168 アサ フー タ ビースよくある質問3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code orexecutable form under the terms of Sections 1 and 2 above provided that you also do one of thefollowing:a) Accompany it with the complete corresponding machine-readable source code, which must bedistributed under the terms of Sections 1 and 2 above on a medium customarily used for softwareinterchange; or,b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge nomore than your cost of physically performing source distribution, a complete machine-readable copyof the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on amedium customarily used for software interchange; or,c) Accompany it with the information you received as to the offer to distribute corresponding sourcecode. (This alternative is allowed only for noncommercial distribution and only if you received theprogram in object code or executable form with such an offer, in accord with Subsection b above.)The source code for a work means the preferred form of the work for making modifications to it. For anexecutable work, complete source code means all the source code for all modules it contains, plus anyassociated interface definition files, plus the scripts used to control compilation and installation of theexecutable. However, as a special exception, the source code distributed need not include anythingthat is normally distributed (in either source or binary form) with the major components (compiler,kernel, and so on) of the operating system on which the executable runs, unless that component itselfaccompanies the executable.メッセージIf distribution of executable or object code is made by offering access to copy from a designated place,then offering equivalent access to copy the source code from the same place counts as distribution ofthe source code, even though third parties are not compelled to copy the source along with the objectcode.故障かな？4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided underthis License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, andwill automatically terminate your rights under this License. However, parties who have received copies,or rights, from you under this License will not have their licenses terminated so long as such partiesremain in full compliance.5. You are not required to accept this License, since you have not signed it. However, nothing else grantsyou permission to modify or distribute the Program or its derivative works. These actions are prohibitedby law if you do not accept this License. Therefore, by modifying or distributing the Program (or anywork based on the Program), you indicate your acceptance of this License to do so, and all its terms andconditions for copying, distributing or modifying the Program or works based on it.用語説6. Each time you redistribute the Program (or any work based on the Program), the recipient automaticallyreceives a license from the original licensor to copy, distribute or modify the Program subject to theseterms and conditions. You may not impose any further restrictions on the recipients' exercise of therights granted herein. You are not responsible for enforcing compliance by third parties to this License.明さくいん 本機で使われるソフトウェアのライセンス情報（つづき）ライセ情 ン報 ス7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason(not limited to patent issues), conditions are imposed on you (whether by court order, agreement orotherwise) that contradict the conditions of this License, they do not excuse you from the conditions ofthis License. If you cannot distribute so as to satisfy simultaneously your obligations under this Licenseand any other pertinent obligations, then as a consequence you may not distribute the Program at all.For example, if a patent license would not permit royalty-free redistribution of the Program by all thosewho receive copies directly or indirectly through you, then the only way you could satisfy both it andthis License would be to refrain entirely from distribution of the Program.If any portion of this section is held invalid or unenforceable under any particular circumstance, thebalance of the section is intended to apply and the section as a whole is intended to apply in othercircumstances.It is not the purpose of this section to induce you to infringe any patents or other property right claimsor to contest validity of any such claims; this section has the sole purpose of protecting the integrity ofthe free software distribution system, which is implemented by public license practices. Many peoplehave made generous contributions to the wide range of software distributed through that system inreliance on consistent application of that system; it is up to the author/donor to decide if he or she iswilling to distribute software through any other system and a licensee cannot impose that choice.This section is intended to make thoroughly clear what is believed to be a consequence of the rest ofthis License.8. If the distribution and/or use of the Program is restricted in certain countries either by patents or bycopyrighted interfaces, the original copyright holder who places the Program under this License mayadd an explicit geographical distribution limitation excluding those countries, so that distribution ispermitted only in or among countries not thus excluded. In such case, this License incorporates thelimitation as if written in the body of this License.9. The Free Software Foundation may publish revised and/or new versions of the General Public Licensefrom time to time. Such new versions will be similar in spirit to the present version, but may differ indetail to address new problems or concerns.Each version is given a distinguishing version number. If the Program specifies a version number of thisLicense which applies to it and "any later version", you have the option of following the terms andconditions either of that version or of any later version published by the Free Software Foundation. Ifthe Program does not specify a version number of this License, you may choose any version everpublished by the Free Software Foundation.10. If you wish to incorporate parts of the Program into other free programs whose distribution conditionsare different, write to the