By contrast, the GNU General Public 13*2a48e470SMemoryShoreLicense is intended to guarantee your freedom to share and change free 14*2a48e470SMemoryShoresoftware--to make sure the software is free for all its users. This 15*2a48e470SMemoryShoreGeneral Public License applies to most of the Free Software 16*2a48e470SMemoryShoreFoundation's software and to any other program whose authors commit to 17*2a48e470SMemoryShoreusing it. (Some other Free Software Foundation software is covered by 18*2a48e470SMemoryShorethe GNU Lesser General Public License instead.) You can apply it to 19*2a48e470SMemoryShoreyour programs, too. 20*2a48e470SMemoryShore 21*2a48e470SMemoryShore When we speak of free software, we are referring to freedom, not 22*2a48e470SMemoryShoreprice. Our General Public Licenses are designed to make sure that you 23*2a48e470SMemoryShorehave the freedom to distribute copies of free software (and charge for 24*2a48e470SMemoryShorethis service if you wish), that you receive source code or can get it 25*2a48e470SMemoryShoreif you want it, that you can change the software or use pieces of it 26*2a48e470SMemoryShorein new free programs; and that you know you can do these things. 27*2a48e470SMemoryShore 28*2a48e470SMemoryShore To protect your rights, we need to make restrictions that forbid 29*2a48e470SMemoryShoreanyone to deny you these rights or to ask you to surrender the rights. 30*2a48e470SMemoryShoreThese restrictions translate to certain responsibilities for you if you 31*2a48e470SMemoryShoredistribute copies of the software, or if you modify it. 32*2a48e470SMemoryShore 33*2a48e470SMemoryShore For example, if you distribute copies of such a program, whether 34*2a48e470SMemoryShoregratis or for a fee, you must give the recipients all the rights that 35*2a48e470SMemoryShoreyou have. You must make sure that they, too, receive or can get the 36*2a48e470SMemoryShoresource code. And you must show them these terms so they know their 37*2a48e470SMemoryShorerights. 38*2a48e470SMemoryShore 39*2a48e470SMemoryShore We protect your rights with two steps: (1) copyright the software, and 40*2a48e470SMemoryShore(2) offer you this license which gives you legal permission to copy, 41*2a48e470SMemoryShoredistribute and/or modify the software. 42*2a48e470SMemoryShore 43*2a48e470SMemoryShore Also, for each author's protection and ours, we want to make certain 44*2a48e470SMemoryShorethat everyone understands that there is no warranty for this free 45*2a48e470SMemoryShoresoftware. If the software is modified by someone else and passed on, we 46*2a48e470SMemoryShorewant its recipients to know that what they have is not the original, so 47*2a48e470SMemoryShorethat any problems introduced by others will not reflect on the original 48*2a48e470SMemoryShoreauthors' reputations. 49*2a48e470SMemoryShore 50*2a48e470SMemoryShore Finally, any free program is threatened constantly by software 51*2a48e470SMemoryShorepatents. We wish to avoid the danger that redistributors of a free 52*2a48e470SMemoryShoreprogram will individually obtain patent licenses, in effect making the 53*2a48e470SMemoryShoreprogram proprietary. To prevent this, we have made it clear that any 54*2a48e470SMemoryShorepatent must be licensed for everyone's free use or not licensed at all. 55*2a48e470SMemoryShore 56*2a48e470SMemoryShore The precise terms and conditions for copying, distribution and 57*2a48e470SMemoryShoremodification follow. 58*2a48e470SMemoryShore 59*2a48e470SMemoryShore GNU GENERAL PUBLIC LICENSE 60*2a48e470SMemoryShore TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*2a48e470SMemoryShore 62*2a48e470SMemoryShore 0. This License applies to any program or other work which contains 63*2a48e470SMemoryShorea notice placed by the copyright holder saying it may be distributed 64*2a48e470SMemoryShoreunder the terms of this General Public License. The "Program", below, 65*2a48e470SMemoryShorerefers to any such program or work, and a "work based on the Program" 66*2a48e470SMemoryShoremeans either the Program or any derivative work under copyright law: 67*2a48e470SMemoryShorethat is to say, a work containing the Program or a portion of it, 68*2a48e470SMemoryShoreeither verbatim or with modifications and/or translated into another 69*2a48e470SMemoryShorelanguage. (Hereinafter, translation is included without limitation in 70*2a48e470SMemoryShorethe term "modification".) Each licensee is addressed as "you". 