By contrast, the GNU General Public 13*2587624eSSzymon OlewniczakLicense is intended to guarantee your freedom to share and change free 14*2587624eSSzymon Olewniczaksoftware--to make sure the software is free for all its users. This 15*2587624eSSzymon OlewniczakGeneral Public License applies to most of the Free Software 16*2587624eSSzymon OlewniczakFoundation's software and to any other program whose authors commit to 17*2587624eSSzymon Olewniczakusing it. (Some other Free Software Foundation software is covered by 18*2587624eSSzymon Olewniczakthe GNU Lesser General Public License instead.) You can apply it to 19*2587624eSSzymon Olewniczakyour programs, too. 20*2587624eSSzymon Olewniczak 21*2587624eSSzymon Olewniczak When we speak of free software, we are referring to freedom, not 22*2587624eSSzymon Olewniczakprice. Our General Public Licenses are designed to make sure that you 23*2587624eSSzymon Olewniczakhave the freedom to distribute copies of free software (and charge for 24*2587624eSSzymon Olewniczakthis service if you wish), that you receive source code or can get it 25*2587624eSSzymon Olewniczakif you want it, that you can change the software or use pieces of it 26*2587624eSSzymon Olewniczakin new free programs; and that you know you can do these things. 27*2587624eSSzymon Olewniczak 28*2587624eSSzymon Olewniczak To protect your rights, we need to make restrictions that forbid 29*2587624eSSzymon Olewniczakanyone to deny you these rights or to ask you to surrender the rights. 30*2587624eSSzymon OlewniczakThese restrictions translate to certain responsibilities for you if you 31*2587624eSSzymon Olewniczakdistribute copies of the software, or if you modify it. 32*2587624eSSzymon Olewniczak 33*2587624eSSzymon Olewniczak For example, if you distribute copies of such a program, whether 34*2587624eSSzymon Olewniczakgratis or for a fee, you must give the recipients all the rights that 35*2587624eSSzymon Olewniczakyou have. You must make sure that they, too, receive or can get the 36*2587624eSSzymon Olewniczaksource code. And you must show them these terms so they know their 37*2587624eSSzymon Olewniczakrights. 38*2587624eSSzymon Olewniczak 39*2587624eSSzymon Olewniczak We protect your rights with two steps: (1) copyright the software, and 40*2587624eSSzymon Olewniczak(2) offer you this license which gives you legal permission to copy, 41*2587624eSSzymon Olewniczakdistribute and/or modify the software. 42*2587624eSSzymon Olewniczak 43*2587624eSSzymon Olewniczak Also, for each author's protection and ours, we want to make certain 44*2587624eSSzymon Olewniczakthat everyone understands that there is no warranty for this free 45*2587624eSSzymon Olewniczaksoftware. If the software is modified by someone else and passed on, we 46*2587624eSSzymon Olewniczakwant its recipients to know that what they have is not the original, so 47*2587624eSSzymon Olewniczakthat any problems introduced by others will not reflect on the original 48*2587624eSSzymon Olewniczakauthors' reputations. 49*2587624eSSzymon Olewniczak 50*2587624eSSzymon Olewniczak Finally, any free program is threatened constantly by software 51*2587624eSSzymon Olewniczakpatents. We wish to avoid the danger that redistributors of a free 52*2587624eSSzymon Olewniczakprogram will individually obtain patent licenses, in effect making the 53*2587624eSSzymon Olewniczakprogram proprietary. To prevent this, we have made it clear that any 54*2587624eSSzymon Olewniczakpatent must be licensed for everyone's free use or not licensed at all. 55*2587624eSSzymon Olewniczak 56*2587624eSSzymon Olewniczak The precise terms and conditions for copying, distribution and 57*2587624eSSzymon Olewniczakmodification follow. 