aoqi@0: The GNU General Public License (GPL) aoqi@0: aoqi@0: Version 2, June 1991 aoqi@0: aoqi@0: Copyright (C) 1989, 1991 Free Software Foundation, Inc. robilad@1171: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA aoqi@0: aoqi@0: Everyone is permitted to copy and distribute verbatim copies of this license aoqi@0: document, but changing it is not allowed. aoqi@0: aoqi@0: Preamble aoqi@0: aoqi@0: The licenses for most software are designed to take away your freedom to share aoqi@0: and change it. By contrast, the GNU General Public License is intended to aoqi@0: guarantee your freedom to share and change free software--to make sure the aoqi@0: software is free for all its users. This General Public License applies to aoqi@0: most of the Free Software Foundation's software and to any other program whose aoqi@0: authors commit to using it. (Some other Free Software Foundation software is aoqi@0: covered by the GNU Library General Public License instead.) You can apply it to aoqi@0: your programs, too. aoqi@0: aoqi@0: When we speak of free software, we are referring to freedom, not price. Our aoqi@0: General Public Licenses are designed to make sure that you have the freedom to aoqi@0: distribute copies of free software (and charge for this service if you wish), aoqi@0: that you receive source code or can get it if you want it, that you can change aoqi@0: the software or use pieces of it in new free programs; and that you know you aoqi@0: can do these things. aoqi@0: aoqi@0: To protect your rights, we need to make restrictions that forbid anyone to deny aoqi@0: you these rights or to ask you to surrender the rights. These restrictions aoqi@0: translate to certain responsibilities for you if you distribute copies of the aoqi@0: software, or if you modify it. aoqi@0: aoqi@0: For example, if you distribute copies of such a program, whether gratis or for aoqi@0: a fee, you must give the recipients all the rights that you have. You must aoqi@0: make sure that they, too, receive or can get the source code. And you must aoqi@0: show them these terms so they know their rights. aoqi@0: aoqi@0: We protect your rights with two steps: (1) copyright the software, and (2) aoqi@0: offer you this license which gives you legal permission to copy, distribute aoqi@0: and/or modify the software. aoqi@0: aoqi@0: Also, for each author's protection and ours, we want to make certain that aoqi@0: everyone understands that there is no warranty for this free software. If the aoqi@0: software is modified by someone else and passed on, we want its recipients to aoqi@0: know that what they have is not the original, so that any problems introduced aoqi@0: by others will not reflect on the original authors' reputations. aoqi@0: aoqi@0: Finally, any free program is threatened constantly by software patents. We aoqi@0: wish to avoid the danger that redistributors of a free program will aoqi@0: individually obtain patent licenses, in effect making the program proprietary. aoqi@0: To prevent this, we have made it clear that any patent must be licensed for aoqi@0: everyone's free use or not licensed at all. aoqi@0: aoqi@0: The precise terms and conditions for copying, distribution and modification aoqi@0: follow. aoqi@0: aoqi@0: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION aoqi@0: aoqi@0: 0. This License applies to any program or other work which contains a notice aoqi@0: placed by the copyright holder saying it may be distributed under the terms of aoqi@0: this General Public License. The "Program", below, refers to any such program aoqi@0: or work, and a "work based on the Program" means either the Program or any aoqi@0: derivative work under copyright law: that is to say, a work containing the aoqi@0: Program or a portion of it, either verbatim or with modifications and/or aoqi@0: translated into another language. (Hereinafter, translation is included aoqi@0: without limitation in the term "modification".) Each licensee is addressed as aoqi@0: "you". aoqi@0: aoqi@0: Activities other than copying, distribution and modification are not covered by aoqi@0: this License; they are outside its scope. The act of running the Program is aoqi@0: not restricted, and the output from the Program is covered only if its contents aoqi@0: constitute a work based on the Program (independent of having been made by aoqi@0: running the Program). Whether that is true depends on what the Program does. aoqi@0: aoqi@0: 1. You may copy and distribute verbatim copies of the Program's source code as aoqi@0: you receive it, in any medium, provided that you conspicuously and aoqi@0: appropriately publish on each copy an appropriate copyright notice and aoqi@0: disclaimer of warranty; keep intact all the notices that refer to this License aoqi@0: and to the absence of any warranty; and give any other recipients of the aoqi@0: Program a copy of this License along with the Program. aoqi@0: aoqi@0: You may charge a fee for the physical act of transferring a copy, and you may aoqi@0: at your option offer warranty protection in exchange for a fee. aoqi@0: aoqi@0: 2. You may modify your copy or copies of the Program or any portion of it, thus aoqi@0: forming a work based on the Program, and copy and distribute such modifications aoqi@0: or work under the terms of Section 1 