torsten@473: GNU GENERAL PUBLIC LICENSE torsten@473: Version 3, 29 June 2007 torsten@473: torsten@473: Copyright (C) 2007 Free Software Foundation, Inc. torsten@473: Everyone is permitted to copy and distribute verbatim copies torsten@473: of this license document, but changing it is not allowed. torsten@473: torsten@473: Preamble torsten@473: torsten@473: The GNU General Public License is a free, copyleft license for torsten@473: software and other kinds of works. torsten@473: torsten@473: The licenses for most software and other practical works are designed torsten@473: to take away your freedom to share and change the works. By contrast, torsten@473: the GNU General Public License is intended to guarantee your freedom to torsten@473: share and change all versions of a program--to make sure it remains free torsten@473: software for all its users. We, the Free Software Foundation, use the torsten@473: GNU General Public License for most of our software; it applies also to torsten@473: any other work released this way by its authors. You can apply it to torsten@473: your programs, too. torsten@473: torsten@473: When we speak of free software, we are referring to freedom, not torsten@473: price. Our General Public Licenses are designed to make sure that you torsten@473: have the freedom to distribute copies of free software (and charge for torsten@473: them if you wish), that you receive source code or can get it if you torsten@473: want it, that you can change the software or use pieces of it in new torsten@473: free programs, and that you know you can do these things. torsten@473: torsten@473: To protect your rights, we need to prevent others from denying you torsten@473: these rights or asking you to surrender the rights. Therefore, you have torsten@473: certain responsibilities if you distribute copies of the software, or if torsten@473: you modify it: responsibilities to respect the freedom of others. torsten@473: torsten@473: For example, if you distribute copies of such a program, whether torsten@473: gratis or for a fee, you must pass on to the recipients the same torsten@473: freedoms that you received. You must make sure that they, too, receive torsten@473: or can get the source code. And you must show them these terms so they torsten@473: know their rights. torsten@473: torsten@473: Developers that use the GNU GPL protect your rights with two steps: torsten@473: (1) assert copyright on the software, and (2) offer you this License torsten@473: giving you legal permission to copy, distribute and/or modify it. torsten@473: torsten@473: For the developers' and authors' protection, the GPL clearly explains torsten@473: that there is no warranty for this free software. For both users' and torsten@473: authors' sake, the GPL requires that modified versions be marked as torsten@473: changed, so that their problems will not be attributed erroneously to torsten@473: authors of previous versions. torsten@473: torsten@473: Some devices are designed to deny users access to install or run torsten@473: modified versions of the software inside them, although the manufacturer torsten@473: can do so. This is fundamentally incompatible with the aim of torsten@473: protecting users' freedom to change the software. The systematic torsten@473: pattern of such abuse occurs in the area of products for individuals to torsten@473: use, which is precisely where it is most unacceptable. Therefore, we torsten@473: have designed this version of the GPL to prohibit the practice for those torsten@473: products. If such problems arise substantially in other domains, we torsten@473: stand ready to extend this provision to those domains in future versions torsten@473: of the GPL, as needed to protect the freedom of users. torsten@473: torsten@473: Finally, every program is threatened constantly by software patents. torsten@473: States should not allow patents to restrict development and use of torsten@473: software on general-purpose computers, but in those that do, we wish to torsten@473: avoid the special danger that patents applied to a free program could torsten@473: make it effectively proprietary. To prevent this, the GPL assures that torsten@473: patents cannot be used to render the program non-free. torsten@473: torsten@473: The precise terms and conditions for copying, distribution and torsten@473: modification follow. torsten@473: torsten@473: TERMS AND CONDITIONS torsten@473: torsten@473: 0. Definitions. torsten@473: torsten@473: "This License" refers to version 3 of the GNU General Public License. torsten@473: torsten@473: "Copyright" also means copyright-like laws that apply to other kinds of torsten@473: works, such as semiconductor masks. torsten@473: torsten@473: "The Program" refers to any copyrightable work licensed under this torsten@473: License. Each licensee is addressed as "you". "Licensees" and torsten@473: "recipients" may be individuals or organizations. torsten@473: torsten@473: To "modify" a work means to copy from or adapt all or part of the work torsten@473: in a fashion requiring copyright permission, other than the making of an torsten@473: exact copy. The resulting work is called a "modified version" of the torsten@473: earlier work or a work "based on" the earlier work. torsten@473: torsten@473: A "covered work" means either the unmodified Program or a work based torsten@473: on the Program. torsten@473: torsten@473: To "propagate" a work means to do anything with it that, without torsten@473: permission, would make you directly or secondarily liable for torsten@473: infringement under applicable copyright law, except executing it on a torsten@473: computer or modifying a private copy. Propagation includes copying, torsten@473: distribution (with or without modification), making available to the torsten@473: public, and in some countries other activities as well. torsten@473: torsten@473: To "convey" a work means any kind of propagation that enables other torsten@473: parties to make or receive copies. Mere interaction with a user through torsten@473: a computer network, with no transfer of a copy, is not conveying. torsten@473: torsten@473: An interactive user interface displays "Appropriate Legal Notices" torsten@473: to the extent that it includes a convenient and prominently visible torsten@473: feature that (1) displays an appropriate copyright notice, and (2) torsten@473: tells the user that there is no warranty for the work (except to the torsten@473: extent that warranties are provided), that licensees may convey the torsten@473: work under this License, and how to view a copy of this License. If torsten@473: the interface presents a list of user commands or options, such as a torsten@473: menu, a prominent item in the list meets this criterion. torsten@473: torsten@473: 1. Source Code. torsten@473: torsten@473: The "source code" for a work means the preferred form of the work torsten@473: for making modifications to it. "Object code" means any non-source torsten@473: form of a work. torsten@473: torsten@473: A "Standard Interface" means an interface that either is an official torsten@473: standard defined by a recognized standards body, or, in the case of torsten@473: interfaces specified for a particular programming language, one that torsten@473: is widely used among developers working in that language. torsten@473: torsten@473: The "System Libraries" of an executable work include anything, other torsten@473: than the work as a whole, that (a) is included in the normal form of torsten@473: packaging a Major Component, but which is not part of that Major torsten@473: Component, and (b) serves only to enable use of the work with that torsten@473: Major Component, or to implement a Standard Interface for which an torsten@473: implementation is available to the public in source code form. A torsten@473: "Major Component", in this context, means a major essential component torsten@473: (kernel, window system, and so on) of the specific operating system torsten@473: (if any) on which the executable work runs, or a compiler used to torsten@473: produce the work, or an object code interpreter used to run it. torsten@473: torsten@473: The "Corresponding Source" for a work in object code form means all torsten@473: the source code needed to generate, install, and (for an executable torsten@473: work) run the object code and to modify the work, including scripts to torsten@473: control those activities. However, it does not include the work's torsten@473: System Libraries, or general-purpose tools or generally available free torsten@473: programs which are used unmodified in performing those activities but torsten@473: which are not part of the work. For example, Corresponding Source torsten@473: includes interface definition files associated with source files for torsten@473: the work, and the source code for shared libraries and dynamically torsten@473: linked subprograms that the work is specifically designed to require, torsten@473: such as by intimate data communication or control flow between those torsten@473: subprograms and other parts of the work. torsten@473: torsten@473: The Corresponding Source need not include anything that users torsten@473: can regenerate automatically from other parts of the Corresponding torsten@473: Source. torsten@473: torsten@473: The Corresponding Source for a work in source code form is that torsten@473: same work. torsten@473: torsten@473: 2. Basic Permissions. torsten@473: torsten@473: All rights granted under this License are granted for the term of torsten@473: copyright on the Program, and are irrevocable provided the stated torsten@473: conditions are met. This License explicitly affirms your unlimited torsten@473: permission to run the unmodified Program. The output from running a torsten@473: covered work is covered by this License only if the output, given its torsten@473: content, constitutes a covered work. This License acknowledges your torsten@473: rights of fair use or other equivalent, as provided by copyright law. torsten@473: torsten@473: You may make, run and propagate covered works that you do not torsten@473: convey, without conditions so long as your license otherwise remains torsten@473: in force. You may convey covered works to others for the sole purpose torsten@473: of having them make modifications exclusively for you, or provide you torsten@473: with facilities for running those works, provided that you comply with torsten@473: the terms of this License in conveying all material for which you do torsten@473: not control copyright. Those thus