+Authors of XZ Utils
+===================
+
+    XZ Utils is developed and maintained by Lasse Collin
+    <[email protected]>.
+
+    Major parts of liblzma are based on code written by Igor Pavlov,
+    specifically the LZMA SDK <http://7-zip.org/sdk.html>. Without
+    this code, XZ Utils wouldn't exist.
+
+    The SHA-256 implementation in liblzma is based on the code found from
+    7-Zip <http://7-zip.org/>, which has a modified version of the SHA-256
+    code found from Crypto++ <http://www.cryptopp.com/>. The SHA-256 code
+    in Crypto++ was written by Kevin Springle and Wei Dai.
+
+    Some scripts have been adapted from gzip. The original versions
+    were written by Jean-loup Gailly, Charles Levert, and Paul Eggert.
+    Andrew Dudman helped adapting the scripts and their man pages for
+    XZ Utils.
+
+    The GNU Autotools-based build system contains files from many authors,
+    which I'm not trying to list here.
+
+    Several people have contributed fixes or reported bugs. Most of them
+    are mentioned in the file THANKS.

+#############################################################################
+#
+# Very limited CMake support for building some parts of XZ Utils
+#
+# For now, this is indented to be useful to build static or shared liblzma
+# on Windows with MSVC (to avoid the need to maintain Visual Studio project
+# files). Building liblzma on a few other platforms should work too but it
+# is somewhat experimental and not as portable as using ./configure.
+#
+# On some platforms this builds also xz and xzdec, but these are
+# highly experimental and meant for testing only:
+#   - No large file support on those 32-bit platforms that need it
+#   - No replacement getopt_long(), libc must have it
+#   - No sandboxing support
+#   - No translations
+#   - No xz symlinks are installed
+#
+# Other missing things:
+#   - No xzgrep or other scripts or their symlinks
+#   - No tests (no test failures either!)
+#
+# NOTE: Even if the code compiles without warnings, the end result may be
+# different than via ./configure. Specifically, the list of #defines
+# may be different (if so, probably this CMakeLists.txt got them wrong).
+#
+# This file provides the following installation components (if you only
+# need liblzma, install only its components!):
+#   - liblzma_Runtime
+#   - liblzma_Development
+#   - xz (on some platforms only)
+#   - xzdec (on some platforms only)
+#
+# To find the target liblzma::liblzma from other packages, use the CONFIG
+# option with find_package() to avoid a conflict with the FindLibLZMA module
+# with case-insensitive file systems. For example, to require liblzma 5.2.5
+# or a newer compatible version:
+#
+#     find_package(liblzma 5.2.5 REQUIRED CONFIG)
+#     target_link_libraries(my_application liblzma::liblzma)

+XZ Utils Licensing
+==================
+
+    Different licenses apply to different files in this package. Here
+    is a rough summary of which licenses apply to which parts of this
+    package (but check the individual files to be sure!):
+
+      - liblzma is in the public domain.
+
+      - xz, xzdec, and lzmadec command line tools are in the public
+        domain unless GNU getopt_long had to be compiled and linked
+        in from the lib directory. The getopt_long code is under
+        GNU LGPLv2.1+.
+
+      - The scripts to grep, diff, and view compressed files have been
+        adapted from gzip. These scripts and their documentation are
+        under GNU GPLv2+.
+
+      - All the documentation in the doc directory and most of the
+        XZ Utils specific documentation files in other directories
+        are in the public domain.
+
+      - Translated messages are in the public domain.
+
+      - The build system contains public domain files, and files that
+        are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
+        in the binaries being built.
+
+      - Test files and test code in the tests directory, and debugging
+        utilities in the debug directory are in the public domain.
+
+      - The extra directory may contain public domain files, and files
+        that are under various free software licenses.
+
+    You can do whatever you want with the files that have been put into
+    the public domain. If you find public domain legally problematic,
+    take the previous sentence as a license grant. If you still find
+    the lack of copyright legally problematic, you have too many
+    lawyers.
+
+    As usual, this software is provided "as is", without any warranty.
+
+    If you copy significant amounts of public domain code from XZ Utils
+    into your project, acknowledging this somewhere in your software is
+    polite (especially if it is proprietary, non-free software), but
+    naturally it is not legally required. Here is an example of a good
+    notice to put into "about box" or into documentation:
+
+        This software includes code from XZ Utils <https://tukaani.org/xz/>.
+
+    The following license texts are included in the following files:
+      - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
+      - COPYING.GPLv2: GNU General Public License version 2
+      - COPYING.GPLv3: GNU General Public License version 3
+
+    Note that the toolchain (compiler, linker etc.) may add some code
+    pieces that are copyrighted. Thus, it is possible that e.g. liblzma
+    binary wouldn't actually be in the public domain in its entirety
+    even though it contains no copyrighted code from the XZ Utils source
+    package.
+
+    If you have questions, don't hesitate to ask the author(s) for more
+    information.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 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.
+
+                            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 Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+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.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser General
+Public License instead of this License.

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

+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <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 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.

+                       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

+    C99 features used in XZ Utils source code, thus GCC 2 won't compile
+    XZ Utils.
+
+    XZ Utils takes advantage of some GNU C extensions when building
+    with GCC. Because these extensions are used only when building
+    with GCC, it should be possible to use any C99 compiler.
+
+
+1.2. Platform-specific notes
+
+1.2.1. AIX
+
+    If you use IBM XL C compiler, pass CC=xlc_r to configure. If
+    you use CC=xlc instead, you must disable threading support
+    with --disable-threads (usually not recommended).
+
+
+1.2.2. IRIX
+
+    MIPSpro 7.4.4m has been reported to produce broken code if using
+    the -O2 optimization flag ("make check" fails). Using -O1 should
+    work.
+
+    A problem has been reported when using shared liblzma. Passing
+    --disable-shared to configure works around this. Alternatively,
+    putting "-64" to CFLAGS to build a 64-bit version might help too.
+
+
+1.2.3. MINIX 3
+
+    The default install of MINIX 3 includes Amsterdam Compiler Kit (ACK),
+    which doesn't support C99. Install GCC to compile XZ Utils.
+
+    MINIX 3.1.8 and older have bugs in /usr/include/stdint.h, which has
+    to be patched before XZ Utils can be compiled correctly. See
+    <http://gforge.cs.vu.nl/gf/project/minix/tracker/?action=TrackerItemEdit&tracker_item_id=537>.
+
+    MINIX 3.2.0 and later use a different libc and aren't affected by
+    the above bug.
+
+    XZ Utils doesn't have code to detect the amount of physical RAM and
+    number of CPU cores on MINIX 3.
+
+    See section 4.4 in this file about symbol visibility warnings (you
+    may want to pass gl_cv_cc_visibility=no to configure).
+
+
+1.2.4. OpenVMS
+
+    XZ Utils can be built for OpenVMS, but the build system files
+    are not included in the XZ Utils source package. The required
+    OpenVMS-specific files are maintained by Jouk Jansen and can be
+    downloaded here:
+
+        http://nchrem.tnw.tudelft.nl/openvms/software2.html#xzutils
+
+
+1.2.5. Solaris, OpenSolaris, and derivatives
+
+    The following linker error has been reported on some x86 systems:
+
+        ld: fatal: relocation error: R_386_GOTOFF: ...
+
+    This can be worked around by passing gl_cv_cc_visibility=no
+    as an argument to the configure script.
+
+    test_scripts.sh in "make check" may fail if good enough tools are
+    missing from PATH (/usr/xpg4/bin or /usr/xpg6/bin). Nowadays
+    /usr/xpg4/bin is added to the script PATH by default on Solaris
+    (see --enable-path-for-scripts=PREFIX in section 2), but old xz
+    releases needed extra steps. See sections 4.5 and 3.2 for more
+    information.
+
+
+1.2.6. Tru64
+
+    If you try to use the native C compiler on Tru64 (passing CC=cc to
+    configure), you may need the workaround mention in section 4.1 in
+    this file (pass also ac_cv_prog_cc_c99= to configure).
+
+
+1.2.7. Windows
+
+    If it is enough to build liblzma (no command line tools):
+
+      - There is experimental CMake support. As it is, it should be
+        good enough to build static liblzma with Visual Studio.
+        Building liblzma.dll might work too (if it doesn't, it should
+        be fixed). The CMake support may work with MinGW or MinGW-w64.
+        Read the comment in the beginning of CMakeLists.txt before
+        running CMake!
+
+      - There are Visual Studio project files under the "windows"
+        directory. See windows/INSTALL-MSVC.txt. In the future the
+        project files will be removed when CMake support is good
+        enough. Thus, please test the CMake version and help fix
+        possible issues.
+
+    To build also the command line tools:
+
+      - MinGW-w64 + MSYS (32-bit and 64-bit x86): This is used
+        for building the official binary packages for Windows.
+        There is windows/build.bash to ease packaging XZ Utils with
+        MinGW(-w64) + MSYS into a redistributable .zip or .7z file.
+        See windows/INSTALL-MinGW.txt for more information.
+
+      - MinGW + MSYS (32-bit x86): I haven't recently tested this.
+
+      - Cygwin 1.7.35 and later: NOTE that using XZ Utils >= 5.2.0
+        under Cygwin older than 1.7.35 can lead to DATA LOSS! If
+        you must use an old Cygwin version, stick to XZ Utils 5.0.x
+        which is safe under older Cygwin versions. You can check
+        the Cygwin version with the command "cygcheck -V".
+
+    It may be possible to build liblzma with other toolchains too, but
+    that will probably require writing a separate makefile. Building
+    the command line tools with non-GNU toolchains will be harder than
+    building only liblzma.
+
+    Even if liblzma is built with MinGW(-w64), the resulting DLL can
+    be used by other compilers and linkers, including MSVC. See
+    windows/README-Windows.txt for details.
+
+
+1.2.8. DOS
+
+    There is a Makefile in the "dos" directory to build XZ Utils on
+    DOS using DJGPP. Support for long file names (LFN) is needed at
+    build time but the resulting xz.exe works without LFN support too.
+    See dos/INSTALL.txt and dos/README.txt for more information.
+
+
+1.2.9. z/OS
+
+    To build XZ Utils on z/OS UNIX System Services using xlc, pass
+    these options to the configure script: CC='xlc -qhaltonmsg=CCN3296'
+    CPPFLAS='-D_UNIX03_THREADS -D_XOPEN_SOURCE=600'. The first makes
+    xlc throw an error if a header file is missing, which is required
+    to make the tests in configure work. The CPPFLAGS are needed to
+    get pthread support (some other CPPFLAGS may work too; if there
+    are problems, try -D_UNIX95_THREADS instead of -D_UNIX03_THREADS).
+
+    test_scripts.sh in "make check" will fail even if the scripts
+    actually work because the test data includes compressed files
+    with US-ASCII text.
+
+    No other tests should fail. If test_files.sh fails, check that
+    the included .xz test files weren't affected by EBCDIC conversion.
+
+    XZ Utils doesn't have code to detect the amount of physical RAM and
+    number of CPU cores on z/OS.
+
+
+1.3. Adding support for new platforms
+
+    If you have written patches to make XZ Utils to work on previously
+    unsupported platform, please send the patches to me! I will consider
+    including them to the official version. It's nice to minimize the
+    need of third-party patching.
+
+    One exception: Don't request or send patches to change the whole
+    source package to C89. I find C99 substantially nicer to write and
+    maintain. However, the public library headers must be in C89 to
+    avoid frustrating those who maintain programs, which are strictly
+    in C89 or C++.
+
+
+2. configure options
+--------------------
+
+    In most cases, the defaults are what you want. Many of the options
+    below are useful only when building a size-optimized version of
+    liblzma or command line tools.
+
+    --enable-encoders=LIST
+    --disable-encoders
+                Specify a comma-separated LIST of filter encoders to
+                build. See "./configure --help" for exact list of
+                available filter encoders. The default is to build all
+                supported encoders.
+
+                If LIST is empty or --disable-encoders is used, no filter
+                encoders will be built and also the code shared between
+                encoders will be omitted.
+
+                Disabling encoders will remove some symbols from the
+                liblzma ABI, so this option should be used only when it
+                is known to not cause problems.
+
+    --enable-decoders=LIST
+    --disable-decoders
+                This is like --enable-encoders but for decoders. The
+                default is to build all supported decoders.
+
+    --enable-match-finders=LIST
+                liblzma includes two categories of match finders:
+                hash chains and binary trees. Hash chains (hc3 and hc4)
+                are quite fast but they don't provide the best compression
+                ratio. Binary trees (bt2, bt3 and bt4) give excellent
+                compression ratio, but they are slower and need more
+                memory than hash chains.
+
+                You need to enable at least one match finder to build the
+                LZMA1 or LZMA2 filter encoders. Usually hash chains are
+                used only in the fast mode, while binary trees are used to
+                when the best compression ratio is wanted.
+
+                The default is to build all the match finders if LZMA1
+                or LZMA2 filter encoders are being built.
+
+    --enable-checks=LIST
+                liblzma support multiple integrity checks. CRC32 is
+                mandatory, and cannot be omitted. See "./configure --help"
+                for exact list of available integrity check types.
+
+                liblzma and the command line tools can decompress files
+                which use unsupported integrity check type, but naturally
+                the file integrity cannot be verified in that case.
+
+                Disabling integrity checks may remove some symbols from
+                the liblzma ABI, so this option should be used only when
+                it is known to not cause problems.
+
+    --enable-external-sha256
+                Try to use SHA-256 code from the operating system libc
+                or similar base system libraries. This doesn't try to
+                use OpenSSL or libgcrypt or such libraries.
+
+                The reasons to use this option:
+
+                  - It makes liblzma slightly smaller.
+
+                  - It might improve SHA-256 speed if the implementation
+                    in the operating is very good (but see below).
+
+                External SHA-256 is disabled by default for two reasons:
+
+                  - On some operating systems the symbol names of the
+                    SHA-256 functions conflict with OpenSSL's libcrypto.
+                    This causes weird problems such as decompression
+                    errors if an application is linked against both
+                    liblzma and libcrypto. This problem affects at least
+                    FreeBSD 10 and older and MINIX 3.3.0 and older, but
+                    other OSes that provide a function "SHA256_Init" might
+                    also be affected. FreeBSD 11 has the problem fixed.
+                    NetBSD had the problem but it was fixed it in 2009
+                    already. OpenBSD uses "SHA256Init" and thus never had
+                    a conflict with libcrypto.
+
+                  - The SHA-256 code in liblzma is faster than the SHA-256
