By contrast, the GNU General Public #-License is intended to guarantee your freedom to share and 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 #-Foundation's software and to any other program whose authors commit to #-using it. (Some other Free Software Foundation software is covered by #-the GNU Library 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 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 or use pieces of it #-in new free programs; and that you know you can do these things. #- #- To protect your rights, we need to make restrictions that forbid #-anyone to deny you these rights or to ask you to surrender 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 #-gratis 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 author's protection and ours, we want to make certain #-that everyone understands that there is no warranty for this free #-software. If the software is modified by someone else 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 everyone's free use or not licensed at all. #- #- The precise terms and conditions for copying, distribution and #-modification 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 notice 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 any derivative work under copyright law: #-that is to say, a work containing the Program or a portion of it, #-either verbatim or with 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 #-covered by this License; they are outside its scope. The act of #-running the Program is not restricted, and the output from the 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. #- #- 1. You may copy and distribute verbatim copies of the Program's #-source code as you receive it, in any medium, provided that you #-conspicuously and appropriately publish on each copy an appropriate #-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 this 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, thus forming a work based on the Program, and copy and #-distribute such modifications or work under the terms of Section 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 all third #- parties under the terms of this License. #- #- c) If the modified program normally reads commands interactively #- when run, 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 copyright notice and a #- notice that there is no warranty (or else, saying that you provide #- a warranty) and that users may redistribute the program under #- these conditions, and telling the user how 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 #-identifiable 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 separate works. But when you #-distribute the same sections as part of a whole which is a work based #-on the Program, 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 regardless of who wrote it. #- #-Thus, it is not the intent of this section to claim rights or contest #-your rights to work written entirely by you; rather, the intent is to #-exercise the right to control the distribution of derivative or #-collective works based on the Program. #- #-In addition, mere aggregation of another work not based on the Program #-with the Program (or with a work based on the Program) on a volume of #-a storage or distribution medium does not bring the other work under #-the scope of this License. #- #- 3. You may copy and distribute the Program (or a work based on it, #-under Section 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 code, which must be distributed under the terms of Sections #- 1 and 2 above on a medium customarily used for software 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 #- machine-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 you #- received the program in object code or executable 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 #-making modifications to it. For an executable work, 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 executable. However, as a #-special exception, the source code distributed need not include #-anything that is normally distributed (in either source or binary #-form) with the major components (compiler, kernel, and so on) of the #-operating system on which the executable runs, unless that component #-itself accompanies the executable. #- #-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 under this License. Any attempt #-otherwise to copy, modify, sublicense or distribute the Program is #-void, and will automatically terminate your rights under this License. #-However, parties who have received copies, or rights, from you under #-this License will not have their licenses terminated so long as such #-parties remain in full compliance. #- #- 5. You are not required to accept this License, since you have not #-signed it. However, nothing else grants you permission 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 indicate your acceptance of this License to do so, and #-all its terms and conditions 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 #-Program), 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 the 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 #-infringement 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 conditions of this License, they do not #-excuse you from the conditions of this License. If you cannot #-distribute so as to satisfy simultaneously your obligations under this #-License and any other pertinent 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 you, then #-the only way you could satisfy both it and this License would be to #-refrain entirely from distribution of the Program. #- #-If any portion of this section is held invalid or unenforceable under #-any particular circumstance, the balance of the section is intended to #-apply and the section as a whole is intended to apply in other #-circumstances. #- #-It is not the purpose of this section to induce you to infringe any #-patents or other property right claims or to contest validity of any #-such claims; this section has the sole purpose of protecting the #-integrity of the free software distribution system, which is #-implemented by public license practices. Many people have made #-generous contributions to the wide range of software distributed #-through that system in reliance on consistent application of that #-system; it is up to the author/donor to decide if he or she is willing #-to distribute software through 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 #-certain countries either by patents or by copyrighted interfaces, the #-original copyright holder who places the Program under this 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 version, 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 Program does not specify a version number of #-this License, you may choose any version ever published by the Free Software #-Foundation. #- #- 10. If you wish to incorporate parts of the Program into other free #-programs whose distribution conditions are different, write to the author #-to ask for permission. For software which is copyrighted by the Free #-Software Foundation, write to the Free Software Foundation; we sometimes #-make exceptions for this. Our decision will be guided by the two goals #-of preserving the free status of all derivatives of our free software and #-of promoting the sharing and reuse of software generally. #- #- 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 #-possible use to the public, the best way to achieve this is to make it #-free software which everyone can redistribute and change under these terms. #- #- To do so, attach the following notices to the program. It is safest #-to attach 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) 19yy #- #- 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 of the License, or #- (at your option) any later version. #- #- This program is distributed in the hope that it will be useful, #- but WITHOUT ANY WARRANTY; without even the implied warranty of #- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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 #- `Gnomovision' (which makes passes at compilers) written by James Hacker. #- #- , 1 April 1989 #- Ty Coon, President of Vice #- #-This General Public License does not permit incorporating your program into #-proprietary programs.
