GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

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

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.

LZMA Utils
----------
Warning
This is an early alpha version. Don't trust the files produced by
this version of the software - not even if the software can
uncompress the files properly! This is because the file format
isn't completely frozen yet.
So please test a lot, but don't use for anything serious yet.
Overview
LZMA is a general purporse compression algorithm designed by
Igor Pavlov as part of 7-Zip. It provides high compression ratio
while keeping the decompression speed fast.
LZMA Utils are an attempt to make LZMA compression easy to use
on free (as in freedom) operating systems. This is achieved by
providing tools and libraries which are similar to use than the
equivalents of the most popular existing compression algorithms.
LZMA Utils consist of a few relatively separate parts:
* liblzma is an encoder/decoder library with support for several
filters (algorithm implementations). The primary filter is LZMA.
* libzfile enables reading from and writing to gzip, bzip2 and
LZMA compressed and uncompressed files with an API similar to
the standard ANSI-C file I/O.
[ NOTE: libzfile is not implemented yet. ]
* lzma command line tool has almost identical syntax than gzip
and bzip2. It makes LZMA easy for average users, but also
provides advanced options to finetune the compression settings.
* A few shell scripts make diffing and grepping LZMA compressed
files easy. The scripts were adapted from gzip and bzip2.
Supported platforms
LZMA Utils are developed on GNU+Linux, but they should work at
least on *BSDs and Solaris. They probably work on some other
POSIX-like operating systems too.
If you use GCC to compile LZMA Utils, you need at least version
3.x.x. GCC version 2.xx.x doesn't support some C99 features used
in LZMA Utils source code, thus GCC 2 won't compile LZMA Utils.
If you have written patches to make LZMA 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++.
configure options
If you are not familiar with `configure' scripts, read the file
INSTALL first.
In most cases, the default --enable/--disable/--with/--without options
are what you want. Don't touch them if you are unsure.
--disable-encoder
Do not compile the encoder component of liblzma. This
implies --disable-match-finders. If you need only
the decoder, you can decrease the library size
dramatically with this option.
The default is to build the encoder.
--disable-decoder
Do not compile the decoder component of liblzma.
The default is to build the decoder.
--enable-filters=
liblzma supports several filters. See liblzma-intro.txt
for a little more information about these.
The default is to build all the filters.
--enable-match-finders=
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
LZMA filter encoder. 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.
--enable-checks=
liblzma support multiple integrity checks. CRC32 is
mandatory, and cannot be omitted. See liblzma-intro.txt
for more information about usage of the integrity checks.
--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.
--enable-small
Omits precomputed tables. This makes liblzma a few KiB
smaller. Startup time increases, because the tables need
to be computed first.
--enable-debug
This enables the assert() macro and possibly some other
run-time consistency checks. It slows down things somewhat,
so you normally don't want to have this enabled.
--enable-werror
Makes 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.
Static vs. dynamic linking of the command line tools
By default, the command line tools are linked statically against
liblzma. There a are a few reasons:
- The executable(s) can be in /bin while the shared liblzma can still
be in /usr/lib (if the distro uses such file system hierachy).
- It's easier to copy the executables to other systems, since they
depend only on libc.
- It's slightly faster on some architectures like x86.
If you don't like this, you can get the command line tools linked
against the shared liblzma by specifying --disable-static to configure.
This disables building static liblzma completely.

LZMA Utils TODO List
--------------------
Major missing features
Memory limits in the command line tool apply only to compression.
Threading support in the lzma command line tool is still primitive.
It cannot split a file in pieces yet.
The --list mode isn't implemented in the command line tool.
Handling of Multi-Block Stream information should be separated
from Stream encoder and decoder. Those would be useful to implement
multi-threaded coding in applications.
Buffer to buffer coding is not implemented in liblzma. Probably
a naive version should be written first, which would simply wrap
things around lzma_stream. Later, there should be separate buffer
coding functions, that are slightly faster (less memcpy()) and
have smaller memory usage than the functions using lzma_stream.
libzfile is not implemented.
LZMA filter doesn't support predefined history buffer.
Security
Search for bugs, especially security related issues. Security is
important in every piece of code in LZMA Utils, but it is extremely
important in the decoder part of liblzma.
Subblock: If there is LZMA as a Subfilter but without EOPM, can it
trigger infinite loop when Subblock's "Unset Subfilter" flag is hit?
Similarly, can LZ decoder get stuck in infinite loop if the next
filter in the chain returns LZMA_STREAM_END but the decoded data
doesn't allow finishing the LZ decoding?
Reliability
Create a test suite to be run with "make check".
Should we use strlimit() and getrlimit() for memory usage limitting?
Performance
Benchmark the CRC code on non-x86 CPUs. Won't have huge effect on
overall speed, but it would still be nice to know what algorithm
variant is the best on different CPUs.
Third party support
Add support for LZMA to various applications. This naturally requires
cooperating with the authors of the specific applications.
* GNU grep and GNU diffutils: BSD grep already uses zlib directly
instead of ugly shell scripts. It would be nice to get similar
feature into relevant GNU tools. With libzfile, multiple
compression formats would be easy to support.
* kioslave for KDE
* Magic for the `file' command
* GNU Midnight Commander
* GNU Texinfo
* The `man' command
* Package managers
Test the patches already written. The patches should be sent to
upstream developers _once_ LZMA Utils APIs are stable enough (so
people don't need to fix those patches all the time).
Mandriva has quite a few patches. Some of them are OK, some need
adapting for new LZMA Utils.
Documentation
Revise the man page of lzma command line tool.
If the Doxygen docs aren't enough, write good Texinfo manual for
liblzma. It's been a long time I've even tried to build the Doxygen
docs, so they may look quite bad at the moment.
Document LZMA as an algorithm. It would be great to have detailed
description of the algorithm in English. Many people think, that
reading the source code is not the optimal way to learn how LZMA
works.
Other
Some things return LZMA_PROG_ERROR with invalid options, some
LZMA_HEADER_ERROR. These must be checked carefully and made so
that LZMA_HEADER_ERROR is used only when the given option could
make sense in future version of libzma.
lzma_restrict vs. restrict
Usage of LZMA_RUN vs. LZMA_FINISH with Metadata coders.
Port the Deflate implementation from 7-Zip into liblzma. 7-Zip's
Deflate compresses better than zlib, gzip or Info-ZIP. I don't
know if Deflate will be included in .lzma format (probably not),
but it's still useful once we also add support for .gz file format.

