Copyright (C) 2006 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. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other program whose authors commit to using it. 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 requirements that forbid anyone to deny you these rights or to ask you to surrender the rights. Therefore, you have certain responsibilities 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software. 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 associated erroneously with the original version. Some computers are designed to deny users access to install or run modified versions of the software inside them. This is fundamentally incompatible with the purpose of the GPL, which is to protect users' freedom to change the software. Therefore, the GPL ensures that the software it covers will not be restricted in this way. 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 places where they do, we wish to avoid the special danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. TERMS AND CONDITIONS 0. Definitions. In this License, each licensee is addressed as "you," while "the Program" refers to any work of authorship licensed under this License. A "modified" work includes, without limitation, versions in which material has been translated or added. A work "based on" another work means any modified version, formation of which requires permission under applicable copyright law. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means doing anything with it that requires permission under applicable copyright law, except executing it on a computer, or making modifications that you do not share. 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, excluding sublicensing. A party's "essential patent claims" in a work are all patent claims that the party can give permission to practice, whether already acquired or to be acquired, that would be infringed by making, using, or selling the work. 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 version of a work. The "System Libraries" of an executable work include every subunit such that (a) the identical subunit is normally included as an adjunct in the distribution of either a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the object code runs, or a compiler used to produce the object code, or an object code interpreter used to run it, and (b) the subunit (aside from possible incidental extensions) serves only to enable use of the work with that system component or compiler or interpreter, or to implement a widely used or standard interface for which an implementation is available to the public in source code form. 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, except its System Libraries, and except 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 scripts used to control those activities, interface definition files associated with the program source files, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by complex data communication or control flow between those subprograms and other parts of the work. The Corresponding Source also includes any encryption or authorization keys necessary to install and/or execute modified versions from source code in the recommended or principal context of use, such that they can implement all the same functionality in the same range of circumstances. (For instance, if the work is a DVD player and can play certain DVDs, it must be possible for modified versions to play those DVDs. If the work communicates with an online service, it must be possible for modified versions to communicate with the same online service in the same way such that the service cannot distinguish.) A key need not be included in cases where use of the work normally implies the user already has the key and can read and copy it, as in privacy applications where users generate their own keys. However, the fact that a key is generated based on the object code of the work or is present in hardware that limits its use does not alter the requirement to include it in the Corresponding Source. The Corresponding Source may include portions which do not formally state this License as their license, but qualify under section 7 for inclusion in a work under this License. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. 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 it 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. This License permits you to make and run privately modified versions of the Program, or have others make and run them on your behalf. However, this permission terminates, as to all such versions, if you bring suit against anyone for patent infringement of any of your essential patent claims in any such version, for making, using, selling or otherwise conveying a work based on the Program in compliance with this License. Propagation of covered works other than conveying is permitted without limitation. Sublicensing is not allowed; section 10 makes it unnecessary. Conveying is permitted under the conditions stated below. 3. No Denying Users' Rights through Technical Measures. Regardless of any other provision of this License, no permission is given for modes of conveying that deny users that run covered works the full exercise of the legal rights granted by this License. No covered work constitutes part of an effective technological "protection" measure under section 1201 of Title 17 of the United States Code. When you convey a covered work, you waive any legal power to forbid circumvention of technical measures that include use of the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing the legal rights of third parties against the work's users. 4.[1] Verbatim Copying. You may copy and 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 license notices and notices of the absence of any warranty; and give all recipients, along with the Program, a copy of this License and the central list (if any) required by section 7. The recipients of these copies will possess all the rights granted by this License (with any added terms under section 7). 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.[2] Conveying Modified Source Versions. You may copy and 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 above, provided that you also meet all of these conditions: a) The modified work must carry prominent notices stating that you changed the work and the date of any change. b) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License must apply, unmodified except as permitted by section 7 below, 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. c) If the modified work has interactive user interfaces, each must include a convenient feature that displays an appropriate copyright notice, and tells the user that there is no warranty for the program (or that you provide a warranty), that users may convey the modified work under this License, and how to view a copy of this License together with the central list (if any) of other terms in accord with section 7. Specifically, if the interface presents a list of user commands or options, such as a menu, a command to display this information must be prominent in the list; otherwise, the modified work must display this information at startup. However, if the Program has interactive interfaces that do not comply with this subsection, your modified work need not make them comply. To the extent that identifiable sections of the modified work, added by you, 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 convey them as separate works, not specifically for use in combination with the Program. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, 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.[3] Conveying Non-Source Forms. You may copy and 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 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 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 any third party 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. [b1) Convey the object code 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 provide 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 or 6b1. d) Convey the object code by offering access from a designated place, and offer equivalent access to the Corresponding Source in the same way through the same place at no extra 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 that supports equivalent copying facilities, provided you have explicitly arranged with the operator of that server to keep the Corresponding Source available for as long as needed to satisfy these requirements, and provided you maintain clear directions next to the object code saying where to find the Corresponding Source.] e) Convey the object code using peer-to-peer transmission provided you know that, and 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. The Corresponding Source conveyed in accord with this section must be in a format that is publicly documented, with an implementation available to the public in source code form, and must require no special password or key for unpacking, reading or copying. 