+                    code provided by some operating systems. If you are
+                    curious, build two copies of xz (internal and external
+                    SHA-256) and compare the decompression (xz --test)
+                    times:
+
+                        dd if=/dev/zero bs=1024k count=1024 \
+                            | xz -v -0 -Csha256 > foo.xz
+                        time xz --test foo.xz
+
+    --disable-xz
+    --disable-xzdec
+    --disable-lzmadec
+    --disable-lzmainfo
+                Don't build and install the command line tool mentioned
+                in the option name.
+
+                NOTE: Disabling xz will skip some tests in "make check".
+
+                NOTE: If xzdec is disabled and lzmadec is left enabled,
+                a dangling man page symlink lzmadec.1 -> xzdec.1 is
+                created.
+
+    --disable-lzma-links
+                Don't create symlinks for LZMA Utils compatibility.
+                This includes lzma, unlzma, and lzcat. If scripts are
+                installed, also lzdiff, lzcmp, lzgrep, lzegrep, lzfgrep,
+                lzmore, and lzless will be omitted if this option is used.
+
+    --disable-scripts
+                Don't install the scripts xzdiff, xzgrep, xzmore, xzless,
+                and their symlinks.
+
+    --disable-doc
+                Don't install the documentation files to $docdir
+                (often /usr/doc/xz or /usr/local/doc/xz). Man pages
+                will still be installed. The $docdir can be changed
+                with --docdir=DIR.
+
+    --disable-assembler
+                liblzma includes some assembler optimizations. Currently
+                there is only assembler code for CRC32 and CRC64 for
+                32-bit x86.
+
+                All the assembler code in liblzma is position-independent
+                code, which is suitable for use in shared libraries and
+                position-independent executables. So far only i386
+                instructions are used, but the code is optimized for i686
+                class CPUs. If you are compiling liblzma exclusively for
+                pre-i686 systems, you may want to disable the assembler
+                code.
+
+    --enable-unaligned-access
+                Allow liblzma to use unaligned memory access for 16-bit
+                and 32-bit loads and stores. This should be enabled only
+                when the hardware supports this, i.e. when unaligned
+                access is fast. Some operating system kernels emulate
+                unaligned access, which is extremely slow. This option
+                shouldn't be used on systems that rely on such emulation.
+
+                Unaligned access is enabled by default on x86, x86-64,
+                and big endian PowerPC.
+
+    --enable-small
+                Reduce the size of liblzma by selecting smaller but
+                semantically equivalent version of some functions, and
+                omit precomputed lookup tables. This option tends to
+                make liblzma slightly slower.
+
+                Note that while omitting the precomputed tables makes
+                liblzma smaller on disk, the tables are still needed at
+                run time, and need to be computed at startup. This also
+                means that the RAM holding the tables won't be shared
+                between applications linked against shared liblzma.
+
+                This option doesn't modify CFLAGS to tell the compiler
+                to optimize for size. You need to add -Os or equivalent
+                flag(s) to CFLAGS manually.
+
+    --enable-assume-ram=SIZE
+                On the most common operating systems, XZ Utils is able to
+                detect the amount of physical memory on the system. This
+                information is used by the options --memlimit-compress,
+                --memlimit-decompress, and --memlimit when setting the
+                limit to a percentage of total RAM.
+
+                On some systems, there is no code to detect the amount of
+                RAM though. Using --enable-assume-ram one can set how much
+                memory to assume on these systems. SIZE is given as MiB.
+                The default is 128 MiB.
+
+                Feel free to send patches to add support for detecting
+                the amount of RAM on the operating system you use. See
+                src/common/tuklib_physmem.c for details.
+
+    --enable-threads=METHOD
+                Threading support is enabled by default so normally there
+                is no need to specify this option.
+
+                Supported values for METHOD:
+
+                        yes     Autodetect the threading method. If none
+                                is found, configure will give an error.
+
+                        posix   Use POSIX pthreads. This is the default
+                                except on Windows outside Cygwin.
+
+                        win95   Use Windows 95 compatible threads. This
+                                is compatible with Windows XP and later
+                                too. This is the default for 32-bit x86
+                                Windows builds. The `win95' threading is
+                                incompatible with --enable-small.
+
+                        vista   Use Windows Vista compatible threads. The
+                                resulting binaries won't run on Windows XP
+                                or older. This is the default for Windows
+                                excluding 32-bit x86 builds (that is, on
+                                x86-64 the default is `vista').
+
+                        no      Disable threading support. This is the
+                                same as using --disable-threads.
+                                NOTE: If combined with --enable-small, the
+                                resulting liblzma won't be thread safe,
+                                that is, if a multi-threaded application
+                                calls any liblzma functions from more than
+                                one thread, something bad may happen.
+
+    --enable-sandbox=METHOD
+                There is limited sandboxing support in the xz tool. If
+                built with sandbox support, it's used automatically when
+                (de)compressing exactly one file to standard output and
+                the options --files or --files0 weren't used. This is a
+                common use case, for example, (de)compressing .tar.xz
+                files via GNU tar. The sandbox is also used for
+                single-file `xz --test' or `xz --list'.
+
+                Supported METHODs:
+
+                        auto    Look for a supported sandboxing method
+                                and use it if found. If no method is
+                                found, then sandboxing isn't used.
+                                This is the default.
+
+                        no      Disable sandboxing support.
+
+                        capsicum
+                                Use Capsicum (FreeBSD >= 10) for
+                                sandboxing. If no Capsicum support
+                                is found, configure will give an error.
+
+    --enable-symbol-versions
+                Use symbol versioning for liblzma. This is enabled by
+                default on GNU/Linux, other GNU-based systems, and
+                FreeBSD.
+
+    --enable-debug
+                This enables the assert() macro and possibly some other
+                run-time consistency checks. It makes the code slower, so
+                you normally don't want to have this enabled.
+
+    --enable-werror
+                If building with GCC, make all compiler warnings an error,
+                that abort the compilation. This may help catching bugs,
+                and should work on most systems. This has no effect on the
+                resulting binaries.
+
+    --enable-path-for-scripts=PREFIX
+                If PREFIX isn't empty, PATH=PREFIX:$PATH will be set in
+                the beginning of the scripts (xzgrep and others).
+                The default is empty except on Solaris the default is
+                /usr/xpg4/bin.
+
+                This can be useful if the default PATH doesn't contain
+                modern POSIX tools (as can be the case on Solaris) or if
+                one wants to ensure that the correct xz binary is in the
+                PATH for the scripts. Note that the latter use can break
+                "make check" if the prefixed PATH causes a wrong xz binary
+                (other than the one that was just built) to be used.
+
+                Older xz releases support a different method for setting
+                the PATH for the scripts. It is described in section 3.2
+                and is supported in this xz version too.
+
+
+2.1. Static vs. dynamic linking of liblzma
+
+    On 32-bit x86, linking against static liblzma can give a minor
+    speed improvement. Static libraries on x86 are usually compiled as
+    position-dependent code (non-PIC) and shared libraries are built as
+    position-independent code (PIC). PIC wastes one register, which can
+    make the code slightly slower compared to a non-PIC version. (Note
+    that this doesn't apply to x86-64.)
+
+    If you want to link xz against static liblzma, the simplest way
+    is to pass --disable-shared to configure. If you want also shared
+    liblzma, run configure again and run "make install" only for
+    src/liblzma.
+
+
+2.2. Optimizing xzdec and lzmadec
+
+    xzdec and lzmadec are intended to be relatively small instead of
+    optimizing for the best speed. Thus, it is a good idea to build
+    xzdec and lzmadec separately:
+
+      - To link the tools against static liblzma, pass --disable-shared
+        to configure.
+
+      - To select somewhat size-optimized variant of some things in
+        liblzma, pass --enable-small to configure.
+
+      - Tell the compiler to optimize for size instead of speed.
+        E.g. with GCC, put -Os into CFLAGS.
+
+      - xzdec and lzmadec will never use multithreading capabilities of
+        liblzma. You can avoid dependency on libpthread by passing
+        --disable-threads to configure.
+
+      - There are and will be no translated messages for xzdec and
+        lzmadec, so it is fine to pass also --disable-nls to configure.
+
+      - Only decoder code is needed, so you can speed up the build
+        slightly by passing --disable-encoders to configure. This
+        shouldn't affect the final size of the executables though,
+        because the linker is able to omit the encoder code anyway.
+
+    If you have no use for xzdec or lzmadec, you can disable them with
+    --disable-xzdec and --disable-lzmadec.
+
+
+3. xzgrep and other scripts
+---------------------------
+
+3.1. Dependencies
+
+    POSIX shell (sh) and bunch of other standard POSIX tools are required
+    to run the scripts. The configure script tries to find a POSIX
+    compliant sh, but if it fails, you can force the shell by passing
+    gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
+    script.
+
+    xzdiff (xzcmp/lzdiff/lzcmp) may use mktemp if it is available. As
+    a fallback xzdiff will use mkdir to securely create a temporary
+    directory. Having mktemp available is still recommended since the
+    mkdir fallback method isn't as robust as mktemp is. The original
+    mktemp can be found from <http://www.mktemp.org/>. On GNU, most will
+    use the mktemp program from GNU coreutils instead of the original
+    implementation. Both mktemp versions are fine.
+
+    In addition to using xz to decompress .xz files, xzgrep and xzdiff
+    use gzip, bzip2, and lzop to support .gz, bz2, and .lzo files.
+
+
+3.2. PATH
+
+    The method described below is supported by older xz releases.
+    It is supported by the current version too, but the newer
+    --enable-path-for-scripts=PREFIX described in section 2 may be
+    more convenient.
+
+    The scripts assume that the required tools (standard POSIX utilities,
+    mktemp, and xz) are in PATH; the scripts don't set the PATH themselves
+    (except as described for --enable-path-for-scripts=PREFIX). Some
+    people like this while some think this is a bug. Those in the latter
+    group can easily patch the scripts before running the configure script
+    by taking advantage of a placeholder line in the scripts.
+
+    For example, to make the scripts prefix /usr/bin:/bin to PATH:
+
+        perl -pi -e 's|^#SET_PATH.*$|PATH=/usr/bin:/bin:\$PATH|' \
+                src/scripts/xz*.in
+
+
+4. Troubleshooting
+------------------
+
+4.1. "No C99 compiler was found."
+
+    You need a C99 compiler to build XZ Utils. If the configure script
+    cannot find a C99 compiler and you think you have such a compiler
+    installed, set the compiler command by passing CC=/path/to/c99 as
+    an argument to the configure script.
+
+    If you get this error even when you think your compiler supports C99,
+    you can override the test by passing ac_cv_prog_cc_c99= as an argument
+    to the configure script. The test for C99 compiler is not perfect (and
+    it is not as easy to make it perfect as it sounds), so sometimes this
+    may be needed. You will get a compile error if your compiler doesn't
+    support enough C99.
+
+
+4.2. "No POSIX conforming shell (sh) was found."
+
+    xzgrep and other scripts need a shell that (roughly) conforms
+    to POSIX. The configure script tries to find such a shell. If
+    it fails, you can force the shell to be used by passing
+    gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
+    script. Alternatively you can omit the installation of scripts and
+    this error by passing --disable-scripts to configure.
+
+
+4.3. configure works but build fails at crc32_x86.S
+
+    The easy fix is to pass --disable-assembler to the configure script.
+
+    The configure script determines if assembler code can be used by
+    looking at the configure triplet; there is currently no check if
+    the assembler code can actually actually be built. The x86 assembler
+    code should work on x86 GNU/Linux, *BSDs, Solaris, Darwin, MinGW,
+    Cygwin, and DJGPP. On other x86 systems, there may be problems and
+    the assembler code may need to be disabled with the configure option.
+
+    If you get this error when building for x86-64, you have specified or
+    the configure script has misguessed your architecture. Pass the
+    correct configure triplet using the --build=CPU-COMPANY-SYSTEM option
+    (see INSTALL.generic).
+
+
+4.4. Lots of warnings about symbol visibility
+
+    On some systems where symbol visibility isn't supported, GCC may
+    still accept the visibility options and attributes, which will make
+    configure think that visibility is supported. This will result in
+    many compiler warnings. You can avoid the warnings by forcing the
+    visibility support off by passing gl_cv_cc_visibility=no as an
+    argument to the configure script. This has no effect on the
+    resulting binaries, but fewer warnings looks nicer and may allow
+    using --enable-werror.
+
+
+4.5. "make check" fails
+
+    If the other tests pass but test_scripts.sh fails, then the problem
+    is in the scripts in src/scripts. Comparing the contents of
+    tests/xzgrep_test_output to tests/xzgrep_expected_output might
+    give a good idea about problems in xzgrep. One possibility is that
+    some tools are missing from the current PATH or the tools lack
+    support for some POSIX features. This can happen at least on
+    Solaris where the tools in /bin may be ancient but good enough
+    tools are available in /usr/xpg4/bin or /usr/xpg6/bin. For possible
+    fixes, see --enable-path-for-scripts=PREFIX in section 2 and the
+    older alternative method described in section 3.2 of this file.
+
+    If tests other than test_scripts.sh fail, a likely reason is that
+    libtool links the test programs against an installed version of
+    liblzma instead of the version that was just built. This is
+    obviously a bug which seems to happen on some platforms.
+    A workaround is to uninstall the old liblzma versions first.
+
+    If the problem isn't any of those described above, then it's likely
+    a bug in XZ Utils or in the compiler. See the platform-specific
+    notes in this file for possible known problems. Please report
+    a bug if you cannot solve the problem. See README for contact
+    information.
+
+
+4.6. liblzma.so (or similar) not found when running xz
+
+    If you installed the package with "make install" and get an error
+    about liblzma.so (or a similarly named file) being missing, try
+    running "ldconfig" to update the run-time linker cache (if your
+    operating system has such a command).