making or running the covered works torsten@473: for you must do so exclusively on your behalf, under your direction torsten@473: and control, on terms that prohibit them from making any copies of torsten@473: your copyrighted material outside their relationship with you. torsten@473: torsten@473: Conveying under any other circumstances is permitted solely under torsten@473: the conditions stated below. Sublicensing is not allowed; section 10 torsten@473: makes it unnecessary. torsten@473: torsten@473: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. torsten@473: torsten@473: No covered work shall be deemed part of an effective technological torsten@473: measure under any applicable law fulfilling obligations under article torsten@473: 11 of the WIPO copyright treaty adopted on 20 December 1996, or torsten@473: similar laws prohibiting or restricting circumvention of such torsten@473: measures. torsten@473: torsten@473: When you convey a covered work, you waive any legal power to forbid torsten@473: circumvention of technological measures to the extent such circumvention torsten@473: is effected by exercising rights under this License with respect to torsten@473: the covered work, and you disclaim any intention to limit operation or torsten@473: modification of the work as a means of enforcing, against the work's torsten@473: users, your or third parties' legal rights to forbid circumvention of torsten@473: technological measures. torsten@473: torsten@473: 4. Conveying Verbatim Copies. torsten@473: torsten@473: You may convey verbatim copies of the Program's source code as you torsten@473: receive it, in any medium, provided that you conspicuously and torsten@473: appropriately publish on each copy an appropriate copyright notice; torsten@473: keep intact all notices stating that this License and any torsten@473: non-permissive terms added in accord with section 7 apply to the code; torsten@473: keep intact all notices of the absence of any warranty; and give all torsten@473: recipients a copy of this License along with the Program. torsten@473: torsten@473: You may charge any price or no price for each copy that you convey, torsten@473: and you may offer support or warranty protection for a fee. torsten@473: torsten@473: 5. Conveying Modified Source Versions. torsten@473: torsten@473: You may convey a work based on the Program, or the modifications to torsten@473: produce it from the Program, in the form of source code under the torsten@473: terms of section 4, provided that you also meet all of these conditions: torsten@473: torsten@473: a) The work must carry prominent notices stating that you modified torsten@473: it, and giving a relevant date. torsten@473: torsten@473: b) The work must carry prominent notices stating that it is torsten@473: released under this License and any conditions added under section torsten@473: 7. This requirement modifies the requirement in section 4 to torsten@473: "keep intact all notices". torsten@473: torsten@473: c) You must license the entire work, as a whole, under this torsten@473: License to anyone who comes into possession of a copy. This torsten@473: License will therefore apply, along with any applicable section 7 torsten@473: additional terms, to the whole of the work, and all its parts, torsten@473: regardless of how they are packaged. This License gives no torsten@473: permission to license the work in any other way, but it does not torsten@473: invalidate such permission if you have separately received it. torsten@473: torsten@473: d) If the work has interactive user interfaces, each must display torsten@473: Appropriate Legal Notices; however, if the Program has interactive torsten@473: interfaces that do not display Appropriate Legal Notices, your torsten@473: work need not make them do so. torsten@473: torsten@473: A compilation of a covered work with other separate and independent torsten@473: works, which are not by their nature extensions of the covered work, torsten@473: and which are not combined with it such as to form a larger program, torsten@473: in or on a volume of a storage or distribution medium, is called an torsten@473: "aggregate" if the compilation and its resulting copyright are not torsten@473: used to limit the access or legal rights of the compilation's users torsten@473: beyond what the individual works permit. Inclusion of a covered work torsten@473: in an aggregate does not cause this License to apply to the other torsten@473: parts of the aggregate. torsten@473: torsten@473: 6. Conveying Non-Source Forms. torsten@473: torsten@473: You may convey a covered work in object code form under the terms torsten@473: of sections 4 and 5, provided that you also convey the torsten@473: machine-readable Corresponding Source under the terms of this License, torsten@473: in one of these ways: torsten@473: torsten@473: a) Convey the object code in, or embodied in, a physical product torsten@473: (including a physical distribution medium), accompanied by the torsten@473: Corresponding Source fixed on a durable physical medium torsten@473: customarily used for software interchange. torsten@473: torsten@473: b) Convey the object code in, or embodied in, a physical product torsten@473: (including a physical distribution medium), accompanied by a