nuclear@12: GNU GENERAL PUBLIC LICENSE nuclear@12: Version 3, 29 June 2007 nuclear@12: nuclear@12: Copyright (C) 2007 Free Software Foundation, Inc. nuclear@12: Everyone is permitted to copy and distribute verbatim copies nuclear@12: of this license document, but changing it is not allowed. nuclear@12: nuclear@12: Preamble nuclear@12: nuclear@12: The GNU General Public License is a free, copyleft license for nuclear@12: software and other kinds of works. nuclear@12: nuclear@12: The licenses for most software and other practical works are designed nuclear@12: to take away your freedom to share and change the works. By contrast, nuclear@12: the GNU General Public License is intended to guarantee your freedom to nuclear@12: share and change all versions of a program--to make sure it remains free nuclear@12: software for all its users. We, the Free Software Foundation, use the nuclear@12: GNU General Public License for most of our software; it applies also to nuclear@12: any other work released this way by its authors. You can apply it to nuclear@12: your programs, too. nuclear@12: nuclear@12: When we speak of free software, we are referring to freedom, not nuclear@12: price. Our General Public Licenses are designed to make sure that you nuclear@12: have the freedom to distribute copies of free software (and charge for nuclear@12: them if you wish), that you receive source code or can get it if you nuclear@12: want it, that you can change the software or use pieces of it in new nuclear@12: free programs, and that you know you can do these things. nuclear@12: nuclear@12: To protect your rights, we need to prevent others from denying you nuclear@12: these rights or asking you to surrender the rights. Therefore, you have nuclear@12: certain responsibilities if you distribute copies of the software, or if nuclear@12: you modify it: responsibilities to respect the freedom of others. nuclear@12: nuclear@12: For example, if you distribute copies of such a program, whether nuclear@12: gratis or for a fee, you must pass on to the recipients the same nuclear@12: freedoms that you received. You must make sure that they, too, receive nuclear@12: or can get the source code. And you must show them these terms so they nuclear@12: know their rights. nuclear@12: nuclear@12: Developers that use the GNU GPL protect your rights with two steps: nuclear@12: (1) assert copyright on the software, and (2) offer you this License nuclear@12: giving you legal permission to copy, distribute and/or modify it. nuclear@12: nuclear@12: For the developers' and authors' protection, the GPL clearly explains nuclear@12: that there is no warranty for this free software. For both users' and nuclear@12: authors' sake, the GPL requires that modified versions be marked as nuclear@12: changed, so that their problems will not be attributed erroneously to nuclear@12: authors of previous versions. nuclear@12: nuclear@12: Some devices are designed to deny users access to install or run nuclear@12: modified versions of the software inside them, although the manufacturer nuclear@12: can do so. This is fundamentally incompatible with the aim of nuclear@12: protecting users' freedom to change the software. The systematic nuclear@12: pattern of such abuse occurs in the area of products for individuals to nuclear@12: use, which is precisely where it is most unacceptable. Therefore, we nuclear@12: have designed this version of the GPL to prohibit the practice for those nuclear@12: products. If such problems arise substantially in other domains, we nuclear@12: stand ready to extend this provision to those domains in future versions nuclear@12: of the GPL, as needed to protect the freedom of users. nuclear@12: nuclear@12: Finally, every program is threatened constantly by software patents. nuclear@12: States should not allow patents to restrict development and use of nuclear@12: software on general-purpose computers, but in those that do, we wish to nuclear@12: avoid the special danger that patents applied to a free program could nuclear@12: make it effectively proprietary. To prevent this, the GPL assures that nuclear@12: patents cannot be used to render the program non-free. nuclear@12: nuclear@12: The precise terms and conditions for copying, distribution and nuclear@12: modification follow. nuclear@12: nuclear@12: TERMS AND CONDITIONS nuclear@12: nuclear@12: 0. Definitions. nuclear@12: nuclear@12: "This License" refers to version 3 of the GNU General Public License. nuclear@12: nuclear@12: "Copyright" also means copyright-like laws that apply to other kinds of nuclear@12: works, such as semiconductor masks. nuclear@12: nuclear@12: "The Program" refers to any copyrightable work licensed under this nuclear@12: License. Each licensee is addressed as "you". "Licensees" and nuclear@12: "recipients" may be individuals or organizations. nuclear@12: nuclear@12: To "modify" a work means to copy from or adapt all or part of the work nuclear@12: in a fashion requiring copyright permission, other than the making of an nuclear@12: exact copy. The resulting work is called a "modified version" of the nuclear@12: earlier work or a work "based on" the earlier work. nuclear@12: nuclear@12: A "covered