rubidium@10385: GNU GENERAL PUBLIC LICENSE rubidium@10385: Version 2, June 1991 rubidium@10385: rubidium@10385: Copyright (C) 1989, 1991 Free Software Foundation, Inc. rubidium@10385: 675 Mass Ave, Cambridge, MA 02139, USA rubidium@10385: Everyone is permitted to copy and distribute verbatim copies rubidium@10385: of this license document, but changing it is not allowed. rubidium@10385: rubidium@10385: Preamble rubidium@10385: rubidium@10385: The licenses for most software are designed to take away your rubidium@10385: freedom to share and change it. By contrast, the GNU General Public rubidium@10385: License is intended to guarantee your freedom to share and change free rubidium@10385: software--to make sure the software is free for all its users. This rubidium@10385: General Public License applies to most of the Free Software rubidium@10385: Foundation's software and to any other program whose authors commit to rubidium@10385: using it. (Some other Free Software Foundation software is covered by rubidium@10385: the GNU Library General Public License instead.) You can apply it to rubidium@10385: your programs, too. rubidium@10385: rubidium@10385: When we speak of free software, we are referring to freedom, not rubidium@10385: price. Our General Public Licenses are designed to make sure that you rubidium@10385: have the freedom to distribute copies of free software (and charge for rubidium@10385: this service if you wish), that you receive source code or can get it rubidium@10385: if you want it, that you can change the software or use pieces of it rubidium@10385: in new free programs; and that you know you can do these things. rubidium@10385: rubidium@10385: To protect your rights, we need to make restrictions that forbid rubidium@10385: anyone to deny you these rights or to ask you to surrender the rights. rubidium@10385: These restrictions translate to certain responsibilities for you if you rubidium@10385: distribute copies of the software, or if you modify it. rubidium@10385: rubidium@10385: For example, if you distribute copies of such a program, whether rubidium@10385: gratis or for a fee, you must give the recipients all the rights that rubidium@10385: you have. You must make sure that they, too, receive or can get the rubidium@10385: source code. And you must show them these terms so they know their rubidium@10385: rights. rubidium@10385: rubidium@10385: We protect your rights with two steps: (1) copyright the software, and rubidium@10385: (2) offer you this license which gives you legal permission to copy, rubidium@10385: distribute and/or modify the software. rubidium@10385: rubidium@10385: Also, for each author's protection and ours, we want to make certain rubidium@10385: that everyone understands that there is no warranty for this free rubidium@10385: software. If the software is modified by someone else and passed on, we rubidium@10385: want its recipients to know that what they have is not the original, so rubidium@10385: that any problems introduced by others will not reflect on the original rubidium@10385: authors' reputations. rubidium@10385: rubidium@10385: Finally, any free program is threatened constantly by software rubidium@10385: patents. We wish to avoid the danger that redistributors of a free rubidium@10385: program will individually obtain patent licenses, in effect making the rubidium@10385: program proprietary. To prevent this, we have made it clear that any rubidium@10385: patent must be licensed for everyone's free use or not licensed at all. rubidium@10385: rubidium@10385: The precise terms and conditions for copying, distribution and rubidium@10385: modification follow. rubidium@10385: rubidium@10385: GNU GENERAL PUBLIC LICENSE rubidium@10385: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION rubidium@10385: rubidium@10385: 0. This License applies to any program or other work which contains rubidium@10385: a notice placed by the copyright holder saying it may be distributed rubidium@10385: under the terms of this General Public License. The "Program", below, rubidium@10385: refers to any such program or work, and a "work based on the Program" rubidium@10385: means either the Program or any derivative work under copyright law: rubidium@10385: that is to say, a work containing the Program or a portion of it, rubidium@10385: either verbatim or with modifications and/or translated into another rubidium@10385: language. (Hereinafter, translation is included without limitation in rubidium@10385: the term "modification".) Each licensee is addressed as "you". rubidium@10385: rubidium@10385: Activities other than copying, distribution and modification are not rubidium@10385: covered by this License; they are outside its scope. The act of rubidium@10385: running the Program is not restricted, and the output from the Program rubidium@10385: is covered only if its contents constitute a work based on the rubidium@10385: Program (independent of having been made by running the Program). rubidium@10385: Whether that is true depends on what the Program does. rubidium@10385: rubidium@10385: 1. You may copy and distribute verbatim copies of the Program's rubidium@10385: source code as you receive it, in any medium, provided that you rubidium@10385: conspicuously and appropriately publish on each copy an appropriate rubidium@10385: copyright notice and disclaimer of warranty; keep intact all the rubidium@10385: notices that refer to this License and to the absence of any warranty; rubidium@10385: and give any other recipients of the Program a copy of this License rubidium@10385: along with the Program. rubidium@10385: rubidium@10385: You may charge a fee for the physical act of transferring a copy, and rubidium@10385: you may at your option offer warranty protection in exchange for a fee. rubidium@10385: rubidium@10385: 2. You may modify your copy or copies of the Program or any portion rubidium@10385: of it, thus forming a work based on the Program, and copy and rubidium@10385: distribute such modifications or work under the terms of Section 1 rubidium@10385: above, provided that you also meet all of these conditions: rubidium@10385: rubidium@10385: a) You must cause the modified files to carry prominent notices rubidium@10385: stating that you changed the files and the date of any change. rubidium@10385: rubidium@10385: b) You must cause any work that you distribute or publish, that in rubidium@10385: whole or in part contains or is derived from the Program or any rubidium@10385: part thereof, to be licensed as a whole at no charge to all third rubidium@10385: parties under the terms of this License. rubidium@10385: rubidium@10385: c) If the modified program normally reads commands interactively rubidium@10385: when run, you must cause it, when started running for such rubidium@10385: interactive use in the most ordinary way, to print or display an rubidium@10385: announcement including an appropriate copyright notice and a rubidium@10385: notice that there is no warranty (or else, saying that you provide rubidium@10385: a warranty) and that users may redistribute the program under rubidium@10385: these conditions, and telling the user how to view a copy of this rubidium@10385: License. (Exception: if the Program itself is interactive but rubidium@10385: does not normally print such an announcement, your work based on rubidium@10385: the Program is not required to print an announcement.) rubidium@10385: rubidium@10385: These requirements apply to the modified work as a whole. If rubidium@10385: identifiable sections of that work are not derived from the Program, rubidium@10385: and can be reasonably considered independent and separate works in rubidium@10385: themselves, then this License, and its terms, do not apply to those rubidium@10385: sections when you distribute them as separate works. But when you rubidium@10385: distribute the same sections as part of a whole which is a work based rubidium@10385: on the Program, the distribution of the whole must be on the terms of rubidium@10385: this License, whose permissions for other licensees extend to the rubidium@10385: entire whole, and thus to each and every part regardless of who wrote it. rubidium@10385: rubidium@10385: Thus, it is not the intent of this section to claim rights or contest rubidium@10385: your rights to work written entirely by you; rather, the intent is to rubidium@10385: exercise the right to control the distribution of derivative or rubidium@10385: collective works based on the Program. rubidium@10385: rubidium@10385: In addition, mere aggregation of another work not based on the Program rubidium@10385: with the Program (or with a work based on the Program) on a volume of rubidium@10385: a storage or distribution medium does not bring the other work under rubidium@10385: the scope of this License. rubidium@10385: rubidium@10385: 3. You may copy and distribute the Program (or a work based on it, rubidium@10385: under Section 2) in object code or executable form under the terms of rubidium@10385: Sections 1 and 2 above provided that you also do one of the following: rubidium@10385: rubidium@10385: a) Accompany it with the complete corresponding machine-readable rubidium@10385: source code, which must be distributed under the terms of Sections rubidium@10385: 1 and 2 above on a medium customarily used for software interchange; or, rubidium@10385: rubidium@10385: b) Accompany it with a written offer, valid for at least three rubidium@10385: years, to give any third party, for a charge no more than your rubidium@10385: cost of physically performing source distribution, a complete rubidium@10385: machine-readable copy of the corresponding source code, to be rubidium@10385: distributed under the terms of Sections 1 and 2 above on a medium rubidium@10385: customarily used for software interchange; or, rubidium@10385: rubidium@10385: c) Accompany it with the information you received as to the offer rubidium@10385: to distribute corresponding source code. (This alternative is rubidium@10385: allowed only for noncommercial distribution and only if you rubidium@10385: received the program in object code or executable form with such rubidium@10385: an offer, in accord with Subsection b above.) rubidium@10385: rubidium@10385: The source code for a work means the preferred form of the work for rubidium@10385: making modifications to it. For an executable work, complete source rubidium@10385: code means all the source code for all modules it contains, plus any rubidium@10385: associated interface definition files, plus the scripts used to rubidium@10385: control compilation and installation of the executable. However, as a rubidium@10385: special exception, the source code distributed need not include rubidium@10385: anything that is normally distributed (in either source or binary rubidium@10385: form) with the major components (compiler, kernel, and so on) of the rubidium@10385: operating system on which the executable runs, unless that component rubidium@10385: itself accompanies the executable. rubidium@10385: rubidium@10385: If distribution of executable or object code is made by offering rubidium@10385: access to copy from a designated place, then offering equivalent