nuclear@39: GNU GENERAL PUBLIC LICENSE nuclear@39: Version 3, 29 June 2007 nuclear@39: nuclear@39: Copyright (C) 2007 Free Software Foundation, Inc. nuclear@39: Everyone is permitted to copy and distribute verbatim copies nuclear@39: of this license document, but changing it is not allowed. nuclear@39: nuclear@39: Preamble nuclear@39: nuclear@39: The GNU General Public License is a free, copyleft license for nuclear@39: software and other kinds of works. nuclear@39: nuclear@39: The licenses for most software and other practical works are designed nuclear@39: to take away your freedom to share and change the works. By contrast, nuclear@39: the GNU General Public License is intended to guarantee your freedom to nuclear@39: share and change all versions of a program--to make sure it remains free nuclear@39: software for all its users. We, the Free Software Foundation, use the nuclear@39: GNU General Public License for most of our software; it applies also to nuclear@39: any other work released this way by its authors. You can apply it to nuclear@39: your programs, too. nuclear@39: nuclear@39: When we speak of free software, we are referring to freedom, not nuclear@39: price. Our General Public Licenses are designed to make sure that you nuclear@39: have the freedom to distribute copies of free software (and charge for nuclear@39: them if you wish), that you receive source code or can get it if you nuclear@39: want it, that you can change the software or use pieces of it in new nuclear@39: free programs, and that you know you can do these things. nuclear@39: nuclear@39: To protect your rights, we need to prevent others from denying you nuclear@39: these rights or asking you to surrender the rights. Therefore, you have nuclear@39: certain responsibilities if you distribute copies of the software, or if nuclear@39: you modify it: responsibilities to respect the freedom of others. nuclear@39: nuclear@39: For example, if you distribute copies of such a program, whether nuclear@39: gratis or for a fee, you must pass on to the recipients the same nuclear@39: freedoms that you received. You must make sure that they, too, receive nuclear@39: or can get the source code. And you must show them these terms so they nuclear@39: know their rights. nuclear@39: nuclear@39: Developers that use the GNU GPL protect your rights with two steps: nuclear@39: (1) assert copyright on the software, and (2) offer you this License nuclear@39: giving you legal permission to copy, distribute and/or modify it. nuclear@39: nuclear@39: For the developers' and authors' protection, the GPL clearly explains nuclear@39: that there is no warranty for this free software. For both users' and nuclear@39: authors' sake, the GPL requires that modified versions be marked as nuclear@39: changed, so that their problems will not be attributed erroneously to nuclear@39: authors of previous versions. nuclear@39: nuclear@39: Some devices are designed to deny users access to install or run nuclear@39: modified versions of the software inside them, although the manufacturer nuclear@39: can do so. This is fundamentally incompatible with the aim of nuclear@39: protecting users' freedom to change the software. The systematic nuclear@39: pattern of such abuse occurs in the area of products for individuals to nuclear@39: use, which is precisely where it is most unacceptable. Therefore, we nuclear@39: have designed this version of the GPL to prohibit the practice for those nuclear@39: products. If such problems arise substantially in other domains, we nuclear@39: stand ready to extend this provision to those domains in future versions nuclear@39: of the GPL, as needed to protect the freedom of users. nuclear@39: nuclear@39: Finally, every program is threatened constantly by software patents. nuclear@39: States should not allow patents to restrict development and use of nuclear@39: software on general-purpose computers, but in those that do, we wish to nuclear@39: avoid the special danger that patents applied to a free program could nuclear@39: make it effectively proprietary. To prevent this, the GPL assures that nuclear@39: patents cannot be used to render the program non-free. nuclear@39: nuclear@39: The precise terms and conditions for copying, distribution and nuclear@39: modification follow. nuclear@39: nuclear@39: TERMS AND CONDITIONS nuclear@39: nuclear@39: 0. Definitions. nuclear@39: nuclear@39: "This License" refers to version 3 of the GNU General Public License. nuclear@39: nuclear@39: "Copyright" also means copyright-like laws that apply to other kinds of nuclear@39: works, such as semiconductor masks. nuclear@39: nuclear@39: "The Program" refers to any copyrightable work licensed under this nuclear@39: License. Each licensee is addressed as "you". "Licensees" and nuclear@39: "recipients" may be individuals or organizations. nuclear@39: nuclear@39: To "modify" a work means to copy from or adapt all or part of the work nuclear@39: in a fashion requiring copyright permission, other than the making of an nuclear@39: exact copy. The resulting work is called a "modified version" of the nuclear@39: earlier work or a work "based on" the earlier work. nuclear@39: nuclear@39: A "covered