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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>The precise terms and conditions for copying, distribution and -modification follow. -</p> -<a name="SEC85"></a> -<h2 class="heading"> TERMS AND CONDITIONS </h2> - -<ol> -<li> Definitions. - -<p>“This License” refers to version 3 of the GNU General Public License. -</p> -<p>“Copyright” also means copyright-like laws that apply to other kinds -of works, such as semiconductor masks. -</p> -<p>“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. -</p> -<p>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. -</p> -<p>A “covered work” means either the unmodified Program or a work based -on the Program. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Source Code. - -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>The Corresponding Source need not include anything that users can -regenerate automatically from other parts of the Corresponding Source. -</p> -<p>The Corresponding Source for a work in source code form is that same -work. -</p> -</li><li> Basic Permissions. - -<p>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. -</p> -<p>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. -</p> -<p>Conveying under any other circumstances is permitted solely under the -conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. -</p> -</li><li> Protecting Users' Legal Rights From Anti-Circumvention Law. - -<p>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. -</p> -<p>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. -</p> -</li><li> Conveying Verbatim Copies. - -<p>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. -</p> -<p>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. -</p> -</li><li> Conveying Modified Source Versions. - -<p>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: -</p> -<ol> -<li> -The work must carry prominent notices stating that you modified it, -and giving a relevant date. - -</li><li> -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”. - -</li><li> -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. - -</li><li> -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. -</li></ol> - -<p>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. -</p> -</li><li> Conveying Non-Source Forms. - -<p>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: -</p> -<ol> -<li> -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. - -</li><li> -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. - -</li><li> -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. - -</li><li> -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. - -</li><li> -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. - -</li></ol> - -<p>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. -</p> -<p>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. -</p> -<p>“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. -</p> -<p>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). -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Additional Terms. - -<p>“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. -</p> -<p>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. -</p> -<p>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: -</p> -<ol> +<p>Still, this API has two problems: +</p><ul> <li> -Disclaiming warranty or limiting liability differently from the terms -of sections 15 and 16 of this License; or - -</li><li> -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 - -</li><li> -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 - -</li><li> -Limiting the use for publicity purposes of names of licensors or -authors of the material; or - -</li><li> -Declining to grant rights under trademark law for use of some trade -names, trademarks, or service marks; or - -</li><li> -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. -</li></ol> - -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Termination. - -<p>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). -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Acceptance Not Required for Having Copies. - -<p>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. -</p> -</li><li> Automatic Licensing of Downstream Recipients. - -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Patents. - -<p>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”. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> No Surrender of Others' Freedom. - -<p>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. -</p> -</li><li> Use with the GNU Affero General Public License. - -<p>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. -</p> -</li><li> Revised Versions of this License. - -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Disclaimer of Warranty. - -<p>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 particular version of the Library -with which the Combined Work was made is also called the “Linked -Version”. -</p> -<p>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. -</p> -<p>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. -</p> -</li><li> Exception to Section 3 of the GNU GPL. - -<p>You may convey a covered work under sections 3 and 4 of this License -without being bound by section 3 of the GNU GPL. -</p> -</li><li> Conveying Modified Versions. - -<p>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: -</p> -<ol> -<li> -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 - -</li><li> -under the GNU GPL, with none of the additional permissions of -this License applicable to that copy. -</li></ol> - -</li><li> Object Code Incorporating Material from Library Header Files. - -<p>The object code form of an Application may incorporate material from -a header file that is part of the Library.

