+Authors of XZ Utils
+===================
+
+    XZ Utils is developed and maintained by Lasse Collin
+    <lasse.collin@tukaani.org>.
+
+    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.

+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 <http://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.

+                       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.

+                       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.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+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.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

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

+0. Preface
+----------
+
+    If you aren't familiar with building packages that use GNU Autotools,
+    see the file INSTALL.generic for generic instructions before reading
+    further.
+
+    If you are going to build a package for distribution, see also the
+    file PACKAGERS. It contains information that should help making the
+    binary packages as good as possible, but the information isn't very
+    interesting to those making local builds for private use or for use
+    in special situations like embedded systems.
+
+
+1. Supported platforms
+----------------------
+
+    XZ Utils are developed on GNU/Linux, but they should work on many
+    POSIX-like operating systems like *BSDs and Solaris, and even on
+    a few non-POSIX operating systems.
+
+
+1.1. Compilers
+
+    A C99 compiler is required to compile XZ Utils. If you use GCC, you
+    need at least version 3.x.x. GCC version 2.xx.x doesn't support some
+    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). 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
+
+    Building XZ Utils on Windows is supported under the following
+    environments:
+
+      - 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".
+
+      - Microsoft Visual Studio 2013 update 2 or later (MSVC for short):
+        See windows/INSTALL-MSVC.txt for more information.
+
+    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 an experimental Makefile in the "dos" directory to build
+    XZ Utils on DOS using DJGPP. Support for long file names (LFN) is
+    needed. See dos/README for more information.
+
+    GNU Autotools based build hasn't been tried on DOS. If you try, I
+    would like to hear if it worked.
+
+
+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.
+
+    --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-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.
+
+
+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 scripts assume that the required tools (standard POSIX utilities,
+    mktemp, and xz) are in PATH; the scripts don't set the PATH themselves.
+    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. One fix
+    for this problem is 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 commands `./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.
+
+   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 bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /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.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+XZ Utils Release Notes
+======================
+
+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

+0. Overview
+-----------
 
-Tcl/Tk release and mailing list services are hosted by SourceForge:
+    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.
 
-	http://sourceforge.net/projects/tcl/
+    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.
 
-with the Tcl Developer Xchange hosted at:
+    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.
 
-	http://www.tcl.tk/
+    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.
 
-Tcl is a freely available open source package.  You can do virtually
-anything you like with it, such as modifying it, redistributing it,
-and selling it either in whole or in part.  See the file
-"license.terms" for complete information.
+    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.
 
-2. Documentation
+    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 doesn't support multithreaded compression or decompression
+    yet. It has been planned though and taken into account when designing
+    the .xz file format.

-2a. Unix Documentation
+    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.
+
+    I have planned to write a bunch of very well documented example
+    programs, which (due to comments) should work as a tutorial to
+    various features of liblzma. No such example programs have been
+    written yet.
+
+    For now, if you have never used liblzma, libbzip2, or zlib, I
+    recommend learning the *basics* of the zlib API. Once you know that,
+    it should be easier to learn liblzma.
+
+        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. Translating the xz tool
+--------------------------
+
+    The messages from the xz tool have been translated into a few
+    languages. Before starting to translate into a new language, ask
+    the author whether someone else hasn't already started working on it.
+
+    Test your translation. Testing includes comparing the translated
+    output to the original English version by running the same commands
+    in both your target locale and with LC_ALL=C. Ask someone to
+    proof-read and test the translation.
+
+    Testing can be done e.g. 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. If they suggest testing the
+        translation with some type of command, do it. If testing needs
+        input files, use e.g. tests/files/good-*.xz.
+
+      - When updating the translation, read the fuzzy (modified) strings
+        carefully, and don't mark them as updated before you actually
+        have updated them. Reading through the unchanged messages can be
+        good too; sometimes you may find a better wording for them.
+
+      - 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.
+
+    In short, take your time and pay attention to the details. Making
+    a good translation is not a quick and trivial thing to do. The
+    translated xz should look as polished as the English version.
+
+
+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.