work" means either the unmodified Program or a work based nuclear@39: on the Program. nuclear@39: nuclear@39: To "propagate" a work means to do anything with it that, without nuclear@39: permission, would make you directly or secondarily liable for nuclear@39: infringement under applicable copyright law, except executing it on a nuclear@39: computer or modifying a private copy. Propagation includes copying, nuclear@39: distribution (with or without modification), making available to the nuclear@39: public, and in some countries other activities as well. nuclear@39: nuclear@39: To "convey" a work means any kind of propagation that enables other nuclear@39: parties to make or receive copies. Mere interaction with a user through nuclear@39: a computer network, with no transfer of a copy, is not conveying. nuclear@39: nuclear@39: An interactive user interface displays "Appropriate Legal Notices" nuclear@39: to the extent that it includes a convenient and prominently visible nuclear@39: feature that (1) displays an appropriate copyright notice, and (2) nuclear@39: tells the user that there is no warranty for the work (except to the nuclear@39: extent that warranties are provided), that licensees may convey the nuclear@39: work under this License, and how to view a copy of this License. If nuclear@39: the interface presents a list of user commands or options, such as a nuclear@39: menu, a prominent item in the list meets this criterion. nuclear@39: nuclear@39: 1. Source Code. nuclear@39: nuclear@39: The "source code" for a work means the preferred form of the work nuclear@39: for making modifications to it. "Object code" means any non-source nuclear@39: form of a work. nuclear@39: nuclear@39: A "Standard Interface" means an interface that either is an official nuclear@39: standard defined by a recognized standards body, or, in the case of nuclear@39: interfaces specified for a particular programming language, one that nuclear@39: is widely used among developers working in that language. nuclear@39: nuclear@39: The "System Libraries" of an executable work include anything, other nuclear@39: than the work as a whole, that (a) is included in the normal form of nuclear@39: packaging a Major Component, but which is not part of that Major nuclear@39: Component, and (b) serves only to enable use of the work with that nuclear@39: Major Component, or to implement a Standard Interface for which an nuclear@39: implementation is available to the public in source code form. A nuclear@39: "Major Component", in this context, means a major essential component nuclear@39: (kernel, window system, and so on) of the specific operating system nuclear@39: (if any) on which the executable work runs, or a compiler used to nuclear@39: produce the work, or an object code interpreter used to run it. nuclear@39: nuclear@39: The "Corresponding Source" for a work in object code form means all nuclear@39: the source code needed to generate, install, and (for an executable nuclear@39: work) run the object code and to modify the work, including scripts to nuclear@39: control those activities. However, it does not include the work's nuclear@39: System Libraries, or general-purpose tools or generally available free nuclear@39: programs which are used unmodified in performing those activities but nuclear@39: which are not part of the work. For example, Corresponding Source nuclear@39: includes interface definition files associated with source files for nuclear@39: the work, and the source code for shared libraries and dynamically nuclear@39: linked subprograms that the work is specifically designed to require, nuclear@39: such as by intimate data communication or control flow between those nuclear@39: subprograms and other parts of the work. nuclear@39: nuclear@39: The Corresponding Source need not include anything that users nuclear@39: can regenerate automatically from other parts of the Corresponding nuclear@39: Source. nuclear@39: nuclear@39: The Corresponding Source for a work in source code form is that nuclear@39: same work. nuclear@39: nuclear@39: 2. Basic Permissions. nuclear@39: nuclear@39: All rights granted under this License are granted for the term of nuclear@39: copyright on the Program, and are irrevocable provided the stated nuclear@39: conditions are met. This License explicitly affirms your unlimited nuclear@39: permission to run the unmodified Program. The output from running a nuclear@39: covered work is covered by this License only if the output, given its nuclear@39: content, constitutes a covered work. This License acknowledges your nuclear@39: rights of fair use or other equivalent, as provided by copyright law. nuclear@39: nuclear@39: You may make, run and propagate covered works that you do not nuclear@39: convey, without conditions so long as your license otherwise remains nuclear@39: in force. You may convey covered works to others for the sole purpose nuclear@39: of having them make modifications exclusively for you, or provide you nuclear@39: with facilities for running those works, provided that you comply with nuclear@39: the terms of this License in conveying all material for which you do nuclear@39: not control copyright. Those thus