nuclear@61: GNU GENERAL PUBLIC LICENSE nuclear@61: Version 3, 29 June 2007 nuclear@61: nuclear@61: Copyright (C) 2007 Free Software Foundation, Inc. nuclear@61: Everyone is permitted to copy and distribute verbatim copies nuclear@61: of this license document, but changing it is not allowed. nuclear@61: nuclear@61: Preamble nuclear@61: nuclear@61: The GNU General Public License is a free, copyleft license for nuclear@61: software and other kinds of works. nuclear@61: nuclear@61: The licenses for most software and other practical works are designed nuclear@61: to take away your freedom to share and change the works. By contrast, nuclear@61: the GNU General Public License is intended to guarantee your freedom to nuclear@61: share and change all versions of a program--to make sure it remains free nuclear@61: software for all its users. We, the Free Software Foundation, use the nuclear@61: GNU General Public License for most of our software; it applies also to nuclear@61: any other work released this way by its authors. You can apply it to nuclear@61: your programs, too. nuclear@61: nuclear@61: When we speak of free software, we are referring to freedom, not nuclear@61: price. Our General Public Licenses are designed to make sure that you nuclear@61: have the freedom to distribute copies of free software (and charge for nuclear@61: them if you wish), that you receive source code or can get it if you nuclear@61: want it, that you can change the software or use pieces of it in new nuclear@61: free programs, and that you know you can do these things. nuclear@61: nuclear@61: To protect your rights, we need to prevent others from denying you nuclear@61: these rights or asking you to surrender the rights. Therefore, you have nuclear@61: certain responsibilities if you distribute copies of the software, or if nuclear@61: you modify it: responsibilities to respect the freedom of others. nuclear@61: nuclear@61: For example, if you distribute copies of such a program, whether nuclear@61: gratis or for a fee, you must pass on to the recipients the same nuclear@61: freedoms that you received. You must make sure that they, too, receive nuclear@61: or can get the source code. And you must show them these terms so they nuclear@61: know their rights. nuclear@61: nuclear@61: Developers that use the GNU GPL protect your rights with two steps: nuclear@61: (1) assert copyright on the software, and (2) offer you this License nuclear@61: giving you legal permission to copy, distribute and/or modify it. nuclear@61: nuclear@61: For the developers' and authors' protection, the GPL clearly explains nuclear@61: that there is no warranty for this free software. For both users' and nuclear@61: authors' sake, the GPL requires that modified versions be marked as nuclear@61: changed, so that their problems will not be attributed erroneously to nuclear@61: authors of previous versions. nuclear@61: nuclear@61: Some devices are designed to deny users access to install or run nuclear@61: modified versions of the software inside them, although the manufacturer nuclear@61: can do so. This is fundamentally incompatible with the aim of nuclear@61: protecting users' freedom to change the software. The systematic nuclear@61: pattern of such abuse occurs in the area of products for individuals to nuclear@61: use, which is precisely where it is most unacceptable. Therefore, we nuclear@61: have designed this version of the GPL to prohibit the practice for those nuclear@61: products. If such problems arise substantially in other domains, we nuclear@61: stand ready to extend this provision to those domains in future versions nuclear@61: of the GPL, as needed to protect the freedom of users. nuclear@61: nuclear@61: Finally, every program is threatened constantly by software patents. nuclear@61: States should not allow patents to restrict development and use of nuclear@61: software on general-purpose computers, but in those that do, we wish to nuclear@61: avoid the special danger that patents applied to a free program could nuclear@61: make it effectively proprietary. To prevent this, the GPL assures that nuclear@61: patents cannot be used to render the program non-free. nuclear@61: nuclear@61: The precise terms and conditions for copying, distribution and nuclear@61: modification follow. nuclear@61: nuclear@61: TERMS AND CONDITIONS nuclear@61: nuclear@61: 0. Definitions. nuclear@61: nuclear@61: "This License" refers to version 3 of the GNU General Public License. nuclear@61: nuclear@61: "Copyright" also means copyright-like laws that apply to other kinds of nuclear@61: works, such as semiconductor masks. nuclear@61: nuclear@61: "The Program" refers to any copyrightable work licensed under this nuclear@61: License. Each licensee is addressed as "you". "Licensees" and nuclear@61: "recipients" may be individuals or organizations. nuclear@61: nuclear@61: To "modify" a work means to copy from or adapt all or part of the work nuclear@61: in a fashion requiring copyright permission, other than the making of an nuclear@61: exact copy. The resulting work is called a "modified version" of the nuclear@61: earlier work or a work "based on" the earlier work. nuclear@61: nuclear@61: A "covered work" means either the unmodified Program or a work based nuclear@61: on the Program. nuclear@61: nuclear@61: To "propagate" a work means to do anything with it that, without nuclear@61: permission, would make you directly or secondarily liable for nuclear@61: infringement under applicable copyright law, except executing it on a nuclear@61: computer or modifying a private copy. Propagation includes copying, nuclear@61: distribution (with or without modification), making available to the nuclear@61: public, and in some countries other activities as well. nuclear@61: nuclear@61: To "convey" a work means any kind of propagation that enables other nuclear@61: parties to make or receive copies. Mere interaction with a user through nuclear@61: a computer network, with no transfer of a copy, is not conveying. nuclear@61: nuclear@61: An interactive user interface displays "Appropriate Legal Notices" nuclear@61: to the extent that it includes a convenient and prominently visible nuclear@61: feature that (1) displays an appropriate copyright notice, and (2) nuclear@61: tells the user that there is no warranty for the work (except to the nuclear@61: extent that warranties are provided), that licensees may convey the nuclear@61: work under this License, and how to view a copy of this License. If nuclear@61: the interface presents a list of user commands or options, such as a nuclear@61: menu, a prominent item in the list meets this criterion. nuclear@61: nuclear@61: 1. Source Code. nuclear@61: nuclear@61: The "source code" for a work means the preferred form of the work nuclear@61: for making modifications to it. "Object code" means any non-source nuclear@61: form of a work. nuclear@61: nuclear@61: A "Standard Interface" means an interface that either is an official nuclear@61: standard defined by a recognized standards body, or, in the case of nuclear@61: interfaces specified for a particular programming language, one that nuclear@61: is widely used among developers working in that language. nuclear@61: nuclear@61: The "System Libraries" of an executable work include anything, other nuclear@61: than the work as a whole, that (a) is included in the normal form of nuclear@61: packaging a Major Component, but which is not part of that Major nuclear@61: Component, and (b) serves only to enable use of the work with that nuclear@61: Major Component, or to implement a Standard Interface for which an nuclear@61: implementation is available to the public in source code form. A nuclear@61: "Major Component", in this context, means a major essential component nuclear@61: (kernel, window system, and so on) of the specific operating system nuclear@61: (if any) on which the executable work runs, or a compiler used to nuclear@61: produce the work, or an object code interpreter used to run it. nuclear@61: nuclear@61: The "Corresponding Source" for a work in object code form means all nuclear@61: the source code needed to generate, install, and (for an executable nuclear@61: work) run the object code and to modify the work, including scripts to nuclear@61: control those activities. However, it does not include the work's nuclear@61: System Libraries, or general-purpose tools or generally available free nuclear@61: programs which are used unmodified in performing those activities but nuclear@61: which are not part of the work. For example, Corresponding Source nuclear@61: includes interface definition files associated with source files for nuclear@61: the work, and the source code for shared libraries and dynamically nuclear@61: linked subprograms that the work is specifically designed to require, nuclear@61: such as by intimate data communication or control flow between those nuclear@61: subprograms and other parts of the work. nuclear@61: nuclear@61: The Corresponding Source need not include anything that users nuclear@61: can regenerate automatically from other parts of the Corresponding nuclear@61: Source. nuclear@61: nuclear@61: The Corresponding Source for a work in source code form is that nuclear@61: same work. nuclear@61: nuclear@61: 2. Basic Permissions. nuclear@61: nuclear@61: All rights granted under this License are granted for the term of nuclear@61: copyright on the Program, and are irrevocable provided the stated nuclear@61: conditions are met. This License explicitly affirms your unlimited nuclear@61: permission to run the unmodified Program. The output from running a nuclear@61: covered work is covered by this License only if the output, given its nuclear@61: content, constitutes a covered work. This License acknowledges your nuclear@61: rights of fair use or other equivalent, as provided by copyright law. nuclear@61: nuclear@61: You may make, run and propagate covered works that you do not nuclear@61: convey, without conditions so long as your license otherwise remains nuclear@61: in force. You may convey covered works to others for the sole purpose nuclear@61: of having them make modifications exclusively for you, or provide you nuclear@61: with facilities for running those works, provided that you comply with nuclear@61: the terms of this License in conveying all material for which you do nuclear@61: not control copyright. Those thus