It also counts as the successor of the GNULibrary Public License, version 2, hence the version number 2.1.]PreambleThe licenses for most software are designed to take away your freedom to share and change it.By contrast, the GNU General Public Licenses are intended to guarantee your freedom to shareand change free software – to make sure the software is free for all its users.This license, the Lesser General Public License, applies to some specially designated softwarepackages – typically libraries – of the Free Software Foundation and other authors who decideto use it. You can use it too, but we suggest you first think carefully about whether this license orthe ordinary General Public License is the better strategy to use in any particular case, based onthe explanations below.When we speak of free software, we are referring to freedom of use, not price. Our GeneralPublic Licenses are designed to make sure that you have the freedom to distribute copies of freesoftware (and charge for this service if you wish); that you receive source code or can get it if youwant it; that you can change the software and use pieces of it in new free programs; and thatyou are informed that you can do these things.To protect your rights, we need to make restrictions that forbid distributors to deny youthese rights or to ask you to surrender these rights. These restrictions translate to certainresponsibilities for you if you distribute copies of the library or if you modify it.For example, if you distribute copies of the library, whether gratis or for a fee, you must givethe recipients all the rights that we gave you. You must make sure that they, too, receive or canget the source code. If you link other code with the library, you must provide complete object filesto the recipients, so that they can relink them with the library after making changes to the libraryand recompiling it. And you must show them these terms so they know their rights.We protect your rights with a two-step method: (1) we copyright the library, and (2) we offeryou this license, which gives you legal permission to copy, distribute and/or modify the library.To protect each distributor, we want to make it very clear that there is no warranty for the freelibrary. Also, if the library is modified by someone else and passed on, the recipients should knowthat what they have is not the original version, so that the original author’s reputation will not beaffected by problems that might be introduced by others.Finally, software patents pose a constant threat to the existence of any free program. We wishto make sure that a company cannot effectively restrict the users of a free program by obtaininga restrictive license from a patent holder. Therefore, we insist that any patent license obtained fora version of the library must be consistent with the full freedom of use specified in this license.Most GNU software, including some libraries, is covered by the ordinary GNU GeneralPublicLicense. This license, the GNU Lesser General Public License, applies to certaindesignated libraries, and is quite different from the ordinary General Public License. We use thislicense for certain libraries in order to permit linking those libraries into non-free programs.When a program is linked with a library, whether statically or using a shared library, thecombination of the two is legally speaking a combined work, a derivative of the original library.The ordinary General Public License therefore permits such linking only if the entire combinationfits its criteria of freedom. The Lesser General Public License permits more lax criteria for linkingother code with the library.We call this license the “Lesser” General Public License because it does Less to protect theuser’s freedom than the ordinary General Public License. It also provides other free softwaredevelopers Less of an advantage over competing non-free programs. These disadvantages arethe reason we use the ordinary General Public License for many libraries. However, the Lesserlicense provides advantages in certain special circumstances.For example, on rare occasions, there may be a special need to encourage the widestpossible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-freeprograms must be allowed to use the library. A more frequent case is that a free library does thesame job as widely used non-free libraries. In this case, there is little to gain by limiting the freelibrary to free software only, so we use the Lesser General Public License.In other cases, permission to use a particular library in nonfree programs enables a greaternumber of people to use a large body of free software. For example, permission to use the GNUC Library in non-free programs enables many more people to use the whole GNU operatingsystem, as well as its variant, the GNU/Linux operating system.Although the Lesser General Public License is Less protective of the users’ freedom, itdoes ensure that the user of a program that is linked with the Library has the freedom and thewherewithal to run that program using a modified version of the Library.The precise terms and conditions for copying, distribution and modification follow. Pay closeattention to the difference between a “work based on the library” and a “work that uses thelibrary”. The former contains code derived from the library, whereas the latter must be combinedwith the library in order to run.GNU LESSER GENERAL PUBLIC LICENSE TERMS ANDCONDITIONS FOR COPYING, DISTRIBUTION ANDMODIFICATION0. This License Agreement applies to any software library or other program which containsa notice placed by the copyright holder or other authorized party saying it may be distributedunder the terms of this Lesser General Public License (also called “this License”). Each licenseeis addressed as “you”.A “library” means a collection of software functions and/or data prepared so as to beconveniently linked with application programs (which use some of those functions and data) toform executables.The “Library”, below, refers to any such software library or work which has been distributedunder these terms. A “work based on the Library” means either the Library or any derivative workunder copyright law: that is to say, a work containing the Library or a portion of it, either verbatimor with modifications and/or translated straightforwardly into another language. (Hereinafter,translation is included without limitation in the term “modification”.)