work" means either the unmodified Program or a work based nuclear@12: on the Program. nuclear@12: nuclear@12: To "propagate" a work means to do anything with it that, without nuclear@12: permission, would make you directly or secondarily liable for nuclear@12: infringement under applicable copyright law, except executing it on a nuclear@12: computer or modifying a private copy. Propagation includes copying, nuclear@12: distribution (with or without modification), making available to the nuclear@12: public, and in some countries other activities as well. nuclear@12: nuclear@12: To "convey" a work means any kind of propagation that enables other nuclear@12: parties to make or receive copies. Mere interaction with a user through nuclear@12: a computer network, with no transfer of a copy, is not conveying. nuclear@12: nuclear@12: An interactive user interface displays "Appropriate Legal Notices" nuclear@12: to the extent that it includes a convenient and prominently visible nuclear@12: feature that (1) displays an appropriate copyright notice, and (2) nuclear@12: tells the user that there is no warranty for the work (except to the nuclear@12: extent that warranties are provided), that licensees may convey the nuclear@12: work under this License, and how to view a copy of this License. If nuclear@12: the interface presents a list of user commands or options, such as a nuclear@12: menu, a prominent item in the list meets this criterion. nuclear@12: nuclear@12: 1. Source Code. nuclear@12: nuclear@12: The "source code" for a work means the preferred form of the work nuclear@12: for making modifications to it. "Object code" means any non-source nuclear@12: form of a work. nuclear@12: nuclear@12: A "Standard Interface" means an interface that either is an official nuclear@12: standard defined by a recognized standards body, or, in the case of nuclear@12: interfaces specified for a particular programming language, one that nuclear@12: is widely used among developers working in that language. nuclear@12: nuclear@12: The "System Libraries" of an executable work include anything, other nuclear@12: than the work as a whole, that (a) is included in the normal form of nuclear@12: packaging a Major Component, but which is not part of that Major nuclear@12: Component, and (b) serves only to enable use of the work with that nuclear@12: Major Component, or to implement a Standard Interface for which an nuclear@12: implementation is available to the public in source code form. A nuclear@12: "Major Component", in this context, means a major essential component nuclear@12: (kernel, window system, and so on) of the specific operating system nuclear@12: (if any) on which the executable work runs, or a compiler used to nuclear@12: produce the work, or an object code interpreter used to run it. nuclear@12: nuclear@12: The "Corresponding Source" for a work in object code form means all nuclear@12: the source code needed to generate, install, and (for an executable nuclear@12: work) run the object code and to modify the work, including scripts to nuclear@12: control those activities. However, it does not include the work's nuclear@12: System Libraries, or general-purpose tools or generally available free nuclear@12: programs which are used unmodified in performing those activities but nuclear@12: which are not part of the work. For example, Corresponding Source nuclear@12: includes interface definition files associated with source files for nuclear@12: the work, and the source code for shared libraries and dynamically nuclear@12: linked subprograms that the work is specifically designed to require, nuclear@12: such as by intimate data communication or control flow between those nuclear@12: subprograms and other parts of the work. nuclear@12: nuclear@12: The Corresponding Source need not include anything that users nuclear@12: can regenerate automatically from other parts of the Corresponding nuclear@12: Source. nuclear@12: nuclear@12: The Corresponding Source for a work in source code form is that nuclear@12: same work. nuclear@12: nuclear@12: 2. Basic Permissions. nuclear@12: nuclear@12: All rights granted under this License are granted for the term of nuclear@12: copyright on the Program, and are irrevocable provided the stated nuclear@12: conditions are met. This License explicitly affirms your unlimited nuclear@12: permission to run the unmodified Program. The output from running a nuclear@12: covered work is covered by this License only if the output, given its nuclear@12: content, constitutes a covered work. This License acknowledges your nuclear@12: rights of fair use or other equivalent, as provided by copyright law. nuclear@12: nuclear@12: You may make, run and propagate covered works that you do not nuclear@12: convey, without conditions so long as your license otherwise remains nuclear@12: in force. You may convey covered works to others for the sole purpose nuclear@12: of having them make modifications exclusively for you, or provide you nuclear@12: with facilities for running those works, provided that you comply with nuclear@12: the terms of this License in conveying all material for which you do nuclear@12: not control copyright. Those thus