-		ditroff -man Tcl.n
+    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.
 
-to print Tcl.n.  If Tcl has been installed correctly and your "man" program
-supports it, you should be able to access the Tcl manual entries using the
-normal "man" mechanisms, such as
-
-		man Tcl
-
-2b. Windows Documentation
--------------------------
-
-The "doc" subdirectory in this release contains a complete set of Windows
-help files for Tcl.  Once you install this Tcl release, a shortcut to the
-Windows help Tcl documentation will appear in the "Start" menu:
-
-	Start | Programs | Tcl | Tcl Help
-
-3. Compiling and installing Tcl
--------------------------------
-
-There are brief notes in the unix/README, win/README, and macosx/README about
-compiling on these different platforms.  There is additional information
-about building Tcl from sources at
-
-	http://www.tcl.tk/doc/howto/compile.html
-
-4. Development tools
----------------------------
-
-ActiveState produces a high quality set of commercial quality development
-tools that is available to accelerate your Tcl application development.
-Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,
-static code checker, single-file wrapping utility, bytecode compiler and

-	http://www.ActiveState.com/Tcl
-
-5. Tcl newsgroup
-----------------
-
-There is a USENET news group, "comp.lang.tcl", intended for the exchange of
-information about Tcl, Tk, and related applications.  The newsgroup is a
-great place to ask general information questions.  For bug reports, please
-see the "Support and bug fixes" section below.
-
-6. Tcl'ers Wiki
----------------
-
-A Wiki-based open community site covering all aspects of Tcl/Tk is at:
-
-	http://wiki.tcl.tk/
-
-It is dedicated to the Tcl programming language and its extensions.  A
-wealth of useful information can be found there.  It contains code
-snippets, references to papers, books, and FAQs, as well as pointers to
-development tools, extensions, and applications.  You can also recommend
-additional URLs by editing the wiki yourself.
-
-7. Mailing lists
-----------------
-
-Several mailing lists are hosted at SourceForge to discuss development or

-8. Support and Training
-------------------------
-
-We are very interested in receiving bug reports, patches, and suggestions
-for improvements.  We prefer that you send this information to us as
-tickets entered into our tracker at:
-
-	http://core.tcl.tk/tcl/reportlist
-
-We will log and follow-up on each bug, although we cannot promise a
-specific turn-around time.  Enhancements may take longer and may not happen
-at all unless there is widespread support for them (we're trying to
-slow the rate at which Tcl/Tk turns into a kitchen sink).  It's very
-difficult to make incompatible changes to Tcl/Tk at this point, due to
-the size of the installed base.
-
-The Tcl community is too large for us to provide much individual support
-for users.  If you need help we suggest that you post questions to
-comp.lang.tcl.  We read the newsgroup and will attempt to answer esoteric
-questions for which no one else is likely to know the answer.  In addition,
-see the following Web site for links to other organizations that offer
-Tcl/Tk training:
-
-	http://wiki.tcl.tk/training
-
-9. Tracking Development
------------------------
-

+
+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.

