18d6344f9Sopenharmony_ci GNU GENERAL PUBLIC LICENSE 28d6344f9Sopenharmony_ci Version 2, June 1991 38d6344f9Sopenharmony_ci 48d6344f9Sopenharmony_ci Copyright (C) 1989, 1991 Free Software Foundation, Inc. 58d6344f9Sopenharmony_ci 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 68d6344f9Sopenharmony_ci Everyone is permitted to copy and distribute verbatim copies 78d6344f9Sopenharmony_ci of this license document, but changing it is not allowed. 88d6344f9Sopenharmony_ci 98d6344f9Sopenharmony_ci Preamble 108d6344f9Sopenharmony_ci 118d6344f9Sopenharmony_ci The licenses for most software are designed to take away your 128d6344f9Sopenharmony_cifreedom to share and change it. By contrast, the GNU General Public 138d6344f9Sopenharmony_ciLicense is intended to guarantee your freedom to share and change free 148d6344f9Sopenharmony_cisoftware--to make sure the software is free for all its users. This 158d6344f9Sopenharmony_ciGeneral Public License applies to most of the Free Software 168d6344f9Sopenharmony_ciFoundation's software and to any other program whose authors commit to 178d6344f9Sopenharmony_ciusing it. (Some other Free Software Foundation software is covered by 188d6344f9Sopenharmony_cithe GNU Library General Public License instead.) You can apply it to 198d6344f9Sopenharmony_ciyour programs, too. 208d6344f9Sopenharmony_ci 218d6344f9Sopenharmony_ci When we speak of free software, we are referring to freedom, not 228d6344f9Sopenharmony_ciprice. Our General Public Licenses are designed to make sure that you 238d6344f9Sopenharmony_cihave the freedom to distribute copies of free software (and charge for 248d6344f9Sopenharmony_cithis service if you wish), that you receive source code or can get it 258d6344f9Sopenharmony_ciif you want it, that you can change the software or use pieces of it 268d6344f9Sopenharmony_ciin new free programs; and that you know you can do these things. 278d6344f9Sopenharmony_ci 288d6344f9Sopenharmony_ci To protect your rights, we need to make restrictions that forbid 298d6344f9Sopenharmony_cianyone to deny you these rights or to ask you to surrender the rights. 308d6344f9Sopenharmony_ciThese restrictions translate to certain responsibilities for you if you 318d6344f9Sopenharmony_cidistribute copies of the software, or if you modify it. 328d6344f9Sopenharmony_ci 338d6344f9Sopenharmony_ci For example, if you distribute copies of such a program, whether 348d6344f9Sopenharmony_cigratis or for a fee, you must give the recipients all the rights that 358d6344f9Sopenharmony_ciyou have. You must make sure that they, too, receive or can get the 368d6344f9Sopenharmony_cisource code. And you must show them these terms so they know their 378d6344f9Sopenharmony_cirights. 388d6344f9Sopenharmony_ci 398d6344f9Sopenharmony_ci We protect your rights with two steps: (1) copyright the software, and 408d6344f9Sopenharmony_ci(2) offer you this license which gives you legal permission to copy, 418d6344f9Sopenharmony_cidistribute and/or modify the software. 428d6344f9Sopenharmony_ci 438d6344f9Sopenharmony_ci Also, for each author's protection and ours, we want to make certain 448d6344f9Sopenharmony_cithat everyone understands that there is no warranty for this free 458d6344f9Sopenharmony_cisoftware. If the software is modified by someone else and passed on, we 468d6344f9Sopenharmony_ciwant its recipients to know that what they have is not the original, so 478d6344f9Sopenharmony_cithat any problems introduced by others will not reflect on the original 488d6344f9Sopenharmony_ciauthors' reputations. 498d6344f9Sopenharmony_ci 508d6344f9Sopenharmony_ci Finally, any free program is threatened constantly by software 518d6344f9Sopenharmony_cipatents. We wish to avoid the danger that redistributors of a free 528d6344f9Sopenharmony_ciprogram will individually obtain patent licenses, in effect making the 538d6344f9Sopenharmony_ciprogram proprietary. To prevent this, we have made it clear that any 548d6344f9Sopenharmony_cipatent must be licensed for everyone's free use or not licensed at all. 558d6344f9Sopenharmony_ci 568d6344f9Sopenharmony_ci The precise terms and conditions for copying, distribution and 578d6344f9Sopenharmony_cimodification follow. 