- GNU GENERAL PUBLIC LICENSE
-
- Version 1, February 1989
-
- Copyright (C) 1989 Free Software Foundation, Inc. 51 Franklin St, 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 license agreements of most software companies try to keep users at the
- mercy of those companies. By contrast, our 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. The General Public License applies
- to the Free Software Foundation's software and to any other program whose
- authors commit to using it. You can use it for your programs, too.
-
- When we speak of free software, we are referring to freedom, not price. Specifically,
- the General Public License is designed to make sure that you have the freedom
- to give away or sell copies of free software, 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 a 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 tell them 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.
-
- 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 Agreement 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 work containing the Program or a portion of it, either verbatim
- or with modifications. Each licensee is addressed as "you".
-
-
-
- 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 General Public License and
- to the absence of any warranty; and give any other recipients of the Program
- a copy of this General Public License along with the Program. You may charge
- a fee for the physical act of transferring a copy.
-
-
-
- 2. You may modify your copy or copies of the Program or any portion of it,
- and copy and distribute such modifications under the terms of Paragraph 1
- above, provided that you also do the following:
-
- a) cause the modified files to carry prominent notices stating that you changed
- the files and the date of any change; and
-
- b) cause the whole of any work that you distribute or publish, that in whole
- or in part contains the Program or any part thereof, either with or without
- modifications, to be licensed at no charge to all third parties under the
- terms of this General Public License (except that you may choose to grant
- warranty protection to some or all third parties, at your option).
-
- c) If the modified program normally reads commands interactively when run,
- you must cause it, when started running for such interactive use in the simplest
- and most usual 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 General
- Public License.
-
- d) 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.
-
- Mere aggregation of another independent work with the Program (or its derivative)
- on a volume of a storage or distribution medium does not bring the other work
- under the scope of these terms.
-
-
-
- 3. You may copy and distribute the Program (or a portion or derivative of
- it, under Paragraph 2) in object code or executable form under the terms of
- Paragraphs 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 Paragraphs 1 and 2 above; or,
-
- b) accompany it with a written offer, valid for at least three years, to give
- any third party free (except for a nominal charge for the cost of distribution)
- a complete machine-readable copy of the corresponding source code, to be distributed
- under the terms of Paragraphs 1 and 2 above; or,
-
- c) accompany it with the information you received as to where the corresponding
- source code may be obtained. (This alternative is allowed only for noncommercial
- distribution and only if you received the program in object code or executable
- form alone.)
-
- Source code for a work means the preferred form of the work for making modifications
- to it. For an executable file, complete source code means all the source code
- for all modules it contains; but, as a special exception, it need not include
- source code for modules which are standard libraries that accompany the operating
- system on which the executable file runs, or for standard header files or
- definitions files that accompany that operating system.
-
-
-
- 4. You may not copy, modify, sublicense, distribute or transfer the Program
- except as expressly provided under this General Public License. Any attempt
- otherwise to copy, modify, sublicense, distribute or transfer the Program
- is void, and will automatically terminate your rights to use the Program under
- this License. However, parties who have received copies, or rights to use
- copies, from you under this General Public License will not have their licenses
- terminated so long as such parties remain in full compliance.
-
-
-
- 5. By copying, distributing or modifying 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.
-
-
-
- 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.
-
-
-
- 7. 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 the 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 the license, you may choose any
- version ever published by the Free Software Foundation.
-
-
-
- 8. 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
-
- 9. 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.
-
-
-
- 10. 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
-
- Appendix: 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 humanity, 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.
-
- <one line to give the program's name and a brief idea of what it does.> Copyright
- (C) 19yy <name of author>
-
- 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 1, 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. See the GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License along with
- this program; if not, write to the Free Software Foundation, Inc., 675 Mass
- Ave, Cambridge, MA 02139, USA.
-
- Also add information on how to contact you by electronic and paper mail.
-
- If the program is interactive, make it output a short notice like this when
- it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19xx name of author Gnomovision comes
- with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software,
- and you are welcome to redistribute it under certain conditions; type `show
- c' for details.
-
- The hypothetical commands `show w' and `show c' should show the appropriate
- parts of the General Public License. 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
- a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'
- (a program to direct compilers to make passes at assemblers) written by James
- Hacker.
-
- <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice
-
- That's all there is to it!
