teichmann@7827: GNU AFFERO GENERAL PUBLIC LICENSE teichmann@7827: Version 3, 19 November 2007 teichmann@7827: teichmann@7827: Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> teichmann@7827: Everyone is permitted to copy and distribute verbatim copies teichmann@7827: of this license document, but changing it is not allowed. teichmann@7827: teichmann@7827: Preamble teichmann@7827: teichmann@7827: The GNU Affero General Public License is a free, copyleft license for teichmann@7827: software and other kinds of works, specifically designed to ensure teichmann@7827: cooperation with the community in the case of network server software. teichmann@7827: teichmann@7827: The licenses for most software and other practical works are designed teichmann@7827: to take away your freedom to share and change the works. By contrast, teichmann@7827: our General Public Licenses are intended to guarantee your freedom to teichmann@7827: share and change all versions of a program--to make sure it remains free teichmann@7827: software for all its users. teichmann@7827: teichmann@7827: When we speak of free software, we are referring to freedom, not teichmann@7827: price. Our General Public Licenses are designed to make sure that you teichmann@7827: have the freedom to distribute copies of free software (and charge for teichmann@7827: them if you wish), that you receive source code or can get it if you teichmann@7827: want it, that you can change the software or use pieces of it in new teichmann@7827: free programs, and that you know you can do these things. teichmann@7827: teichmann@7827: Developers that use our General Public Licenses protect your rights teichmann@7827: with two steps: (1) assert copyright on the software, and (2) offer teichmann@7827: you this License which gives you legal permission to copy, distribute teichmann@7827: and/or modify the software. teichmann@7827: teichmann@7827: A secondary benefit of defending all users' freedom is that teichmann@7827: improvements made in alternate versions of the program, if they teichmann@7827: receive widespread use, become available for other developers to teichmann@7827: incorporate. Many developers of free software are heartened and teichmann@7827: encouraged by the resulting cooperation. However, in the case of teichmann@7827: software used on network servers, this result may fail to come about. teichmann@7827: The GNU General Public License permits making a modified version and teichmann@7827: letting the public access it on a server without ever releasing its teichmann@7827: source code to the public. teichmann@7827: teichmann@7827: The GNU Affero General Public License is designed specifically to teichmann@7827: ensure that, in such cases, the modified source code becomes available teichmann@7827: to the community. It requires the operator of a network server to teichmann@7827: provide the source code of the modified version running there to the teichmann@7827: users of that server. Therefore, public use of a modified version, on teichmann@7827: a publicly accessible server, gives the public access to the source teichmann@7827: code of the modified version. teichmann@7827: teichmann@7827: An older license, called the Affero General Public License and teichmann@7827: published by Affero, was designed to accomplish similar goals. This is teichmann@7827: a different license, not a version of the Affero GPL, but Affero has teichmann@7827: released a new version of the Affero GPL which permits relicensing under teichmann@7827: this license. teichmann@7827: teichmann@7827: The precise terms and conditions for copying, distribution and teichmann@7827: modification follow. teichmann@7827: teichmann@7827: TERMS AND CONDITIONS teichmann@7827: teichmann@7827: 0. Definitions. teichmann@7827: teichmann@7827: "This License" refers to version 3 of the GNU Affero General Public License. teichmann@7827: teichmann@7827: "Copyright" also means copyright-like laws that apply to other kinds of teichmann@7827: works, such as semiconductor masks. teichmann@7827: teichmann@7827: "The Program" refers to any copyrightable work licensed under this teichmann@7827: License. Each licensee is addressed as "you". "Licensees" and teichmann@7827: "recipients" may be individuals or organizations. teichmann@7827: teichmann@7827: To "modify" a work means to copy from or adapt all or part of the work teichmann@7827: in a fashion requiring copyright permission, other than the making of an teichmann@7827: exact copy. The resulting work is called a "modified version" of the teichmann@7827: earlier work or a work "based on" the earlier work. teichmann@7827: teichmann@7827: A "covered work" means either the unmodified Program or a work based teichmann@7827: on the Program. teichmann@7827: teichmann@7827: To "propagate" a work means to do anything with it that, without teichmann@7827: permission, would make you directly or secondarily liable for teichmann@7827: infringement under applicable copyright law, except executing it on a teichmann@7827: computer or modifying a private copy. Propagation includes copying, teichmann@7827: distribution (with or without modification), making available to the teichmann@7827: public, and in some countries other activities as well. teichmann@7827: teichmann@7827: To "convey" a work means any kind of propagation that enables other teichmann@7827: parties to make or receive copies. Mere interaction with a user through teichmann@7827: a computer network, with