588d6344f9Sopenharmony_ci 598d6344f9Sopenharmony_ci GNU GENERAL PUBLIC LICENSE 608d6344f9Sopenharmony_ci TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 618d6344f9Sopenharmony_ci 628d6344f9Sopenharmony_ci 0. This License applies to any program or other work which contains 638d6344f9Sopenharmony_cia notice placed by the copyright holder saying it may be distributed 648d6344f9Sopenharmony_ciunder the terms of this General Public License. The "Program", below, 658d6344f9Sopenharmony_cirefers to any such program or work, and a "work based on the Program" 668d6344f9Sopenharmony_cimeans either the Program or any derivative work under copyright law: 678d6344f9Sopenharmony_cithat is to say, a work containing the Program or a portion of it, 688d6344f9Sopenharmony_cieither verbatim or with modifications and/or translated into another 698d6344f9Sopenharmony_cilanguage. (Hereinafter, translation is included without limitation in 708d6344f9Sopenharmony_cithe term "modification".) Each licensee is addressed as "you". 718d6344f9Sopenharmony_ci 728d6344f9Sopenharmony_ciActivities other than copying, distribution and modification are not 738d6344f9Sopenharmony_cicovered by this License; they are outside its scope. The act of 748d6344f9Sopenharmony_cirunning the Program is not restricted, and the output from the Program 758d6344f9Sopenharmony_ciis covered only if its contents constitute a work based on the 768d6344f9Sopenharmony_ciProgram (independent of having been made by running the Program). 778d6344f9Sopenharmony_ciWhether that is true depends on what the Program does. 788d6344f9Sopenharmony_ci 798d6344f9Sopenharmony_ci 1. You may copy and distribute verbatim copies of the Program's 808d6344f9Sopenharmony_cisource code as you receive it, in any medium, provided that you 818d6344f9Sopenharmony_ciconspicuously and appropriately publish on each copy an appropriate 828d6344f9Sopenharmony_cicopyright notice and disclaimer of warranty; keep intact all the 838d6344f9Sopenharmony_cinotices that refer to this License and to the absence of any warranty; 848d6344f9Sopenharmony_ciand give any other recipients of the Program a copy of this License 858d6344f9Sopenharmony_cialong with the Program. 868d6344f9Sopenharmony_ci 878d6344f9Sopenharmony_ciYou may charge a fee for the physical act of transferring a copy, and 888d6344f9Sopenharmony_ciyou may at your option offer warranty protection in exchange for a fee. 898d6344f9Sopenharmony_ci 908d6344f9Sopenharmony_ci 2. You may modify your copy or copies of the Program or any portion 918d6344f9Sopenharmony_ciof it, thus forming a work based on the Program, and copy and 928d6344f9Sopenharmony_cidistribute such modifications or work under the terms of Section 1 938d6344f9Sopenharmony_ciabove, provided that you also meet all of these conditions: 948d6344f9Sopenharmony_ci 958d6344f9Sopenharmony_ci a) You must cause the modified files to carry prominent notices 968d6344f9Sopenharmony_ci stating that you changed the files and the date of any change. 978d6344f9Sopenharmony_ci 988d6344f9Sopenharmony_ci b) You must cause any work that you distribute or publish, that in 998d6344f9Sopenharmony_ci whole or in part contains or is derived from the Program or any 1008d6344f9Sopenharmony_ci part thereof, to be licensed as a whole at no charge to all third 1018d6344f9Sopenharmony_ci parties under the terms of this License. 1028d6344f9Sopenharmony_ci 1038d6344f9Sopenharmony_ci c) If the modified program normally reads commands interactively 1048d6344f9Sopenharmony_ci when run, you must cause it, when started running for such 1058d6344f9Sopenharmony_ci interactive use in the most ordinary way, to print or display an 1068d6344f9Sopenharmony_ci announcement including an appropriate copyright notice and a 1078d6344f9Sopenharmony_ci notice that there is no warranty (or else, saying that you provide 1088d6344f9Sopenharmony_ci a warranty) and that users may redistribute the program under 1098d6344f9Sopenharmony_ci these conditions, and telling the user how to view a copy of this 1108d6344f9Sopenharmony_ci License. (Exception: if the Program itself is interactive but 1118d6344f9Sopenharmony_ci does not normally print such an announcement, your work based on 1128d6344f9Sopenharmony_ci the Program is not required to print an announcement.) 