By contrast, the GNU General Public 13*508ec739SDaniel RosenbergLicense is intended to guarantee your freedom to share and change free 14*508ec739SDaniel Rosenbergsoftware--to make sure the software is free for all its users. This 15*508ec739SDaniel RosenbergGeneral Public License applies to most of the Free Software 16*508ec739SDaniel RosenbergFoundation's software and to any other program whose authors commit to 17*508ec739SDaniel Rosenbergusing it. (Some other Free Software Foundation software is covered by 18*508ec739SDaniel Rosenbergthe GNU Lesser General Public License instead.) You can apply it to 19*508ec739SDaniel Rosenbergyour programs, too. 20*508ec739SDaniel Rosenberg 21*508ec739SDaniel Rosenberg When we speak of free software, we are referring to freedom, not 22*508ec739SDaniel Rosenbergprice. Our General Public Licenses are designed to make sure that you 23*508ec739SDaniel Rosenberghave the freedom to distribute copies of free software (and charge for 24*508ec739SDaniel Rosenbergthis service if you wish), that you receive source code or can get it 25*508ec739SDaniel Rosenbergif you want it, that you can change the software or use pieces of it 26*508ec739SDaniel Rosenbergin new free programs; and that you know you can do these things. 27*508ec739SDaniel Rosenberg 28*508ec739SDaniel Rosenberg To protect your rights, we need to make restrictions that forbid 29*508ec739SDaniel Rosenberganyone to deny you these rights or to ask you to surrender the rights. 30*508ec739SDaniel RosenbergThese restrictions translate to certain responsibilities for you if you 31*508ec739SDaniel Rosenbergdistribute copies of the software, or if you modify it. 32*508ec739SDaniel Rosenberg 33*508ec739SDaniel Rosenberg For example, if you distribute copies of such a program, whether 34*508ec739SDaniel Rosenberggratis or for a fee, you must give the recipients all the rights that 35*508ec739SDaniel Rosenbergyou have. You must make sure that they, too, receive or can get the 36*508ec739SDaniel Rosenbergsource code. And you must show them these terms so they know their 37*508ec739SDaniel Rosenbergrights. 38*508ec739SDaniel Rosenberg 39*508ec739SDaniel Rosenberg We protect your rights with two steps: (1) copyright the software, and 40*508ec739SDaniel Rosenberg(2) offer you this license which gives you legal permission to copy, 41*508ec739SDaniel Rosenbergdistribute and/or modify the software. 42*508ec739SDaniel Rosenberg 43*508ec739SDaniel Rosenberg Also, for each author's protection and ours, we want to make certain 44*508ec739SDaniel Rosenbergthat everyone understands that there is no warranty for this free 45*508ec739SDaniel Rosenbergsoftware. If the software is modified by someone else and passed on, we 46*508ec739SDaniel Rosenbergwant its recipients to know that what they have is not the original, so 47*508ec739SDaniel Rosenbergthat any problems introduced by others will not reflect on the original 48*508ec739SDaniel Rosenbergauthors' reputations. 49*508ec739SDaniel Rosenberg 50*508ec739SDaniel Rosenberg Finally, any free program is threatened constantly by software 51*508ec739SDaniel Rosenbergpatents. We wish to avoid the danger that redistributors of a free 52*508ec739SDaniel Rosenbergprogram will individually obtain patent licenses, in effect making the 53*508ec739SDaniel Rosenbergprogram proprietary. To prevent this, we have made it clear that any 54*508ec739SDaniel Rosenbergpatent must be licensed for everyone's free use or not licensed at all. 55*508ec739SDaniel Rosenberg 56*508ec739SDaniel Rosenberg The precise terms and conditions for copying, distribution and 57*508ec739SDaniel Rosenbergmodification follow. 58*508ec739SDaniel Rosenberg 59*508ec739SDaniel Rosenberg GNU GENERAL PUBLIC LICENSE 60*508ec739SDaniel Rosenberg TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*508ec739SDaniel Rosenberg 62*508ec739SDaniel Rosenberg 0. This License applies to any program or other work which contains 63*508ec739SDaniel Rosenberga notice placed by the copyright holder saying it may be distributed 64*508ec739SDaniel Rosenbergunder the terms of this General Public License. The "Program", below, 65*508ec739SDaniel Rosenbergrefers to any such program or work, and a "work based on the Program" 66*508ec739SDaniel Rosenbergmeans either the Program or any derivative work under copyright law: 67*508ec739SDaniel Rosenbergthat is to say, a work containing the Program or a portion of it, 68*508ec739SDaniel Rosenbergeither verbatim or with modifications and/or translated into another 69*508ec739SDaniel Rosenberglanguage. (Hereinafter, translation is included without limitation in 70*508ec739SDaniel Rosenbergthe term "modification".) Each licensee is addressed as "you". 