project/) may be helpful.
-
-Advanced Options
-----------------
-
-You can specify a number of options to `cmake` that will change the
-way `libgit2` is built. To use this, specify `-Doption=value` during
-the initial `cmake` configuration. For example, to enable SHA256
-compatibility:
-
-	$ mkdir build && cd build
-	$ cmake -DEXPERIMENTAL_SHA256=ON ..
-	$ cmake --build .
-
-libgit2 options:
-
-* `EXPERIMENTAL_SHA256=ON`: turns on SHA256 compatibility; note that
-  this is an API-incompatible change, hence why it is labeled
-  "experimental"
-
-Build options:
-
-* `BUILD_EXAMPLES=ON`: builds the suite of example code
-* `BUILD_FUZZERS=ON`: builds the fuzzing suite
-* `ENABLE_WERROR=ON`: build with `-Werror` or the equivalent, which turns
-  compiler warnings into errors in the libgit2 codebase (but not its
-  dependencies)
-
-Dependency options:
-
-* `USE_SSH=type`: enables SSH support and optionally selects the provider;
-  `type` can be set to `libssh2` or `exec` (which will execute an external
-  OpenSSH command). `ON` implies `libssh2`; defaults to `OFF`.
-* `USE_HTTPS=type`: enables HTTPS support and optionally selects the
-  provider; `type` can be set to `OpenSSL`, `OpenSSL-Dynamic` (to not
-  link against OpenSSL, but load it dynamically), `SecureTransport`,
-  `Schannel` or `WinHTTP`; the default is `SecureTransport` on macOS,
-  `WinHTTP` on Windows, and whichever of `OpenSSL` or `mbedTLS` is
-  detected on other platforms. Defaults to `ON`.
-* `USE_SHA1=type`: selects the SHA1 mechanism to use; `type` can be set
-  to `CollisionDetection`, `HTTPS` to use the system or HTTPS provider,
-  or one of `OpenSSL`, `OpenSSL-Dynamic`, `OpenSSL-FIPS` (to use FIPS
-  compliant routines in OpenSSL), `CommonCrypto`, or `Schannel`.
-  Defaults to `CollisionDetection`. This option is retained for
-  backward compatibility and should not be changed.
-* `USE_SHA256=type`: selects the SHA256 mechanism to use; `type` can be
-  set to `HTTPS` to use the system or HTTPS driver, `builtin`, or one of
-  `OpenSSL`, `OpenSSL-Dynamic`, `OpenSSL-FIPS` (to use FIPS compliant
-  routines in OpenSSL), `CommonCrypto`, or `Schannel`. Defaults to `HTTPS`.
-* `USE_GSSAPI=<on/off>`: enables GSSAPI for SPNEGO authentication on
-  Unix. Defaults to `OFF`.
-* `USE_HTTP_PARSER=type`: selects the HTTP Parser; either `http-parser`
-  for an external
-  [`http-parser`](https://github.com/nodejs/http-parser) dependency,
-  `llhttp` for an external [`llhttp`](https://github.com/nodejs/llhttp)
-  dependency, or `builtin`. Defaults to `builtin`.
-* `REGEX_BACKEND=type`: selects the regular expression backend to use;
-  one of `regcomp_l`, `pcre2`, `pcre`, `regcomp`, or `builtin`. The
-  default is to use `regcomp_l` where available, PCRE if found, otherwise,
-  to use the builtin.
-* `USE_BUNDLED_ZLIB=type`: selects the bundled zlib; either `ON` or `OFF`.
-  Defaults to using the system zlib if available, falling back to the
-  bundled zlib.
-
-Locating Dependencies
----------------------
-
-The `libgit2` project uses `cmake` since it helps with cross-platform
-projects, especially those with many dependencies. If your dependencies
-are in non-standard places, you may want to use the `_ROOT_DIR` options
-to specify their location. For example, to specify an OpenSSL location:
-
-	$ cmake -DOPENSSL_ROOT_DIR=/tmp/openssl-3.3.2 ..
-
-Since these options are general to CMake, their
-[documentation](https://cmake.org/documentation/) may be helpful. If
-you have questions about dependencies, please [contact us](#getting-help).
-
-Running Tests
--------------
-
-Once built, you can run the tests from the `build` directory with the command
-
-	$ ctest -V
-
-Alternatively you can run the test suite directly using,
-
-	$ ./libgit2_tests
-
-Invoking the test suite directly is useful because it allows you to execute
-individual tests, or groups of tests using the `-s` flag.  For example, to
-run the index tests:
-
-	$ ./libgit2_tests -sindex
-
-To run a single test named `index::racy::diff`, which corresponds to
-the test function
-[`test_index_racy__diff`](https://github.com/libgit2/libgit2/blob/main/tests/libgit2/index/racy.c#L22):
-
-	$ ./libgit2_tests -sindex::racy::diff
-
-The test suite will print a `.` for every passing test, and an `F` for any
-failing test.  An `S` indicates that a test was skipped because it is not
-applicable to your platform or is particularly expensive.
-
-**Note:** There should be _no_ failing tests when you build an unmodified
-source tree from a [release](https://github.com/libgit2/libgit2/releases),
-or from the [main branch](https://github.com/libgit2/libgit2/tree/main).
-Please contact us or
-[open an issue](https://github.com/libgit2/libgit2/issues)
-if you see test failures.
-
-Installation
-------------
-
-To install the library you can specify the install prefix by setting:
-
-	$ cmake .. -DCMAKE_INSTALL_PREFIX=/install/prefix
-	$ cmake --build . --target install
-
-Advanced Usage
---------------
-
-For more advanced use or questions about CMake please read the
-[CMake FAQ](https://cmake.org/Wiki/CMake_FAQ).
-
-The following CMake variables are declared:
-
-- `CMAKE_INSTALL_BINDIR`: Where to install binaries to.
-- `CMAKE_INSTALL_LIBDIR`: Where to install libraries to.
-- `CMAKE_INSTALL_INCLUDEDIR`: Where to install headers to.
-- `BUILD_SHARED_LIBS`: Build libgit2 as a Shared Library (defaults to ON)
-- `BUILD_TESTS`: Build the unit and integration test suites (defaults to ON)
-- `USE_THREADS`: Build libgit2 with threading support (defaults to ON)
-
-To list all build options and their current value, you can do the
-following:
-
-	# Create and set up a build directory
-	$ mkdir build && cd build
-	$ cmake ..
-
-	# List all build options and their values
-	$ cmake -L
-
-Compiler and linker options
----------------------------
-
-There are several options that control the behavior of the compiler and
-linker. These flags may be useful for cross-compilation or specialized
-setups.
-
-- `CMAKE_C_FLAGS`: Set your own compiler flags
-- `CMAKE_C_STANDARD`: the C standard to compile against; defaults to `C90`
-- `CMAKE_C_EXTENSIONS`: whether compiler extensions are supported; defaults to `OFF`
-- `CMAKE_FIND_ROOT_PATH`: Override the search path for libraries
-- `ZLIB_LIBRARY`, `OPENSSL_SSL_LIBRARY` AND `OPENSSL_CRYPTO_LIBRARY`:
-Tell CMake where to find those specific libraries
-- `LINK_WITH_STATIC_LIBRARIES`: Link only with static versions of
-system libraries
-
-macOS
--------
-
-If you'd like to work with Xcode, you can generate an Xcode project with "-G Xcode".
-
-	# Create and set up a build directory
-	$ mkdir build && cd build
-	$ cmake -G Xcode ..
-
-> [!TIP]
-> Universal binary support:
-> 
-> If you want to build a universal binary for macOS 11.0+, CMake sets it
-> all up for you if you use `-DCMAKE_OSX_ARCHITECTURES="x86_64;arm64"`
-> when configuring.
-> 
-> [Deprecated] If you want to build a universal binary for Mac OS X
-> (10.4.4 ~ 10.6), CMake sets it all up for you if you use
-> `-DCMAKE_OSX_ARCHITECTURES="i386;x86_64"` when configuring.
-
-iOS
--------
-
-1. Get an iOS cmake toolchain File:
-
-You can use a pre-existing toolchain file like [ios-cmake](https://github.com/leetal/ios-cmake) or write your own.
-
-2. Specify the toolchain and system Name:
-
-- The CMAKE_TOOLCHAIN_FILE variable points to the toolchain file for iOS.
-- The CMAKE_SYSTEM_NAME should be set to iOS.
-
-3. Example Command:
-
-Assuming you're using the ios-cmake toolchain, the command might look like this:
-
-```
-cmake -G Xcode -DCMAKE_TOOLCHAIN_FILE=path/to/ios.toolchain.cmake -DCMAKE_SYSTEM_NAME=iOS -DPLATFORM=OS64 ..
-```
-
-4. Build the Project:
-
-After generating the project, open the .xcodeproj file in Xcode, select your iOS device or simulator as the target, and build your project.
-
-Android
--------
-
-Extract toolchain from NDK using, `make-standalone-toolchain.sh` script.
-Optionally, crosscompile and install OpenSSL inside of it. Then create CMake
-toolchain file that configures paths to your crosscompiler (substitute `{PATH}`
-with full path to the toolchain):
-
-	SET(CMAKE_SYSTEM_NAME Linux)
-	SET(CMAKE_SYSTEM_VERSION Android)
-
-	SET(CMAKE_C_COMPILER   {PATH}/bin/arm-linux-androideabi-gcc)
-	SET(CMAKE_CXX_COMPILER {PATH}/bin/arm-linux-androideabi-g++)
-	SET(CMAKE_FIND_ROOT_PATH {PATH}/sysroot/)
-
-	SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
-	SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
-	SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
-
-Add `-DCMAKE_TOOLCHAIN_FILE={pathToToolchainFile}` to cmake command
-when configuring.
-
-MinGW
------
-
-If you want to build the library in MinGW environment with SSH support
-enabled, you may need to pass
-`-DCMAKE_LIBRARY_PATH="${MINGW_PREFIX}/${MINGW_CHOST}/lib/"` flag
-to CMake when configuring. This is because CMake cannot find the
-Win32 libraries in MinGW folders by default and you might see an
-error message stating that CMake could not resolve `ws2_32` library
-during configuration.
-
-Another option would be to install `msys2-w32api-runtime` package before
-configuring. This package installs the Win32 libraries into `/usr/lib`
-folder which is by default recognized as the library path by CMake.
-Please note though that this package is meant for MSYS subsystem which
-is different from MinGW.

