Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
The licenses for most software are designed to take -away your freedom to share and change it. By contrast, the GNU General -Public License is intended to guarantee your freedom to share and -change free software--to make sure the software is free for all its -users. This General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) 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 this service 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 make -restrictions that forbid anyone to deny you these rights or to ask you -to surrender the rights. These restrictions translate to certain -responsibilities for you if you distribute copies of the software, or -if you modify it.
-For example, if you distribute copies of such a -program, whether gratis or for a fee, you must give the recipients all -the rights that you have. 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.
-We protect your rights with two steps: (1) -copyright the software, and (2) offer you this license which gives you -legal permission to copy, distribute and/or modify the software.
-Also, for each author's protection and ours, we -want to make certain that everyone understands that there is no -warranty for this free software. If the software is modified by someone -else and passed on, we want its recipients to know that what they have -is not -the original, so that any problems introduced by others will not -reflect -on the original authors' reputations.
-Finally, any free program is threatened constantly -by -software patents. We wish to avoid the danger that redistributors of a -free -program will individually obtain patent licenses, in effect making the -program -proprietary. To prevent this, we have made it clear that any patent -must -be licensed for everyone's free use or not licensed at all.
-The precise terms and conditions for copying, -distribution and modification follow.
-0. This License applies to any -program or other work which contains a notice placed by the copyright -holder saying it may be distributed under the terms of this General -Public License. The "Program", below, refers to any such program or -work, and a "work based on the Program" means either the Program or any -derivative work under copyright law: that is to say, a work containing -the Program or a portion of it, either verbatim or with modifications -and/or translated into another language. (Hereinafter, translation is -included without limitation in the term "modification".) Each licensee -is addressed as "you".
-Activities other than copying, distribution and -modification are not covered by this License; they are outside its -scope. The act of running the Program is not restricted, and the output -from the Program is covered only if its contents constitute a work -based on the Program (independent of having been made by running the -Program). Whether that is true depends on what the Program does.
-1. You may copy and distribute -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 and disclaimer of warranty; -keep intact all the notices that refer to this License and to the -absence of any warranty; and give any other recipients of the Program a -copy of this License along with the Program.
-You may charge a fee for the physical act of -transferring a copy, and you may at your option offer warranty -protection in exchange for a fee.
-2. You may modify your copy or -copies of the Program or any portion of it, thus forming a work based -on the Program, and copy and distribute such modifications or work -under the terms of Section 1 above, provided that you also meet all of -these conditions:

Version 3, 29 June 2007
+ +Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed.
+ +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:
+-
-
Thus, it is not the intent of this section to claim -rights -or contest your rights to work written entirely by you; rather, the -intent -is to exercise the right to control the distribution of derivative or -collective -works based on the Program.
-In addition, mere aggregation of another work not -based on the Program with the Program (or with a work based on the -Program) on a volume of a storage or distribution medium does not bring -the other work under the scope of this License.
-3. You may copy and distribute -the Program (or a work based on it, under Section 2) in object code or -executable form under the terms of Sections 1 and 2 above provided that -you also do one of the following: -
-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:
+-
-
If distribution of executable or object code is -made by offering access to copy from a designated place, then offering -equivalent access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to -copy the source along with the object code.
-4. You may not copy, modify, -sublicense, or distribute the Program except as expressly provided -under this License. Any attempt otherwise to copy, modify, sublicense -or distribute the Program is void, and will automatically terminate -your rights under this License. However, parties who have received -copies, or rights, from -you under this License will not have their licenses terminated so long -as such parties remain in full compliance.
-5. You are not required to accept -this License, since you have not signed it. However, nothing else -grants you permission to modify or distribute the Program or its -derivative works. These actions are prohibited by law if you do not -accept this License. Therefore, by modifying or distributing the -Program (or any work based on the Program), you indicate your -acceptance of this License to do so, and all its terms and conditions -for copying, distributing or modifying the Program or works based on -it.
-6. Each time you redistribute the -Program -(or any work based on the Program), the recipient automatically -receives a -license from the original licensor to copy, distribute or modify the -Program subject to these terms and conditions. You may not impose any -further restrictions on the recipients' exercise of the rights granted -herein. You are not responsible for enforcing compliance by third -parties to this License.
-7. If, as a consequence of a -court judgment or allegation of patent infringement or for any other -reason (not limited to patent issues), 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 distribute so as to satisfy -simultaneously your obligations under this License and any other -pertinent obligations, then as a consequence you may not distribute the -Program at all. For example, if a patent license would not permit -royalty-free redistribution of the Program by all those who receive -copies directly or indirectly through you, then the only way you could -satisfy both it and this License would be to refrain entirely from -distribution of the Program.
-If any portion of this section is held invalid or -unenforceable under any particular circumstance, the balance of the -section is intended to apply and the section as a whole is intended to -apply in other circumstances.
-It is not the purpose of this section to induce you -to -infringe any patents or other property right claims or to contest -validity of any such claims; this section has the sole purpose of -protecting the integrity of the free software distribution system, -which is implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice.
-This section is intended to make thoroughly clear -what is believed to be a consequence of the rest of this License.
-8. If the distribution and/or use -of -the Program is restricted in certain countries either by patents or by -copyrighted -interfaces, the original copyright holder who places the Program under -this -License may add an explicit geographical distribution limitation -excluding -those countries, so that distribution is permitted only in or among -countries -not thus excluded. In such case, this License incorporates the -limitation -as if written in the body of this License.
-9. The Free Software Foundation -may publish revised and/or new versions of the 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 a version number of this License which -applies to it and "any later version", you have the option of following -the terms and conditions either of that version or of any later version -published by the Free Software Foundation. If the Program does not -specify a version number of this License, you may choose any version -ever published by -the Free Software Foundation.
-10. If you wish to incorporate -parts of the Program into other free programs whose distribution -conditions are different, write to the author to ask for permission. -For software which is copyrighted by the Free Software Foundation, -write to the Free Software Foundation; we sometimes make exceptions for -this. Our decision will be guided by the two goals of preserving the -free status of all -derivatives of our free software and of promoting the sharing and reuse -of software generally.
-NO WARRANTY
-11. BECAUSE THE PROGRAM IS -LICENSED FREE OF CHARGE, 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.
-12. IN NO EVENT UNLESS REQUIRED -BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR -ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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.
--
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.