58*2587624eSSzymon Olewniczak 59*2587624eSSzymon Olewniczak GNU GENERAL PUBLIC LICENSE 60*2587624eSSzymon Olewniczak TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*2587624eSSzymon Olewniczak 62*2587624eSSzymon Olewniczak 0. This License applies to any program or other work which contains 63*2587624eSSzymon Olewniczaka notice placed by the copyright holder saying it may be distributed 64*2587624eSSzymon Olewniczakunder the terms of this General Public License. The "Program", below, 65*2587624eSSzymon Olewniczakrefers to any such program or work, and a "work based on the Program" 66*2587624eSSzymon Olewniczakmeans either the Program or any derivative work under copyright law: 67*2587624eSSzymon Olewniczakthat is to say, a work containing the Program or a portion of it, 68*2587624eSSzymon Olewniczakeither verbatim or with modifications and/or translated into another 69*2587624eSSzymon Olewniczaklanguage. (Hereinafter, translation is included without limitation in 70*2587624eSSzymon Olewniczakthe term "modification".) Each licensee is addressed as "you". 71*2587624eSSzymon Olewniczak 72*2587624eSSzymon OlewniczakActivities other than copying, distribution and modification are not 73*2587624eSSzymon Olewniczakcovered by this License; they are outside its scope. The act of 74*2587624eSSzymon Olewniczakrunning the Program is not restricted, and the output from the Program 75*2587624eSSzymon Olewniczakis covered only if its contents constitute a work based on the 76*2587624eSSzymon OlewniczakProgram (independent of having been made by running the Program). 77*2587624eSSzymon OlewniczakWhether that is true depends on what the Program does. 78*2587624eSSzymon Olewniczak 79*2587624eSSzymon Olewniczak 1. You may copy and distribute verbatim copies of the Program's 80*2587624eSSzymon Olewniczaksource code as you receive it, in any medium, provided that you 81*2587624eSSzymon Olewniczakconspicuously and appropriately publish on each copy an appropriate 82*2587624eSSzymon Olewniczakcopyright notice and disclaimer of warranty; keep intact all the 83*2587624eSSzymon Olewniczaknotices that refer to this License and to the absence of any warranty; 84*2587624eSSzymon Olewniczakand give any other recipients of the Program a copy of this License 85*2587624eSSzymon Olewniczakalong with the Program. 86*2587624eSSzymon Olewniczak 87*2587624eSSzymon OlewniczakYou may charge a fee for the physical act of transferring a copy, and 88*2587624eSSzymon Olewniczakyou may at your option offer warranty protection in exchange for a fee. 89*2587624eSSzymon Olewniczak 90*2587624eSSzymon Olewniczak 2. You may modify your copy or copies of the Program or any portion 91*2587624eSSzymon Olewniczakof it, thus forming a work based on the Program, and copy and 92*2587624eSSzymon Olewniczakdistribute such modifications or work under the terms of Section 1 93*2587624eSSzymon Olewniczakabove, provided that you also meet all of these conditions: 94*2587624eSSzymon Olewniczak 95*2587624eSSzymon Olewniczak a) You must cause the modified files to carry prominent notices 96*2587624eSSzymon Olewniczak stating that you changed the files and the date of any change. 97*2587624eSSzymon Olewniczak 98*2587624eSSzymon Olewniczak b) You must cause any work that you distribute or publish, that in 99*2587624eSSzymon Olewniczak whole or in part contains or is derived from the Program or any 100*2587624eSSzymon Olewniczak part thereof, to be licensed as a whole at no charge to all third 101*2587624eSSzymon Olewniczak parties under the terms of this License. 102*2587624eSSzymon Olewniczak 103*2587624eSSzymon Olewniczak c) If the modified program normally reads commands interactively 104*2587624eSSzymon Olewniczak when run, you must cause it, when started running for such 105*2587624eSSzymon Olewniczak interactive use in the most ordinary way, to print or display an 106*2587624eSSzymon Olewniczak announcement including an appropriate copyright notice and a 107*2587624eSSzymon Olewniczak notice that there is no warranty (or else, saying that you provide 108*2587624eSSzymon Olewniczak a warranty) and that users may redistribute the program under 109*2587624eSSzymon Olewniczak these conditions, and telling the user how to view a copy of this 110*2587624eSSzymon Olewniczak License. (Exception: if the Program itself is interactive but 111*2587624eSSzymon Olewniczak does not normally print such an announcement, your work based on 112*2587624eSSzymon Olewniczak the Program is not required to print an announcement.) 