torsten@473: written offer, valid for at least three years and valid for as torsten@473: long as you offer spare parts or customer support for that product torsten@473: model, to give anyone who possesses the object code either (1) a torsten@473: copy of the Corresponding Source for all the software in the torsten@473: product that is covered by this License, on a durable physical torsten@473: medium customarily used for software interchange, for a price no torsten@473: more than your reasonable cost of physically performing this torsten@473: conveying of source, or (2) access to copy the torsten@473: Corresponding Source from a network server at no charge. torsten@473: torsten@473: c) Convey individual copies of the object code with a copy of the torsten@473: written offer to provide the Corresponding Source. This torsten@473: alternative is allowed only occasionally and noncommercially, and torsten@473: only if you received the object code with such an offer, in accord torsten@473: with subsection 6b. torsten@473: torsten@473: d) Convey the object code by offering access from a designated torsten@473: place (gratis or for a charge), and offer equivalent access to the torsten@473: Corresponding Source in the same way through the same place at no torsten@473: further charge. You need not require recipients to copy the torsten@473: Corresponding Source along with the object code. If the place to torsten@473: copy the object code is a network server, the Corresponding Source torsten@473: may be on a different server (operated by you or a third party) torsten@473: that supports equivalent copying facilities, provided you maintain torsten@473: clear directions next to the object code saying where to find the torsten@473: Corresponding Source. Regardless of what server hosts the torsten@473: Corresponding Source, you remain obligated to ensure that it is torsten@473: available for as long as needed to satisfy these requirements. torsten@473: torsten@473: e) Convey the object code using peer-to-peer transmission, provided torsten@473: you inform other peers where the object code and Corresponding torsten@473: Source of the work are being offered to the general public at no torsten@473: charge under subsection 6d. torsten@473: torsten@473: A separable portion of the object code, whose source code is excluded torsten@473: from the Corresponding Source as a System Library, need not be torsten@473: included in conveying the object code work. torsten@473: torsten@473: A "User Product" is either (1) a "consumer product", which means any torsten@473: tangible personal property which is normally used for personal, family, torsten@473: or household purposes, or (2) anything designed or sold for incorporation torsten@473: into a dwelling. In determining whether a product is a consumer product, torsten@473: doubtful cases shall be resolved in favor of coverage. For a particular torsten@473: product received by a particular user, "normally used" refers to a torsten@473: typical or common use of that class of product, regardless of the status torsten@473: of the particular user or of the way in which the particular user torsten@473: actually uses, or expects or is expected to use, the product. A product torsten@473: is a consumer product regardless of whether the product has substantial torsten@473: commercial, industrial or non-consumer uses, unless such uses represent torsten@473: the only significant mode of use of the product. torsten@473: torsten@473: "Installation Information" for a User Product means any methods, torsten@473: procedures, authorization keys, or other information required to install torsten@473: and execute modified versions of a covered work in that User Product from torsten@473: a modified version of its Corresponding Source. The information must torsten@473: suffice to ensure that the continued functioning of the modified object torsten@473: code is in no case prevented or interfered with solely because torsten@473: modification has been made. torsten@473: torsten@473: If you convey an object code work under this section in, or with, or torsten@473: specifically for use in, a User Product, and the conveying occurs as torsten@473: part of a transaction in which the right of possession and use of the torsten@473: User Product is transferred to the recipient in perpetuity or for a torsten@473: fixed term (regardless of how the transaction is characterized), the torsten@473: Corresponding Source conveyed under this section must be accompanied torsten@473: by the Installation Information. But this requirement does not apply torsten@473: if neither you nor any third party retains the ability to install torsten@473: modified object code on the User Product (for example, the work has torsten@473: been installed in ROM). torsten@473: torsten@473: The requirement to provide Installation Information does not include a torsten@473: requirement to continue to provide support service, warranty, or updates torsten@473: for a work that has been modified or installed by the recipient, or for torsten@473: the User Product in which it has been modified or installed. Access to a torsten@473: network may be denied when the modification itself materially and torsten@473: adversely affects the operation of the network or violates the