no transfer of a copy, is not conveying. teichmann@7827: teichmann@7827: An interactive user interface displays "Appropriate Legal Notices" teichmann@7827: to the extent that it includes a convenient and prominently visible teichmann@7827: feature that (1) displays an appropriate copyright notice, and (2) teichmann@7827: tells the user that there is no warranty for the work (except to the teichmann@7827: extent that warranties are provided), that licensees may convey the teichmann@7827: work under this License, and how to view a copy of this License. If teichmann@7827: the interface presents a list of user commands or options, such as a teichmann@7827: menu, a prominent item in the list meets this criterion. teichmann@7827: teichmann@7827: 1. Source Code. teichmann@7827: teichmann@7827: The "source code" for a work means the preferred form of the work teichmann@7827: for making modifications to it. "Object code" means any non-source teichmann@7827: form of a work. teichmann@7827: teichmann@7827: A "Standard Interface" means an interface that either is an official teichmann@7827: standard defined by a recognized standards body, or, in the case of teichmann@7827: interfaces specified for a particular programming language, one that teichmann@7827: is widely used among developers working in that language. teichmann@7827: teichmann@7827: The "System Libraries" of an executable work include anything, other teichmann@7827: than the work as a whole, that (a) is included in the normal form of teichmann@7827: packaging a Major Component, but which is not part of that Major teichmann@7827: Component, and (b) serves only to enable use of the work with that teichmann@7827: Major Component, or to implement a Standard Interface for which an teichmann@7827: implementation is available to the public in source code form. A teichmann@7827: "Major Component", in this context, means a major essential component teichmann@7827: (kernel, window system, and so on) of the specific operating system teichmann@7827: (if any) on which the executable work runs, or a compiler used to teichmann@7827: produce the work, or an object code interpreter used to run it. teichmann@7827: teichmann@7827: The "Corresponding Source" for a work in object code form means all teichmann@7827: the source code needed to generate, install, and (for an executable teichmann@7827: work) run the object code and to modify the work, including scripts to teichmann@7827: control those activities. However, it does not include the work's teichmann@7827: System Libraries, or general-purpose tools or generally available free teichmann@7827: programs which are used unmodified in performing those activities but teichmann@7827: which are not part of the work. For example, Corresponding Source teichmann@7827: includes interface definition files associated with source files for teichmann@7827: the work, and the source code for shared libraries and dynamically teichmann@7827: linked subprograms that the work is specifically designed to require, teichmann@7827: such as by intimate data communication or control flow between those teichmann@7827: subprograms and other parts of the work. teichmann@7827: teichmann@7827: The Corresponding Source need not include anything that users teichmann@7827: can regenerate automatically from other parts of the Corresponding teichmann@7827: Source. teichmann@7827: teichmann@7827: The Corresponding Source for a work in source code form is that teichmann@7827: same work. teichmann@7827: teichmann@7827: 2. Basic Permissions. teichmann@7827: teichmann@7827: All rights granted under this License are granted for the term of teichmann@7827: copyright on the Program, and are irrevocable provided the stated teichmann@7827: conditions are met. This License explicitly affirms your unlimited teichmann@7827: permission to run the unmodified Program. The output from running a teichmann@7827: covered work is covered by this License only if the output, given its teichmann@7827: content, constitutes a covered work. This License acknowledges your teichmann@7827: rights of fair use or other equivalent, as provided by copyright law. teichmann@7827: teichmann@7827: You may make, run and propagate covered works that you do not teichmann@7827: convey, without conditions so long as your license otherwise remains teichmann@7827: in force. You may convey covered works to others for the sole purpose teichmann@7827: of having them make modifications exclusively for you, or provide you teichmann@7827: with facilities for running those works, provided that you comply with teichmann@7827: the terms of this License in conveying all material for which you do teichmann@7827: not control copyright. Those thus making or running the covered works teichmann@7827: for you must do so exclusively on your behalf, under your direction teichmann@7827: and control, on terms that prohibit them from making any copies of teichmann@7827: your copyrighted material outside their relationship with you. teichmann@7827: teichmann@7827: Conveying under any other circumstances is permitted solely under teichmann@7827: the conditions stated below. Sublicensing is not allowed; section 10 teichmann@7827: makes it unnecessary. teichmann@7827: teichmann@7827: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. teichmann@7827: teichmann@7827: No covered work shall be deemed part of an effective technological teichmann@7827: measure under any applicable law fulfilling obligations under