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