rules and torsten@473: protocols for communication across the network. torsten@473: torsten@473: Corresponding Source conveyed, and Installation Information provided, torsten@473: in accord with this section must be in a format that is publicly torsten@473: documented (and with an implementation available to the public in torsten@473: source code form), and must require no special password or key for torsten@473: unpacking, reading or copying. torsten@473: torsten@473: 7. Additional Terms. torsten@473: torsten@473: "Additional permissions" are terms that supplement the terms of this torsten@473: License by making exceptions from one or more of its conditions. torsten@473: Additional permissions that are applicable to the entire Program shall torsten@473: be treated as though they were included in this License, to the extent torsten@473: that they are valid under applicable law. If additional permissions torsten@473: apply only to part of the Program, that part may be used separately torsten@473: under those permissions, but the entire Program remains governed by torsten@473: this License without regard to the additional permissions. torsten@473: torsten@473: When you convey a copy of a covered work, you may at your option torsten@473: remove any additional permissions from that copy, or from any part of torsten@473: it. (Additional permissions may be written to require their own torsten@473: removal in certain cases when you modify the work.) You may place torsten@473: additional permissions on material, added by you to a covered work, torsten@473: for which you have or can give appropriate copyright permission. torsten@473: torsten@473: Notwithstanding any other provision of this License, for material you torsten@473: add to a covered work, you may (if authorized by the copyright holders of torsten@473: that material) supplement the terms of this License with terms: torsten@473: torsten@473: a) Disclaiming warranty or limiting liability differently from the torsten@473: terms of sections 15 and 16 of this License; or torsten@473: torsten@473: b) Requiring preservation of specified reasonable legal notices or torsten@473: author attributions in that material or in the Appropriate Legal torsten@473: Notices displayed by works containing it; or torsten@473: torsten@473: c) Prohibiting misrepresentation of the origin of that material, or torsten@473: requiring that modified versions of such material be marked in torsten@473: reasonable ways as different from the original version; or torsten@473: torsten@473: d) Limiting the use for publicity purposes of names of licensors or torsten@473: authors of the material; or torsten@473: torsten@473: e) Declining to grant rights under trademark law for use of some torsten@473: trade names, trademarks, or service marks; or torsten@473: torsten@473: f) Requiring indemnification of licensors and authors of that torsten@473: material by anyone who conveys the material (or modified versions of torsten@473: it) with contractual assumptions of liability to the recipient, for torsten@473: any liability that these contractual assumptions directly impose on torsten@473: those licensors and authors. torsten@473: torsten@473: All other non-permissive additional terms are considered "further torsten@473: restrictions" within the meaning of section 10. If the Program as you torsten@473: received it, or any part of it, contains a notice stating that it is torsten@473: governed by this License along with a term that is a further torsten@473: restriction, you may remove that term. If a license document contains torsten@473: a further restriction but permits relicensing or conveying under this torsten@473: License, you may add to a covered work material governed by the terms torsten@473: of that license document, provided that the further restriction does torsten@473: not survive such relicensing or conveying. torsten@473: torsten@473: If you add terms to a covered work in accord with this section, you torsten@473: must place, in the relevant source files, a statement of the torsten@473: additional terms that apply to those files, or a notice indicating torsten@473: where to find the applicable terms. torsten@473: torsten@473: Additional terms, permissive or non-permissive, may be stated in the torsten@473: form of a separately written license, or stated as exceptions; torsten@473: the above requirements apply either way. torsten@473: torsten@473: 8. Termination. torsten@473: torsten@473: You may not propagate or modify a covered work except as expressly torsten@473: provided under this License. Any attempt otherwise to propagate or torsten@473: modify it is void, and will automatically terminate your rights under torsten@473: this License (including any patent licenses granted under the third torsten@473: paragraph of section 11). torsten@473: torsten@473: However, if you cease all violation of this License, then your torsten@473: license from a particular copyright holder is reinstated (a) torsten@473: provisionally, unless and until the copyright holder explicitly and torsten@473: finally terminates your license, and (b) permanently, if the copyright torsten@473: holder fails to notify you of the violation by some reasonable means torsten@473: prior to 60 days after the cessation. torsten@473: torsten@473: Moreover, your license from a particular copyright holder is torsten@473: reinstated permanently if the copyright holder notifies you of the torsten@473: violation by some reasonable means, this is the first time you have torsten@473: received notice of violation of this License (for any work) from that torsten@473: copyright holder, and you cure the violation prior to 30 days after torsten@473: your receipt of the notice. torsten@473: torsten@473: Termination of your rights under this section does not terminate the torsten@473: licenses of parties who have received copies or rights from you under torsten@473: this License. If your rights have been terminated and not permanently torsten@473: reinstated, you do not qualify to receive new licenses for the same torsten@473: material under section 10. torsten@473: torsten@473: 9. Acceptance Not Required for Having Copies. torsten@473: torsten@473: You are not required to accept this License in order to receive or torsten@473: run a copy of the Program. Ancillary propagation of a covered work torsten@473: occurring solely as a consequence of using peer-to-peer transmission torsten@473: to receive a copy likewise does not require acceptance. However, torsten@473: nothing other than this License grants you permission to propagate or torsten@473: modify any covered work. These actions infringe copyright if you do torsten@473: not accept this License. Therefore, by modifying or propagating a torsten@473: covered work, you indicate your acceptance of this License to do so. torsten@473: torsten@473: 10. Automatic Licensing of Downstream Recipients. torsten@473: torsten@473: Each time you convey a covered work, the recipient automatically torsten@473: receives a license from the original licensors, to run, modify and torsten@473: propagate that work, subject to this License. You are not responsible torsten@473: for enforcing compliance by third parties with this License. torsten@473: torsten@473: An "entity transaction" is a transaction transferring control of an torsten@473: organization, or substantially all assets of one, or subdividing an torsten@473: organization, or merging organizations. If propagation of a covered torsten@473: work results from an entity transaction, each party to that torsten@473: transaction who receives a copy of the work also receives whatever torsten@473: licenses to the work the party's predecessor in interest had or could torsten@473: give under the previous paragraph, plus a right to possession of the torsten@473: Corresponding Source of the work from the predecessor in interest, if torsten@473: the predecessor has it or can get it with reasonable efforts. torsten@473: torsten@473: You may not impose any further restrictions on the exercise of the torsten@473: rights granted or affirmed under this License. For example, you may torsten@473: not impose a license fee, royalty, or other charge for exercise of torsten@473: rights granted under this License, and you may not initiate litigation torsten@473: (including a cross-claim or counterclaim in a lawsuit) alleging that torsten@473: any patent claim is infringed by making, using, selling, offering for torsten@473: sale, or importing the Program or any portion of it. torsten@473: torsten@473: 11. Patents. torsten@473: torsten@473: A "contributor" is a copyright holder who authorizes use under this torsten@473: License of the Program or a work on which the Program is based. The torsten@473: work thus licensed is called the contributor's "contributor version". torsten@473: torsten@473: A contributor's "essential patent claims" are all patent claims torsten@473: owned or controlled by the contributor, whether already acquired or torsten@473: hereafter acquired, that would be infringed by some manner, permitted torsten@473: by this License, of making, using, or selling its contributor version, torsten@473: but do not include claims that would be infringed only as a torsten@473: consequence of further modification of the contributor version. For torsten@473: purposes of this definition, "control" includes the right to grant torsten@473: patent sublicenses in a manner consistent with the requirements of torsten@473: this License. torsten@473: torsten@473: Each contributor grants you a non-exclusive, worldwide, royalty-free torsten@473: patent license under the contributor's essential patent claims, to torsten@473: make, use, sell, offer for sale, import and otherwise run, modify and torsten@473: propagate the contents of its contributor version. torsten@473: torsten@473: In the following three paragraphs, a "patent license" is any express torsten@473: agreement or commitment, however denominated, not to enforce a patent torsten@473: (such as an express permission to practice a patent or covenant not to torsten@473: sue for patent infringement). To "grant" such a patent license to a torsten@473: party means to make such an agreement or commitment not to enforce a torsten@473: patent against the party. torsten@473: torsten@473: If you convey a covered work, knowingly relying on a patent license, torsten@473: and the Corresponding Source of the work is not available for anyone torsten@473: to copy, free of charge and under the terms of this License, through a torsten@473: publicly