-PCRE2 is a library of functions to support regular expressions whose syntax
-and semantics are as close as possible to those of the Perl 5 language.
-
-Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD"
-licence, as specified below, with one exemption for certain binary
-redistributions. The documentation for PCRE2, supplied in the "doc" directory,
-is distributed under the same terms as the software itself. The data in the
-testdata directory is not copyrighted and is in the public domain.
-
-The basic library functions are written in C and are freestanding. Also
-included in the distribution is a just-in-time compiler that can be used to
-optimize pattern matching. This is an optional feature that can be omitted when
-the library is built. The just-in-time compiler is separately licensed under the
-"2-clause BSD" licence.

-EXEMPTION FOR BINARY LIBRARY-LIKE PACKAGES
-------------------------------------------
-
-The second condition in the BSD licence (covering binary redistributions) does
-not apply all the way down a chain of software. If binary package A includes
-PCRE2, it must respect the condition, but if package B is software that
-includes package A, the condition is not imposed on package B unless it uses
-PCRE2 independently.

-          The posspropstab table has four entries per row. Each row relates to
-          one of PCRE's special properties such as ALNUM or SPACE or WORD.
-          Only WORD actually needs all four entries, but using repeats for the
-          others means they can all use the same code below.
-
-          The first two entries in each row are Unicode general categories, and
-          apply always, because all the characters they include are part of the
-          PCRE character set. The third and fourth entries are a general and a
-          particular category, respectively, that include one or more relevant
-          characters. One or the other is used, depending on whether the check
-          is for a general or a particular category. However, in both cases the
-          category contains more characters than the specials that are defined
-          for the property being tested against. Therefore, it cannot be used
-          in a NOTPROP case.
-
-          Example: the row for WORD contains ucp_L, ucp_N, ucp_P, ucp_Po.
-          Underscore is covered by ucp_P or ucp_Po. */

-/* This function is used to read numbers in the pattern. The initial pointer
-must be at the sign or first digit of the number. When relative values
-(introduced by + or -) are allowed, they are relative group numbers, and the
-result must be greater than zero.
-
-Arguments:
-  ptrptr      points to the character pointer variable
-  ptrend      points to the end of the input string
-  allow_sign  if < 0, sign not allowed; if >= 0, sign is relative to this
-  max_value   the largest number allowed;
-              you must not pass a value for max_value larger than
-              INT_MAX/10 - 1 because this function relies on max_value to
-              avoid integer overflow
-  max_error   the error to give for an over-large number
-  intptr      where to put the result
-  errcodeptr  where to put an error code
-
-Returns:      TRUE  - a number was read
-              FALSE - errorcode == 0 => no number was found
-                      errorcode != 0 => an error occurred

-    recommended to avoid the ambiguities in the old syntax.
-
-    Outside a character class, the digits are read as a decimal number. If the
-    number is less than 10, or if there are that many previous extracting left
-    brackets, it is a back reference. Otherwise, up to three octal digits are

-    (cf \0123, which is octal 012 followed by the literal 3). This is the "Perl
-    style" of handling ambiguous octal/backrefences such as \12.
-
-    There is an alternative disambiguation strategy, selected by
-    PCRE2_EXTRA_PYTHON_OCTAL, which follows Python's behaviour. An octal must
-    have either a leading zero, or exactly three octal digits; otherwise it's
-    a backreference. The disambiguation is stable, and does not depend on how
-    many capture groups are defined (it's simply an invalid backreference if
-    there is no corresponding capture group). Additionally, octal values above
-    \377 (\xff) are rejected.

-
-/* This function is called when the sequence "[:" or "[." or "[=" is
-encountered in a character class. It checks whether this is followed by a
-sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
-reach an unescaped ']' without the special preceding character, return FALSE.
-
-Originally, this function only recognized a sequence of letters between the
-terminators, but it seems that Perl recognizes any sequence of characters,
-though of course unknown POSIX names are subsequently rejected. Perl gives an
-"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
-didn't consider this to be a POSIX class. Likewise for [:1234:].
-
-The problem in trying to be exactly like Perl is in the handling of escapes. We
-have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
-class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
-below handles the special cases \\ and \], but does not try to do any other
-escape processing. This makes it different from Perl for cases such as
-[:l\ower:] where Perl recognizes it as the POSIX class "lower" but PCRE does
-not recognize "l\ower". This is a lesser evil than not diagnosing bad classes
-when Perl does, I think.
-
-A user pointed out that PCRE was rejecting [:a[:digit:]] whereas Perl was not.
-It seems that the appearance of a nested POSIX class supersedes an apparent
-external class. For example, [:a[:digit:]b:] matches "a", "b", ":", or
-a digit. This is handled by returning FALSE if the start of a new group with
-the same terminator is encountered, since the next closing sequence must close
-the nested group, not the outer one.
-
-In Perl, unescaped square brackets may also appear as part of class names. For
-example, [:a[:abc]b:] gives unknown POSIX class "[:abc]b:]". However, for
-[:a[:abc]b][b:] it gives unknown POSIX class "[:abc]b][b:]", which does not
-seem right at all. PCRE does not allow closing square brackets in POSIX class
-names.

-/* This module contains the external function pcre2_dfa_match(), which is an
-alternative matching function that uses a sort of DFA algorithm (not a true
-FSM). This is NOT Perl-compatible, but it has advantages in certain
-applications. */
-
-
-/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
-the performance of his patterns greatly. I could not use it as it stood, as it
-was not thread safe, and made assumptions about pattern sizes. Also, it caused
-test 7 to loop, and test 9 to crash with a segfault.
-
-The issue is the check for duplicate states, which is done by a simple linear
-search up the state list. (Grep for "duplicate" below to find the code.) For
-many patterns, there will never be many states active at one time, so a simple
-linear search is fine. In patterns that have many active states, it might be a
-bottleneck. The suggested code used an indexing scheme to remember which states
-had previously been used for each character, and avoided the linear search when
-it knew there was no chance of a duplicate. This was implemented when adding
-states to the state lists.
-
-I wrote some thread-safe, not-limited code to try something similar at the time
-of checking for duplicates (instead of when adding states), using index vectors
-on the stack. It did give a 13% improvement with one specially constructed
-pattern for certain subject strings, but on other strings and on many of the
-simpler patterns in the test suite it did worse. The major problem, I think,
-was the extra time to initialize the index. This had to be done for each call
-of internal_dfa_match(). (The supplied patch used a static vector, initialized
-only once - I suspect this was the cause of the problems with the tests.)
-
-Overall, I concluded that the gains in some cases did not outweigh the losses
-in others, so I abandoned this code. */

-*******************************************************************************
-                   "Recursion" in the match() function
-
-The original match() function was highly recursive, but this proved to be the
-source of a number of problems over the years, mostly because of the relatively
-small system stacks that are commonly found. As new features were added to
-patterns, various kludges were invented to reduce the amount of stack used,
-making the code hard to understand in places.
-
-A version did exist that used individual frames on the heap instead of calling
-match() recursively, but this ran substantially slower. The current version is
-a refactoring that uses a vector of frames to remember backtracking points.
-This runs no slower, and possibly even a bit faster than the original recursive
-implementation.
-
-At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50
-frames) was allocated on the system stack. If this was not big enough, the heap
-was used for a larger vector. However, it turns out that there are environments
-where taking as little as 20KiB from the system stack is an embarrassment.
-After another refactoring, the heap is used exclusively, but a pointer the
-frames vector and its size are cached in the match_data block, so that there is
-no new memory allocation if the same match_data block is used for multiple
-matches (unless the frames vector has to be extended).

