| GNU GENERAL PUBLIC LICENSE<br> |
| Version 2, June 1991<br> |
| <br> |
| Copyright (C) 1989, 1991 Free Software Foundation, Inc.,<br> |
| 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA<br> |
| Everyone is permitted to copy and distribute verbatim copies<br> |
| of this license document, but changing it is not allowed.<br> |
| <br> |
| Preamble<br> |
| <br> |
| The licenses for most software are designed to take away your<br> |
| freedom to share and change it. By contrast, the GNU General Public<br> |
| License is intended to guarantee your freedom to share and change free<br> |
| software--to make sure the software is free for all its users. This<br> |
| General Public License applies to most of the Free Software<br> |
| Foundation's software and to any other program whose authors commit to<br> |
| using it. (Some other Free Software Foundation software is covered by<br> |
| the GNU Lesser General Public License instead.) You can apply it to<br> |
| your programs, too.<br> |
| <br> |
| When we speak of free software, we are referring to freedom, not<br> |
| price. Our General Public Licenses are designed to make sure that you<br> |
| have the freedom to distribute copies of free software (and charge for<br> |
| this service if you wish), that you receive source code or can get it<br> |
| if you want it, that you can change the software or use pieces of it<br> |
| in new free programs; and that you know you can do these things.<br> |
| <br> |
| To protect your rights, we need to make restrictions that forbid<br> |
| anyone to deny you these rights or to ask you to surrender the rights.<br> |
| These restrictions translate to certain responsibilities for you if you<br> |
| distribute copies of the software, or if you modify it.<br> |
| <br> |
| For example, if you distribute copies of such a program, whether<br> |
| gratis or for a fee, you must give the recipients all the rights that<br> |
| you have. You must make sure that they, too, receive or can get the<br> |
| source code. And you must show them these terms so they know their<br> |
| rights.<br> |
| <br> |
| We protect your rights with two steps: (1) copyright the software, and<br> |
| (2) offer you this license which gives you legal permission to copy,<br> |
| distribute and/or modify the software.<br> |
| <br> |
| Also, for each author's protection and ours, we want to make certain<br> |
| that everyone understands that there is no warranty for this free<br> |
| software. If the software is modified by someone else and passed on, we<br> |
| want its recipients to know that what they have is not the original, so<br> |
| that any problems introduced by others will not reflect on the original<br> |
| authors' reputations.<br> |
| <br> |
| Finally, any free program is threatened constantly by software<br> |
| patents. We wish to avoid the danger that redistributors of a free<br> |
| program will individually obtain patent licenses, in effect making the<br> |
| program proprietary. To prevent this, we have made it clear that any<br> |
| patent must be licensed for everyone's free use or not licensed at all.<br> |
| <br> |
| The precise terms and conditions for copying, distribution and<br> |
| modification follow.<br> |
| <br> |
| GNU GENERAL PUBLIC LICENSE<br> |
| TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br> |
| <br> |
| 0. This License applies to any program or other work which contains<br> |
| a notice placed by the copyright holder saying it may be distributed<br> |
| under the terms of this General Public License. The "Program", below,<br> |
| refers to any such program or work, and a "work based on the Program"<br> |
| means either the Program or any derivative work under copyright law:<br> |
| that is to say, a work containing the Program or a portion of it,<br> |
| either verbatim or with modifications and/or translated into another<br> |
| language. (Hereinafter, translation is included without limitation in<br> |
| the term "modification".) Each licensee is addressed as "you".<br> |
| <br> |
| Activities other than copying, distribution and modification are not<br> |
| covered by this License; they are outside its scope. The act of<br> |
| running the Program is not restricted, and the output from the Program<br> |
| is covered only if its contents constitute a work based on the<br> |
| Program (independent of having been made by running the Program).<br> |
| Whether that is true depends on what the Program does.<br> |
| <br> |
| 1. You may copy and distribute verbatim copies of the Program's<br> |
| source code as you receive it, in any medium, provided that you<br> |
| conspicuously and appropriately publish on each copy an appropriate<br> |
| copyright notice and disclaimer of warranty; keep intact all the<br> |
| notices that refer to this License and to the absence of any warranty;<br> |
| and give any other recipients of the Program a copy of this License<br> |
| along with the Program.<br> |
| <br> |