making or running the covered works nuclear@12: for you must do so exclusively on your behalf, under your direction nuclear@12: and control, on terms that prohibit them from making any copies of nuclear@12: your copyrighted material outside their relationship with you. nuclear@12: nuclear@12: Conveying under any other circumstances is permitted solely under nuclear@12: the conditions stated below. Sublicensing is not allowed; section 10 nuclear@12: makes it unnecessary. nuclear@12: nuclear@12: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. nuclear@12: nuclear@12: No covered work shall be deemed part of an effective technological nuclear@12: measure under any applicable law fulfilling obligations under article nuclear@12: 11 of the WIPO copyright treaty adopted on 20 December 1996, or nuclear@12: similar laws prohibiting or restricting circumvention of such nuclear@12: measures. nuclear@12: nuclear@12: When you convey a covered work, you waive any legal power to forbid nuclear@12: circumvention of technological measures to the extent such circumvention nuclear@12: is effected by exercising rights under this License with respect to nuclear@12: the covered work, and you disclaim any intention to limit operation or nuclear@12: modification of the work as a means of enforcing, against the work's nuclear@12: users, your or third parties' legal rights to forbid circumvention of nuclear@12: technological measures. nuclear@12: nuclear@12: 4. Conveying Verbatim Copies. nuclear@12: nuclear@12: You may convey verbatim copies of the Program's source code as you nuclear@12: receive it, in any medium, provided that you conspicuously and nuclear@12: appropriately publish on each copy an appropriate copyright notice; nuclear@12: keep intact all notices stating that this License and any nuclear@12: non-permissive terms added in accord with section 7 apply to the code; nuclear@12: keep intact all notices of the absence of any warranty; and give all nuclear@12: recipients a copy of this License along with the Program. nuclear@12: nuclear@12: You may charge any price or no price for each copy that you convey, nuclear@12: and you may offer support or warranty protection for a fee. nuclear@12: nuclear@12: 5. Conveying Modified Source Versions. nuclear@12: nuclear@12: You may convey a work based on the Program, or the modifications to nuclear@12: produce it from the Program, in the form of source code under the nuclear@12: terms of section 4, provided that you also meet all of these conditions: nuclear@12: nuclear@12: a) The work must carry prominent notices stating that you modified nuclear@12: it, and giving a relevant date. nuclear@12: nuclear@12: b) The work must carry prominent notices stating that it is nuclear@12: released under this License and any conditions added under section nuclear@12: 7. This requirement modifies the requirement in section 4 to nuclear@12: "keep intact all notices". nuclear@12: nuclear@12: c) You must license the entire work, as a whole, under this nuclear@12: License to anyone who comes into possession of a copy. This nuclear@12: License will therefore apply, along with any applicable section 7 nuclear@12: additional terms, to the whole of the work, and all its parts, nuclear@12: regardless of how they are packaged. This License gives no nuclear@12: permission to license the work in any other way, but it does not nuclear@12: invalidate such permission if you have separately received it. nuclear@12: nuclear@12: d) If the work has interactive user interfaces, each must display nuclear@12: Appropriate Legal Notices; however, if the Program has interactive nuclear@12: interfaces that do not display Appropriate Legal Notices, your nuclear@12: work need not make them do so. nuclear@12: nuclear@12: A compilation of a covered work with other separate and independent nuclear@12: works, which are not by their nature extensions of the covered work, nuclear@12: and which are not combined with it such as to form a larger program, nuclear@12: in or on a volume of a storage or distribution medium, is called an nuclear@12: "aggregate" if the compilation and its resulting copyright are not nuclear@12: used to limit the access or legal rights of the compilation's users nuclear@12: beyond what the individual works permit. Inclusion of a covered work nuclear@12: in an aggregate does not cause this License to apply to the other nuclear@12: parts of the aggregate. nuclear@12: nuclear@12: 6. Conveying Non-Source Forms. nuclear@12: nuclear@12: You may convey a covered work in object code form under the terms nuclear@12: of sections 4 and 5, provided that you also convey the nuclear@12: machine-readable Corresponding Source under the terms of this License, nuclear@12: in one of these ways: nuclear@12: nuclear@12: a) Convey the object code in, or embodied in, a physical product nuclear@12: (including a physical distribution medium), accompanied by the nuclear@12: Corresponding Source fixed on a durable physical medium nuclear@12: customarily used for software interchange. nuclear@12: nuclear@12: b) Convey the object code in, or embodied in, a physical product nuclear@12: (including a physical distribution medium), accompanied by a nuclear@12: written offer, valid for at least three years and valid for as nuclear@12: long as you offer spare parts or customer support for that product nuclear@12: model, to give anyone who possesses the object code either (1) a nuclear@12: copy of the Corresponding Source for all the software in the nuclear@12: product that is covered by this License, on a durable physical nuclear@12: medium customarily used for software interchange, for a price no nuclear@12: more than your reasonable cost of physically performing this nuclear@12: conveying of source, or (2) access to copy the nuclear@12: Corresponding Source from a network server at no charge. nuclear@12: nuclear@12: c) Convey individual copies of the object code with a copy of the nuclear@12: written offer to provide the Corresponding Source. This nuclear@12: alternative is allowed only occasionally and noncommercially, and nuclear@12: only if you received the object code with such an offer, in accord nuclear@12: with subsection 6b. nuclear@12: nuclear@12: d) Convey the object code by offering access from a designated nuclear@12: place (gratis or for a charge), and offer equivalent access to the nuclear@12: Corresponding Source in the same way through the same place at no nuclear@12: further charge. You need not require recipients to copy the nuclear@12: Corresponding Source along with the object code. If the place to nuclear@12: copy the object code is a network server, the Corresponding Source nuclear@12: may be on a different server (operated by you or a third party) nuclear@12: that supports equivalent copying facilities, provided you maintain nuclear@12: clear directions next to the object code saying where to find the nuclear@12: Corresponding Source. Regardless of what server hosts the nuclear@12: Corresponding Source, you remain obligated to ensure that it is nuclear@12: available for as long as needed to satisfy these requirements. nuclear@12: nuclear@12: e) Convey the object code using peer-to-peer transmission, provided nuclear@12: you inform other peers where the object code and Corresponding nuclear@12: Source of the work are being offered to the general public at no nuclear@12: charge under subsection 6d. nuclear@12: nuclear@12: A separable portion of the object code, whose source code is excluded nuclear@12: from the Corresponding Source as a System Library, need not be nuclear@12: included in conveying the object code work. nuclear@12: nuclear@12: A "User Product" is either (1) a "consumer product", which means any nuclear@12: tangible personal property which is normally used for personal, family, nuclear@12: or household purposes, or (2) anything designed or sold for incorporation nuclear@12: into a dwelling. In determining whether a product is a consumer product, nuclear@12: doubtful cases shall be resolved in favor of coverage. For a particular nuclear@12: product received by a particular user, "normally used" refers to a nuclear@12: typical or common use of that class of product, regardless of the status nuclear@12: of the particular user or of the way in which the particular user nuclear@12: actually uses, or expects or is expected to use, the product. A product nuclear@12: is a consumer product regardless of whether the product has substantial nuclear@12: commercial, industrial or non-consumer uses, unless such uses represent nuclear@12: the only significant mode of use of the product. nuclear@12: nuclear@12: "Installation Information" for a User Product means any methods, nuclear@12: procedures, authorization keys, or other information required to install nuclear@12: and execute modified versions of a covered work in that User Product from nuclear@12: a modified version of its Corresponding Source. The information must nuclear@12: suffice to ensure that the continued functioning of the modified object nuclear@12: code is in no case prevented or interfered with solely because nuclear@12: modification has been made. nuclear@12: nuclear@12: If you convey an object code work under this section in, or with, or nuclear@12: specifically for use in, a User Product, and the conveying occurs as nuclear@12: part of a transaction in which the right of possession and use of the nuclear@12: User Product is transferred to the recipient in perpetuity or for a nuclear@12: fixed term (regardless of how the transaction is characterized), the nuclear@12: Corresponding Source conveyed under this section must be accompanied nuclear@12: by the Installation Information. But this requirement does not apply nuclear@12: if neither you nor any third party retains the ability to install nuclear@12: modified object code on the User Product (for example, the work has nuclear@12: been installed in ROM). nuclear@12: nuclear@12: The requirement to provide Installation Information does not include a nuclear@12: requirement to continue to provide support service, warranty, or updates nuclear@12: for a work that has been modified or installed by the recipient, or for nuclear@12: the User Product in which it has been modified or installed. Access to a nuclear@12: network may be denied when the modification itself materially and nuclear@12: adversely affects the operation of the network or violates