-(i.e. something has been matched, even if not part of the actual matched
-string), or (b) the pattern contains a lookbehind. These are the conditions for
-which adding more characters may allow the current match to continue.
-
-For hard partial matching, we immediately return a partial match. Otherwise,
-carrying on means that a complete match on the current subject will be sought.
-A partial match is returned only if no complete match can be found. */

-      presence of the character in either case, not find the first occurrence.
-
-      The search can be skipped if the code unit was found later than the
-      current starting point in a previous iteration of the bumpalong loop.
-
-      HOWEVER: when the subject string is very, very long, searching to its end
-      can take a long time, and give bad performance on quite ordinary
-      anchored patterns. This showed up when somebody was matching something
-      like /^\d+C/ on a 32-megabyte string... so we don't do this when the
-      string is sufficiently long, but it's worth searching a lot more for

-10 and 11. The 2-dimensional table is indexed by the properties of two adjacent
-code points. The left property selects a word from the table, and the right
-property selects a bit from that word like this:
-
-  PRIV(ucp_gbtable)[left-property] & (1u << right-property)
-
-The value is non-zero if a grapheme break is NOT permitted between the relevant
-two code points. The breaking rules are as follows:
-
-1. Break at the start and end of text (pretty obviously).
-
-2. Do not break between a CR and LF; otherwise, break before and after
-   controls.
-
-3. Do not break Hangul syllable sequences, the rules for which are:
-
-    L may be followed by L, V, LV or LVT
-    LV or V may be followed by V or T
-    LVT or T may be followed by T
-
-4. Do not break before extending characters or zero-width-joiner (ZWJ).
-
-The following rules are only for extended grapheme clusters (but that's what we
-are implementing).
-
-5. Do not break before SpacingMarks.
-
-6. Do not break after Prepend characters.
-
-7. Do not break within emoji modifier sequences or emoji zwj sequences. That
-   is, do not break between characters with the Extended_Pictographic property
-   if a ZWJ intervenes. Extend characters are allowed between the characters;
-   this cannot be represented in this table, the code has to deal with it.
-
-8. Do not break within emoji flag sequences. That is, do not break between
-   regional indicator (RI) symbols if there are an odd number of RI characters

-			LINKING EXCEPTION
-
- In addition to the permissions in the GNU General Public License,

- version of this library into combinations with other programs,
- and to distribute those combinations without any restriction
- coming from the use of this file.  (The General Public License

-
-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  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
-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 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 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.
-
-  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.
-
-  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.
-
-  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.
-
-		    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.
-
-  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
-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.
-
-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.
-
-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.
-
-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.
-
-  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 a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-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.
-
-  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.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-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 this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-                  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, 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 library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete 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 distribute a copy of this License along with the
-Library.
-
-  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 Library or any portion
-of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-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 Library, 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 Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you 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.
-
-  If distribution of 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 satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be 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.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library 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.
-
-  9. 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 Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-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 with
-this License.
-
-  11. 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
-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 Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library 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 Library.
-
-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.
-
-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.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library 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.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser 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 Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-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.
-
-                            NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

-                  GNU LESSER GENERAL PUBLIC LICENSE
-                       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-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 this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-                  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, 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 library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete 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 distribute a copy of this License along with the
-Library.
-
-  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 Library or any portion
-of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-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 Library, 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 Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you 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.
-
-  If distribution of 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 satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be 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.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library 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.
-
-  9. 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 Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-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 with
-this License.
-
-  11. 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
-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 Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library 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 Library.
-
-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.
-
-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.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library 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.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser 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 Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-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.
-
-                            NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

- * The basic idea of patience diff is to find lines that are unique in

- * The maximal ordered sequence of such line pairs (where ordered means

- *
- * Now, the algorithm tries to extend the set of common lines by growing
- * the line ranges where the files have identical lines.

-  A CRC of a message is computed on N braids of words in the message, where
-  each word consists of W bytes (4 or 8). If N is 3, for example, then three
-  running sparse CRCs are calculated respectively on each braid, at these
-  indices in the array of words: 0, 3, 6, ..., 1, 4, 7, ..., and 2, 5, 8, ...
-  This is done starting at a word boundary, and continues until as many blocks
-  of N * W bytes as are available have been processed. The results are combined
-  into a single CRC at the end. For this code, N must be in the range 1..6 and
-  W must be 4 or 8. The upper limit on N can be increased if desired by adding
-  more #if blocks, extending the patterns apparent in the code. In addition,
-  crc32.h would need to be regenerated, if the maximum N value is increased.
-

-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit. Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by

-  byte 0xb1 is the polynomial x^7+x^3+x^2+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder. The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
-  (which is shifting right by one and adding x^32 mod p if the bit shifted out
-  is a one). We start with the highest power (least significant bit) of q and
-  repeat for all eight bits of q.
-
-  The table is simply the CRC of all possible eight bit values. This is all the
-  information needed to generate CRCs on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.

-/*
- *  ALGORITHM
- *
- *      The "deflation" process depends on being able to identify portions
- *      of the input text which are identical to earlier input (within a
- *      sliding window trailing behind the input currently being processed).
- *
- *      The most straightforward technique turns out to be the fastest for
- *      most input files: try all possible matches and select the longest.
- *      The key feature of this algorithm is that insertions into the string
- *      dictionary are very simple and thus fast, and deletions are avoided
- *      completely. Insertions are performed at each input character, whereas
- *      string matches are performed only when the previous match ends. So it
- *      is preferable to spend more time in matches to allow very fast string
- *      insertions and avoid deletions. The matching algorithm for small
- *      strings is inspired from that of Rabin & Karp. A brute force approach
- *      is used to find longer strings when a small match has been found.
- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- *      (by Leonid Broukhis).
- *         A previous version of this file used a more sophisticated algorithm
- *      (by Fiala and Greene) which is guaranteed to run in linear amortized
- *      time, but has a larger average cost, uses more memory and is patented.
- *      However the F&G algorithm may be faster for some highly redundant
- *      files if the parameter max_chain_length (described below) is too large.
- *
- *  ACKNOWLEDGEMENTS
- *
- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- *      I found it in 'freeze' written by Leonid Broukhis.
- *      Thanks to many people for bug reports and testing.

-     *
-     * Analysis: The longest fixed codes are a length code of 8 bits plus 5
-     * extra bits, for lengths 131 to 257. The longest fixed distance codes are
-     * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest
-     * possible fixed-codes length/distance pair is then 31 bits total.
-     *
-     * sym_buf starts one-fourth of the way into pending_buf. So there are
-     * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
-     * in sym_buf is three bytes -- two for the distance and one for the
-     * literal/length. As each symbol is consumed, the pointer to the next
-     * sym_buf value to read moves forward three bytes. From that symbol, up to
-     * 31 bits are written to pending_buf. The closest the written pending_buf
-     * bits gets to the next sym_buf symbol to read is just before the last
-     * code is written. At that time, 31*(n - 2) bits have been written, just
-     * after 24*(n - 2) bits have been consumed from sym_buf. sym_buf starts at
-     * 8*n bits into pending_buf. (Note that the symbol buffer fills when n - 1
-     * symbols are written.) The closest the writing gets to what is unread is
-     * then n + 14 bits. Here n is lit_bufsize, which is 16384 by default, and
-     * can range from 128 to 32768.
-     *
-     * Therefore, at a minimum, there are 142 bits of space between what is
-     * written and what is read in the overlain buffers, so the symbols cannot
-     * be overwritten by the compressed data. That space is actually 139 bits,
-     * due to the three-bit fixed-code block header.
-     *
-     * That covers the case where either Z_FIXED is specified, forcing fixed
-     * codes, or when the use of fixed codes is chosen, because that choice
-     * results in a smaller compressed block than dynamic codes. That latter
-     * condition then assures that the above analysis also covers all dynamic
-     * blocks. A dynamic-code block will only be chosen to be emitted if it has
-     * fewer bits than a fixed-code block would for the same set of symbols.
-     * Therefore its average symbol length is assured to be less than 31. So
-     * the compressed data for a dynamic block also cannot overwrite the
-     * symbols from which it is being constructed.

-   returns, strm will also provide an error message.
-
-   in() and out() are the call-back input and output functions.  When
-   inflateBack() needs more input, it calls in().  When inflateBack() has
-   filled the window with output, or when it completes with data in the
-   window, it calls out() to write out the data.  The application must not
-   change the provided input until in() is called again or inflateBack()
-   returns.  The application must not change the window/output buffer until
-   inflateBack() returns.
-
-   in() and out() are called with a descriptor parameter provided in the
-   inflateBack() call.  This parameter can be a structure that provides the
-   information required to do the read or write, as well as accumulated
-   information on the input and output such as totals and check values.
-
-   in() should return zero on failure.  out() should return non-zero on
-   failure.  If either in() or out() fails, than inflateBack() returns a
-   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
-   was in() or out() that caused in the error.  Otherwise,  inflateBack()
-   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
-   error, or Z_MEM_ERROR if it could not allocate memory for the state.

-   Decode literal, length, and distance codes and write out the resulting
-   literal and match bytes until either not enough input or output is
-   available, an end-of-block is encountered, or a data error is encountered.
-   When large enough input and output buffers are supplied to inflate(), for
-   example, a 16K input buffer and a 64K output buffer, more than 95% of the
-   inflate execution time is spent in this routine.
-
-   Entry assumptions:
-
-        state->mode == LEN
-        strm->avail_in >= 6
-        strm->avail_out >= 258
-        start >= strm->avail_out
-        state->bits < 8
-
-   On return, state->mode is one of:
-
-        LEN -- ran out of enough output space or enough available input
-        TYPE -- reached end of block code, inflate() to interpret next block
-        BAD -- error in block data
-
-   Notes:
-
-    - The maximum input bits used by a length/distance pair is 15 bits for the
-      length code, 5 bits for the length extra, 15 bits for the distance code,
-      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
-      Therefore if strm->avail_in >= 6, then there is enough input to avoid
-      checking for available input while decoding.
-
-    - The maximum bytes that a single length/distance pair can output is 258
-      bytes, which is the maximum length that can be coded.  inflate_fast()
-      requires strm->avail_out >= 258 for each loop to avoid checking for
-      output space.