author to ask for permission. For software which is copyrighted by the FreeSoftware Foundation, write to the Free Software Foundation; we sometimes make exceptions for this.Our decision will be guided by the two goals of preserving the free status of all derivatives of our freesoftware and of promoting the sharing and reuse of software generally.NO WARRANTYEND 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 possible use to the public, the bestway to achieve this is to make it free software which everyone can redistribute and change under theseterms.To do so, attach the following notices to the program. It is safest to attach them to the start of each sourcefile to most effectively convey the exclusion of warranty; and each file should have at least the "copyright"line and a pointer to where 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 under the terms of the GNUGeneral Public License as published by the Free Software Foundation; either version 2 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; withouteven the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNUGeneral Public License for more details.You should have received a copy of the GNU General Public License along with this program; if not,write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.Also 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 starts in an interactive mode:Gnomovision version 69, Copyright (C) year name of authorGnomovision 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' fordetails.The hypothetical commands `show w' and `show c' should show the appropriate parts of the GeneralPublic License. Of course, the commands you use may be called something other than `show w' and`show c'; they could even be mouse-clicks or menu items--whatever suits your program.You should also get your employer (if you work as a programmer) or your school, 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 makespasses at compilers) written by James Hacker.<signature of Ty Coon>, 1 April 1989Ty Coon, President of ViceThis General Public License does not permit incorporating your program into proprietary programs. Ifyour program is a subroutine library, you may consider it more useful to permit linking proprietaryapplications with the library. If this is what you want to do, use the GNU Lesser General Public Licenseinstead of this License.Exhibit BLGPLGNU LESSER GENERAL PUBLIC LICENSEVersion 2.1, February 1999Copyright (C) 1991, 1999 Free Software Foundation, Inc.51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USAEveryone is permitted to copy and distribute verbatim copies of this license document, but changing itis not allowed.[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library PublicLicense, 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. Bycontrast, the GNU General Public Licenses are intended to guarantee your freedom to share and changefree software--to make sure the software is free for all its users.This license, the Lesser General Public License, applies to some specially designated software packages-typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use ittoo, but we suggest you first think carefully about whether this license or the ordinary General PublicLicense 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 Licensesare designed to make sure that you have the freedom to distribute copies of free software (and charge forthis service if you wish); that you receive source code or can get it if you want it; that you can change thesoftware and use pieces of it in new free programs; and that you are informed that you can do thesethings.To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or toask you to surrender these rights. These restrictions translate to certain responsibilities for you if youdistribute 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 give the recipientsall the rights that we gave you. You must make sure that they, too, receive or can get the source code. Ifyou link other code with the library, you must provide complete object files to the recipients, so that theycan relink them with the library after making changes to the library and recompiling it. And you mustshow them these terms so they know their rights.困11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM,TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THECOPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTYOF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIEDWARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK ASTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAMPROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.ったときWe protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you thislicense, which gives you legal permission to copy, distribute and/or modify the library.12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANYCOPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THEPROGRAM 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 USETHE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDEREDINACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TOOPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISEDOF THE POSSIBILITY OF SUCH DAMAGES.Finally, software patents pose a constant threat to the existence of any free program. We wish to makesure that a company cannot effectively restrict the users of a free program by obtaining a restrictivelicense 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 specified in this license.E4U20_21JD_book.indb 168To protect each distributor, we want to make it very clear that there is no warranty for the free library.Also, if the library is modified by someone else and passed on, the recipients should know that what theyhave is not the original version, so that the original author's reputation will not be affected by problemsthat might be introduced by others.Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. Thislicense, the GNU Lesser General Public License, applies to certain designated libraries, and is quitedifferent from the ordinary General Public License. We use this license for certain libraries in order topermit linking those libraries into non-free programs.2010/12/10 11:02:05