71*508ec739SDaniel Rosenberg 72*508ec739SDaniel RosenbergActivities other than copying, distribution and modification are not 73*508ec739SDaniel Rosenbergcovered by this License; they are outside its scope. The act of 74*508ec739SDaniel Rosenbergrunning the Program is not restricted, and the output from the Program 75*508ec739SDaniel Rosenbergis covered only if its contents constitute a work based on the 76*508ec739SDaniel RosenbergProgram (independent of having been made by running the Program). 77*508ec739SDaniel RosenbergWhether that is true depends on what the Program does. 78*508ec739SDaniel Rosenberg 79*508ec739SDaniel Rosenberg 1. You may copy and distribute verbatim copies of the Program's 80*508ec739SDaniel Rosenbergsource code as you receive it, in any medium, provided that you 81*508ec739SDaniel Rosenbergconspicuously and appropriately publish on each copy an appropriate 82*508ec739SDaniel Rosenbergcopyright notice and disclaimer of warranty; keep intact all the 83*508ec739SDaniel Rosenbergnotices that refer to this License and to the absence of any warranty; 84*508ec739SDaniel Rosenbergand give any other recipients of the Program a copy of this License 85*508ec739SDaniel Rosenbergalong with the Program. 86*508ec739SDaniel Rosenberg 87*508ec739SDaniel RosenbergYou may charge a fee for the physical act of transferring a copy, and 88*508ec739SDaniel Rosenbergyou may at your option offer warranty protection in exchange for a fee. 89*508ec739SDaniel Rosenberg 90*508ec739SDaniel Rosenberg 2. You may modify your copy or copies of the Program or any portion 91*508ec739SDaniel Rosenbergof it, thus forming a work based on the Program, and copy and 92*508ec739SDaniel Rosenbergdistribute such modifications or work under the terms of Section 1 93*508ec739SDaniel Rosenbergabove, provided that you also meet all of these conditions: 94*508ec739SDaniel Rosenberg 95*508ec739SDaniel Rosenberg a) You must cause the modified files to carry prominent notices 96*508ec739SDaniel Rosenberg stating that you changed the files and the date of any change. 97*508ec739SDaniel Rosenberg 98*508ec739SDaniel Rosenberg b) You must cause any work that you distribute or publish, that in 99*508ec739SDaniel Rosenberg whole or in part contains or is derived from the Program or any 100*508ec739SDaniel Rosenberg part thereof, to be licensed as a whole at no charge to all third 101*508ec739SDaniel Rosenberg parties under the terms of this License. 102*508ec739SDaniel Rosenberg 103*508ec739SDaniel Rosenberg c) If the modified program normally reads commands interactively 104*508ec739SDaniel Rosenberg when run, you must cause it, when started running for such 105*508ec739SDaniel Rosenberg interactive use in the most ordinary way, to print or display an 106*508ec739SDaniel Rosenberg announcement including an appropriate copyright notice and a 107*508ec739SDaniel Rosenberg notice that there is no warranty (or else, saying that you provide 108*508ec739SDaniel Rosenberg a warranty) and that users may redistribute the program under 109*508ec739SDaniel Rosenberg these conditions, and telling the user how to view a copy of this 110*508ec739SDaniel Rosenberg License. (Exception: if the Program itself is interactive but 111*508ec739SDaniel Rosenberg does not normally print such an announcement, your work based on 112*508ec739SDaniel Rosenberg the Program is not required to print an announcement.) 