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