GNU GENERAL PUBLIC LICENSE |
Version 2, June 1991 |
Copyright (C) 1989, 1991 Free Software Foundation, Inc. |
59 Temple Place, Suite 330, Boston, MA 02111-1307 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 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. |
<one line to give the program's name and a brief idea of what it does.> |
Copyright (C) <year> <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 |

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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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. |

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 Library General |
Public License instead of this License. |
