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 guaran-
tee 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 Soft-
ware 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
Lesser 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 every-
one understands that there is no warranty for this free software. If the software is
modi ed 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
re ect 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 modi cation follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICA-
TION
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 modi cations and/or translated into
another language. (Hereinafter, translation is included without limitation in the
term "modi cation".) Each licensee is addressed as "you".
Activities other than copying, distribution and modi cation 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 modi ca-
tions or work under the terms of Section 1 above, provided that you also meet
all of these conditions:
a) You must cause the modi ed les to carry prominent notices stating that you
changed the les 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 modi ed 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 Pro-
gram 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 modi ed work as a whole. If identi able 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 dis-
tribution 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
modi cations to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface de nition
les, plus the scripts used to control compilation and installation of the executable.
However, as a special exception, the source code distributed need not include any-
thing 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. How-
ever, 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 reli-
ance 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 conse-
quence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries
