675 Mass Ave, Cambridge, MA 02139, 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.

||