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. 7. Additional Terms. You may have received the Program, or parts of it, under terms that supplement the terms of this License. These additional terms may include additional permissions, as provided in subsection 7a, and additional requirements, as provided in subsection 7b. When you convey copies of a covered work, unless the work also permits use under a previous version of this License, it must list, in one central place in the source code, the complete set of additional terms governing all or part of the work. a. Additional Permissions. Additional permissions make exceptions from one or more of the requirements of this License. A license document containing a clause that permits relicensing or conveying under this License shall be treated as a list of additional permissions, provided that the license document makes clear that no requirement in it survives such relicensing or conveying. Any additional permissions that are applicable to the entire Program are treated as though they were included in this License, as exceptions to its conditions, 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 terms. b. Additional Requirements. Additional requirements are terms that further constrain use, modification or propagation of covered works. This License affects only the procedure for enforcing additional requirements, and does not assert that they can be successfully enforced by the copyright holder. Only these kinds of additional requirements are allowed by this License: 0) terms that require preservation of specified reasonable legal notices or author attributions; or 1) terms that require that the origin of the material they cover not be misrepresented, or that modified versions of that material be marked in specific reasonable ways as different from the original version; or 2) warranty or liability disclaimers that differ from the disclaimers in this License; or 3) terms that prohibit or limit the use for publicity purposes of specified names of licensors or authors, or that require that certain specified trade names, trademarks, or service marks not be used for publicity purposes without express permission, other than in ways that are fair use under applicable trademark law; or 4) terms that require, if a modified version of the material they cover is a work intended to interact with users through a computer network, that those users be able to obtain copies of the Corresponding Source of the work through the same network session; or 5) terms that wholly or partially terminate, or allow termination of, permission for use of the material they cover, for a user who files a software patent lawsuit (that is, a lawsuit alleging that some software infringes a patent) not filed in retaliation or defense against the earlier filing of another software patent lawsuit, or in which the allegedly infringing software includes some of the covered material, possibly in combination with other software; or 6) terms that are precisely equivalent in type and extent to a requirement expressly stated in this License, or that deny permission for activities that are clearly not permitted, expressly or otherwise, by this License. All other additional requirements, including attorney's fees provisions, choice of law, forum, and venue clauses, arbitration clauses, mandatory contractual acceptance clauses, requirements regarding changes to the name of the work, and terms that require that conveyed copies be governed by a license other than this License, are prohibited. c. Terms Added or Removed by You. 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. Some additional permissions require their own removal in certain cases when you modify the work. Additional requirements are allowed only as stated in subsection 7b. If the Program as you received it purports to impose any other additional requirement, you may remove that requirement. You may place additional permissions, or additional requirements as allowed by subsection 7b, on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Adding requirements not allowed by subsection 7b is a violation of this License that may lead to termination of your rights under section 8. If you add terms to a covered work in accordance 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. 8.[4] Termination. You may not propagate or modify the Program except as expressly provided under this License. Any attempt otherwise to propagate or modify the Program is void. If you violate this License, any copyright holder may put you on notice by notifying you of the violation, by any reasonable means, provided 60 days have not elapsed since the last violation. Having put you on notice, the copyright holder may then terminate your license at any time. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as they remain in full compliance. 9.[5] 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 else grants you permission to propagate or modify the Program or any covered works. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating the Program (or any covered work), you indicate your acceptance of this License to do so, and all its terms and conditions. 10.[6] Automatic Licensing of Downstream Users. 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, including any additional terms introduced through section 7. You may not impose any further restrictions on the recipients' exercise of the rights thus granted or affirmed, except in the limited ways permitted by section 7. Therefore, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License. You are not responsible for enforcing compliance by third parties to this License. If propagation results from a transaction transferring control of an organization, each party to that transaction who receives a copy of the work also receives a license and a right to possession of the Corresponding Source of the work from the party's predecessor in interest. 11. Patents. You receive the Program with a covenant from each author and conveyor of the Program, and of any material, conveyed under this License, on which the Program is based, that the covenanting party will not assert (or cause others to assert) any of the party's essential patent claims in the material that the party conveyed, against you, arising from your exercise of rights under this License. If you convey a covered work, you similarly covenant to all recipients, including recipients of works based on the covered work, not to assert any of your essential patent claims in the covered work. If you convey a covered work, knowingly relying on a non- sublicensable patent license that is not generally available to all, you must either (1) act to shield downstream users against the possible patent infringement claims from which your license protects you, or (2) ensure that anyone can copy the Corresponding Source of the covered work, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means. 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.[7] 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 the Program, or other 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 accept a patent license that prohibits royalty-free conveying by 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 conveying the Program. [13.[8] Geographical Limitations. If the conveying 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 limitation on conveying, excluding those countries, so that conveying 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.] 14.[9] 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 this 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 this License, you may choose any version ever published by the Free Software Foundation. [15.[10] Requesting Exceptions. If you wish to incorporate parts of the Program into other free programs under other licenses, 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 16.[11] 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. 17.[12] 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 may modify and/or convey 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.