“Source code” for a work means the preferred form of the work for making modifications toit. For a library, complete source code means all the source code for all modules it contains,plus any associated interface definition files, plus the scripts used to control compilation andinstallation of the library.Activities other than copying, distribution and modification are not covered by this License;they are outside its scope. The act of running a program using the Library is not restricted, andoutput from such a program is covered only if its contents constitute a work based on the Library(independent of the use of the Library in a tool for writing it). Whether that is true depends on whatthe Library does and what the program that uses the Library does.1. You may copy and distribute verbatim copies of the Library’s complete source code as youreceive it, in any medium, provided that you conspicuously and appropriately publish on eachcopy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices thatrefer to this License and to the absence of any warranty; and distribute a copy of this Licensealong with the Library.You may charge a fee for the physical act of transferring a copy, and you may at your optionoffer warranty protection in exchange for a fee.2. You may modify your copy or copies of the Library or any portion of it, thus forming a workbased on the Library, and copy and distribute such modifications or work under the terms ofSection 1 above, provided that you also meet all of these conditions:a) The modified work must itself be a software library.b) You must cause the files modified to carry prominent notices stating that you changedthe files and the date of any change.c) You must cause the whole of the work to be licensed at no charge to all third partiesunder the terms of this License.d) If a facility in the modified Library refers to a function or a table of data to be suppliedby an application program that uses the facility, other than as an argument passedwhen the facility is invoked, then you must make a good faith effort to ensure that,in the event an application does not supply such function or table, the facility stilloperates, and performs whatever part of its purpose remains meaningful.(For example, a function in a library to compute square roots has a purpose that isentirely well-defined independent of the application. Therefore, Subsection 2d requiresthat any application-supplied function or table used by this function must be optional:if the application does not supply it, the square root function must still computesquare roots.)These requirements apply to the modified work as a whole. If identifiable sections of that workare not derived from the Library, and can be reasonably considered independent and separateworks in themselves, then this License, and its terms, do not apply to those sections when youdistribute them as separate works. But when you distribute the same sections as part of a wholewhich is a work based on the Library, the distribution of the whole must be on the terms of thisLicense, whose permissions for other licensees extend to the entire whole, and thus to each andevery part regardless of who wrote it.Thus, it is not the intent of this section to claim rights or contest your rights to work writtenentirely by you; rather, the intent is to exercise the right to control the distribution of derivative orcollective works based on the Library.In addition, mere aggregation of another work not based on the Library with the Library (or witha work based on the Library) on a volume of a storage or distribution medium does not bring theother work under the scope of this License.3. You may opt to apply the terms of the ordinary GNU General Public License instead of thisLicense to a given copy of the Library. To do this, you must alter all the notices that refer to thisLicense, so that they refer to the ordinary GNU General Public License, version 2, instead of tothis License. (If a newer version than version 2 of the ordinary GNU General Public License hasappeared, then you can specify that version instead if you wish.) Do not make any other changein these notices.Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNUGeneral Public License applies to all subsequent copies and derivative works made from thatcopy.This option is useful when you wish to copy part of the code of the Library into a program thatis not a library.4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) inobject code or executable form under the terms of Sections 1 and 2 above provided that youaccompany it with the complete corresponding machinereadable source code, which mustbe distributed under the terms of Sections 1 and 2 above on a medium customarily used forsoftware interchange.If distribution of object code is made by offering access to copy from a designated place, thenoffering equivalent access to copy the source code from the same place satisfies the requirementto distribute the source code, even though third parties are not compelled to copy the sourcealong with the object code.5. A program that contains no derivative of any portion of the Library, but is designed to workwith the Library by being compiled or linked with it, is called a “work that uses the Library”. Sucha work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope ofthis License.However, linking a “work that uses the Library” with the Library creates an executable that isa derivative of the Library (because it contains portions of the Library), rather than a “work thatuses the library”. The executable is therefore covered by this License. Section 6 states terms fordistribution of such executables..When a “work that uses the Library” uses material from a header file that is part of the Library,the object code for the work may be a derivative work of the Library even though the sourcecode is not. Whether this is true is especially significant if the work can be linked without theLibrary, or if the work is itself a library. The threshold for this to be true is not precisely defined bylaw.エンドユーザーライセンスアグリーメント原文準備編資料75
