47ページYou may charge a fee for the physical act of transferring a copy, and you may at youroption offer warranty protection in exchange for a fee.2. You may modify your copy or copies of the Program or any portion of it, thus forming awork based on the Program, and copy and distribute such modifications or work underthe terms of Section 1 above, provided that you also meet all of these conditions:a) You must cause the modified files to carry prominent notices stating that you changedthe files and the date of any change.b) You must cause any work that you distribute or publish, that in whole or in partcontains or is derived from the Program or any part thereof, to be licensed as a wholeat no charge to all third parties under the terms of this License.c) If the modified program normally reads commands interactively when run, you mustcause it, when started running for such interactive use in the most ordinary way, toprint or display an announcement including an appropriate copyright notice and anotice that there is no warranty (or else, saying that you provide a warranty) and thatusers may redistribute the program under these conditions, and telling the user howto view a copy of this License. (Exception: if the Program itself is interactive but doesnot normally print such an announcement, your work based on the Program is notrequired to print an announcement.)These requirements apply to the modified work as a whole. If identifiable sections of thatwork are not derived from the Program, and can be reasonably considered independentand separate works in themselves, then this License, and its terms, do not apply to thosesections when you distribute them as separate works. But when you distribute the samesections as part of a whole which is a work based on the Program, the distribution of thewhole must be on the terms of this License, whose permissions for other licensees extendto the entire whole, and thus to each and every 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 ofderivative or collective works based on the Program.In addition, mere aggregation of another work not based on the Program with theProgram (or with a work based on the Program) on a volume of a storage or distributionmedium does not bring the other work under the scope of this License.3. You may copy and distribute the Program (or a work based on it, under Section 2) inobject code or executable form under the terms of Sections 1 and 2 above provided thatyou also do one of the following:a) Accompany it with the complete corresponding machine-readable source code,which must be distributed under the terms of Sections 1 and 2 above on a mediumcustomarily used for software interchange; or,b) Accompany it with a written offer, valid for at least three years, to give any third party,for a charge no more than your cost of physically performing source distribution, acomplete machine-readable copy of the corresponding source code, to be distributedunder the terms of Sections 1 and 2 above on a medium customarily used for softwareinterchange; or,c) Accompany it with the information you received as to the offer to distributecorresponding source code. (This alternative is allowed only for noncommercialdistribution and only if you received the program in object code or executable formwith such an offer, in accord with Subsection b above.)The source code for a work means the preferred form of the work for makingmodifications to it. For an executable work, complete source code means all the sourcecode for all modules it contains, plus any associated interface definition files, plus thescripts used to control compilation and installation of the executable. However, as aspecial exception, the source code distributed need not include anything that is normallydistributed (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 thatcomponent itself accompanies the executable.If distribution of executable or object code is made by offering access to copy from adesignated place, then offering equivalent access to copy the source code from thesame place counts as distribution of the source code, even though third parties are notcompelled to copy the source along with the object code.4. You may not copy, modify, sublicense, or distribute the Program except as expresslyprovided under this License. Any attempt otherwise to copy, modify, sublicense ordistribute the Program is void, and will automatically terminate your rights under thisLicense. However, parties who have received copies, or rights, from you under thisLicense will not have their licenses terminated so long as such parties remain in fullcompliance.5. You are not required to accept this License, since you have not signed it. However,nothing else grants you permission to modify or distribute the Program or its derivativeworks. These actions are prohibited by law if you do not accept this License. Therefore, bymodifying or distributing the Program (or any work based on the Program), you indicateyour acceptance of this License to do so, and all its terms and conditions for copying,distributing or modifying the Program or works based on it.6. Each time you redistribute the Program (or any work based on the Program), therecipient automatically receives a license from the original licensor to copy, distributeor modify the Program subject to these terms and conditions. You may not impose anyfurther restrictions on the recipients' exercise of the rights granted herein. You are notresponsible for enforcing compliance by third parties to this License.If any portion of this section is held invalid or unenforceable under any particularcircumstance, the balance of the section is intended to apply and the section as a wholeis intended to apply in other circumstances.It is not the purpose of this section to induce you to infringe any patents or otherproperty right claims or to contest validity of any such claims; this section has thesole purpose of protecting the integrity of the free software distribution system,which is implemented by public license practices. Many people have made generouscontributions to the wide range of software distributed through that system in relianceon consistent application of that system; it is up to the author/donor to decide if he orshe is willing to distribute software through any other system and a licensee cannotimpose that choice.This section is intended to make thoroughly clear what is believed to be a consequenceof the rest of this License.8. If the distribution and/or use of the Program is restricted in certain countries eitherby patents or by copyrighted interfaces, the original copyright holder who places theProgram under this License may add an explicit geographical distribution limitationexcluding those countries, so that distribution is permitted only in or among countriesnot thus excluded. In such case, this License incorporates the limitation as if written in thebody of this License.9. The Free Software Foundation may publish revised and/or new versions of the GeneralPublic License from time to time. Such new versions will be similar in spirit to the presentversion, but may differ in detail to address new problems or concerns.Each version is given a distinguishing version number. If the Program specifies a versionnumber of this License which applies to it and "any later version", you have the optionof following the terms and conditions either of that version or of any later versionpublished by the Free Software Foundation. If the Program does not specify a versionnumber of this License, you may choose any version ever published by the Free SoftwareFoundation.と意注NO WARRANTY11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTYFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPTWHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHERPARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHEREXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIESOF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK ASTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THEPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,REPAIR OR CORRECTION.12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITINGWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FORDAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIALDAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDINGBUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE ORLOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TOOPERATE WITH ANY OTHER 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 possible use tothe public, the best way to achieve this is to make it free software which everyone canredistribute and change under these terms.To do so, attach the following notices to the program. It is safest to attach them to thestart of each source file to most effectively convey the exclusion of warranty; and each fileshould 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 termsof the GNU General Public License as published by the Free Software Foundation; eitherversion 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 ANYWARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR APARTICULAR PURPOSE. See the GNU General Public License for more details.You should have received a copy of the GNU General Public License along with thisprogram; 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.7. If, as a consequence of a court judgment or allegation of patent infringement or for anyother reason (not limited to patent issues), conditions are imposed on you (whetherby 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 distribute soas to satisfy simultaneously your obligations under this License and any other pertinentobligations, then as a consequence you may not distribute the Program at all. Forexample, if a patent license would not permit royalty-free redistribution of the Programby all those who receive copies directly or indirectly through you, then the only way youcould satisfy both it and this License would be to refrain entirely from distribution of theProgram.ご10. If you wish to incorporate parts of the Program into other free programs whosedistribution conditions are different, write to the author to ask for permission. Forsoftware which is copyrighted by the Free Software Foundation, write to the FreeSoftware Foundation; we sometimes make exceptions for this. Our decision will beguided 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.If the program is interactive, make it output a short notice like this when it starts in aninteractive mode:Gnomovision version 69, Copyright (C) year name of author Gnomovision comes withABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you arewelcome to redistribute it under certain conditions; type `show c' for details.The hypothetical commands `show w' and `show c' should show the appropriate parts ofthe General Public License. Of course, the commands you use may be called something料資考参