113*508ec739SDaniel Rosenberg 114*508ec739SDaniel RosenbergThese requirements apply to the modified work as a whole. If 115*508ec739SDaniel Rosenbergidentifiable sections of that work are not derived from the Program, 116*508ec739SDaniel Rosenbergand can be reasonably considered independent and separate works in 117*508ec739SDaniel Rosenbergthemselves, then this License, and its terms, do not apply to those 118*508ec739SDaniel Rosenbergsections when you distribute them as separate works. But when you 119*508ec739SDaniel Rosenbergdistribute the same sections as part of a whole which is a work based 120*508ec739SDaniel Rosenbergon the Program, the distribution of the whole must be on the terms of 121*508ec739SDaniel Rosenbergthis License, whose permissions for other licensees extend to the 122*508ec739SDaniel Rosenbergentire whole, and thus to each and every part regardless of who wrote it. 123*508ec739SDaniel Rosenberg 124*508ec739SDaniel RosenbergThus, it is not the intent of this section to claim rights or contest 125*508ec739SDaniel Rosenbergyour rights to work written entirely by you; rather, the intent is to 126*508ec739SDaniel Rosenbergexercise the right to control the distribution of derivative or 127*508ec739SDaniel Rosenbergcollective works based on the Program. 128*508ec739SDaniel Rosenberg 129*508ec739SDaniel RosenbergIn addition, mere aggregation of another work not based on the Program 130*508ec739SDaniel Rosenbergwith the Program (or with a work based on the Program) on a volume of 131*508ec739SDaniel Rosenberga storage or distribution medium does not bring the other work under 132*508ec739SDaniel Rosenbergthe scope of this License. 133*508ec739SDaniel Rosenberg 134*508ec739SDaniel Rosenberg 3. You may copy and distribute the Program (or a work based on it, 135*508ec739SDaniel Rosenbergunder Section 2) in object code or executable form under the terms of 136*508ec739SDaniel RosenbergSections 1 and 2 above provided that you also do one of the following: 137*508ec739SDaniel Rosenberg 138*508ec739SDaniel Rosenberg a) Accompany it with the complete corresponding machine-readable 139*508ec739SDaniel Rosenberg source code, which must be distributed under the terms of Sections 140*508ec739SDaniel Rosenberg 1 and 2 above on a medium customarily used for software interchange; or, 141*508ec739SDaniel Rosenberg 142*508ec739SDaniel Rosenberg b) Accompany it with a written offer, valid for at least three 143*508ec739SDaniel Rosenberg years, to give any third party, for a charge no more than your 144*508ec739SDaniel Rosenberg cost of physically performing source distribution, a complete 145*508ec739SDaniel Rosenberg machine-readable copy of the corresponding source code, to be 146*508ec739SDaniel Rosenberg distributed under the terms of Sections 1 and 2 above on a medium 147*508ec739SDaniel Rosenberg customarily used for software interchange; or, 148*508ec739SDaniel Rosenberg 149*508ec739SDaniel Rosenberg c) Accompany it with the information you received as to the offer 150*508ec739SDaniel Rosenberg to distribute corresponding source code. (This alternative is 151*508ec739SDaniel Rosenberg allowed only for noncommercial distribution and only if you 152*508ec739SDaniel Rosenberg received the program in object code or executable form with such 153*508ec739SDaniel Rosenberg an offer, in accord with Subsection b above.) 154*508ec739SDaniel Rosenberg 155*508ec739SDaniel RosenbergThe source code for a work means the preferred form of the work for 156*508ec739SDaniel Rosenbergmaking modifications to it. For an executable work, complete source 157*508ec739SDaniel Rosenbergcode means all the source code for all modules it contains, plus any 158*508ec739SDaniel Rosenbergassociated interface definition files, plus the scripts used to 159*508ec739SDaniel Rosenbergcontrol compilation and installation of the executable. However, as a 160*508ec739SDaniel Rosenbergspecial exception, the source code distributed need not include 161*508ec739SDaniel Rosenberganything that is normally distributed (in either source or binary 162*508ec739SDaniel Rosenbergform) with the major components (compiler, kernel, and so on) of the 163*508ec739SDaniel Rosenbergoperating system on which the executable runs, unless that component 164*508ec739SDaniel Rosenbergitself accompanies the executable. 