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. 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.
|
||||
|
||||
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.
|
||||
|
||||
<one line to give the program's name and an idea of what it does.>
|
||||
|
||||
Copyright (C) <yyyy> <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 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. 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., 51 Franklin
|
||||
Street, Fifth Floor, Boston, MA 02110-1301, 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) year 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
|
||||
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.
|
||||
|
||||
<signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General
|
||||
Public License does not permit incorporating your program into proprietary
|
||||
programs. If your program is a subroutine library, you may consider it more
|
||||
useful to permit linking proprietary applications with the library. If this
|
||||
is what you want to do, use the GNU Lesser General Public License instead
|
||||
of this License.
