INSTRUCTIONS FOR BUILDING XPWN | |||
------------------------------ | |||
These are very basic instructions on how to build xpwn related projects, they | |||
are tailored to Debian based systems. They are not meant to be a substitute | |||
for experience in programming in GNU/Linux environments, but it should be a | |||
good starting point. | |||
1. Install a basic build environment (compilers, etc.): | |||
sudo apt-get install build-essential | |||
2. Install some prerequisites libraries required by xpwn: | |||
sudo apt-get install libcrypt-dev libz-dev libbz2-dev3 libusb-dev | |||
3. Install cmake. It is recommended you download and build it from the | |||
official cmake website, since versions >= 2.6.0 are recommended. | |||
wget http://www.cmake.org/files/v2.6/cmake-2.6.2.tar.gz | |||
tar zxvf cmake-2.6.2.tar.gz | |||
cd cmake-2.6.2 | |||
./configure | |||
make | |||
sudo make install | |||
Now you are ready to build xpwn. It is highly recommended that you build | |||
out-of-source (that is, the build products are not placed into the same | |||
folders as the sources). This is much neater and cleaning up is as simple as | |||
deleting the build products folder. | |||
Assuming xpwn sources are in ~/xpwn: | |||
4. Create a build folder | |||
cd ~ | |||
mkdir build | |||
cd build | |||
5. Create Makefiles | |||
cmake ~/xpwn | |||
6. Build | |||
make | |||
7. Package | |||
make package | |||
BUILDING USEFUL LIBRARIES | |||
------------------------- | |||
These command-lines can be substituted in for step 6. The products are in the | |||
subfolders (make package will not include them). | |||
xpwn library (for IPSW generation) | |||
make libXPwn.a | |||
Windows pwnmetheus library (for QuickPwn) | |||
make libpwnmetheus.dll | |||
HELPFUL MAKEFILE GENERATION COMMAND-LINES | |||
----------------------------------------- | |||
These command-lines can be substituted in for step 5. | |||
Add debugging symbols: | |||
cmake ~/xpwn -DCMAKE_C_FLAGS=-g | |||
Try to only use static libraries: | |||
cmake ~/xpwn -DBUILD_STATIC=YES | |||
CROSS-COMPILING | |||
--------------- | |||
This is a complex and advanced topic, but it is possible with the appropriate | |||
CMake toolchain files and properly configured build environment. I have | |||
crossbuilt Windows, OS X, Linux x86, Linux x64, and iPhone binaries from one | |||
Ubuntu machine. The source trees are properly configured for this task. | |||
MORE HELP | |||
--------- | |||
Consult the CMake documentation and wiki and look in the CMakeLists.txt files | |||
for hints on how things are supposed to work. |

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 | |||