165*508ec739SDaniel Rosenberg 166*508ec739SDaniel RosenbergIf distribution of executable or object code is made by offering 167*508ec739SDaniel Rosenbergaccess to copy from a designated place, then offering equivalent 168*508ec739SDaniel Rosenbergaccess to copy the source code from the same place counts as 169*508ec739SDaniel Rosenbergdistribution of the source code, even though third parties are not 170*508ec739SDaniel Rosenbergcompelled to copy the source along with the object code. 171*508ec739SDaniel Rosenberg 172*508ec739SDaniel Rosenberg 4. You may not copy, modify, sublicense, or distribute the Program 173*508ec739SDaniel Rosenbergexcept as expressly provided under this License. Any attempt 174*508ec739SDaniel Rosenbergotherwise to copy, modify, sublicense or distribute the Program is 175*508ec739SDaniel Rosenbergvoid, and will automatically terminate your rights under this License. 176*508ec739SDaniel RosenbergHowever, parties who have received copies, or rights, from you under 177*508ec739SDaniel Rosenbergthis License will not have their licenses terminated so long as such 178*508ec739SDaniel Rosenbergparties remain in full compliance. 179*508ec739SDaniel Rosenberg 180*508ec739SDaniel Rosenberg 5. You are not required to accept this License, since you have not 181*508ec739SDaniel Rosenbergsigned it. However, nothing else grants you permission to modify or 182*508ec739SDaniel Rosenbergdistribute the Program or its derivative works. These actions are 183*508ec739SDaniel Rosenbergprohibited by law if you do not accept this License. Therefore, by 184*508ec739SDaniel Rosenbergmodifying or distributing the Program (or any work based on the 185*508ec739SDaniel RosenbergProgram), you indicate your acceptance of this License to do so, and 186*508ec739SDaniel Rosenbergall its terms and conditions for copying, distributing or modifying 187*508ec739SDaniel Rosenbergthe Program or works based on it. 188*508ec739SDaniel Rosenberg 189*508ec739SDaniel Rosenberg 6. Each time you redistribute the Program (or any work based on the 190*508ec739SDaniel RosenbergProgram), the recipient automatically receives a license from the 191*508ec739SDaniel Rosenbergoriginal licensor to copy, distribute or modify the Program subject to 192*508ec739SDaniel Rosenbergthese terms and conditions. You may not impose any further 193*508ec739SDaniel Rosenbergrestrictions on the recipients' exercise of the rights granted herein. 194*508ec739SDaniel RosenbergYou are not responsible for enforcing compliance by third parties to 195*508ec739SDaniel Rosenbergthis License. 196*508ec739SDaniel Rosenberg 197*508ec739SDaniel Rosenberg 7. If, as a consequence of a court judgment or allegation of patent 198*508ec739SDaniel Rosenberginfringement or for any other reason (not limited to patent issues), 199*508ec739SDaniel Rosenbergconditions are imposed on you (whether by court order, agreement or 200*508ec739SDaniel Rosenbergotherwise) that contradict the conditions of this License, they do not 201*508ec739SDaniel Rosenbergexcuse you from the conditions of this License. If you cannot 202*508ec739SDaniel Rosenbergdistribute so as to satisfy simultaneously your obligations under this 203*508ec739SDaniel RosenbergLicense and any other pertinent obligations, then as a consequence you 204*508ec739SDaniel Rosenbergmay not distribute the Program at all. For example, if a patent 205*508ec739SDaniel Rosenberglicense would not permit royalty-free redistribution of the Program by 206*508ec739SDaniel Rosenbergall those who receive copies directly or indirectly through you, then 207*508ec739SDaniel Rosenbergthe only way you could satisfy both it and this License would be to 208*508ec739SDaniel Rosenbergrefrain entirely from distribution of the Program. 209*508ec739SDaniel Rosenberg 210*508ec739SDaniel RosenbergIf any portion of this section is held invalid or unenforceable under 211*508ec739SDaniel Rosenbergany particular circumstance, the balance of the section is intended to 212*508ec739SDaniel Rosenbergapply and the section as a whole is intended to apply in other 213*508ec739SDaniel Rosenbergcircumstances. 