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.

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. + +    <one line to give the program's name and a brief idea of what it does.> +    Copyright (C) <year>  <name of author> + +    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.

If not, see <http://www.gnu.org/licenses/>. + +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: + +    <program>  Copyright (C) <year>  <name of author> +    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 +<http://www.gnu.org/licenses/>. + +  The GNU General Public License does not permit incorporating your program +into proprietary programs.
