Everyone is permitted to copy and distribute verbatim copies

of this license document, but changing it is not allowed.

|
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.
