著作権等について困 たとき171particular circumstance, the balance of the section is intended to apply and thesection as a whole is intended to apply in other circumstances.It is not the purpose of this section to induce you to infringe any patents orother property right claims or to contest validity of any such claims; this sectionhas the sole purpose of protecting the integrity of the free software distributionsystem, which is implemented by public license practices. Many people havemade generous contributions to the wide range of software distributed throughthat system in reliance on consistent application of that system; it is up to theauthor/donor to decide if he or she is willing to distribute software through anyother system and a licensee cannot impose that choice.This section is intended to make thoroughly clear what is believed to be aconsequence of the rest of this License.8. If the distribution and/or use of the Program is restricted in certain countrieseither by patents or by copyrighted interfaces, the original copyright holder whoplaces the Program under this License may add an explicit geographicaldistribution limitation excluding those countries, so that distribution is permittedonly in or among countries not thus excluded. In such case, this Licenseincorporates the limitation as if written in the body of this License.9. The Free Software Foundation may publish revised and/or new versions ofthe General Public License from time to time. Such new versions will be similarin spirit to the present version, but may differ in detail to address new problemsor concerns.Each version is given a distinguishing version number. If the Programspecifies a version number of this License which applies to it and "any laterversion", you have the option of following the terms and conditions either of thatversion or of any later version published by the Free Software Foundation. If theProgram does not specify a version number of this License, you may chooseany version ever published by the Free Software Foundation.10. If you wish to incorporate parts of the Program into other free programswhose distribution conditions are different, write to the author to ask forpermission. For software which is copyrighted by the Free SoftwareFoundation, write to the Free Software Foundation; we sometimes makeexceptions for this. Our decision will be guided by the two goals of preservingthe free status of all derivatives of our free software and of promoting thesharing and reuse of software generally.NO WARRANTY11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THEREIS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BYAPPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THECOPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THEPROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHEREXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THEIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR APARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY ANDPERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THEPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALLNECESSARY SERVICING, REPAIR OR CORRECTION.12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREEDTO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTYWHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM ASPERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANYGENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGESARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEINGRENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRDPARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANYOTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HASBEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.END OF TERMS AND CONDITIONSHow to Apply These Terms to Your New ProgramsIf you develop a new program, and you want it to be of the greatest possibleuse to the public, the best way to achieve this is to make it free software whicheveryone can redistribute and change under these terms.To do so, attach the following notices to the program. It is safest to attachthem to the start of each source file to most effectively convey the exclusion ofwarranty; and each file should have at least the "copyright" line and a pointer towhere the full notice is found.<one line to give the program's name and a brief idea of what it does.>Copyright (C) <year> <name of author>This program is free software; you can redistribute it and/or modify it underthe terms of the GNU General Public License as published by the FreeSoftware Foundation; either version 2 of the License, or (at your option) anylater version.This program is distributed in the hope that it will be useful, but WITHOUTANY WARRANTY; without even the implied warranty ofMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Seethe GNU General Public License for more details.You should have received a copy of the GNU General Public License alongwith this program; if not, write to the Free Software Foundation, Inc., 59Temple Place, Suite 330, Boston, MA 02111-1307 USAAlso add information on how to contact you by electronic and paper mail.If the program is interactive, make it output a short notice like this when it startsin an interactive mode:Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type'show w'. This is free software, and you are welcome to redistribute it undercertain conditions; type 'show c' for details.The hypothetical commands 'show w' and 'show c' should show theappropriate parts of the General Public License. Of course, the commands youuse may be called something other than 'show w' and 'show c'; they could evenbe mouse-clicks or menu items-whatever suits your program.You should also get your employer (if you work as a programmer) or yourschool, if any, to sign a "copyright disclaimer" for the program, if necessary.Here is a sample; alter the names:Yoyodyne, Inc., hereby disclaims all copyright interest in the program'Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of ViceThis General Public License does not permit incorporating your program intoproprietary programs. If your program is a subroutine library, you may considerit more useful to permit linking proprietary applications with the library. If this iswhat you want to do, use the GNU Library General Public License instead of thisLicense.GNU LESSER GENERAL PUBLIC LICENSEVersion 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc.59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this licensedocument, but changing it is not allowed.[This is the first released version of the Lesser GPL. It also counts as thesuccessor of the GNU Library Public License, version 2, hence the versionnumber 2.1.]Preamble The licenses for most software are designed to take away your freedom toshare and change it. By contrast, the GNU General Public Licenses areintended to guarantee your freedom to share and change free software--to makesure the software is free for all its users. This license, the Lesser General Public License, applies to some speciallydesignated software packages--typically libraries--of the Free SoftwareFoundation and other authors who decide to use it. You can use it too, but wesuggest you first think carefully about whether this license or the ordinaryGeneral Public License is the better strategy to use in any particular case,based on the explanations below. When we speak of free software, we are referring to freedom of use, not price.Our General Public Licenses are designed to make sure that you have thefreedom to distribute copies of free software (and charge for this service if youwish); that you receive 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 areinformed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors todeny you these rights or to ask you to surrender these rights. These restrictionstranslate to certain responsibilities for you if you distribute copies of the library orif you modify it.For example, if you distribute copies of the library, whether gratis or for a fee,you must give the recipients all the rights that we gave you. You must makesure that they, too, receive or can get the source code. If you link other codewith the library, you must provide complete object files to the recipients, so thatthey can relink them with the library after making changes to the library andrecompiling 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 offer you this license, which gives you legal permission to copy, distributeand/or modify the library. To protect each distributor, we want to make it very clear that there is nowarranty for the free library. Also, if the library is modified by someone else andpassed on, the recipients should know that what they have is not the originalversion, so that the original author's reputation will not be affected by problemsthat might be introduced by others.Finally, software patents pose a constant threat to the existence of any freeprogram. We wish to make sure that a company cannot effectively restrict theusers of a free program by obtaining a restrictive license from a patent holder.Therefore, we insist that any patent license obtained for a version of the librarymust be consistent with the full freedom of use specified in this license.Most GNU software, including some libraries, is covered by the ordinary GNUGeneral Public License. This license, the GNU Lesser General Public License,applies to certain designated libraries, and is quite different from the ordinaryGeneral Public License. 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 statically or using a shared
