.By contrast, the GNU General Public License is intended to guarantee yourfreedom to share and change free software to make sure the software is free for all itsusers.This General Public License applies to most of the Free Software Foundation ssoftware and to any other program whose authors commit to using it.(Some otherFree Software Foundation software is covered by the GNU Library General PublicLicense instead.) You can apply it to your programs, too.When we speak of free software, we are referring to freedom, not price.Our GeneralPublic Licenses are designed to make sure that you have the freedom to distributecopies of free software (and charge for this service if you wish), that you receivesource code or can get it if you want it, that you can change the software or usepieces of it in new free programs; and that you know you can do these things.To protect your rights, we need to make restrictions that forbid anyone to deny youthese rights or to ask you to surrender the rights.These restrictions translate to certainresponsibilities for you if you distribute copies of the software, or if you modify it.For example, if you distribute copies of such a program, whether gratis or for a fee,you must give the recipients all the rights that you have.You must make sure thatthey, too, receive or can get the source code.And you must show them these termsso they know their rights.We protect your rights with two steps: (1) copyright the software, and (2) offer youthis license which gives you legal permission to copy, distribute and/or modify thesoftware.Also, for each author s protection and ours, we want to make certain that everyoneunderstands that there is no warranty for this free software.If the software is modi-fied by someone else and passed on, we want its recipients to know that what theyhave is not the original, so that any problems introduced by others will not reflect onthe original authors reputations.Finally, any free program is threatened constantly by software patents.We wish toavoid the danger that redistributors of a free program will individually obtain patentlicenses, in effect making the program proprietary.To prevent this, we have made itclear that any patent must be licensed for everyone s free use or not licensed at all.The precise terms and conditions for copying, distribution and modification follow.1.TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION ANDMODIFICATION1.This License applies to any program or other work which contains a noticeplaced by the copyright holder saying it may be distributed under the termsof this General Public License.The "Program", below, refers to any such pro-gram or work, and a "work based on the Program" means either the Programor any derivative work under copyright law: that is to say, a work containingthe Program or a portion of it, either verbatim or with modifications and/ortranslated into another language.(Hereinafter, translation is included withoutlimitation in the term "modification".) Each licensee is addressed as "you".Activities other than copying, distribution and modification are not coveredby this License; they are outside its scope.The act of running the Program isnot restricted, and the output from the Program is covered only if its contents63 Generalbeen made byconstitute a work based on the ProgramAppendix H.GNUhaving Public License(independent ofrunning the Program).Whether that is true depends on what the Program does.2.You may copy and distribute verbatim copies of the Program s source code asyou receive it, in any medium, provided that you conspicuously and appropri-ately publish on each copy an appropriate copyright notice and disclaimer ofwarranty; keep intact all the notices that refer to this License and to the absenceof any warranty; and give any other recipients of the Program a copy of thisLicense along with the Program.You may charge a fee for the physical act of transferring a copy, and you may atyour option offer warranty protection in exchange for a fee.3.You may modify your copy or copies of the Program or any portion of it, thusforming a work based on the Program, and copy and distribute such modifica-tions or work under the terms of Section 1 above, provided that you also meetall of these conditions:1.You must cause the modified files to carry prominent notices stating thatyou changed the files and the date of any change.2.You must cause any work that you distribute or publish, that in whole orin part contains or is derived from the Program or any part thereof, to belicensed as a whole at no charge to all third parties under the terms of thisLicense.3.If the modified program normally reads commands interactively whenrun, you must cause it, when started running for such interactive use inthe most ordinary way, to print or display an announcement includingan appropriate copyright notice and a notice that there is no warranty (orelse, saying that you provide a warranty) and that users may redistributethe program under these conditions, and telling the user how to view acopy of this License.(Exception: if the Program itself is interactive butdoes not normally print such an announcement, your work based on theProgram is not required to print an announcement.)These requirements apply to the modified work as a whole.If identifiable sec-tions of that work are not derived from the Program, and can be reasonablyconsidered independent and separate works in themselves, then this License,and its terms, do not apply to those sections when you distribute them as sepa-rate works.But when you distribute the same sections as part of a whole whichis a work based on the Program, the distribution of the whole must be on theterms of this License, whose permissions for other licensees extend to the entirewhole, 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 towork written entirely by you; rather, the intent is to exercise the right to controlthe distribution of derivative or collective works based on the Program.In addition, mere aggregation of another work not based on the Program withthe Program (or with a work based on the Program) on a volume of a storageor distribution medium does not bring the other work under the scope of thisLicense.4.You may copy and distribute the Program (or a work based on it, under Section2) in object code or executable form under the terms of Sections 1 and 2 aboveprovided that you also do one of the following:A.Accompany it with the complete corresponding machine-readable sourcecode, which must be distributed under the terms of Sections 1 and 2 aboveon a medium customarily used for software interchange; or,B.Accompany it with a written offer, valid for at least three years, to give anythird party, for a charge no more than your cost of physically perform-ing source distribution, a complete machine-readable copy of the corre-sponding source code, to be distributed under the terms of Sections 1 and2 above on a medium customarily used for software interchange; or,64 Appendix H.GNUas offer to dis-GeneralC.Accompany it with the information you received to thePublic Licensetribute corresponding source code