+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same time stamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+

+XZ Utils Release Notes
+======================
+
+5.3.1alpha (2018-04-29)
+
+    * All fixes from 5.2.4.
+
+    * Add lzma_file_info_decoder() into liblzma and use it in xz to
+      implement the --list feature.
+
+    * Capsicum sandbox support is enabled by default where available
+      (FreeBSD >= 10).
+
+
+5.2.5 (2020-03-17)
+
+    * liblzma:
+
+        - Fixed several C99/C11 conformance bugs. Now the code is clean
+          under gcc/clang -fsanitize=undefined. Some of these changes
+          might have a negative effect on performance with old GCC
+          versions or compilers other than GCC and Clang. The configure
+          option --enable-unsafe-type-punning can be used to (mostly)
+          restore the old behavior but it shouldn't normally be used.
+
+        - Improved API documentation of lzma_properties_decode().
+
+        - Added a very minor encoder speed optimization.
+
+    * xz:
+
+        - Fixed a crash in "xz -dcfv not_an_xz_file". All four options
+          were required to trigger it. The crash occurred in the
+          progress indicator code when xz was in passthru mode where
+          xz works like "cat".
+
+        - Fixed an integer overflow with 32-bit off_t. It could happen
+          when decompressing a file that has a long run of zero bytes
+          which xz would try to write as a sparse file. Since the build
+          system enables large file support by default, off_t is
+          normally 64-bit even on 32-bit systems.
+
+        - Fixes for --flush-timeout:
+            * Fix semi-busy-waiting.
+            * Avoid unneeded flushes when no new input has arrived
+              since the previous flush was completed.
+
+        - Added a special case for 32-bit xz: If --memlimit-compress is
+          used to specify a limit that exceeds 4020 MiB, the limit will
+          be set to 4020 MiB. The values "0" and "max" aren't affected
+          by this and neither is decompression. This hack can be
+          helpful when a 32-bit xz has access to 4 GiB address space
+          but the specified memlimit exceeds 4 GiB. This can happen
+          e.g. with some scripts.
+
+        - Capsicum sandbox is now enabled by default where available
+          (FreeBSD >= 10). The sandbox debug messages (xz -vv) were
+          removed since they seemed to be more annoying than useful.
+
+        - DOS build now requires DJGPP 2.05 instead of 2.04beta.
+          A workaround for a locale problem with DJGPP 2.05 was added.
+
+    * xzgrep and other scripts:
+
+        - Added a configure option --enable-path-for-scripts=PREFIX.
+          It is disabled by default except on Solaris where the default
+          is /usr/xpg4/bin. See INSTALL for details.
+
+        - Added a workaround for a POSIX shell detection problem on
+          Solaris.
+
+    * Build systems:
+
+        - Added preliminary build instructions for z/OS. See INSTALL
+          section 1.2.9.
+
+        - Experimental CMake support was added. It should work to build
+          static liblzma on a few operating systems. It may or may not
+          work to build shared liblzma. On some platforms it can build
+          xz and xzdec too but those are only for testing. See the
+          comment in the beginning of CMakeLists.txt for details.
+
+        - Visual Studio project files were updated.
+          WindowsTargetPlatformVersion was removed from VS2017 files
+          and set to "10.0" in the added VS2019 files. In the future
+          the VS project files will be removed when CMake support is
+          good enough.
+
+        - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED,
+          HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING.
+
+        - autogen.sh has a new optional dependency on po4a and a new
+          option --no-po4a to skip that step. This matters only if one
+          wants to remake the build files. po4a is used to update the
+          translated man pages but as long as the man pages haven't
+          been modified, there's nothing to update and one can use
+          --no-po4a to avoid the dependency on po4a.
+
+    * Translations:
+
+        - XZ Utils translations are now handled by the Translation
+          Project: https://translationproject.org/domain/xz.html
+
+        - All man pages are now included in German too.
+
+        - New xz translations: Brazilian Portuguese, Finnish,
+          Hungarian, Chinese (simplified), Chinese (traditional),
+          and Danish (partial translation)
+
+        - Updated xz translations: French, German, Italian, and Polish
+
+        - Unfortunately a few new xz translations weren't included due
+          to technical problems like too long lines in --help output or
+          misaligned column headings in tables. In the future, many of
+          these strings will be split and e.g. the table column
+          alignment will be handled in software. This should make the
+          strings easier to translate.
+
+
+5.2.4 (2018-04-29)
+
+    * liblzma:
+
+        - Allow 0 as memory usage limit instead of returning
+          LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified,
+          which effectively is the same as 0.
+
+        - Use "noexcept" keyword instead of "throw()" in the public
+          headers when a C++11 (or newer standard) compiler is used.
+
+        - Added a portability fix for recent Intel C Compilers.
+
+        - Microsoft Visual Studio build files have been moved under
+          windows/vs2013 and windows/vs2017.
+
+    * xz:
+
+        - Fix "xz --list --robot missing_or_bad_file.xz" which would
+          try to print an uninitialized string and thus produce garbage
+          output. Since the exit status is non-zero, most uses of such
+          a command won't try to interpret the garbage output.
+
+        - "xz --list foo.xz" could print "Internal error (bug)" in a
+          corner case where a specific memory usage limit had been set.
+
+
+5.2.3 (2016-12-30)
+
+    * xz:
+
+        - Always close a file before trying to delete it to avoid
+          problems on some operating system and file system combinations.
+
+        - Fixed copying of file timestamps on Windows.
+
+        - Added experimental (disabled by default) sandbox support using
+          Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
+
+    * C99/C11 conformance fixes to liblzma. The issues affected at least
+      some builds using link-time optimizations.
+
+    * Fixed bugs in the rarely-used function lzma_index_dup().
+
+    * Use of external SHA-256 code is now disabled by default.
+      It can still be enabled by passing --enable-external-sha256
+      to configure. The reasons to disable it by default (see INSTALL
+      for more details):
+
+        - Some OS-specific SHA-256 implementations conflict with
+          OpenSSL and cause problems in programs that link against both
+          liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
+          are affected.
+
+        - The internal SHA-256 is faster than the SHA-256 code in
+          some operating systems.
+
+    * Changed CPU core count detection to use sched_getaffinity() on
+      GNU/Linux and GNU/kFreeBSD.
+
+    * Fixes to the build-system and xz to make xz buildable even when
+      encoders, decoders, or threading have been disabled from libilzma
+      using configure options. These fixes added two new #defines to
+      config.h: HAVE_ENCODERS and HAVE_DECODERS.
+
+
+5.2.2 (2015-09-29)
+
+    * Fixed bugs in QNX-specific code.
+
+    * Omitted the use of pipe2() even if it is available to avoid
+      portability issues with some old Linux and glibc combinations.
+
+    * Updated German translation.
+
+    * Added project files to build static and shared liblzma (not the
+      whole XZ Utils) with Visual Studio 2013 update 2 or later.
+
+    * Documented that threaded decompression hasn't been implemented
+      yet. A 5.2.0 NEWS entry describing multi-threading support had
+      incorrectly said "decompression" when it should have said
+      "compression".
+
+
+5.2.1 (2015-02-26)
+
+    * Fixed a compression-ratio regression in fast mode of LZMA1 and
+      LZMA2. The bug is present in 5.1.4beta and 5.2.0 releases.
+
+    * Fixed a portability problem in xz that affected at least OpenBSD.
+
+    * Fixed xzdiff to be compatible with FreeBSD's mktemp which differs
+      from most other mktemp implementations.
+
+    * Changed CPU core count detection to use cpuset_getaffinity() on
+      FreeBSD.
+
+
+5.2.0 (2014-12-21)
+
+    Since 5.1.4beta:
+
+    * All fixes from 5.0.8
+
+    * liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset
+      was used.
+
+    * xzdiff: If mktemp isn't installed, mkdir will be used as
+      a fallback to create a temporary directory. Installing mktemp
+      is still recommended.
+
+    * Updated French, German, Italian, Polish, and Vietnamese
+      translations.
+
+    Summary of fixes and new features added in the 5.1.x development
+    releases:
+
+    * liblzma:
+
+        - Added support for multi-threaded compression. See the
+          lzma_mt structure, lzma_stream_encoder_mt(), and
+          lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
+          lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
+          in <lzma/hardware.h> for details.
+
+        - Made the uses of lzma_allocator const correct.
+
+        - Added lzma_block_uncomp_encode() to create uncompressed
+          .xz Blocks using LZMA2 uncompressed chunks.
+
+        - Added support for LZMA_IGNORE_CHECK.
+
+        - A few speed optimizations were made.
+
+        - Added support for symbol versioning. It is enabled by default
+          on GNU/Linux, other GNU-based systems, and FreeBSD.
+
+        - liblzma (not the whole XZ Utils) should now be buildable
+          with MSVC 2013 update 2 or later using windows/config.h.
+
+    * xz:
+
+        - Fixed a race condition in the signal handling. It was
+          possible that e.g. the first SIGINT didn't make xz exit
+          if reading or writing blocked and one had bad luck. The fix
+          is non-trivial, so as of writing it is unknown if it will be
+          backported to the v5.0 branch.
+
+        - Multi-threaded compression can be enabled with the
+          --threads (-T) option.
+          [Fixed: This originally said "decompression".]
+
+        - New command line options in xz: --single-stream,
+          --block-size=SIZE, --block-list=SIZES,
+          --flush-timeout=TIMEOUT, and --ignore-check.
+
+        - xz -lvv now shows the minimum xz version that is required to
+          decompress the file. Currently it is 5.0.0 for all supported
+          .xz files except files with empty LZMA2 streams require 5.0.2.
+
+    * xzdiff and xzgrep now support .lzo files if lzop is installed.
+      The .tzo suffix is also recognized as a shorthand for .tar.lzo.
+
+
+5.1.4beta (2014-09-14)
+
+    * All fixes from 5.0.6
+
+    * liblzma: Fixed the use of presets in threaded encoder
+      initialization.
+
+    * xz --block-list and --block-size can now be used together
+      in single-threaded mode. Previously the combination only
+      worked in multi-threaded mode.
+
+    * Added support for LZMA_IGNORE_CHECK to liblzma and made it
+      available in xz as --ignore-check.
+
+    * liblzma speed optimizations:
+
+        - Initialization of a new LZMA1 or LZMA2 encoder has been
+          optimized. (The speed of reinitializing an already-allocated
+          encoder isn't affected.) This helps when compressing many
+          small buffers with lzma_stream_buffer_encode() and other
+          similar situations where an already-allocated encoder state
+          isn't reused. This speed-up is visible in xz too if one
+          compresses many small files one at a time instead running xz
+          once and giving all files as command-line arguments.
+
+        - Buffer comparisons are now much faster when unaligned access
+          is allowed (configured with --enable-unaligned-access). This
+          speeds up encoding significantly. There is arch-specific code
+          for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best
+          results and there's no run-time CPU detection for now).
+          For other archs there is only generic code which probably
+          isn't as optimal as arch-specific solutions could be.
+
+        - A few speed optimizations were made to the SHA-256 code.
+          (Note that the builtin SHA-256 code isn't used on all
+          operating systems.)
+
+    * liblzma can now be built with MSVC 2013 update 2 or later
+      using windows/config.h.
+
+    * Vietnamese translation was added.
+
+
+5.1.3alpha (2013-10-26)
+
+    * All fixes from 5.0.5
+
+    * liblzma:
+
+        - Fixed a deadlock in the threaded encoder.
+
+        - Made the uses of lzma_allocator const correct.
+
+        - Added lzma_block_uncomp_encode() to create uncompressed
+          .xz Blocks using LZMA2 uncompressed chunks.
+
+        - Added support for native threads on Windows and the ability
+          to detect the number of CPU cores.
+
+    * xz:
+
+        - Fixed a race condition in the signal handling. It was
+          possible that e.g. the first SIGINT didn't make xz exit
+          if reading or writing blocked and one had bad luck. The fix
+          is non-trivial, so as of writing it is unknown if it will be
+          backported to the v5.0 branch.
+
+        - Made the progress indicator work correctly in threaded mode.
+
+        - Threaded encoder now works together with --block-list=SIZES.
+
+        - Added preliminary support for --flush-timeout=TIMEOUT.
+          It can be useful for (somewhat) real-time streaming. For
+          now the decompression side has to be done with something
+          else than the xz tool due to how xz does buffering, but this
+          should be fixed.
+
+
+5.1.2alpha (2012-07-04)
+
+    * All fixes from 5.0.3 and 5.0.4
+
+    * liblzma:
+
+        - Fixed a deadlock and an invalid free() in the threaded encoder.
+
+        - Added support for symbol versioning. It is enabled by default
+          on GNU/Linux, other GNU-based systems, and FreeBSD.
+
+        - Use SHA-256 implementation from the operating system if one is
+          available in libc, libmd, or libutil. liblzma won't use e.g.
+          OpenSSL or libgcrypt to avoid introducing new dependencies.
+
+        - Fixed liblzma.pc for static linking.
+
+        - Fixed a few portability bugs.
+
+    * xz --decompress --single-stream now fixes the input position after
+      successful decompression. Now the following works:
+
+          echo foo | xz > foo.xz
+          echo bar | xz >> foo.xz
+          ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz
+
+      Note that it doesn't work if the input is not seekable
+      or if there is Stream Padding between the concatenated
+      .xz Streams.
+
+    * xz -lvv now shows the minimum xz version that is required to
+      decompress the file. Currently it is 5.0.0 for all supported .xz
+      files except files with empty LZMA2 streams require 5.0.2.
+
+    * Added an *incomplete* implementation of --block-list=SIZES to xz.
+      It only works correctly in single-threaded mode and when
+      --block-size isn't used at the same time. --block-list allows
+      specifying the sizes of Blocks which can be useful e.g. when
+      creating files for random-access reading.
+
+
+5.1.1alpha (2011-04-12)
+
+    * All fixes from 5.0.2
+
+    * liblzma fixes that will also be included in 5.0.3:
+
+        - A memory leak was fixed.
+
+        - lzma_stream_buffer_encode() no longer creates an empty .xz
+          Block if encoding an empty buffer. Such an empty Block with
+          LZMA2 data would trigger a bug in 5.0.1 and older (see the
+          first bullet point in 5.0.2 notes). When releasing 5.0.2,
+          I thought that no encoder creates this kind of files but
+          I was wrong.
+
+        - Validate function arguments better in a few functions. Most
+          importantly, specifying an unsupported integrity check to
+          lzma_stream_buffer_encode() no longer creates a corrupt .xz
+          file. Probably no application tries to do that, so this
+          shouldn't be a big problem in practice.
+
+        - Document that lzma_block_buffer_encode(),
+          lzma_easy_buffer_encode(), lzma_stream_encoder(), and
+          lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
+
+        - The return values of the _memusage() functions are now
+          documented better.
+
+    * Support for multithreaded compression was added using the simplest
+      method, which splits the input data into blocks and compresses
+      them independently. Other methods will be added in the future.
+      The current method has room for improvement, e.g. it is possible
+      to reduce the memory usage.
+
+    * Added the options --single-stream and --block-size=SIZE to xz.
+
+    * xzdiff and xzgrep now support .lzo files if lzop is installed.
+      The .tzo suffix is also recognized as a shorthand for .tar.lzo.
+
+    * Support for short 8.3 filenames under DOS was added to xz. It is
+      experimental and may change before it gets into a stable release.
+
+
+5.0.8 (2014-12-21)
+
+    * Fixed an old bug in xzgrep that affected OpenBSD and probably
+      a few other operating systems too.
+
+    * Updated French and German translations.
+
+    * Added support for detecting the amount of RAM on AmigaOS/AROS.
+
+    * Minor build system updates.
+
+
+5.0.7 (2014-09-20)
+
+    * Fix regressions introduced in 5.0.6:
+
+        - Fix building with non-GNU make.
+
+        - Fix invalid Libs.private value in liblzma.pc which broke
+          static linking against liblzma if the linker flags were
+          taken from pkg-config.
+
+
+5.0.6 (2014-09-14)
+
+    * xzgrep now exits with status 0 if at least one file matched.
+
+    * A few minor portability and build system fixes
+
+
+5.0.5 (2013-06-30)
+
+    * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
+      .lzma files that have less common settings in the headers
+      (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
+      size greater than 256 GiB). The limitations existed to avoid false
+      positives when detecting .lzma files. The lc + lp <= 4 limitation
+      still remains since liblzma's LZMA decoder has that limitation.
+
+      NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT
+      affected by this change. They still consider uncommon .lzma headers
+      as not being in the .lzma format. Changing this would give way too
+      many false positives.
+
+    * xz:
+
+        - Interaction of preset and custom filter chain options was
+          made less illogical. This affects only certain less typical
+          uses cases so few people are expected to notice this change.
+
+          Now when a custom filter chain option (e.g. --lzma2) is
+          specified, all preset options (-0 ... -9, -e) earlier are on
+          the command line are completely forgotten. Similarly, when
+          a preset option is specified, all custom filter chain options
+          earlier on the command line are completely forgotten.
+
+          Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e"
+          which is equivalent to "xz -6e". Earlier -e didn't put xz back
+          into preset mode and thus the example command was equivalent
+          to "xz --lzma2=preset=5".
+
+          Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to
+          "xz -7". Earlier a custom filter chain option didn't make
+          xz forget the -e option so the example was equivalent to
+          "xz -7e".
+
+        - Fixes and improvements to error handling.
+
+        - Various fixes to the man page.
+
+    * xzless: Fixed to work with "less" versions 448 and later.
+
+    * xzgrep: Made -h an alias for --no-filename.
+
+    * Include the previously missing debug/translation.bash which can
+      be useful for translators.
+
+    * Include a build script for Mac OS X. This has been in the Git
+      repository since 2010 but due to a mistake in Makefile.am the
+      script hasn't been included in a release tarball before.
+
+
+5.0.4 (2012-06-22)
+
+    * liblzma:
+
+        - Fix lzma_index_init(). It could crash if memory allocation
+          failed.
+
+        - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
+          filter is used and the application only provides exactly as
+          much output space as is the uncompressed size of the file.
+
+        - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
+          check if the last call to lzma_code() really returned
+          LZMA_STREAM_END, which made the program think that truncated
+          files are valid.
+
+        - New example programs in doc/examples (old programs are now in
+          doc/examples_old). These have more comments and more detailed
+          error handling.
+
+    * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
+
+    * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
+      incorrectly printed the filename also in the "foo (x/x)" format.
+
+    * Fix exit status of "xzdiff foo.xz bar.xz".
+
+    * Fix exit status of "xzgrep foo binary_file".
+
+    * Fix portability to EBCDIC systems.
+
+    * Fix a configure issue on AIX with the XL C compiler. See INSTALL
+      for details.
+
+    * Update French, German, Italian, and Polish translations.
+
+
+5.0.3 (2011-05-21)
+
+    * liblzma fixes:
+
+        - A memory leak was fixed.
+
+        - lzma_stream_buffer_encode() no longer creates an empty .xz
+          Block if encoding an empty buffer. Such an empty Block with
+          LZMA2 data would trigger a bug in 5.0.1 and older (see the
+          first bullet point in 5.0.2 notes). When releasing 5.0.2,
+          I thought that no encoder creates this kind of files but
+          I was wrong.
+
+        - Validate function arguments better in a few functions. Most
+          importantly, specifying an unsupported integrity check to
+          lzma_stream_buffer_encode() no longer creates a corrupt .xz
+          file. Probably no application tries to do that, so this
+          shouldn't be a big problem in practice.
+
+        - Document that lzma_block_buffer_encode(),
+          lzma_easy_buffer_encode(), lzma_stream_encoder(), and
+          lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
+
+        - The return values of the _memusage() functions are now
+          documented better.
+
+    * Fix command name detection in xzgrep. xzegrep and xzfgrep now
+      correctly use egrep and fgrep instead of grep.
+
+    * French translation was added.
+
+
+5.0.2 (2011-04-01)
+
+    * LZMA2 decompressor now correctly accepts LZMA2 streams with no
+      uncompressed data. Previously it considered them corrupt. The
+      bug can affect applications that use raw LZMA2 streams. It is
+      very unlikely to affect .xz files because no compressor creates
+      .xz files with empty LZMA2 streams. (Empty .xz files are a
+      different thing than empty LZMA2 streams.)
+
+    * "xz --suffix=.foo filename.foo" now refuses to compress the
+      file due to it already having the suffix .foo. It was already
+      documented on the man page, but the code lacked the test.
+
+    * "xzgrep -l foo bar.xz" works now.
+
+    * Polish translation was added.
+
+
+5.0.1 (2011-01-29)
+
+    * xz --force now (de)compresses files that have setuid, setgid,
+      or sticky bit set and files that have multiple hard links.
+      The man page had it documented this way already, but the code
+      had a bug.
+
+    * gzip and bzip2 support in xzdiff was fixed.
+
+    * Portability fixes
+
+    * Minor fix to Czech translation
+
+
+5.0.0 (2010-10-23)
+
+    Only the most important changes compared to 4.999.9beta are listed
+    here. One change is especially important:
+
+      * The memory usage limit is now disabled by default. Some scripts
+        written before this change may have used --memory=max on xz command
+        line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED
+        NOW, because they interfere with user's ability to set the memory
+        usage limit himself. If user-specified limit causes problems to
+        your script, blame the user.
+
+    Other significant changes:
+
+      * Added support for XZ_DEFAULTS environment variable. This variable
+        allows users to set default options for xz, e.g. default memory
+        usage limit or default compression level. Scripts that use xz
+        must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT
+        instead if they need a way to pass options to xz via an
+        environment variable.
+
+      * The compression settings associated with the preset levels
+        -0 ... -9 have been changed. --extreme was changed a little too.
+        It is now less likely to make compression worse, but with some
+        files the new --extreme may compress slightly worse than the old
+        --extreme.
+
+      * If a preset level (-0 ... -9) is specified after a custom filter
+        chain options have been used (e.g. --lzma2), the custom filter
+        chain will be forgotten. Earlier the preset options were
+        completely ignored after custom filter chain options had been
+        seen.
+
+      * xz will create sparse files when decompressing if the uncompressed
+        data contains long sequences of binary zeros. This is done even
+        when writing to standard output that is connected to a regular
+        file and certain additional conditions are met to make it safe.
+
+      * Support for "xz --list" was added. Combine with --verbose or
+        --verbose --verbose (-vv) for detailed output.
+
+      * I had hoped that liblzma API would have been stable after
+        4.999.9beta, but there have been a couple of changes in the
+        advanced features, which don't affect most applications:
+
+          - Index handling code was revised. If you were using the old
+            API, you will get a compiler error (so it's easy to notice).
+
+          - A subtle but important change was made to the Block handling
+            API. lzma_block.version has to be initialized even for
+            lzma_block_header_decode(). Code that doesn't do it will work
+            for now, but might break in the future, which makes this API
+            change easy to miss.
+
+      * The major soname has been bumped to 5.0.0. liblzma API and ABI
+        are now stable, so the need to recompile programs linking against
+        liblzma shouldn't arise soon.