article teichmann@7827: 11 of the WIPO copyright treaty adopted on 20 December 1996, or teichmann@7827: similar laws prohibiting or restricting circumvention of such teichmann@7827: measures. teichmann@7827: teichmann@7827: When you convey a covered work, you waive any legal power to forbid teichmann@7827: circumvention of technological measures to the extent such circumvention teichmann@7827: is effected by exercising rights under this License with respect to teichmann@7827: the covered work, and you disclaim any intention to limit operation or teichmann@7827: modification of the work as a means of enforcing, against the work's teichmann@7827: users, your or third parties' legal rights to forbid circumvention of teichmann@7827: technological measures. teichmann@7827: teichmann@7827: 4. Conveying Verbatim Copies. teichmann@7827: teichmann@7827: You may convey verbatim copies of the Program's source code as you teichmann@7827: receive it, in any medium, provided that you conspicuously and teichmann@7827: appropriately publish on each copy an appropriate copyright notice; teichmann@7827: keep intact all notices stating that this License and any teichmann@7827: non-permissive terms added in accord with section 7 apply to the code; teichmann@7827: keep intact all notices of the absence of any warranty; and give all teichmann@7827: recipients a copy of this License along with the Program. teichmann@7827: teichmann@7827: You may charge any price or no price for each copy that you convey, teichmann@7827: and you may offer support or warranty protection for a fee. teichmann@7827: teichmann@7827: 5. Conveying Modified Source Versions. teichmann@7827: teichmann@7827: You may convey a work based on the Program, or the modifications to teichmann@7827: produce it from the Program, in the form of source code under the teichmann@7827: terms of section 4, provided that you also meet all of these conditions: teichmann@7827: teichmann@7827: a) The work must carry prominent notices stating that you modified teichmann@7827: it, and giving a relevant date. teichmann@7827: teichmann@7827: b) The work must carry prominent notices stating that it is teichmann@7827: released under this License and any conditions added under section teichmann@7827: 7. This requirement modifies the requirement in section 4 to teichmann@7827: "keep intact all notices". teichmann@7827: teichmann@7827: c) You must license the entire work, as a whole, under this teichmann@7827: License to anyone who comes into possession of a copy. This teichmann@7827: License will therefore apply, along with any applicable section 7 teichmann@7827: additional terms, to the whole of the work, and all its parts, teichmann@7827: regardless of how they are packaged. This License gives no teichmann@7827: permission to license the work in any other way, but it does not teichmann@7827: invalidate such permission if you have separately received it. teichmann@7827: teichmann@7827: d) If the work has interactive user interfaces, each must display teichmann@7827: Appropriate Legal Notices; however, if the Program has interactive teichmann@7827: interfaces that do not display Appropriate Legal Notices, your teichmann@7827: work need not make them do so. teichmann@7827: teichmann@7827: A compilation of a covered work with other separate and independent teichmann@7827: works, which are not by their nature extensions of the covered work, teichmann@7827: and which are not combined with it such as to form a larger program, teichmann@7827: in or on a volume of a storage or distribution medium, is called an teichmann@7827: "aggregate" if the compilation and its resulting copyright are not teichmann@7827: used to limit the access or legal rights of the compilation's users teichmann@7827: beyond what the individual works permit. Inclusion of a covered work teichmann@7827: in an aggregate does not cause this License to apply to the other teichmann@7827: parts of the aggregate. teichmann@7827: teichmann@7827: 6. Conveying Non-Source Forms. teichmann@7827: teichmann@7827: You may convey a covered work in object code form under the terms teichmann@7827: of sections 4 and 5, provided that you also convey the teichmann@7827: machine-readable Corresponding Source under the terms of this License, teichmann@7827: in one of these ways: teichmann@7827: teichmann@7827: a) Convey the object code in, or embodied in, a physical product teichmann@7827: (including a physical distribution medium), accompanied by the teichmann@7827: Corresponding Source fixed on a durable physical medium teichmann@7827: customarily used for software interchange. teichmann@7827: teichmann@7827: b) Convey the object code in, or embodied in, a physical product teichmann@7827: (including a physical distribution medium), accompanied by a teichmann@7827: written offer, valid for at least three years and valid for as teichmann@7827: long as you offer spare parts or customer support for that product teichmann@7827: model, to give anyone who possesses the object code either (1) a teichmann@7827: copy of the Corresponding Source for all the software in the teichmann@7827: product that is covered by this License, on a durable physical teichmann@7827: medium customarily used for software interchange, for a price no teichmann@7827: more than your reasonable cost of physically performing this teichmann@7827: conveying of source, or (2) access to copy the teichmann@7827: Corresponding Source from a network server at no