| You may charge a fee for the physical act of transferring a copy, and<br> |
| you may at your option offer warranty protection in exchange for a fee.<br> |
| <br> |
| 2. You may modify your copy or copies of the Program or any portion<br> |
| of it, thus forming a work based on the Program, and copy and<br> |
| distribute such modifications or work under the terms of Section 1<br> |
| above, provided that you also meet all of these conditions:<br> |
| <br> |
| a) You must cause the modified files to carry prominent notices<br> |
| stating that you changed the files and the date of any change.<br> |
| <br> |
| b) You must cause any work that you distribute or publish, that in<br> |
| whole or in part contains or is derived from the Program or any<br> |
| part thereof, to be licensed as a whole at no charge to all third<br> |
| parties under the terms of this License.<br> |
| <br> |
| c) If the modified program normally reads commands interactively<br> |
| when run, you must cause it, when started running for such<br> |
| interactive use in the most ordinary way, to print or display an<br> |
| announcement including an appropriate copyright notice and a<br> |
| notice that there is no warranty (or else, saying that you provide<br> |
| a warranty) and that users may redistribute the program under<br> |
| these conditions, and telling the user how to view a copy of this<br> |
| License. (Exception: if the Program itself is interactive but<br> |
| does not normally print such an announcement, your work based on<br> |
| the Program is not required to print an announcement.)<br> |
| <br> |
| These requirements apply to the modified work as a whole. If<br> |
| identifiable sections of that work are not derived from the Program,<br> |
| and can be reasonably considered independent and separate works in<br> |
| themselves, then this License, and its terms, do not apply to those<br> |
| sections when you distribute them as separate works. But when you<br> |
| distribute the same sections as part of a whole which is a work based<br> |
| on the Program, the distribution of the whole must be on the terms of<br> |
| this License, whose permissions for other licensees extend to the<br> |
| entire whole, and thus to each and every part regardless of who wrote it.<br> |
| <br> |
| Thus, it is not the intent of this section to claim rights or contest<br> |
| your rights to work written entirely by you; rather, the intent is to<br> |
| exercise the right to control the distribution of derivative or<br> |
| collective works based on the Program.<br> |
| <br> |
| In addition, mere aggregation of another work not based on the Program<br> |
| with the Program (or with a work based on the Program) on a volume of<br> |
| a storage or distribution medium does not bring the other work under<br> |
| the scope of this License.<br> |
| <br> |
| 3. You may copy and distribute the Program (or a work based on it,<br> |
| under Section 2) in object code or executable form under the terms of<br> |
| Sections 1 and 2 above provided that you also do one of the following:<br> |
| <br> |
| a) Accompany it with the complete corresponding machine-readable<br> |
| source code, which must be distributed under the terms of Sections<br> |
| 1 and 2 above on a medium customarily used for software interchange; or,<br> |
| <br> |
| b) Accompany it with a written offer, valid for at least three<br> |
| years, to give any third party, for a charge no more than your<br> |
| cost of physically performing source distribution, a complete<br> |
| machine-readable copy of the corresponding source code, to be<br> |
| distributed under the terms of Sections 1 and 2 above on a medium<br> |
| customarily used for software interchange; or,<br> |
| <br> |
| c) Accompany it with the information you received as to the offer<br> |
| to distribute corresponding source code. (This alternative is<br> |
| allowed only for noncommercial distribution and only if you<br> |
| received the program in object code or executable form with such<br> |
| an offer, in accord with Subsection b above.)<br> |
| <br> |
| The source code for a work means the preferred form of the work for<br> |
| making modifications to it. For an executable work, complete source<br> |
| code means all the source code for all modules it contains, plus any<br> |
| associated interface definition files, plus the scripts used to<br> |
| control compilation and installation of the executable. However, as a<br> |
| special exception, the source code distributed need not include<br> |
| anything that is normally distributed (in either source or binary<br> |
| form) with the major components (compiler, kernel, and so on) of the<br> |
| operating system on which the executable runs, unless that component<br> |
| itself accompanies the executable.<br> |
| <br> |
| If distribution of executable or object code is made by offering<br> |
| access to copy from a designated place, then offering equivalent<br> |
| access to copy the source code from the same place counts as<br> |