+
+0. Preface
+----------
+
+    This document is meant for people who create and maintain XZ Utils
+    packages for operating system distributions. The focus is on GNU/Linux
+    systems, but most things apply to other systems too.
+
+    While the standard "configure && make DESTDIR=$PKG install" should
+    give a pretty good package, there are some details which packagers
+    may want to tweak.
+
+    Packagers should also read the INSTALL file.
+
+
+1. Package naming
+-----------------
+
+    The preferred name for the XZ Utils package is "xz", because that's
+    the name of the upstream tarball. Naturally you may have good reasons
+    to use some other name; I won't get angry about it. ;-) It's just nice
+    to be able to point people to the correct package name without asking
+    what distro they have.
+
+    If your distro policy is to split things into small pieces, here is
+    one suggestion:
+
+        xz              xz, xzdec, scripts (xzdiff, xzgrep, etc.), docs
+        xz-lzma         lzma, unlzma, lzcat, lzgrep etc. symlinks and
+                        lzmadec binary for compatibility with LZMA Utils
+        liblzma         liblzma.so.*
+        liblzma-devel   liblzma.so, liblzma.a, API headers
+
+
+2. Package description
+----------------------
+
+    Here is a suggestion which you may use as the package description.
+    If you can use only one-line description, pick only the first line.
+    Naturally, feel free to use some other description if you find it
+    better, and maybe send it to me too.
+
+        Library and command line tools for XZ and LZMA compressed files
+
+        XZ Utils provide a general purpose data compression library
+        and command line tools. The native file format is the .xz
+        format, but also the legacy .lzma format is supported. The .xz
+        format supports multiple compression algorithms, of which LZMA2
+        is currently the primary algorithm. With typical files, XZ Utils
+        create about 30 % smaller files than gzip.
+
+    If you are splitting XZ Utils into multiple packages, here are some
+    suggestions for package descriptions:
+
+    xz:
+
+        Command line tools for XZ and LZMA compressed files
+
+        This package includes the xz compression tool and other command
+        line tools from XZ Utils. xz has command line syntax similar to
+        that of gzip. The native file format is the .xz format, but also
+        the legacy .lzma format is supported. The .xz format supports
+        multiple compression algorithms, of which LZMA2 is currently the
+        primary algorithm. With typical files, XZ Utils create about 30 %
+        smaller files than gzip.
+
+        Note that this package doesn't include the files needed for
+        LZMA Utils 4.32.x compatibility. Install also the xz-lzma
+        package to make XZ Utils emulate LZMA Utils 4.32.x.
+
+    xz-lzma:
+
+        LZMA Utils emulation with XZ Utils
+
+        This package includes executables and symlinks to make
+        XZ Utils emulate lzma, unlzma, lzcat, and other command
+        line tools found from the legacy LZMA Utils 4.32.x package.
+
+    liblzma:
+
+        Library for XZ and LZMA compressed files
+
+        liblzma is a general purpose data compression library with
+        an API similar to that of zlib. liblzma supports multiple
+        algorithms, of which LZMA2 is currently the primary algorithm.
+        The native file format is .xz, but also the legacy .lzma
+        format and raw streams (no headers at all) are supported.
+
+        This package includes the shared library.
+
+    liblzma-devel:
+
+        Library for XZ and LZMA compressed files
+
+        This package includes the API headers, static library, and
+        other development files related to liblzma.
+
+
+3. License
+----------
+
+    If the package manager supports a license field, you probably should
+    put GPLv2+ there (GNU GPL v2 or later). The interesting parts of
+    XZ Utils are in the public domain, but some less important files
+    ending up into the binary package are under GPLv2+. So it is simplest
+    to just say GPLv2+ if you cannot specify "public domain and GPLv2+".
+
+    If you split XZ Utils into multiple packages as described earlier
+    in this file, liblzma and liblzma-dev packages will contain only
+    public domain code (from XZ Utils at least; compiler or linker may
+    add some third-party code, which may be copyrighted).
+
+
+4. configure options
+--------------------
+
+    Unless you are building a package for a distribution that is meant
+    only for embedded systems, don't use the following configure options:
+
+        --enable-debug
+        --enable-encoders (*)
+        --enable-decoders
+        --enable-match-finders
+        --enable-checks
+        --enable-small (*)
+        --disable-threads (*)
+
+    (*) These are OK when building xzdec and lzmadec as described
+        in INSTALL.
+
+    xzdec and lzmadec don't provide any functionality that isn't already
+    available in the xz tool. Shipping xzdec and lzmadec without size
+    optimization and statically-linked liblzma isn't very useful. Doing
+    that would give users the xzdec man page, which may make it easier
+    for people to find out that such tools exists, but the executables
+    wouldn't have any advantage over the full-featured xz.
+
+
+5. Additional documentation
+---------------------------
+
+    "make install" copies some additional documentation to $docdir
+    (--docdir in configure). There is a copy of the GNU GPL v2, which
+    can be replaced with a symlink if your distro ships with shared
+    copies of the common license texts.
+
+    liblzma API is currently only documented using Doxygen tags in the
+    API headers. It hasn't been tested much how good results Doxygen
+    is able to make from the tags (e.g. Doxyfile might need tweaking,
+    the tagging may need to be improved etc.), so it might be simpler
+    to just let people read docs directly from the .h files for now,
+    and also save quite a bit in package size at the same time.
+
+
+6. Extra files
+--------------
+
+    The "extra" directory contains some small extra tools or other files.
+    The exact set of extra files can vary between XZ Utils releases. The
+    extra files have only limited use or they are too dangerous to be
+    put directly to $bindir (7z2lzma.sh is a good example, since it can
+    silently create corrupt output if certain conditions are not met).
+
+    If you feel like it, you may copy the extra directory under the doc
+    directory (e.g. /usr/share/doc/xz/extra). Maybe some people will find
+    them useful. However, most people needing these tools probably are
+    able to find them from the source package too.
+
+    The "debug" directory contains some tools that are useful only when
+    hacking on XZ Utils. Don't package these tools.
+
+
+7. Installing XZ Utils and LZMA Utils in parallel
+-------------------------------------------------
+
+    XZ Utils and LZMA Utils 4.32.x can be installed in parallel by
+    omitting the compatibility symlinks (lzma, unlzma, lzcat, lzgrep etc.)
+    from the XZ Utils package. It's probably a good idea to still package
+    the symlinks into a separate package so that users may choose if they
+    want to use XZ Utils or LZMA Utils for handling .lzma files.
+
+
+8. Example
+----------
+
+    Here is an example for i686 GNU/Linux that
+      - links xz and lzmainfo against shared liblzma;
+      - links size-optimized xzdec and lzmadec against static liblzma
+        while avoiding libpthread dependency;
+      - includes only shared liblzma in the final package; and
+      - copies also the "extra" directory to the package.
+
+    PKG=/tmp/xz-pkg
+    tar xf xz-x.y.z.tar.gz
+    cd xz-x.y.z
+    ./configure \
+            --prefix=/usr \
+            --disable-static \
+            --disable-xzdec \
+            --disable-lzmadec \
+            CFLAGS='-march=i686 -mtune=generic -O2'
+    make
+    make DESTDIR=$PKG install-strip
+    make clean
+    ./configure \
+            --prefix=/usr \
+            --disable-shared \
+            --disable-nls \
+            --disable-encoders \
+            --enable-small \
+            --disable-threads \
+            CFLAGS='-march=i686 -mtune=generic -Os'
+    make -C src/liblzma
+    make -C src/xzdec
+    make -C src/xzdec DESTDIR=$PKG install-strip
+    cp -a extra $PKG/usr/share/doc/xz
+

+-----------
+
+    XZ Utils provide a general-purpose data-compression library plus
+    command-line tools. The native file format is the .xz format, but
+    also the legacy .lzma format is supported. The .xz format supports
+    multiple compression algorithms, which are called "filters" in the
+    context of XZ Utils. The primary filter is currently LZMA2. With
+    typical files, XZ Utils create about 30 % smaller files than gzip.
+
+    To ease adapting support for the .xz format into existing applications
+    and scripts, the API of liblzma is somewhat similar to the API of the
+    popular zlib library. For the same reason, the command-line tool xz
+    has a command-line syntax similar to that of gzip.
+
+    When aiming for the highest compression ratio, the LZMA2 encoder uses
+    a lot of CPU time and may use, depending on the settings, even
+    hundreds of megabytes of RAM. However, in fast modes, the LZMA2 encoder
+    competes with bzip2 in compression speed, RAM usage, and compression
+    ratio.
+
+    LZMA2 is reasonably fast to decompress. It is a little slower than
+    gzip, but a lot faster than bzip2. Being fast to decompress means
+    that the .xz format is especially nice when the same file will be
+    decompressed very many times (usually on different computers), which
+    is the case e.g. when distributing software packages. In such
+    situations, it's not too bad if the compression takes some time,
+    since that needs to be done only once to benefit many people.
+
+    With some file types, combining (or "chaining") LZMA2 with an
+    additional filter can improve the compression ratio. A filter chain may
+    contain up to four filters, although usually only one or two are used.
+    For example, putting a BCJ (Branch/Call/Jump) filter before LZMA2
+    in the filter chain can improve compression ratio of executable files.
+
+    Since the .xz format allows adding new filter IDs, it is possible that
+    some day there will be a filter that is, for example, much faster to
+    compress than LZMA2 (but probably with worse compression ratio).
+    Similarly, it is possible that some day there is a filter that will
+    compress better than LZMA2.
+
+    XZ Utils supports multithreaded compression. XZ Utils doesn't support
+    multithreaded decompression yet. It has been planned though and taken
+    into account when designing the .xz file format. In the future, files
+    that were created in threaded mode can be decompressed in threaded
+    mode too.

+    AUTHORS             The main authors of XZ Utils
+    THANKS              Incomplete list of people who have helped making
+                        this software
+    NEWS                User-visible changes between XZ Utils releases
+    ChangeLog           Detailed list of changes (commit log)
+    TODO                Known bugs and some sort of to-do list
+
+    Note that only some of the above files are included in binary
+    packages.
+
+
+1.2. Documentation for command-line tools
+
+    The command-line tools are documented as man pages. In source code
+    releases (and possibly also in some binary packages), the man pages
+    are also provided in plain text (ASCII only) and PDF formats in the
+    directory "doc/man" to make the man pages more accessible to those
+    whose operating system doesn't provide an easy way to view man pages.
+
+
+1.3. Documentation for liblzma
+
+    The liblzma API headers include short docs about each function
+    and data type as Doxygen tags. These docs should be quite OK as
+    a quick reference.
+
+    There are a few example/tutorial programs that should help in
+    getting started with liblzma. In the source package the examples
+    are in "doc/examples" and in binary packages they may be under
+    "examples" in the same directory as this README.
+
+    Since the liblzma API has similarities to the zlib API, some people
+    may find it useful to read the zlib docs and tutorial too:
+
+        http://zlib.net/manual.html
+        http://zlib.net/zlib_how.html
+
+
+2. Version numbering
+--------------------
+
+    The version number format of XZ Utils is X.Y.ZS:
+
+      - X is the major version. When this is incremented, the library
+        API and ABI break.
+
+      - Y is the minor version. It is incremented when new features
+        are added without breaking the existing API or ABI. An even Y
+        indicates a stable release and an odd Y indicates unstable
+        (alpha or beta version).
+
+      - Z is the revision. This has a different meaning for stable and
+        unstable releases:
+
+          * Stable: Z is incremented when bugs get fixed without adding
+            any new features. This is intended to be convenient for
+            downstream distributors that want bug fixes but don't want
+            any new features to minimize the risk of introducing new bugs.
+
+          * Unstable: Z is just a counter. API or ABI of features added
+            in earlier unstable releases having the same X.Y may break.
+
+      - S indicates stability of the release. It is missing from the
+        stable releases, where Y is an even number. When Y is odd, S
+        is either "alpha" or "beta" to make it very clear that such
+        versions are not stable releases. The same X.Y.Z combination is
+        not used for more than one stability level, i.e. after X.Y.Zalpha,
+        the next version can be X.Y.(Z+1)beta but not X.Y.Zbeta.
+
+
+3. Reporting bugs
+-----------------
+
+    Naturally it is easiest for me if you already know what causes the
+    unexpected behavior. Even better if you have a patch to propose.
+    However, quite often the reason for unexpected behavior is unknown,
+    so here are a few things to do before sending a bug report:
+
+      1. Try to create a small example how to reproduce the issue.
+
+      2. Compile XZ Utils with debugging code using configure switches
+         --enable-debug and, if possible, --disable-shared. If you are
+         using GCC, use CFLAGS='-O0 -ggdb3'. Don't strip the resulting
+         binaries.
+
+      3. Turn on core dumps. The exact command depends on your shell;
+         for example in GNU bash it is done with "ulimit -c unlimited",
+         and in tcsh with "limit coredumpsize unlimited".
+
+      4. Try to reproduce the suspected bug. If you get "assertion failed"
+         message, be sure to include the complete message in your bug
+         report. If the application leaves a coredump, get a backtrace
+         using gdb:
+           $ gdb /path/to/app-binary   # Load the app to the debugger.
+           (gdb) core core   # Open the coredump.
+           (gdb) bt   # Print the backtrace. Copy & paste to bug report.
+           (gdb) quit   # Quit gdb.
+
+    Report your bug via email or IRC (see Contact information below).
+    Don't send core dump files or any executables. If you have a small
+    example file(s) (total size less than 256 KiB), please include
+    it/them as an attachment. If you have bigger test files, put them
+    online somewhere and include a URL to the file(s) in the bug report.
+
+    Always include the exact version number of XZ Utils in the bug report.
+    If you are using a snapshot from the git repository, use "git describe"
+    to get the exact snapshot version. If you are using XZ Utils shipped
+    in an operating system distribution, mention the distribution name,
+    distribution version, and exact xz package version; if you cannot
+    repeat the bug with the code compiled from unpatched source code,
+    you probably need to report a bug to your distribution's bug tracking
+    system.
+
+
+4. Translations
+---------------
+
+    The xz command line tool and all man pages can be translated.
+    The translations are handled via the Translation Project. If you
+    wish to help translating xz, please join the Translation Project:
+
+        https://translationproject.org/html/translators.html
+
+    Below are notes and testing instructions specific to xz
+    translations.
+
+    Testing can be done by installing xz into a temporary directory:
+
+        ./configure --disable-shared --prefix=/tmp/xz-test
+        # <Edit the .po file in the po directory.>
+        make -C po update-po
+        make install
+        bash debug/translation.bash | less
+        bash debug/translation.bash | less -S  # For --list outputs
+
+    Repeat the above as needed (no need to re-run configure though).
+
+    Note especially the following:
+
+      - The output of --help and --long-help must look nice on
+        an 80-column terminal. It's OK to add extra lines if needed.
+
+      - In contrast, don't add extra lines to error messages and such.
+        They are often preceded with e.g. a filename on the same line,
+        so you have no way to predict where to put a \n. Let the terminal
+        do the wrapping even if it looks ugly. Adding new lines will be
+        even uglier in the generic case even if it looks nice in a few
+        limited examples.
+
+      - Be careful with column alignment in tables and table-like output
+        (--list, --list --verbose --verbose, --info-memory, --help, and
+        --long-help):
+
+          * All descriptions of options in --help should start in the
+            same column (but it doesn't need to be the same column as
+            in the English messages; just be consistent if you change it).
+            Check that both --help and --long-help look OK, since they
+            share several strings.
+
+          * --list --verbose and --info-memory print lines that have
+            the format "Description:   %s". If you need a longer
+            description, you can put extra space between the colon
+            and %s. Then you may need to add extra space to other
+            strings too so that the result as a whole looks good (all
+            values start at the same column).
+
+          * The columns of the actual tables in --list --verbose --verbose
+            should be aligned properly. Abbreviate if necessary. It might
+            be good to keep at least 2 or 3 spaces between column headings
+            and avoid spaces in the headings so that the columns stand out
+            better, but this is a matter of opinion. Do what you think
+            looks best.
+
+      - Be careful to put a period at the end of a sentence when the
+        original version has it, and don't put it when the original
+        doesn't have it. Similarly, be careful with \n characters
+        at the beginning and end of the strings.
+
+      - Read the TRANSLATORS comments that have been extracted from the
+        source code and included in xz.pot. Some comments suggest
+        testing with a specific command which needs an .xz file. You
+        may use e.g. any tests/files/good-*.xz. However, these test
+        commands are included in translations.bash output, so reading
+        translations.bash output carefully can be enough.
+
+      - If you find language problems in the original English strings,
+        feel free to suggest improvements. Ask if something is unclear.
+
+      - The translated messages should be understandable (sometimes this
+        may be a problem with the original English messages too). Don't
+        make a direct word-by-word translation from English especially if
+        the result doesn't sound good in your language.
+
+    Thanks for your help!
+
+
+5. Other implementations of the .xz format
+------------------------------------------
+
+    7-Zip and the p7zip port of 7-Zip support the .xz format starting
+    from the version 9.00alpha.
+
+        http://7-zip.org/
+        http://p7zip.sourceforge.net/
+
+    XZ Embedded is a limited implementation written for use in the Linux
+    kernel, but it is also suitable for other embedded use.
+
+        https://tukaani.org/xz/embedded.html
+
+
+6. Contact information
+----------------------
+
+    If you have questions, bug reports, patches etc. related to XZ Utils,
+    contact Lasse Collin <[email protected]> (in Finnish or English).
+    I'm sometimes slow at replying. If you haven't got a reply within two
+    weeks, assume that your email has got lost and resend it or use IRC.
+
+    You can find me also from #tukaani on Freenode; my nick is Larhzu.
+    The channel tends to be pretty quiet, so just ask your question and
+    someone may wake up.