+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory

-
-                Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://zlib.net/ which may have more recent information.
-The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
-    Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
-    The zlib sources can be compiled without change to produce a DLL.  See the
-    file win32/DLL_FAQ.txt in the zlib distribution.  Pointers to the
-    precompiled DLL are found in the zlib web site at http://zlib.net/ .
-
- 3. Where can I get a Visual Basic interface to zlib?
-
-    See
-        * http://marknelson.us/1997/01/01/zlib-engine/
-        * win32/DLL_FAQ.txt in the zlib distribution
-
- 4. compress() returns Z_BUF_ERROR.
-
-    Make sure that before the call of compress(), the length of the compressed
-    buffer is equal to the available size of the compressed buffer and not
-    zero.  For Visual Basic, check that this parameter is passed by reference
-    ("as any"), not by value ("as long").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR.
-
-    Before making the call, make sure that avail_in and avail_out are not zero.
-    When setting the parameter flush equal to Z_FINISH, also make sure that
-    avail_out is big enough to allow processing all pending input.  Note that a
-    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
-    made with more input or output space.  A Z_BUF_ERROR may in fact be
-    unavoidable depending on how the functions are used, since it is not
-    possible to tell whether or not there is more output pending when
-    strm.avail_out returns with zero.  See http://zlib.net/zlib_how.html for a
-    heavily annotated example.
-
- 6. Where's the zlib documentation (man pages, etc.)?
-
-    It's in zlib.h .  Examples of zlib usage are in the files test/example.c
-    and test/minigzip.c, with more in examples/ .
-
- 7. Why don't you use GNU autoconf or libtool or ...?
-
-    Because we would like to keep zlib as a very small and simple package.
-    zlib is rather portable and doesn't need much configuration.
-
- 8. I found a bug in zlib.
-
-    Most of the time, such problems are due to an incorrect usage of zlib.
-    Please try to reproduce the problem with a small program and send the
-    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
-    data files without prior agreement.
-
- 9. Why do I get "undefined reference to gzputc"?
-
-    If "make test" produces something like
-
-       example.o(.text+0x154): undefined reference to `gzputc'
-
-    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
-    /usr/X11R6/lib. Remove any old versions, then do "make install".
-
-10. I need a Delphi interface to zlib.
-
-    See the contrib/delphi directory in the zlib distribution.
-
-11. Can zlib handle .zip archives?
-
-    Not by itself, no.  See the directory contrib/minizip in the zlib
-    distribution.
-
-12. Can zlib handle .Z files?
-
-    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
-    the code of uncompress on your own.
-
-13. How can I make a Unix shared library?
-
-    By default a shared (and a static) library is built for Unix.  So:
-
-    make distclean
-    ./configure
-    make
-
-14. How do I install a shared zlib library on Unix?
-
-    After the above, then:
-
-    make install
-
-    However, many flavors of Unix come with a shared zlib already installed.
-    Before going to the trouble of compiling a shared version of zlib and
-    trying to install it, you may want to check if it's already there!  If you
-    can #include <zlib.h>, it's there.  The -lz option will probably link to
-    it.  You can check the version at the top of zlib.h or with the
-    ZLIB_VERSION symbol defined in zlib.h .
-
-15. I have a question about OttoPDF.
-
-    We are not the authors of OttoPDF. The real author is on the OttoPDF web
-    site: Joel Hainley, jhainley@myndkryme.com.
-
-16. Can zlib decode Flate data in an Adobe PDF file?
-
-    Yes. See http://www.pdflib.com/ . To modify PDF forms, see
-    http://sourceforge.net/projects/acroformtool/ .
-
-17. Why am I getting this "register_frame_info not found" error on Solaris?
-
-    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
-    generates an error such as:
-
-        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
-        symbol __register_frame_info: referenced symbol not found
-
-    The symbol __register_frame_info is not part of zlib, it is generated by
-    the C compiler (cc or gcc).  You must recompile applications using zlib
-    which have this problem.  This problem is specific to Solaris.  See
-    http://www.sunfreeware.com for Solaris versions of zlib and applications
-    using zlib.
-
-18. Why does gzip give an error on a file I make with compress/deflate?
-
-    The compress and deflate functions produce data in the zlib format, which
-    is different and incompatible with the gzip format.  The gz* functions in
-    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
-    use the same compressed data format internally, but have different headers
-    and trailers around the compressed data.
-
-19. Ok, so why are there two different formats?
-
-    The gzip format was designed to retain the directory information about a
-    single file, such as the name and last modification date.  The zlib format
-    on the other hand was designed for in-memory and communication channel
-    applications, and has a much more compact header and trailer and uses a
-    faster integrity check than gzip.
-
-20. Well that's nice, but how do I make a gzip file in memory?
-
-    You can request that deflate write the gzip format instead of the zlib
-    format using deflateInit2().  You can also request that inflate decode the
-    gzip format using inflateInit2().  Read zlib.h for more details.
-
-21. Is zlib thread-safe?
-
-    Yes.  However any library routines that zlib uses and any application-
-    provided memory allocation routines must also be thread-safe.  zlib's gz*
-    functions use stdio library routines, and most of zlib's functions use the
-    library memory allocation routines by default.  zlib's *Init* functions
-    allow for the application to provide custom memory allocation routines.
-
-    Of course, you should only operate on any given zlib or gzip stream from a
-    single thread at a time.
-
-22. Can I use zlib in my commercial application?