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 below are a few things what to do before sending a bug report.
In case of a crash (usually segmentation violation):
1. Try to create a small example how to reprocude the issue.
2. If you are writing an application using liblzma or libzfile,
double check that you are using the libraries correctly (for
example, that you didn't forget to call lzma_init()). If it is
the command line tool included in LZMA Utils that is crashing,
ignore this step.
3. Compile LZMA Utils with debugging code using configure switch
`--enable-debug'. If you are using GCC as the compiler, use
CFLAGS='-O0 -ggdb'. Don't strip the resulting binaries.
4. 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'.
5. 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 # Loads the app to the debugger.
(gdb) core core # Opens the coredump.
(gdb) bt # Prints the backtrace. Copy & paste to bug report.
(gdb) quit # Quits gdb.
Send your bug report to Lasse Collin <lasse.collin@tukaani.org>. Don't
send the core dump file or the actual executables. If you have a small
example file(s) (total size less than 100 KiB), please include it/them
as an attachment.
Do NOT complain about problems with LZMA Utils to Igor Pavlov.
Although the code of LZMA Utils is derived from his code, there are
a lot of changes, which may have introduced bugs not present in
the original version.

LZMA Utils FAQ
--------------
Copyright (C) 2007 Lasse Collin
Copying and distribution of this file, with or without modification,

notice and this notice are preserved.
Q: What are LZMA, LZMA Utils, lzma, .lzma, liblzma, LZMA SDK, LZMA_Alone,
7-Zip and p7zip?
A: LZMA stands for Lempel-Ziv-Markov chain-Algorithm. LZMA is the name
of the compression algorithm designed by Igor Pavlov. He is the author
of 7-Zip, which is a great LGPL'd compression tool for Microsoft
Windows operating systems. In addition to 7-Zip itself, also LZMA SDK
is available on the website of 7-Zip. LZMA SDK contains LZMA
implementations in C++, Java and C#. The C++ version is the original
implementation which is used also in 7-Zip itself.
Excluding the unrar plugin, 7-Zip is free software (free as in
freedom). Thanks to this, it was possible to port it to POSIX
platforms. The port was done and is maintained by myspace (TODO:
myspace's real name?). p7zip is a port of 7-Zip's command line version;
p7zip doesn't include the 7-Zip's GUI.
In POSIX world, users are used to gzip and bzip2 command line tools.
Developers know APIs of zlib and libbzip2. LZMA Utils try to ease
adoption of LZMA on free operating systems by providing a compression
library and a set of command line tools. The library is called liblzma.
It provides a zlib-like API making it easy to adapt LZMA compression in
existing applications. The main command line tool is known as lzma,
whose command line syntax is very similar to that of gzip and bzip2.
The original command line tool from LZMA SDK (lzma.exe) was found from
a directory called LZMA_Alone in the LZMA SDK. It used a simple header
format in .lzma files. This format was also used by LZMA Utils up to
and including 4.32.x. In LZMA Utils documentation, LZMA_Alone refers
to both the file format and the command line tool from LZMA SDK.
Because of various limitations of the LZMA_Alone file format, a new
file format was developed. Extending some existing format such as .gz
used by gzip was considered, but these formats were found to be too
limited. The filename suffix for the new .lzma format is `.lzma'. The
same suffix is also used for files in the LZMA_Alone format. To make
the transition to the new format as transparent as possible, LZMA Utils
support both the new and old formats transparently.
7-Zip and LZMA SDK: <http://7-zip.org/>
p7zip: <http://p7zip.sourceforge.net/>
LZMA Utils: <http://tukaani.org/lzma/>
Q: What LZMA implementations there are available?
A: LZMA SDK contains implementations in C++, Java and C#. The C++ version
is the original implementation which is part of 7-Zip. LZMA SDK
contains also a small LZMA decoder in C.
A port of LZMA SDK to Pascal was made by Alan Birtles
<http://www.birtles.org.uk/programming/>. It should work with
multiple Pascal programming language implementations.
LZMA Utils includes liblzma, which is directly based on LZMA SDK.
liblzma is written in C (C99, not C89). In contrast to C++ callback
API used by LZMA SDK, liblzma uses zlib-like stateful C API. I do not
want to comment whether both/former/latter/neither API(s) are good or
bad. The only reason to implement a zlib-like API was, that many
developers are already familiar with zlib, and very many applications
already use zlib. Having a similar API makes it easier to include LZMA
support in existing applications.
See also <http://en.wikipedia.org/wiki/LZMA#External_links>.
Q: Which file formats are supported by LZMA Utils?
A: Even when the raw LZMA stream is always the same, it can be wrapped
in different container formats. The preferred format is the new .lzma
format. It has magic bytes (the first six bytes: 0xFF 'L' 'Z' 'M'
'A' 0x00). The format supports chaining up to seven filters filters,
splitting data to multiple blocks for easier multi-threading and rough
random-access reading. The file integrity is verified using CRC32,
CRC64, or SHA256, and by verifying the uncompressed size of the file.
LZMA SDK includes a tool called LZMA_Alone. It supports uses a
primitive header which includes only the mandatory stream information
required by the LZMA decoder. This format can be both read and
written by liblzma and the command line tool (use --format=alone to
create such files).
.7z is the native archive format used by 7-Zip. This format is not
supported by liblzma, and probably will never be supported. You
should use e.g. p7zip to extract .7z files.
It is possible to implement custom file formats by using raw filter
mode in liblzma. In this mode the application needs to store the filter
properties and provide them to liblzma before starting to uncompress
