b@242: GNU GENERAL PUBLIC LICENSE b@242: Version 3, 29 June 2007 b@242: b@242: Copyright (C) 2007 Free Software Foundation, Inc. b@242: Everyone is permitted to copy and distribute verbatim copies b@242: of this license document, but changing it is not allowed. b@242: b@242: Preamble b@242: b@242: The GNU General Public License is a free, copyleft license for b@242: software and other kinds of works. b@242: b@242: The licenses for most software and other practical works are designed b@242: to take away your freedom to share and change the works. By contrast, b@242: the GNU General Public License is intended to guarantee your freedom to b@242: share and change all versions of a program--to make sure it remains free b@242: software for all its users. We, the Free Software Foundation, use the b@242: GNU General Public License for most of our software; it applies also to b@242: any other work released this way by its authors. You can apply it to b@242: your programs, too. b@242: b@242: When we speak of free software, we are referring to freedom, not b@242: price. Our General Public Licenses are designed to make sure that you b@242: have the freedom to distribute copies of free software (and charge for b@242: them if you wish), that you receive source code or can get it if you b@242: want it, that you can change the software or use pieces of it in new b@242: free programs, and that you know you can do these things. b@242: b@242: To protect your rights, we need to prevent others from denying you b@242: these rights or asking you to surrender the rights. Therefore, you have b@242: certain responsibilities if you distribute copies of the software, or if b@242: you modify it: responsibilities to respect the freedom of others. b@242: b@242: For example, if you distribute copies of such a program, whether b@242: gratis or for a fee, you must pass on to the recipients the same b@242: freedoms that you received. You must make sure that they, too, receive b@242: or can get the source code. And you must show them these terms so they b@242: know their rights. b@242: b@242: Developers that use the GNU GPL protect your rights with two steps: b@242: (1) assert copyright on the software, and (2) offer you this License b@242: giving you legal permission to copy, distribute and/or modify it. b@242: b@242: For the developers' and authors' protection, the GPL clearly explains b@242: that there is no warranty for this free software. For both users' and b@242: authors' sake, the GPL requires that modified versions be marked as b@242: changed, so that their problems will not be attributed erroneously to b@242: authors of previous versions. b@242: b@242: Some devices are designed to deny users access to install or run b@242: modified versions of the software inside them, although the manufacturer b@242: can do so. This is fundamentally incompatible with the aim of b@242: protecting users' freedom to change the software. The systematic b@242: pattern of such abuse occurs in the area of products for individuals to b@242: use, which is precisely where it is most unacceptable. Therefore, we b@242: have designed this version of the GPL to prohibit the practice for those b@242: products. If such problems arise substantially in other domains, we b@242: stand ready to extend this provision to those domains in future versions b@242: of the GPL, as needed to protect the freedom of users. b@242: b@242: Finally, every program is threatened constantly by software patents. b@242: States should not allow patents to restrict development and use of b@242: software on general-purpose computers, but in those that do, we wish to b@242: avoid the special danger that patents applied to a free program could b@242: make it effectively proprietary. To prevent this, the GPL assures that b@242: patents cannot be used to render the program non-free. b@242: b@242: The precise terms and conditions for copying, distribution and b@242: modification follow. b@242: b@242: TERMS AND CONDITIONS b@242: b@242: 0. Definitions. b@242: b@242: "This License" refers to version 3 of the GNU General Public License. b@242: b@242: "Copyright" also means copyright-like laws that apply to other kinds of b@242: works, such as semiconductor masks. b@242: b@242: "The Program" refers to any copyrightable work licensed under this b@242: License. Each licensee is addressed as "you". "Licensees" and b@242: "recipients" may be individuals or organizations. b@242: b@242: To "modify" a work means to copy from or adapt all or part of the work b@242: in a fashion requiring copyright permission, other than the making of an b@242: exact copy. The resulting work is called a "modified version" of the b@242: earlier work or a work "based on" the earlier work. b@242: b@242: A "covered work" means either the unmodified Program or a work based b@242: on the Program. b@242: b@242: To "propagate" a work means to do anything with it that, without b@242: permission, would make you directly or secondarily liable for b@242: infringement under applicable copyright law, except executing it on a b@242: computer or modifying a private copy. Propagation includes copying, b@242: distribution (with or without modification), making available to the b@242: public, and in some countries other activities as well. b@242: b@242: To "convey" a work means any kind of propagation that enables other b@242: parties to make or receive copies. Mere interaction with a user through b@242: a computer network, with