+
+XZ Utils To-Do List
+===================
+
+Known bugs
+----------
+
+    The test suite is too incomplete.
+
+    If the memory usage limit is less than about 13 MiB, xz is unable to
+    automatically scale down the compression settings enough even though
+    it would be  possible by switching from BT2/BT3/BT4 match finder to
+    HC3/HC4.
+
+    XZ Utils compress some files significantly worse than LZMA Utils.
+    This is due to faster compression presets used by XZ Utils, and
+    can often be worked around by using "xz --extreme". With some files
+    --extreme isn't enough though: it's most likely with files that
+    compress extremely well, so going from compression ratio of 0.003
+    to 0.004 means big relative increase in the compressed file size.
+
+    xz doesn't quote unprintable characters when it displays file names
+    given on the command line.
+
+    tuklib_exit() doesn't block signals => EINTR is possible.
+
+    SIGTSTP is not handled. If xz is stopped, the estimated remaining
+    time and calculated (de)compression speed won't make sense in the
+    progress indicator (xz --verbose).
+
+    If liblzma has created threads and fork() gets called, liblzma
+    code will break in the child process unless it calls exec() and
+    doesn't touch liblzma.
+
+
+Missing features
+----------------
+
+    Add support for storing metadata in .xz files. A preliminary
+    idea is to create a new Stream type for metadata. When both
+    metadata and data are wanted in the same .xz file, two or more
+    Streams would be concatenated.
+
+    The state stored in lzma_stream should be cloneable, which would
+    be mostly useful when using a preset dictionary in LZMA2, but
+    it may have other uses too. Compare to deflateCopy() in zlib.
+
+    Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and
+    other streams that don't have an end of payload marker.
+
+    Adjust dictionary size when the input file size is known.
+    Maybe do this only if an option is given.
+
+    xz doesn't support copying extended attributes, access control
+    lists etc. from source to target file.
+
+    Multithreaded compression:
+      - Reduce memory usage of the current method.
+      - Implement threaded match finders.
+      - Implement pigz-style threading in LZMA2.
+
+    Multithreaded decompression
+
+    Buffer-to-buffer coding could use less RAM (especially when
+    decompressing LZMA1 or LZMA2).
+
+    I/O library is not implemented (similar to gzopen() in zlib).
+    It will be a separate library that supports uncompressed, .gz,
+    .bz2, .lzma, and .xz files.
+
+    Support changing lzma_options_lzma.mode with lzma_filters_update().
+
+    Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at
+    Block and Stream boundaries.
+
+    lzma_strerror() to convert lzma_ret to human readable form?
+    This is tricky, because the same error codes are used with
+    slightly different meanings, and this cannot be fixed anymore.
+
+    Make it possible to adjust LZMA2 options in the middle of a Block
+    so that the encoding speed vs. compression ratio can be optimized
+    when the compressed data is streamed over network.
+
+    Improved BCJ filters. The current filters are small but they aren't
+    so great when compressing binary packages that contain various file
+    types. Specifically, they make things worse if there are static
+    libraries or Linux kernel modules. The filtering could also be
+    more effective (without getting overly complex), for example,
+    streamable variant BCJ2 from 7-Zip could be implemented.
+
+    Filter that autodetects specific data types in the input stream
+    and applies appropriate filters for the corrects parts of the input.
+    Perhaps combine this with the BCJ filter improvement point above.
+
+    Long-range LZ77 method as a separate filter or as a new LZMA2
+    match finder.
+
+
+Documentation
+-------------
+
+    More tutorial programs are needed for liblzma.
+
+    Document the LZMA1 and LZMA2 algorithms.
+
+
+Miscellaneous
+------------
+
+    Try to get the media type for .xz registered at IANA.

+Debug tools
+-----------
+
+    This directory contains a few tiny programs that may be helpful when
+    debugging XZ Utils.
+
+    These tools are not meant to be installed. Often one needs to edit
+    the source code a little to make the programs do the wanted things.
+    If you don't know how these programs could help you, it is likely
+    that they really are useless to you.
+
+    These aren't intended to be used as example programs. They take some
+    shortcuts here and there, which correct programs should not do. Many
+    possible errors (especially I/O errors) are ignored. Don't report
+    bugs or send patches to fix this kind of bugs.

+========================
+
+Introduction
+
+    The examples are written so that the same comments aren't
+    repeated (much) in later files.
+
+    On POSIX systems, the examples should build by just typing "make".
+
+    The examples that use stdin or stdout don't set stdin and stdout
+    to binary mode. On systems where it matters (e.g. Windows) it is
+    possible that the examples won't work without modification.
+
+
+List of examples
+
+    01_compress_easy.c                  Multi-call compression using
+                                        a compression preset
+
+    02_decompress.c                     Multi-call decompression
+
+    03_compress_custom.c                Like 01_compress_easy.c but using

+
+XZ Utils FAQ
+============
+
+Q:  What do the letters XZ mean?
+
+A:  Nothing. They are just two letters, which come from the file format
+    suffix .xz. The .xz suffix was selected, because it seemed to be
+    pretty much unused. It has no deeper meaning.
+
+
+Q:  What are LZMA and LZMA2?
+
+A:  LZMA stands for Lempel-Ziv-Markov chain-Algorithm. It is the name
+    of the compression algorithm designed by Igor Pavlov for 7-Zip.
+    LZMA is based on LZ77 and range encoding.
+
+    LZMA2 is an updated version of the original LZMA to fix a couple of
+    practical issues. In context of XZ Utils, LZMA is called LZMA1 to
+    emphasize that LZMA is not the same thing as LZMA2. LZMA2 is the
+    primary compression algorithm in the .xz file format.
+
+
+Q:  There are many LZMA related projects. How does XZ Utils relate to them?
+
+A:  7-Zip and LZMA SDK are the original projects. LZMA SDK is roughly
+    a subset of the 7-Zip source tree.
+
+    p7zip is 7-Zip's command-line tools ported to POSIX-like systems.
+
+    LZMA Utils provide a gzip-like lzma tool for POSIX-like systems.
+    LZMA Utils are based on LZMA SDK. XZ Utils are the successor to
+    LZMA Utils.
+
+    There are several other projects using LZMA. Most are more or less
+    based on LZMA SDK. See <http://7-zip.org/links.html>.
+
+
+Q:  Why is liblzma named liblzma if its primary file format is .xz?
+    Shouldn't it be e.g. libxz?
+
+A:  When the designing of the .xz format began, the idea was to replace
+    the .lzma format and use the same .lzma suffix. It would have been
+    quite OK to reuse the suffix when there were very few .lzma files
+    around. However, the old .lzma format became popular before the
+    new format was finished. The new format was renamed to .xz but the
+    name of liblzma wasn't changed.
+
+
+Q:  Do XZ Utils support the .7z format?
+
+A:  No. Use 7-Zip (Windows) or p7zip (POSIX-like systems) to handle .7z
+    files.
+
+
+Q:  I have many .tar.7z files. Can I convert them to .tar.xz without
+    spending hours recompressing the data?
+
+A:  In the "extra" directory, there is a script named 7z2lzma.bash which
+    is able to convert some .7z files to the .lzma format (not .xz). It
+    needs the 7za (or 7z) command from p7zip. The script may silently
+    produce corrupt output if certain assumptions are not met, so
+    decompress the resulting .lzma file and compare it against the
+    original before deleting the original file!
+
+
+Q:  I have many .lzma files. Can I quickly convert them to the .xz format?
+
+A:  For now, no. Since XZ Utils supports the .lzma format, it's usually
+    not too bad to keep the old files in the old format. If you want to
+    do the conversion anyway, you need to decompress the .lzma files and
+    then recompress to the .xz format.
+
+    Technically, there is a way to make the conversion relatively fast
+    (roughly twice the time that normal decompression takes). Writing
+    such a tool would take quite a bit of time though, and would probably
+    be useful to only a few people. If you really want such a conversion
+    tool, contact Lasse Collin and offer some money.
+
+
+Q:  I have installed xz, but my tar doesn't recognize .tar.xz files.
+    How can I extract .tar.xz files?
+
+A:  xz -dc foo.tar.xz | tar xf -
+
+
+Q:  Can I recover parts of a broken .xz file (e.g. a corrupted CD-R)?
+
+A:  It may be possible if the file consists of multiple blocks, which
+    typically is not the case if the file was created in single-threaded
+    mode. There is no recovery program yet.
+
+
+Q:  Is (some part of) XZ Utils patented?
+
+A:  Lasse Collin is not aware of any patents that could affect XZ Utils.
+    However, due to the nature of software patents, it's not possible to
+    guarantee that XZ Utils isn't affected by any third party patent(s).
+
+
+Q:  Where can I find documentation about the file format and algorithms?
+
+A:  The .xz format is documented in xz-file-format.txt. It is a container
+    format only, and doesn't include descriptions of any non-trivial
+    filters.
+
+    Documenting LZMA and LZMA2 is planned, but for now, there is no other
+    documentation than the source code. Before you begin, you should know
+    the basics of LZ77 and range-coding algorithms. LZMA is based on LZ77,
+    but LZMA is a lot more complex. Range coding is used to compress
+    the final bitstream like Huffman coding is used in Deflate.
+
+
+Q:  I cannot find BCJ and BCJ2 filters. Don't they exist in liblzma?
+
+A:  BCJ filter is called "x86" in liblzma. BCJ2 is not included,
+    because it requires using more than one encoded output stream.
+    A streamable version of BCJ2-style filtering is planned.
+
+
+Q:  I need to use a script that runs "xz -9". On a system with 256 MiB
+    of RAM, xz says that it cannot allocate memory. Can I make the
+    script work without modifying it?
+
+A:  Set a default memory usage limit for compression. You can do it e.g.
+    in a shell initialization script such as ~/.bashrc or /etc/profile:
+
+        XZ_DEFAULTS=--memlimit-compress=150MiB
+        export XZ_DEFAULTS
+
+    xz will then scale the compression settings down so that the given
+    memory usage limit is not reached. This way xz shouldn't run out
+    of memory.
+
+    Check also that memory-related resource limits are high enough.
+    On most systems, "ulimit -a" will show the current resource limits.
+
+
+Q:  How do I create files that can be decompressed with XZ Embedded?
+
+A:  See the documentation in XZ Embedded. In short, something like
+    this is a good start:
+
+        xz --check=crc32 --lzma2=preset=6e,dict=64KiB
+
+    Or if a BCJ filter is needed too, e.g. if compressing
+    a kernel image for PowerPC:
+
+        xz --check=crc32 --powerpc --lzma2=preset=6e,dict=64KiB
+
+    Adjust the dictionary size to get a good compromise between
+    compression ratio and decompressor memory usage. Note that
+    in single-call decompression mode of XZ Embedded, a big
+    dictionary doesn't increase memory usage.
+
+
+Q:  Will xz support threaded compression?
+
+A:  It is planned and has been taken into account when designing
+    the .xz file format. Eventually there will probably be three types
+    of threading, each method having its own advantages and disadvantages.
+
+    The simplest method is splitting the uncompressed data into blocks
+    and compressing them in parallel independent from each other.
+    Since the blocks are compressed independently, they can also be
+    decompressed independently. Together with the index feature in .xz,
+    this allows using threads to create .xz files for random-access
+    reading. This also makes threaded decompression possible, although
+    it is not clear if threaded decompression will ever be implemented.
+
+    The independent blocks method has a couple of disadvantages too. It
+    will compress worse than a single-block method. Often the difference
+    is not too big (maybe 1-2 %) but sometimes it can be too big. Also,
+    the memory usage of the compressor increases linearly when adding
+    threads.
+
+    Match finder parallelization is another threading method. It has
+    been in 7-Zip for ages. It doesn't affect compression ratio or
+    memory usage significantly. Among the three threading methods, only
+    this is useful when compressing small files (files that are not
+    significantly bigger than the dictionary). Unfortunately this method
+    scales only to about two CPU cores.
+
+    The third method is pigz-style threading (I use that name, because
+    pigz <http://www.zlib.net/pigz/> uses that method). It doesn't
+    affect compression ratio significantly and scales to many cores.
+    The memory usage scales linearly when threads are added. This isn't
+    significant with pigz, because Deflate uses only a 32 KiB dictionary,
+    but with LZMA2 the memory usage will increase dramatically just like
+    with the independent-blocks method. There is also a constant
+    computational overhead, which may make pigz-method a bit dull on
+    dual-core compared to the parallel match finder method, but with more
+    cores the overhead is not a big deal anymore.
+
+    Combining the threading methods will be possible and also useful.
+    E.g. combining match finder parallelization with pigz-style threading
+    can cut the memory usage by 50 %.
+
+    It is possible that the single-threaded method will be modified to
+    create files identical to the pigz-style method. We'll see once
+    pigz-style threading has been implemented in liblzma.
+
+
+Q:  How do I build a program that needs liblzmadec (lzmadec.h)?
+
+A:  liblzmadec is part of LZMA Utils. XZ Utils has liblzma, but no
+    liblzmadec. The code using liblzmadec should be ported to use
+    liblzma instead. If you cannot or don't want to do that, download
+    LZMA Utils from <https://tukaani.org/lzma/>.
+
+
+Q:  The default build of liblzma is too big. How can I make it smaller?
+
+A:  Give --enable-small to the configure script. Use also appropriate
+    --enable or --disable options to include only those filter encoders
+    and decoders and integrity checks that you actually need. Use
+    CFLAGS=-Os (with GCC) or equivalent to tell your compiler to optimize
+    for size. See INSTALL for information about configure options.
+
+    If the result is still too big, take a look at XZ Embedded. It is
+    a separate project, which provides a limited but significantly
+    smaller XZ decoder implementation than XZ Utils. You can find it
+    at <https://tukaani.org/xz/embedded.html>.