-
-    Yes.  Please read the license in zlib.h.
-
-23. Is zlib under the GNU license?
-
-    No.  Please read the license in zlib.h.
-
-24. The license says that altered source versions must be "plainly marked". So
-    what exactly do I need to do to meet that requirement?
-
-    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
-    particular, the final version number needs to be changed to "f", and an
-    identification string should be appended to ZLIB_VERSION.  Version numbers
-    x.x.x.f are reserved for modifications to zlib by others than the zlib
-    maintainers.  For example, if the version of the base zlib you are altering
-    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
-    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
-    update the version strings in deflate.c and inftrees.c.
-
-    For altered source distributions, you should also note the origin and
-    nature of the changes in zlib.h, as well as in ChangeLog and README, along
-    with the dates of the alterations.  The origin should include at least your
-    name (or your company's name), and an email address to contact for help or
-    issues with the library.
-
-    Note that distributing a compiled zlib library along with zlib.h and
-    zconf.h is also a source distribution, and so you should change
-    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
-    in zlib.h as you would for a full source distribution.
-
-25. Will zlib work on a big-endian or little-endian architecture, and can I
-    exchange compressed data between them?
-
-    Yes and yes.
-
-26. Will zlib work on a 64-bit machine?
-
-    Yes.  It has been tested on 64-bit machines, and has no dependence on any
-    data types being limited to 32-bits in length.  If you have any
-    difficulties, please provide a complete problem report to zlib@gzip.org
-
-27. Will zlib decompress data from the PKWare Data Compression Library?
-
-    No.  The PKWare DCL uses a completely different compressed data format than
-    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
-    directory for a possible solution to your problem.
-
-28. Can I access data randomly in a compressed stream?
-
-    No, not without some preparation.  If when compressing you periodically use
-    Z_FULL_FLUSH, carefully write all the pending data at those points, and
-    keep an index of those locations, then you can start decompression at those
-    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
-    can significantly degrade compression.  Alternatively, you can scan a
-    deflate stream once to generate an index, and then use that index for
-    random access.  See examples/zran.c .
-
-29. Does zlib work on MVS, OS/390, CICS, etc.?
-
-    It has in the past, but we have not heard of any recent evidence.  There
-    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
-    If you know of recent, successful applications of zlib on these operating
-    systems, please let us know.  Thanks.
-
-30. Is there some simpler, easier to read version of inflate I can look at to
-    understand the deflate format?
-
-    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
-    contrib/puff directory.
-
-31. Does zlib infringe on any patents?
-
-    As far as we know, no.  In fact, that was originally the whole point behind
-    zlib.  Look here for some more information:
-
-    http://www.gzip.org/#faq11
-
-32. Can zlib work with greater than 4 GB of data?
-
-    Yes.  inflate() and deflate() will process any amount of data correctly.
-    Each call of inflate() or deflate() is limited to input and output chunks
-    of the maximum value that can be stored in the compiler's "unsigned int"
-    type, but there is no limit to the number of chunks.  Note however that the
-    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
-    counters are provided as a convenience and are not used internally by
-    inflate() or deflate().  The application can easily set up its own counters
-    updated after each call of inflate() or deflate() to count beyond 4 GB.
-    compress() and uncompress() may be limited to 4 GB, since they operate in a
-    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
-    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
-
-    The word "may" appears several times above since there is a 4 GB limit only
-    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
-    64 bits, then the limit is 16 exabytes.
-
-33. Does zlib have any security vulnerabilities?
-
-    The only one that we are aware of is potentially in gzprintf().  If zlib is
-    compiled to use sprintf() or vsprintf(), then there is no protection
-    against a buffer overflow of an 8K string space (or other value as set by
-    gzbuffer()), other than the caller of gzprintf() assuring that the output
-    will not exceed 8K.  On the other hand, if zlib is compiled to use
-    snprintf() or vsnprintf(), which should normally be the case, then there is
-    no vulnerability.  The ./configure script will display warnings if an
-    insecure variation of sprintf() will be used by gzprintf().  Also the
-    zlibCompileFlags() function will return information on what variant of
-    sprintf() is used by gzprintf().
-
-    If you don't have snprintf() or vsnprintf() and would like one, you can
-    find a portable implementation here:
-
-        http://www.ijs.si/software/snprintf/
-
-    Note that you should be using the most recent version of zlib.  Versions
-    1.1.3 and before were subject to a double-free vulnerability, and versions
-    1.2.1 and 1.2.2 were subject to an access exception when decompressing
-    invalid compressed data.
-
-34. Is there a Java version of zlib?
-
-    Probably what you want is to use zlib in Java. zlib is already included
-    as part of the Java SDK in the java.util.zip package. If you really want
-    a version of zlib written in the Java language, look on the zlib home
-    page for links: http://zlib.net/ .
-
-35. I get this or that compiler or source-code scanner warning when I crank it
-    up to maximally-pedantic. Can't you guys write proper code?
-
-    Many years ago, we gave up attempting to avoid warnings on every compiler
-    in the universe.  It just got to be a waste of time, and some compilers
-    were downright silly as well as contradicted each other.  So now, we simply
-    make sure that the code always works.
-
-36. Valgrind (or some similar memory access checker) says that deflate is
-    performing a conditional jump that depends on an uninitialized value.
-    Isn't that a bug?
-
-    No.  That is intentional for performance reasons, and the output of deflate
-    is not affected.  This only started showing up recently since zlib 1.2.x
-    uses malloc() by default for allocations, whereas earlier versions used
-    calloc(), which zeros out the allocated memory.  Even though the code was
-    correct, versions 1.2.4 and later was changed to not stimulate these
-    checkers.
-
-37. Will zlib read the (insert any ancient or arcane format here) compressed
-    data format?
-
-    Probably not. Look in the comp.compression FAQ for pointers to various
-    formats and associated software.
-
-38. How can I encrypt/decrypt zip files with zlib?
-
-    zlib doesn't support encryption.  The original PKZIP encryption is very
-    weak and can be broken with freely available programs.  To get strong
-    encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
-    compression.  For PKZIP compatible "encryption", look at
-    http://www.info-zip.org/
-
-39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
-
-    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
-    probably have called the second one "zlib" instead to avoid confusion with
-    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
-    correctly points to the zlib specification in RFC 1950 for the "deflate"
-    transfer encoding, there have been reports of servers and browsers that
-    incorrectly produce or expect raw deflate data per the deflate
-    specification in RFC 1951, most notably Microsoft.  So even though the
-    "deflate" transfer encoding using the zlib format would be the more
-    efficient approach (and in fact exactly what the zlib format was designed
-    for), using the "gzip" transfer encoding is probably more reliable due to
-    an unfortunate choice of name on the part of the HTTP 1.1 authors.
-
-    Bottom line: use the gzip format for HTTP 1.1 encoding.
-
-40. Does zlib support the new "Deflate64" format introduced by PKWare?
-
-    No.  PKWare has apparently decided to keep that format proprietary, since
-    they have not documented it as they have previous compression formats.  In
-    any case, the compression improvements are so modest compared to other more
-    modern approaches, that it's not worth the effort to implement.
-
-41. I'm having a problem with the zip functions in zlib, can you help?
-
-    There are no zip functions in zlib.  You are probably using minizip by
-    Giles Vollant, which is found in the contrib directory of zlib.  It is not
-    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
-    files in there are not supported by the zlib authors.  You need to contact
-    the authors of the respective contribution for help.
-
-42. The match.asm code in contrib is under the GNU General Public License.
-    Since it's part of zlib, doesn't that mean that all of zlib falls under the
-    GNU GPL?
-
-    No.  The files in contrib are not part of zlib.  They were contributed by
-    other authors and are provided as a convenience to the user within the zlib
-    distribution.  Each item in contrib has its own license.
-
-43. Is zlib subject to export controls?  What is its ECCN?
-
-    zlib is not subject to export controls, and so is classified as EAR99.
-
-44. Can you please sign these lengthy legal documents and fax them back to us
-    so that we can use your software in our product?
-
-    No. Go away. Shoo.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.8 is a general purpose data compression library.  All the code is
-thread safe.  The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
-rfc1952 (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example
-of the library is given in the file test/example.c which also tests that
-the library is working correctly.  Another example is given in the file
-test/minigzip.c.  The compression library itself is composed of all source
-files in the root directory.
-
-To compile all files and run the test program, follow the instructions given at
-the top of Makefile.in.  In short "./configure; make test", and if that goes
-well, "make install" should work for most flavors of Unix.  For Windows, use
-one of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
-make_vms.com.
-
-Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
-<info@winimage.com> for the Windows DLL version.  The zlib home page is
-http://zlib.net/ .  Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
-
-Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
-issue of Dr.  Dobb's Journal; a copy of the article is available at
-http://marknelson.us/1997/01/01/zlib-engine/ .
-
-The changes made in version 1.2.8 are documented in the file ChangeLog.
-
-Unsupported third party contributions are provided in directory contrib/ .
-
-zlib is available in Java using the java.util.zip package, documented at
-http://java.sun.com/developer/technicalArticles/Programming/compression/ .
-
-A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
-at CPAN (Comprehensive Perl Archive Network) sites, including
-http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
-
-A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
-available in Python 1.5 and later versions, see
-http://docs.python.org/library/zlib.html .
-
-zlib is built into tcl: http://wiki.tcl.tk/4610 .
-
-An experimental package to read and write files in .zip format, written on top
-of zlib by Gilles Vollant <info@winimage.com>, is available in the
-contrib/minizip directory of zlib.
-
-
-Notes for some targets:
-
-- For Windows DLL versions, please see win32/DLL_FAQ.txt
-
-- For 64-bit Irix, deflate.c must be compiled without any optimization. With
-  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
-  compiler flag). The compiler bug has been reported to SGI.
-
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
-  when compiled with cc.
-
-- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
-  necessary to get gzprintf working correctly. This is done by configure.
-
-- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
-  other compilers. Use "make test" to check your compiler.
-
-- gzdopen is not supported on RISCOS or BEOS.
-
-- For PalmOs, see http://palmzlib.sourceforge.net/
-

