By\ 18 contrast, the GNU General Public License is intended to guarantee your freedom to share and change free\ 19 software--to make sure the software is free for all its users. This General Public License applies to most of\ 20 the Free Software Foundation's software and to any other program whose authors commit to using it.\ 21 (Some other Free Software Foundation software is covered by the GNU Library General Public License\ 22 instead.) You can apply it to your programs, too.\ 23\ 24 When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are\ 25 designed to make sure that you have the freedom to distribute copies of free software (and charge for this\ 26 service if you wish), that you receive source code or can get it if you want it, that you can change the\ 27 software or use pieces of it in new free programs; and that you know you can do these things.\ 28\ 29 To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask\ 30 you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute\ 31 copies of the software, or if you modify it.\ 32\ 33 For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the\ 34 recipients all the rights that you have. You must make sure that they, too, receive or can get the source\ 35 code. And you must show them these terms so they know their rights.\ 36\ 37 We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives\ 38 you legal permission to copy, distribute and/or modify the software.\ 39\ 40 Also, for each author's protection and ours, we want to make certain that everyone understands that there\ 41 is no warranty for this free software. If the software is modified by someone else and passed on, we want\ 42 its recipients to know that what they have is not the original, so that any problems introduced by others will\ 43 not reflect on the original authors' reputations.\ 44\ 45 Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that\ 46 redistributors of a free program will individually obtain patent licenses, in effect making the program\ 47 proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use\ 48 or not licensed at all.\ 49\ 50 The precise terms and conditions for copying, distribution and modification follow.\ 51\ 52 GNU GENERAL PUBLIC LICENSE\ 53 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\ 54\ 55 0. This License applies to any program or other work which contains a notice placed by the copyright\ 56 holder saying it may be distributed under the terms of this General Public License. The "Program", below,\ 57 refers to any such program or work, and a "work based on the Program" means either the Program or any\ 58 derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either\ 59 verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included\ 60 without limitation in the term "modification".) Each licensee is addressed as "you".\ 61\ 62 Activities other than copying, distribution and modification are not covered by this License; they are outside\ 63 its scope. The act of running the Program is not restricted, and the output from the Program is covered\ 64 only if its contents constitute a work based on the Program (independent of having been made by running\ 65 the Program). Whether that is true depends on what the Program does.\ 66\ 67 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any\ 68 medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright\ 69 notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence\ 70 of any warranty; and give any other recipients of the Program a copy of this License along with the\ 71 Program.\ 72\ 73 You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty\ 74 protection in exchange for a fee.\ 75\ 76 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on\ 77 the Program, and copy and distribute such modifications or work under the terms of Section 1 above,\ 78 provided that you also meet all of these conditions:\ 79\ 80 a) You must cause the modified files to carry prominent notices stating that you changed the files and the\ 81 date of any change.\ 82\ 83 b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived\ 84 from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the\ 85 terms of this License.\ 86\ 87 c) If the modified program normally reads commands interactively when run, you must cause it, when\ 88 started running for such interactive use in the most ordinary way, to print or display an announcement\ 89 including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you\ 90 provide a warranty) and that users may redistribute the program under these conditions, and telling the\ 91 user how to view a copy of this License. (Exception: if the Program itself is interactive but does not\ 92 normally print such an announcement, your work based on the Program is not required to print an\ 93 announcement.)\ 94\ 95 These requirements apply to the modified work as a whole. If identifiable sections of that work are not\ 96 derived from the Program, and can be reasonably considered independent and separate works in\ 97 themselves, then this License, and its terms, do not apply to those sections when you distribute them as\ 98 separate works. But when you distribute the same sections as part of a whole which is a work based on\ 99 the Program, the distribution of the whole must be on the terms of this License, whose permissions for\ 100 other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.\ 101\ 102 Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you;\ 103 rather, the intent is to exercise the right to control the distribution of derivative or collective works based on\ 104 the Program.\ 105\ 106 In addition, mere aggregation of another work not based on the Program with the Program (or with a work\ 107 based on the Program) on a volume of a storage or distribution medium does not bring the other work under\ 108 the scope of this License.\ 109\ 110 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or\ 111 executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:\ 112\ 113 a) Accompany it with the complete corresponding machine-readable source code, which must be\ 114 distributed under the terms of Sections 1 and 2 above on a medium customarily used for software\ 115 interchange; or,\ 116\ 117 b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no\ 118 more than your cost of physically performing source distribution, a complete machine-readable copy of the\ 119 corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium\ 120 customarily used for software interchange; or,\ 121\ 122 c) Accompany it with the information you received as to the offer to distribute corresponding source code.