+
+History of LZMA Utils and XZ Utils
+==================================
+
+Tukaani distribution
+
+    In 2005, there was a small group working on the Tukaani distribution,
+    which was a Slackware fork. One of the project's goals was to fit the
+    distro on a single 700 MiB ISO-9660 image. Using LZMA instead of gzip
+    helped a lot. Roughly speaking, one could fit data that took 1000 MiB
+    in gzipped form into 700 MiB with LZMA. Naturally, the compression
+    ratio varied across packages, but this was what we got on average.
+
+    Slackware packages have traditionally had .tgz as the filename suffix,
+    which is an abbreviation of .tar.gz. A logical naming for LZMA
+    compressed packages was .tlz, being an abbreviation of .tar.lzma.
+
+    At the end of the year 2007, there was no distribution under the
+    Tukaani project anymore, but development of LZMA Utils was kept going.
+    Still, there were .tlz packages around, because at least Vector Linux
+    (a Slackware based distribution) used LZMA for its packages.
+
+    First versions of the modified pkgtools used the LZMA_Alone tool from
+    Igor Pavlov's LZMA SDK as is. It was fine, because users wouldn't need
+    to interact with LZMA_Alone directly. But people soon wanted to use
+    LZMA for other files too, and the interface of LZMA_Alone wasn't
+    comfortable for those used to gzip and bzip2.
+
+
+First steps of LZMA Utils
+
+    The first version of LZMA Utils (4.22.0) included a shell script called
+    lzmash. It was a wrapper that had a gzip-like command-line interface. It
+    used the LZMA_Alone tool from LZMA SDK to do all the real work. zgrep,
+    zdiff, and related scripts from gzip were adapted to work with LZMA and
+    were part of the first LZMA Utils release too.
+
+    LZMA Utils 4.22.0 included also lzmadec, which was a small (less than
+    10 KiB) decoder-only command-line tool. It was written on top of the
+    decoder-only C code found from the LZMA SDK. lzmadec was convenient in
+    situations where LZMA_Alone (a few hundred KiB) would be too big.
+
+    lzmash and lzmadec were written by Lasse Collin.
+
+
+Second generation
+
+    The lzmash script was an ugly and not very secure hack. The last
+    version of LZMA Utils to use lzmash was 4.27.1.
+
+    LZMA Utils 4.32.0beta1 introduced a new lzma command-line tool written
+    by Ville Koskinen. It was written in C++, and used the encoder and
+    decoder from C++ LZMA SDK with some little modifications. This tool
+    replaced both the lzmash script and the LZMA_Alone command-line tool
+    in LZMA Utils.
+
+    Introducing this new tool caused some temporary incompatibilities,
+    because the LZMA_Alone executable was simply named lzma like the new
+    command-line tool, but they had a completely different command-line
+    interface. The file format was still the same.
+
+    Lasse wrote liblzmadec, which was a small decoder-only library based
+    on the C code found from LZMA SDK. liblzmadec had an API similar to
+    zlib, although there were some significant differences, which made it
+    non-trivial to use it in some applications designed for zlib and
+    libbzip2.
+
+    The lzmadec command-line tool was converted to use liblzmadec.
+
+    Alexandre Sauvé helped converting the build system to use GNU
+    Autotools. This made it easier to test for certain less portable
+    features needed by the new command-line tool.
+
+    Since the new command-line tool never got completely finished (for
+    example, it didn't support the LZMA_OPT environment variable), the
+    intent was to not call 4.32.x stable. Similarly, liblzmadec wasn't
+    polished, but appeared to work well enough, so some people started
+    using it too.
+
+    Because the development of the third generation of LZMA Utils was
+    delayed considerably (3-4 years), the 4.32.x branch had to be kept
+    maintained. It got some bug fixes now and then, and finally it was
+    decided to call it stable, although most of the missing features were
+    never added.
+
+
+File format problems
+
+    The file format used by LZMA_Alone was primitive. It was designed with
+    embedded systems in mind, and thus provided only a minimal set of
+    features. The two biggest problems for non-embedded use were the lack
+    of magic bytes and an integrity check.
+
+    Igor and Lasse started developing a new file format with some help
+    from Ville Koskinen. Also Mark Adler, Mikko Pouru, H. Peter Anvin,
+    and Lars Wirzenius helped with some minor things at some point of the
+    development. Designing the new format took quite a long time (actually,
+    too long a time would be a more appropriate expression). It was mostly
+    because Lasse was quite slow at getting things done due to personal
+    reasons.
+
+    Originally the new format was supposed to use the same .lzma suffix
+    that was already used by the old file format. Switching to the new
+    format wouldn't have caused much trouble when the old format wasn't
+    used by many people. But since the development of the new format took
+    such a long time, the old format got quite popular, and it was decided
+    that the new file format must use a different suffix.
+
+    It was decided to use .xz as the suffix of the new file format. The
+    first stable .xz file format specification was finally released in
+    December 2008. In addition to fixing the most obvious problems of
+    the old .lzma format, the .xz format added some new features like
+    support for multiple filters (compression algorithms), filter chaining
+    (like piping on the command line), and limited random-access reading.
+
+    Currently the primary compression algorithm used in .xz is LZMA2.
+    It is an extension on top of the original LZMA to fix some practical
+    problems: LZMA2 adds support for flushing the encoder, uncompressed
+    chunks, eases stateful decoder implementations, and improves support
+    for multithreading. Since LZMA2 is better than the original LZMA, the
+    original LZMA is not supported in .xz.
+
+
+Transition to XZ Utils
+
+    The early versions of XZ Utils were called LZMA Utils. The first
+    releases were 4.42.0alphas. They dropped the rest of the C++ LZMA SDK.
+    The code was still directly based on LZMA SDK but ported to C and
+    converted from a callback API to a stateful API. Later, Igor Pavlov
+    made a C version of the LZMA encoder too; these ports from C++ to C
+    were independent in LZMA SDK and LZMA Utils.
+
+    The core of the new LZMA Utils was liblzma, a compression library with
+    a zlib-like API. liblzma supported both the old and new file format.
+    The gzip-like lzma command-line tool was rewritten to use liblzma.
+
+    The new LZMA Utils code base was renamed to XZ Utils when the name
+    of the new file format had been decided. The liblzma compression
+    library retained its name though, because changing it would have
+    caused unnecessary breakage in applications already using the early
+    liblzma snapshots.
+
+    The xz command-line tool can emulate the gzip-like lzma tool by
+    creating appropriate symlinks (e.g. lzma -> xz). Thus, practically
+    all scripts using the lzma tool from LZMA Utils will work as is with
+    XZ Utils (and will keep using the old .lzma format). Still, the .lzma
+    format is more or less deprecated. XZ Utils will keep supporting it,
+    but new applications should use the .xz format, and migrating old
+    applications to .xz is often a good idea too.

+
+        This document describes the .lzma file format, which is
+        sometimes also called LZMA_Alone format. It is a legacy file
+        format, which is being or has been replaced by the .xz format.
+        The MIME type of the .lzma format is `application/x-lzma'.
+
+        The most commonly used software to handle .lzma files are
+        LZMA SDK, LZMA Utils, 7-Zip, and XZ Utils. This document
+        describes some of the differences between these implementations

+
+        The .lzma format file consist of 13-byte Header followed by
+        the LZMA Compressed Data.
+
+        Unlike the .gz, .bz2, and .xz formats, it is not possible to
+        concatenate multiple .lzma files as is and expect the
+        decompression tool to decode the resulting file as if it were
+        a single .lzma file.
+
+        For example, the command line tools from LZMA Utils and
+        LZMA SDK silently ignore all the data after the first .lzma
+        stream. In contrast, the command line tool from XZ Utils
+        considers the .lzma file to be corrupt if there is data after
+        the first .lzma stream.

+        | Properties |  Dictionary Size  |   Uncompressed Size   |
+        +------------+----+----+----+----+--+--+--+--+--+--+--+--+
+
+
+1.1.1. Properties
+
+        The Properties field contains three properties. An abbreviation
+        is given in parentheses, followed by the value range of the
+        property. The field consists of
+
+            1) the number of literal context bits (lc, [0, 8]);
+            2) the number of literal position bits (lp, [0, 4]); and
+            3) the number of position bits (pb, [0, 4]).
+
+        The properties are encoded using the following formula:
+
+            Properties = (pb * 5 + lp) * 9 + lc
+
+        The following C code illustrates a straightforward way to
+        decode the Properties field:
+
+            uint8_t lc, lp, pb;
+            uint8_t prop = get_lzma_properties();
+            if (prop > (4 * 5 + 4) * 9 + 8)
+                return LZMA_PROPERTIES_ERROR;
+
+            pb = prop / (9 * 5);
+            prop -= pb * 9 * 5;
+            lp = prop / 9;
+            lc = prop - lp * 9;
+
+        XZ Utils has an additional requirement: lc + lp <= 4. Files
+        which don't follow this requirement cannot be decompressed
+        with XZ Utils. Usually this isn't a problem since the most
+        common lc/lp/pb values are 3/0/2. It is the only lc/lp/pb
+        combination that the files created by LZMA Utils can have,
+        but LZMA Utils can decompress files with any lc/lp/pb.
+
+
+1.1.2. Dictionary Size
+
+        Dictionary Size is stored as an unsigned 32-bit little endian
+        integer. Any 32-bit value is possible, but for maximum
+        portability, only sizes of 2^n and 2^n + 2^(n-1) should be
+        used.
+
+        LZMA Utils creates only files with dictionary size 2^n,
+        16 <= n <= 25. LZMA Utils can decompress files with any
+        dictionary size.
+
+        XZ Utils creates and decompresses .lzma files only with
+        dictionary sizes 2^n and 2^n + 2^(n-1). If some other
+        dictionary size is specified when compressing, the value
+        stored in the Dictionary Size field is a rounded up, but the
+        specified value is still used in the actual compression code.
+
+
+1.1.3. Uncompressed Size
+
+        Uncompressed Size is stored as unsigned 64-bit little endian
+        integer. A special value of 0xFFFF_FFFF_FFFF_FFFF indicates
+        that Uncompressed Size is unknown. End of Payload Marker (*)
+        is used if and only if Uncompressed Size is unknown.
+
+        XZ Utils rejects files whose Uncompressed Size field specifies
+        a known size that is 256 GiB or more. This is to reject false
+        positives when trying to guess if the input file is in the
+        .lzma format. When Uncompressed Size is unknown, there is no
+        limit for the uncompressed size of the file.
+
+        (*) Some tools use the term End of Stream (EOS) marker
+            instead of End of Payload Marker.
+
+
+1.2. LZMA Compressed Data
+
+        Detailed description of the format of this field is out of
+        scope of this document.

+        document are to be interpreted as described in [RFC-2119].
+
+        Indicating a warning means displaying a message, returning
+        appropriate exit status, or doing something else to let the
+        user know that something worth warning occurred. The operation
+        SHOULD still finish if a warning is indicated.
+
+        Indicating an error means displaying a message, returning
+        appropriate exit status, or doing something else to let the
+        user know that something prevented successfully finishing the
+        operation. The operation MUST be aborted once an error has
+        been indicated.
+
+
+1.1. Byte and Its Representation
+
+        In this document, byte is always 8 bits.
+
+        A "null byte" has all bits unset. That is, the value of a null
+        byte is 0x00.
+
+        To represent byte blocks, this document uses notation that
+        is similar to the notation used in [RFC-1952]:
+
+            +-------+
+            |  Foo  |   One byte.
+            +-------+
+
+            +---+---+
+            |  Foo  |   Two bytes; that is, some of the vertical bars
+            +---+---+   can be missing.
+
+            +=======+
+            |  Foo  |   Zero or more bytes.
+            +=======+
+
+        In this document, a boxed byte or a byte sequence declared
+        using this notation is called "a field". The example field
+        above would be called "the Foo field" or plain "Foo".
+
+        If there are many fields, they may be split to multiple lines.
+        This is indicated with an arrow ("--->"):
+
+            +=====+
+            | Foo |
+            +=====+
+
+                 +=====+
+            ---> | Bar |
+                 +=====+
+
+        The above is equivalent to this:
+
+            +=====+=====+
+            | Foo | Bar |
+            +=====+=====+
+
+
+1.2. Multibyte Integers
+
+        Multibyte integers of static length, such as CRC values,
+        are stored in little endian byte order (least significant
+        byte first).
+
+        When smaller values are more likely than bigger values (for
+        example file sizes), multibyte integers are encoded in a
+        variable-length representation:
+          - Numbers in the range [0, 127] are copied as is, and take
+            one byte of space.
+          - Bigger numbers will occupy two or more bytes. All but the
+            last byte of the multibyte representation have the highest
+            (eighth) bit set.
+
+        For now, the value of the variable-length integers is limited
+        to 63 bits, which limits the encoded size of the integer to
+        nine bytes. These limits may be increased in the future if
+        needed.
+
+        The following C code illustrates encoding and decoding of
+        variable-length integers. The functions return the number of
+        bytes occupied by the integer (1-9), or zero on error.
+
+            #include <stddef.h>
+            #include <inttypes.h>
+
+            size_t
+            encode(uint8_t buf[static 9], uint64_t num)
+            {
+                if (num > UINT64_MAX / 2)
+                    return 0;
+
+                size_t i = 0;
+
+                while (num >= 0x80) {
+                    buf[i++] = (uint8_t)(num) | 0x80;
+                    num >>= 7;
+                }
+
+                buf[i++] = (uint8_t)(num);
+
+                return i;
+            }
+
+            size_t
+            decode(const uint8_t buf[], size_t size_max, uint64_t *num)
+            {
+                if (size_max == 0)
+                    return 0;
+
+                if (size_max > 9)
+                    size_max = 9;
+
+                *num = buf[0] & 0x7F;
+                size_t i = 0;
+
+                while (buf[i++] & 0x80) {
+                    if (i >= size_max || buf[i] == 0x00)
+                        return 0;
+
+                    *num |= (uint64_t)(buf[i] & 0x7F) << (i * 7);
+                }
+
+                return i;
+            }
+
+
+2. Overall Structure of .xz File
+
+        A standalone .xz files consist of one or more Streams which may
+        have Stream Padding between or after them:
+
+            +========+================+========+================+
+            | Stream | Stream Padding | Stream | Stream Padding | ...
+            +========+================+========+================+
+
+        The sizes of Stream and Stream Padding are always multiples
+        of four bytes, thus the size of every valid .xz file MUST be
+        a multiple of four bytes.
+
+        While a typical file contains only one Stream and no Stream
+        Padding, a decoder handling standalone .xz files SHOULD support
+        files that have more than one Stream or Stream Padding.
+
+        In contrast to standalone .xz files, when the .xz file format
+        is used as an internal part of some other file format or
+        communication protocol, it usually is expected that the decoder
+        stops after the first Stream, and doesn't look for Stream
+        Padding or possibly other Streams.
+
+
+2.1. Stream
+
+        +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+     +=======+
+        |     Stream Header     | Block | Block | ... | Block |
+        +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+     +=======+
+
+             +=======+-+-+-+-+-+-+-+-+-+-+-+-+
+        ---> | Index |     Stream Footer     |
+             +=======+-+-+-+-+-+-+-+-+-+-+-+-+
+
+        All the above fields have a size that is a multiple of four. If
+        Stream is used as an internal part of another file format, it
+        is RECOMMENDED to make the Stream start at an offset that is
+        a multiple of four bytes.
+
+        Stream Header, Index, and Stream Footer are always present in
+        a Stream. The maximum size of the Index field is 16 GiB (2^34).
+
+        There are zero or more Blocks. The maximum number of Blocks is
+        limited only by the maximum size of the Index field.
+
+        Total size of a Stream MUST be less than 8 EiB (2^63 bytes).
+        The same limit applies to the total amount of uncompressed
+        data stored in a Stream.
+
+        If an implementation supports handling .xz files with multiple
+        concatenated Streams, it MAY apply the above limits to the file
+        as a whole instead of limiting per Stream basis.
+
+
+2.1.1. Stream Header
+
+        +---+---+---+---+---+---+-------+------+--+--+--+--+
+        |  Header Magic Bytes   | Stream Flags |   CRC32   |
+        +---+---+---+---+---+---+-------+------+--+--+--+--+
+
+
+2.1.1.1. Header Magic Bytes
+
+        The first six (6) bytes of the Stream are so called Header
+        Magic Bytes. They can be used to identify the file type.
+
+            Using a C array and ASCII:
+            const uint8_t HEADER_MAGIC[6]
+                    = { 0xFD, '7', 'z', 'X', 'Z', 0x00 };
+
+            In plain hexadecimal:
+            FD 37 7A 58 5A 00
+
+        Notes:
+          - The first byte (0xFD) was chosen so that the files cannot
+            be erroneously detected as being in .lzma format, in which
+            the first byte is in the range [0x00, 0xE0].
+          - The sixth byte (0x00) was chosen to prevent applications
+            from misdetecting the file as a text file.
+
+        If the Header Magic Bytes don't match, the decoder MUST
+        indicate an error.
+
+
+2.1.1.2. Stream Flags
+
+        The first byte of Stream Flags is always a null byte. In the
+        future, this byte may be used to indicate a new Stream version
+        or other Stream properties.
+
+        The second byte of Stream Flags is a bit field:
+
+            Bit(s)  Mask  Description
+             0-3    0x0F  Type of Check (see Section 3.4):
+                              ID    Size      Check name
+                              0x00   0 bytes  None
+                              0x01   4 bytes  CRC32
+                              0x02   4 bytes  (Reserved)
+                              0x03   4 bytes  (Reserved)
+                              0x04   8 bytes  CRC64
+                              0x05   8 bytes  (Reserved)
+                              0x06   8 bytes  (Reserved)
+                              0x07  16 bytes  (Reserved)
+                              0x08  16 bytes  (Reserved)
+                              0x09  16 bytes  (Reserved)
+                              0x0A  32 bytes  SHA-256
+                              0x0B  32 bytes  (Reserved)
+                              0x0C  32 bytes  (Reserved)
+                              0x0D  64 bytes  (Reserved)
+                              0x0E  64 bytes  (Reserved)
+                              0x0F  64 bytes  (Reserved)
+             4-7    0xF0  Reserved for future use; MUST be zero for now.
+
+        Implementations SHOULD support at least the Check IDs 0x00
+        (None) and 0x01 (CRC32). Supporting other Check IDs is
+        OPTIONAL. If an unsupported Check is used, the decoder SHOULD
+        indicate a warning or error.
+
+        If any reserved bit is set, the decoder MUST indicate an error.
+        It is possible that there is a new field present which the
+        decoder is not aware of, and can thus parse the Stream Header
+        incorrectly.
+
+
+2.1.1.3. CRC32
+
+        The CRC32 is calculated from the Stream Flags field. It is
+        stored as an unsigned 32-bit little endian integer. If the
+        calculated value does not match the stored one, the decoder
+        MUST indicate an error.
+
+        The idea is that Stream Flags would always be two bytes, even
+        if new features are needed. This way old decoders will be able
+        to verify the CRC32 calculated from Stream Flags, and thus
+        distinguish between corrupt files (CRC32 doesn't match) and
+        files that the decoder doesn't support (CRC32 matches but
+        Stream Flags has reserved bits set).
+
+
+2.1.2. Stream Footer
+
+        +-+-+-+-+---+---+---+---+-------+------+----------+---------+
+        | CRC32 | Backward Size | Stream Flags | Footer Magic Bytes |
+        +-+-+-+-+---+---+---+---+-------+------+----------+---------+
+
+
+2.1.2.1. CRC32
+
+        The CRC32 is calculated from the Backward Size and Stream Flags
+        fields. It is stored as an unsigned 32-bit little endian
+        integer. If the calculated value does not match the stored one,
+        the decoder MUST indicate an error.
+
+        The reason to have the CRC32 field before the Backward Size and
+        Stream Flags fields is to keep the four-byte fields aligned to
+        a multiple of four bytes.
+
+
+2.1.2.2. Backward Size
+
+        Backward Size is stored as a 32-bit little endian integer,
+        which indicates the size of the Index field as multiple of
+        four bytes, minimum value being four bytes:
+
+            real_backward_size = (stored_backward_size + 1) * 4;
+
+        If the stored value does not match the real size of the Index
+        field, the decoder MUST indicate an error.
+
+        Using a fixed-size integer to store Backward Size makes
+        it slightly simpler to parse the Stream Footer when the
+        application needs to parse the Stream backwards.
+
+
+2.1.2.3. Stream Flags
+
+        This is a copy of the Stream Flags field from the Stream
+        Header. The information stored to Stream Flags is needed
+        when parsing the Stream backwards. The decoder MUST compare
+        the Stream Flags fields in both Stream Header and Stream
+        Footer, and indicate an error if they are not identical.
+
+
+2.1.2.4. Footer Magic Bytes
+
+        As the last step of the decoding process, the decoder MUST
+        verify the existence of Footer Magic Bytes. If they don't
+        match, an error MUST be indicated.
+
+            Using a C array and ASCII:
+            const uint8_t FOOTER_MAGIC[2] = { 'Y', 'Z' };
+
+            In hexadecimal:
+            59 5A
+
+        The primary reason to have Footer Magic Bytes is to make
+        it easier to detect incomplete files quickly, without
+        uncompressing. If the file does not end with Footer Magic Bytes
+        (excluding Stream Padding described in Section 2.2), it cannot
+        be undamaged, unless someone has intentionally appended garbage
+        after the end of the Stream.
+
+
+2.2. Stream Padding
+
+        Only the decoders that support decoding of concatenated Streams
+        MUST support Stream Padding.
+
+        Stream Padding MUST contain only null bytes. To preserve the
+        four-byte alignment of consecutive Streams, the size of Stream
+        Padding MUST be a multiple of four bytes. Empty Stream Padding
+        is allowed. If these requirements are not met, the decoder MUST
+        indicate an error.
+
+        Note that non-empty Stream Padding is allowed at the end of the
+        file; there doesn't need to be a new Stream after non-empty
+        Stream Padding. This can be convenient in certain situations
+        [GNU-tar].
+
+        The possibility of Stream Padding MUST be taken into account
+        when designing an application that parses Streams backwards,
+        and the application supports concatenated Streams.