charge. teichmann@7827: teichmann@7827: c) Convey individual copies of the object code with a copy of the teichmann@7827: written offer to provide the Corresponding Source. This teichmann@7827: alternative is allowed only occasionally and noncommercially, and teichmann@7827: only if you received the object code with such an offer, in accord teichmann@7827: with subsection 6b. teichmann@7827: teichmann@7827: d) Convey the object code by offering access from a designated teichmann@7827: place (gratis or for a charge), and offer equivalent access to the teichmann@7827: Corresponding Source in the same way through the same place at no teichmann@7827: further charge. You need not require recipients to copy the teichmann@7827: Corresponding Source along with the object code. If the place to teichmann@7827: copy the object code is a network server, the Corresponding Source teichmann@7827: may be on a different server (operated by you or a third party) teichmann@7827: that supports equivalent copying facilities, provided you maintain teichmann@7827: clear directions next to the object code saying where to find the teichmann@7827: Corresponding Source. Regardless of what server hosts the teichmann@7827: Corresponding Source, you remain obligated to ensure that it is teichmann@7827: available for as long as needed to satisfy these requirements. teichmann@7827: teichmann@7827: e) Convey the object code using peer-to-peer transmission, provided teichmann@7827: you inform other peers where the object code and Corresponding teichmann@7827: Source of the work are being offered to the general public at no teichmann@7827: charge under subsection 6d. teichmann@7827: teichmann@7827: A separable portion of the object code, whose source code is excluded teichmann@7827: from the Corresponding Source as a System Library, need not be teichmann@7827: included in conveying the object code work. teichmann@7827: teichmann@7827: A "User Product" is either (1) a "consumer product", which means any teichmann@7827: tangible personal property which is normally used for personal, family, teichmann@7827: or household purposes, or (2) anything designed or sold for incorporation teichmann@7827: into a dwelling. In determining whether a product is a consumer product, teichmann@7827: doubtful cases shall be resolved in favor of coverage. For a particular teichmann@7827: product received by a particular user, "normally used" refers to a teichmann@7827: typical or common use of that class of product, regardless of the status teichmann@7827: of the particular user or of the way in which the particular user teichmann@7827: actually uses, or expects or is expected to use, the product. A product teichmann@7827: is a consumer product regardless of whether the product has substantial teichmann@7827: commercial, industrial or non-consumer uses, unless such uses represent teichmann@7827: the only significant mode of use of the product. teichmann@7827: teichmann@7827: "Installation Information" for a User Product means any methods, teichmann@7827: procedures, authorization keys, or other information required to install teichmann@7827: and execute modified versions of a covered work in that User Product from teichmann@7827: a modified version of its Corresponding Source. The information must teichmann@7827: suffice to ensure that the continued functioning of the modified object teichmann@7827: code is in no case prevented or interfered with solely because teichmann@7827: modification has been made. teichmann@7827: teichmann@7827: If you convey an object code work under this section in, or with, or teichmann@7827: specifically for use in, a User Product, and the conveying occurs as teichmann@7827: part of a transaction in which the right of possession and use of the teichmann@7827: User Product is transferred to the recipient in perpetuity or for a teichmann@7827: fixed term (regardless of how the transaction is characterized), the teichmann@7827: Corresponding Source conveyed under this section must be accompanied teichmann@7827: by the Installation Information. But this requirement does not apply teichmann@7827: if neither you nor any third party retains the ability to install teichmann@7827: modified object code on the User Product (for example, the work has teichmann@7827: been installed in ROM). teichmann@7827: teichmann@7827: The requirement to provide Installation Information does not include a teichmann@7827: requirement to continue to provide support service, warranty, or updates teichmann@7827: for a work that has been modified or installed by the recipient, or for teichmann@7827: the User Product in which it has been modified or installed. Access to a teichmann@7827: network may be denied when the modification itself materially and teichmann@7827: adversely affects the operation of the network or violates the rules and teichmann@7827: protocols for communication across the network. teichmann@7827: teichmann@7827: Corresponding Source conveyed, and Installation Information provided, teichmann@7827: in accord with this section must be in a format that is publicly teichmann@7827: documented (and with an implementation available to the public in teichmann@7827: source code form), and must require no special password or key for teichmann@7827: unpacking, reading or copying. teichmann@7827: teichmann@7827: 7. Additional Terms. teichmann@7827: teichmann@7827: "Additional permissions" are terms that supplement the terms of this teichmann@7827: License