rubidium@10385: access to copy the source code from the same place counts as rubidium@10385: distribution of the source code, even though third parties are not rubidium@10385: compelled to copy the source along with the object code. rubidium@10385: rubidium@10385: 4. You may not copy, modify, sublicense, or distribute the Program rubidium@10385: except as expressly provided under this License. Any attempt rubidium@10385: otherwise to copy, modify, sublicense or distribute the Program is rubidium@10385: void, and will automatically terminate your rights under this License. rubidium@10385: However, parties who have received copies, or rights, from you under rubidium@10385: this License will not have their licenses terminated so long as such rubidium@10385: parties remain in full compliance. rubidium@10385: rubidium@10385: 5. You are not required to accept this License, since you have not rubidium@10385: signed it. However, nothing else grants you permission to modify or rubidium@10385: distribute the Program or its derivative works. These actions are rubidium@10385: prohibited by law if you do not accept this License. Therefore, by rubidium@10385: modifying or distributing the Program (or any work based on the rubidium@10385: Program), you indicate your acceptance of this License to do so, and rubidium@10385: all its terms and conditions for copying, distributing or modifying rubidium@10385: the Program or works based on it. rubidium@10385: rubidium@10385: 6. Each time you redistribute the Program (or any work based on the rubidium@10385: Program), the recipient automatically receives a license from the rubidium@10385: original licensor to copy, distribute or modify the Program subject to rubidium@10385: these terms and conditions. You may not impose any further rubidium@10385: restrictions on the recipients' exercise of the rights granted herein. rubidium@10385: You are not responsible for enforcing compliance by third parties to rubidium@10385: this License. rubidium@10385: rubidium@10385: 7. If, as a consequence of a court judgment or allegation of patent rubidium@10385: infringement or for any other reason (not limited to patent issues), rubidium@10385: conditions are imposed on you (whether by court order, agreement or rubidium@10385: otherwise) that contradict the conditions of this License, they do not rubidium@10385: excuse you from the conditions of this License. If you cannot rubidium@10385: distribute so as to satisfy simultaneously your obligations under this rubidium@10385: License and any other pertinent obligations, then as a consequence you rubidium@10385: may not distribute the Program at all. For example, if a patent rubidium@10385: license would not permit royalty-free redistribution of the Program by rubidium@10385: all those who receive copies directly or indirectly through you, then rubidium@10385: the only way you could satisfy both it and this License would be to rubidium@10385: refrain entirely from distribution of the Program. rubidium@10385: rubidium@10385: If any portion of this section is held invalid or unenforceable under rubidium@10385: any particular circumstance, the balance of the section is intended to rubidium@10385: apply and the section as a whole is intended to apply in other rubidium@10385: circumstances. rubidium@10385: rubidium@10385: It is not the purpose of this section to induce you to infringe any rubidium@10385: patents or other property right claims or to contest validity of any rubidium@10385: such claims; this section has the sole purpose of protecting the rubidium@10385: integrity of the free software distribution system, which is rubidium@10385: implemented by public license practices. Many people have made rubidium@10385: generous contributions to the wide range of software distributed rubidium@10385: through that system in reliance on consistent application of that rubidium@10385: system; it is up to the author/donor to decide if he or she is willing rubidium@10385: to distribute software through any other system and a licensee cannot rubidium@10385: impose that choice. rubidium@10385: rubidium@10385: This section is intended to make thoroughly clear what is believed to rubidium@10385: be a consequence of the rest of this License. rubidium@10385: rubidium@10385: 8. If the distribution and/or use of the Program is restricted in rubidium@10385: certain countries either by patents or by copyrighted interfaces, the rubidium@10385: original copyright holder who places the Program under this License rubidium@10385: may add an explicit geographical distribution limitation excluding rubidium@10385: those countries, so that distribution is permitted only in or among rubidium@10385: countries not thus excluded. In such case, this License incorporates rubidium@10385: the limitation as if written in the body of this License. rubidium@10385: rubidium@10385: 9. The Free Software Foundation may publish revised and/or new versions rubidium@10385: of the General Public License from time to time. Such new versions will rubidium@10385: be similar in spirit to the present version, but may differ in detail to rubidium@10385: address new problems or concerns. rubidium@10385: rubidium@10385: Each version is given a distinguishing version number. If the Program rubidium@10385: specifies a version number of this License which applies to it and "any rubidium@10385: later version", you have the option of following the terms and conditions rubidium@10385: either of that version or of any later version published by the Free rubidium@10385: Software Foundation. If the Program does not specify a version number