71*2a48e470SMemoryShore 72*2a48e470SMemoryShoreActivities other than copying, distribution and modification are not 73*2a48e470SMemoryShorecovered by this License; they are outside its scope. The act of 74*2a48e470SMemoryShorerunning the Program is not restricted, and the output from the Program 75*2a48e470SMemoryShoreis covered only if its contents constitute a work based on the 76*2a48e470SMemoryShoreProgram (independent of having been made by running the Program). 77*2a48e470SMemoryShoreWhether that is true depends on what the Program does. 78*2a48e470SMemoryShore 79*2a48e470SMemoryShore 1. You may copy and distribute verbatim copies of the Program's 80*2a48e470SMemoryShoresource code as you receive it, in any medium, provided that you 81*2a48e470SMemoryShoreconspicuously and appropriately publish on each copy an appropriate 82*2a48e470SMemoryShorecopyright notice and disclaimer of warranty; keep intact all the 83*2a48e470SMemoryShorenotices that refer to this License and to the absence of any warranty; 84*2a48e470SMemoryShoreand give any other recipients of the Program a copy of this License 85*2a48e470SMemoryShorealong with the Program. 86*2a48e470SMemoryShore 87*2a48e470SMemoryShoreYou may charge a fee for the physical act of transferring a copy, and 88*2a48e470SMemoryShoreyou may at your option offer warranty protection in exchange for a fee. 89*2a48e470SMemoryShore 90*2a48e470SMemoryShore 2. You may modify your copy or copies of the Program or any portion 91*2a48e470SMemoryShoreof it, thus forming a work based on the Program, and copy and 92*2a48e470SMemoryShoredistribute such modifications or work under the terms of Section 1 93*2a48e470SMemoryShoreabove, provided that you also meet all of these conditions: 94*2a48e470SMemoryShore 95*2a48e470SMemoryShore a) You must cause the modified files to carry prominent notices 96*2a48e470SMemoryShore stating that you changed the files and the date of any change. 97*2a48e470SMemoryShore 98*2a48e470SMemoryShore b) You must cause any work that you distribute or publish, that in 99*2a48e470SMemoryShore whole or in part contains or is derived from the Program or any 100*2a48e470SMemoryShore part thereof, to be licensed as a whole at no charge to all third 101*2a48e470SMemoryShore parties under the terms of this License. 102*2a48e470SMemoryShore 103*2a48e470SMemoryShore c) If the modified program normally reads commands interactively 104*2a48e470SMemoryShore when run, you must cause it, when started running for such 105*2a48e470SMemoryShore interactive use in the most ordinary way, to print or display an 106*2a48e470SMemoryShore announcement including an appropriate copyright notice and a 107*2a48e470SMemoryShore notice that there is no warranty (or else, saying that you provide 108*2a48e470SMemoryShore a warranty) and that users may redistribute the program under 109*2a48e470SMemoryShore these conditions, and telling the user how to view a copy of this 110*2a48e470SMemoryShore License. (Exception: if the Program itself is interactive but 111*2a48e470SMemoryShore does not normally print such an announcement, your work based on 112*2a48e470SMemoryShore the Program is not required to print an announcement.) 