-/* inflate.c -- zlib decompression
- * Copyright (C) 1995-2022 Mark Adler
- * For conditions of distribution and use, see copyright notice in zlib.h
- */
-
-/*
- * Change history:
- *
- * 1.2.beta0    24 Nov 2002
- * - First version -- complete rewrite of inflate to simplify code, avoid
- *   creation of window when not needed, minimize use of window when it is
- *   needed, make inffast.c even faster, implement gzip decoding, and to
- *   improve code readability and style over the previous zlib inflate code
- *
- * 1.2.beta1    25 Nov 2002
- * - Use pointers for available input and output checking in inffast.c
- * - Remove input and output counters in inffast.c
- * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
- * - Remove unnecessary second byte pull from length extra in inffast.c
- * - Unroll direct copy to three copies per loop in inffast.c
- *
- * 1.2.beta2    4 Dec 2002
- * - Change external routine names to reduce potential conflicts
- * - Correct filename to inffixed.h for fixed tables in inflate.c
- * - Make hbuf[] unsigned char to match parameter type in inflate.c
- * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
- *   to avoid negation problem on Alphas (64 bit) in inflate.c
- *
- * 1.2.beta3    22 Dec 2002
- * - Add comments on state->bits assertion in inffast.c
- * - Add comments on op field in inftrees.h
- * - Fix bug in reuse of allocated window after inflateReset()
- * - Remove bit fields--back to byte structure for speed
- * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
- * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
- * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
- * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
- * - Use local copies of stream next and avail values, as well as local bit
- *   buffer and bit count in inflate()--for speed when inflate_fast() not used
- *
- * 1.2.beta4    1 Jan 2003
- * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
- * - Move a comment on output buffer sizes from inffast.c to inflate.c
- * - Add comments in inffast.c to introduce the inflate_fast() routine
- * - Rearrange window copies in inflate_fast() for speed and simplification
- * - Unroll last copy for window match in inflate_fast()
- * - Use local copies of window variables in inflate_fast() for speed
- * - Pull out common wnext == 0 case for speed in inflate_fast()
- * - Make op and len in inflate_fast() unsigned for consistency
- * - Add FAR to lcode and dcode declarations in inflate_fast()
- * - Simplified bad distance check in inflate_fast()
- * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
- *   source file infback.c to provide a call-back interface to inflate for
- *   programs like gzip and unzip -- uses window as output buffer to avoid
- *   window copying
- *
- * 1.2.beta5    1 Jan 2003
- * - Improved inflateBack() interface to allow the caller to provide initial
- *   input in strm.
- * - Fixed stored blocks bug in inflateBack()
- *
- * 1.2.beta6    4 Jan 2003
- * - Added comments in inffast.c on effectiveness of POSTINC
- * - Typecasting all around to reduce compiler warnings
- * - Changed loops from while (1) or do {} while (1) to for (;;), again to
- *   make compilers happy
- * - Changed type of window in inflateBackInit() to unsigned char *
- *
- * 1.2.beta7    27 Jan 2003
- * - Changed many types to unsigned or unsigned short to avoid warnings
- * - Added inflateCopy() function
- *
- * 1.2.0        9 Mar 2003
- * - Changed inflateBack() interface to provide separate opaque descriptors
- *   for the in() and out() functions
- * - Changed inflateBack() argument and in_func typedef to swap the length
- *   and buffer address return values for the input function
- * - Check next_in and next_out for Z_NULL on entry to inflate()
- *
- * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

-   inflate() uses a state machine to process as much input data and generate as
-   much output data as possible before returning.  The state machine is
-   structured roughly as follows:
-
-    for (;;) switch (state) {
-    ...
-    case STATEn:
-        if (not enough input data or output space to make progress)
-            return;
-        ... make progress ...
-        state = STATEm;
-        break;
-    ...
-    }
-
-   so when inflate() is called again, the same case is attempted again, and
-   if the appropriate resources are provided, the machine proceeds to the
-   next state.  The NEEDBITS() macro is usually the way the state evaluates
-   whether it can proceed or should return.  NEEDBITS() does the return if
-   the requested bits are not available.  The typical use of the BITS macros
-   is:
-
-        NEEDBITS(n);
-        ... do something with BITS(n) ...
-        DROPBITS(n);
-
-   where NEEDBITS(n) either returns from inflate() if there isn't enough
-   input left to load n bits into the accumulator, or it continues.  BITS(n)
-   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
-   the low n bits off the accumulator.  INITBITS() clears the accumulator
-   and sets the number of available bits to zero.  BYTEBITS() discards just
-   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
-   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
-
-   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
-   if there is no input available.  The decoding of variable length codes uses
-   PULLBYTE() directly in order to pull just enough bytes to decode the next
-   code, and no more.
-
-   Some states loop until they get enough input, making sure that enough
-   state information is maintained to continue the loop where it left off
-   if NEEDBITS() returns in the loop.  For example, want, need, and keep
-   would all have to actually be part of the saved state in case NEEDBITS()
-   returns:
-
-    case STATEw:
-        while (want < need) {
-            NEEDBITS(n);
-            keep[want++] = BITS(n);
-            DROPBITS(n);
-        }
-        state = STATEx;
-    case STATEx:
-
-   As shown above, if the next state is also the next case, then the break
-   is omitted.
-
-   A state may also return if there is not enough output space available to
-   complete that state.  Those states are copying stored data, writing a
-   literal byte, and copying a matching string.
-
-   When returning, a "goto inf_leave" is used to update the total counters,
-   update the check value, and determine whether any progress has been made
-   during that inflate() call in order to return the proper return code.
-   Progress is defined as a change in either strm->avail_in or strm->avail_out.
-   When there is a window, goto inf_leave will update the window with the last
-   output written.  If a goto inf_leave occurs in the middle of decompression
-   and there is no window currently, goto inf_leave will create one and copy
-   output to the window for the next call of inflate().
-
-   In this implementation, the flush parameter of inflate() only affects the
-   return code (per zlib.h).  inflate() always writes as much as possible to
-   strm->next_out, given the space available and the provided input--the effect
-   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
-   the allocation of and copying into a sliding window until necessary, which
-   provides the effect documented in zlib.h for Z_FINISH when the entire input
-   stream available.  So the only thing the flush parameter actually does is:
-   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
-   will return Z_BUF_ERROR if it has not reached the end of the stream.

-       code lengths are lens[0..codes-1].  Each length corresponds to the
-       symbols 0..codes-1.  The Huffman code is generated by first sorting the
-       symbols by length from short to long, and retaining the symbol order
-       for codes with equal lengths.  Then the code starts with all zero bits
-       for the first code of the shortest length, and the codes are integer
-       increments for the same length, and zeros are appended as the length
-       increases.  For the deflate format, these bits are stored backwards
-       from their more natural integer increment ordering, and so when the
-       decoding tables are built in the large loop below, the integer codes
-       are incremented backwards.
-
-       This routine assumes, but does not check, that all of the entries in
-       lens[] are in the range 0..MAXBITS.  The caller must assure this.
-       1..MAXBITS is interpreted as that code length.  zero means that that
-       symbol does not occur in this code.
-
-       The codes are sorted by computing a count of codes for each length,
-       creating from that a table of starting indices for each length in the
-       sorted table, and then entering the symbols in order in the sorted
-       table.  The sorted table is work[], with that space being provided by
-       the caller.
-
-       The length counts are used for other purposes as well, i.e. finding
-       the minimum and maximum length codes, determining if there are any
-       codes at all, checking for a valid set of lengths, and looking ahead
-       at length counts to determine sub-table sizes when building the

-       all codes of length max, i.e. all codes, have been processed.  This

- *      Each code tree is stored in a compressed form which is itself

-    The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed data.
-  This version of the library supports only one compression method (deflation)
-  but other algorithms will be added later and will have the same stream
-  interface.
-
-    Compression can be done in a single step if the buffers are large enough,
-  or can be done by repeated calls of the compression function.  In the latter
-  case, the application must provide more input and/or consume the output
-  (providing more output space) before each call.
-
-    The compressed data format used by default by the in-memory functions is
-  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
-  around a deflate stream, which is itself documented in RFC 1951.
-
-    The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio using the functions that start
-  with "gz".  The gzip format is different from the zlib format.  gzip is a
-  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
-    This library can optionally read and write gzip and raw deflate streams in
-  memory as well.
-
-    The zlib format was designed to be compact and fast for use in memory
-  and on communications channels.  The gzip format was designed for single-
-  file compression on file systems, has a larger header than zlib to maintain
-  directory information, and uses a different, slower check method than zlib.
-
-    The library does not install any signal handler.  The decoder checks
-  the consistency of the compressed data, so the library should never crash
-  even in the case of corrupted input.