making or running the covered works nuclear@61: for you must do so exclusively on your behalf, under your direction nuclear@61: and control, on terms that prohibit them from making any copies of nuclear@61: your copyrighted material outside their relationship with you. nuclear@61: nuclear@61: Conveying under any other circumstances is permitted solely under nuclear@61: the conditions stated below. Sublicensing is not allowed; section 10 nuclear@61: makes it unnecessary. nuclear@61: nuclear@61: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. nuclear@61: nuclear@61: No covered work shall be deemed part of an effective technological nuclear@61: measure under any applicable law fulfilling obligations under article nuclear@61: 11 of the WIPO copyright treaty adopted on 20 December 1996, or nuclear@61: similar laws prohibiting or restricting circumvention of such nuclear@61: measures. nuclear@61: nuclear@61: When you convey a covered work, you waive any legal power to forbid nuclear@61: circumvention of technological measures to the extent such circumvention nuclear@61: is effected by exercising rights under this License with respect to nuclear@61: the covered work, and you disclaim any intention to limit operation or nuclear@61: modification of the work as a means of enforcing, against the work's nuclear@61: users, your or third parties' legal rights to forbid circumvention of nuclear@61: technological measures. nuclear@61: nuclear@61: 4. Conveying Verbatim Copies. nuclear@61: nuclear@61: You may convey verbatim copies of the Program's source code as you nuclear@61: receive it, in any medium, provided that you conspicuously and nuclear@61: appropriately publish on each copy an appropriate copyright notice; nuclear@61: keep intact all notices stating that this License and any nuclear@61: non-permissive terms added in accord with section 7 apply to the code; nuclear@61: keep intact all notices of the absence of any warranty; and give all nuclear@61: recipients a copy of this License along with the Program. nuclear@61: nuclear@61: You may charge any price or no price for each copy that you convey, nuclear@61: and you may offer support or warranty protection for a fee. nuclear@61: nuclear@61: 5. Conveying Modified Source Versions. nuclear@61: nuclear@61: You may convey a work based on the Program, or the modifications to nuclear@61: produce it from the Program, in the form of source code under the nuclear@61: terms of section 4, provided that you also meet all of these conditions: nuclear@61: nuclear@61: a) The work must carry prominent notices stating that you modified nuclear@61: it, and giving a relevant date. nuclear@61: nuclear@61: b) The work must carry prominent notices stating that it is nuclear@61: released under this License and any conditions added under section nuclear@61: 7. This requirement modifies the requirement in section 4 to nuclear@61: "keep intact all notices". nuclear@61: nuclear@61: c) You must license the entire work, as a whole, under this nuclear@61: License to anyone who comes into possession of a copy. This nuclear@61: License will therefore apply, along with any applicable section 7 nuclear@61: additional terms, to the whole of the work, and all its parts, nuclear@61: regardless of how they are packaged. This License gives no nuclear@61: permission to license the work in any other way, but it does not nuclear@61: invalidate such permission if you have separately received it. nuclear@61: nuclear@61: d) If the work has interactive user interfaces, each must display nuclear@61: Appropriate Legal Notices; however, if the Program has interactive nuclear@61: interfaces that do not display Appropriate Legal Notices, your nuclear@61: work need not make them do so. nuclear@61: nuclear@61: A compilation of a covered work with other separate and independent nuclear@61: works, which are not by their nature extensions of the covered work, nuclear@61: and which are not combined with it such as to form a larger program, nuclear@61: in or on a volume of a storage or distribution medium, is called an nuclear@61: "aggregate" if the compilation and its resulting copyright are not nuclear@61: used to limit the access or legal rights of the compilation's users nuclear@61: beyond what the individual works permit. Inclusion of a covered work nuclear@61: in an aggregate does not cause this License to apply to the other nuclear@61: parts of the aggregate. nuclear@61: nuclear@61: 6. Conveying Non-Source Forms. nuclear@61: nuclear@61: You may convey a covered work in object code form under the terms nuclear@61: of sections 4 and 5, provided that you also convey the nuclear@61: machine-readable Corresponding Source under the terms of this License, nuclear@61: in one of these ways: nuclear@61: nuclear@61: a) Convey the object code in, or embodied in, a physical product nuclear@61: (including a physical distribution medium), accompanied by the nuclear@61: Corresponding Source fixed on a durable physical medium nuclear@61: customarily used for software interchange. nuclear@61: nuclear@61: b) Convey the object code in, or embodied in, a physical product nuclear@61: (including a physical distribution medium), accompanied by a nuclear@61: written offer, valid for at least three years and valid for as nuclear@61: long as you offer spare parts or customer support for that product nuclear@61: model, to give anyone who possesses the object code either (1) a nuclear@61: copy of the Corresponding Source for all the software in the nuclear@61: product that is covered by this License, on a durable physical nuclear@61: medium customarily used for software interchange, for a price no nuclear@61: more than your reasonable cost of physically performing this nuclear@61: conveying of source, or (2) access to copy the nuclear@61: Corresponding Source from a network server at no charge. nuclear@61: nuclear@61: c) Convey individual copies of the object code with a copy of the nuclear@61: written offer to provide the Corresponding Source. This nuclear@61: alternative is allowed only occasionally and noncommercially, and nuclear@61: only if you received the object code with such an offer, in accord nuclear@61: with subsection 6b. nuclear@61: nuclear@61: d) Convey the object code by offering access from a designated nuclear@61: place (gratis or for a charge), and offer equivalent access to the nuclear@61: Corresponding Source in the same way through the same place at no nuclear@61: further charge. You need not require recipients to copy the nuclear@61: Corresponding Source along with the object code. If the place to nuclear@61: copy the object code is a network server, the Corresponding Source nuclear@61: may be on a different server (operated by you or a third party) nuclear@61: that supports equivalent copying facilities, provided you maintain nuclear@61: clear directions next to the object code saying where to find the nuclear@61: Corresponding Source. Regardless of what server hosts the nuclear@61: Corresponding Source, you remain obligated to ensure that it is nuclear@61: available for as long as needed to satisfy these requirements. nuclear@61: nuclear@61: e) Convey the object code using peer-to-peer transmission, provided nuclear@61: you inform other peers where the object code and Corresponding nuclear@61: Source of the work are being offered to the general public at no nuclear@61: charge under subsection 6d. nuclear@61: nuclear@61: A separable portion of the object code, whose source code is excluded nuclear@61: from the Corresponding Source as a System Library, need not be nuclear@61: included in conveying the object code work. nuclear@61: nuclear@61: A "User Product" is either (1) a "consumer product", which means any nuclear@61: tangible personal property which is normally used for personal, family, nuclear@61: or household purposes, or (2) anything designed or sold for incorporation nuclear@61: into a dwelling. In determining whether a product is a consumer product, nuclear@61: doubtful cases shall be resolved in favor of coverage. For a particular nuclear@61: product received by a particular user, "normally used" refers to a nuclear@61: typical or common use of that class of product, regardless of the status nuclear@61: of the particular user or of the way in which the particular user nuclear@61: actually uses, or expects or is expected to use, the product. A product nuclear@61: is a consumer product regardless of whether the product has substantial nuclear@61: commercial, industrial or non-consumer uses, unless such uses represent nuclear@61: the only significant mode of use of the product. nuclear@61: nuclear@61: "Installation Information" for a User Product means any methods, nuclear@61: procedures, authorization keys, or other information required to install nuclear@61: and execute modified versions of a covered work in that User Product from nuclear@61: a modified version of its Corresponding Source. The information must nuclear@61: suffice to ensure that the continued functioning of the modified object nuclear@61: code is in no case prevented or interfered with solely because nuclear@61: modification has been made. nuclear@61: nuclear@61: If you convey an object code work under this section in, or with, or nuclear@61: specifically for use in, a User Product, and the conveying occurs as nuclear@61: part of a transaction in which the right of possession and use of the nuclear@61: User Product is transferred to the recipient in perpetuity or for a nuclear@61: fixed term (regardless of how the transaction is characterized), the nuclear@61: Corresponding Source conveyed under this section must be accompanied nuclear@61: by the Installation Information. But this requirement does not apply nuclear@61: if neither you nor any third party retains the ability to install nuclear@61: modified object code on the User Product (for example, the work has nuclear@61: been installed in ROM). nuclear@61: nuclear@61: The requirement to provide Installation Information does not include a nuclear@61: requirement to continue to provide support service, warranty, or updates nuclear@61: for a work that has been modified or installed by the recipient, or for nuclear@61: the User Product in which it has been modified or installed. Access to a nuclear@61: network may be denied when the modification itself materially and nuclear@61: adversely affects the operation of the network or violates