It alsocounts as the successor of the GNU Library Public License,version 2, hence the version number 2.1.]PreambleThe licenses for most software are designed to take away yourfreedom to share and change it. By contrast, the GNU GeneralPublic Licenses are intended to guarantee your freedom to shareand change free software – to make sure the software is free forall its users.This license, the Lesser General Public License, applies to somespecially designated software packages – typically libraries – ofthe Free Software Foundation and other authors who decide touse it. You can use it too, but we suggest you first think carefullyabout whether this license or the ordinary General Public Licenseis the better strategy to use in any particular case, based on theexplanations below.When we speak of free software, we are referring to freedomof use, not price. Our General Public Licenses are designed tomake sure that you have the freedom to distribute copies offree software (and charge for this service if you wish); that youreceive source code or can get it if you want it; that you canchange the software and use pieces of it in new free programs;and that you are informed that you can do these things.To protect your rights, we need to make restrictions that forbiddistributors to deny you these rights or to ask you to surrenderthese rights. These restrictions translate to certain responsibilitiesfor you if you distribute copies of the library or if you modify it.For example, if you distribute copies of the library, whethergratis or for a fee, you must give the recipients all the rights thatwe gave you. You must make sure that they, too, receive orcan get the source code. If you link other code with the library,you must provide complete object files to the recipients, so thatthey can relink them with the library after making changes to thelibrary and recompiling it. And you must show them these termsso they know their rights.We protect your rights with a two-step method: (1) wecopyright the library, and (2) we offer you this license, whichgives you legal permission to copy, distribute and/or modify thelibrary.To protect each distributor, we want to make it very clearthat there is no warranty for the free library. Also, if the library ismodified by someone else and passed on, the recipients shouldknow that what they have is not the original version, so that theoriginal author’s reputation will not be affected by problems thatmight be introduced by others.Finally, software patents pose a constant threat to theexistence of any free program. We wish to make sure that acompany cannot effectively restrict the users of a free programby obtaining a restrictive license from a patent holder. Therefore,we insist that any patent license obtained for a version of thelibrary must be consistent with the full freedom of use specifiedin this license.Most GNU software, including some libraries, is covered bythe ordinary GNU General PublicLicense. This license, the GNULesser General Public License, applies to certain designatedlibraries, and is quite different from the ordinary General PublicLicense. We use this license for certain libraries in order topermit linking those libraries into non-free programs.When a program is linked with a library, whether staticallyor using a shared library, the combination of the two is legallyspeaking a combined work, a derivative of the original library.The ordinary General Public License therefore permits suchlinking only if the entire combination fits its criteria of freedom.The Lesser General Public License permits more lax criteria forlinking other code with the library.We call this license the “Lesser” General Public Licensebecause it does Less to protect the user’s freedom than theordinary General Public License. It also provides other freesoftware developers Less of an advantage over competing nonfree programs. These disadvantages are the reason we use theordinary General Public License for many libraries. However,the Lesser license provides advantages in certain specialcircumstances.For example, on rare occasions, there may be a special needto encourage the widest possible use of a certain library, sothat it becomes a de-facto standard. To achieve this, non-freeprograms must be allowed to use the library. A more frequentcase is that a free library does the same job as widely used nonfree libraries. In this case, there is little to gain by limiting the freelibrary to free software only, so we use the Lesser General PublicLicense.In other cases, permission to use a particular library in nonfreeprograms enables a greater number of people to use a large資料エンドユーザーライセンスアグリーメント原文87