the data.
Q: How can I identify files containing LZMA compressed data?
A: The preferred filename suffix for .lzma files is `.lzma'. `.tar.lzma'
may be abbreviated to `.tlz'. The same suffixes are used for files in
LZMA_Alone format. In practice this should be no problem since tools
included in LZMA Utils support both formats transparently.
Checking the magic bytes is easy way to detect files in the new .lzma
format (the first six bytes: 0xFF 'L' 'Z' 'M' 'A' 0x00). The "file"
command version FIXME contains magic strings for this format.
The old LZMA_Alone format has no magic bytes. Its header cannot contain
arbitrary bytes, thus it is possible to make a guess. Unfortunately the
guessing is usually too hard to be reliable, so don't try it unless you
are desperate.
Q: Does the lzma command line tool support sparse files?
A: Sparse files can (of course) be compressed like normal files, but
uncompression will not restore sparseness of the file. Use an archiver
tool to take care of sparseness before compressing the data with lzma.
The reason for this is that archiver tools handle files, while
compression tools handle streams or buffers. Being a sparse file is
a property of the file on the disk, not a property of the stream or
buffer.
Q: Can I recover parts of a broken LZMA file (e.g. corrupted CD-R)?
A: With LZMA_Alone and single-block .lzma files, you can uncompress the
file until you hit the first broken byte. The data after the broken
position is lost. LZMA relies on the uncompression history, and if
bytes are missing in the middle of the file, it is impossible to
reliably continue after the broken section.
With multi-block .lzma files it may be possible to locale the next
block in the file and continue decoding there. A limited recovery
tool for this kind of situations is planned.
Q: Is LZMA patented?
A: No, the authors are not aware of any patents that could affect LZMA.
However, due to nature of software patents, the authors cannot
guarantee, that LZMA isn't affected by any third party patent.
Q: Where can I find documentation about how LZMA works as an algorithm?
A: Read the source code, Luke. There is no documentation about LZMA
internals. It is possible that Igor Pavlov is the only person on
the Earth that completely knows and understands the algorithm.
You could begin by downloading LZMA SDK, and start reading from
the LZMA decoder to get some idea about the bitstream format.
Before you begin, you should know the basics of LZ77 and
range coding algorithms. LZMA is based on LZ77, but LZMA is
*a lot* more complex. Range coding is used to compress the
final bitstream like Huffman coding is used in Deflate.
Q: What are filters?
A: In context of .lzma files, a filter means an implementation of a
compression algorithm. The primary filter is LZMA, which is why
the names of the tools contain the letters LZMA.
liblzma and the new .lzma format support also other filters than LZMA.
There are different types of filters, which are suitable for different
types of data. Thus, to select the optimal filter and settings, the
type of the input data being compressed needs to be known.
Some filters are most useful when combined with another filter like
LZMA. These filters increase redundancy in the data, without changing
the size of the data, by taking advantage of properties specific to
the data being compressed.
So far, all the filters are always reversible. That is, no matter what
data you pass to a filter encoder, it can be always defiltered back to
the original form. Because of this, it is safe to compress for example
a software package that contains other file types than executables
using a filter specific to the architechture of the package being
compressed.
The old LZMA_Alone format supports only the LZMA filter.
Q: I cannot find BCJ and BCJ2 filters. Don't they exist in liblzma?
A: BCJ filter is called "x86" in liblzma. BCJ2 is not included,
because it requires using more than one encoded output stream.
Q: Can I use LZMA in proprietary, non-free applications?
A: liblzma is under the GNU LGPL version 2.1 or (at your opinion) any
later version. To summarise (*NOTE* This summary is not legally
binding, that is, it doesn't give you any extra permissions compared
to the LGPL. Read the GNU LGPL carefully for the exact license
conditions.):
* All the changes made into the library itself must be published
under the same license.
* End users must be able to replace the used liblzma. Easiest way
to assure this is to link dynamically against liblzma so users
can replace the shared library file if they want.
* You must make it clear to your users, that your application uses
liblzma, and that liblzma is free software under the GNU LGPL.
A copy of GNU LGPL must be included.
LZMA SDK contains a special exception which allows linking *unmodified*
code statically with a non-free application. This exception does *not*
apply to liblzma.
As an alternative, you can support the development of LZMA and 7-Zip
by buying a proprietary license from Igor Pavlov. See homepage of
LZMA SDK <http://7-zip.org/sdk.html> for more information. Note that
having a proprietary license from Igor Pavlov doesn't allow you to use
liblzma in a way that contradicts with the GNU LGPL, because liblzma
contains code that is not copyrighted by Igor Pavlov. Please contact
both Lasse Collin and Igor Pavlov if the license conditions of liblzma
are not suitable for you.
Q: I would like to help. What can I do?
A: See the TODO file. Please contact Lasse Collin before starting to do
anything, because it is possible that someone else is already working
on the same thing.
Q: How can I contact the authors?
A: Lasse Collin is the maintainer of LZMA Utils. You can contact him
either via IRC (Larhzu on #tukaani at Freenode or IRCnet). Email
should work too, <lasse.collin@tukaani.org>.
Igor Pavlov is the father of LZMA. He is the author of 7-Zip
and LZMA SDK. <http://7-zip.org/>
NOTE: Please don't bother Igor Pavlov with questions specific
to LZMA Utils.