113*2a48e470SMemoryShore 114*2a48e470SMemoryShoreThese requirements apply to the modified work as a whole. If 115*2a48e470SMemoryShoreidentifiable sections of that work are not derived from the Program, 116*2a48e470SMemoryShoreand can be reasonably considered independent and separate works in 117*2a48e470SMemoryShorethemselves, then this License, and its terms, do not apply to those 118*2a48e470SMemoryShoresections when you distribute them as separate works. But when you 119*2a48e470SMemoryShoredistribute the same sections as part of a whole which is a work based 120*2a48e470SMemoryShoreon the Program, the distribution of the whole must be on the terms of 121*2a48e470SMemoryShorethis License, whose permissions for other licensees extend to the 122*2a48e470SMemoryShoreentire whole, and thus to each and every part regardless of who wrote it. 123*2a48e470SMemoryShore 124*2a48e470SMemoryShoreThus, it is not the intent of this section to claim rights or contest 125*2a48e470SMemoryShoreyour rights to work written entirely by you; rather, the intent is to 126*2a48e470SMemoryShoreexercise the right to control the distribution of derivative or 127*2a48e470SMemoryShorecollective works based on the Program. 128*2a48e470SMemoryShore 129*2a48e470SMemoryShoreIn addition, mere aggregation of another work not based on the Program 130*2a48e470SMemoryShorewith the Program (or with a work based on the Program) on a volume of 131*2a48e470SMemoryShorea storage or distribution medium does not bring the other work under 132*2a48e470SMemoryShorethe scope of this License. 133*2a48e470SMemoryShore 134*2a48e470SMemoryShore 3. You may copy and distribute the Program (or a work based on it, 135*2a48e470SMemoryShoreunder Section 2) in object code or executable form under the terms of 136*2a48e470SMemoryShoreSections 1 and 2 above provided that you also do one of the following: 137*2a48e470SMemoryShore 138*2a48e470SMemoryShore a) Accompany it with the complete corresponding machine-readable 139*2a48e470SMemoryShore source code, which must be distributed under the terms of Sections 140*2a48e470SMemoryShore 1 and 2 above on a medium customarily used for software interchange; or, 141*2a48e470SMemoryShore 142*2a48e470SMemoryShore b) Accompany it with a written offer, valid for at least three 143*2a48e470SMemoryShore years, to give any third party, for a charge no more than your 144*2a48e470SMemoryShore cost of physically performing source distribution, a complete 145*2a48e470SMemoryShore machine-readable copy of the corresponding source code, to be 146*2a48e470SMemoryShore distributed under the terms of Sections 1 and 2 above on a medium 147*2a48e470SMemoryShore customarily used for software interchange; or, 148*2a48e470SMemoryShore 149*2a48e470SMemoryShore c) Accompany it with the information you received as to the offer 150*2a48e470SMemoryShore to distribute corresponding source code. (This alternative is 151*2a48e470SMemoryShore allowed only for noncommercial distribution and only if you 152*2a48e470SMemoryShore received the program in object code or executable form with such 153*2a48e470SMemoryShore an offer, in accord with Subsection b above.) 154*2a48e470SMemoryShore 155*2a48e470SMemoryShoreThe source code for a work means the preferred form of the work for 156*2a48e470SMemoryShoremaking modifications to it. For an executable work, complete source 157*2a48e470SMemoryShorecode means all the source code for all modules it contains, plus any 158*2a48e470SMemoryShoreassociated interface definition files, plus the scripts used to 159*2a48e470SMemoryShorecontrol compilation and installation of the executable. However, as a 160*2a48e470SMemoryShorespecial exception, the source code distributed need not include 161*2a48e470SMemoryShoreanything that is normally distributed (in either source or binary 162*2a48e470SMemoryShoreform) with the major components (compiler, kernel, and so on) of the 163*2a48e470SMemoryShoreoperating system on which the executable runs, unless that component 164*2a48e470SMemoryShoreitself accompanies the executable. 