214*508ec739SDaniel Rosenberg 215*508ec739SDaniel RosenbergIt is not the purpose of this section to induce you to infringe any 216*508ec739SDaniel Rosenbergpatents or other property right claims or to contest validity of any 217*508ec739SDaniel Rosenbergsuch claims; this section has the sole purpose of protecting the 218*508ec739SDaniel Rosenbergintegrity of the free software distribution system, which is 219*508ec739SDaniel Rosenbergimplemented by public license practices. Many people have made 220*508ec739SDaniel Rosenberggenerous contributions to the wide range of software distributed 221*508ec739SDaniel Rosenbergthrough that system in reliance on consistent application of that 222*508ec739SDaniel Rosenbergsystem; it is up to the author/donor to decide if he or she is willing 223*508ec739SDaniel Rosenbergto distribute software through any other system and a licensee cannot 224*508ec739SDaniel Rosenbergimpose that choice. 225*508ec739SDaniel Rosenberg 226*508ec739SDaniel RosenbergThis section is intended to make thoroughly clear what is believed to 227*508ec739SDaniel Rosenbergbe a consequence of the rest of this License. 228*508ec739SDaniel Rosenberg 229*508ec739SDaniel Rosenberg 8. If the distribution and/or use of the Program is restricted in 230*508ec739SDaniel Rosenbergcertain countries either by patents or by copyrighted interfaces, the 231*508ec739SDaniel Rosenbergoriginal copyright holder who places the Program under this License 232*508ec739SDaniel Rosenbergmay add an explicit geographical distribution limitation excluding 233*508ec739SDaniel Rosenbergthose countries, so that distribution is permitted only in or among 234*508ec739SDaniel Rosenbergcountries not thus excluded. In such case, this License incorporates 235*508ec739SDaniel Rosenbergthe limitation as if written in the body of this License. 236*508ec739SDaniel Rosenberg 237*508ec739SDaniel Rosenberg 9. The Free Software Foundation may publish revised and/or new versions 238*508ec739SDaniel Rosenbergof the General Public License from time to time. Such new versions will 239*508ec739SDaniel Rosenbergbe similar in spirit to the present version, but may differ in detail to 240*508ec739SDaniel Rosenbergaddress new problems or concerns. 241*508ec739SDaniel Rosenberg 242*508ec739SDaniel RosenbergEach version is given a distinguishing version number. If the Program 243*508ec739SDaniel Rosenbergspecifies a version number of this License which applies to it and "any 244*508ec739SDaniel Rosenberglater version", you have the option of following the terms and conditions 245*508ec739SDaniel Rosenbergeither of that version or of any later version published by the Free 246*508ec739SDaniel RosenbergSoftware Foundation. If the Program does not specify a version number of 247*508ec739SDaniel Rosenbergthis License, you may choose any version ever published by the Free Software 248*508ec739SDaniel RosenbergFoundation. 249*508ec739SDaniel Rosenberg 250*508ec739SDaniel Rosenberg 10. If you wish to incorporate parts of the Program into other free 251*508ec739SDaniel Rosenbergprograms whose distribution conditions are different, write to the author 252*508ec739SDaniel Rosenbergto ask for permission. For software which is copyrighted by the Free 253*508ec739SDaniel RosenbergSoftware Foundation, write to the Free Software Foundation; we sometimes 254*508ec739SDaniel Rosenbergmake exceptions for this. Our decision will be guided by the two goals 255*508ec739SDaniel Rosenbergof preserving the free status of all derivatives of our free software and 256*508ec739SDaniel Rosenbergof promoting the sharing and reuse of software generally. 257*508ec739SDaniel Rosenberg 258*508ec739SDaniel Rosenberg NO WARRANTY 259*508ec739SDaniel Rosenberg 260*508ec739SDaniel Rosenberg 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*508ec739SDaniel RosenbergFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*508ec739SDaniel RosenbergOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*508ec739SDaniel RosenbergPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*508ec739SDaniel RosenbergOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*508ec739SDaniel RosenbergMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*508ec739SDaniel RosenbergTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267*508ec739SDaniel RosenbergPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268*508ec739SDaniel RosenbergREPAIR OR CORRECTION. 269*508ec739SDaniel Rosenberg 270*508ec739SDaniel Rosenberg 12.