LZMA Utils history
------------------
Tukaani distribution
In 2005, there was a small group working on Tukaani distribution, which
was a Slackware fork. One of the project goals was to fit the distro on
a single 700 MiB ISO-9660 image. Using LZMA instead of gzip helped a
lot. Roughly speaking, one could fit data that took 1000 MiB in gzipped
form into 700 MiB with LZMA. Naturally compression ratio varied across
packages, but this was what we got on average.
Slackware packages have traditionally had .tgz as the filename suffix,
which is an abbreviation of .tar.gz. A logical naming for LZMA
compressed packages was .tlz, being an abbreviation of .tar.lzma.
At the end of the year 2007, there's no distribution under the Tukaani
project anymore. Development of LZMA Utils still continues. Still,
there are .tlz packages around, because at least Vector Linux (a
Slackware based distribution) uses LZMA for its packages.
First versions of the modified pkgtools used the LZMA_Alone tool from
Igor Pavlov's LZMA SDK as is. It was fine, because users wouldn't need
to interact with LZMA_Alone directly. But people soon wanted to use
LZMA for other files too, and the interface of LZMA_Alone wasn't
comfortable for those used to gzip and bzip2.
First steps of LZMA Utils
The first version of LZMA Utils (4.22.0) included a shell script called
lzmash. It was wrapper that had gzip-like command line interface. It
used the LZMA_Alone tool from LZMA SDK to do all the real work. zgrep,
zdiff, and related scripts from gzip were adapted work with LZMA and
were part of the first LZMA Utils release too.
LZMA Utils 4.22.0 included also lzmadec, which was a small (less than
10 KiB) decoder-only command line tool. It was written on top of the
decoder-only C code found from the LZMA SDK. lzmadec was convenient in
situations where LZMA_Alone (a few hundred KiB) would be too big.
lzmash and lzmadec were written by Lasse Collin.
Second generation
The lzmash script was an ugly and not very secure hack. The last
version of LZMA Utils to use lzmash was 4.27.1.
LZMA Utils 4.32.0beta1 introduced a new lzma command line tool written
by Ville Koskinen. It was written in C++, and used the encoder and
decoder from C++ LZMA SDK with little modifications. This tool replaced
both the lzmash script and the LZMA_Alone command line tool in LZMA
Utils.
Introducing this new tool caused some temporary incompatibilities,
because LZMA_Alone executable was simply named lzma like the new
command line tool, but they had completely different command line
interface. The file format was still the same.
Lasse wrote liblzmadec, which was a small decoder-only library based on
the C code found from LZMA SDK. liblzmadec had API similar to zlib,
although there were some significant differences, which made it
non-trivial to use it in some applications designed for zlib and
libbzip2.
The lzmadec command line tool was converted to use liblzmadec.
Alexandre Sauvé helped converting build system to use GNU Autotools.
This made is easier to test for certain less portable features needed
by the new command line tool.
Since the new command line tool never got completely finished (for
example, it didn't support LZMA_OPT environment variable), the intent
was to not call 4.32.x stable. Similarly, liblzmadec wasn't polished,
but appeared to work well enough, so some people started using it too.
Because the development of the third generation of LZMA Utils was
delayed considerably (roughly two years), the 4.32.x branch had to be
kept maintained. It got some bug fixes now and then, and finally it was
decided to call it stable, although most of the missing features were
never added.
File format problems
The file format used by LZMA_Alone was primitive. It was designed for
embedded systems in mind, and thus provided only minimal set of
features. The two biggest problems for non-embedded use were lack of
magic bytes and integrity check.
Igor and Lasse started developing a new file format with some help from
Ville Koskinen, Mark Adler and Mikko Pouru. Designing the new format
took quite a long time. It was mostly because Lasse was quite slow at
getting things done due to personal reasons.
Near the end of the year 2007 the new format was practically finished.
Compared to LZMA_Alone format and the .gz format used by gzip, the new
.lzma format is quite complex as a whole. This means that tools having
*full* support for the new format would be larger and more complex than
the tools supporting only the old LZMA_Alone format.
For the situations where the full support for the .lzma format wouldn't
be required (embedded systems, operating system kernels), the new
format has a well-defined subset, which is easy to support with small
amount of code. It wouldn't be as small as an implementation using the
LZMA_Alone format, but the difference shouldn't be significant.
The new .lzma format allows dividing the data in multiple independent
blocks, which can be compressed and uncompressed independenly. This
makes multi-threading possible with algorithms that aren't inherently
parallel (such as LZMA). There's also a central index of the sizes of
the blocks, which makes it possible to do limited random-access reading
with granularity of the block size.
The new .lzma format uses the same filename suffix that was used for
LZMA_Alone files. The advantage is that users using the new tools won't
notice the change to the new format. The disadvantage is that the old
tools won't work with the new files.
Third generation
LZMA Utils 4.42.0alphas drop the rest of the C++ LZMA SDK. The LZMA and
other included filters (algorithm implementations) are still directly
based on LZMA SDK, but ported to C.
liblzma is now the core of LZMA Utils. It has zlib-like API, which
doesn't suffer from the problems of the API of liblzmadec. liblzma
supports not only LZMA, but several other filters, which together
can improve compression ratio even further with certain file types.
The lzma and lzmadec command line tools have been rewritten. They uses
liblzma to do the actual compressing or uncompressing.
The development of LZMA Utils 4.42.x is still in alpha stage. Several
features are still missing or don't fully work yet. Documentation is
also very minimal.

