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