by making exceptions from one or more of its conditions. teichmann@7827: Additional permissions that are applicable to the entire Program shall teichmann@7827: be treated as though they were included in this License, to the extent teichmann@7827: that they are valid under applicable law. If additional permissions teichmann@7827: apply only to part of the Program, that part may be used separately teichmann@7827: under those permissions, but the entire Program remains governed by teichmann@7827: this License without regard to the additional permissions. teichmann@7827: teichmann@7827: When you convey a copy of a covered work, you may at your option teichmann@7827: remove any additional permissions from that copy, or from any part of teichmann@7827: it. (Additional permissions may be written to require their own teichmann@7827: removal in certain cases when you modify the work.) You may place teichmann@7827: additional permissions on material, added by you to a covered work, teichmann@7827: for which you have or can give appropriate copyright permission. teichmann@7827: teichmann@7827: Notwithstanding any other provision of this License, for material you teichmann@7827: add to a covered work, you may (if authorized by the copyright holders of teichmann@7827: that material) supplement the terms of this License with terms: teichmann@7827: teichmann@7827: a) Disclaiming warranty or limiting liability differently from the teichmann@7827: terms of sections 15 and 16 of this License; or teichmann@7827: teichmann@7827: b) Requiring preservation of specified reasonable legal notices or teichmann@7827: author attributions in that material or in the Appropriate Legal teichmann@7827: Notices displayed by works containing it; or teichmann@7827: teichmann@7827: c) Prohibiting misrepresentation of the origin of that material, or teichmann@7827: requiring that modified versions of such material be marked in teichmann@7827: reasonable ways as different from the original version; or teichmann@7827: teichmann@7827: d) Limiting the use for publicity purposes of names of licensors or teichmann@7827: authors of the material; or teichmann@7827: teichmann@7827: e) Declining to grant rights under trademark law for use of some teichmann@7827: trade names, trademarks, or service marks; or teichmann@7827: teichmann@7827: f) Requiring indemnification of licensors and authors of that teichmann@7827: material by anyone who conveys the material (or modified versions of teichmann@7827: it) with contractual assumptions of liability to the recipient, for teichmann@7827: any liability that these contractual assumptions directly impose on teichmann@7827: those licensors and authors. teichmann@7827: teichmann@7827: All other non-permissive additional terms are considered "further teichmann@7827: restrictions" within the meaning of section 10. If the Program as you teichmann@7827: received it, or any part of it, contains a notice stating that it is teichmann@7827: governed by this License along with a term that is a further teichmann@7827: restriction, you may remove that term. If a license document contains teichmann@7827: a further restriction but permits relicensing or conveying under this teichmann@7827: License, you may add to a covered work material governed by the terms teichmann@7827: of that license document, provided that the further restriction does teichmann@7827: not survive such relicensing or conveying. teichmann@7827: teichmann@7827: If you add terms to a covered work in accord with this section, you teichmann@7827: must place, in the relevant source files, a statement of the teichmann@7827: additional terms that apply to those files, or a notice indicating teichmann@7827: where to find the applicable terms. teichmann@7827: teichmann@7827: Additional terms, permissive or non-permissive, may be stated in the teichmann@7827: form of a separately written license, or stated as exceptions; teichmann@7827: the above requirements apply either way. teichmann@7827: teichmann@7827: 8. Termination. teichmann@7827: teichmann@7827: You may not propagate or modify a covered work except as expressly teichmann@7827: provided under this License. Any attempt otherwise to propagate or teichmann@7827: modify it is void, and will automatically terminate your rights under teichmann@7827: this License (including any patent licenses granted under the third teichmann@7827: paragraph of section 11). teichmann@7827: teichmann@7827: However, if you cease all violation of this License, then your teichmann@7827: license from a particular copyright holder is reinstated (a) teichmann@7827: provisionally, unless and until the copyright holder explicitly and teichmann@7827: finally terminates your license, and (b) permanently, if the copyright teichmann@7827: holder fails to notify you of the violation by some reasonable means teichmann@7827: prior to 60 days after the cessation. teichmann@7827: teichmann@7827: Moreover, your license from a particular copyright holder is teichmann@7827: reinstated permanently if the copyright holder notifies you of the teichmann@7827: violation by some reasonable means, this is the first time you have teichmann@7827: received notice of violation of this License (for any work) from that teichmann@7827: copyright holder, and you cure the violation prior to 30 days after teichmann@7827: your receipt of the notice. teichmann@7827: teichmann@7827: Termination of your rights under this section does not terminate the