-     The application must update next_in and avail_in when avail_in has dropped
-   to zero.  It must update next_out and avail_out when avail_out has dropped
-   to zero.  The application must initialize zalloc, zfree and opaque before
-   calling the init function.  All other fields are set by the compression
-   library and must not be updated by the application.
-
-     The opaque value provided by the application will be passed as the first
-   parameter for calls of zalloc and zfree.  This can be useful for custom
-   memory management.  The compression library attaches no meaning to the
-   opaque value.
-
-     zalloc must return Z_NULL if there is not enough memory for the object.
-   If zlib is used in a multi-threaded application, zalloc and zfree must be
-   thread safe.  In that case, zlib is thread-safe.  When zalloc and zfree are
-   Z_NULL on entry to the initialization function, they are set to internal
-   routines that use the standard library functions malloc() and free().
-
-     On 16-bit systems, the functions zalloc and zfree must be able to allocate
-   exactly 65536 bytes, but will not be required to allocate more than this if
-   the symbol MAXSEG_64K is defined (see zconf.h).  WARNING: On MSDOS, pointers
-   returned by zalloc for objects of exactly 65536 bytes *must* have their
-   offset normalized to zero.  The default allocation function provided by this
-   library ensures this (see zutil.c).  To reduce memory requirements and avoid
-   any allocation of 64K objects, at the expense of compression ratio, compile
-   the library with -DMAX_WBITS=14 (see zconf.h).
-
-     The fields total_in and total_out can be used for statistics or progress

-ZEXTERN int ZEXPORT deflate(z_streamp strm, int flush);
-/*
-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows.  deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Generate more output starting at next_out and update next_out and avail_out
-    accordingly.  This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary.  Some output may be provided even if
-    flush is zero.
-
-    Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating avail_in or avail_out accordingly; avail_out should
-  never be zero before the call.  The application can consume the compressed
-  output when it wants, for example when the output buffer is full (avail_out
-  == 0), or after each call of deflate().  If deflate returns Z_OK and with
-  zero avail_out, it must be called again after making room in the output
-  buffer because there might be more output pending. See deflatePending(),
-  which can be used if desired to determine whether or not there is more output
-  in that case.
-
-    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
-  decide how much data to accumulate before producing output, in order to
-  maximize compression.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far.  (In
-  particular avail_in is zero after the call if enough output space has been
-  provided before the call.) Flushing may degrade compression for some
-  compression algorithms and so it should be used only when necessary.  This
-  completes the current deflate block and follows it with an empty stored block
-  that is three bits plus filler bits to the next byte, followed by four bytes
-  (00 00 ff ff).
-
-    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
-  output buffer, but the output is not aligned to a byte boundary.  All of the
-  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
-  This completes the current deflate block and follows it with an empty fixed
-  codes block that is 10 bits long.  This assures that enough bytes are output
-  in order for the decompressor to finish the block before the empty fixed
-  codes block.
-
-    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
-  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
-  seven bits of the current block are held to be written as the next byte after
-  the next deflate block is completed.  In this case, the decompressor may not
-  be provided enough bits at this point in order to complete decompression of
-  the data provided so far to the compressor.  It may need to wait for the next
-  block to be emitted.  This is for advanced applications that need to control
-  the emission of deflate blocks.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
-  compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
-  avail_out is greater than six when the flush marker begins, in order to avoid
-  repeated flush markers upon calling deflate() again when avail_out == 0.
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there was
-  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
-  function must be called again with Z_FINISH and more output space (updated
-  avail_out) but no more input data, until it returns with Z_STREAM_END or an
-  error.  After deflate has returned Z_STREAM_END, the only possible operations
-  on the stream are deflateReset or deflateEnd.
-
-    Z_FINISH can be used in the first deflate call after deflateInit if all the
-  compression is to be done in a single step.  In order to complete in one
-  call, avail_out must be at least the value returned by deflateBound (see
-  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
-  output space is provided, deflate will not return Z_STREAM_END, and it must
-  be called again as described above.
-
-    deflate() sets strm->adler to the Adler-32 checksum of all input read
-  so far (that is, total_in bytes).  If a gzip stream is being generated, then
-  strm->adler will be the CRC-32 checksum of the input read so far.  (See
-  deflateInit2 below.)
-
-    deflate() may update strm->data_type if it can make a good guess about
-  the input data type (Z_BINARY or Z_TEXT).  If in doubt, the data is
-  considered binary.  This field is only for information purposes and does not
-  affect the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
-  if next_in or next_out was Z_NULL or the state was inadvertently written over
-  by the application), or Z_BUF_ERROR if no progress is possible (for example
-  avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not fatal, and
-  deflate() can be called again with more input and more output space to
-  continue compressing.

-    inflate decompresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-  The detailed semantics are as follows.  inflate performs one or both of the
-  following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), then next_in and avail_in are updated

-
-  - Generate more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() provides as much output as possible, until there is
-    no more input data or no more space in the output buffer (see below about
-    the flush parameter).
-
-    Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating the next_* and avail_* values accordingly.  If the
-  caller of inflate() does not provide both available input and available
-  output space, it is possible that there will be no progress made.  The
-  application can consume the uncompressed output when it wants, for example
-  when the output buffer is full (avail_out == 0), or after each call of
-  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
-  called again after making room in the output buffer because there might be
-  more output pending.
-
-    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
-  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
-  output as possible to the output buffer.  Z_BLOCK requests that inflate()
-  stop if and when it gets to the next deflate block boundary.  When decoding
-  the zlib or gzip format, this will cause inflate() to return immediately
-  after the header and before the first block.  When doing a raw inflate,
-  inflate() will go ahead and process the first block, and will return when it
-  gets to the end of that block, or when it runs out of data.
-
-    The Z_BLOCK option assists in appending to or combining deflate streams.
-  To assist in this, on return inflate() always sets strm->data_type to the
-  number of unused bits in the last byte taken from strm->next_in, plus 64 if
-  inflate() is currently decoding the last block in the deflate stream, plus
-  128 if inflate() returned immediately after decoding an end-of-block code or
-  decoding the complete header up to just before the first byte of the deflate
-  stream.  The end-of-block will not be indicated until all of the uncompressed
-  data from that block has been written to strm->next_out.  The number of
-  unused bits may in general be greater than seven, except when bit 7 of
-  data_type is set, in which case the number of unused bits will be less than
-  eight.  data_type is set as noted here every time inflate() returns for all
-  flush options, and so can be used to determine the amount of currently
-  consumed input in bits.
-
-    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
-  end of each deflate block header is reached, before any actual data in that
-  block is decoded.  This allows the caller to determine the length of the
-  deflate block header for later use in random access within a deflate block.
-  256 is added to the value of strm->data_type when inflate() returns
-  immediately after reaching the end of the deflate block header.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error.  However if all decompression is to be performed in a single step (a
-  single call of inflate), the parameter flush should be set to Z_FINISH.  In
-  this case all pending input is processed and all pending output is flushed;
-  avail_out must be large enough to hold all of the uncompressed data for the
-  operation to complete.  (The size of the uncompressed data may have been
-  saved by the compressor for this purpose.)  The use of Z_FINISH is not
-  required to perform an inflation in one step.  However it may be used to
-  inform inflate that a faster approach can be used for the single inflate()
-  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
-  stream completes, which reduces inflate's memory footprint.  If the stream
-  does not complete, either because not all of the stream is provided or not
-  enough output space is provided, then a sliding window will be allocated and
-  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
-  been used.
-
-     In this implementation, inflate() always flushes as much output as
-  possible to the output buffer, and always uses the faster approach on the
-  first call.  So the effects of the flush parameter in this implementation are
-  on the return value of inflate() as noted below, when inflate() returns early
-  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
-  memory for a sliding window when Z_FINISH is used.
-
-     If a preset dictionary is needed after this call (see inflateSetDictionary
-  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
-  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
-  strm->adler to the Adler-32 checksum of all output produced so far (that is,
-  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
-  below.  At the end of the stream, inflate() checks that its computed Adler-32
-  checksum is equal to that saved by the compressor and returns Z_STREAM_END
-  only if the checksum is correct.
-
-    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
-  deflate data.  The header type is detected automatically, if requested when
-  initializing with inflateInit2().  Any information contained in the gzip
-  header is not retained unless inflateGetHeader() is used.  When processing
-  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
-  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
-  uncompressed length, modulo 2^32.
-
-    inflate() returns Z_OK if some progress has been made (more input processed
-  or more output produced), Z_STREAM_END if the end of the compressed data has
-  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-  corrupted (input stream not conforming to the zlib format or incorrect check
-  value, in which case strm->msg points to a string with a more specific
-  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
-  next_in or next_out was Z_NULL, or the state was inadvertently written over
-  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
-  if no progress was possible or if there was not enough room in the output
-  buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
-  inflate() can be called again with more input and more output space to
-  continue decompressing.  If Z_DATA_ERROR is returned, the application may
-  then call inflateSync() to look for a good compression block if a partial
-  recovery of the data is to be attempted.