| distribution of the source code, even though third parties are not<br> |
| compelled to copy the source along with the object code.<br> |
| <br> |
| 4. You may not copy, modify, sublicense, or distribute the Program<br> |
| except as expressly provided under this License. Any attempt<br> |
| otherwise to copy, modify, sublicense or distribute the Program is<br> |
| void, and will automatically terminate your rights under this License.<br> |
| However, parties who have received copies, or rights, from you under<br> |
| this License will not have their licenses terminated so long as such<br> |
| parties remain in full compliance.<br> |
| <br> |
| 5. You are not required to accept this License, since you have not<br> |
| signed it. However, nothing else grants you permission to modify or<br> |
| distribute the Program or its derivative works. These actions are<br> |
| prohibited by law if you do not accept this License. Therefore, by<br> |
| modifying or distributing the Program (or any work based on the<br> |
| Program), you indicate your acceptance of this License to do so, and<br> |
| all its terms and conditions for copying, distributing or modifying<br> |
| the Program or works based on it.<br> |
| <br> |
| 6. Each time you redistribute the Program (or any work based on the<br> |
| Program), the recipient automatically receives a license from the<br> |
| original licensor to copy, distribute or modify the Program subject to<br> |
| these terms and conditions. You may not impose any further<br> |
| restrictions on the recipients' exercise of the rights granted herein.<br> |
| You are not responsible for enforcing compliance by third parties to<br> |
| this License.<br> |
| <br> |
| 7. If, as a consequence of a court judgment or allegation of patent<br> |
| infringement or for any other reason (not limited to patent issues),<br> |
| conditions are imposed on you (whether by court order, agreement or<br> |
| otherwise) that contradict the conditions of this License, they do not<br> |
| excuse you from the conditions of this License. If you cannot<br> |
| distribute so as to satisfy simultaneously your obligations under this<br> |
| License and any other pertinent obligations, then as a consequence you<br> |
| may not distribute the Program at all. For example, if a patent<br> |
| license would not permit royalty-free redistribution of the Program by<br> |
| all those who receive copies directly or indirectly through you, then<br> |
| the only way you could satisfy both it and this License would be to<br> |
| refrain entirely from distribution of the Program.<br> |
| <br> |
| If any portion of this section is held invalid or unenforceable under<br> |
| any particular circumstance, the balance of the section is intended to<br> |
| apply and the section as a whole is intended to apply in other<br> |
| circumstances.<br> |
| <br> |
| It is not the purpose of this section to induce you to infringe any<br> |
| patents or other property right claims or to contest validity of any<br> |
| such claims; this section has the sole purpose of protecting the<br> |
| integrity of the free software distribution system, which is<br> |
| implemented by public license practices. Many people have made<br> |
| generous contributions to the wide range of software distributed<br> |
| through that system in reliance on consistent application of that<br> |
| system; it is up to the author/donor to decide if he or she is willing<br> |
| to distribute software through any other system and a licensee cannot<br> |
| impose that choice.<br> |
| <br> |
| This section is intended to make thoroughly clear what is believed to<br> |
| be a consequence of the rest of this License.<br> |
| <br> |
| 8. If the distribution and/or use of the Program is restricted in<br> |
| certain countries either by patents or by copyrighted interfaces, the<br> |
| original copyright holder who places the Program under this License<br> |
| may add an explicit geographical distribution limitation excluding<br> |
| those countries, so that distribution is permitted only in or among<br> |
| countries not thus excluded. In such case, this License incorporates<br> |
| the limitation as if written in the body of this License.<br> |
| <br> |
| 9. The Free Software Foundation may publish revised and/or new versions<br> |
| of the General Public License from time to time. Such new versions will<br> |
| be similar in spirit to the present version, but may differ in detail to<br> |
| address new problems or concerns.<br> |
| <br> |
| Each version is given a distinguishing version number. If the Program<br> |
| specifies a version number of this License which applies to it and "any<br> |
| later version", you have the option of following the terms and conditions<br> |
| either of that version or of any later version published by the Free<br> |
| Software Foundation. If the Program does not specify a version number of<br> |
| this License, you may choose any version ever published by the Free Software<br> |
