Version 3, 29 June 2007

- Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed.
- -The GNU General Public License is a free, copyleft license for - software and other kinds of works.
- -The licenses for most software and other practical works are designed - to take away your freedom to share and change the works. By contrast, - the GNU General Public License is 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. We, the Free Software Foundation, use the - GNU General Public License for most of our software; it applies also to - any other work released this way by its authors. You can apply it to - your programs, too.
- -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.
- -To protect your rights, we need to prevent others from denying you - these rights or asking you to surrender the rights. Therefore, you have - certain responsibilities if you distribute copies of the software, or if - you modify it: responsibilities to respect the freedom of others.
- -For example, if you distribute copies of such a program, whether - gratis or for a fee, you must pass on to the recipients the same - freedoms that you received. You must make sure that they, too, receive - or can get the source code. And you must show them these terms so they - know their rights.
- -Developers that use the GNU GPL protect your rights with two steps: - (1) assert copyright on the software, and (2) offer you this License - giving you legal permission to copy, distribute and/or modify it.
- -For the developers' and authors' protection, the GPL clearly explains - that there is no warranty for this free software. For both users' and - authors' sake, the GPL requires that modified versions be marked as - changed, so that their problems will not be attributed erroneously to - authors of previous versions.
- -Some devices are designed to deny users access to install or run - modified versions of the software inside them, although the manufacturer - can do so. This is fundamentally incompatible with the aim of - protecting users' freedom to change the software. The systematic - pattern of such abuse occurs in the area of products for individuals to - use, which is precisely where it is most unacceptable. Therefore, we - have designed this version of the GPL to prohibit the practice for those - products. If such problems arise substantially in other domains, we - stand ready to extend this provision to those domains in future versions - of the GPL, as needed to protect the freedom of users.
- -Finally, every program is threatened constantly by software patents. - States should not allow patents to restrict development and use of - software on general-purpose computers, but in those that do, we wish to - avoid the special danger that patents applied to a free program could - make it effectively proprietary. To prevent this, the GPL assures that - patents cannot be used to render the program non-free.
- -The precise terms and conditions for copying, distribution and - modification follow.
- -“This License” refers to version 3 of the GNU 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.
- -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.
- -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.
- -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.
- -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.
- -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 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.
- -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 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.
- -“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:
- -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.
- -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.
- -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.
- -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.
- -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.
- -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.
- -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 Affero 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 special requirements of the GNU Affero General Public License, - section 13, concerning interaction through a network will apply to the - combination as such.
- -The Free Software Foundation may publish revised and/or new versions of - the GNU 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 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 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 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.
- -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.
- -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.
- -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.

+ +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 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.
+ +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 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.
+ +“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:
+ +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.
+ +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.
+ +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.
+ +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.
+ +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.
+ +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.
+ +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 Affero 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 special requirements of the GNU Affero General Public License, + section 13, concerning interaction through a network will apply to the + combination as such.
+ +The Free Software Foundation may publish revised and/or new versions of + the GNU 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 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 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 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.
+ +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.
+ +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.
+ +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.
