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