<h3><a name="SEC001">Preamble</a></h3>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>The precise terms and conditions for copying, distribution
|
|
and modification follow.</p>

<h3><a name="SEC002">GNU GENERAL PUBLIC LICENSE TERMS AND
|
|
CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</a></h3>
|
|
|
|
<p>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".</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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:</p>
|
|
|
|
<blockquote>
|
|
a) You must cause the modified files to carry prominent
|
|
notices stating that you changed the files and the date of
|
|
any change.
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.)</p>
|
|
</blockquote>
|
|
<hr>
|
|
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.
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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:</p>
|
|
|
|
<blockquote>
|
|
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,
|
|
|
|
<p>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,</p>
|
|
|
|
<p>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.)</p>
|
|
</blockquote>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
<hr>
|
|
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.
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
<hr>
|
|
This section is intended to make thoroughly clear what is
|
|
believed to be a consequence of the rest of this License.
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<h3><a name="SEC003">NO WARRANTY</a></h3>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