165*2a48e470SMemoryShore 166*2a48e470SMemoryShoreIf distribution of executable or object code is made by offering 167*2a48e470SMemoryShoreaccess to copy from a designated place, then offering equivalent 168*2a48e470SMemoryShoreaccess to copy the source code from the same place counts as 169*2a48e470SMemoryShoredistribution of the source code, even though third parties are not 170*2a48e470SMemoryShorecompelled to copy the source along with the object code. 171*2a48e470SMemoryShore 172*2a48e470SMemoryShore 4. You may not copy, modify, sublicense, or distribute the Program 173*2a48e470SMemoryShoreexcept as expressly provided under this License. Any attempt 174*2a48e470SMemoryShoreotherwise to copy, modify, sublicense or distribute the Program is 175*2a48e470SMemoryShorevoid, and will automatically terminate your rights under this License. 176*2a48e470SMemoryShoreHowever, parties who have received copies, or rights, from you under 177*2a48e470SMemoryShorethis License will not have their licenses terminated so long as such 178*2a48e470SMemoryShoreparties remain in full compliance. 179*2a48e470SMemoryShore 180*2a48e470SMemoryShore 5. You are not required to accept this License, since you have not 181*2a48e470SMemoryShoresigned it. However, nothing else grants you permission to modify or 182*2a48e470SMemoryShoredistribute the Program or its derivative works. These actions are 183*2a48e470SMemoryShoreprohibited by law if you do not accept this License. Therefore, by 184*2a48e470SMemoryShoremodifying or distributing the Program (or any work based on the 185*2a48e470SMemoryShoreProgram), you indicate your acceptance of this License to do so, and 186*2a48e470SMemoryShoreall its terms and conditions for copying, distributing or modifying 187*2a48e470SMemoryShorethe Program or works based on it. 188*2a48e470SMemoryShore 189*2a48e470SMemoryShore 6. Each time you redistribute the Program (or any work based on the 190*2a48e470SMemoryShoreProgram), the recipient automatically receives a license from the 191*2a48e470SMemoryShoreoriginal licensor to copy, distribute or modify the Program subject to 192*2a48e470SMemoryShorethese terms and conditions. You may not impose any further 193*2a48e470SMemoryShorerestrictions on the recipients' exercise of the rights granted herein. 194*2a48e470SMemoryShoreYou are not responsible for enforcing compliance by third parties to 195*2a48e470SMemoryShorethis License. 196*2a48e470SMemoryShore 197*2a48e470SMemoryShore 7. If, as a consequence of a court judgment or allegation of patent 198*2a48e470SMemoryShoreinfringement or for any other reason (not limited to patent issues), 199*2a48e470SMemoryShoreconditions are imposed on you (whether by court order, agreement or 200*2a48e470SMemoryShoreotherwise) that contradict the conditions of this License, they do not 201*2a48e470SMemoryShoreexcuse you from the conditions of this License. If you cannot 202*2a48e470SMemoryShoredistribute so as to satisfy simultaneously your obligations under this 203*2a48e470SMemoryShoreLicense and any other pertinent obligations, then as a consequence you 204*2a48e470SMemoryShoremay not distribute the Program at all. For example, if a patent 205*2a48e470SMemoryShorelicense would not permit royalty-free redistribution of the Program by 206*2a48e470SMemoryShoreall those who receive copies directly or indirectly through you, then 207*2a48e470SMemoryShorethe only way you could satisfy both it and this License would be to 208*2a48e470SMemoryShorerefrain entirely from distribution of the Program. 209*2a48e470SMemoryShore 210*2a48e470SMemoryShoreIf any portion of this section is held invalid or unenforceable under 211*2a48e470SMemoryShoreany particular circumstance, the balance of the section is intended to 212*2a48e470SMemoryShoreapply and the section as a whole is intended to apply in other 213*2a48e470SMemoryShorecircumstances. 