-
-     This is another version of deflateInit with more compression options.  The
-   fields zalloc, zfree and opaque must be initialized before by the caller.
-
-     The method parameter is the compression method.  It must be Z_DEFLATED in
-   this version of the library.
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library.  Larger values of this parameter result in better
-   compression at the expense of memory usage.  The default value is 15 if
-   deflateInit is used instead.
-
-     For the current implementation of deflate(), a windowBits value of 8 (a
-   window size of 256 bytes) is not supported.  As a result, a request for 8
-   will result in 9 (a 512-byte window).  In that case, providing 8 to
-   inflateInit2() will result in an error when the zlib header with 9 is
-   checked against the initialization of inflate().  The remedy is to not use 8
-   with deflateInit2() with this initialization, or at least in that case use 9
-   with inflateInit2().
-
-     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
-   determines the window size.  deflate() will then generate raw deflate data
-   with no zlib header or trailer, and will not compute a check value.
-
-     windowBits can also be greater than 15 for optional gzip encoding.  Add
-   16 to windowBits to write a simple gzip header and trailer around the
-   compressed data instead of a zlib wrapper.  The gzip header will have no
-   file name, no extra data, no comment, no modification time (set to zero), no
-   header crc, and the operating system will be set to the appropriate value,
-   if the operating system was determined at compile time.  If a gzip stream is
-   being written, strm->adler is a CRC-32 instead of an Adler-32.
-
-     For raw deflate or gzip encoding, a request for a 256-byte window is
-   rejected as invalid, since only the zlib header provides a means of
-   transmitting the window size to the decompressor.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state.  memLevel=1 uses minimum memory but is
-   slow and reduces compression ratio; memLevel=9 uses maximum memory for
-   optimal speed.  The default value is 8.  See zconf.h for total memory usage
-   as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm.  Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match), or Z_RLE to limit match distances to one (run-length
-   encoding).  Filtered data consists mostly of small values with a somewhat
-   random distribution.  In this case, the compression algorithm is tuned to
-   compress them better.  The effect of Z_FILTERED is to force more Huffman
-   coding and less string matching; it is somewhat intermediate between
-   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
-   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
-   strategy parameter only affects the compression ratio but not the
-   correctness of the compressed output even if it is not set appropriately.
-   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
-   decoder for special applications.
-
-     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
-   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
-   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
-   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
-   set to null if there is no error message.  deflateInit2 does not perform any
-   compression: this will be done by deflate().

-   options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH.  The
-   compressor and decompressor must use exactly the same dictionary (see
-   inflateSetDictionary).
-
-     The dictionary should consist of strings (byte sequences) that are likely
-   to be encountered later in the data to be compressed, with the most commonly
-   used strings preferably put towards the end of the dictionary.  Using a

-   predicted with good accuracy; the data can then be compressed better than
-   with the default empty dictionary.
-
-     Depending on the size of the compression data structures selected by

-   discarded, for example if the dictionary is larger than the window size
-   provided in deflateInit or deflateInit2.  Thus the strings most likely to be
-   useful should be put at the end of the dictionary, not at the front.  In
-   addition, the current implementation of deflate will use at most the window
-   size minus 262 bytes of the provided dictionary.
-
-     Upon return of this function, strm->adler is set to the Adler-32 value

-   which dictionary has been used by the compressor.  (The Adler-32 value
-   applies to the whole dictionary even if only a subset of the dictionary is
-   actually used by the compressor.) If a raw deflate was requested, then the
-   Adler-32 value is not computed and strm->adler is not set.

-     This is another version of inflateInit with an extra parameter.  The

-   before by the caller.
-
-     The windowBits parameter is the base two logarithm of the maximum window
-   size (the size of the history buffer).  It should be in the range 8..15 for
-   this version of the library.  The default value is 15 if inflateInit is used
-   instead.  windowBits must be greater than or equal to the windowBits value
-   provided to deflateInit2() while compressing, or it must be equal to 15 if
-   deflateInit2() was not used.  If a compressed stream with a larger window
-   size is given as input, inflate() will return with the error code
-   Z_DATA_ERROR instead of trying to allocate a larger window.
-
-     windowBits can also be zero to request that inflate use the window size in
-   the zlib header of the compressed stream.
-
-     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
-   determines the window size.  inflate() will then process raw deflate data,
-   not looking for a zlib or gzip header, not generating a check value, and not
-   looking for any check values for comparison at the end of the stream.  This
-   is for use with other formats that use the deflate compressed data format
-   such as zip.  Those formats provide their own check values.  If a custom
-   format is developed using the raw deflate format for compressed data, it is
-   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
-   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
-   most applications, the zlib format should be used as is.  Note that comments
-   above on the use in deflateInit2() applies to the magnitude of windowBits.
-
-     windowBits can also be greater than 15 for optional gzip decoding.  Add
-   32 to windowBits to enable zlib and gzip decoding with automatic header
-   detection, or add 16 to decode only the gzip format (the zlib format will
-   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
-   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
-   below), inflate() will *not* automatically decode concatenated gzip members.
-   inflate() will return Z_STREAM_END at the end of the gzip member.  The state
-   would need to be reset to continue decoding a subsequent gzip member.  This
-   *must* be done if there is more data after a gzip member, in order for the
-   decompression to be compliant with the gzip standard (RFC 1952).

-   inflate() for file i/o applications, in that it avoids copying between the
-   output and the sliding window by simply making the window itself the output
-   buffer.  inflate() can be faster on modern CPUs when used with large
-   buffers.  inflateBack() trusts the application to not change the output
-   buffer passed by the output function, at least until inflateBack() returns.
-
-     inflateBackInit() must be called first to allocate the internal state
-   and to initialize the state with the user-provided window buffer.
-   inflateBack() may then be used multiple times to inflate a complete, raw
-   deflate stream with each call.  inflateBackEnd() is then called to free the
-   allocated state.
-
-     A raw deflate stream is one with no zlib or gzip header or trailer.
-   This routine would normally be used in a utility that reads zip or gzip
-   files and writes out uncompressed files.  The utility would decode the
-   header and process the trailer on its own, hence this routine expects only
-   the raw deflate stream to decompress.  This is different from the default
-   behavior of inflate(), which expects a zlib header and trailer around the
-   deflate stream.
-
-     inflateBack() uses two subroutines supplied by the caller that are then
-   called by inflateBack() for input and output.  inflateBack() calls those
-   routines until it reads a complete deflate stream and writes out all of the
-   uncompressed data, or until it encounters an error.  The function's
-   parameters and return types are defined above in the in_func and out_func
-   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
-   number of bytes of provided input, and a pointer to that input in buf.  If
-   there is no input available, in() must return zero -- buf is ignored in that
-   case -- and inflateBack() will return a buffer error.  inflateBack() will
-   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
-   out() should return zero on success, or non-zero on failure.  If out()
-   returns non-zero, inflateBack() will return with an error.  Neither in() nor
-   out() are permitted to change the contents of the window provided to
-   inflateBackInit(), which is also the buffer that out() uses to write from.
-   The length written by out() will be at most the window size.  Any non-zero
-   amount of input may be provided by in().
-
-     For convenience, inflateBack() can be provided input on the first call by
-   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
-   in() will be called.  Therefore strm->next_in must be initialized before
-   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
-   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
-   must also be initialized, and then if strm->avail_in is not zero, input will
-   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
-
-     The in_desc and out_desc parameters of inflateBack() is passed as the
-   first parameter of in() and out() respectively when they are called.  These
-   descriptors can be optionally used to pass any information that the caller-
-   supplied in() and out() functions need to do their job.
-
-     On return, inflateBack() will set strm->next_in and strm->avail_in to
-   pass back any unused input that was provided by the last in() call.  The
-   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
-   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
-   in the deflate stream (in which case strm->msg is set to indicate the nature
-   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
-   In the case of Z_BUF_ERROR, an input or output error can be distinguished
-   using strm->next_in which will be Z_NULL only if in() returned an error.  If
-   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
-   non-zero.  (in() will always be called before out(), so strm->next_in is
-   assured to be defined if out() returns non-zero.)  Note that inflateBack()
-   cannot return Z_OK.