Advanced features of liblzma
----------------------------
0. Introduction
Most developers need only the basic features of liblzma. These
features allow single-threaded encoding and decoding of .lzma files
in streamed mode.
In some cases developers want more. The .lzma file format is
designed to allow multi-threaded encoding and decoding and limited
random-access reading. These features are possible in non-streamed
mode and limitedly also in streamed mode.
To take advange of these features, the application needs a custom
.lzma file format handler. liblzma provides a set of tools to ease
this task, but it's still quite a bit of work to get a good custom
.lzma handler done.
1. Where to begin
Start by reading the .lzma file format specification. Understanding
the basics of the .lzma file structure is required to implement a
custom .lzma file handler and to understand the rest of this document.
2. The basic components
2.1. Stream Header and tail
Stream Header begins the .lzma Stream and Stream tail ends it. Stream
Header is defined in the file format specification, but Stream tail
isn't (thus I write "tail" with a lower-case letter). Stream tail is
simply the Stream Flags and the Footer Magic Bytes fields together.
It was done this way in liblzma, because the Block coders take care
of the rest of the stuff in the Stream Footer.
For now, the size of Stream Header is fixed to 11 bytes. The header
<lzma/stream_flags.h> defines LZMA_STREAM_HEADER_SIZE, which you
should use instead of a hardcoded number. Similarly, Stream tail
is fixed to 3 bytes, and there is a constant LZMA_STREAM_TAIL_SIZE.
It is possible, that a future version of the .lzma format will have
variable-sized Stream Header and tail. As of writing, this seems so
unlikely though, that it was considered simplest to just use a
constant instead of providing a functions to get and store the sizes
of the Stream Header and tail.
2.x. Stream tail
For now, the size of Stream tail is fixed to 3 bytes. The header
<lzma/stream_flags.h> defines LZMA_STREAM_TAIL_SIZE, which you
should use instead of a hardcoded number.
3. Keeping track of size information
The lzma_info_* functions found from <lzma/info.h> should ease the
task of keeping track of sizes of the Blocks and also the Stream
as a whole. Using these functions is strongly recommended, because
there are surprisingly many situations where an error can occur,
and these functions check for possible errors every time some new
information becomes available.
If you find lzma_info_* functions lacking something that you would
find useful, please contact the author.
3.1. Start offset of the Stream
If you are storing the .lzma Stream inside anothe file format, or
for some other reason are placing the .lzma Stream to somewhere
else than to the beginning of the file, you should tell the starting
offset of the Stream using lzma_info_start_offset_set().
The start offset of the Stream is used for two distinct purporses.
First, knowing the start offset of the Stream allows
lzma_info_alignment_get() to correctly calculate the alignment of
every Block. This information is given to the Block encoder, which
will calculate the size of Header Padding so that Compressed Data
is alignment at an optimal offset.
Another use for start offset of the Stream is in random-access
reading. If you set the start offset of the Stream, lzma_info_locate()
will be able to calculate the offset relative to the beginning of the
file containing the Stream (instead of offset relative to the
beginning of the Stream).
3.2. Size of Stream Header
While the size of Stream Header is constant (11 bytes) in the current
version of the .lzma file format, this may change in future.
3.3. Size of Header Metadata Block
This information is needed when doing random-access reading, and
to verify the value of this field stored in Footer Metadata Block.
3.4. Total Size of the Data Blocks
3.5. Uncompressed Size of Data Blocks
3.6. Index
x. Alignment
There are a few slightly different types of alignment issues when
working with .lzma files.
The .lzma format doesn't strictly require any kind of alignment.
However, if the encoder carefully optimizes the alignment in all
situations, it can improve compression ratio, speed of the encoder
and decoder, and slightly help if the files get damaged and need
recovery.
Alignment has the most significant effect compression ratio FIXME
x.1. Compression ratio
Some filters take advantage of the alignment of the input data.
To get the best compression ratio, make sure that you feed these
filters correctly aligned data.
Some filters (e.g. LZMA) don't necessarily mind too much if the
input doesn't match the preferred alignment. With these filters
the penalty in compression ratio depends on the specific type of
data being compressed.
Other filters (e.g. PowerPC executable filter) won't work at all
with data that is improperly aligned. While the data can still
be de-filtered back to its original form, the benefit of the
filtering (better compression ratio) is completely lost, because
these filters expect certain patterns at properly aligned offsets.
The compression ratio may even worse with incorrectly aligned input
than without the filter.
x.1.1. Inter-filter alignment
When there are multiple filters chained, checking the alignment can
be useful not only with the input of the first filter and output of
the last filter, but also between the filters.
Inter-filter alignment important especially with the Subblock filter.
x.1.2. Further compression with external tools
This is relatively rare situation in practice, but still worth
understanding.
Let's say that there are several SPARC executables, which are each
filtered to separate .lzma files using only the SPARC filter. If
Uncompressed Size is written to the Block Header, the size of Block
Header may vary between the .lzma files. If no Padding is used in
the Block Header to correct the alignment, the starting offset of
the Compressed Data field will be differently aligned in different
.lzma files.
All these .lzma files are archived into a single .tar archive. Due
to nature of the .tar format, every file is aligned inside the
archive to an offset that is a multiple of 512 bytes.
The .tar archive is compressed into a new .lzma file using the LZMA
filter with options, that prefer input alignment of four bytes. Now
if the independent .lzma files don't have the same alignment of
the Compressed Data fields, the LZMA filter will be unable to take
advantage of the input alignment between the files in the .tar
archive, which reduces compression ratio.
Thus, even if you have only single Block per file, it can be good for
compression ratio to align the Compressed Data to optimal offset.
x.2. Speed
Most modern computers are faster when multi-byte data is located
at aligned offsets in RAM. Proper alignment of the Compressed Data
fields can slightly increase the speed of some filters.
x.3. Recovery
Aligning every Block Header to start at an offset with big enough
alignment may ease or at least speed up recovery of broken files.
y. Typical usage cases
y.x. Parsing the Stream backwards
You may need to parse the Stream backwards if you need to get
information such as the sizes of the Stream, Index, or Extra.
The basic procedure to do this follows.
Locate the end of the Stream. If the Stream is stored as is in a
standalone .lzma file, simply seek to the end of the file and start
reading backwards using appropriate buffer size. The file format
specification allows arbitrary amount of Footer Padding (zero or more
NUL bytes), which you skip before trying to decode the Stream tail.
Once you have located the end of the Stream (a non-NULL byte), make
sure you have at least the last LZMA_STREAM_TAIL_SIZE bytes of the
Stream in a buffer. If there isn't enough bytes left from the file,
the file is too small to contain a valid Stream. Decode the Stream
tail using lzma_stream_tail_decoder(). Store the offset of the first
byte of the Stream tail; you will need it later.
You may now want to do some internal verifications e.g. if the Check
type is supported by the liblzma build you are using.
Decode the Backward Size field with lzma_vli_reverse_decode(). The
field is at maximum of LZMA_VLI_BYTES_MAX bytes long. Check that
Backward Size is not zero. Store the offset of the first byte of
the Backward Size; you will need it later.
Now you know the Total Size of the last Block of the Stream. It's the
value of Backward Size plus the size of the Backward Size field. Note
that you cannot use lzma_vli_size() to calculate the size since there
might be padding; you need to use the real observed size of the
Backward Size field.
At this point, the operation continues differently for Single-Block
and Multi-Block Streams.
y.x.1. Single-Block Stream
There might be Uncompressed Size field present in the Stream Footer.
You cannot know it for sure unless you have already parsed the Block
Header earlier. For security reasons, you probably want to try to
decode the Uncompressed Size field, but you must not indicate any
error if decoding fails. Later you can give the decoded Uncompressed
Size to Block decoder if Uncopmressed Size isn't otherwise known;
this prevents it from producing too much output in case of (possibly
intentionally) corrupt file.
Calculate the the start offset of the Stream:
backward_offset - backward_size - LZMA_STREAM_HEADER_SIZE
backward_offset is the offset of the first byte of the Backward Size
field. Remember to check for integer overflows, which can occur with
invalid input files.
Seek to the beginning of the Stream. Decode the Stream Header using
lzma_stream_header_decoder(). Verify that the decoded Stream Flags
match the values found from Stream tail. You can use the
lzma_stream_flags_is_equal() macro for this.
Decode the Block Header. Verify that it isn't a Metadata Block, since
Single-Block Streams cannot have Metadata. If Uncompressed Size is
present in the Block Header, the value you tried to decode from the
Stream Footer must be ignored, since Uncompressed Size wasn't actually
present there. If Block Header doesn't have Uncompressed Size, and
decoding the Uncompressed Size field from the Stream Footer failed,
the file is corrupt.
If you were only looking for the Uncompressed Size of the Stream,
you now got that information, and you can stop processing the Stream.
To decode the Block, the same instructions apply as described in
FIXME. However, because you have some extra known information decoded
from the Stream Footer, you should give this information to the Block
decoder so that it can verify it while decoding:
- If Uncompressed Size is not present in the Block Header, set
lzma_options_block.uncompressed_size to the value you decoded
from the Stream Footer.
- Always set lzma_options_block.total_size to backward_size +
size_of_backward_size (you calculated this sum earlier already).
y.x.2. Multi-Block Stream
Calculate the start offset of the Footer Metadata Block:
backward_offset - backward_size
backward_offset is the offset of the first byte of the Backward Size
field. Remember to check for integer overflows, which can occur with
broken input files.
Decode the Block Header. Verify that it is a Metadata Block. Set
lzma_options_block.total_size to backward_size + size_of_backward_size
(you calculated this sum earlier already). Then decode the Footer
Metadata Block.
Store the decoded Footer Metadata to lzma_info structure using
lzma_info_set_metadata(). Set also the offset of the Backward Size
field using lzma_info_size_set(). Then you can get the start offset
of the Stream using lzma_info_size_get(). Note that any of these steps
may fail so don't omit error checking.
Seek to the beginning of the Stream. Decode the Stream Header using
lzma_stream_header_decoder(). Verify that the decoded Stream Flags
match the values found from Stream tail. You can use the
lzma_stream_flags_is_equal() macro for this.
If you were only looking for the Uncompressed Size of the Stream,
it's possible that you already have it now. If Uncompressed Size (or
whatever information you were looking for) isn't available yet,
continue by decoding also the Header Metadata Block. (If some
information is missing, the Header Metadata Block has to be present.)
Decoding the Data Blocks goes the same way as described in FIXME.
y.x.3. Variations
If you know the offset of the beginning of the Stream, you may want
to parse the Stream Header before parsing the Stream tail.

