211 APPENDIX OPEN SOURCE LICENSE GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin \ Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this li\ cense document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to\ share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share an\ d change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundations software and to any other program whose authors co\ mmit to using it. (Some other Free Software Foundation software is covered by \ the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price\ . Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free softwar\ e (and charge for this service if you wish), that you receive source code or can get it i\ f you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do thes\ e things. To protect your rights, we need to make restrictions that forbid anyone t\ o deny you these rights or to ask you to sur- render the rights. These restrictions translate to certain responsibilities for you if you \ distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether grati\ s or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and \ (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each authors protection and ours, we want to make certain tha\ t everyone understands that there is no war- ranty for this free software. If the software is modified by someone el\ se and passed on, we want its recipients to know that what they have is not the original, so \ that any problems introduced by others will not reflect on the original authors reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyones free \ use or not licensed at all. The precise terms and conditions for copying, distribution and modificat\ ion follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notic\ e placed by the copyright holder saying it may be distributed under the terms of this General Public License. The Program, below, refers to any such program or work, and a work based on the Program means either the Program or a\ ny derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or w\ ith modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term modification.\ ) Each licensee is addressed as you. Activities other than copying, distribution and modification are not cov\ ered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from th\ e Program is covered only if its contents constitute a work based on the Program (\ independent of having been made by running the Program). Whether that is true depends on what the Program does.
212 APPENDIX APPENDIX 1. You may copy and distribute verbatim copies of the Programs source code \ as you receive it, in any medium, pro- vided that you conspicuously and appropriately publish on each copy an a\ ppropriate copyright notice and disclaimer of warranty; keep intact all the notices\ that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of thi\ s License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, t\ hus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Se\ ction 1 above, provided that you also meet all of these conditions:a) You must cause the modified files to carry prominent notices stating that\ you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or \ in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to a\ ll third parties under the terms of this License. c) If the modified program normally reads commands interactively when r\ un, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copy- right notice and a notice that there is no warranty (or else, saying th\ at you provide a warranty) and that users may redistribute the program under these conditions, and telling the user ho\ w to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an\ announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiab\ le sections of that work are not derived from the Program, and can be reasonably considered independent and separate works\ in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separa\ te works. But when you distribute the same sections as part of a whole which is a work based on the Program, the di\ stribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire\ whole, and thus to each and every part regard- less of who wrote it. Thus, it is not the intent of this section to claim rights or contest yo\ ur rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivativ\ e or collective works based on the Program. In addition, mere aggregation of another work not based on the Program w\ ith the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not b\ ring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Se\ ction 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do\ one of the following: a) Accompany it with the complete corresponding machine-readable source cod\ e, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for sof\ tware interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machi\ ne-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above\ on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if y\ ou received the program in object code or exe- cutable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for maki\ ng modifications to it. For an executable work, complete source code means all the source code for all modules it \ contains, plus any associated interface defini- tion files, plus the scripts used to control compilation and installatio\ n of the executable. However, as a special excep- tion, the source code distributed need not include anything that is norm\ ally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable ru\ ns, unless that component itself accompanies the executable.
213 APPENDIX If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as \ distribution of the source code, even though third parties are not compelled to copy the source along with the object\ code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided und\ er this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically t\ erminate your rights under this License. However, parties who have received copies, or rights, from you under this Licen\ se will not have their licenses terminated so long as such parties remain in ful\ l compliance. 5. You are not required to accept this License, since you have not signed it\ . However, nothing else grants you permis- sion to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based \ on the Program), you indi- cate your acceptance of this License to do so, and all its terms and con\ ditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the P\ rogram), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions\ . You may not impose any further restrictions on the recipients exercise of t\ he rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent in\ fringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the con- ditions of this License, they do not excuse you from the conditions of t\ his License. If you cannot distribute so as to sat- isfy simultaneously your obligations under this License and any other pe\ rtinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license\ would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through y\ ou, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the P\ rogram. If any portion of this section is held invalid or unenforceable under an\ y particular circumstance, the balance of the sec- tion is intended to apply and the section as a whole is intended to appl\ y in other circumstances. It is not the purpose of this section to induce you to infringe any pate\ nts or other property right claims or to contest validity of any such claims; this section has the sole purpose of protec\ ting the integrity of the free software distribution system, which is implemented by public license practices. Many people h\ ave made generous contributions to the wide range of software distributed through that system in reliance on consist\ ent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software th\ rough any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be\ a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in cert\ ain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under t\ his License may add an explicit geographical distribution limitation excluding those countries, so that distribution \ is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if \ written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of \ the General Public License from time to time. Such new versions will be similar in spirit to the present versio\ n, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and any later version, you have the option of following \ the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Pro\ gram does not specify a version number of this License, you may choose any version ever published by the Free Soft\ ware Foundation. 10. If you wish to incorporate parts of the Program into other free pr\ ograms whose distribution conditions are different, write to the author to ask for permission. For software which is copyri\ ghted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Ou\ r decision will be guided by the two goals of preserving the free status of all derivatives of our free software an\ d of promoting the sharing and reuse of software generally.