113*2587624eSSzymon Olewniczak 114*2587624eSSzymon OlewniczakThese requirements apply to the modified work as a whole. If 115*2587624eSSzymon Olewniczakidentifiable sections of that work are not derived from the Program, 116*2587624eSSzymon Olewniczakand can be reasonably considered independent and separate works in 117*2587624eSSzymon Olewniczakthemselves, then this License, and its terms, do not apply to those 118*2587624eSSzymon Olewniczaksections when you distribute them as separate works. But when you 119*2587624eSSzymon Olewniczakdistribute the same sections as part of a whole which is a work based 120*2587624eSSzymon Olewniczakon the Program, the distribution of the whole must be on the terms of 121*2587624eSSzymon Olewniczakthis License, whose permissions for other licensees extend to the 122*2587624eSSzymon Olewniczakentire whole, and thus to each and every part regardless of who wrote it. 123*2587624eSSzymon Olewniczak 124*2587624eSSzymon OlewniczakThus, it is not the intent of this section to claim rights or contest 125*2587624eSSzymon Olewniczakyour rights to work written entirely by you; rather, the intent is to 126*2587624eSSzymon Olewniczakexercise the right to control the distribution of derivative or 127*2587624eSSzymon Olewniczakcollective works based on the Program. 128*2587624eSSzymon Olewniczak 129*2587624eSSzymon OlewniczakIn addition, mere aggregation of another work not based on the Program 130*2587624eSSzymon Olewniczakwith the Program (or with a work based on the Program) on a volume of 131*2587624eSSzymon Olewniczaka storage or distribution medium does not bring the other work under 132*2587624eSSzymon Olewniczakthe scope of this License. 133*2587624eSSzymon Olewniczak 134*2587624eSSzymon Olewniczak 3. You may copy and distribute the Program (or a work based on it, 135*2587624eSSzymon Olewniczakunder Section 2) in object code or executable form under the terms of 136*2587624eSSzymon OlewniczakSections 1 and 2 above provided that you also do one of the following: 137*2587624eSSzymon Olewniczak 138*2587624eSSzymon Olewniczak a) Accompany it with the complete corresponding machine-readable 139*2587624eSSzymon Olewniczak source code, which must be distributed under the terms of Sections 140*2587624eSSzymon Olewniczak 1 and 2 above on a medium customarily used for software interchange; or, 141*2587624eSSzymon Olewniczak 142*2587624eSSzymon Olewniczak b) Accompany it with a written offer, valid for at least three 143*2587624eSSzymon Olewniczak years, to give any third party, for a charge no more than your 144*2587624eSSzymon Olewniczak cost of physically performing source distribution, a complete 145*2587624eSSzymon Olewniczak machine-readable copy of the corresponding source code, to be 146*2587624eSSzymon Olewniczak distributed under the terms of Sections 1 and 2 above on a medium 147*2587624eSSzymon Olewniczak customarily used for software interchange; or, 148*2587624eSSzymon Olewniczak 149*2587624eSSzymon Olewniczak c) Accompany it with the information you received as to the offer 150*2587624eSSzymon Olewniczak to distribute corresponding source code. (This alternative is 151*2587624eSSzymon Olewniczak allowed only for noncommercial distribution and only if you 152*2587624eSSzymon Olewniczak received the program in object code or executable form with such 153*2587624eSSzymon Olewniczak an offer, in accord with Subsection b above.) 154*2587624eSSzymon Olewniczak 155*2587624eSSzymon OlewniczakThe source code for a work means the preferred form of the work for 156*2587624eSSzymon Olewniczakmaking modifications to it. For an executable work, complete source 157*2587624eSSzymon Olewniczakcode means all the source code for all modules it contains, plus any 158*2587624eSSzymon Olewniczakassociated interface definition files, plus the scripts used to 159*2587624eSSzymon Olewniczakcontrol compilation and installation of the executable. However, as a 160*2587624eSSzymon Olewniczakspecial exception, the source code distributed need not include 161*2587624eSSzymon Olewniczakanything that is normally distributed (in either source or binary 162*2587624eSSzymon Olewniczakform) with the major components (compiler, kernel, and so on) of the 163*2587624eSSzymon Olewniczakoperating system on which the executable runs, unless that component 164*2587624eSSzymon Olewniczakitself accompanies the executable. 