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
END OF TERMS AND CONDITIONS
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.
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
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.
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:
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.
You must cause the modified files to carry
prominent notices stating that you changed the files and the date of any
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.
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.)
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.
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:
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.
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;
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;
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.)
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.
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.
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.
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.
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
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.
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.
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.
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.
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.