no transfer of a copy, is not conveying. b@242: b@242: An interactive user interface displays "Appropriate Legal Notices" b@242: to the extent that it includes a convenient and prominently visible b@242: feature that (1) displays an appropriate copyright notice, and (2) b@242: tells the user that there is no warranty for the work (except to the b@242: extent that warranties are provided), that licensees may convey the b@242: work under this License, and how to view a copy of this License. If b@242: the interface presents a list of user commands or options, such as a b@242: menu, a prominent item in the list meets this criterion. b@242: b@242: 1. Source Code. b@242: b@242: The "source code" for a work means the preferred form of the work b@242: for making modifications to it. "Object code" means any non-source b@242: form of a work. b@242: b@242: A "Standard Interface" means an interface that either is an official b@242: standard defined by a recognized standards body, or, in the case of b@242: interfaces specified for a particular programming language, one that b@242: is widely used among developers working in that language. b@242: b@242: The "System Libraries" of an executable work include anything, other b@242: than the work as a whole, that (a) is included in the normal form of b@242: packaging a Major Component, but which is not part of that Major b@242: Component, and (b) serves only to enable use of the work with that b@242: Major Component, or to implement a Standard Interface for which an b@242: implementation is available to the public in source code form. A b@242: "Major Component", in this context, means a major essential component b@242: (kernel, window system, and so on) of the specific operating system b@242: (if any) on which the executable work runs, or a compiler used to b@242: produce the work, or an object code interpreter used to run it. b@242: b@242: The "Corresponding Source" for a work in object code form means all b@242: the source code needed to generate, install, and (for an executable b@242: work) run the object code and to modify the work, including scripts to b@242: control those activities. However, it does not include the work's b@242: System Libraries, or general-purpose tools or generally available free b@242: programs which are used unmodified in performing those activities but b@242: which are not part of the work. For example, Corresponding Source b@242: includes interface definition files associated with source files for b@242: the work, and the source code for shared libraries and dynamically b@242: linked subprograms that the work is specifically designed to require, b@242: such as by intimate data communication or control flow between those b@242: subprograms and other parts of the work. b@242: b@242: The Corresponding Source need not include anything that users b@242: can regenerate automatically from other parts of the Corresponding b@242: Source. b@242: b@242: The Corresponding Source for a work in source code form is that b@242: same work. b@242: b@242: 2. Basic Permissions. b@242: b@242: All rights granted under this License are granted for the term of b@242: copyright on the Program, and are irrevocable provided the stated b@242: conditions are met. This License explicitly affirms your unlimited b@242: permission to run the unmodified Program. The output from running a b@242: covered work is covered by this License only if the output, given its b@242: content, constitutes a covered work. This License acknowledges your b@242: rights of fair use or other equivalent, as provided by copyright law. b@242: b@242: You may make, run and propagate covered works that you do not b@242: convey, without conditions so long as your license otherwise remains b@242: in force. You may convey covered works to others for the sole purpose b@242: of having them make modifications exclusively for you, or provide you b@242: with facilities for running those works, provided that you comply with b@242: the terms of this License in conveying all material for which you do b@242: not control copyright. Those thus making or running the covered works b@242: for you must do so exclusively on your behalf, under your direction b@242: and control, on terms that prohibit them from making any copies of b@242: your copyrighted material outside their relationship with you. b@242: b@242: Conveying under any other circumstances is permitted solely under b@242: the conditions stated below. Sublicensing is not allowed; section 10 b@242: makes it unnecessary. b@242: b@242: 3. Protecting Users' Legal Rights From Anti-Circumvention Law. b@242: b@242: No covered work shall be deemed part of an effective technological b@242: measure under any applicable law fulfilling obligations under article b@242: 11 of the WIPO copyright treaty adopted on 20 December 1996, or b@242: similar laws prohibiting or restricting circumvention of such b@242: measures. b@242: b@242: When you convey a covered work, you waive any legal power to forbid b@242: circumvention of technological measures to the extent such circumvention b@242: is effected by exercising rights under this License with respect to b@242: the covered work, and you disclaim any intention to limit operation or b@242: modification of the work as a means of enforcing, against the work's b@242: users, your or third parties' legal rights to forbid circumvention of b@242: technological measures. b@242: b@242: 4. Conveying Verbatim Copies. b@242: b@242: You may convey verbatim copies of the Program's source code as you b@242: receive it, in any medium, provided that you conspicuously and b@242: appropriately publish on each copy an appropriate copyright notice; b@242: keep intact all notices stating that this License and any b@242: non-permissive terms added in accord with section 7 apply to the code; b@242: keep intact all notices of the absence of any warranty; and give all b@242: recipients a copy of this License along with the Program. b@242: b@242: You may charge any price or no price for each copy that you convey, b@242: and you may offer support or warranty protection for a fee. b@242: b@242: 5. Conveying Modified Source Versions. b@242: b@242: You may convey a work based on the Program, or the modifications to b@242: produce it from the Program, in the form of source code under the b@242: terms of section 4, provided that you also meet all of these conditions: b@242: b@242: a) The work must carry prominent notices stating that you modified b@242: it, and giving a relevant date. b@242: b@242: b) The work must carry prominent notices stating that it is b@242: released under this License and any conditions added under section b@242: 7. This requirement modifies the requirement in section 4 to b@242: "keep intact all notices". b@242: b@242: c) You must license the entire work, as a whole, under this b@242: License to anyone who comes into possession of a copy. This b@242: License will therefore apply, along with any applicable section 7 b@242: additional terms, to the whole of the work, and all its parts, b@242: regardless of how they are packaged. This License gives no b@242: permission to license the work in any other way, but it does not b@242: invalidate such permission if you have separately received it. b@242: b@242: d) If the work has interactive user interfaces, each must display b@242: Appropriate Legal Notices; however, if the Program has interactive b@242: interfaces that do not display Appropriate Legal Notices, your b@242: work need not make them do so. b@242: b@242: A compilation of a covered work with other separate and independent b@242: works, which are not by their nature extensions of the covered work, b@242: and which are not combined with it such as to form a larger program, b@242: in or on a volume of a storage or distribution medium, is called an b@242: "aggregate" if the compilation and its resulting copyright are not b@242: used to limit the access or legal rights of the compilation's users b@242: beyond what the individual works permit. Inclusion of a covered work b@242: in an aggregate does not cause this License to apply to the other b@242: parts of the aggregate. b@242: b@242: 6. Conveying Non-Source Forms. b@242: b@242: You may convey a covered work in object code form under the terms b@242: of sections 4 and 5, provided that you also convey the b@242: machine-readable Corresponding Source under the terms of this License, b@242: in one of these ways: b@242: b@242: a) Convey the object code in, or embodied in, a physical product b@242: (including a physical distribution medium), accompanied by the b@242: Corresponding Source fixed on a durable physical medium b@242: customarily used for software interchange. b@242: b@242: b) Convey the object code in, or embodied in, a physical product b@242: (including a physical distribution medium), accompanied by a b@242: written offer, valid for at least three years and valid for as b@242: long as you offer spare parts or customer support for that product b@242: model, to give anyone who possesses the object code either (1) a b@242: copy of the Corresponding Source for all the software in the b@242: product that is covered by this License, on a durable physical b@242: medium customarily used for software interchange, for a price no b@242: more than your reasonable cost of physically performing this b@242: conveying of source, or (2) access to copy the b@242: Corresponding Source from a network server at no charge. b@242: b@242: c) Convey individual copies of the object code with a copy of the b@242: written offer to provide the Corresponding Source. This b@242: alternative is allowed only occasionally and noncommercially, and b@242: only if you received the object code with such an offer, in accord b@242: with subsection 6b. b@242: b@242: d) Convey the object code by offering access from a designated b@242: place (gratis or for a charge), and offer equivalent access to the b@242: Corresponding Source in the same way through the same place at no b@242: further charge. You need not require recipients to copy the b@242: Corresponding Source along with the object code. If the place to b@242: copy the object code is a network server, the Corresponding Source b@242: may be on a different server (operated by you or a third party) b@242: that supports equivalent copying facilities, provided you maintain b@242: clear directions next to the object code saying where to find the b@242: Corresponding Source. Regardless of what server hosts the b@242: Corresponding Source, you remain obligated to ensure that it is b@242: available for as long as needed to satisfy these requirements. b@242: b@242: e) Convey the object code using peer-to-peer transmission, provided b@242: you inform other peers where the object code and Corresponding b@242: Source of the work are being offered to the general public at no b@242: charge under subsection 6d. b@242: b@242: A separable portion of the