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