-Acknowledgments:
-
-  The deflate format used by zlib was defined by Phil Katz.  The deflate and
-  zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
-  people who reported problems and suggested various improvements in zlib; they
-  are too numerous to cite here.

-        ZLIB version 1.2.8 for AS400 installation instructions
-
-I) From an AS400 *SAVF file:
-
-1)      Unpacking archive to an AS400 save file
-
-On the AS400:
-
-_       Create the ZLIB AS400 library:
-
-        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
-
-_       Create a work save file, for example:
-
-                CRTSAVF FILE(ZLIB/ZLIBSAVF)
-
-On a PC connected to the target AS400:
-
-_       Unpack the save file image to a PC file "ZLIBSAVF"
-_       Upload this file into the save file on the AS400, for example
-                using ftp in BINARY mode.
-
-
-2)      Populating the ZLIB AS400 source library
-
-On the AS400:
-
-_       Extract the saved objects into the ZLIB AS400 library using:
-
-RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
-
-
-3)      Customize installation:
-
-_       Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
-                according to the comments.
-
-_       Compile this member with:
-
-        CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
-
-
-4)      Compile and generate the service program:
-
-_       This can now be done by executing:
-
-        CALL PGM(ZLIB/COMPILE)
-
-
-
-II) From the original source distribution:
-
-1)      On the AS400, create the source library:
-
-        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
-
-2)      Create the source files:
-
-        CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
-        CRTSRCPF FILE(ZLIB/H)       RCDLEN(112) TEXT('ZLIB library includes')
-        CRTSRCPF FILE(ZLIB/TOOLS)   RCDLEN(112) TEXT('ZLIB library control utilities')
-
-3)      From the machine hosting the distribution files, upload them (with
-                FTP in text mode, for example) according to the following table:

-Notes:  For AS400 ILE RPG programmers, a /copy member defining the ZLIB
-                API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
-                Please read comments in this member for more information.
-
-        Remember that most foreign textual data are ASCII coded: this
-                implementation does not handle conversion from/to ASCII, so
-                text data code conversions must be done explicitely.
-
-        Mainly for the reason above, always open zipped files in binary mode.

-# Normally configure builds both a static and a shared library.
-# If you want to build just a static library, use: ./configure --static
-#
-# To impose specific compiler or flags or install directory, use for example:
-#    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
-# or for csh/tcsh users:
-#    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
-
-# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
-# If you have problems, try without defining CC and CFLAGS before reporting
-# an error.

-                        ZLib for Ada thick binding (ZLib.Ada)
-                        Release 1.3
-
-ZLib.Ada is a thick binding interface to the popular ZLib data
-compression library, available at http://www.gzip.org/zlib/.
-It provides Ada-style access to the ZLib C library.
-
-
-        Here are the main changes since ZLib.Ada 1.2:
-
-- Attension: ZLib.Read generic routine have a initialization requirement
-  for Read_Last parameter now. It is a bit incompartible with previous version,
-  but extends functionality, we could use new parameters Allow_Read_Some and
-  Flush now.
-
-- Added Is_Open routines to ZLib and ZLib.Streams packages.
-
-- Add pragma Assert to check Stream_Element is 8 bit.
-
-- Fix extraction to buffer with exact known decompressed size. Error reported by
-  Steve Sangwine.
-
-- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
-  computers. Patch provided by Pascal Obry.
-
-- Add Status_Error exception definition.
-
-- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
-
-
-        How to build ZLib.Ada under GNAT
-
-You should have the ZLib library already build on your computer, before
-building ZLib.Ada. Make the directory of ZLib.Ada sources current and
-issue the command:
-
-  gnatmake test -largs -L<directory where libz.a is> -lz
-
-Or use the GNAT project file build for GNAT 3.15 or later:
-
-  gnatmake -Pzlib.gpr -L<directory where libz.a is>
-
-
-        How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
-
-1. Make a project with all *.ads and *.adb files from the distribution.
-2. Build the libz.a library from the ZLib C sources.
-3. Rename libz.a to z.lib.
-4. Add the library z.lib to the project.
-5. Add the libc.lib library from the ObjectAda distribution to the project.
-6. Build the executable using test.adb as a main procedure.
-
-
-        How to use ZLib.Ada
-
-The source files test.adb and read.adb are small demo programs that show
-the main functionality of ZLib.Ada.
-
-The routines from the package specifications are commented.