| Foundation.<br> |
| <br> |
| 10. If you wish to incorporate parts of the Program into other free<br> |
| programs whose distribution conditions are different, write to the author<br> |
| to ask for permission. For software which is copyrighted by the Free<br> |
| Software Foundation, write to the Free Software Foundation; we sometimes<br> |
| make exceptions for this. Our decision will be guided by the two goals<br> |
| of preserving the free status of all derivatives of our free software and<br> |
| of promoting the sharing and reuse of software generally.<br> |
| <br> |
| NO WARRANTY<br> |
| <br> |
| 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY<br> |
| FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN<br> |
| OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES<br> |
| PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED<br> |
| OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF<br> |
| MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS<br> |
| TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE<br> |
| PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,<br> |
| REPAIR OR CORRECTION.<br> |
| <br> |
| 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING<br> |
| WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR<br> |
| REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,<br> |
| INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING<br> |
| OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED<br> |
| TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY<br> |
| YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER<br> |
| PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE<br> |
| POSSIBILITY OF SUCH DAMAGES.<br> |
| <br> |
| END OF TERMS AND CONDITIONS<br> |
| <br> |
| How to Apply These Terms to Your New Programs<br> |
| <br> |
| If you develop a new program, and you want it to be of the greatest<br> |
| possible use to the public, the best way to achieve this is to make it<br> |
| free software which everyone can redistribute and change under these terms.<br> |
| <br> |
| To do so, attach the following notices to the program. It is safest<br> |
| to attach them to the start of each source file to most effectively<br> |
| convey the exclusion of warranty; and each file should have at least<br> |
| the "copyright" line and a pointer to where the full notice is found.<br> |
| <br> |
| <one line to give the program's name and a brief idea of what it does.><br> |
| Copyright (C) <year> <name of author><br> |
| <br> |
| This program is free software; you can redistribute it and/or modify<br> |
| it under the terms of the GNU General Public License as published by<br> |
| the Free Software Foundation; either version 2 of the License, or<br> |
| (at your option) any later version.<br> |
| <br> |
| This program is distributed in the hope that it will be useful,<br> |
| but WITHOUT ANY WARRANTY; without even the implied warranty of<br> |
| MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the<br> |
| GNU General Public License for more details.<br> |
| <br> |
| You should have received a copy of the GNU General Public License along<br> |
| with this program; if not, write to the Free Software Foundation, Inc.,<br> |
| 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.<br> |
| <br> |
| Also add information on how to contact you by electronic and paper mail.<br> |
| <br> |
| If the program is interactive, make it output a short notice like this<br> |
| when it starts in an interactive mode:<br> |
| <br> |
| Gnomovision version 69, Copyright (C) year name of author<br> |
| Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.<br> |
| This is free software, and you are welcome to redistribute it<br> |
| under certain conditions; type `show c' for details.<br> |
| <br> |
| The hypothetical commands `show w' and `show c' should show the appropriate<br> |
| parts of the General Public License. Of course, the commands you use may<br> |
| be called something other than `show w' and `show c'; they could even be<br> |
| mouse-clicks or menu items--whatever suits your program.<br> |
| <br> |
| You should also get your employer (if you work as a programmer) or your<br> |
| school, if any, to sign a "copyright disclaimer" for the program, if<br> |
| necessary. Here is a sample; alter the names:<br> |
| <br> |
| Yoyodyne, Inc., hereby disclaims all copyright interest in the program<br> |
| `Gnomovision' (which makes passes at compilers) written by James Hacker.<br> |
| <br> |
| <signature of Ty Coon>, 1 April 1989<br> |
| Ty Coon, President of Vice<br> |
| <br> |
| This General Public License does not permit incorporating your program into<br> |
| proprietary programs. If your program is a subroutine library, you may<br> |
| consider it more useful to permit linking proprietary applications with the<br> |
| library. If this is what you want to do, use the GNU Lesser General<br> |
| Public License instead of this License.<br> |