214*2a48e470SMemoryShore 215*2a48e470SMemoryShoreIt is not the purpose of this section to induce you to infringe any 216*2a48e470SMemoryShorepatents or other property right claims or to contest validity of any 217*2a48e470SMemoryShoresuch claims; this section has the sole purpose of protecting the 218*2a48e470SMemoryShoreintegrity of the free software distribution system, which is 219*2a48e470SMemoryShoreimplemented by public license practices. Many people have made 220*2a48e470SMemoryShoregenerous contributions to the wide range of software distributed 221*2a48e470SMemoryShorethrough that system in reliance on consistent application of that 222*2a48e470SMemoryShoresystem; it is up to the author/donor to decide if he or she is willing 223*2a48e470SMemoryShoreto distribute software through any other system and a licensee cannot 224*2a48e470SMemoryShoreimpose that choice. 225*2a48e470SMemoryShore 226*2a48e470SMemoryShoreThis section is intended to make thoroughly clear what is believed to 227*2a48e470SMemoryShorebe a consequence of the rest of this License. 228*2a48e470SMemoryShore 229*2a48e470SMemoryShore 8. If the distribution and/or use of the Program is restricted in 230*2a48e470SMemoryShorecertain countries either by patents or by copyrighted interfaces, the 231*2a48e470SMemoryShoreoriginal copyright holder who places the Program under this License 232*2a48e470SMemoryShoremay add an explicit geographical distribution limitation excluding 233*2a48e470SMemoryShorethose countries, so that distribution is permitted only in or among 234*2a48e470SMemoryShorecountries not thus excluded. In such case, this License incorporates 235*2a48e470SMemoryShorethe limitation as if written in the body of this License. 236*2a48e470SMemoryShore 237*2a48e470SMemoryShore 9. The Free Software Foundation may publish revised and/or new versions 238*2a48e470SMemoryShoreof the General Public License from time to time. Such new versions will 239*2a48e470SMemoryShorebe similar in spirit to the present version, but may differ in detail to 240*2a48e470SMemoryShoreaddress new problems or concerns. 241*2a48e470SMemoryShore 242*2a48e470SMemoryShoreEach version is given a distinguishing version number. If the Program 243*2a48e470SMemoryShorespecifies a version number of this License which applies to it and "any 244*2a48e470SMemoryShorelater version", you have the option of following the terms and conditions 245*2a48e470SMemoryShoreeither of that version or of any later version published by the Free 246*2a48e470SMemoryShoreSoftware Foundation. If the Program does not specify a version number of 247*2a48e470SMemoryShorethis License, you may choose any version ever published by the Free Software 248*2a48e470SMemoryShoreFoundation. 249*2a48e470SMemoryShore 250*2a48e470SMemoryShore 10. If you wish to incorporate parts of the Program into other free 251*2a48e470SMemoryShoreprograms whose distribution conditions are different, write to the author 252*2a48e470SMemoryShoreto ask for permission. For software which is copyrighted by the Free 253*2a48e470SMemoryShoreSoftware Foundation, write to the Free Software Foundation; we sometimes 254*2a48e470SMemoryShoremake exceptions for this. Our decision will be guided by the two goals 255*2a48e470SMemoryShoreof preserving the free status of all derivatives of our free software and 256*2a48e470SMemoryShoreof promoting the sharing and reuse of software generally. 257*2a48e470SMemoryShore 258*2a48e470SMemoryShore NO WARRANTY 259*2a48e470SMemoryShore 260*2a48e470SMemoryShore 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*2a48e470SMemoryShoreFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*2a48e470SMemoryShoreOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*2a48e470SMemoryShorePROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*2a48e470SMemoryShoreOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*2a48e470SMemoryShoreMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*2a48e470SMemoryShoreTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267*2a48e470SMemoryShorePROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268*2a48e470SMemoryShoreREPAIR OR CORRECTION. 269*2a48e470SMemoryShore 270*2a48e470SMemoryShore 12.
