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