available network server or other readily accessible means, torsten@473: then you must either (1) cause the Corresponding Source to be so torsten@473: available, or (2) arrange to deprive yourself of the benefit of the torsten@473: patent license for this particular work, or (3) arrange, in a manner torsten@473: consistent with the requirements of this License, to extend the patent torsten@473: license to downstream recipients. "Knowingly relying" means you have torsten@473: actual knowledge that, but for the patent license, your conveying the torsten@473: covered work in a country, or your recipient's use of the covered work torsten@473: in a country, would infringe one or more identifiable patents in that torsten@473: country that you have reason to believe are valid. torsten@473: torsten@473: If, pursuant to or in connection with a single transaction or torsten@473: arrangement, you convey, or propagate by procuring conveyance of, a torsten@473: covered work, and grant a patent license to some of the parties torsten@473: receiving the covered work authorizing them to use, propagate, modify torsten@473: or convey a specific copy of the covered work, then the patent license torsten@473: you grant is automatically extended to all recipients of the covered torsten@473: work and works based on it. torsten@473: torsten@473: A patent license is "discriminatory" if it does not include within torsten@473: the scope of its coverage, prohibits the exercise of, or is torsten@473: conditioned on the non-exercise of one or more of the rights that are torsten@473: specifically granted under this License. You may not convey a covered torsten@473: work if you are a party to an arrangement with a third party that is torsten@473: in the business of distributing software, under which you make payment torsten@473: to the third party based on the extent of your activity of conveying torsten@473: the work, and under which the third party grants, to any of the torsten@473: parties who would receive the covered work from you, a discriminatory torsten@473: patent license (a) in connection with copies of the covered work torsten@473: conveyed by you (or copies made from those copies), or (b) primarily torsten@473: for and in connection with specific products or compilations that torsten@473: contain the covered work, unless you entered into that arrangement, torsten@473: or that patent license was granted, prior to 28 March 2007. torsten@473: torsten@473: Nothing in this License shall be construed as excluding or limiting torsten@473: any implied license or other defenses to infringement that may torsten@473: otherwise be available to you under applicable patent law. torsten@473: torsten@473: 12. No Surrender of Others' Freedom. torsten@473: torsten@473: If conditions are imposed on you (whether by court order, agreement or torsten@473: otherwise) that contradict the conditions of this License, they do not torsten@473: excuse you from the conditions of this License. If you cannot convey a torsten@473: covered work so as to satisfy simultaneously your obligations under this torsten@473: License and any other pertinent obligations, then as a consequence you may torsten@473: not convey it at all. For example, if you agree to terms that obligate you torsten@473: to collect a royalty for further conveying from those to whom you convey torsten@473: the Program, the only way you could satisfy both those terms and this torsten@473: License would be to refrain entirely from conveying the Program. torsten@473: torsten@473: 13. Use with the GNU Affero General Public License. torsten@473: torsten@473: Notwithstanding any other provision of this License, you have torsten@473: permission to link or combine any covered work with a work licensed torsten@473: under version 3 of the GNU Affero General Public License into a single torsten@473: combined work, and to convey the resulting work. The terms of this torsten@473: License will continue to apply to the part which is the covered work, torsten@473: but the special requirements of the GNU Affero General Public License, torsten@473: section 13, concerning interaction through a network will apply to the torsten@473: combination as such. torsten@473: torsten@473: 14. Revised Versions of this License. torsten@473: torsten@473: The Free Software Foundation may publish revised and/or new versions of torsten@473: the GNU General Public License from time to time. Such new versions will torsten@473: be similar in spirit to the present version, but may differ in detail to torsten@473: address new problems or concerns. torsten@473: torsten@473: Each version is given a distinguishing version number. If the torsten@473: Program specifies that a certain numbered version of the GNU General torsten@473: Public License "or any later version" applies to it, you have the torsten@473: option of following the terms and conditions either of that numbered torsten@473: version or of any later version published by the Free Software torsten@473: Foundation. If the Program does not specify a version number of the torsten@473: GNU General Public License, you may choose any version ever published torsten@473: by the Free Software Foundation. torsten@473: torsten@473: If the Program specifies that a proxy can decide which future