1138d6344f9Sopenharmony_ci 1148d6344f9Sopenharmony_ciThese requirements apply to the modified work as a whole. If 1158d6344f9Sopenharmony_ciidentifiable sections of that work are not derived from the Program, 1168d6344f9Sopenharmony_ciand can be reasonably considered independent and separate works in 1178d6344f9Sopenharmony_cithemselves, then this License, and its terms, do not apply to those 1188d6344f9Sopenharmony_cisections when you distribute them as separate works. But when you 1198d6344f9Sopenharmony_cidistribute the same sections as part of a whole which is a work based 1208d6344f9Sopenharmony_cion the Program, the distribution of the whole must be on the terms of 1218d6344f9Sopenharmony_cithis License, whose permissions for other licensees extend to the 1228d6344f9Sopenharmony_cientire whole, and thus to each and every part regardless of who wrote it. 1238d6344f9Sopenharmony_ci 1248d6344f9Sopenharmony_ciThus, it is not the intent of this section to claim rights or contest 1258d6344f9Sopenharmony_ciyour rights to work written entirely by you; rather, the intent is to 1268d6344f9Sopenharmony_ciexercise the right to control the distribution of derivative or 1278d6344f9Sopenharmony_cicollective works based on the Program. 1288d6344f9Sopenharmony_ci 1298d6344f9Sopenharmony_ciIn addition, mere aggregation of another work not based on the Program 1308d6344f9Sopenharmony_ciwith the Program (or with a work based on the Program) on a volume of 1318d6344f9Sopenharmony_cia storage or distribution medium does not bring the other work under 1328d6344f9Sopenharmony_cithe scope of this License. 1338d6344f9Sopenharmony_ci 1348d6344f9Sopenharmony_ci 3. You may copy and distribute the Program (or a work based on it, 1358d6344f9Sopenharmony_ciunder Section 2) in object code or executable form under the terms of 1368d6344f9Sopenharmony_ciSections 1 and 2 above provided that you also do one of the following: 1378d6344f9Sopenharmony_ci 1388d6344f9Sopenharmony_ci a) Accompany it with the complete corresponding machine-readable 1398d6344f9Sopenharmony_ci source code, which must be distributed under the terms of Sections 1408d6344f9Sopenharmony_ci 1 and 2 above on a medium customarily used for software interchange; or, 1418d6344f9Sopenharmony_ci 1428d6344f9Sopenharmony_ci b) Accompany it with a written offer, valid for at least three 1438d6344f9Sopenharmony_ci years, to give any third party, for a charge no more than your 1448d6344f9Sopenharmony_ci cost of physically performing source distribution, a complete 1458d6344f9Sopenharmony_ci machine-readable copy of the corresponding source code, to be 1468d6344f9Sopenharmony_ci distributed under the terms of Sections 1 and 2 above on a medium 1478d6344f9Sopenharmony_ci customarily used for software interchange; or, 1488d6344f9Sopenharmony_ci 1498d6344f9Sopenharmony_ci c) Accompany it with the information you received as to the offer 1508d6344f9Sopenharmony_ci to distribute corresponding source code. (This alternative is 1518d6344f9Sopenharmony_ci allowed only for noncommercial distribution and only if you 1528d6344f9Sopenharmony_ci received the program in object code or executable form with such 1538d6344f9Sopenharmony_ci an offer, in accord with Subsection b above.) 1548d6344f9Sopenharmony_ci 1558d6344f9Sopenharmony_ciThe source code for a work means the preferred form of the work for 1568d6344f9Sopenharmony_cimaking modifications to it. For an executable work, complete source 1578d6344f9Sopenharmony_cicode means all the source code for all modules it contains, plus any 1588d6344f9Sopenharmony_ciassociated interface definition files, plus the scripts used to 1598d6344f9Sopenharmony_cicontrol compilation and installation of the executable. However, as a 1608d6344f9Sopenharmony_cispecial exception, the source code distributed need not include 1618d6344f9Sopenharmony_cianything that is normally distributed (in either source or binary 1628d6344f9Sopenharmony_ciform) with the major components (compiler, kernel, and so on) of the 1638d6344f9Sopenharmony_cioperating system on which the executable runs, unless that component 1648d6344f9Sopenharmony_ciitself accompanies the executable. 