.. _license: License ============= | s4d is released under LGPL license which is an extension of the GPL license. | See below the terms of the license. | | | | GNU GENERAL PUBLIC LICENSE | Version 3, 29 June 2007 | | Copyright (C) 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. 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 | . | | | GNU LESSER GENERAL PUBLIC LICENSE | Version 3, 29 June 2007| | | Copyright (C) 2007 Free Software Foundation, Inc. | Everyone is permitted to copy and distribute verbatim copies | of this license document, but changing it is not allowed. | | | This version of the GNU Lesser General Public License incorporates | the terms and conditions of version 3 of the GNU General Public | License, supplemented by the additional permissions listed below. | | 0. Additional Definitions. | | As used herein, "this License" refers to version 3 of the GNU Lesser | General Public License, and the "GNU GPL" refers to version 3 of the GNU | General Public License. | | "The Library" refers to a covered work governed by this License, | other than an Application or a Combined Work as defined below. | | An "Application" is any work that makes use of an interface provided | by the Library, but which is not otherwise based on the Library. | Defining a subclass of a class defined by the Library is deemed a mode | of using an interface provided by the Library. | | A "Combined Work" is a work produced by combining or linking an | Application with the Library. The particular version of the Library | with which the Combined Work was made is also called the "Linked | Version". | | The "Minimal Corresponding Source" for a Combined Work means the | Corresponding Source for the Combined Work, excluding any source code | for portions of the Combined Work that, considered in isolation, are | based on the Application, and not on the Linked Version. | | The "Corresponding Application Code" for a Combined Work means the | object code and/or source code for the Application, including any data | and utility programs needed for reproducing the Combined Work from the | Application, but excluding the System Libraries of the Combined Work. | | 1. Exception to Section 3 of the GNU GPL. | | You may convey a covered work under sections 3 and 4 of this License | without being bound by section 3 of the GNU GPL. | | 2. Conveying Modified Versions. | | If you modify a copy of the Library, and, in your modifications, a | facility refers to a function or data to be supplied by an Application | that uses the facility (other than as an argument passed when the | facility is invoked), then you may convey a copy of the modified | version: | | a) under this License, provided that you make a good faith effort to | ensure that, in the event an Application does not supply the | function or data, the facility still operates, and performs | whatever part of its purpose remains meaningful, or | | b) under the GNU GPL, with none of the additional permissions of | this License applicable to that copy. | | 3. Object Code Incorporating Material from Library Header Files. | | The object code form of an Application may incorporate material from | a header file that is part of the Library. You may convey such object | code under terms of your choice, provided that, if the incorporated | material is not limited to numerical parameters, data structure | layouts and accessors, or small macros, inline functions and templates | (ten or fewer lines in length), you do both of the following: | | a) Give prominent notice with each copy of the object code that the | Library is used in it and that the Library and its use are | covered by this License. | | b) Accompany the object code with a copy of the GNU GPL and this license | document. | | 4. Combined Works. | | You may convey a Combined Work under terms of your choice that, | taken together, effectively do not restrict modification of the | portions of the Library contained in the Combined Work and reverse | engineering for debugging such modifications, if you also do each of | the following: | | a) Give prominent notice with each copy of the Combined Work that | the Library is used in it and that the Library and its use are | covered by this License. | | b) Accompany the Combined Work with a copy of the GNU GPL and this license | document. | | c) For a Combined Work that displays copyright notices during | execution, include the copyright notice for the Library among | these notices, as well as a reference directing the user to the | copies of the GNU GPL and this license document. | | d) Do one of the following: | | 0) Convey the Minimal Corresponding Source under the terms of this | License, and the Corresponding Application Code in a form | suitable for, and under terms that permit, the user to | recombine or relink the Application with a modified version of | the Linked Version to produce a modified Combined Work, in the | manner specified by section 6 of the GNU GPL for conveying | Corresponding Source. | | 1) Use a suitable shared library mechanism for linking with the | Library. A suitable mechanism is one that (a) uses at run time | a copy of the Library already present on the user's computer | system, and (b) will operate properly with a modified version | of the Library that is interface-compatible with the Linked | Version. | | e) Provide Installation Information, but only if you would otherwise | be required to provide such information under section 6 of the | GNU GPL, and only to the extent that such information is | necessary to install and execute a modified version of the | Combined Work produced by recombining or relinking the | Application with a modified version of the Linked Version. (If | you use option 4d0, the Installation Information must accompany | the Minimal Corresponding Source and Corresponding Application | Code. If you use option 4d1, you must provide the Installation | Information in the manner specified by section 6 of the GNU GPL | for conveying Corresponding Source.) | | 5. Combined Libraries. | | You may place library facilities that are a work based on the | Library side by side in a single library together with other library | facilities that are not Applications and are not covered by this | License, and convey such a combined library under terms of your | choice, if you do both of the following: | | a) Accompany the combined library with a copy of the same work based | on the Library, uncombined with any other library facilities, | conveyed under the terms of this License. | | b) Give prominent notice with the combined library that part of it | is a work based on the Library, and explaining where to find the | accompanying uncombined form of the same work. | | 6. Revised Versions of the GNU Lesser General Public License. | | The Free Software Foundation may publish revised and/or new versions | of the GNU Lesser 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 | Library as you received it specifies that a certain numbered version | of the GNU Lesser General Public License "or any later version" | applies to it, you have the option of following the terms and | conditions either of that published version or of any later version | published by the Free Software Foundation. If the Library as you | received it does not specify a version number of the GNU Lesser | General Public License, you may choose any version of the GNU Lesser | General Public License ever published by the Free Software Foundation. | | If the Library as you received it specifies that a proxy can decide | whether future versions of the GNU Lesser General Public License shall | apply, that proxy's public statement of acceptance of any version is | permanent authorization for you to choose that version for the | Library.