Hacking liblzma
---------------
0. Preface
This document gives some overall information about the internals of
liblzma, which should make it easier to start reading and modifying
the code.
1. Programming language
liblzma was written in C99. If you use GCC, this means that you need
at least GCC 3.x.x. GCC 2 isn't and won't be supported.
Some GCC-specific extensions are used *conditionally*. They aren't
required to build a full-featured library. Don't make the code rely
on any non-standard compiler extensions or even C99 features that
aren't portable between almost-C99 compatible compilers (for example
non-static inlines).
The public API headers are in C89. This is to avoid frustrating those
who maintain programs, which are strictly in C89 or C++.
An assumption about sizeof(size_t) is made. If this assumption is
wrong, some porting is probably needed:
sizeof(uint32_t) <= sizeof(size_t) <= sizeof(uint64_t)
2. Internal vs. external API

x. Designing new filters
All filters must be designed so that the decoder cannot consume
arbitrary amount input without producing any decoded output. Failing
to follow this rule makes liblzma vulnerable to DoS attacks if
untrusted files are decoded (usually they are untrusted).
An example should clarify the reason behind this requirement: There
are two filters in the chain. The decoder of the first filter produces
huge amount of output (many gigabytes or more) with a few bytes of
input, which gets passed to the decoder of the second filter. If the
data passed to the second filter is interpreted as something that
produces no output (e.g. padding), the filter chain as a whole
produces no output and consumes no input for a long period of time.
The above problem was present in the first versions of the Subblock
filter. A tiny .lzma file could have taken several years to decode
while it wouldn't produce any output at all. The problem was fixed
by adding limits for number of consecutive Padding bytes, and requiring
that some decoded output must be produced between Set Subfilter and
Unset Subfilter.
x. Implementing new filters
If the filter supports embedding End of Payload Marker, make sure that
when your filter detects End of Payload Marker,
- the usage of End of Payload Marker is actually allowed (i.e. End
of Input isn't used); and
- it also checks that there is no more input coming from the next
filter in the chain.
The second requirement is slightly tricky. It's possible that the next
filter hasn't returned LZMA_STREAM_END yet. It may even need a few
bytes more input before it will do so. You need to give it as much
input as it needs, and verify that it doesn't produce any output.
Don't call the next filter in the chain after it has returned
LZMA_STREAM_END (except in encoder if action == LZMA_SYNC_FLUSH).
It will result undefined behavior.
Be pedantic. If the input data isn't exactly valid, reject it.
At the moment, liblzma isn't modular. You will need to edit several
files in src/liblzma/common to include support for a new filter. grep
for LZMA_FILTER_LZMA to locate the files needing changes.

Introduction to liblzma
-----------------------
Writing applications to work with liblzma
liblzma API is split in several subheaders to improve readability and
maintainance. The subheaders must not be #included directly; simply
use `#include <lzma.h>' instead.
Those who have used zlib should find liblzma's API easy to use.
To developers who haven't used zlib before, I recommend learning
zlib first, because zlib has excellent documentation.
While the API is similar to that of zlib, there are some major
differences, which are summarized below.
For basic stream encoding, zlib has three functions (deflateInit(),
deflate(), and deflateEnd()). Similarly, there are three functions
for stream decoding (inflateInit(), inflate(), and inflateEnd()).
liblzma has only single coding and ending function. Thus, to
encode one may use, for example, lzma_stream_encoder_single(),
lzma_code(), and lzma_end(). Simlarly for decoding, one may
use lzma_auto_decoder(), lzma_code(), and lzma_end().
zlib has deflateReset() and inflateReset() to reset the stream
structure without reallocating all the memory. In liblzma, all
coder initialization functions are like zlib's reset functions:
the first-time initializations are done with the same functions
as the reinitializations (resetting).
To make all this work, liblzma needs to know when lzma_stream
doesn't already point to an allocated and initialized coder.
This is achieved by initializing lzma_stream structure with
LZMA_STREAM_INIT (static initialization) or LZMA_STREAM_INIT_VAR
(for exampple when new lzma_stream has been allocated with malloc()).
This initialization should be done exactly once per lzma_stream
structure to avoid leaking memory. Calling lzma_end() will leave
lzma_stream into a state comparable to the state achieved with
LZMA_STREAM_INIT and LZMA_STREAM_INIT_VAR.
Example probably clarifies a lot. With zlib, compression goes
roughly like this:
z_stream strm;
deflateInit(&strm, level);
deflate(&strm, Z_RUN);
deflate(&strm, Z_RUN);
...
deflate(&strm, Z_FINISH);
deflateEnd(&strm) or deflateReset(&strm)
With liblzma, it's slightly different:
lzma_stream strm = LZMA_STREAM_INIT;
lzma_stream_encoder_single(&strm, &options);
lzma_code(&strm, LZMA_RUN);
lzma_code(&strm, LZMA_RUN);
...
lzma_code(&strm, LZMA_FINISH);
lzma_end(&strm) or reinitialize for new coding work
Reinitialization in the last step can be any function that can
initialize lzma_stream; it doesn't need to be the same function
that was used for the previous initialization. If it is the same
function, liblzma will usually be able to re-use most of the
existing memory allocations (depends on how much the initialization
options change). If you reinitialize with different function,
liblzma will automatically free the memory of the previous coder.
File formats
liblzma supports multiple container formats for the compressed data.
Different initialization functions initialize the lzma_stream to
process different container formats. See the details from the public
header files.
The following functions are the most commonly used:
- lzma_stream_encoder_single(): Encodes Single-Block Stream; this
the recommended format for most purporses.
- lzma_alone_encoder(): Useful if you need to encode into the
legacy LZMA_Alone format.
- lzma_auto_decoder(): Decoder that automatically detects the
file format; recommended when you decode compressed files on
disk, because this way compatibility with the legacy LZMA_Alone
format is transparent.
- lzma_stream_decoder(): Decoder for Single- and Multi-Block
Streams; this is good if you want to accept only .lzma Streams.
Filters
liblzma supports multiple filters (algorithm implementations). The new
.lzma format supports filter-chain having up to seven filters. In the
filter chain, the output of one filter is input of the next filter in
the chain. The legacy LZMA_Alone format supports only one filter, and
that must always be LZMA.
General-purporse compression:
LZMA The main algorithm of liblzma (surprise!)
Branch/Call/Jump filters for executables:
x86 This filter is known as BCJ in 7-Zip
IA64 IA-64 (Itanium)
PowerPC Big endian PowerPC
ARM
ARM-Thumb
SPARC
Other filters:
Copy Dummy filter that simply copies all the data
from input to output.
Subblock Multi-purporse filter, that can
- embed End of Payload Marker if the previous
filter in the chain doesn't support it; and
- apply Subfilters, which filter only part
of the same compressed Block in the Stream.
Branch/Call/Jump filters never change the size of the data. They
should usually be used as a pre-filter for some compression filter
like LZMA.
Integrity checks
The .lzma Stream format uses CRC32 as the integrity check for
different file format headers. It is possible to omit CRC32 from
the Block Headers, but not from Stream Header. This is the reason
why CRC32 code cannot be disabled when building liblzma (in addition,
the LZMA encoder uses CRC32 for hashing, so that's another reason).
The integrity check of the actual data is calculated from the
uncompressed data. This check can be CRC32, CRC64, or SHA256.
It can also be omitted completely, although that usually is not
a good thing to do. There are free IDs left, so support for new
checks algorithms can be added later.
API and ABI stability
The API and ABI of liblzma isn't stable yet, although no huge
changes should happen. One potential place for change is the
lzma_options_subblock structure.
In the 4.42.0alpha phase, the shared library version number won't
be updated even if ABI breaks. I don't want to track the ABI changes
yet. Just rebuild everything when you upgrade liblzma until we get
to the beta stage.
Size of the library
While liblzma isn't huge, it is quite far from the smallest possible
LZMA implementation: full liblzma binary (with support for all
filters and other features) is way over 100 KiB, but the plain raw
LZMA decoder is only 5-10 KiB.
To decrease the size of the library, you can omit parts of the library
by passing certain options to the `configure' script. Disabling
everything but the decoders of the require filters will usually give
you a small enough library, but if you need a decoder for example
embedded in the operating system kernel, the code from liblzma probably
isn't suitable as is.
If you need a minimal implementation supporting .lzma Streams, you
may need to do partial rewrite. liblzma uses stateful API like zlib.
That increases the size of the library. Using callback API or even
simpler buffer-to-buffer API would allow smaller implementation.
LZMA SDK contains smaller LZMA decoder written in ANSI-C than
liblzma, so you may want to take a look at that code. However,
it doesn't (at least not yet) support the new .lzma Stream format.
Documentation
There's no other documentation than the public headers and this
text yet. Real docs will be written some day, I hope.