the rules and nuclear@12: protocols for communication across the network. nuclear@12: nuclear@12: Corresponding Source conveyed, and Installation Information provided, nuclear@12: in accord with this section must be in a format that is publicly nuclear@12: documented (and with an implementation available to the public in nuclear@12: source code form), and must require no special password or key for nuclear@12: unpacking, reading or copying. nuclear@12: nuclear@12: 7. Additional Terms. nuclear@12: nuclear@12: "Additional permissions" are terms that supplement the terms of this nuclear@12: License by making exceptions from one or more of its conditions. nuclear@12: Additional permissions that are applicable to the entire Program shall nuclear@12: be treated as though they were included in this License, to the extent nuclear@12: that they are valid under applicable law. If additional permissions nuclear@12: apply only to part of the Program, that part may be used separately nuclear@12: under those permissions, but the entire Program remains governed by nuclear@12: this License without regard to the additional permissions. nuclear@12: nuclear@12: When you convey a copy of a covered work, you may at your option nuclear@12: remove any additional permissions from that copy, or from any part of nuclear@12: it. (Additional permissions may be written to require their own nuclear@12: removal in certain cases when you modify the work.) You may place nuclear@12: additional permissions on material, added by you to a covered work, nuclear@12: for which you have or can give appropriate copyright permission. nuclear@12: nuclear@12: Notwithstanding any other provision of this License, for material you nuclear@12: add to a covered work, you may (if authorized by the copyright holders of nuclear@12: that material) supplement the terms of this License with terms: nuclear@12: nuclear@12: a) Disclaiming warranty or limiting liability differently from the nuclear@12: terms of sections 15 and 16 of this License; or nuclear@12: nuclear@12: b) Requiring preservation of specified reasonable legal notices or nuclear@12: author attributions in that material or in the Appropriate Legal nuclear@12: Notices displayed by works containing it; or nuclear@12: nuclear@12: c) Prohibiting misrepresentation of the origin of that material, or nuclear@12: requiring that modified versions of such material be marked in nuclear@12: reasonable ways as different from the original version; or nuclear@12: nuclear@12: d) Limiting the use for publicity purposes of names of licensors or nuclear@12: authors of the material; or nuclear@12: nuclear@12: e) Declining to grant rights under trademark law for use of some nuclear@12: trade names, trademarks, or service marks; or nuclear@12: nuclear@12: f) Requiring indemnification of licensors and authors of that nuclear@12: material by anyone who conveys the material (or modified versions of nuclear@12: it) with contractual assumptions of liability to the recipient, for nuclear@12: any liability that these contractual assumptions directly impose on nuclear@12: those licensors and authors. nuclear@12: nuclear@12: All other non-permissive additional terms are considered "further nuclear@12: restrictions" within the meaning of section 10. If the Program as you nuclear@12: received it, or any part of it, contains a notice stating that it is nuclear@12: governed by this License along with a term that is a further nuclear@12: restriction, you may remove that term. If a license document contains nuclear@12: a further restriction but permits relicensing or conveying under this nuclear@12: License, you may add to a covered work material governed by the terms nuclear@12: of that license document, provided that the further restriction does nuclear@12: not survive such relicensing or conveying. nuclear@12: nuclear@12: If you add terms to a covered work in accord with this section, you nuclear@12: must place, in the relevant source files, a statement of the nuclear@12: additional terms that apply to those files, or a notice indicating nuclear@12: where to find the applicable terms. nuclear@12: nuclear@12: Additional terms, permissive or non-permissive, may be stated in the nuclear@12: form of a separately written license, or stated as exceptions; nuclear@12: the above requirements apply either way. nuclear@12: nuclear@12: 8. Termination. nuclear@12: nuclear@12: You may not propagate or modify a covered work except as expressly nuclear@12: provided under this License. Any attempt otherwise to propagate or nuclear@12: modify it is void, and will automatically terminate your rights under nuclear@12: this License (including any patent licenses granted under the third nuclear@12: paragraph of section 11). nuclear@12: nuclear@12: However, if you cease all violation of this License, then your nuclear@12: license from a particular copyright holder is reinstated (a) nuclear@12: provisionally, unless and until the copyright holder explicitly and nuclear@12: finally terminates your license, and (b) permanently, if the copyright nuclear@12: holder fails to notify you of the violation by some reasonable means nuclear@12: prior to 60 days after the cessation. nuclear@12: nuclear@12: Moreover, your license from a particular copyright holder is nuclear@12: reinstated permanently if the copyright holder notifies you of the nuclear@12: violation by some reasonable means, this is the first time you have nuclear@12: received notice of violation of this License (for any work) from that nuclear@12: copyright holder, and you cure the violation prior to 30 days after nuclear@12: your receipt of the notice. nuclear@12: nuclear@12: Termination of your rights under this section does not terminate the nuclear@12: licenses of parties who have received copies or rights from you under nuclear@12: this License. If your rights have been terminated and not permanently nuclear@12: reinstated, you do not qualify to receive new licenses for the same nuclear@12: material under section 10. nuclear@12: nuclear@12: 9. Acceptance Not Required for Having Copies. nuclear@12: nuclear@12: You are not required to accept this License in order to receive or nuclear@12: run a copy of the Program. Ancillary propagation of a covered work nuclear@12: occurring solely as a consequence of using peer-to-peer transmission nuclear@12: to receive a copy likewise does not require acceptance. However, nuclear@12: nothing other than this License grants you permission to propagate or nuclear@12: modify any covered work. These actions infringe copyright if you do nuclear@12: not accept this License. Therefore, by modifying or propagating a nuclear@12: covered work, you indicate your acceptance of this License to do so. nuclear@12: nuclear@12: 10. Automatic Licensing of Downstream Recipients. nuclear@12: nuclear@12: Each time you convey a covered work, the recipient automatically nuclear@12: receives a license from the original licensors, to run, modify and nuclear@12: propagate that work, subject to this License. You are not responsible nuclear@12: for enforcing compliance by third parties with this License. nuclear@12: nuclear@12: An "entity transaction" is a transaction transferring control of an nuclear@12: organization, or substantially all assets of one, or subdividing an nuclear@12: organization, or merging organizations. If propagation of a covered nuclear@12: work results from an entity transaction, each party to that nuclear@12: transaction who receives a copy of the work also receives whatever nuclear@12: licenses to the work the party's predecessor in interest had or could nuclear@12: give under the previous paragraph, plus a right to possession of the nuclear@12: Corresponding Source of the work from the predecessor in interest, if nuclear@12: the predecessor has it or can get it with reasonable efforts. nuclear@12: nuclear@12: You may not impose any further restrictions on the exercise of the nuclear@12: rights granted or affirmed under this License. For example, you may nuclear@12: not impose a license fee, royalty, or other charge for exercise of nuclear@12: rights granted under this License, and you may not initiate litigation nuclear@12: (including a cross-claim or counterclaim in a lawsuit) alleging that nuclear@12: any patent claim is infringed by making, using, selling, offering for nuclear@12: sale, or importing the Program or any portion of it. nuclear@12: nuclear@12: 11. Patents. nuclear@12: nuclear@12: A "contributor" is a copyright holder who authorizes use under this nuclear@12: License of the Program or a work on which the Program is based. The nuclear@12: work thus licensed is called the contributor's "contributor version". nuclear@12: nuclear@12: A contributor's "essential patent claims" are all patent claims nuclear@12: owned or controlled by the contributor, whether already acquired or nuclear@12: hereafter acquired, that would be infringed by some manner, permitted nuclear@12: by this License, of making, using, or selling its contributor version, nuclear@12: but do not include claims that would be infringed only as a nuclear@12: consequence of further modification of the contributor version. For nuclear@12: purposes of this definition, "control" includes the right to grant nuclear@12: patent sublicenses in a manner consistent with the requirements of nuclear@12: this License. nuclear@12: nuclear@12: Each contributor grants you a non-exclusive, worldwide, royalty-free nuclear@12: patent license under the contributor's essential patent claims, to nuclear@12: make, use, sell, offer for sale, import and otherwise run, modify and nuclear@12: propagate the contents of its contributor version. nuclear@12: nuclear@12: In the following three paragraphs, a "patent license" is any express nuclear@12: agreement or commitment, however denominated, not to enforce a patent nuclear@12: (such as an express permission to practice a patent or covenant not to nuclear@12: sue for patent infringement). To "grant" such a patent license to a nuclear@12: party means to make such an agreement or commitment not to enforce a nuclear@12: patent against the party. nuclear@12: nuclear@12: If you convey a covered work, knowingly relying on a patent license, nuclear@12: and the Corresponding Source of the work is not available for anyone nuclear@12: to copy, free of charge and under the terms of this License, through a nuclear@12: publicly