-
-     "a" can be used instead of "w" to request that the gzip stream that will

- * - `GIT_CHECKOUT_FORCE` will take any action to make the working
- *   directory match the target (including potentially discarding
- *   modified files).
- *
- * To emulate `git checkout`, use `GIT_CHECKOUT_SAFE` with a checkout
- * notification callback (see below) that displays information about dirty
- * files.  The default behavior will cancel checkout on conflicts.
- *
- * To emulate `git checkout-index`, use `GIT_CHECKOUT_SAFE` with a
- * notification callback that cancels the operation if a dirty-but-existing
- * file is found in the working directory.  This core git command isn't
- * quite "force" but is sensitive about some types of changes.
- *
- * To emulate `git checkout -f`, use `GIT_CHECKOUT_FORCE`.
- *
- *
- * There are some additional flags to modify the behavior of checkout:
- *
- * - `GIT_CHECKOUT_DRY_RUN` is a dry-run strategy that checks for conflicts,
- *   etc., but doesn't make any actual changes.
- *
- * - GIT_CHECKOUT_ALLOW_CONFLICTS makes SAFE mode apply safe file updates
- *   even if there are conflicts (instead of cancelling the checkout).
- *
- * - GIT_CHECKOUT_REMOVE_UNTRACKED means remove untracked files (i.e. not
- *   in target, baseline, or index, and not ignored) from the working dir.
- *
- * - GIT_CHECKOUT_REMOVE_IGNORED means remove ignored files (that are also
- *   untracked) from the working directory as well.
- *
- * - GIT_CHECKOUT_UPDATE_ONLY means to only update the content of files that
- *   already exist.  Files will not be created nor deleted.  This just skips
- *   applying adds, deletes, and typechanges.
- *
- * - GIT_CHECKOUT_DONT_UPDATE_INDEX prevents checkout from writing the
- *   updated files' information to the index.
- *
- * - Normally, checkout will reload the index and git attributes from disk
- *   before any operations.  GIT_CHECKOUT_NO_REFRESH prevents this reload.
- *
- * - Unmerged index entries are conflicts.  GIT_CHECKOUT_SKIP_UNMERGED skips
- *   files with unmerged index entries instead.  GIT_CHECKOUT_USE_OURS and
- *   GIT_CHECKOUT_USE_THEIRS to proceed with the checkout using either the
- *   stage 2 ("ours") or stage 3 ("theirs") version of files in the index.
- *
- * - GIT_CHECKOUT_DONT_OVERWRITE_IGNORED prevents ignored files from being
- *   overwritten.  Normally, files that are ignored in the working directory
- *   are not considered "precious" and may be overwritten if the checkout
- *   target contains that file.
- *
- * - GIT_CHECKOUT_DONT_REMOVE_EXISTING prevents checkout from removing
- *   files or folders that fold to the same name on case insensitive
- *   filesystems.  This can cause files to retain their existing names
- *   and write through existing symbolic links.

- * A `delta` is a file pair with an old and new revision.  The old version
- * may be absent if the file was just created and the new version may be
- * absent if the file was deleted.  A diff is mostly just a list of deltas.
- *
- * When iterating over a diff, this will be passed to most callbacks and
- * you can use the contents to understand exactly what has changed.
- *
- * The `old_file` represents the "from" side of the diff and the `new_file`
- * represents to "to" side of the diff.  What those means depend on the
- * function that was used to generate the diff and will be documented below.
- * You can also use the `GIT_DIFF_REVERSE` flag to flip it around.
- *
- * Although the two sides of the delta are named "old_file" and "new_file",
- * they actually may correspond to entries that represent a file, a symbolic
- * link, a submodule commit id, or even a tree (if you are tracking type
- * changes or ignored/untracked directories).
- *
- * Under some circumstances, in the name of efficiency, not all fields will
- * be filled in, but we generally try to fill in as much as possible.  One
- * example is that the "flags" field may not have either the `BINARY` or the
- * `NOT_BINARY` flag set to avoid examining file contents if you do not pass
- * in hunk and/or line callbacks to the diff foreach iteration function.  It
- * will just use the git attributes for those files.
- *
- * The similarity score is zero unless you call `git_diff_find_similar()`
- * which does a similarity analysis of files in the diff.  Use that
- * function to do rename and copy detection, and to split heavily modified
- * files in add/delete pairs.  After that call, deltas with a status of
- * GIT_DELTA_RENAMED or GIT_DELTA_COPIED will have a similarity score
- * between 0 and 100 indicating how similar the old and new sides are.
- *
- * If you ask `git_diff_find_similar` to find heavily modified files to
- * break, but to not *actually* break the records, then GIT_DELTA_MODIFIED
- * records may have a non-zero similarity score if the self-similarity is
- * below the split threshold.  To display this value like core Git, invert
- * the score (a la `printf("M%03d", 100 - delta->similarity)`).

-/**
- * @file git2/pack.h
- * @brief Git pack management routines
- *
- * Packing objects
- * ---------------
- *
- * Creation of packfiles requires two steps:
- *
- * - First, insert all the objects you want to put into the packfile
- *   using `git_packbuilder_insert` and `git_packbuilder_insert_tree`.
- *   It's important to add the objects in recency order ("in the order
- *   that they are 'reachable' from head").
- *
- *   "ANY order will give you a working pack, ... [but it is] the thing
- *   that gives packs good locality. It keeps the objects close to the
- *   head (whether they are old or new, but they are _reachable_ from the
- *   head) at the head of the pack. So packs actually have absolutely
- *   _wonderful_ IO patterns." - Linus Torvalds
- *   git.git/Documentation/technical/pack-heuristics.txt
- *
- * - Second, use `git_packbuilder_write` or `git_packbuilder_foreach` to
- *   write the resulting packfile.
- *
- *   libgit2 will take care of the delta ordering and generation.
- *   `git_packbuilder_set_threads` can be used to adjust the number of
- *   threads used for the process.
- *
- * See tests/pack/packbuilder.c for an example.

-# API Documentation Generator
-
-These scripts generate the "raw API" specs and reference documentation
-for [www.libgit2.org](https://libgit2.org/docs/reference).
-
-The "raw API" specs consists of JSON documents, on per
-released version or branch, that describes the APIs. This is
-suitable for creating documentation from, or may be useful for
-language bindings as well.
-
-The reference documentation is documentation fragments for each
-API in each version, ready to be included in the libgit2 documentation
-website.

-# cli
-
-A git-compatible command-line interface that uses libgit2.
-
-## Adding commands
-
-1. Individual commands have a `main`-like top-level entrypoint.  For example:
-
-   ```c
-   int cmd_help(int argc, char **argv)
-   ```
-
-   Although this is the same signature as `main`, commands are not built as
-   individual standalone executables, they'll be linked into the main cli.
-   (Though there may be an option for command executables to be built as
-   standalone executables in the future.)
-
-2. Commands are prototyped in `cmd.h` and added to `main.c`'s list of
-   commands (`cli_cmds[]`).  Commands should be specified with their name,
-   entrypoint and a brief description that can be printed in `git help`.
-   This is done because commands are linked into the main cli.
-
-3. Commands should accept a `--help` option that displays their help
-   information.  This will be shown when a user runs `<command> --help` and
-   when a user runs `help <command>`.

- *
- * - An optional prefix ! which negates the pattern; any matching file

- *
- * - If the pattern ends with a slash, it is removed for the purpose of the

- *
- * - Otherwise, git treats the pattern as a shell glob suitable for consumption

-/**
- * The wonderful tale of a Packed Object lookup query
- * ===================================================
- *	A riveting and epic story of epicness and ASCII
- *			art, presented by yours truly,
- *				Sir Vicent of Marti
- *
- *
- *	Chapter 1: Once upon a time...
- *	Initialization of the Pack Backend
- *	--------------------------------------------------
- *
- * # git_odb_backend_pack
- * | Creates the pack backend structure, initializes the
- * | callback pointers to our default read() and exist() methods,
- * | and tries to find the `pack` folder, if it exists. ODBs without a `pack`
- * | folder are ignored altogether. If there is a `pack` folder, it tries to
- * | preload all the known packfiles in the ODB.
- * |
- * |-# pack_backend__refresh
- *   | The `multi-pack-index` is loaded if it exists and is valid.
- *   | Then we run a `dirent` callback through every file in the pack folder,
- *   | even those present in `multi-pack-index`. The unindexed packfiles are
- *   | then sorted according to a sorting callback.
- *   |
- *   |-# refresh_multi_pack_index
- *   |   Detect the presence of the `multi-pack-index` file. If it needs to be
- *   |   refreshed, frees the old copy and tries to load the new one, together
- *   |   with all the packfiles it indexes. If the process fails, fall back to
- *   |   the old behavior, as if the `multi-pack-index` file was not there.
- *   |
- *   |-# packfile_load__cb
- *   | | This callback is called from `dirent` with every single file
- *   | | inside the pack folder. We find the packs by actually locating
- *   | | their index (ends in ".idx"). From that index, we verify that
- *   | | the corresponding packfile exists and is valid, and if so, we
- *   | | add it to the pack list.
- *   | |
- *   | # git_mwindow_get_pack
- *   |   Make sure that there's a packfile to back this index, and store
- *   |   some very basic information regarding the packfile itself,
- *   |   such as the full path, the size, and the modification time.
- *   |   We don't actually open the packfile to check for internal consistency.
- *   |
- *   |-# packfile_sort__cb
- *       Sort all the preloaded packs according to some specific criteria:
- *       we prioritize the "newer" packs because it's more likely they
- *       contain the objects we are looking for, and we prioritize local
- *       packs over remote ones.
- *
- *
- *
- *	Chapter 2: To be, or not to be...
- *	A standard packed `exist` query for an OID
- *	--------------------------------------------------
- *
- * # pack_backend__exists / pack_backend__exists_prefix
- * | Check if the given oid (or an oid prefix) exists in any of the
- * | packs that have been loaded for our ODB.
- * |
- * |-# pack_entry_find / pack_entry_find_prefix
- *   | If there is a multi-pack-index present, search the oid in that
- *   | index first. If it is not found there, iterate through all the unindexed
- *   | packs that have been preloaded (starting by the pack where the latest
- *   | object was found) to try to find the OID in one of them.
- *   |
- *   |-# git_midx_entry_find
- *   |   Search for the oid in the multi-pack-index. See
- *   |   <https://github.com/git/git/blob/master/Documentation/technical/pack-format.txt>
- *   |   for specifics on the multi-pack-index format and how do we find
- *   |   entries in it.
- *   |
- *   |-# git_pack_entry_find
- *     | Check the index of an individual unindexed pack to see if the
- *     | OID can be found. If we can find the offset to that inside of the
- *     | index, that means the object is contained inside of the packfile and
- *     | we can stop searching. Before returning, we verify that the
- *     | packfile behind the index we are searching still exists on disk.
- *     |
- *     |-# pack_entry_find_offset
- *       | Mmap the actual index file to disk if it hasn't been opened
- *       | yet, and run a binary search through it to find the OID.
- *       | See <https://github.com/git/git/blob/master/Documentation/technical/pack-format.txt>
- *       | for specifics on the Packfile Index format and how do we find
- *       | entries in it.
- *       |
- *       |-# pack_index_open
- *         | Guess the name of the index based on the full path to the
- *         | packfile, open it and verify its contents. Only if the index
- *         | has not been opened already.
- *         |
- *         |-# pack_index_check
- *             Mmap the index file and do a quick run through the header
- *             to guess the index version (right now we support v1 and v2),
- *             and to verify that the size of the index makes sense.
- *
- *
- *
- *	Chapter 3: The neverending story...
- *	A standard packed `lookup` query for an OID
- *	--------------------------------------------------
- *
- * # pack_backend__read / pack_backend__read_prefix
- * | Check if the given oid (or an oid prefix) exists in any of the
- * | packs that have been loaded for our ODB. If it does, open the packfile and
- * | read from it.
- * |
- * |-# git_packfile_unpack
- *     Armed with a packfile and the offset within it, we can finally unpack
- *     the object pointed at by the oid. This involves mmapping part of
- *     the `.pack` file, and uncompressing the object within it (if it is
- *     stored in the undelfitied representation), or finding a base object and
- *     applying some deltas to its uncompressed representation (if it is stored
- *     in the deltified representation). See
- *     <https://github.com/git/git/blob/master/Documentation/technical/pack-format.txt>
- *     for specifics on the Packfile format and how do we read from it.