teichmann@7827: licenses of parties who have received copies or rights from you under teichmann@7827: this License. If your rights have been terminated and not permanently teichmann@7827: reinstated, you do not qualify to receive new licenses for the same teichmann@7827: material under section 10. teichmann@7827: teichmann@7827: 9. Acceptance Not Required for Having Copies. teichmann@7827: teichmann@7827: You are not required to accept this License in order to receive or teichmann@7827: run a copy of the Program. Ancillary propagation of a covered work teichmann@7827: occurring solely as a consequence of using peer-to-peer transmission teichmann@7827: to receive a copy likewise does not require acceptance. However, teichmann@7827: nothing other than this License grants you permission to propagate or teichmann@7827: modify any covered work. These actions infringe copyright if you do teichmann@7827: not accept this License. Therefore, by modifying or propagating a teichmann@7827: covered work, you indicate your acceptance of this License to do so. teichmann@7827: teichmann@7827: 10. Automatic Licensing of Downstream Recipients. teichmann@7827: teichmann@7827: Each time you convey a covered work, the recipient automatically teichmann@7827: receives a license from the original licensors, to run, modify and teichmann@7827: propagate that work, subject to this License. You are not responsible teichmann@7827: for enforcing compliance by third parties with this License. teichmann@7827: teichmann@7827: An "entity transaction" is a transaction transferring control of an teichmann@7827: organization, or substantially all assets of one, or subdividing an teichmann@7827: organization, or merging organizations. If propagation of a covered teichmann@7827: work results from an entity transaction, each party to that teichmann@7827: transaction who receives a copy of the work also receives whatever teichmann@7827: licenses to the work the party's predecessor in interest had or could teichmann@7827: give under the previous paragraph, plus a right to possession of the teichmann@7827: Corresponding Source of the work from the predecessor in interest, if teichmann@7827: the predecessor has it or can get it with reasonable efforts. teichmann@7827: teichmann@7827: You may not impose any further restrictions on the exercise of the teichmann@7827: rights granted or affirmed under this License. For example, you may teichmann@7827: not impose a license fee, royalty, or other charge for exercise of teichmann@7827: rights granted under this License, and you may not initiate litigation teichmann@7827: (including a cross-claim or counterclaim in a lawsuit) alleging that teichmann@7827: any patent claim is infringed by making, using, selling, offering for teichmann@7827: sale, or importing the Program or any portion of it. teichmann@7827: teichmann@7827: 11. Patents. teichmann@7827: teichmann@7827: A "contributor" is a copyright holder who authorizes use under this teichmann@7827: License of the Program or a work on which the Program is based. The teichmann@7827: work thus licensed is called the contributor's "contributor version". teichmann@7827: teichmann@7827: A contributor's "essential patent claims" are all patent claims teichmann@7827: owned or controlled by the contributor, whether already acquired or teichmann@7827: hereafter acquired, that would be infringed by some manner, permitted teichmann@7827: by this License, of making, using, or selling its contributor version, teichmann@7827: but do not include claims that would be infringed only as a teichmann@7827: consequence of further modification of the contributor version. For teichmann@7827: purposes of this definition, "control" includes the right to grant teichmann@7827: patent sublicenses in a manner consistent with the requirements of teichmann@7827: this License. teichmann@7827: teichmann@7827: Each contributor grants you a non-exclusive, worldwide, royalty-free teichmann@7827: patent license under the contributor's essential patent claims, to teichmann@7827: make, use, sell, offer for sale, import and otherwise run, modify and teichmann@7827: propagate the contents of its contributor version. teichmann@7827: teichmann@7827: In the following three paragraphs, a "patent license" is any express teichmann@7827: agreement or commitment, however denominated, not to enforce a patent teichmann@7827: (such as an express permission to practice a patent or covenant not to teichmann@7827: sue for patent infringement). To "grant" such a patent license to a teichmann@7827: party means to make such an agreement or commitment not to enforce a teichmann@7827: patent against the party. teichmann@7827: teichmann@7827: If you convey a covered work, knowingly relying on a patent license, teichmann@7827: and the Corresponding Source of the work is not available for anyone teichmann@7827: to copy, free of charge and under the terms of this License, through a teichmann@7827: publicly available network server or other readily accessible means, teichmann@7827: then you must either (1) cause the Corresponding Source to be so teichmann@7827: available, or (2) arrange to deprive yourself of the benefit of the teichmann@7827: patent license for this particular work, or (3) arrange, in a manner teichmann@7827: consistent with the requirements of this License, to extend the patent teichmann@7827: license to downstream recipients. "Knowingly relying" means you have teichmann@7827: actual knowledge