214 APPENDIX APPENDIX NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest po\ ssible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and cha\ nge under these terms. To do so, attach the following notices to the program. It is safest to a\ ttach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at\ least the copyright line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it \ under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 o\ f the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITH\ OUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along w\ ith this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail.\ If the program is interactive, make it output a short notice like this w\ hen it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision \ comes with ABSOLUTELY NO WARRANTY; for details type `show w. This is free software, and you are welcome to redistribute it under cert\ ain conditions; type `show c for details. The hypothetical commands `show w and `show c should show the appropri\ ate parts of the General Public License. Of course, the commands you use may be called something other than `show\ w and `show c; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your\ school, if any, to sign a copyright disclaimer for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `G\ nomovision (which makes passes at compil- ers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program i\ nto proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applicat\ ions with the library. If this is what you want to do, use the GNU Lesser General Public License instead o\ f this License.
215 APPENDIX GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin \ Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this \ license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts \ as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to\ share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share \ and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some special\ ly designated software packages--typically libraries--of the Free Software Foundation and other authors who decide \ to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary Gen\ eral Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, no\ t price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of \ free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that \ you can change the software and use pieces of it in new free programs; and that you are informed that you can do these\ things. To protect your rights, we need to make restrictions that forbid distribu\ tors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you \ distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they\ can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the lib\ rary, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free l\ ibrary. Also, if the library is modified by someone else and passed on, the recipients should\ know that what they have is not the original version, so that the original authors reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free p\ rogram. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictiv\ e license from a patent holder. Therefore, we insist that any patent license obtained for a version of t\ he library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinar\ y GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated lib\ raries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking thos\ e libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of\ freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the Lesser General Public License because it does \ Less to protect the users freedom than the ordinary General Public License. It also provides other free software d\ evelopers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public Li\ cense for many libraries. However, the Lesser license provides advantages in certain special circumstance\ s. For example, on rare occasions, there may be a special need to encourage\ the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used no\ n-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free pro\ grams enables a greater number of people to use a large body of free software. For example, permission to use the GNU C\ Library in non-free programs enables many more people to use the whole GNU operating system, as well as its varian\ t, the GNU/Linux operating system.
216 APPENDIX APPENDIX Although the Lesser General Public License is Less protective of the use\ rs freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewit\ hal to run that program using a modified ver- sion of the Library. The precise terms and conditions for copying, distribution and modificat\ ion follow. Pay close attention to the differ- ence between a work based on the library and a work that uses the lib\ rary. The former contains code derived from the library, whereas the latter must be combined with the library in order to run.GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contain\ s a notice placed by the copyright holder or other authorized party saying it may be distributed \ under the terms of this Lesser General Public License (also called this License). Each licensee is addressed as y\ ou. A library means a collection of software functions and/or data prepared\ so as to be conveniently linked with applica- tion programs (which use some of those functions and data) to form exe\ cutables. The Library, below, refers to any such software library or work which has been distributed\ under these terms. A work based on the Library means either the Library or any derivative w\ ork under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modif\ ications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term modification.\ ) Source code for a work means the preferred form of the work for maki\ ng modifications to it. For a library, complete source code means all the source code for all modules it contains, plus \ any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not cov\ ered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and ou\ tput from such a program is covered only if its contents constitute a work based on the Library (independent of the use\ of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that \ uses the Library does. 1. You may copy and distribute verbatim copies of the Librarys complete sou\ rce code as you receive it, in any medi- um, provided that you conspicuously and appropriately publish on each co\ py an appropriate copyright notice and dis- claimer of warranty; keep intact all the notices that refer to this Lice\ nse and to the absence of any warranty; and distrib- ute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, t\ hus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Se\ ction 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that\ you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all t\ hird parties under the terms of this License. d) If a facility in the modified Library refers to a function or a tabl\ e of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then yo\ u must make a good faith effort to ensure that, in the event an application does not supply such fu\ nction or table, the facility still operates, and performs whatever part of its purpose remains meaningful.(For example, a function in a library to compute square roots has a pur\ pose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function\ or table used by this function must be optional: if the application does not supply it, the square root\ function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiab\ le sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in the\ mselves, then this License, and its terms, do not apply to those sections when you distribute them as separa\ te works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire\ whole, and thus to each and every part regard- less of who wrote it.