165*2587624eSSzymon Olewniczak 166*2587624eSSzymon OlewniczakIf distribution of executable or object code is made by offering 167*2587624eSSzymon Olewniczakaccess to copy from a designated place, then offering equivalent 168*2587624eSSzymon Olewniczakaccess to copy the source code from the same place counts as 169*2587624eSSzymon Olewniczakdistribution of the source code, even though third parties are not 170*2587624eSSzymon Olewniczakcompelled to copy the source along with the object code. 171*2587624eSSzymon Olewniczak 172*2587624eSSzymon Olewniczak 4. You may not copy, modify, sublicense, or distribute the Program 173*2587624eSSzymon Olewniczakexcept as expressly provided under this License. Any attempt 174*2587624eSSzymon Olewniczakotherwise to copy, modify, sublicense or distribute the Program is 175*2587624eSSzymon Olewniczakvoid, and will automatically terminate your rights under this License. 176*2587624eSSzymon OlewniczakHowever, parties who have received copies, or rights, from you under 177*2587624eSSzymon Olewniczakthis License will not have their licenses terminated so long as such 178*2587624eSSzymon Olewniczakparties remain in full compliance. 179*2587624eSSzymon Olewniczak 180*2587624eSSzymon Olewniczak 5. You are not required to accept this License, since you have not 181*2587624eSSzymon Olewniczaksigned it. However, nothing else grants you permission to modify or 182*2587624eSSzymon Olewniczakdistribute the Program or its derivative works. These actions are 183*2587624eSSzymon Olewniczakprohibited by law if you do not accept this License. Therefore, by 184*2587624eSSzymon Olewniczakmodifying or distributing the Program (or any work based on the 185*2587624eSSzymon OlewniczakProgram), you indicate your acceptance of this License to do so, and 186*2587624eSSzymon Olewniczakall its terms and conditions for copying, distributing or modifying 187*2587624eSSzymon Olewniczakthe Program or works based on it. 188*2587624eSSzymon Olewniczak 189*2587624eSSzymon Olewniczak 6. Each time you redistribute the Program (or any work based on the 190*2587624eSSzymon OlewniczakProgram), the recipient automatically receives a license from the 191*2587624eSSzymon Olewniczakoriginal licensor to copy, distribute or modify the Program subject to 192*2587624eSSzymon Olewniczakthese terms and conditions. You may not impose any further 193*2587624eSSzymon Olewniczakrestrictions on the recipients' exercise of the rights granted herein. 194*2587624eSSzymon OlewniczakYou are not responsible for enforcing compliance by third parties to 195*2587624eSSzymon Olewniczakthis License. 196*2587624eSSzymon Olewniczak 197*2587624eSSzymon Olewniczak 7. If, as a consequence of a court judgment or allegation of patent 198*2587624eSSzymon Olewniczakinfringement or for any other reason (not limited to patent issues), 199*2587624eSSzymon Olewniczakconditions are imposed on you (whether by court order, agreement or 200*2587624eSSzymon Olewniczakotherwise) that contradict the conditions of this License, they do not 201*2587624eSSzymon Olewniczakexcuse you from the conditions of this License. If you cannot 202*2587624eSSzymon Olewniczakdistribute so as to satisfy simultaneously your obligations under this 203*2587624eSSzymon OlewniczakLicense and any other pertinent obligations, then as a consequence you 204*2587624eSSzymon Olewniczakmay not distribute the Program at all. For example, if a patent 205*2587624eSSzymon Olewniczaklicense would not permit royalty-free redistribution of the Program by 206*2587624eSSzymon Olewniczakall those who receive copies directly or indirectly through you, then 207*2587624eSSzymon Olewniczakthe only way you could satisfy both it and this License would be to 208*2587624eSSzymon Olewniczakrefrain entirely from distribution of the Program. 209*2587624eSSzymon Olewniczak 210*2587624eSSzymon OlewniczakIf any portion of this section is held invalid or unenforceable under 211*2587624eSSzymon Olewniczakany particular circumstance, the balance of the section is intended to 212*2587624eSSzymon Olewniczakapply and the section as a whole is intended to apply in other 213*2587624eSSzymon Olewniczakcircumstances. 