1658d6344f9Sopenharmony_ci 1668d6344f9Sopenharmony_ciIf distribution of executable or object code is made by offering 1678d6344f9Sopenharmony_ciaccess to copy from a designated place, then offering equivalent 1688d6344f9Sopenharmony_ciaccess to copy the source code from the same place counts as 1698d6344f9Sopenharmony_cidistribution of the source code, even though third parties are not 1708d6344f9Sopenharmony_cicompelled to copy the source along with the object code. 1718d6344f9Sopenharmony_ci 1728d6344f9Sopenharmony_ci 4. You may not copy, modify, sublicense, or distribute the Program 1738d6344f9Sopenharmony_ciexcept as expressly provided under this License. Any attempt 1748d6344f9Sopenharmony_ciotherwise to copy, modify, sublicense or distribute the Program is 1758d6344f9Sopenharmony_civoid, and will automatically terminate your rights under this License. 1768d6344f9Sopenharmony_ciHowever, parties who have received copies, or rights, from you under 1778d6344f9Sopenharmony_cithis License will not have their licenses terminated so long as such 1788d6344f9Sopenharmony_ciparties remain in full compliance. 1798d6344f9Sopenharmony_ci 1808d6344f9Sopenharmony_ci 5. You are not required to accept this License, since you have not 1818d6344f9Sopenharmony_cisigned it. However, nothing else grants you permission to modify or 1828d6344f9Sopenharmony_cidistribute the Program or its derivative works. These actions are 1838d6344f9Sopenharmony_ciprohibited by law if you do not accept this License. Therefore, by 1848d6344f9Sopenharmony_cimodifying or distributing the Program (or any work based on the 1858d6344f9Sopenharmony_ciProgram), you indicate your acceptance of this License to do so, and 1868d6344f9Sopenharmony_ciall its terms and conditions for copying, distributing or modifying 1878d6344f9Sopenharmony_cithe Program or works based on it. 1888d6344f9Sopenharmony_ci 1898d6344f9Sopenharmony_ci 6. Each time you redistribute the Program (or any work based on the 1908d6344f9Sopenharmony_ciProgram), the recipient automatically receives a license from the 1918d6344f9Sopenharmony_cioriginal licensor to copy, distribute or modify the Program subject to 1928d6344f9Sopenharmony_cithese terms and conditions. You may not impose any further 1938d6344f9Sopenharmony_cirestrictions on the recipients' exercise of the rights granted herein. 1948d6344f9Sopenharmony_ciYou are not responsible for enforcing compliance by third parties to 1958d6344f9Sopenharmony_cithis License. 1968d6344f9Sopenharmony_ci 1978d6344f9Sopenharmony_ci 7. If, as a consequence of a court judgment or allegation of patent 1988d6344f9Sopenharmony_ciinfringement or for any other reason (not limited to patent issues), 1998d6344f9Sopenharmony_ciconditions are imposed on you (whether by court order, agreement or 2008d6344f9Sopenharmony_ciotherwise) that contradict the conditions of this License, they do not 2018d6344f9Sopenharmony_ciexcuse you from the conditions of this License. If you cannot 2028d6344f9Sopenharmony_cidistribute so as to satisfy simultaneously your obligations under this 2038d6344f9Sopenharmony_ciLicense and any other pertinent obligations, then as a consequence you 2048d6344f9Sopenharmony_cimay not distribute the Program at all. For example, if a patent 2058d6344f9Sopenharmony_cilicense would not permit royalty-free redistribution of the Program by 2068d6344f9Sopenharmony_ciall those who receive copies directly or indirectly through you, then 2078d6344f9Sopenharmony_cithe only way you could satisfy both it and this License would be to 2088d6344f9Sopenharmony_cirefrain entirely from distribution of the Program. 2098d6344f9Sopenharmony_ci 2108d6344f9Sopenharmony_ciIf any portion of this section is held invalid or unenforceable under 2118d6344f9Sopenharmony_ciany particular circumstance, the balance of the section is intended to 2128d6344f9Sopenharmony_ciapply and the section as a whole is intended to apply in other 2138d6344f9Sopenharmony_cicircumstances. 