object code, whose source code is excluded b@242: from the Corresponding Source as a System Library, need not be b@242: included in conveying the object code work. b@242: b@242: A "User Product" is either (1) a "consumer product", which means any b@242: tangible personal property which is normally used for personal, family, b@242: or household purposes, or (2) anything designed or sold for incorporation b@242: into a dwelling. In determining whether a product is a consumer product, b@242: doubtful cases shall be resolved in favor of coverage. For a particular b@242: product received by a particular user, "normally used" refers to a b@242: typical or common use of that class of product, regardless of the status b@242: of the particular user or of the way in which the particular user b@242: actually uses, or expects or is expected to use, the product. A product b@242: is a consumer product regardless of whether the product has substantial b@242: commercial, industrial or non-consumer uses, unless such uses represent b@242: the only significant mode of use of the product. b@242: b@242: "Installation Information" for a User Product means any methods, b@242: procedures, authorization keys, or other information required to install b@242: and execute modified versions of a covered work in that User Product from b@242: a modified version of its Corresponding Source. The information must b@242: suffice to ensure that the continued functioning of the modified object b@242: code is in no case prevented or interfered with solely because b@242: modification has been made. b@242: b@242: If you convey an object code work under this section in, or with, or b@242: specifically for use in, a User Product, and the conveying occurs as b@242: part of a transaction in which the right of possession and use of the b@242: User Product is transferred to the recipient in perpetuity or for a b@242: fixed term (regardless of how the transaction is characterized), the b@242: Corresponding Source conveyed under this section must be accompanied b@242: by the Installation Information. But this requirement does not apply b@242: if neither you nor any third party retains the ability to install b@242: modified object code on the User Product (for example, the work has b@242: been installed in ROM). b@242: b@242: The requirement to provide Installation Information does not include a b@242: requirement to continue to provide support service, warranty, or updates b@242: for a work that has been modified or installed by the recipient, or for b@242: the User Product in which it has been modified or installed. Access to a b@242: network may be denied when the modification itself materially and b@242: adversely affects the operation of the network or violates the rules and b@242: protocols for communication across the network. b@242: b@242: Corresponding Source conveyed, and Installation Information provided, b@242: in accord with this section must be in a format that is publicly b@242: documented (and with an implementation available to the public in b@242: source code form), and must require no special password or key for b@242: unpacking, reading or copying. b@242: b@242: 7. Additional Terms. b@242: b@242: "Additional permissions" are terms that supplement the terms of this b@242: License by making exceptions from one or more of its conditions. b@242: Additional permissions that are applicable to the entire Program shall b@242: be treated as though they were included in this License, to the extent b@242: that they are valid under applicable law. If additional permissions b@242: apply only to part of the Program, that part may be used separately b@242: under those permissions, but the entire Program remains governed by b@242: this License without regard to the additional permissions. b@242: b@242: When you convey a copy of a covered work, you may at your option b@242: remove any additional permissions from that copy, or from any part of b@242: it. (Additional permissions may be written to require their own b@242: removal in certain cases when you modify the work.) You may place b@242: additional permissions on material, added by you to a covered work, b@242: for which you have or can give appropriate copyright permission. b@242: b@242: Notwithstanding any other provision of this License, for material you b@242: add to a covered work, you may (if authorized by the copyright holders of b@242: that material) supplement the terms of this License with terms: b@242: b@242: a) Disclaiming warranty or limiting liability differently from the b@242: terms of sections 15 and 16 of this License; or b@242: b@242: b) Requiring preservation of specified reasonable legal notices or b@242: author attributions in that material or in the Appropriate Legal b@242: Notices displayed by works containing it; or b@242: b@242: c) Prohibiting misrepresentation of the origin of that material, or b@242: requiring that modified versions of such material be marked in b@242: reasonable ways as different from the original version; or b@242: b@242: d) Limiting the use for publicity purposes of names of licensors or b@242: authors of the material; or b@242: b@242: e) Declining to grant rights under trademark law for use of some b@242: trade names, trademarks, or service marks; or b@242: b@242: f) Requiring indemnification of licensors and authors of that b@242: material by anyone who conveys the material (or modified versions of b@242: it) with contractual