\ 123 (This alternative is allowed only for noncommercial distribution and only if you received the program in\ 124 object code or executable form with such an offer, in accord with Subsection b above.)\ 125\ 126 The source code for a work means the preferred form of the work for making modifications to it. For an\ 127 executable work, complete source code means all the source code for all modules it contains, plus any\ 128 associated interface definition files, plus the scripts used to control compilation and installation of the\ 129 executable. However, as a special exception, the source code distributed need not include anything that is\ 130 normally distributed (in either source or binary form) with the major components (compiler, kernel, and so\ 131 on) of the operating system on which the executable runs, unless that component itself accompanies the\ 132 executable.\ 133\ 134 If distribution of executable or object code is made by offering access to copy from a designated place,\ 135 then offering equivalent access to copy the source code from the same place counts as distribution of the\ 136 source code, even though third parties are not compelled to copy the source along with the object code.\ 137\ 138 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under\ 139 this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will\ 140 automatically terminate your rights under this License. However, parties who have received copies, or\ 141 rights, from you under this License will not have their licenses terminated so long as such parties remain in\ 142 full compliance.\ 143\ 144 5. You are not required to accept this License, since you have not signed it. However, nothing else grants\ 145 you permission to modify or distribute the Program or its derivative works. These actions are prohibited by\ 146 law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work\ 147 based on the Program), you indicate your acceptance of this License to do so, and all its terms and\ 148 conditions for copying, distributing or modifying the Program or works based on it.\ 149\ 150 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically\ 151 receives a license from the original licensor to copy, distribute or modify the Program subject to these\ 152 terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights\ 153 granted herein. You are not responsible for enforcing compliance by third parties to this License.\ 154\ 155 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not\ 156 limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise)\ 157 that contradict the conditions of this License, they do not excuse you from the conditions of this License. If\ 158 you cannot distribute so as to satisfy simultaneously your obligations under this License and any other\ 159 pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a\ 160 patent license would not permit royalty-free redistribution of the Program by all those who receive copies\ 161 directly or indirectly through you, then the only way you could satisfy both it and this License would be to\ 162 refrain entirely from distribution of the Program.\ 163\ 164 If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance\ 165 of the section is intended to apply and the section as a whole is intended to apply in other circumstances.\ 166\ 167 It is not the purpose of this section to induce you to infringe any patents or other property right claims or to\ 168 contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free\ 169 software distribution system, which is implemented by public license practices. Many people have made\ 170 generous contributions to the wide range of software distributed through that system in reliance on\ 171 consistent application of that system; it is up to the author/donor to decide if he or she is willing to\ 172 distribute software through any other system and a licensee cannot impose that choice.\ 173\ 174 This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this\ 175 License.\ 176\ 177 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by\ 178 copyrighted interfaces, the original copyright holder who places the Program under this License may add\ 179 an explicit geographical distribution limitation excluding those countries, so that distribution is permitted\ 180 only in or among countries not thus excluded. In such case, this License incorporates the limitation as if\ 181 written in the body of this License.\ 182\ 183 9. The Free Software Foundation may publish revised and/or new versions of the General Public License\ 184 from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail\ 185 to address new problems or concerns.\ 186\ 187 Each version is given a distinguishing version number. If the Program specifies a version number of this\ 188 License which applies to it and "any later version", you have the option of following the terms and\ 189 conditions either of that version or of any later version published by the Free Software Foundation. If the\ 190 Program does not specify a version number of this License, you may choose any version ever published by\ 191 the Free Software Foundation.\ 192\ 193 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions\ 194 are different, write to the author to ask for permission. For software which is copyrighted by the Free\ 195 Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our\ 196 decision will be guided by the two goals of preserving the free status of all derivatives of our free software\ 197 and of promoting the sharing and reuse of software generally.\ 198\ 199 NO WARRANTY\ 200\ 201 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE\ 202 PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE\ 203 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE\ 204 PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,\ 205 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS\ 206 FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF\ 207 THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE\ 208 COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\ 209\ 210 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY\ 211 COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE\ 212 PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\ 213 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR\ 214 INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA\ 215 BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A\ 216 FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH\ 217 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.\ 218\ 219 END OF TERMS AND CONDITIONS\ 220}