above, provided that you also meet all of aoqi@0: these conditions: aoqi@0: aoqi@0: a) You must cause the modified files to carry prominent notices stating aoqi@0: that you changed the files and the date of any change. aoqi@0: aoqi@0: b) You must cause any work that you distribute or publish, that in whole or aoqi@0: in part contains or is derived from the Program or any part thereof, to be aoqi@0: licensed as a whole at no charge to all third parties under the terms of aoqi@0: this License. aoqi@0: aoqi@0: c) If the modified program normally reads commands interactively when run, aoqi@0: you must cause it, when started running for such interactive use in the aoqi@0: most ordinary way, to print or display an announcement including an aoqi@0: appropriate copyright notice and a notice that there is no warranty (or aoqi@0: else, saying that you provide a warranty) and that users may redistribute aoqi@0: the program under these conditions, and telling the user how to view a copy aoqi@0: of this License. (Exception: if the Program itself is interactive but does aoqi@0: not normally print such an announcement, your work based on the Program is aoqi@0: not required to print an announcement.) aoqi@0: aoqi@0: These requirements apply to the modified work as a whole. If identifiable aoqi@0: sections of that work are not derived from the Program, and can be reasonably aoqi@0: considered independent and separate works in themselves, then this License, and aoqi@0: its terms, do not apply to those sections when you distribute them as separate aoqi@0: works. But when you distribute the same sections as part of a whole which is a aoqi@0: work based on the Program, the distribution of the whole must be on the terms aoqi@0: of this License, whose permissions for other licensees extend to the entire aoqi@0: whole, and thus to each and every part regardless of who wrote it. aoqi@0: aoqi@0: Thus, it is not the intent of this section to claim rights or contest your aoqi@0: rights to work written entirely by you; rather, the intent is to exercise the aoqi@0: right to control the distribution of derivative or collective works based on aoqi@0: the Program. aoqi@0: aoqi@0: In addition, mere aggregation of another work not based on the Program with the aoqi@0: Program (or with a work based on the Program) on a volume of a storage or aoqi@0: distribution medium does not bring the other work under the scope of this aoqi@0: License. aoqi@0: aoqi@0: 3. You may copy and distribute the Program (or a work based on it, under aoqi@0: Section 2) in object code or executable form under the terms of Sections 1 and aoqi@0: 2 above provided that you also do one of the following: aoqi@0: aoqi@0: a) Accompany it with the complete corresponding machine-readable source aoqi@0: code, which must be distributed under the terms of Sections 1 and 2 above aoqi@0: on a medium customarily used for software interchange; or, aoqi@0: aoqi@0: b) Accompany it with a written offer, valid for at least three years, to aoqi@0: give any third party, for a charge no more than your cost of physically aoqi@0: performing source distribution, a complete machine-readable copy of the aoqi@0: corresponding source code, to be distributed under the terms of Sections 1 aoqi@0: and 2 above on a medium customarily used for software interchange; or, aoqi@0: aoqi@0: c) Accompany it with the information you received as to the offer to aoqi@0: distribute corresponding source code. (This alternative is allowed only aoqi@0: for noncommercial distribution and only if you received the program in aoqi@0: object code or executable form with such an offer, in accord with aoqi@0: Subsection b above.) aoqi@0: aoqi@0: The source code for a work means the preferred form of the work for making aoqi@0: modifications to it. For an executable work, complete source code means all aoqi@0: the source code for all modules it contains, plus any associated interface aoqi@0: definition files, plus the scripts used to control compilation and installation aoqi@0: of the executable. However, as a special exception, the source code aoqi@0: distributed need not include anything that is normally distributed (in either aoqi@0: source or binary form) with the major components (compiler, kernel, and so on) aoqi@0: of the operating system on which the executable runs, unless that component aoqi@0: itself accompanies the executable. aoqi@0: aoqi@0: If distribution of executable or object code is made by offering access to copy aoqi@0: from a designated place, then offering equivalent access to copy the source aoqi@0: code from the same place counts as distribution of the source code, even though aoqi@0: third parties are not compelled to copy the source along with the object code. aoqi@0: aoqi@0: 4. You may not copy, modify, sublicense, or distribute the Program except as aoqi@0: expressly provided under this License. Any attempt otherwise to copy, modify, aoqi@0: sublicense or distribute the Program is void, and will automatically terminate aoqi@0: your rights under this License. However, parties who have received copies, or aoqi@0: rights, from you under this License will not have their licenses terminated so aoqi@0: long as such parties remain in full compliance. aoqi@0: aoqi@0: 5. You are not required to accept this License, since you