the rules and nuclear@61: protocols for communication across the network. nuclear@61: nuclear@61: Corresponding Source conveyed, and Installation Information provided, nuclear@61: in accord with this section must be in a format that is publicly nuclear@61: documented (and with an implementation available to the public in nuclear@61: source code form), and must require no special password or key for nuclear@61: unpacking, reading or copying. nuclear@61: nuclear@61: 7. Additional Terms. nuclear@61: nuclear@61: "Additional permissions" are terms that supplement the terms of this nuclear@61: License by making exceptions from one or more of its conditions. nuclear@61: Additional permissions that are applicable to the entire Program shall nuclear@61: be treated as though they were included in this License, to the extent nuclear@61: that they are valid under applicable law. If additional permissions nuclear@61: apply only to part of the Program, that part may be used separately nuclear@61: under those permissions, but the entire Program remains governed by nuclear@61: this License without regard to the additional permissions. nuclear@61: nuclear@61: When you convey a copy of a covered work, you may at your option nuclear@61: remove any additional permissions from that copy, or from any part of nuclear@61: it. (Additional permissions may be written to require their own nuclear@61: removal in certain cases when you modify the work.) You may place nuclear@61: additional permissions on material, added by you to a covered work, nuclear@61: for which you have or can give appropriate copyright permission. nuclear@61: nuclear@61: Notwithstanding any other provision of this License, for material you nuclear@61: add to a covered work, you may (if authorized by the copyright holders of nuclear@61: that material) supplement the terms of this License with terms: nuclear@61: nuclear@61: a) Disclaiming warranty or limiting liability differently from the nuclear@61: terms of sections 15 and 16 of this License; or nuclear@61: nuclear@61: b) Requiring preservation of specified reasonable legal notices or nuclear@61: author attributions in that material or in the Appropriate Legal nuclear@61: Notices displayed by works containing it; or nuclear@61: nuclear@61: c) Prohibiting misrepresentation of the origin of that material, or nuclear@61: requiring that modified versions of such material be marked in nuclear@61: reasonable ways as different from the original version; or nuclear@61: nuclear@61: d) Limiting the use for publicity purposes of names of licensors or nuclear@61: authors of the material; or nuclear@61: nuclear@61: e) Declining to grant rights under trademark law for use of some nuclear@61: trade names, trademarks, or service marks; or nuclear@61: nuclear@61: f) Requiring indemnification of licensors and authors of that nuclear@61: material by anyone who conveys the material (or modified versions of nuclear@61: it) with contractual assumptions of liability to the recipient, for nuclear@61: any liability that these contractual assumptions directly impose on nuclear@61: those licensors and authors. nuclear@61: nuclear@61: All other non-permissive additional terms are considered "further nuclear@61: restrictions" within the meaning of section 10. If the Program as you nuclear@61: received it, or any part of it, contains a notice stating that it is nuclear@61: governed by this License along with a term that is a further nuclear@61: restriction, you may remove that term. If a license document contains nuclear@61: a further restriction but permits relicensing or conveying under this nuclear@61: License, you may add to a covered work material governed by the terms nuclear@61: of that license document, provided that the further restriction does nuclear@61: not survive such relicensing or conveying. nuclear@61: nuclear@61: If you add terms to a covered work in accord with this section, you nuclear@61: must place, in the relevant source files, a statement of the nuclear@61: additional terms that apply to those files, or a notice indicating nuclear@61: where to find the applicable terms. nuclear@61: nuclear@61: Additional terms, permissive or non-permissive, may be stated in the nuclear@61: form of a separately written license, or stated as exceptions; nuclear@61: the above requirements apply either way. nuclear@61: nuclear@61: 8. Termination. nuclear@61: nuclear@61: You may not propagate or modify a covered work except as expressly nuclear@61: provided under this License. Any attempt otherwise to propagate or nuclear@61: modify it is void, and will automatically terminate your rights under nuclear@61: this License (including any patent licenses granted under the third nuclear@61: paragraph of section 11). nuclear@61: nuclear@61: However, if you cease all violation of this License, then your nuclear@61: license from a particular copyright holder is reinstated (a) nuclear@61: provisionally, unless and until the copyright holder explicitly and nuclear@61: finally terminates your license, and (b) permanently, if the copyright nuclear@61: holder fails to notify you of the violation by some reasonable means nuclear@61: prior to 60 days after the cessation. nuclear@61: nuclear@61: Moreover, your license from a particular copyright holder is nuclear@61: reinstated permanently if the copyright holder notifies you of the nuclear@61: violation by some reasonable means, this is the first time you have nuclear@61: received notice of violation of this License (for any work) from that nuclear@61: copyright holder, and you cure the violation prior to 30 days after nuclear@61: your receipt of the notice. nuclear@61: nuclear@61: Termination of your rights under this section does not terminate the nuclear@61: licenses of parties who have received copies or rights from you under nuclear@61: this License. If your rights have been terminated and not permanently nuclear@61: reinstated, you do not qualify to receive new licenses for the same nuclear@61: material under section 10. nuclear@61: nuclear@61: 9. Acceptance Not Required for Having Copies. nuclear@61: nuclear@61: You are not required to accept this License in order to receive or nuclear@61: run a copy of the Program. Ancillary propagation of a covered work nuclear@61: occurring solely as a consequence of using peer-to-peer transmission nuclear@61: to receive a copy likewise does not require acceptance. However, nuclear@61: nothing other than this License grants you permission to propagate or nuclear@61: modify any covered work. These actions infringe copyright if you do nuclear@61: not accept this License. Therefore, by modifying or propagating a nuclear@61: covered work, you indicate your acceptance of this License to do so. nuclear@61: nuclear@61: 10. Automatic Licensing of Downstream Recipients. nuclear@61: nuclear@61: Each time you convey a covered work, the recipient automatically nuclear@61: receives a license from the original licensors, to run, modify and nuclear@61: propagate that work, subject to this License. You are not responsible nuclear@61: for enforcing compliance by third parties with this License. nuclear@61: nuclear@61: An "entity transaction" is a transaction transferring control of an nuclear@61: organization, or substantially all assets of one, or subdividing an nuclear@61: organization, or merging organizations. If propagation of a covered nuclear@61: work results from an entity transaction, each party to that nuclear@61: transaction who receives a copy of the work also receives whatever nuclear@61: licenses to the work the party's predecessor in interest had or could nuclear@61: give under the previous paragraph, plus a right to possession of the nuclear@61: Corresponding Source of the work from the predecessor in interest, if nuclear@61: the predecessor has it or can get it with reasonable efforts. nuclear@61: nuclear@61: You may not impose any further restrictions on the exercise of the nuclear@61: rights granted or affirmed under this License. For example, you may nuclear@61: not impose a license fee, royalty, or other charge for exercise of nuclear@61: rights granted under this License, and you may not initiate litigation nuclear@61: (including a cross-claim or counterclaim in a lawsuit) alleging that nuclear@61: any patent claim is infringed by making, using, selling, offering for nuclear@61: sale, or importing the Program or any portion of it. nuclear@61: nuclear@61: 11. Patents. nuclear@61: nuclear@61: A "contributor" is a copyright holder who authorizes use under this nuclear@61: License of the Program or a work on which the Program is based. The nuclear@61: work thus licensed is called the contributor's "contributor version". nuclear@61: nuclear@61: A contributor's "essential patent claims" are all patent claims nuclear@61: owned or controlled by the contributor, whether already acquired or nuclear@61: hereafter acquired, that would be infringed by some manner, permitted nuclear@61: by this License, of making, using, or selling its contributor version, nuclear@61: but do not include claims that would be infringed only as a nuclear@61: consequence of further modification of the contributor version. For nuclear@61: purposes of this definition, "control" includes the right to grant nuclear@61: patent sublicenses in a manner consistent with the requirements of nuclear@61: this License. nuclear@61: nuclear@61: Each contributor grants you a non-exclusive, worldwide, royalty-free nuclear@61: patent license under the contributor's essential patent claims, to nuclear@61: make, use, sell, offer for sale, import and otherwise run, modify and nuclear@61: propagate the contents of its contributor version. nuclear@61: nuclear@61: In the following three paragraphs, a "patent license" is any express nuclear@61: agreement or commitment, however denominated, not to enforce a patent nuclear@61: (such as an express permission to practice a patent or covenant not to nuclear@61: sue for patent infringement). To "grant" such a patent license to a nuclear@61: party means to make such an agreement or commitment not to enforce a nuclear@61: patent against the party. nuclear@61: nuclear@61: If you convey a covered work, knowingly relying on a patent license, nuclear@61: and the Corresponding Source of the work is not available for anyone nuclear@61: to copy, free of charge and under the terms of this License, through a nuclear@61: publicly available network server or other readily accessible means, nuclear@61: then you must either (1) cause the Corresponding Source to be so nuclear@61: available, or (2) arrange to deprive yourself of the benefit of the nuclear@61: patent license for this particular work, or (3) arrange, in a manner nuclear@61: consistent with the requirements of this License, to extend the patent nuclear@61: license to downstream recipients. "Knowingly relying" means you have nuclear@61: actual knowledge that, but for the patent license, your conveying the nuclear@61: covered work in a country, or your recipient's use of the covered work nuclear@61: in a country, would infringe one or more identifiable patents in that nuclear@61: country that you have reason to believe are valid. nuclear@61: nuclear@61: If, pursuant to or in connection with a single transaction or nuclear@61: arrangement, you convey, or propagate by procuring conveyance of, a nuclear@61: covered work, and grant a patent license to some of the parties nuclear@61: receiving the covered work authorizing them to use, propagate, modify nuclear@61: or convey a specific copy of the covered work, then the patent license nuclear@61: you grant is automatically extended to all recipients of the covered nuclear@61: work and works based on it. nuclear@61: nuclear@61: A patent license is "discriminatory" if it does not include within nuclear@61: the scope of its coverage, prohibits the exercise of, or is nuclear@61: conditioned on the non-exercise of one or more of the rights that are nuclear@61: specifically granted under this License. You may not convey a covered nuclear@61: work if you are a party to an arrangement with a third party that is nuclear@61: in the business of distributing software, under which you make payment nuclear@61: to the third party based on the extent of your activity of conveying nuclear@61: the work, and under which the third party grants, to any of the nuclear@61: parties who would receive the covered work from you, a discriminatory nuclear@61: patent license (a) in connection with copies of the covered work nuclear@61: conveyed by you (or copies made from those copies), or (b) primarily nuclear@61: for and in connection with specific products or compilations that nuclear@61: contain the covered work, unless you entered into that arrangement, nuclear@61: or that patent license was granted, prior to 28 March 2007. nuclear@61: nuclear@61: Nothing in this License shall be construed as excluding or limiting nuclear@61: any implied license or other defenses to infringement that may nuclear@61: otherwise be available to you under applicable patent law. nuclear@61: nuclear@61: 12. No Surrender of Others' Freedom. nuclear@61: nuclear@61: If conditions are imposed on you (whether by court order, agreement or nuclear@61: otherwise) that contradict the conditions of this License, they do not nuclear@61: excuse you from the conditions of this License. If you cannot convey a nuclear@61: covered work so as to satisfy simultaneously your obligations under this nuclear@61: License and any other pertinent obligations, then as a consequence you may nuclear@61: not convey it at all. For example, if you agree to terms that obligate you nuclear@61: to collect a royalty for further conveying from those to whom you convey nuclear@61: the Program, the only way you could satisfy both those terms and this nuclear@61: License would be to refrain entirely from conveying the Program. nuclear@61: nuclear@61: 13. Use with the GNU Affero General Public License. nuclear@61: nuclear@61: Notwithstanding any other provision of this License, you have nuclear@61: permission to link or combine any covered work with a work licensed nuclear@61: under version 3 of the GNU Affero General Public License into a single nuclear@61: combined work, and to convey the resulting work. The terms of this nuclear@61: License will continue to apply to the part which is the covered work, nuclear@61: but the special requirements of the GNU Affero General Public License, nuclear@61: section 13, concerning interaction through a network will apply to the nuclear@61: combination as such. nuclear@61: nuclear@61: 14. Revised Versions of this License. nuclear@61: nuclear@61: The Free Software Foundation may publish revised and/or new versions of nuclear@61: the GNU General Public License from time to time. Such new versions will nuclear@61: be similar in spirit to the present version, but may differ in detail to nuclear@61: address new problems or concerns. nuclear@61: nuclear@61: Each version is given a distinguishing version number. If the nuclear@61: Program specifies that a certain numbered version of the GNU General nuclear@61: Public License "or any later version" applies to it, you have the nuclear@61: option of following the terms and conditions either of that numbered nuclear@61: version or of any later version published by the Free Software nuclear@61: Foundation. If the Program does not specify a version number of the nuclear@61: GNU General Public License, you may choose any version ever published nuclear@61: by the Free Software Foundation. nuclear@61: nuclear@61: If the Program specifies that a proxy can decide which