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 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 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+ 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 license 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.