of rubidium@10385: this License, you may choose any version ever published by the Free Software rubidium@10385: Foundation. rubidium@10385: rubidium@10385: 10. If you wish to incorporate parts of the Program into other free rubidium@10385: programs whose distribution conditions are different, write to the author rubidium@10385: to ask for permission. For software which is copyrighted by the Free rubidium@10385: Software Foundation, write to the Free Software Foundation; we sometimes rubidium@10385: make exceptions for this. Our decision will be guided by the two goals rubidium@10385: of preserving the free status of all derivatives of our free software and rubidium@10385: of promoting the sharing and reuse of software generally. rubidium@10385: rubidium@10385: NO WARRANTY rubidium@10385: rubidium@10385: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY rubidium@10385: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN rubidium@10385: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES rubidium@10385: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED rubidium@10385: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF rubidium@10385: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS rubidium@10385: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE rubidium@10385: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, rubidium@10385: REPAIR OR CORRECTION. rubidium@10385: rubidium@10385: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING rubidium@10385: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR rubidium@10385: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, rubidium@10385: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING rubidium@10385: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED rubidium@10385: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY rubidium@10385: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER rubidium@10385: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE rubidium@10385: POSSIBILITY OF SUCH DAMAGES. rubidium@10385: rubidium@10385: END OF TERMS AND CONDITIONS rubidium@10385: rubidium@10385: Appendix: How to Apply These Terms to Your New Programs rubidium@10385: rubidium@10385: If you develop a new program, and you want it to be of the greatest rubidium@10385: possible use to the public, the best way to achieve this is to make it rubidium@10385: free software which everyone can redistribute and change under these terms. rubidium@10385: rubidium@10385: To do so, attach the following notices to the program. It is safest rubidium@10385: to attach them to the start of each source file to most effectively rubidium@10385: convey the exclusion of warranty; and each file should have at least rubidium@10385: the "copyright" line and a pointer to where the full notice is found. rubidium@10385: rubidium@10385: rubidium@10385: Copyright (C) 19yy rubidium@10385: rubidium@10385: This program is free software; you can redistribute it and/or modify rubidium@10385: it under the terms of the GNU General Public License as published by rubidium@10385: the Free Software Foundation; either version 2 of the License, or rubidium@10385: (at your option) any later version. rubidium@10385: rubidium@10385: This program is distributed in the hope that it will be useful, rubidium@10385: but WITHOUT ANY WARRANTY; without even the implied warranty of rubidium@10385: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the rubidium@10385: GNU General Public License for more details. rubidium@10385: rubidium@10385: You should have received a copy of the GNU General Public License rubidium@10385: along with this program; if not, write to the Free Software rubidium@10385: Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. rubidium@10385: rubidium@10385: Also add information on how to contact you by electronic and paper mail. rubidium@10385: rubidium@10385: If the program is interactive, make it output a short notice like this rubidium@10385: when it starts in an interactive mode: rubidium@10385: rubidium@10385: Gnomovision version 69, Copyright (C) 19yy name of author rubidium@10385: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. rubidium@10385: This is free software, and you are welcome to redistribute it rubidium@10385: under certain conditions; type `show c' for details. rubidium@10385: rubidium@10385: The hypothetical commands `show w' and `show c' should show the appropriate rubidium@10385: parts of the General Public License. Of course, the commands you use may rubidium@10385: be called something other than `show w' and `show c'; they could even be rubidium@10385: mouse-clicks or menu items--whatever suits your program. rubidium@10385: rubidium@10385: You should also get your employer (if you work as a programmer) or your rubidium@10385: school, if any, to sign a "copyright disclaimer" for the program, if rubidium@10385: necessary. Here is a sample; alter the names: rubidium@10385: rubidium@10385: Yoyodyne, Inc., hereby disclaims all copyright interest in the program rubidium@10385: `Gnomovision' (which makes passes at compilers) written by James Hacker. rubidium@10385: rubidium@10385: , 1 April 1989 rubidium@10385: Ty Coon, President of Vice rubidium@10385: rubidium@10385: This General Public License does not permit incorporating your program into rubidium@10385: proprietary programs. If your program is a subroutine library, you may rubidium@10385: consider it more useful to permit linking proprietary applications with the rubidium@10385: library. If this is what you want to do, use the GNU Library General rubidium@10385: Public License instead of this License.