-/*
- * What wizardry is this?
- *
- * This is just a memory-optimized trie: basically a very fancy
- * 16-ary tree, which is used to store the prefixes of the OID
- * strings.
- *
- * Read more: http://en.wikipedia.org/wiki/Trie
- *
- * Magic that happens in this method:
- *
- *	- Each node in the trie is an union, so it can work both as
- *	a normal node, or as a leaf.
- *
- *	- Each normal node points to 16 children (one for each possible
- *	character in the oid). This is *not* stored in an array of
- *	pointers, because in a 64-bit arch this would be sucking
- *	16*sizeof(void*) = 128 bytes of memory per node, which is
- *	insane. What we do is store Node Indexes, and use these indexes
- *	to look up each node in the om->index array. These indexes are
- *	signed shorts, so this limits the amount of unique OIDs that
- *	fit in the structure to about 20000 (assuming a more or less uniform
- *	distribution).
- *
- *	- All the nodes in om->index array are stored contiguously in
- *	memory, and each of them is 32 bytes, so we fit 2x nodes per
- *	cache line. Convenient for speed.
- *
- *	- To differentiate the leafs from the normal nodes, we store all
- *	the indexes towards a leaf as a negative index (indexes to normal
- *	nodes are positives). When we find that one of the children for
- *	a node has a negative value, that means it's going to be a leaf.
- *	This reduces the amount of indexes we have by two, but also reduces
- *	the size of each node by 1-4 bytes (the amount we would need to
- *	add a `is_leaf` field): this is good because it allows the nodes
- *	to fit cleanly in cache lines.
- *
- *	- Once we reach an empty children, instead of continuing to insert
- *	new nodes for each remaining character of the OID, we store a pointer
- *	to the tail in the leaf; if the leaf is reached again, we turn it
- *	into a normal node and use the tail to create a new leaf.
- *
- *	This is a pretty good balance between performance and memory usage.

-/**
- * Description of submodule
- *
- * This record describes a submodule found in a repository.  There should be
- * an entry for every submodule found in the HEAD and index, and for every
- * submodule described in .gitmodules.  The fields are as follows:
- *
- * - `rc` tracks the refcount of how many hash table entries in the
- *   git_submodule_cache there are for this submodule.  It only comes into
- *   play if the name and path of the submodule differ.
- *
- * - `name` is the name of the submodule from .gitmodules.
- * - `path` is the path to the submodule from the repo root.  It is almost
- *    always the same as `name`.
- * - `url` is the url for the submodule.
- * - `update` is a git_submodule_update_t value - see gitmodules(5) update.
- * - `update_default` is the update value from the config
- * - `ignore` is a git_submodule_ignore_t value - see gitmodules(5) ignore.
- * - `ignore_default` is the ignore value from the config
- * - `fetch_recurse` is a git_submodule_recurse_t value - see gitmodules(5)
- *    fetchRecurseSubmodules.
- * - `fetch_recurse_default` is the recurse value from the config
- *
- * - `repo` is the parent repository that contains this submodule.
- * - `flags` after for internal use, tracking where this submodule has been
- *   found (head, index, config, workdir) and known status info, etc.
- * - `head_oid` is the oid for the submodule path in the repo HEAD.
- * - `index_oid` is the oid for the submodule recorded in the index.
- * - `wd_oid` is the oid for the HEAD of the checked out submodule.
- *
- * If the submodule has been added to .gitmodules but not yet git added,
- * then the `index_oid` will be zero but still marked valid.  If the
- * submodule has been deleted, but the delete has not been committed yet,
- * then the `index_oid` will be set, but the `url` will be NULL.

- *      This file implements the Secure Hash Algorithms
- *      as defined in the U.S. National Institute of Standards
- *      and Technology Federal Information Processing Standards
- *      Publication (FIPS PUB) 180-3 published in October 2008
- *      and formerly defined in its predecessors, FIPS PUB 180-1
- *      and FIP PUB 180-2.

- *
- *      The five hashes are defined in these sizes:
- *              SHA-1           20 byte / 160 bit
- *              SHA-224         28 byte / 224 bit
- *              SHA-256         32 byte / 256 bit
- *              SHA-384         48 byte / 384 bit
- *              SHA-512         64 byte / 512 bit
- *
- *  Compilation Note:
- *    These files may be compiled with two options:
- *        USE_32BIT_ONLY - use 32-bit arithmetic only, for systems
- *                         without 64-bit integers
- *
- *        USE_MODIFIED_MACROS - use alternate form of the SHA_Ch()
- *                         and SHA_Maj() macros that are equivalent

- * Description:
- *   This file implements the Secure Hash Algorithms SHA-224 and
- *   SHA-256 as defined in the U.S. National Institute of Standards
- *   and Technology Federal Information Processing Standards
- *   Publication (FIPS PUB) 180-3 published in October 2008
- *   and formerly defined in its predecessors, FIPS PUB 180-1
- *   and FIP PUB 180-2.

- *              fips180-3/fips180-3_final.pdf
- *
- *   The SHA-224 and SHA-256 algorithms produce 224-bit and 256-bit
- *   message digests for a given data stream.  It should take about
- *   2**n steps to find a message with the same digest as a given
- *   message and 2**(n/2) to find any two messages with the same
- *   digest, when n is the digest size in bits.  Therefore, this
- *   algorithm can serve as a means of providing a
- *   "fingerprint" for a message.
- *
- * Portability Issues:
- *   SHA-224 and SHA-256 are defined in terms of 32-bit "words".
- *   This code uses <stdint.h> (included via "sha.h") to define 32-
- *   and 8-bit unsigned integer types.  If your C compiler does not
- *   support 32-bit unsigned integers, this code is not
- *   appropriate.
- *
- * Caveats:
- *   SHA-224 and SHA-256 are designed to work with messages less
- *   than 2^64 bits long.  This implementation uses SHA224/256Input()
- *   to hash the bits that are a multiple of the size of an 8-bit
- *   octet, and then optionally uses SHA224/256FinalBits()
- *   to hash the final few bits of the input.

-        thus for 240-steps an immediate lower-bound for the best cryptanalytic attacks would be 2^180.
-        An attacker would be better off using a generic birthday search of complexity 2^80.
-
-   Enabling safe SHA-1 hashing will result in the correct SHA-1 hash for messages where no collision attack was detected,
-   but it will result in a different SHA-1 hash for messages where a collision attack was detected.
-   This will automatically invalidate SHA-1 based digital signature forgeries.
-   Enabled by default.

-//
-// sha1_dvs contains a list of SHA-1 Disturbance Vectors (DV) to check
-// dvType, dvK and dvB define the DV: I(K,B) or II(K,B) (see the paper)
-// dm[80] is the expanded message block XOR-difference defined by the DV
-// testt is the step to do the recompression from for collision detection
-// maski and maskb define the bit to check for each DV in the dvmask returned by ubc_check
-//
-// ubc_check takes as input an expanded message block and verifies the unavoidable bitconditions for all listed DVs
-// it returns a dvmask where each bit belonging to a DV is set if all unavoidable bitconditions for that DV have been met
-// thus one needs to do the recompression check for each DV that has its bit set
-//
-// ubc_check is programmatically generated and the unavoidable bitconditions have been hardcoded
-// a directly verifiable version named ubc_check_verify can be found in ubc_check_verify.c
-// ubc_check has been verified against ubc_check_verify using the 'ubc_check_test' program in the tools section