have not signed it. aoqi@0: However, nothing else grants you permission to modify or distribute the Program aoqi@0: or its derivative works. These actions are prohibited by law if you do not aoqi@0: accept this License. Therefore, by modifying or distributing the Program (or aoqi@0: any work based on the Program), you indicate your acceptance of this License to aoqi@0: do so, and all its terms and conditions for copying, distributing or modifying aoqi@0: the Program or works based on it. aoqi@0: aoqi@0: 6. Each time you redistribute the Program (or any work based on the Program), aoqi@0: the recipient automatically receives a license from the original licensor to aoqi@0: copy, distribute or modify the Program subject to these terms and conditions. aoqi@0: You may not impose any further restrictions on the recipients' exercise of the aoqi@0: rights granted herein. You are not responsible for enforcing compliance by aoqi@0: third parties to this License. aoqi@0: aoqi@0: 7. If, as a consequence of a court judgment or allegation of patent aoqi@0: infringement or for any other reason (not limited to patent issues), conditions aoqi@0: are imposed on you (whether by court order, agreement or otherwise) that aoqi@0: contradict the conditions of this License, they do not excuse you from the aoqi@0: conditions of this License. If you cannot distribute so as to satisfy aoqi@0: simultaneously your obligations under this License and any other pertinent aoqi@0: obligations, then as a consequence you may not distribute the Program at all. aoqi@0: For example, if a patent license would not permit royalty-free redistribution aoqi@0: of the Program by all those who receive copies directly or indirectly through aoqi@0: you, then the only way you could satisfy both it and this License would be to aoqi@0: refrain entirely from distribution of the Program. aoqi@0: aoqi@0: If any portion of this section is held invalid or unenforceable under any aoqi@0: particular circumstance, the balance of the section is intended to apply and aoqi@0: the section as a whole is intended to apply in other circumstances. aoqi@0: aoqi@0: It is not the purpose of this section to induce you to infringe any patents or aoqi@0: other property right claims or to contest validity of any such claims; this aoqi@0: section has the sole purpose of protecting the integrity of the free software aoqi@0: distribution system, which is implemented by public license practices. Many aoqi@0: people have made generous contributions to the wide range of software aoqi@0: distributed through that system in reliance on consistent application of that aoqi@0: system; it is up to the author/donor to decide if he or she is willing to aoqi@0: distribute software through any other system and a licensee cannot impose that aoqi@0: choice. aoqi@0: aoqi@0: This section is intended to make thoroughly clear what is believed to be a aoqi@0: consequence of the rest of this License. aoqi@0: aoqi@0: 8. If the distribution and/or use of the Program is restricted in certain aoqi@0: countries either by patents or by copyrighted interfaces, the original aoqi@0: copyright holder who places the Program under this License may add an explicit aoqi@0: geographical distribution limitation excluding those countries, so that aoqi@0: distribution is permitted only in or among countries not thus excluded. In aoqi@0: such case, this License incorporates the limitation as if written in the body aoqi@0: of this License. aoqi@0: aoqi@0: 9. The Free Software Foundation may publish revised and/or new versions of the aoqi@0: General Public License from time to time. Such new versions will be similar in aoqi@0: spirit to the present version, but may differ in detail to address new problems aoqi@0: or concerns. aoqi@0: aoqi@0: Each version is given a distinguishing version number. If the Program aoqi@0: specifies a version number of this License which applies to it and "any later aoqi@0: version", you have the option of following the terms and conditions either of aoqi@0: that version or of any later version published by the Free Software Foundation. aoqi@0: If the Program does not specify a version number of this License, you may aoqi@0: choose any version ever published by the Free Software Foundation. aoqi@0: aoqi@0: 10. If you wish to incorporate parts of the Program into other free programs aoqi@0: whose distribution conditions are different, write to the author to ask for aoqi@0: permission. For software which is copyrighted by the Free Software Foundation, aoqi@0: write to the Free Software Foundation; we sometimes make exceptions for this. aoqi@0: Our decision will be guided by the two goals of preserving the free status of aoqi@0: all derivatives of our free software and of promoting the sharing and reuse of aoqi@0: software generally. aoqi@0: aoqi@0: NO WARRANTY aoqi@0: aoqi@0: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR aoqi@0: THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE aoqi@0: STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE aoqi@0: PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, aoqi@0: INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND aoqi@0: FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND aoqi@0: PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, aoqi@0: YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. aoqi@0: aoqi@0: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL aoqi@0: ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE aoqi@0: PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY aoqi@0: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR aoqi@0: INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA aoqi@0: BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A aoqi@0: FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER aoqi@0: OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. aoqi@0: aoqi@0: END OF TERMS AND CONDITIONS aoqi@0: aoqi@0: How to Apply These Terms to Your New Programs aoqi@0: aoqi@0: If you develop a new program, and you want it to be of the greatest possible aoqi@0: use to the public, the best way to achieve this is to make it free software aoqi@0: which everyone can redistribute and change under these terms. aoqi@0: aoqi@0: To do so, attach the following notices to the program. It is safest to attach aoqi@0: them to the start of each source file to most effectively convey the exclusion aoqi@0: of warranty; and each file should have at least the "copyright" line and a aoqi@0: pointer to where the full notice is found. aoqi@0: aoqi@0: One line to give the program's name and a brief idea of what it does. aoqi@0: aoqi@0: Copyright (C) aoqi@0: aoqi@0: This program is free software; you can redistribute it and/or modify it aoqi@0: under the terms of the GNU General Public License as published by the Free aoqi@0: Software Foundation; either version 2 of the License, or (at your option) aoqi@0: any later version. aoqi@0: aoqi@0: This program is distributed in the hope that it will be useful, but WITHOUT aoqi@0: ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or aoqi@0: FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for aoqi@0: more details. aoqi@0: aoqi@0: You should have received a copy of the GNU General Public License along robilad@1171: with this program; if not, write to the Free Software Foundation, Inc., robilad@1171: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. aoqi@0: aoqi@0: Also add information on how to contact you by electronic and paper mail. aoqi@0: aoqi@0: If the program is interactive, make it output a short notice like this when it aoqi@0: starts in an interactive mode: aoqi@0: aoqi@0: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes aoqi@0: with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free aoqi@0: software, and you are welcome to redistribute it under certain conditions; aoqi@0: type 'show c' for details. aoqi@0: aoqi@0: The hypothetical commands 'show w' and 'show c' should show the appropriate aoqi@0: parts of the General Public License. Of course, the commands you use may be aoqi@0: called something other than 'show w' and 'show c'; they could even be aoqi@0: mouse-clicks or menu items--whatever suits your program. aoqi@0: aoqi@0: You should also get your employer (if you work as a programmer) or your school, aoqi@0: if any, to sign a "copyright disclaimer" for the program, if necessary. Here aoqi@0: is a sample; alter the names: aoqi@0: aoqi@0: Yoyodyne, Inc., hereby disclaims all copyright interest in the program aoqi@0: 'Gnomovision' (which makes passes at compilers) written by James Hacker. aoqi@0: aoqi@0: signature of Ty Coon, 1 April 1989 aoqi@0: aoqi@0: Ty Coon, President of Vice aoqi@0: aoqi@0: This General Public License does not permit incorporating your program into aoqi@0: proprietary programs. If your program is a subroutine library, you may aoqi@0: consider it more useful to permit linking proprietary applications with the aoqi@0: library. If this is what you want to do, use the GNU Library General Public aoqi@0: License instead of this License. aoqi@0: aoqi@0: aoqi@0: "CLASSPATH" EXCEPTION TO THE GPL aoqi@0: aoqi@0: Certain source files distributed by Oracle America and/or its affiliates are aoqi@0: subject to the following clarification and special exception to the GPL, but aoqi@0: only where Oracle has expressly included in the particular source file's header aoqi@0: the words "Oracle designates this particular file as subject to the "Classpath" aoqi@0: exception as provided by Oracle in the LICENSE file that accompanied this code." aoqi@0: aoqi@0: Linking this library statically or dynamically with other modules is making aoqi@0: a combined work based on this library. Thus, the terms and conditions of aoqi@0: the GNU General Public License cover the whole combination. aoqi@0: aoqi@0: As a special exception, the copyright holders of this library give you aoqi@0: permission to link this library with independent modules to produce an aoqi@0: executable, regardless of the license terms of these independent modules, aoqi@0: and to copy and distribute the resulting executable under terms of your aoqi@0: choice, provided that you also meet, for each linked independent module, aoqi@0: the terms and conditions of the license of that module. An independent aoqi@0: module is a module which is not derived from or based on this library. If aoqi@0: you modify this library, you may extend this exception to your version of aoqi@0: the library, but you are not obligated to do so. If you do not wish to do aoqi@0: so, delete this exception statement from your version.