assumptions of liability to the recipient, for b@242: any liability that these contractual assumptions directly impose on b@242: those licensors and authors. b@242: b@242: All other non-permissive additional terms are considered "further b@242: restrictions" within the meaning of section 10. If the Program as you b@242: received it, or any part of it, contains a notice stating that it is b@242: governed by this License along with a term that is a further b@242: restriction, you may remove that term. If a license document contains b@242: a further restriction but permits relicensing or conveying under this b@242: License, you may add to a covered work material governed by the terms b@242: of that license document, provided that the further restriction does b@242: not survive such relicensing or conveying. b@242: b@242: If you add terms to a covered work in accord with this section, you b@242: must place, in the relevant source files, a statement of the b@242: additional terms that apply to those files, or a notice indicating b@242: where to find the applicable terms. b@242: b@242: Additional terms, permissive or non-permissive, may be stated in the b@242: form of a separately written license, or stated as exceptions; b@242: the above requirements apply either way. b@242: b@242: 8. Termination. b@242: b@242: You may not propagate or modify a covered work except as expressly b@242: provided under this License. Any attempt otherwise to propagate or b@242: modify it is void, and will automatically terminate your rights under b@242: this License (including any patent licenses granted under the third b@242: paragraph of section 11). b@242: b@242: However, if you cease all violation of this License, then your b@242: license from a particular copyright holder is reinstated (a) b@242: provisionally, unless and until the copyright holder explicitly and b@242: finally terminates your license, and (b) permanently, if the copyright b@242: holder fails to notify you of the violation by some reasonable means b@242: prior to 60 days after the cessation. b@242: b@242: Moreover, your license from a particular copyright holder is b@242: reinstated permanently if the copyright holder notifies you of the b@242: violation by some reasonable means, this is the first time you have b@242: received notice of violation of this License (for any work) from that b@242: copyright holder, and you cure the violation prior to 30 days after b@242: your receipt of the notice. b@242: b@242: Termination of your rights under this section does not terminate the b@242: licenses of parties who have received copies or rights from you under b@242: this License. If your rights have been terminated and not permanently b@242: reinstated, you do not qualify to receive new licenses for the same b@242: material under section 10. b@242: b@242: 9. Acceptance Not Required for Having Copies. b@242: b@242: You are not required to accept this License in order to receive or b@242: run a copy of the Program. Ancillary propagation of a covered work b@242: occurring solely as a consequence of using peer-to-peer transmission b@242: to receive a copy likewise does not require acceptance. However, b@242: nothing other than this License grants you permission to propagate or b@242: modify any covered work. These actions infringe copyright if you do b@242: not accept this License. Therefore, by modifying or propagating a b@242: covered work, you indicate your acceptance of this License to do so. b@242: b@242: 10. Automatic Licensing of Downstream Recipients. b@242: b@242: Each time you convey a covered work, the recipient automatically b@242: receives a license from the original licensors, to run, modify and b@242: propagate that work, subject to this License. You are not responsible b@242: for enforcing compliance by third parties with this License. b@242: b@242: An "entity transaction" is a transaction transferring control of an b@242: organization, or substantially all assets of one, or subdividing an b@242: organization, or merging organizations. If propagation of a covered b@242: work results from an entity transaction, each party to that b@242: transaction who receives a copy of the work also receives whatever b@242: licenses to the work the party's predecessor in interest had or could b@242: give under the previous paragraph, plus a right to possession of the b@242: Corresponding Source of the work from the predecessor in interest, if b@242: the predecessor has it or can get it with reasonable efforts. b@242: b@242: You may not impose any further restrictions on the exercise of the b@242: rights granted or affirmed under this License. For example, you may b@242: not impose a license fee, royalty, or other charge for exercise of b@242: rights granted under this License, and you may not initiate litigation b@242: (including a cross-claim or counterclaim in a lawsuit) alleging that b@242: any patent claim is infringed by making, using, selling, offering for b@242: sale, or importing the Program or any portion of it. b@242: b@242: 11. Patents. b@242: b@242: A "contributor" is a copyright holder who authorizes use under this b@242: License of the Program or a work on which the Program is based. The b@242: work thus licensed is called the contributor's "contributor version". b@242: b@242: A contributor's "essential patent claims" are all patent claims b@242: owned or controlled by the contributor, whether already acquired or b@242: hereafter acquired, that