making or running the covered works nuclear@39: for you must do so exclusively on your behalf, under your direction nuclear@39: and control, on terms that prohibit them from making any copies of nuclear@39: your copyrighted material outside their relationship with you. nuclear@39: nuclear@39: Conveying under any other circumstances is permitted solely under nuclear@39: the conditions stated below. Sublicensing is not allowed; section 10 nuclear@39: makes it unnecessary. nuclear@39: nuclear@39: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. nuclear@39: nuclear@39: No covered work shall be deemed part of an effective technological nuclear@39: measure under any applicable law fulfilling obligations under article nuclear@39: 11 of the WIPO copyright treaty adopted on 20 December 1996, or nuclear@39: similar laws prohibiting or restricting circumvention of such nuclear@39: measures. nuclear@39: nuclear@39: When you convey a covered work, you waive any legal power to forbid nuclear@39: circumvention of technological measures to the extent such circumvention nuclear@39: is effected by exercising rights under this License with respect to nuclear@39: the covered work, and you disclaim any intention to limit operation or nuclear@39: modification of the work as a means of enforcing, against the work's nuclear@39: users, your or third parties' legal rights to forbid circumvention of nuclear@39: technological measures. nuclear@39: nuclear@39: 4. Conveying Verbatim Copies. nuclear@39: nuclear@39: You may convey verbatim copies of the Program's source code as you nuclear@39: receive it, in any medium, provided that you conspicuously and nuclear@39: appropriately publish on each copy an appropriate copyright notice; nuclear@39: keep intact all notices stating that this License and any nuclear@39: non-permissive terms added in accord with section 7 apply to the code; nuclear@39: keep intact all notices of the absence of any warranty; and give all nuclear@39: recipients a copy of this License along with the Program. nuclear@39: nuclear@39: You may charge any price or no price for each copy that you convey, nuclear@39: and you may offer support or warranty protection for a fee. nuclear@39: nuclear@39: 5. Conveying Modified Source Versions. nuclear@39: nuclear@39: You may convey a work based on the Program, or the modifications to nuclear@39: produce it from the Program, in the form of source code under the nuclear@39: terms of section 4, provided that you also meet all of these conditions: nuclear@39: nuclear@39: a) The work must carry prominent notices stating that you modified nuclear@39: it, and giving a relevant date. nuclear@39: nuclear@39: b) The work must carry prominent notices stating that it is nuclear@39: released under this License and any conditions added under section nuclear@39: 7. This requirement modifies the requirement in section 4 to nuclear@39: "keep intact all notices". nuclear@39: nuclear@39: c) You must license the entire work, as a whole, under this nuclear@39: License to anyone who comes into possession of a copy. This nuclear@39: License will therefore apply, along with any applicable section 7 nuclear@39: additional terms, to the whole of the work, and all its parts, nuclear@39: regardless of how they are packaged. This License gives no nuclear@39: permission to license the work in any other way, but it does not nuclear@39: invalidate such permission if you have separately received it. nuclear@39: nuclear@39: d) If the work has interactive user interfaces, each must display nuclear@39: Appropriate Legal Notices; however, if the Program has interactive nuclear@39: interfaces that do not display Appropriate Legal Notices, your nuclear@39: work need not make them do so. nuclear@39: nuclear@39: A compilation of a covered work with other separate and independent nuclear@39: works, which are not by their nature extensions of the covered work, nuclear@39: and which are not combined with it such as to form a larger program, nuclear@39: in or on a volume of a storage or distribution medium, is called an nuclear@39: "aggregate" if the compilation and its resulting copyright are not nuclear@39: used to limit the access or legal rights of the compilation's users nuclear@39: beyond what the individual works permit. Inclusion of a covered work nuclear@39: in an aggregate does not cause this License to apply to the other nuclear@39: parts of the aggregate. nuclear@39: nuclear@39: 6. Conveying Non-Source Forms. nuclear@39: nuclear@39: You may convey a covered work in object code form under the terms nuclear@39: of sections 4 and 5, provided that you also convey the nuclear@39: machine-readable Corresponding Source under the terms of this License, nuclear@39: in one of these ways: nuclear@39: nuclear@39: a) Convey the object code in, or embodied in, a physical product nuclear@39: (including a physical distribution medium), accompanied by the nuclear@39: Corresponding Source fixed on a durable physical medium nuclear@39: customarily used for software interchange. nuclear@39: nuclear@39: b) Convey the object code in, or embodied in, a physical product nuclear@39: (including a physical distribution medium), accompanied by a nuclear@39: written offer, valid for at least three years and valid for as nuclear@39: long as you offer spare parts or customer support for that product nuclear@39: model, to give anyone who possesses the object code either (1) a nuclear@39: copy of the Corresponding Source for all the software in the nuclear@39: product that is covered by this License, on a durable physical nuclear@39: medium customarily used for software interchange, for a price no nuclear@39: more than your reasonable cost of physically performing this nuclear@39: conveying of source, or (2) access to copy the nuclear@39: Corresponding Source from a network server at no charge. nuclear@39: nuclear@39: c) Convey individual copies of the object code with a copy of the nuclear@39: written offer to provide the Corresponding Source. This nuclear@39: alternative is allowed only occasionally and noncommercially, and nuclear@39: only if you received the object code with such an offer, in accord nuclear@39: with subsection 6b. nuclear@39: nuclear@39: d) Convey the object code by offering access from a designated nuclear@39: place (gratis or for a charge), and offer equivalent access to the nuclear@39: Corresponding Source in the same way through the same place at no nuclear@39: further charge. You need not require recipients to copy the nuclear@39: Corresponding Source along with the object code. If the place to nuclear@39: copy the object code is a network server, the Corresponding Source nuclear@39: may be on a different server (operated by you or a third party) nuclear@39: that supports equivalent copying facilities, provided you maintain nuclear@39: clear directions next to the object code saying where to find the nuclear@39: Corresponding Source. Regardless of what server hosts the nuclear@39: Corresponding Source, you remain obligated to ensure that it is nuclear@39: available for as long as needed to satisfy these requirements. nuclear@39: nuclear@39: e) Convey the object code using peer-to-peer transmission, provided nuclear@39: you inform other peers where the object code and Corresponding nuclear@39: Source of the work are being offered to the general public at no nuclear@39: charge under subsection 6d. nuclear@39: nuclear@39: A separable portion of the object code, whose source code is excluded nuclear@39: from the Corresponding Source as a System Library, need not be nuclear@39: included in conveying the object code work. nuclear@39: nuclear@39: A "User Product" is either (1) a "consumer product", which means any nuclear@39: tangible personal property which is normally used for personal, family, nuclear@39: or household purposes, or (2) anything designed or sold for incorporation nuclear@39: into a dwelling. In determining whether a product is a consumer product, nuclear@39: doubtful cases shall be resolved in favor of coverage. For a particular nuclear@39: product received by a particular user, "normally used" refers to a nuclear@39: typical or common use of that class of product, regardless of the status nuclear@39: of the particular user or of the way in which the particular user nuclear@39: actually uses, or expects or is expected to use, the product. A product nuclear@39: is a consumer product regardless of whether the product has substantial nuclear@39: commercial, industrial or non-consumer uses, unless such uses represent nuclear@39: the only significant mode of use of the product. nuclear@39: nuclear@39: "Installation Information" for a User Product means any methods, nuclear@39: procedures, authorization keys, or other information required to install nuclear@39: and execute modified versions of a covered work in that User Product from nuclear@39: a modified version of its Corresponding Source. The information must nuclear@39: suffice to ensure that the continued functioning of the modified object nuclear@39: code is in no case prevented or interfered with solely because nuclear@39: modification has been made. nuclear@39: nuclear@39: If you convey an object code work under this section in, or with, or nuclear@39: specifically for use in, a User Product, and the conveying occurs as nuclear@39: part of a transaction in which the right of possession and use of the nuclear@39: User Product is transferred to the recipient in perpetuity or for a nuclear@39: fixed term (regardless of how the transaction is characterized), the nuclear@39: Corresponding Source conveyed under this section must be accompanied nuclear@39: by the Installation Information. But this requirement does not apply nuclear@39: if neither you nor any third party retains the ability to install nuclear@39: modified object code on the User Product (for example, the work has nuclear@39: been installed in ROM). nuclear@39: nuclear@39: The requirement to provide Installation Information does not include a nuclear@39: requirement to continue to provide support service, warranty, or updates nuclear@39: for a work that has been modified or installed by the recipient, or for nuclear@39: the User Product in which it has been modified or installed. Access to a nuclear@39: network may be denied when the modification itself materially and nuclear@39: adversely affects the operation of the network or violates