Using liblzma securely
----------------------
0. Introduction
This document discusses how to use liblzma securely. There are issues
that don't apply to zlib or libbzip2, so reading this document is
strongly recommended even for those who are very familiar with zlib
or libbzip2.
While making liblzma itself as secure as possible is essential, it's
out of scope of this document.
1. Memory usage
The memory usage of liblzma varies a lot.
1.1. Problem sources
1.1.1. Block coder
The memory requirements of Block encoder depend on the used filters
and their settings. The memory requirements of the Block decoder
depend on the which filters and with which filter settings the Block
was encoded. Usually the memory requirements of a decoder are equal
or less than the requirements of the encoder with the same settings.
While the typical memory requirements to decode a Block is from a few
hundred kilobytes to tens of megabytes, a maliciously constructed
files can require a lot more RAM to decode. With the current filters,
the maximum amount is about 7 GiB. If you use multi-threaded decoding,
every Block can require this amount of RAM, thus a four-threaded
decoder could suddenly try to allocate 28 GiB of RAM.
If you don't limit the maximum memory usage in any way, and there are
no resource limits set on the operating system side, one malicious
input file can run the system out of memory, or at least make it swap
badly for a long time. This is exceptionally bad on servers e.g.
email server doing virus scanning on incoming messages.
1.1.2. Metadata decoder
Multi-Block .lzma files contain at least one Metadata Block.
Externally the Metadata Blocks are similar to Data Blocks, so all
the issues mentioned about memory usage of Data Blocks applies to
Metadata Blocks too.
The uncompressed content of Metadata Blocks contain information about
the Stream as a whole, and optionally some Extra Records. The
information about the Stream is kept in liblzma's internal data
structures in RAM. Extra Records can contain arbitrary data. They are
not interpreted by liblzma, but liblzma will provide them to the
application in uninterpreted form if the application wishes so.
Usually the Uncompressed Size of a Metadata Block is small. Even on
extreme cases, it shouldn't be much bigger than a few megabytes. Once
the Metadata has been parsed into native data structures in liblzma,
it usually takes a little more memory than in the encoded form. For
all normal files, this is no problem, since the resulting memory usage
won't be too much.
The problem is that a maliciously constructed Metadata Block can
contain huge amount of "information", which liblzma will try to store
in its internal data structures. This may cause liblzma to allocate
all the available RAM unless some kind of resource usage limits are
applied.
Note that the Extra Records in Metadata are always parsed but, but
memory is allocated for them only if the application has requested
liblzma to provide the Extra Records to the application.
1.2. Solutions
If you need to decode files from untrusted sources (most people do),
you must limit the memory usage to avoid denial of service (DoS)
conditions caused by malicious input files.
The first step is to find out how much memory you are allowed consume
at maximum. This may be a hardcoded constant or derived from the
available RAM; whatever is appropriate in the application.
The simplest solution is to use setrlimit() if the kernel supports
RLIMIT_AS, which limits the memory usage of the whole process.
For more portable and fine-grained limitting, you can use
memory limitter functions found from <lzma/memlimit.h>.
1.2.1. Encoder
lzma_memory_usage() will give you a rough estimate about the memory
usage of the given filter chain. To dramatically simplify the internal
implementation, this function doesn't take into account all the small
helper data structures needed in various places; only the structures
with significant memory usage are taken into account. Still, the
accuracy of this function should be well within a mebibyte.
The Subblock filter is a special case. If a Subfilter has been
specified, it isn't taken into account when lzma_memory_usage()
calculates the memory usage. You need to calculate the memory usage
of the Subfilter separately.
Keeping track of Blocks in a Multi-Block Stream takes a few dozen
bytes of RAM per Block (size of the lzma_index structure plus overhead
of malloc()). It isn't a good idea to put tens of thousands of Blocks
into a Stream unless you have a very good reason to do so (compressed
dictionary could be an example of such situation).
Also keep the number and sizes of Extra Records sane. If you produce
the list of Extra Records automatically from some untrusted source,
you should not only validate the content of these Records, but also
their memory usage.
1.2.2. Decoder
A single-threaded decoder should simply use a memory limitter and
indicate an error if it runs out of memory.
Memory-limitting with multi-threaded decoding is tricky. The simple
solution is to divide the maximum allowed memory usage with the
maximum allowed threads, and give each Block decoder their own
independent lzma_memory_limitter. The drawback is that if one Block
needs notably more RAM than any other Block, the decoder will run out
of memory when in reality there would be plenty of free RAM.
An attractive alternative would be using shared lzma_memory_limitter.
Depending on the application and the expected type of input, this may
either be the best solution or a source of hard-to-repeat problems.
Consider the following requirements:
- You use at maximum of n threads.
- x(i) is the decoder memory requirements of the Block number i
in an expected input Stream.
- The memory limitter is set to higher value than the sum of n
highest values x(i).
(If you are better at explaining the above conditions, please
contribute your improved version.)
If the above conditions aren't met, it is possible that the decoding
will fail unpredictably. That is, on the same machine using the same
settings, the decoding may sometimes succeed and sometimes fail. This
is because sometimes threads may run so that the Blocks with highest
memory usage are tried to be decoded at the same time.
Most .lzma files have all the Blocks encoded with identical settings,
or at least the memory usage won't vary dramatically. That's why most
multi-threaded decoders probably want to use the simple "separate
lzma_memory_limitter for each thread" solution, possibly fallbacking
to single-threaded mode in case the per-thread memory limits aren't
enough in multi-threaded mode.
FIXME: Memory usage of Stream info.