available network server or other readily accessible means, nuclear@12: then you must either (1) cause the Corresponding Source to be so nuclear@12: available, or (2) arrange to deprive yourself of the benefit of the nuclear@12: patent license for this particular work, or (3) arrange, in a manner nuclear@12: consistent with the requirements of this License, to extend the patent nuclear@12: license to downstream recipients. "Knowingly relying" means you have nuclear@12: actual knowledge that, but for the patent license, your conveying the nuclear@12: covered work in a country, or your recipient's use of the covered work nuclear@12: in a country, would infringe one or more identifiable patents in that nuclear@12: country that you have reason to believe are valid. nuclear@12: nuclear@12: If, pursuant to or in connection with a single transaction or nuclear@12: arrangement, you convey, or propagate by procuring conveyance of, a nuclear@12: covered work, and grant a patent license to some of the parties nuclear@12: receiving the covered work authorizing them to use, propagate, modify nuclear@12: or convey a specific copy of the covered work, then the patent license nuclear@12: you grant is automatically extended to all recipients of the covered nuclear@12: work and works based on it. nuclear@12: nuclear@12: A patent license is "discriminatory" if it does not include within nuclear@12: the scope of its coverage, prohibits the exercise of, or is nuclear@12: conditioned on the non-exercise of one or more of the rights that are nuclear@12: specifically granted under this License. You may not convey a covered nuclear@12: work if you are a party to an arrangement with a third party that is nuclear@12: in the business of distributing software, under which you make payment nuclear@12: to the third party based on the extent of your activity of conveying nuclear@12: the work, and under which the third party grants, to any of the nuclear@12: parties who would receive the covered work from you, a discriminatory nuclear@12: patent license (a) in connection with copies of the covered work nuclear@12: conveyed by you (or copies made from those copies), or (b) primarily nuclear@12: for and in connection with specific products or compilations that nuclear@12: contain the covered work, unless you entered into that arrangement, nuclear@12: or that patent license was granted, prior to 28 March 2007. nuclear@12: nuclear@12: Nothing in this License shall be construed as excluding or limiting nuclear@12: any implied license or other defenses to infringement that may nuclear@12: otherwise be available to you under applicable patent law. nuclear@12: nuclear@12: 12. No Surrender of Others' Freedom. nuclear@12: nuclear@12: If conditions are imposed on you (whether by court order, agreement or nuclear@12: otherwise) that contradict the conditions of this License, they do not nuclear@12: excuse you from the conditions of this License. If you cannot convey a nuclear@12: covered work so as to satisfy simultaneously your obligations under this nuclear@12: License and any other pertinent obligations, then as a consequence you may nuclear@12: not convey it at all. For example, if you agree to terms that obligate you nuclear@12: to collect a royalty for further conveying from those to whom you convey nuclear@12: the Program, the only way you could satisfy both those terms and this nuclear@12: License would be to refrain entirely from conveying the Program. nuclear@12: nuclear@12: 13. Use with the GNU Affero General Public License. nuclear@12: nuclear@12: Notwithstanding any other provision of this License, you have nuclear@12: permission to link or combine any covered work with a work licensed nuclear@12: under version 3 of the GNU Affero General Public License into a single nuclear@12: combined work, and to convey the resulting work. The terms of this nuclear@12: License will continue to apply to the part which is the covered work, nuclear@12: but the special requirements of the GNU Affero General Public License, nuclear@12: section 13, concerning interaction through a network will apply to the nuclear@12: combination as such. nuclear@12: nuclear@12: 14. Revised Versions of this License. nuclear@12: nuclear@12: The Free Software Foundation may publish revised and/or new versions of nuclear@12: the GNU General Public License from time to time. Such new versions will nuclear@12: be similar in spirit to the present version, but may differ in detail to nuclear@12: address new problems or concerns. nuclear@12: nuclear@12: Each version is given a distinguishing version number. If the nuclear@12: Program specifies that a certain numbered version of the GNU General nuclear@12: Public License "or any later version" applies to it, you have the nuclear@12: option of following the terms and conditions either of that numbered nuclear@12: version or of any later version published by the Free Software nuclear@12: Foundation. If the Program does not specify a version number of the nuclear@12: GNU General Public License, you may choose any version ever published nuclear@12: by the Free Software Foundation. nuclear@12: nuclear@12: If the Program specifies that a proxy can decide which