that, but for the patent license, your conveying the teichmann@7827: covered work in a country, or your recipient's use of the covered work teichmann@7827: in a country, would infringe one or more identifiable patents in that teichmann@7827: country that you have reason to believe are valid. teichmann@7827: teichmann@7827: If, pursuant to or in connection with a single transaction or teichmann@7827: arrangement, you convey, or propagate by procuring conveyance of, a teichmann@7827: covered work, and grant a patent license to some of the parties teichmann@7827: receiving the covered work authorizing them to use, propagate, modify teichmann@7827: or convey a specific copy of the covered work, then the patent license teichmann@7827: you grant is automatically extended to all recipients of the covered teichmann@7827: work and works based on it. teichmann@7827: teichmann@7827: A patent license is "discriminatory" if it does not include within teichmann@7827: the scope of its coverage, prohibits the exercise of, or is teichmann@7827: conditioned on the non-exercise of one or more of the rights that are teichmann@7827: specifically granted under this License. You may not convey a covered teichmann@7827: work if you are a party to an arrangement with a third party that is teichmann@7827: in the business of distributing software, under which you make payment teichmann@7827: to the third party based on the extent of your activity of conveying teichmann@7827: the work, and under which the third party grants, to any of the teichmann@7827: parties who would receive the covered work from you, a discriminatory teichmann@7827: patent license (a) in connection with copies of the covered work teichmann@7827: conveyed by you (or copies made from those copies), or (b) primarily teichmann@7827: for and in connection with specific products or compilations that teichmann@7827: contain the covered work, unless you entered into that arrangement, teichmann@7827: or that patent license was granted, prior to 28 March 2007. teichmann@7827: teichmann@7827: Nothing in this License shall be construed as excluding or limiting teichmann@7827: any implied license or other defenses to infringement that may teichmann@7827: otherwise be available to you under applicable patent law. teichmann@7827: teichmann@7827: 12. No Surrender of Others' Freedom. teichmann@7827: teichmann@7827: If conditions are imposed on you (whether by court order, agreement or teichmann@7827: otherwise) that contradict the conditions of this License, they do not teichmann@7827: excuse you from the conditions of this License. If you cannot convey a teichmann@7827: covered work so as to satisfy simultaneously your obligations under this teichmann@7827: License and any other pertinent obligations, then as a consequence you may teichmann@7827: not convey it at all. For example, if you agree to terms that obligate you teichmann@7827: to collect a royalty for further conveying from those to whom you convey teichmann@7827: the Program, the only way you could satisfy both those terms and this teichmann@7827: License would be to refrain entirely from conveying the Program. teichmann@7827: teichmann@7827: 13. Remote Network Interaction; Use with the GNU General Public License. teichmann@7827: teichmann@7827: Notwithstanding any other provision of this License, if you modify the teichmann@7827: Program, your modified version must prominently offer all users teichmann@7827: interacting with it remotely through a computer network (if your version teichmann@7827: supports such interaction) an opportunity to receive the Corresponding teichmann@7827: Source of your version by providing access to the Corresponding Source teichmann@7827: from a network server at no charge, through some standard or customary teichmann@7827: means of facilitating copying of software. This Corresponding Source teichmann@7827: shall include the Corresponding Source for any work covered by version 3 teichmann@7827: of the GNU General Public License that is incorporated pursuant to the teichmann@7827: following paragraph. teichmann@7827: teichmann@7827: Notwithstanding any other provision of this License, you have teichmann@7827: permission to link or combine any covered work with a work licensed teichmann@7827: under version 3 of the GNU General Public License into a single teichmann@7827: combined work, and to convey the resulting work. The terms of this teichmann@7827: License will continue to apply to the part which is the covered work, teichmann@7827: but the work with which it is combined will remain governed by version teichmann@7827: 3 of the GNU General Public License. teichmann@7827: teichmann@7827: 14. Revised Versions of this License. teichmann@7827: teichmann@7827: The Free Software Foundation may publish revised and/or new versions of teichmann@7827: the GNU Affero General Public License from time to time. Such new versions teichmann@7827: will be similar in spirit to the present version, but may differ in detail to teichmann@7827: address new problems or concerns. teichmann@7827: teichmann@7827: Each version is given a distinguishing version number. If the teichmann@7827: Program specifies that a certain numbered version of the GNU Affero General teichmann@7827: Public License "or any later version" applies to it, you have the teichmann@7827: option of following the terms and conditions either of that numbered teichmann@7827: version or of any later version published by the Free Software