2. Huge uncompressed output
2.1. Data Blocks
Decoding a tiny .lzma file can produce huge amount of uncompressed
output. There is an example file of 45 bytes, which decodes to 64 PiB
(that's 2^56 bytes). Uncompressing such a file to disk is likely to
fill even a bigger disk array. If the data is written to a pipe, it
may not fill the disk, but would still take very long time to finish.
To avoid denial of service conditions caused by huge amount of
uncompressed output, applications using liblzma should use some method
to limit the amount of output produced. The exact method depends on
the application.
All valid .lzma Streams make it possible to find out the uncompressed
size of the Stream without actually uncompressing the data. This
information is available in at least one of the Metadata Blocks.
Once the uncompressed size is parsed, the decoder can verify that
it doesn't exceed certain limits (e.g. available disk space).
When the uncompressed size is known, the decoder can actively keep
track of the amount of output produced so far, and that it doesn't
exceed the known uncompressed size. If it does exceed, the file is
known to be corrupt and an error should be indicated without
continuing to decode the rest of the file.
Unfortunately, finding the uncompressed size beforehand is often
possible only in non-streamed mode, because the needed information
could be in the Footer Metdata Block, which (obviously) is at the
end of the Stream. In purely streamed mode decoding, one may need to
use some rough arbitrary limits to prevent the problems described in
the beginning of this section.
2.2. Metadata
Metadata is stored in Metadata Blocks, which are very similar to
Data Blocks. Thus, the uncompressed size can be huge just like with
Data Blocks. The difference is, that the contents of Metadata Blocks
aren't given to the application as is, but parsed by liblzma. Still,
reading through a huge Metadata can take very long time, effectively
creating a denial of service like piping decoded a Data Block to
another process would do.
At first it would seem that using a memory limitter would prevent
this issue as a side effect. But it does so only if the application
requests liblzma to allocate the Extra Records and provide them to
the application. If Extra Records aren't requested, they aren't
allocated either. Still, the Extra Records are being read through
to validate that the Metadata is in proper format.
The solution is to limit the Uncompressed Size of a Metadata Block
to some relatively large value. This will make liblzma to give an
error when the given limit is reached.

Introduction to the lzma command line tool
------------------------------------------
Overview
The lzma command line tool is similar to gzip and bzip2, but for
compressing and uncompressing .lzma files.
Supported file formats
By default, the tool creates files in the new .lzma format. This can
be overriden with --format=FMT command line option. Use --format=alone
to create files in the old LZMA_Alone format.
By default, the tool uncompresses both the new .lzma format and
LZMA_Alone format. This is to make it transparent to switch from
the old LZMA_Alone format to the new .lzma format. Since both
formats use the same filename suffix, average user should never
notice which format was used.
Differences to gzip and bzip2
Standard input and output
Both gzip and bzip2 refuse to write compressed data to a terminal and
read compressed data from a terminal. With gzip (but not with bzip2),
this can be overriden with the `--force' option. lzma follows the
behavior of gzip here.
Usage of LZMA_OPT environment variable
gzip and bzip2 read GZIP and BZIP2 environment variables at startup.
These variables may contain extra command line options.
gzip and bzip2 allow passing not only options, but also end-of-options
indicator (`--') and filenames via the environment variable. No quoting
is supported with the filenames.
Here are examples with gzip. bzip2 behaves identically.
bash$ echo asdf > 'foo bar'
bash$ GZIP='"foo bar"' gzip
gzip: "foo: No such file or directory
gzip: bar": No such file or directory
bash$ GZIP=-- gzip --help
gzip: --help: No such file or directory
lzma silently ignores all non-option arguments given via the
environment variable LZMA_OPT. Like on the command line, everything
after `--' is taken as non-options, and thus ignored in LZMA_OPT.
bash$ LZMA_OPT='--help' lzma --version # Displays help
bash$ LZMA_OPT='-- --help' lzma --version # Displays version
Filter chain presets
Like in gzip and bzip2, lzma supports numbered presets from 1 to 9
where 1 is the fastest and 9 the best compression. 1 and 2 are for
fast compressing with small memory usage, 3 to 6 for good compression
ratio with medium memory usage, and 7 to 9 for excellent compression
ratio with higher memory requirements. The default is 7 if memory
usage limit allows.
In future, there will probably be an option like --preset=NAME, which
will contain more special presets for specific file types.
It's also possible that there will be some heuristics to select good
filters. For example, the tool could detect when a .tar archive is
being compressed, and enable x86 filter only for those files in the
.tar archive that are ELF or PE executables for x86.
Specifying custom filter chains
Custom filter chains are specified by using long options with the name
of the filters in correct order. For example, to pass the input data to
the x86 filter and the output of that to the LZMA filter, the following
command will do:
lzma --x86 --lzma filename
Some filters accept options, which are specified as a comma-separated
list of key=value pairs:
lzma --delta=distance=4 --lzma=dict=4Mi,lc=8,lp=2 filename
Memory usage control
By default, the command line tool limits memory usage to 1/3 of the
available physical RAM. If no preset or custom filter chain has been
given, the default preset will be used. If the memory limit is too
low for the default preset, the tool will silently switch to lower
preset.
When a preset or a custom filter chain has been specified and the
memory limit is too low, an error message is displayed and no files
are processed.
If the decoder hits the memory usage limit, an error is displayed and
no more files are processed.

/* Describe how to deal with options that follow non-option ARGV-elements.
If the caller did not specify anything,
the default is REQUIRE_ORDER if the environment variable
POSIXLY_CORRECT is defined, PERMUTE otherwise.
REQUIRE_ORDER means don't recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable POSIXLY_CORRECT, or using `+' as the first character
of the list of option characters, or by calling getopt.
PERMUTE is the default. We permute the contents of ARGV as we
scan, so that eventually all the non-options are at the end.
This allows options to be given in any order, even with programs
that were not written to expect this.
RETURN_IN_ORDER is an option available to programs that were
written to expect options and other ARGV-elements in any order
and that care about the ordering of the two. We describe each
non-option ARGV-element as if it were the argument of an option
with character code 1. Using `-' as the first character of the
list of option characters selects this mode of operation.
The special argument `--' forces an end of option-scanning regardless
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
`--' can cause `getopt' to return -1 with `optind' != ARGC. */

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

* is probably useless, because plain LZMA should provide better
* results.
*
* Due to above reasons, it was decided to keep the implementation
* of the RLE very simple. When the rle variable is non-zero, it
* subblock_data_size must be a multiple of rle. Once the Subblock
* encoder has got subblock_data_size bytes of input, it will check
* if the whole buffer of the last subblock_data_size can be
* represented with repeats of chunks having size of rle bytes.
*
* If there are consecutive identical buffers of subblock_data_size
* bytes, they will be encoded using a single repeat entry if
* possible.
*
* If need arises, more advanced RLE can be implemented later
* without breaking API or ABI.