future nuclear@12: versions of the GNU General Public License can be used, that proxy's nuclear@12: public statement of acceptance of a version permanently authorizes you nuclear@12: to choose that version for the Program. nuclear@12: nuclear@12: Later license versions may give you additional or different nuclear@12: permissions. However, no additional obligations are imposed on any nuclear@12: author or copyright holder as a result of your choosing to follow a nuclear@12: later version. nuclear@12: nuclear@12: 15. Disclaimer of Warranty. nuclear@12: nuclear@12: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY nuclear@12: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT nuclear@12: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY nuclear@12: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, nuclear@12: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR nuclear@12: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM nuclear@12: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF nuclear@12: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. nuclear@12: nuclear@12: 16. Limitation of Liability. nuclear@12: nuclear@12: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING nuclear@12: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS nuclear@12: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY nuclear@12: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE nuclear@12: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF nuclear@12: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD nuclear@12: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), nuclear@12: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF nuclear@12: SUCH DAMAGES. nuclear@12: nuclear@12: 17. Interpretation of Sections 15 and 16. nuclear@12: nuclear@12: If the disclaimer of warranty and limitation of liability provided nuclear@12: above cannot be given local legal effect according to their terms, nuclear@12: reviewing courts shall apply local law that most closely approximates nuclear@12: an absolute waiver of all civil liability in connection with the nuclear@12: Program, unless a warranty or assumption of liability accompanies a nuclear@12: copy of the Program in return for a fee. nuclear@12: nuclear@12: END OF TERMS AND CONDITIONS nuclear@12: nuclear@12: How to Apply These Terms to Your New Programs nuclear@12: nuclear@12: If you develop a new program, and you want it to be of the greatest nuclear@12: possible use to the public, the best way to achieve this is to make it nuclear@12: free software which everyone can redistribute and change under these terms. nuclear@12: nuclear@12: To do so, attach the following notices to the program. It is safest nuclear@12: to attach them to the start of each source file to most effectively nuclear@12: state the exclusion of warranty; and each file should have at least nuclear@12: the "copyright" line and a pointer to where the full notice is found. nuclear@12: nuclear@12: nuclear@12: Copyright (C) nuclear@12: nuclear@12: This program is free software: you can redistribute it and/or modify nuclear@12: it under the terms of the GNU General Public License as published by nuclear@12: the Free Software Foundation, either version 3 of the License, or nuclear@12: (at your option) any later version. nuclear@12: nuclear@12: This program is distributed in the hope that it will be useful, nuclear@12: but WITHOUT ANY WARRANTY; without even the implied warranty of nuclear@12: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the nuclear@12: GNU General Public License for more details. nuclear@12: nuclear@12: You should have received a copy of the GNU General Public License nuclear@12: along with this program. If not, see . nuclear@12: nuclear@12: Also add information on how to contact you by electronic and paper mail. nuclear@12: nuclear@12: If the program does terminal interaction, make it output a short nuclear@12: notice like this when it starts in an interactive mode: nuclear@12: nuclear@12: Copyright (C) nuclear@12: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. nuclear@12: This is free software, and you are welcome to redistribute it nuclear@12: under certain conditions; type `show c' for details. nuclear@12: nuclear@12: The hypothetical commands `show w' and `show c' should show the appropriate nuclear@12: parts of the General Public License. Of course, your program's commands nuclear@12: might be different; for a GUI interface, you would use an "about box". nuclear@12: nuclear@12: You should also get your employer (if you work as a programmer) or school, nuclear@12: if any, to sign a "copyright disclaimer" for the program, if necessary. nuclear@12: For more information on this, and how to apply and follow the GNU GPL, see nuclear@12: . nuclear@12: nuclear@12: The GNU General Public License does not permit incorporating your program nuclear@12: into proprietary programs. If your program is a subroutine library, you nuclear@12: may consider it more useful to permit linking proprietary applications with nuclear@12: the library. If this is what you want to do, use the GNU Lesser General nuclear@12: Public License instead of this License. But first, please read nuclear@12: .