the rules and nuclear@39: protocols for communication across the network. nuclear@39: nuclear@39: Corresponding Source conveyed, and Installation Information provided, nuclear@39: in accord with this section must be in a format that is publicly nuclear@39: documented (and with an implementation available to the public in nuclear@39: source code form), and must require no special password or key for nuclear@39: unpacking, reading or copying. nuclear@39: nuclear@39: 7. Additional Terms. nuclear@39: nuclear@39: "Additional permissions" are terms that supplement the terms of this nuclear@39: License by making exceptions from one or more of its conditions. nuclear@39: Additional permissions that are applicable to the entire Program shall nuclear@39: be treated as though they were included in this License, to the extent nuclear@39: that they are valid under applicable law. If additional permissions nuclear@39: apply only to part of the Program, that part may be used separately nuclear@39: under those permissions, but the entire Program remains governed by nuclear@39: this License without regard to the additional permissions. nuclear@39: nuclear@39: When you convey a copy of a covered work, you may at your option nuclear@39: remove any additional permissions from that copy, or from any part of nuclear@39: it. (Additional permissions may be written to require their own nuclear@39: removal in certain cases when you modify the work.) You may place nuclear@39: additional permissions on material, added by you to a covered work, nuclear@39: for which you have or can give appropriate copyright permission. nuclear@39: nuclear@39: Notwithstanding any other provision of this License, for material you nuclear@39: add to a covered work, you may (if authorized by the copyright holders of nuclear@39: that material) supplement the terms of this License with terms: nuclear@39: nuclear@39: a) Disclaiming warranty or limiting liability differently from the nuclear@39: terms of sections 15 and 16 of this License; or nuclear@39: nuclear@39: b) Requiring preservation of specified reasonable legal notices or nuclear@39: author attributions in that material or in the Appropriate Legal nuclear@39: Notices displayed by works containing it; or nuclear@39: nuclear@39: c) Prohibiting misrepresentation of the origin of that material, or nuclear@39: requiring that modified versions of such material be marked in nuclear@39: reasonable ways as different from the original version; or nuclear@39: nuclear@39: d) Limiting the use for publicity purposes of names of licensors or nuclear@39: authors of the material; or nuclear@39: nuclear@39: e) Declining to grant rights under trademark law for use of some nuclear@39: trade names, trademarks, or service marks; or nuclear@39: nuclear@39: f) Requiring indemnification of licensors and authors of that nuclear@39: material by anyone who conveys the material (or modified versions of nuclear@39: it) with contractual assumptions of liability to the recipient, for nuclear@39: any liability that these contractual assumptions directly impose on nuclear@39: those licensors and authors. nuclear@39: nuclear@39: All other non-permissive additional terms are considered "further nuclear@39: restrictions" within the meaning of section 10. If the Program as you nuclear@39: received it, or any part of it, contains a notice stating that it is nuclear@39: governed by this License along with a term that is a further nuclear@39: restriction, you may remove that term. If a license document contains nuclear@39: a further restriction but permits relicensing or conveying under this nuclear@39: License, you may add to a covered work material governed by the terms nuclear@39: of that license document, provided that the further restriction does nuclear@39: not survive such relicensing or conveying. nuclear@39: nuclear@39: If you add terms to a covered work in accord with this section, you nuclear@39: must place, in the relevant source files, a statement of the nuclear@39: additional terms that apply to those files, or a notice indicating nuclear@39: where to find the applicable terms. nuclear@39: nuclear@39: Additional terms, permissive or non-permissive, may be stated in the nuclear@39: form of a separately written license, or stated as exceptions; nuclear@39: the above requirements apply either way. nuclear@39: nuclear@39: 8. Termination. nuclear@39: nuclear@39: You may not propagate or modify a covered work except as expressly nuclear@39: provided under this License. Any attempt otherwise to propagate or nuclear@39: modify it is void, and will automatically terminate your rights under nuclear@39: this License (including any patent licenses granted under the third nuclear@39: paragraph of section 11). nuclear@39: nuclear@39: However, if you cease all violation of this License, then your nuclear@39: license from a particular copyright holder is reinstated (a) nuclear@39: provisionally, unless and until the copyright holder explicitly and nuclear@39: finally terminates your license, and (b) permanently, if the copyright nuclear@39: holder fails to notify you of the violation by some reasonable means nuclear@39: prior to 60 days after the cessation. nuclear@39: nuclear@39: Moreover, your license from a particular copyright holder is nuclear@39: reinstated permanently if the copyright holder notifies you of the nuclear@39: violation by some reasonable means, this is the first time you have nuclear@39: received notice of violation of this License (for any work) from that nuclear@39: copyright holder, and you cure the violation prior to 30 days after nuclear@39: your receipt of the notice. nuclear@39: nuclear@39: Termination of your rights under this section does not terminate the nuclear@39: licenses of parties who have received copies or rights from you under nuclear@39: this License. If your rights have been terminated and not permanently nuclear@39: reinstated, you do not qualify to receive new licenses for the same nuclear@39: material under section 10. nuclear@39: nuclear@39: 9. Acceptance Not Required for Having Copies. nuclear@39: nuclear@39: You are not required to accept this License in order to receive or nuclear@39: run a copy of the Program. Ancillary propagation of a covered work nuclear@39: occurring solely as a consequence of using peer-to-peer transmission nuclear@39: to receive a copy likewise does not require acceptance. However, nuclear@39: nothing other than this License grants you permission to propagate or nuclear@39: modify any covered work. These actions infringe copyright if you do nuclear@39: not accept this License. Therefore, by modifying or propagating a nuclear@39: covered work, you indicate your acceptance of this License to do so. nuclear@39: nuclear@39: 10. Automatic Licensing of Downstream Recipients. nuclear@39: nuclear@39: Each time you convey a covered work, the recipient automatically nuclear@39: receives a license from the original licensors, to run, modify and nuclear@39: propagate that work, subject to this License. You are not responsible nuclear@39: for enforcing compliance by third parties with this License. nuclear@39: nuclear@39: An "entity transaction" is a transaction transferring control of an nuclear@39: organization, or substantially all assets of one, or subdividing an nuclear@39: organization, or merging organizations. If propagation of a covered nuclear@39: work results from an entity transaction, each party to that nuclear@39: transaction who receives a copy of the work also receives whatever nuclear@39: licenses to the work the party's predecessor in interest had or could nuclear@39: give under the previous paragraph, plus a right to possession of the nuclear@39: Corresponding Source of the work from the predecessor in interest, if nuclear@39: the predecessor has it or can get it with reasonable efforts. nuclear@39: nuclear@39: You may not impose any further restrictions on the exercise of the nuclear@39: rights granted or affirmed under this License. For example, you may nuclear@39: not impose a license fee, royalty, or other charge for exercise of nuclear@39: rights granted under this License, and you may not initiate litigation nuclear@39: (including a cross-claim or counterclaim in a lawsuit) alleging that nuclear@39: any patent claim is infringed by making, using, selling, offering for nuclear@39: sale, or importing the Program or any portion of it. nuclear@39: nuclear@39: 11. Patents. nuclear@39: nuclear@39: A "contributor" is a copyright holder who authorizes use under this nuclear@39: License of the Program or a work on which the Program is based. The nuclear@39: work thus licensed is called the contributor's "contributor version". nuclear@39: nuclear@39: A contributor's "essential patent claims" are all patent claims nuclear@39: owned or controlled by the contributor, whether already acquired or nuclear@39: hereafter acquired, that would be infringed by some manner, permitted nuclear@39: by this License, of making, using, or selling its contributor version, nuclear@39: but do not include claims that would be infringed only as a nuclear@39: consequence of further modification of the contributor version. For nuclear@39: purposes of this definition, "control" includes the right to grant nuclear@39: patent sublicenses in a manner consistent with the requirements of nuclear@39: this License. nuclear@39: nuclear@39: Each contributor grants you a non-exclusive, worldwide, royalty-free nuclear@39: patent license under the contributor's essential patent claims, to nuclear@39: make, use, sell, offer for sale, import and otherwise run, modify and nuclear@39: propagate the contents of its contributor version. nuclear@39: nuclear@39: In the following three paragraphs, a "patent license" is any express nuclear@39: agreement or commitment, however denominated, not to enforce a patent nuclear@39: (such as an express permission to practice a patent or covenant not to nuclear@39: sue for patent infringement). To "grant" such a patent license to a nuclear@39: party means to make such an agreement or commitment not to enforce a nuclear@39: patent against the party. nuclear@39: nuclear@39: If you convey a covered work, knowingly relying on a patent license, nuclear@39: and the Corresponding Source of the work is not available for anyone nuclear@39: to copy, free of charge and under the terms of this License, through a nuclear@39: publicly