214*2587624eSSzymon Olewniczak 215*2587624eSSzymon OlewniczakIt is not the purpose of this section to induce you to infringe any 216*2587624eSSzymon Olewniczakpatents or other property right claims or to contest validity of any 217*2587624eSSzymon Olewniczaksuch claims; this section has the sole purpose of protecting the 218*2587624eSSzymon Olewniczakintegrity of the free software distribution system, which is 219*2587624eSSzymon Olewniczakimplemented by public license practices. Many people have made 220*2587624eSSzymon Olewniczakgenerous contributions to the wide range of software distributed 221*2587624eSSzymon Olewniczakthrough that system in reliance on consistent application of that 222*2587624eSSzymon Olewniczaksystem; it is up to the author/donor to decide if he or she is willing 223*2587624eSSzymon Olewniczakto distribute software through any other system and a licensee cannot 224*2587624eSSzymon Olewniczakimpose that choice. 225*2587624eSSzymon Olewniczak 226*2587624eSSzymon OlewniczakThis section is intended to make thoroughly clear what is believed to 227*2587624eSSzymon Olewniczakbe a consequence of the rest of this License. 228*2587624eSSzymon Olewniczak 229*2587624eSSzymon Olewniczak 8. If the distribution and/or use of the Program is restricted in 230*2587624eSSzymon Olewniczakcertain countries either by patents or by copyrighted interfaces, the 231*2587624eSSzymon Olewniczakoriginal copyright holder who places the Program under this License 232*2587624eSSzymon Olewniczakmay add an explicit geographical distribution limitation excluding 233*2587624eSSzymon Olewniczakthose countries, so that distribution is permitted only in or among 234*2587624eSSzymon Olewniczakcountries not thus excluded. In such case, this License incorporates 235*2587624eSSzymon Olewniczakthe limitation as if written in the body of this License. 236*2587624eSSzymon Olewniczak 237*2587624eSSzymon Olewniczak 9. The Free Software Foundation may publish revised and/or new versions 238*2587624eSSzymon Olewniczakof the General Public License from time to time. Such new versions will 239*2587624eSSzymon Olewniczakbe similar in spirit to the present version, but may differ in detail to 240*2587624eSSzymon Olewniczakaddress new problems or concerns. 241*2587624eSSzymon Olewniczak 242*2587624eSSzymon OlewniczakEach version is given a distinguishing version number. If the Program 243*2587624eSSzymon Olewniczakspecifies a version number of this License which applies to it and "any 244*2587624eSSzymon Olewniczaklater version", you have the option of following the terms and conditions 245*2587624eSSzymon Olewniczakeither of that version or of any later version published by the Free 246*2587624eSSzymon OlewniczakSoftware Foundation. If the Program does not specify a version number of 247*2587624eSSzymon Olewniczakthis License, you may choose any version ever published by the Free Software 248*2587624eSSzymon OlewniczakFoundation. 249*2587624eSSzymon Olewniczak 250*2587624eSSzymon Olewniczak 10. If you wish to incorporate parts of the Program into other free 251*2587624eSSzymon Olewniczakprograms whose distribution conditions are different, write to the author 252*2587624eSSzymon Olewniczakto ask for permission. For software which is copyrighted by the Free 253*2587624eSSzymon OlewniczakSoftware Foundation, write to the Free Software Foundation; we sometimes 254*2587624eSSzymon Olewniczakmake exceptions for this. Our decision will be guided by the two goals 255*2587624eSSzymon Olewniczakof preserving the free status of all derivatives of our free software and 256*2587624eSSzymon Olewniczakof promoting the sharing and reuse of software generally. 257*2587624eSSzymon Olewniczak 258*2587624eSSzymon Olewniczak NO WARRANTY 259*2587624eSSzymon Olewniczak 260*2587624eSSzymon Olewniczak 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*2587624eSSzymon OlewniczakFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*2587624eSSzymon OlewniczakOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*2587624eSSzymon OlewniczakPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*2587624eSSzymon OlewniczakOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*2587624eSSzymon OlewniczakMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