future nuclear@61: versions of the GNU General Public License can be used, that proxy's nuclear@61: public statement of acceptance of a version permanently authorizes you nuclear@61: to choose that version for the Program. nuclear@61: nuclear@61: Later license versions may give you additional or different nuclear@61: permissions. However, no additional obligations are imposed on any nuclear@61: author or copyright holder as a result of your choosing to follow a nuclear@61: later version. nuclear@61: nuclear@61: 15. Disclaimer of Warranty. nuclear@61: nuclear@61: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY nuclear@61: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT nuclear@61: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY nuclear@61: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, nuclear@61: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR nuclear@61: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM nuclear@61: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF nuclear@61: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. nuclear@61: nuclear@61: 16. Limitation of Liability. nuclear@61: nuclear@61: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING nuclear@61: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS nuclear@61: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY nuclear@61: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE nuclear@61: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF nuclear@61: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD nuclear@61: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), nuclear@61: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF nuclear@61: SUCH DAMAGES. nuclear@61: nuclear@61: 17. Interpretation of Sections 15 and 16. nuclear@61: nuclear@61: If the disclaimer of warranty and limitation of liability provided nuclear@61: above cannot be given local legal effect according to their terms, nuclear@61: reviewing courts shall apply local law that most closely approximates nuclear@61: an absolute waiver of all civil liability in connection with the nuclear@61: Program, unless a warranty or assumption of liability accompanies a nuclear@61: copy of the Program in return for a fee. nuclear@61: nuclear@61: END OF TERMS AND CONDITIONS nuclear@61: nuclear@61: How to Apply These Terms to Your New Programs nuclear@61: nuclear@61: If you develop a new program, and you want it to be of the greatest nuclear@61: possible use to the public, the best way to achieve this is to make it nuclear@61: free software which everyone can redistribute and change under these terms. nuclear@61: nuclear@61: To do so, attach the following notices to the program. It is safest nuclear@61: to attach them to the start of each source file to most effectively nuclear@61: state the exclusion of warranty; and each file should have at least nuclear@61: the "copyright" line and a pointer to where the full notice is found. nuclear@61: nuclear@61: nuclear@61: Copyright (C) nuclear@61: nuclear@61: This program is free software: you can redistribute it and/or modify nuclear@61: it under the terms of the GNU General Public License as published by nuclear@61: the Free Software Foundation, either version 3 of the License, or nuclear@61: (at your option) any later version. nuclear@61: nuclear@61: This program is distributed in the hope that it will be useful, nuclear@61: but WITHOUT ANY WARRANTY; without even the implied warranty of nuclear@61: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the nuclear@61: GNU General Public License for more details. nuclear@61: nuclear@61: You should have received a copy of the GNU General Public License nuclear@61: along with this program. If not, see . nuclear@61: nuclear@61: Also add information on how to contact you by electronic and paper mail. nuclear@61: nuclear@61: If the program does terminal interaction, make it output a short nuclear@61: notice like this when it starts in an interactive mode: nuclear@61: nuclear@61: Copyright (C) nuclear@61: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. nuclear@61: This is free software, and you are welcome to redistribute it nuclear@61: under certain conditions; type `show c' for details. nuclear@61: nuclear@61: The hypothetical commands `show w' and `show c' should show the appropriate nuclear@61: parts of the General Public License. Of course, your program's commands nuclear@61: might be different; for a GUI interface, you would use an "about box". nuclear@61: nuclear@61: You should also get your employer (if you work as a programmer) or school, nuclear@61: if any, to sign a "copyright disclaimer" for the program, if necessary. nuclear@61: For more information on this, and how to apply and follow the GNU GPL, see nuclear@61: . nuclear@61: nuclear@61: The GNU General Public License does not permit incorporating your program nuclear@61: into proprietary programs. If your program is a subroutine library, you nuclear@61: may consider it more useful to permit linking proprietary applications with nuclear@61: the library. If this is what you want to do, use the GNU Lesser General nuclear@61: Public License instead of this License. But first, please read nuclear@61: .