available network server or other readily accessible means, nuclear@39: then you must either (1) cause the Corresponding Source to be so nuclear@39: available, or (2) arrange to deprive yourself of the benefit of the nuclear@39: patent license for this particular work, or (3) arrange, in a manner nuclear@39: consistent with the requirements of this License, to extend the patent nuclear@39: license to downstream recipients. "Knowingly relying" means you have nuclear@39: actual knowledge that, but for the patent license, your conveying the nuclear@39: covered work in a country, or your recipient's use of the covered work nuclear@39: in a country, would infringe one or more identifiable patents in that nuclear@39: country that you have reason to believe are valid. nuclear@39: nuclear@39: If, pursuant to or in connection with a single transaction or nuclear@39: arrangement, you convey, or propagate by procuring conveyance of, a nuclear@39: covered work, and grant a patent license to some of the parties nuclear@39: receiving the covered work authorizing them to use, propagate, modify nuclear@39: or convey a specific copy of the covered work, then the patent license nuclear@39: you grant is automatically extended to all recipients of the covered nuclear@39: work and works based on it. nuclear@39: nuclear@39: A patent license is "discriminatory" if it does not include within nuclear@39: the scope of its coverage, prohibits the exercise of, or is nuclear@39: conditioned on the non-exercise of one or more of the rights that are nuclear@39: specifically granted under this License. You may not convey a covered nuclear@39: work if you are a party to an arrangement with a third party that is nuclear@39: in the business of distributing software, under which you make payment nuclear@39: to the third party based on the extent of your activity of conveying nuclear@39: the work, and under which the third party grants, to any of the nuclear@39: parties who would receive the covered work from you, a discriminatory nuclear@39: patent license (a) in connection with copies of the covered work nuclear@39: conveyed by you (or copies made from those copies), or (b) primarily nuclear@39: for and in connection with specific products or compilations that nuclear@39: contain the covered work, unless you entered into that arrangement, nuclear@39: or that patent license was granted, prior to 28 March 2007. nuclear@39: nuclear@39: Nothing in this License shall be construed as excluding or limiting nuclear@39: any implied license or other defenses to infringement that may nuclear@39: otherwise be available to you under applicable patent law. nuclear@39: nuclear@39: 12. No Surrender of Others' Freedom. nuclear@39: nuclear@39: If conditions are imposed on you (whether by court order, agreement or nuclear@39: otherwise) that contradict the conditions of this License, they do not nuclear@39: excuse you from the conditions of this License. If you cannot convey a nuclear@39: covered work so as to satisfy simultaneously your obligations under this nuclear@39: License and any other pertinent obligations, then as a consequence you may nuclear@39: not convey it at all. For example, if you agree to terms that obligate you nuclear@39: to collect a royalty for further conveying from those to whom you convey nuclear@39: the Program, the only way you could satisfy both those terms and this nuclear@39: License would be to refrain entirely from conveying the Program. nuclear@39: nuclear@39: 13. Use with the GNU Affero General Public License. nuclear@39: nuclear@39: Notwithstanding any other provision of this License, you have nuclear@39: permission to link or combine any covered work with a work licensed nuclear@39: under version 3 of the GNU Affero General Public License into a single nuclear@39: combined work, and to convey the resulting work. The terms of this nuclear@39: License will continue to apply to the part which is the covered work, nuclear@39: but the special requirements of the GNU Affero General Public License, nuclear@39: section 13, concerning interaction through a network will apply to the nuclear@39: combination as such. nuclear@39: nuclear@39: 14. Revised Versions of this License. nuclear@39: nuclear@39: The Free Software Foundation may publish revised and/or new versions of nuclear@39: the GNU General Public License from time to time. Such new versions will nuclear@39: be similar in spirit to the present version, but may differ in detail to nuclear@39: address new problems or concerns. nuclear@39: nuclear@39: Each version is given a distinguishing version number. If the nuclear@39: Program specifies that a certain numbered version of the GNU General nuclear@39: Public License "or any later version" applies to it, you have the nuclear@39: option of following the terms and conditions either of that numbered nuclear@39: version or of any later version published by the Free Software nuclear@39: Foundation. If the Program does not specify a version number of the nuclear@39: GNU General Public License, you may choose any version ever published nuclear@39: by the Free Software Foundation. nuclear@39: nuclear@39: If the Program specifies that a proxy can decide which