+ | ====== 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. | ||
+ | |||
+ | <code> | ||
+ | <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/]]. | ||
+ | </code> | ||
+ | |||
+ | 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: | ||
+ | |||
+ | <code> | ||
+ | <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. | ||
+ | </code> | ||
+ | |||
+ | 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]]. | ||