+        ---> | Header Padding |   CRC32   |
+             +================+--+--+--+--+
+
+
+3.1.1. Block Header Size
+
+        This field overlaps with the Index Indicator field (see
+        Section 4.1).
+
+        This field contains the size of the Block Header field,
+        including the Block Header Size field itself. Valid values are
+        in the range [0x01, 0xFF], which indicate the size of the Block
+        Header as multiples of four bytes, minimum size being eight
+        bytes:
+
+            real_header_size = (encoded_header_size + 1) * 4;
+
+        If a Block Header bigger than 1024 bytes is needed in the
+        future, a new field can be added between the Block Header and
+        Compressed Data fields. The presence of this new field would
+        be indicated in the Block Header field.
+
+
+3.1.2. Block Flags
+
+        The Block Flags field is a bit field:
+
+            Bit(s)  Mask  Description
+             0-1    0x03  Number of filters (1-4)
+             2-5    0x3C  Reserved for future use; MUST be zero for now.
+              6     0x40  The Compressed Size field is present.
+              7     0x80  The Uncompressed Size field is present.
+
+        If any reserved bit is set, the decoder MUST indicate an error.
+        It is possible that there is a new field present which the
+        decoder is not aware of, and can thus parse the Block Header
+        incorrectly.
+
+
+3.1.3. Compressed Size
+
+        This field is present only if the appropriate bit is set in
+        the Block Flags field (see Section 3.1.2).
+
+        The Compressed Size field contains the size of the Compressed
+        Data field, which MUST be non-zero. Compressed Size is stored
+        using the encoding described in Section 1.2. If the Compressed
+        Size doesn't match the size of the Compressed Data field, the
+        decoder MUST indicate an error.
+
+
+3.1.4. Uncompressed Size
+
+        This field is present only if the appropriate bit is set in
+        the Block Flags field (see Section 3.1.2).
+
+        The Uncompressed Size field contains the size of the Block
+        after uncompressing. Uncompressed Size is stored using the
+        encoding described in Section 1.2. If the Uncompressed Size
+        does not match the real uncompressed size, the decoder MUST
+        indicate an error.
+
+        Storing the Compressed Size and Uncompressed Size fields serves
+        several purposes:
+          - The decoder knows how much memory it needs to allocate
+            for a temporary buffer in multithreaded mode.
+          - Simple error detection: wrong size indicates a broken file.
+          - Seeking forwards to a specific location in streamed mode.
+
+        It should be noted that the only reliable way to determine
+        the real uncompressed size is to uncompress the Block,
+        because the Block Header and Index fields may contain
+        (intentionally or unintentionally) invalid information.
+
+
+3.1.5. List of Filter Flags
+
+        +================+================+     +================+
+        | Filter 0 Flags | Filter 1 Flags | ... | Filter n Flags |
+        +================+================+     +================+
+
+        The number of Filter Flags fields is stored in the Block Flags
+        field (see Section 3.1.2).
+
+        The format of each Filter Flags field is as follows:
+
+            +===========+====================+===================+
+            | Filter ID | Size of Properties | Filter Properties |
+            +===========+====================+===================+
+
+        Both Filter ID and Size of Properties are stored using the
+        encoding described in Section 1.2. Size of Properties indicates
+        the size of the Filter Properties field as bytes. The list of
+        officially defined Filter IDs and the formats of their Filter
+        Properties are described in Section 5.3.
+
+        Filter IDs greater than or equal to 0x4000_0000_0000_0000
+        (2^62) are reserved for implementation-specific internal use.
+        These Filter IDs MUST never be used in List of Filter Flags.
+
+
+3.1.6. Header Padding
+
+        This field contains as many null byte as it is needed to make
+        the Block Header have the size specified in Block Header Size.
+        If any of the bytes are not null bytes, the decoder MUST
+        indicate an error. It is possible that there is a new field
+        present which the decoder is not aware of, and can thus parse
+        the Block Header incorrectly.
+
+
+3.1.7. CRC32
+
+        The CRC32 is calculated over everything in the Block Header
+        field except the CRC32 field itself. It is stored as an
+        unsigned 32-bit little endian integer. If the calculated
+        value does not match the stored one, the decoder MUST indicate
+        an error.
+
+        By verifying the CRC32 of the Block Header before parsing the
+        actual contents allows the decoder to distinguish between
+        corrupt and unsupported files.
+
+
+3.2. Compressed Data
+
+        The format of Compressed Data depends on Block Flags and List
+        of Filter Flags. Excluding the descriptions of the simplest
+        filters in Section 5.3, the format of the filter-specific
+        encoded data is out of scope of this document.
+
+
+3.3. Block Padding
+
+        Block Padding MUST contain 0-3 null bytes to make the size of
+        the Block a multiple of four bytes. This can be needed when
+        the size of Compressed Data is not a multiple of four. If any
+        of the bytes in Block Padding are not null bytes, the decoder
+        MUST indicate an error.
+
+
+3.4. Check
+
+        The type and size of the Check field depends on which bits
+        are set in the Stream Flags field (see Section 2.1.1.2).
+
+        The Check, when used, is calculated from the original
+        uncompressed data. If the calculated Check does not match the
+        stored one, the decoder MUST indicate an error. If the selected
+        type of Check is not supported by the decoder, it SHOULD
+        indicate a warning or error.
+
+
+4. Index
+
+        +-----------------+===================+
+        | Index Indicator | Number of Records |
+        +-----------------+===================+
+
+             +=================+===============+-+-+-+-+
+        ---> | List of Records | Index Padding | CRC32 |
+             +=================+===============+-+-+-+-+
+
+        Index serves several purposes. Using it, one can
+          - verify that all Blocks in a Stream have been processed;
+          - find out the uncompressed size of a Stream; and
+          - quickly access the beginning of any Block (random access).
+
+
+4.1. Index Indicator
+
+        This field overlaps with the Block Header Size field (see
+        Section 3.1.1). The value of Index Indicator is always 0x00.
+
+
+4.2. Number of Records
+
+        This field indicates how many Records there are in the List
+        of Records field, and thus how many Blocks there are in the
+        Stream. The value is stored using the encoding described in
+        Section 1.2. If the decoder has decoded all the Blocks of the
+        Stream, and then notices that the Number of Records doesn't
+        match the real number of Blocks, the decoder MUST indicate an
+        error.
+
+
+4.3. List of Records
+
+        List of Records consists of as many Records as indicated by the
+        Number of Records field:
+
+            +========+========+
+            | Record | Record | ...
+            +========+========+
+
+        Each Record contains information about one Block:
+
+            +===============+===================+
+            | Unpadded Size | Uncompressed Size |
+            +===============+===================+
+
+        If the decoder has decoded all the Blocks of the Stream, it
+        MUST verify that the contents of the Records match the real
+        Unpadded Size and Uncompressed Size of the respective Blocks.
+
+        Implementation hint: It is possible to verify the Index with
+        constant memory usage by calculating for example SHA-256 of
+        both the real size values and the List of Records, then
+        comparing the hash values. Implementing this using
+        non-cryptographic hash like CRC32 SHOULD be avoided unless
+        small code size is important.
+
+        If the decoder supports random-access reading, it MUST verify
+        that Unpadded Size and Uncompressed Size of every completely
+        decoded Block match the sizes stored in the Index. If only
+        partial Block is decoded, the decoder MUST verify that the
+        processed sizes don't exceed the sizes stored in the Index.
+
+
+4.3.1. Unpadded Size
+
+        This field indicates the size of the Block excluding the Block
+        Padding field. That is, Unpadded Size is the size of the Block
+        Header, Compressed Data, and Check fields. Unpadded Size is
+        stored using the encoding described in Section 1.2. The value
+        MUST never be zero; with the current structure of Blocks, the
+        actual minimum value for Unpadded Size is five.
+
+        Implementation note: Because the size of the Block Padding
+        field is not included in Unpadded Size, calculating the total
+        size of a Stream or doing random-access reading requires
+        calculating the actual size of the Blocks by rounding Unpadded
+        Sizes up to the next multiple of four.
+
+        The reason to exclude Block Padding from Unpadded Size is to
+        ease making a raw copy of Compressed Data without Block
+        Padding. This can be useful, for example, if someone wants
+        to convert Streams to some other file format quickly.
+
+
+4.3.2. Uncompressed Size
+
+        This field indicates the Uncompressed Size of the respective
+        Block as bytes. The value is stored using the encoding
+        described in Section 1.2.
+
+
+4.4. Index Padding
+
+        This field MUST contain 0-3 null bytes to pad the Index to
+        a multiple of four bytes. If any of the bytes are not null
+        bytes, the decoder MUST indicate an error.
+
+
+4.5. CRC32
+
+        The CRC32 is calculated over everything in the Index field
+        except the CRC32 field itself. The CRC32 is stored as an
+        unsigned 32-bit little endian integer. If the calculated
+        value does not match the stored one, the decoder MUST indicate
+        an error.
+
+
+5. Filter Chains
+
+        The Block Flags field defines how many filters are used. When
+        more than one filter is used, the filters are chained; that is,
+        the output of one filter is the input of another filter. The
+        following figure illustrates the direction of data flow.
+
+                    v   Uncompressed Data   ^
+                    |       Filter 0        |
+            Encoder |       Filter 1        | Decoder
+                    |       Filter n        |
+                    v    Compressed Data    ^
+
+
+5.1. Alignment
+
+        Alignment of uncompressed input data is usually the job of
+        the application producing the data. For example, to get the
+        best results, an archiver tool should make sure that all
+        PowerPC executable files in the archive stream start at
+        offsets that are multiples of four bytes.
+
+        Some filters, for example LZMA2, can be configured to take
+        advantage of specified alignment of input data. Note that
+        taking advantage of aligned input can be beneficial also when
+        a filter is not the first filter in the chain. For example,
+        if you compress PowerPC executables, you may want to use the
+        PowerPC filter and chain that with the LZMA2 filter. Because
+        not only the input but also the output alignment of the PowerPC
+        filter is four bytes, it is now beneficial to set LZMA2
+        settings so that the LZMA2 encoder can take advantage of its
+        four-byte-aligned input data.
+
+        The output of the last filter in the chain is stored to the
+        Compressed Data field, which is is guaranteed to be aligned
+        to a multiple of four bytes relative to the beginning of the
+        Stream. This can increase
+          - speed, if the filtered data is handled multiple bytes at
+            a time by the filter-specific encoder and decoder,
+            because accessing aligned data in computer memory is
+            usually faster; and
+          - compression ratio, if the output data is later compressed
+            with an external compression tool.
+
+
+5.2. Security
+
+        If filters would be allowed to be chained freely, it would be
+        possible to create malicious files, that would be very slow to
+        decode. Such files could be used to create denial of service
+        attacks.
+
+        Slow files could occur when multiple filters are chained:
+
+            v   Compressed input data
+            |   Filter 1 decoder (last filter)
+            |   Filter 0 decoder (non-last filter)
+            v   Uncompressed output data
+
+        The decoder of the last filter in the chain produces a lot of
+        output from little input. Another filter in the chain takes the
+        output of the last filter, and produces very little output
+        while consuming a lot of input. As a result, a lot of data is
+        moved inside the filter chain, but the filter chain as a whole
+        gets very little work done.
+
+        To prevent this kind of slow files, there are restrictions on
+        how the filters can be chained. These restrictions MUST be
+        taken into account when designing new filters.
+
+        The maximum number of filters in the chain has been limited to
+        four, thus there can be at maximum of three non-last filters.
+        Of these three non-last filters, only two are allowed to change
+        the size of the data.
+
+        The non-last filters, that change the size of the data, MUST
+        have a limit how much the decoder can compress the data: the
+        decoder SHOULD produce at least n bytes of output when the
+        filter is given 2n bytes of input. This  limit is not
+        absolute, but significant deviations MUST be avoided.
+
+        The above limitations guarantee that if the last filter in the
+        chain produces 4n bytes of output, the chain as a whole will
+        produce at least n bytes of output.
+
+
+5.3. Filters
+
+5.3.1. LZMA2
+
+        LZMA (Lempel-Ziv-Markov chain-Algorithm) is a general-purpose
+        compression algorithm with high compression ratio and fast
+        decompression. LZMA is based on LZ77 and range coding
+        algorithms.
+
+        LZMA2 is an extension on top of the original LZMA. LZMA2 uses
+        LZMA internally, but adds support for flushing the encoder,
+        uncompressed chunks, eases stateful decoder implementations,
+        and improves support for multithreading. Thus, the plain LZMA
+        will not be supported in this file format.
+
+            Filter ID:                  0x21
+            Size of Filter Properties:  1 byte
+            Changes size of data:       Yes
+            Allow as a non-last filter: No
+            Allow as the last filter:   Yes
+
+            Preferred alignment:
+                Input data:             Adjustable to 1/2/4/8/16 byte(s)
+                Output data:            1 byte
+
+        The format of the one-byte Filter Properties field is as
+        follows:
+
+            Bits   Mask   Description
+            0-5    0x3F   Dictionary Size
+            6-7    0xC0   Reserved for future use; MUST be zero for now.
+
+        Dictionary Size is encoded with one-bit mantissa and five-bit
+        exponent. The smallest dictionary size is 4 KiB and the biggest
+        is 4 GiB.
+
+            Raw value   Mantissa   Exponent   Dictionary size
+                0           2         11         4 KiB
+                1           3         11         6 KiB
+                2           2         12         8 KiB
+                3           3         12        12 KiB
+                4           2         13        16 KiB
+                5           3         13        24 KiB
+                6           2         14        32 KiB
+              ...         ...        ...      ...
+               35           3         27       768 MiB
+               36           2         28      1024 MiB
+               37           3         29      1536 MiB
+               38           2         30      2048 MiB
+               39           3         30      3072 MiB
+               40           2         31      4096 MiB - 1 B
+
+        Instead of having a table in the decoder, the dictionary size
+        can be decoded using the following C code:
+
+            const uint8_t bits = get_dictionary_flags() & 0x3F;
+            if (bits > 40)
+                return DICTIONARY_TOO_BIG; // Bigger than 4 GiB
+
+            uint32_t dictionary_size;
+            if (bits == 40) {
+                dictionary_size = UINT32_MAX;
+            } else {
+                dictionary_size = 2 | (bits & 1);
+                dictionary_size <<= bits / 2 + 11;
+            }
+
+
+5.3.2. Branch/Call/Jump Filters for Executables
+
+        These filters convert relative branch, call, and jump
+        instructions to their absolute counterparts in executable
+        files. This conversion increases redundancy and thus
+        compression ratio.
+
+            Size of Filter Properties:  0 or 4 bytes
+            Changes size of data:       No
+            Allow as a non-last filter: Yes
+            Allow as the last filter:   No
+
+        Below is the list of filters in this category. The alignment
+        is the same for both input and output data.
+
+            Filter ID   Alignment   Description
+              0x04       1 byte     x86 filter (BCJ)
+              0x05       4 bytes    PowerPC (big endian) filter
+              0x06      16 bytes    IA64 filter
+              0x07       4 bytes    ARM (little endian) filter
+              0x08       2 bytes    ARM Thumb (little endian) filter
+              0x09       4 bytes    SPARC filter
+
+        If the size of Filter Properties is four bytes, the Filter
+        Properties field contains the start offset used for address
+        conversions. It is stored as an unsigned 32-bit little endian
+        integer. The start offset MUST be a multiple of the alignment
+        of the filter as listed in the table above; if it isn't, the
+        decoder MUST indicate an error. If the size of Filter
+        Properties is zero, the start offset is zero.
+
+        Setting the start offset may be useful if an executable has
+        multiple sections, and there are many cross-section calls.
+        Taking advantage of this feature usually requires usage of
+        the Subblock filter, whose design is not complete yet.
+
+
+5.3.3. Delta
+
+        The Delta filter may increase compression ratio when the value
+        of the next byte correlates with the value of an earlier byte
+        at specified distance.
+
+            Filter ID:                  0x03
+            Size of Filter Properties:  1 byte
+            Changes size of data:       No
+            Allow as a non-last filter: Yes
+            Allow as the last filter:   No
+
+            Preferred alignment:
+                Input data:             1 byte
+                Output data:            Same as the original input data
+
+        The Properties byte indicates the delta distance, which can be
+        1-256 bytes backwards from the current byte: 0x00 indicates
+        distance of 1 byte and 0xFF distance of 256 bytes.
+
+
+5.3.3.1. Format of the Encoded Output
+
+        The code below illustrates both encoding and decoding with
+        the Delta filter.
+
+            // Distance is in the range [1, 256].
+            const unsigned int distance = get_properties_byte() + 1;
+            uint8_t pos = 0;
+            uint8_t delta[256];
+
+            memset(delta, 0, sizeof(delta));
+
+            while (1) {
+                const int byte = read_byte();
+                if (byte == EOF)
+                    break;
+
+                uint8_t tmp = delta[(uint8_t)(distance + pos)];
+                if (is_encoder) {
+                    tmp = (uint8_t)(byte) - tmp;
+                    delta[pos] = (uint8_t)(byte);
+                } else {
+                    tmp = (uint8_t)(byte) + tmp;
+                    delta[pos] = tmp;
+                }
+
+                write_byte(tmp);
+                --pos;
+            }
+
+
+5.4. Custom Filter IDs
+
+        If a developer wants to use custom Filter IDs, he has two
+        choices. The first choice is to contact Lasse Collin and ask
+        him to allocate a range of IDs for the developer.
+
+        The second choice is to generate a 40-bit random integer,
+        which the developer can use as his personal Developer ID.
+        To minimize the risk of collisions, Developer ID has to be
+        a randomly generated integer, not manually selected "hex word".
+        The following command, which works on many free operating
+        systems, can be used to generate Developer ID:
+
+            dd if=/dev/urandom bs=5 count=1 | hexdump
+
+        The developer can then use his Developer ID to create unique
+        (well, hopefully unique) Filter IDs.
+
+            Bits    Mask                    Description
+             0-15   0x0000_0000_0000_FFFF   Filter ID
+            16-55   0x00FF_FFFF_FFFF_0000   Developer ID
+            56-62   0x3F00_0000_0000_0000   Static prefix: 0x3F
+
+        The resulting 63-bit integer will use 9 bytes of space when
+        stored using the encoding described in Section 1.2. To get
+        a shorter ID, see the beginning of this Section how to
+        request a custom ID range.
+
+
+5.4.1. Reserved Custom Filter ID Ranges
+
+        Range                       Description

