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. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. + diff --git a/LICENSE.md b/LICENSE.md deleted file mode 100644 index 1110e898..00000000 --- a/LICENSE.md +++ /dev/null @@ -1,595 +0,0 @@ -GNU General Public License -========================== - -_Version 3, 29 June 2007_ -_Copyright © 2007 Free Software Foundation, Inc. <>_ - -Everyone is permitted to copy and distribute verbatim copies of this license -document, but changing it is not allowed. - -## Preamble - -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. - -## 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.

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.

Of course, your program's commands might be different; -for a GUI interface, you would use an “about box”. - -You should also get your employer (if you work as a programmer) or school, if any, to -sign a “copyright disclaimer” for the program, if necessary. For more -information on this, and how to apply and follow the GNU GPL, see -<>. - -The GNU General Public License does not permit incorporating your program into -proprietary programs. If your program is a subroutine library, you may consider it -more useful to permit linking proprietary applications with the library. If this is -what you want to do, use the GNU Lesser General Public License instead of this -License. But first, please read -<>.