would be infringed by some manner, permitted b@242: by this License, of making, using, or selling its contributor version, b@242: but do not include claims that would be infringed only as a b@242: consequence of further modification of the contributor version. For b@242: purposes of this definition, "control" includes the right to grant b@242: patent sublicenses in a manner consistent with the requirements of b@242: this License. b@242: b@242: Each contributor grants you a non-exclusive, worldwide, royalty-free b@242: patent license under the contributor's essential patent claims, to b@242: make, use, sell, offer for sale, import and otherwise run, modify and b@242: propagate the contents of its contributor version. b@242: b@242: In the following three paragraphs, a "patent license" is any express b@242: agreement or commitment, however denominated, not to enforce a patent b@242: (such as an express permission to practice a patent or covenant not to b@242: sue for patent infringement). To "grant" such a patent license to a b@242: party means to make such an agreement or commitment not to enforce a b@242: patent against the party. b@242: b@242: If you convey a covered work, knowingly relying on a patent license, b@242: and the Corresponding Source of the work is not available for anyone b@242: to copy, free of charge and under the terms of this License, through a b@242: publicly available network server or other readily accessible means, b@242: then you must either (1) cause the Corresponding Source to be so b@242: available, or (2) arrange to deprive yourself of the benefit of the b@242: patent license for this particular work, or (3) arrange, in a manner b@242: consistent with the requirements of this License, to extend the patent b@242: license to downstream recipients. "Knowingly relying" means you have b@242: actual knowledge that, but for the patent license, your conveying the b@242: covered work in a country, or your recipient's use of the covered work b@242: in a country, would infringe one or more identifiable patents in that b@242: country that you have reason to believe are valid. b@242: b@242: If, pursuant to or in connection with a single transaction or b@242: arrangement, you convey, or propagate by procuring conveyance of, a b@242: covered work, and grant a patent license to some of the parties b@242: receiving the covered work authorizing them to use, propagate, modify b@242: or convey a specific copy of the covered work, then the patent license b@242: you grant is automatically extended to all recipients of the covered b@242: work and works based on it. b@242: b@242: A patent license is "discriminatory" if it does not include within b@242: the scope of its coverage, prohibits the exercise of, or is b@242: conditioned on the non-exercise of one or more of the rights that are b@242: specifically granted under this License. You may not convey a covered b@242: work if you are a party to an arrangement with a third party that is b@242: in the business of distributing software, under which you make payment b@242: to the third party based on the extent of your activity of conveying b@242: the work, and under which the third party grants, to any of the b@242: parties who would receive the covered work from you, a discriminatory b@242: patent license (a) in connection with copies of the covered work b@242: conveyed by you (or copies made from those copies), or (b) primarily b@242: for and in connection with specific products or compilations that b@242: contain the covered work, unless you entered into that arrangement, b@242: or that patent license was granted, prior to 28 March 2007. b@242: b@242: Nothing in this License shall be construed as excluding or limiting b@242: any implied license or other defenses to infringement that may b@242: otherwise be available to you under applicable patent law. b@242: b@242: 12. No Surrender of Others' Freedom. b@242: b@242: If conditions are imposed on you (whether by court order, agreement or b@242: otherwise) that contradict the conditions of this License, they do not b@242: excuse you from the conditions of this License. If you cannot convey a b@242: covered work so as to satisfy simultaneously your obligations under this b@242: License and any other pertinent obligations, then as a consequence you may b@242: not convey it at all. For example, if you agree to terms that obligate you b@242: to collect a royalty for further conveying from those to whom you convey b@242: the Program, the only way you could satisfy both those terms and this b@242: License would be to refrain entirely from conveying the Program. b@242: b@242: 13. Use with the GNU Affero General Public License. b@242: b@242: Notwithstanding any other provision of this License, you have b@242: permission to link or combine any covered work with a work licensed b@242: under version 3 of the GNU Affero General Public License into a single b@242: combined work, and to convey the resulting work. The terms of this b@242: License will continue to apply to the part which is the covered work, b@242: but the special requirements of the GNU Affero General Public License, b@242: section 13, concerning interaction through a network will apply to the b@242: combination as such. b@242: b@242: 14. Revised Versions of this License. b@242: b@242: The Free Software Foundation may publish revised and/or new versions of b@242: the GNU General Public License from time to time. Such new versions will