+        0x0002_0000 - 0x0007_FFFF   Reserved to ease .7z compatibility

+
+6. Cyclic Redundancy Checks
+
+        There are several incompatible variations to calculate CRC32
+        and CRC64. For simplicity and clarity, complete examples are

+Building XZ Utils for DOS
+=========================
+
+Introduction
+
+    This document explains how to build XZ Utils for DOS using DJGPP.
+    The resulting binaries should run at least on various DOS versions
+    and under Windows 95/98/98SE/ME.
+
+    This is somewhat experimental and has got very little testing.
+
+    Note: Makefile and config.h are updated only now and then. This
+    means that if you checked out a development version, building for
+    DOS might not work without updating Makefile and config.h first.
+
+
+Getting and Installing DJGPP
+
+    You may use <http://www.delorie.com/djgpp/zip-picker.html> to help
+    deciding what to download. If you are only interested in building
+    XZ Utils, the zip-picker may list files that you don't strictly
+    need. However, using the zip-picker can still be worth it to get a
+    nice short summary of installation instructions (they can be found
+    from readme.1st too).
+
+    For a more manual method, first select a mirror from
+    <http://www.delorie.com/djgpp/getting.html> and go the
+    subdirectory named "current". You need the following files:
+
+        unzip32.exe  (if you don't already have a LFN-capable unzipper)
+        v2/djdev205.zip
+        v2gnu/bnu234b.zip
+        v2gnu/gcc920b.zip
+        v2gnu/mak43b.zip
+        v2misc/csdpmi7b.zip
+
+    If newer versions are available, probably you should try them first.
+    Note that versions older than djdev205.zip aren't supported. Also
+    note that you want csdpmi7b.zip even if you run under Windows or
+    DOSEMU because the XZ Utils Makefile will embed cwsdstub.exe to
+    the resulting xz.exe.
+
+    See the instructions in readme.1st found from djdev205.zip. Here's
+    a short summary, but you should still read readme.1st.
+
+        C:\> mkdir DJGPP
+        C:\> cd DJGPP
+        C:\DJGPP> c:\download\unzip32 c:\download\djdev205.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\bnu234b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\gcc920b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\mak43b.zip
+        C:\DJGPP> c:\download\unzip32 c:\download\csdpmi7b.zip
+
+        C:\DJGPP> set PATH=C:\DJGPP\BIN;%PATH%
+        C:\DJGPP> set DJGPP=C:\DJGPP\DJGPP.ENV
+
+    You may want to add the last two lines into AUTOEXEC.BAT or have,
+    for example, DJGPP.BAT which you can run before using DJGPP.
+
+    Make sure you use completely upper case path in the DJGPP environment
+    variable. This is not required by DJGPP, but the XZ Utils Makefile is
+    a bit stupid and expects that everything in DJGPP environment variable
+    is uppercase.
+
+
+Building
+
+    You need to have an environment that supports long filenames (LFN).
+    Once you have built XZ Utils, the resulting binaries can be run
+    without long filename support.
+
+    Run "make" in this directory (the directory containing this
+    INSTALL.txt). You should get xz.exe (and a bunch of temporary files).
+    Other tools are not built. Having e.g. xzdec.exe doesn't save much
+    space compared to xz.exe because the DJGPP runtime makes the .exe
+    quite big anyway.

+XZ Utils on DOS
+===============
+
+DOS-specific filename handling
+
+    xz detects at runtime if long filename (LFN) support is
+    available and will use it by default. It can be disabled by
+    setting an environment variable:
+
+        set lfn=n
+
+    When xz is in LFN mode, it behaves pretty much the same as it
+    does on other operating systems. Examples:
+
+        xz foo.tar          -> foo.tar.xz
+        xz -d foo.tar.xz    -> foo.tar
+
+        xz -F lzma foo.tar  -> foo.tar.lzma
+        xz -d foo.tar.lzma  -> foo.tar
+
+    When LFN support isn't available or it is disabled with LFN=n
+    environment setting, xz works in short filename (SFN) mode. This
+    affects filename suffix handling when compressing.
+
+    When compressing to the .xz format in SFN mode:
+
+      - Files without an extension get .xz just like on LFN systems.
+
+      - *.tar files become *.txz (shorthand for *.tar.xz). *.txz
+        is recognized by xz on all supported operating systems.
+        (Try to avoid confusing this with gzipped .txt files.)
+
+      - Files with 1-3 character extension have their extension modified
+        so that the last character is a dash ("-"). If the extension
+        is already three characters, the last character is lost. The
+        resulting *.?- or *.??- filename is recognized in LFN mode, but
+        it isn't recognized by xz on other operating systems.
+
+    Examples:
+
+        xz foo              -> foo.xz     |   xz -d foo.xz    -> foo
+        xz foo.tar          -> foo.txz    |   xz -d foo.txz   -> foo.tar
+        xz foo.c            -> foo.c-     |   xz -d foo.c-    -> foo.c
+        xz read.me          -> read.me-   |   xz -d read.me-  -> read.me
+        xz foo.txt          -> foo.tx-    |   xz -d foo.tx-   -> foo.tx   !
+
+    Note that in the last example above, the third character of the
+    filename extension is lost.
+
+    When compressing to the legacy .lzma format in SFN mode:
+
+      - *.tar files become *.tlz (shorthand for *.tar.lzma). *.tlz
+        is recognized by xz on all supported operating systems.
+
+      - Other files become *.lzm. The original filename extension
+        is lost. *.lzm is recognized also in LFN mode, but it is not
+        recognized by xz on other operating systems.
+
+    Examples:
+
+        xz -F lzma foo      -> foo.lzm    |   xz -d foo.lzm   -> foo
+        xz -F lzma foo.tar  -> foo.tlz    |   xz -d foo.tlz   -> foo.tar
+        xz -F lzma foo.c    -> foo.lzm    |   xz -d foo.lzm   -> foo      !
+        xz -F lzma read.me  -> read.lzm   |   xz -d read.lzm  -> read     !
+        xz -F lzma foo.txt  -> foo.lzm    |   xz -d foo.lzm   -> foo      !
+
+    When compressing with a custom suffix (-S .SUF, --suffix=.SUF) to
+    any file format:
+
+      - If the suffix begins with a dot, the filename extension is
+        replaced with the new suffix. The original extension is lost.
+
+      - If the suffix doesn't begin with a dot and the filename has no
+        extension and the filename given on the command line doesn't
+        have a dot at the end, the custom suffix is appended just like
+        on LFN systems.
+
+      - If the suffix doesn't begin with a dot and the filename has
+        an extension (or an extension-less filename is given with a dot
+        at the end), the last 1-3 characters of the filename extension
+        may get overwritten to fit the given custom suffix.
+
+    Examples:
+
+        xz -S x foo        -> foox      |  xz -dS x foox      -> foo
+        xz -S x foo.       -> foo.x     |  xz -dS x foo.x     -> foo
+        xz -S .x foo       -> foo.x     |  xz -dS .x foo.x    -> foo
+        xz -S .x foo.      -> foo.x     |  xz -dS .x foo.x    -> foo
+        xz -S x.y foo      -> foox.y    |  xz -dS x.y foox.y  -> foo
+        xz -S .a foo.c     -> foo.a     |  xz -dS .a foo.a    -> foo      !
+        xz -S a  foo.c     -> foo.ca    |  xz -dS a foo.ca    -> foo.c
+        xz -S ab foo.c     -> foo.cab   |  xz -dS ab foo.cab  -> foo.c
+        xz -S ab read.me   -> read.mab  |  xz -dS ab read.mab -> read.m   !

+
+    When decompressing, the suffix handling in SFN mode is the same as
+    in LFN mode. The DOS-specific filenames *.lzm, *.?-, and *.??- are
+    recognized also in LFN mode.
+
+    xz handles certain uncommon situations safely:
+
+      - If the generated output filename refers to the same file as
+        the input file, xz detects this and refuses to compress or
+        decompress the input file even if --force is used. This can
+        happen when giving an overlong filename in SFN mode. E.g.
+        "xz -S x foo.texinfo" would try to write to foo.tex which on
+        SFN system is the same file as foo.texinfo.
+
+      - If the generated output filename is a special file like "con"
+        or "prn", xz detects this and refuses to compress or decompress
+        the input file even if --force is used.
+
+
+Bugs
+
+    xz doesn't necessarily work in Dosbox. It should work in DOSEMU.
+
+    Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file
+    when running under Windows XP Command Prompt (something goes wrong
+    with SIGINT handling). It works correctly under Windows 95/98/98SE/ME.

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.
+
+   If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT
+   environment variable were set.  */

+# DESCRIPTION
+#
+#   This macro searches for an installed Capsicum header and library,
+#   and if found:
+#     - AC_DEFINE([HAVE_CAPSICUM]) is called.
+#     - AC_DEFINE([HAVE_SYS_CAPSICUM_H]) is called if <sys/capsicum.h>
+#       is present (otherwise <sys/capability.h> must be used).
+#     - CAPSICUM_LIB is set to the -l option needed to link Capsicum support,
+#       and AC_SUBST([CAPSICUM_LIB]) is called.
+#     - The shell commands in ACTION-IF-FOUND are run. The default
+#       ACTION-IF-FOUND prepends ${CAPSICUM_LIB} into LIBS. If you don't
+#       want to modify LIBS and don't need to run any other commands either,
+#       use a colon as ACTION-IF-FOUND.
+#
+#   If Capsicum support isn't found:
+#     - The shell commands in ACTION-IF-NOT-FOUND are run. The default
+#       ACTION-IF-NOT-FOUND calls AC_MSG_WARN to print a warning that
+#       Capsicum support wasn't found.
+#
+#   You should use autoheader to include a definition for the symbols above

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.