-This is a patched version of zlib, modified to use
-Pentium-Pro-optimized assembly code in the deflation algorithm. The
-files changed/added by this patch are:
-
-README.686
-match.S
-
-The speedup that this patch provides varies, depending on whether the
-compiler used to build the original version of zlib falls afoul of the
-PPro's speed traps. My own tests show a speedup of around 10-20% at
-the default compression level, and 20-30% using -9, against a version
-compiled using gcc 2.7.2.3. Your mileage may vary.
-
-Note that this code has been tailored for the PPro/PII in particular,
-and will not perform particuarly well on a Pentium.
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

-
-Added for zlib 1.1.3:
-
-The patches come from
-http://www.muppetlabs.com/~breadbox/software/assembly.html
-
-To compile zlib with this asm file, copy match.S to the zlib directory
-then do:
-
-CFLAGS="-O3 -DASMV" ./configure
-make OBJA=match.o
-
-
-Update:
-
-I've been ignoring these assembly routines for years, believing that
-gcc's generated code had caught up with it sometime around gcc 2.95
-and the major rearchitecting of the Pentium 4. However, I recently
-learned that, despite what I believed, this code still has some life
-in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
-faster than the code produced by gcc 4.1.
-
-In acknowledgement of its continuing usefulness, I've altered the
-license to match that of the rest of zlib. Share and Enjoy!

- *
- * - The first code for the shortest length is all ones.  Subsequent codes of
- *   the same length are simply integer decrements of the previous code.  When
- *   moving up a length, a one bit is appended to the code.  For a complete
- *   code, the last code of the longest length will be all zeros.  To support
- *   this ordering, the bits pulled during decoding are inverted to apply the

- * Decode PKWare Compression Library stream.

- * Format notes:
- *
- * - First byte is 0 if literals are uncoded or 1 if they are coded.  Second
- *   byte is 4, 5, or 6 for the number of extra bits in the distance code.
- *   This is the base-2 logarithm of the dictionary size minus six.
- *
- * - Compressed data is a combination of literals and length/distance pairs
- *   terminated by an end code.  Literals are either Huffman coded or
- *   uncoded bytes.  A length/distance pair is a coded length followed by a
- *   coded distance to represent a string that occurs earlier in the
- *   uncompressed data that occurs again at the current location.
- *
- * - A bit preceding a literal or length/distance pair indicates which comes
- *   next, 0 for literals, 1 for length/distance.
- *
- * - If literals are uncoded, then the next eight bits are the literal, in the
- *   normal bit order in th stream, i.e. no bit-reversal is needed. Similarly,
- *   no bit reversal is needed for either the length extra bits or the distance
- *   extra bits.
- *
- * - Literal bytes are simply written to the output.  A length/distance pair is
- *   an instruction to copy previously uncompressed bytes to the output.  The
- *   copy is from distance bytes back in the output stream, copying for length
- *   bytes.
- *
- * - Distances pointing before the beginning of the output data are not
- *   permitted.
- *
- * - Overlapped copies, where the length is greater than the distance, are
- *   allowed and common.  For example, a distance of one and a length of 518
- *   simply copies the last byte 518 times.  A distance of four and a length of
- *   twelve copies the last four bytes three times.  A simple forward copy
- *   ignoring whether the length is greater than the distance or not implements
- *   this correctly.

-
-  TCompressionStream is write-only and strictly sequential. Reading from the
-  stream will raise an exception. Using Seek to move the stream pointer
-  will raise an exception.
-
-  Output data is cached internally, written to the output stream only when
-  the internal output buffer is full.  All pending output data is flushed
-  when the stream is destroyed.
-
-  The Position property returns the number of uncompressed bytes of
-  data that have been written to the stream so far.
-
-  CompressionRate returns the on-the-fly percentage by which the original
-  data has been compressed:  (1 - (CompressedBytes / UncompressedBytes)) * 100

-  is 75%

-  Compressed data comes from a separate source stream.  TDecompressionStream

-  backwards.  The special case of setting the stream position to zero is
-  allowed.  Seeking forward decompresses data until the requested position in
-  the uncompressed data has been reached.  Seeking backwards, seeking relative
-  to the end of the stream, requesting the size of the stream, and writing to
-  the stream will raise an exception.
-
-  The Position property returns the number of bytes of uncompressed data that
-  have been read from the stream so far.
-
-  The OnProgress event is called each time the internal input buffer of
-  compressed data is exhausted and the next block is read from the input stream.