2148d6344f9Sopenharmony_ci 2158d6344f9Sopenharmony_ciIt is not the purpose of this section to induce you to infringe any 2168d6344f9Sopenharmony_cipatents or other property right claims or to contest validity of any 2178d6344f9Sopenharmony_cisuch claims; this section has the sole purpose of protecting the 2188d6344f9Sopenharmony_ciintegrity of the free software distribution system, which is 2198d6344f9Sopenharmony_ciimplemented by public license practices. Many people have made 2208d6344f9Sopenharmony_cigenerous contributions to the wide range of software distributed 2218d6344f9Sopenharmony_cithrough that system in reliance on consistent application of that 2228d6344f9Sopenharmony_cisystem; it is up to the author/donor to decide if he or she is willing 2238d6344f9Sopenharmony_cito distribute software through any other system and a licensee cannot 2248d6344f9Sopenharmony_ciimpose that choice. 2258d6344f9Sopenharmony_ci 2268d6344f9Sopenharmony_ciThis section is intended to make thoroughly clear what is believed to 2278d6344f9Sopenharmony_cibe a consequence of the rest of this License. 2288d6344f9Sopenharmony_ci 2298d6344f9Sopenharmony_ci 8. If the distribution and/or use of the Program is restricted in 2308d6344f9Sopenharmony_cicertain countries either by patents or by copyrighted interfaces, the 2318d6344f9Sopenharmony_cioriginal copyright holder who places the Program under this License 2328d6344f9Sopenharmony_cimay add an explicit geographical distribution limitation excluding 2338d6344f9Sopenharmony_cithose countries, so that distribution is permitted only in or among 2348d6344f9Sopenharmony_cicountries not thus excluded. In such case, this License incorporates 2358d6344f9Sopenharmony_cithe limitation as if written in the body of this License. 2368d6344f9Sopenharmony_ci 2378d6344f9Sopenharmony_ci 9. The Free Software Foundation may publish revised and/or new versions 2388d6344f9Sopenharmony_ciof the General Public License from time to time. Such new versions will 2398d6344f9Sopenharmony_cibe similar in spirit to the present version, but may differ in detail to 2408d6344f9Sopenharmony_ciaddress new problems or concerns. 2418d6344f9Sopenharmony_ci 2428d6344f9Sopenharmony_ciEach version is given a distinguishing version number. If the Program 2438d6344f9Sopenharmony_cispecifies a version number of this License which applies to it and "any 2448d6344f9Sopenharmony_cilater version", you have the option of following the terms and conditions 2458d6344f9Sopenharmony_cieither of that version or of any later version published by the Free 2468d6344f9Sopenharmony_ciSoftware Foundation. If the Program does not specify a version number of 2478d6344f9Sopenharmony_cithis License, you may choose any version ever published by the Free Software 2488d6344f9Sopenharmony_ciFoundation. 2498d6344f9Sopenharmony_ci 2508d6344f9Sopenharmony_ci 10. If you wish to incorporate parts of the Program into other free 2518d6344f9Sopenharmony_ciprograms whose distribution conditions are different, write to the author 2528d6344f9Sopenharmony_cito ask for permission. For software which is copyrighted by the Free 2538d6344f9Sopenharmony_ciSoftware Foundation, write to the Free Software Foundation; we sometimes 2548d6344f9Sopenharmony_cimake exceptions for this. Our decision will be guided by the two goals 2558d6344f9Sopenharmony_ciof preserving the free status of all derivatives of our free software and 2568d6344f9Sopenharmony_ciof promoting the sharing and reuse of software generally. 2578d6344f9Sopenharmony_ci 2588d6344f9Sopenharmony_ci NO WARRANTY 2598d6344f9Sopenharmony_ci 2608d6344f9Sopenharmony_ci 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 2618d6344f9Sopenharmony_ciFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 2628d6344f9Sopenharmony_ciOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 2638d6344f9Sopenharmony_ciPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 2648d6344f9Sopenharmony_ciOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 2658d6344f9Sopenharmony_ciMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 2668d6344f9Sopenharmony_ciTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