teichmann@7827: Foundation. If the Program does not specify a version number of the teichmann@7827: GNU Affero General Public License, you may choose any version ever published teichmann@7827: by the Free Software Foundation. teichmann@7827: teichmann@7827: If the Program specifies that a proxy can decide which future teichmann@7827: versions of the GNU Affero General Public License can be used, that proxy's teichmann@7827: public statement of acceptance of a version permanently authorizes you teichmann@7827: to choose that version for the Program. teichmann@7827: teichmann@7827: Later license versions may give you additional or different teichmann@7827: permissions. However, no additional obligations are imposed on any teichmann@7827: author or copyright holder as a result of your choosing to follow a teichmann@7827: later version. teichmann@7827: teichmann@7827: 15. Disclaimer of Warranty. teichmann@7827: teichmann@7827: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY teichmann@7827: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT teichmann@7827: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY teichmann@7827: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, teichmann@7827: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR teichmann@7827: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM teichmann@7827: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF teichmann@7827: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. teichmann@7827: teichmann@7827: 16. Limitation of Liability. teichmann@7827: teichmann@7827: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING teichmann@7827: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS teichmann@7827: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY teichmann@7827: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE teichmann@7827: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF teichmann@7827: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD teichmann@7827: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), teichmann@7827: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF teichmann@7827: SUCH DAMAGES. teichmann@7827: teichmann@7827: 17. Interpretation of Sections 15 and 16. teichmann@7827: teichmann@7827: If the disclaimer of warranty and limitation of liability provided teichmann@7827: above cannot be given local legal effect according to their terms, teichmann@7827: reviewing courts shall apply local law that most closely approximates teichmann@7827: an absolute waiver of all civil liability in connection with the teichmann@7827: Program, unless a warranty or assumption of liability accompanies a teichmann@7827: copy of the Program in return for a fee. teichmann@7827: teichmann@7827: END OF TERMS AND CONDITIONS teichmann@7827: teichmann@7827: How to Apply These Terms to Your New Programs teichmann@7827: teichmann@7827: If you develop a new program, and you want it to be of the greatest teichmann@7827: possible use to the public, the best way to achieve this is to make it teichmann@7827: free software which everyone can redistribute and change under these terms. teichmann@7827: teichmann@7827: To do so, attach the following notices to the program. It is safest teichmann@7827: to attach them to the start of each source file to most effectively teichmann@7827: state the exclusion of warranty; and each file should have at least teichmann@7827: the "copyright" line and a pointer to where the full notice is found. teichmann@7827: teichmann@7827: <one line to give the program's name and a brief idea of what it does.> teichmann@7827: Copyright (C) <year> <name of author> teichmann@7827: teichmann@7827: This program is free software: you can redistribute it and/or modify teichmann@7827: it under the terms of the GNU Affero General Public License as published by teichmann@7827: the Free Software Foundation, either version 3 of the License, or teichmann@7827: (at your option) any later version. teichmann@7827: teichmann@7827: This program is distributed in the hope that it will be useful, teichmann@7827: but WITHOUT ANY WARRANTY; without even the implied warranty of teichmann@7827: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the teichmann@7827: GNU Affero General Public License for more details. teichmann@7827: teichmann@7827: You should have received a copy of the GNU Affero General Public License teichmann@7827: along with this program. If not, see <http://www.gnu.org/licenses/>. teichmann@7827: teichmann@7827: Also add information on how to contact you by electronic and paper mail. teichmann@7827: teichmann@7827: If your software can interact with users remotely through a computer teichmann@7827: network, you should also make sure that it provides a way for users to teichmann@7827: get its source. For example, if your program is a web application, its teichmann@7827: interface could display a "Source" link that leads users to an archive teichmann@7827: of the code. There are many ways you could offer source, and different teichmann@7827: solutions will be better for different programs; see section 13 for the teichmann@7827: specific requirements. teichmann@7827: teichmann@7827: You should also get your employer (if you work as a programmer) or school, teichmann@7827: if any, to sign a "copyright disclaimer" for the program, if necessary. teichmann@7827: For more information on this, and how to apply and follow the GNU AGPL, see teichmann@7827: <http://www.gnu.org/licenses/>.