It -complements the GNU General Public License, which is a copyleft -license designed for free software. -</p> -<p>We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. -</p> -</li><li> -APPLICABILITY AND DEFINITIONS - -<p>This License applies to any manual or other work, in any medium, that -contains a notice placed by the copyright holder saying it can be -distributed under the terms of this License. Such a notice grants a -world-wide, royalty-free license, unlimited in duration, to use that -work under the conditions stated herein. The “Document”, below, -refers to any such manual or work. Any member of the public is a -licensee, and is addressed as “you”. You accept the license if you -copy, modify or distribute the work in a way requiring permission -under copyright law. -</p> -<p>A “Modified Version” of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. -</p> -<p>A “Secondary Section” is a named appendix or a front-matter section -of the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall -subject (or to related matters) and contains nothing that could fall -directly within that overall subject. (Thus, if the Document is in -part a textbook of mathematics, a Secondary Section may not explain -any mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. -</p> -<p>The “Invariant Sections” are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. If a -section does not fit the above definition of Secondary then it is not -allowed to be designated as Invariant. The Document may contain zero -Invariant Sections. If the Document does not identify any Invariant -Sections then there are none. -</p> -<p>The “Cover Texts” are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. A Front-Cover Text may -be at most 5 words, and a Back-Cover Text may be at most 25 words. -</p> -<p>A “Transparent” copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, that is suitable for revising the document -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup, or absence of markup, has been arranged to thwart -or discourage subsequent modification by readers is not Transparent. -An image format is not Transparent if used for any substantial amount -of text. A copy that is not “Transparent” is called “Opaque”. -</p> -<p>Examples of suitable formats for Transparent copies include plain -<small>ASCII</small> without markup, Texinfo input format, LaTeX input -format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available -<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>, -PostScript or <acronym>PDF</acronym> designed for human modification. Examples -of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and -<acronym>JPG</acronym>. Opaque formats include proprietary formats that can be -read and edited only by proprietary word processors, <acronym>SGML</acronym> or -<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are -not generally available, and the machine-generated <acronym>HTML</acronym>, -PostScript or <acronym>PDF</acronym> produced by some word processors for -output purposes only. -</p> -<p>The “Title Page” means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, “Title Page” means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. -</p> -<p>The “publisher” means any person or entity that distributes copies -of the Document to the public. -</p> -<p>A section “Entitled XYZ” means a named subunit of the Document whose -title either is precisely XYZ or contains XYZ in parentheses following -text that translates XYZ in another language. (Here XYZ stands for a -specific section name mentioned below, such as “Acknowledgements”, -“Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” -of such a section when you modify the Document means that it remains a -section “Entitled XYZ” according to this definition. -</p> -<p>The Document may include Warranty Disclaimers next to the notice which -states that this License applies to the Document. These Warranty -Disclaimers are considered to be included by reference in this -License, but only as regards disclaiming warranties: any other -implication that these Warranty Disclaimers may have is void and has -no effect on the meaning of this License. -</p> -</li><li> -VERBATIM COPYING - -<p>You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. -</p> -<p>You may also lend copies, under the same conditions stated above, and -you may publicly display copies. -</p> -</li><li> -COPYING IN QUANTITY - -<p>If you publish printed copies (or copies in media that commonly have -printed covers) of the Document, numbering more than 100, and the -Document's license notice requires Cover Texts, you must enclose the -copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. -</p> -<p>If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. -</p> -<p>If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a computer-network location from which the general network-using -public has access to download using public-standard network protocols -a complete Transparent copy of the Document, free of added material. -If you use the latter option, you must take reasonably prudent steps, -when you begin distribution of Opaque copies in quantity, to ensure -that this Transparent copy will remain thus accessible at the stated -location until at least one year after the last time you distribute an -Opaque copy (directly or through your agents or retailers) of that -edition to the public. -</p> -<p>It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. -</p> -</li><li> -MODIFICATIONS - -<p>You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: -</p> -<ol> -<li> -Use in the Title Page (and on the covers, if any) a title distinct -from that of the Document, and from those of previous versions -(which should, if there were any, be listed in the History section -of the Document). You may use the same title as a previous version -if the original publisher of that version gives permission. - -</li><li> -List on the Title Page, as authors, one or more persons or entities -responsible for authorship of the modifications in the Modified -Version, together with at least five of the principal authors of the -Document (all of its principal authors, if it has fewer than