torsten@473: versions of the GNU General Public License can be used, that proxy's torsten@473: public statement of acceptance of a version permanently authorizes you torsten@473: to choose that version for the Program. torsten@473: torsten@473: Later license versions may give you additional or different torsten@473: permissions. However, no additional obligations are imposed on any torsten@473: author or copyright holder as a result of your choosing to follow a torsten@473: later version. torsten@473: torsten@473: 15. Disclaimer of Warranty. torsten@473: torsten@473: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY torsten@473: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT torsten@473: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY torsten@473: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, torsten@473: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR torsten@473: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM torsten@473: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF torsten@473: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. torsten@473: torsten@473: 16. Limitation of Liability. torsten@473: torsten@473: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING torsten@473: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS torsten@473: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY torsten@473: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE torsten@473: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF torsten@473: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD torsten@473: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), torsten@473: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF torsten@473: SUCH DAMAGES. torsten@473: torsten@473: 17. Interpretation of Sections 15 and 16. torsten@473: torsten@473: If the disclaimer of warranty and limitation of liability provided torsten@473: above cannot be given local legal effect according to their terms, torsten@473: reviewing courts shall apply local law that most closely approximates torsten@473: an absolute waiver of all civil liability in connection with the torsten@473: Program, unless a warranty or assumption of liability accompanies a torsten@473: copy of the Program in return for a fee. torsten@473: torsten@473: END OF TERMS AND CONDITIONS torsten@473: torsten@473: How to Apply These Terms to Your New Programs torsten@473: torsten@473: If you develop a new program, and you want it to be of the greatest torsten@473: possible use to the public, the best way to achieve this is to make it torsten@473: free software which everyone can redistribute and change under these terms. torsten@473: torsten@473: To do so, attach the following notices to the program. It is safest torsten@473: to attach them to the start of each source file to most effectively torsten@473: state the exclusion of warranty; and each file should have at least torsten@473: the "copyright" line and a pointer to where the full notice is found. torsten@473: torsten@473: torsten@473: Copyright (C) torsten@473: torsten@473: This program is free software: you can redistribute it and/or modify torsten@473: it under the terms of the GNU General Public License as published by torsten@473: the Free Software Foundation, either version 3 of the License, or torsten@473: (at your option) any later version. torsten@473: torsten@473: This program is distributed in the hope that it will be useful, torsten@473: but WITHOUT ANY WARRANTY; without even the implied warranty of torsten@473: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the torsten@473: GNU General Public License for more details. torsten@473: torsten@473: You should have received a copy of the GNU General Public License torsten@473: along with this program. If not, see . torsten@473: torsten@473: Also add information on how to contact you by electronic and paper mail. torsten@473: torsten@473: If the program does terminal interaction, make it output a short torsten@473: notice like this when it starts in an interactive mode: torsten@473: torsten@473: Copyright (C) torsten@473: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. torsten@473: This is free software, and you are welcome to redistribute it torsten@473: under certain conditions; type `show c' for details. torsten@473: torsten@473: The hypothetical commands `show w' and `show c' should show the appropriate torsten@473: parts of the General Public License. Of course, your program's commands torsten@473: might be different; for a GUI interface, you would use an "about box". torsten@473: torsten@473: You should also get your employer (if you work as a programmer) or school, torsten@473: if any, to sign a "copyright disclaimer" for the program, if necessary. torsten@473: For more information on this, and how to apply and follow the GNU GPL, see torsten@473: . torsten@473: torsten@473: The GNU General Public License does not permit incorporating your program torsten@473: into proprietary programs. If your program is a subroutine library, you torsten@473: may consider it more useful to permit linking proprietary applications with torsten@473: the library. If this is what you want to do, use the GNU Lesser General torsten@473: Public License instead of this License. But first, please read torsten@473: .