b@242: be similar in spirit to the present version, but may differ in detail to b@242: address new problems or concerns. b@242: b@242: Each version is given a distinguishing version number. If the b@242: Program specifies that a certain numbered version of the GNU General b@242: Public License "or any later version" applies to it, you have the b@242: option of following the terms and conditions either of that numbered b@242: version or of any later version published by the Free Software b@242: Foundation. If the Program does not specify a version number of the b@242: GNU General Public License, you may choose any version ever published b@242: by the Free Software Foundation. b@242: b@242: If the Program specifies that a proxy can decide which future b@242: versions of the GNU General Public License can be used, that proxy's b@242: public statement of acceptance of a version permanently authorizes you b@242: to choose that version for the Program. b@242: b@242: Later license versions may give you additional or different b@242: permissions. However, no additional obligations are imposed on any b@242: author or copyright holder as a result of your choosing to follow a b@242: later version. b@242: b@242: 15. Disclaimer of Warranty. b@242: b@242: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY b@242: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT b@242: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY b@242: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, b@242: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR b@242: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM b@242: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF b@242: ALL NECESSARY SERVICING, REPAIR OR CORRECTION. b@242: b@242: 16. Limitation of Liability. b@242: b@242: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING b@242: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS b@242: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY b@242: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE b@242: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF b@242: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD b@242: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), b@242: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF b@242: SUCH DAMAGES. b@242: b@242: 17. Interpretation of Sections 15 and 16. b@242: b@242: If the disclaimer of warranty and limitation of liability provided b@242: above cannot be given local legal effect according to their terms, b@242: reviewing courts shall apply local law that most closely approximates b@242: an absolute waiver of all civil liability in connection with the b@242: Program, unless a warranty or assumption of liability accompanies a b@242: copy of the Program in return for a fee. b@242: b@242: END OF TERMS AND CONDITIONS b@242: b@242: How to Apply These Terms to Your New Programs b@242: b@242: If you develop a new program, and you want it to be of the greatest b@242: possible use to the public, the best way to achieve this is to make it b@242: free software which everyone can redistribute and change under these terms. b@242: b@242: To do so, attach the following notices to the program. It is safest b@242: to attach them to the start of each source file to most effectively b@242: state the exclusion of warranty; and each file should have at least b@242: the "copyright" line and a pointer to where the full notice is found. b@242: b@242: b@242: Copyright (C) b@242: b@242: This program is free software: you can redistribute it and/or modify b@242: it under the terms of the GNU General Public License as published by b@242: the Free Software Foundation, either version 3 of the License, or b@242: (at your option) any later version. b@242: b@242: This program is distributed in the hope that it will be useful, b@242: but WITHOUT ANY WARRANTY; without even the implied warranty of b@242: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the b@242: GNU General Public License for more details. b@242: b@242: You should have received a copy of the GNU General Public License b@242: along with this program. If not, see . b@242: b@242: Also add information on how to contact you by electronic and paper mail. b@242: b@242: If the program does terminal interaction, make it output a short b@242: notice like this when it starts in an interactive mode: b@242: b@242: Copyright (C) b@242: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. b@242: This is free software, and you are welcome to redistribute it b@242: under certain conditions; type `show c' for details. b@242: b@242: The hypothetical commands `show w' and `show c' should show the appropriate b@242: parts of the General Public License. Of course, your program's commands b@242: might be different; for a GUI interface, you would use an "about box". b@242: b@242: You should also get your employer (if you work as a programmer) or school, b@242: if any, to sign a "copyright disclaimer" for the program, if necessary. b@242: For more information on this, and how to apply and follow the GNU GPL, see b@242: . b@242: b@242: The GNU General Public License does not permit incorporating your program b@242: into proprietary programs. If your program is a subroutine library, you b@242: may consider it more useful to permit linking proprietary applications with b@242: the library. If this is what you want to do, use the GNU Lesser General b@242: Public License instead of this License. But first, please read b@242: .