five), -unless they release you from this requirement. - -</li><li> -State on the Title page the name of the publisher of the -Modified Version, as the publisher. - -</li><li> -Preserve all the copyright notices of the Document. - -</li><li> -Add an appropriate copyright notice for your modifications -adjacent to the other copyright notices. - -</li><li> -Include, immediately after the copyright notices, a license notice -giving the public permission to use the Modified Version under the -terms of this License, in the form shown in the Addendum below. - -</li><li> -Preserve in that license notice the full lists of Invariant Sections -and required Cover Texts given in the Document's license notice. - -</li><li> -Include an unaltered copy of this License. - -</li><li> -Preserve the section Entitled “History”, Preserve its Title, and add -to it an item stating at least the title, year, new authors, and -publisher of the Modified Version as given on the Title Page. If -there is no section Entitled “History” in the Document, create one -stating the title, year, authors, and publisher of the Document as -given on its Title Page, then add an item describing the Modified -Version as stated in the previous sentence. - -</li><li> -Preserve the network location, if any, given in the Document for -public access to a Transparent copy of the Document, and likewise -the network locations given in the Document for previous versions -it was based on. These may be placed in the “History” section. -You may omit a network location for a work that was published at -least four years before the Document itself, or if the original -publisher of the version it refers to gives permission. - -</li><li> -For any section Entitled “Acknowledgements” or “Dedications”, Preserve -the Title of the section, and preserve in the section all the -substance and tone of each of the contributor acknowledgements and/or -dedications given therein. - -</li><li> -Preserve all the Invariant Sections of the Document, -unaltered in their text and in their titles. Section numbers -or the equivalent are not considered part of the section titles. - -</li><li> -Delete any section Entitled “Endorsements”.

To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. -</p> -<p>You may add a section Entitled “Endorsements”, provided it contains -nothing but endorsements of your Modified Version by various -parties—for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. -</p> -<p>You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. -</p> -<p>The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. -</p> -</li><li> -COMBINING DOCUMENTS - -<p>You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice, and that you preserve all their Warranty Disclaimers. -</p> -<p>The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. -</p> -<p>In the combination, you must combine any sections Entitled “History” -in the various original documents, forming one section Entitled -“History”; likewise combine any sections Entitled “Acknowledgements”, -and any sections Entitled “Dedications”. You must delete all -sections Entitled “Endorsements.” -</p> -</li><li> -COLLECTIONS OF DOCUMENTS - -<p>You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. -</p> -<p>You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. -</p> -</li><li> -AGGREGATION WITH INDEPENDENT WORKS - -<p>A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, is called an “aggregate” if the copyright -resulting from the compilation is not used to limit the legal rights -of the compilation's users beyond what the individual works permit. -When the Document is included in an aggregate, this License does not -apply to the other works in the aggregate which are not themselves -derivative works of the Document. -</p> -<p>If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one half of -the entire aggregate, the Document's Cover Texts may be placed on -covers that bracket the Document within the aggregate, or the -electronic equivalent of covers if the Document is in electronic form. -Otherwise they must appear on printed covers that bracket the whole -aggregate. -</p> -</li><li> -TRANSLATION - -<p>Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License, and all the license notices in the -Document, and any Warranty Disclaimers, provided that you also include -the original English version of this License and the original versions -of those notices and disclaimers. In case of a disagreement between -the translation and the original version of this License or a notice -or disclaimer, the original version will prevail. -</p> -<p>If a section in the Document is Entitled “Acknowledgements”, -“Dedications”, or “History”, the requirement (section 4) to Preserve -its Title (section 1) will typically require changing the actual -title. -</p> -</li><li> -TERMINATION - -<p>You may not copy, modify, sublicense, or distribute the Document -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense, or distribute it is void, and -will automatically terminate your rights under this License. -</p> -<p>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. -</p> -<p>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. -</p> -<p>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, receipt of a copy of some or all of the same material does -not give you any rights to use it. -</p> -</li><li> -FUTURE REVISIONS OF THIS LICENSE - -<p>The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation 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. See -<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>. -</p> -<p>Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License “or any later version” applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. If the Document -specifies that a proxy can decide which future versions of this -License can be used, that proxy's public statement of acceptance of a -version permanently authorizes you to choose that version for the -Document. -</p> -</li><li> -RELICENSING - -<p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any -World Wide Web server that publishes copyrightable works and also -provides prominent facilities for anybody to edit those works.