future nuclear@39: versions of the GNU General Public License can be used, that proxy's nuclear@39: public statement of acceptance of a version permanently authorizes you nuclear@39: to choose that version for the Program. nuclear@39: nuclear@39: Later license versions may give you additional or different nuclear@39: permissions. However, no additional obligations are imposed on any nuclear@39: author or copyright holder as a result of your choosing to follow a nuclear@39: later version. nuclear@39: nuclear@39: 15. Disclaimer of Warranty. nuclear@39: nuclear@39: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY nuclear@39: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT nuclear@39: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY nuclear@39: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, nuclear@39: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR nuclear@39: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM nuclear@39: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF nuclear@39: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. nuclear@39: nuclear@39: 16. Limitation of Liability. nuclear@39: nuclear@39: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING nuclear@39: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS nuclear@39: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY nuclear@39: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE nuclear@39: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF nuclear@39: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD nuclear@39: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), nuclear@39: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF nuclear@39: SUCH DAMAGES. nuclear@39: nuclear@39: 17. Interpretation of Sections 15 and 16. nuclear@39: nuclear@39: If the disclaimer of warranty and limitation of liability provided nuclear@39: above cannot be given local legal effect according to their terms, nuclear@39: reviewing courts shall apply local law that most closely approximates nuclear@39: an absolute waiver of all civil liability in connection with the nuclear@39: Program, unless a warranty or assumption of liability accompanies a nuclear@39: copy of the Program in return for a fee. nuclear@39: nuclear@39: END OF TERMS AND CONDITIONS nuclear@39: nuclear@39: How to Apply These Terms to Your New Programs nuclear@39: nuclear@39: If you develop a new program, and you want it to be of the greatest nuclear@39: possible use to the public, the best way to achieve this is to make it nuclear@39: free software which everyone can redistribute and change under these terms. nuclear@39: nuclear@39: To do so, attach the following notices to the program. It is safest nuclear@39: to attach them to the start of each source file to most effectively nuclear@39: state the exclusion of warranty; and each file should have at least nuclear@39: the "copyright" line and a pointer to where the full notice is found. nuclear@39: nuclear@39: nuclear@39: Copyright (C) nuclear@39: nuclear@39: This program is free software: you can redistribute it and/or modify nuclear@39: it under the terms of the GNU General Public License as published by nuclear@39: the Free Software Foundation, either version 3 of the License, or nuclear@39: (at your option) any later version. nuclear@39: nuclear@39: This program is distributed in the hope that it will be useful, nuclear@39: but WITHOUT ANY WARRANTY; without even the implied warranty of nuclear@39: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the nuclear@39: GNU General Public License for more details. nuclear@39: nuclear@39: You should have received a copy of the GNU General Public License nuclear@39: along with this program. If not, see . nuclear@39: nuclear@39: Also add information on how to contact you by electronic and paper mail. nuclear@39: nuclear@39: If the program does terminal interaction, make it output a short nuclear@39: notice like this when it starts in an interactive mode: nuclear@39: nuclear@39: Copyright (C) nuclear@39: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. nuclear@39: This is free software, and you are welcome to redistribute it nuclear@39: under certain conditions; type `show c' for details. nuclear@39: nuclear@39: The hypothetical commands `show w' and `show c' should show the appropriate nuclear@39: parts of the General Public License. Of course, your program's commands nuclear@39: might be different; for a GUI interface, you would use an "about box". nuclear@39: nuclear@39: You should also get your employer (if you work as a programmer) or school, nuclear@39: if any, to sign a "copyright disclaimer" for the program, if necessary. nuclear@39: For more information on this, and how to apply and follow the GNU GPL, see nuclear@39: . nuclear@39: nuclear@39: The GNU General Public License does not permit incorporating your program nuclear@39: into proprietary programs. If your program is a subroutine library, you nuclear@39: may consider it more useful to permit linking proprietary applications with nuclear@39: the library. If this is what you want to do, use the GNU Lesser General nuclear@39: Public License instead of this License. But first, please read nuclear@39: .
