Version 3, 29 June 2007 |

Copyright (C) 2007 Free Software Foundation, Inc. https://fsf.org/ |
|
|
|
|
|
|
|
Everyone is permitted to copy and distribute verbatim copies of this |
|
|
|
license document, but changing it is not allowed. |
|
|
|
|
|
|
|
Preamble |
|
|
|
~~~~~~~~ |
|
|
|
|
|
|
|
The GNU General Public License is a free, copyleft license for software |
|
|
|
and other kinds of works. |
|
|
|
|
|
|
|
The licenses for most software and other practical works are designed to |
|
|
|
take away your freedom to share and change the works. By contrast, the |
|
|
|
GNU General Public License is intended to guarantee your freedom to |
|
|
|
share and change all versions of a program–to make sure it remains free |
|
|
|
software for all its users. We, the Free Software Foundation, use the |
|
|
|
GNU General Public License for most of our software; it applies also to |
|
|
|
any other work released this way by its authors. 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 them 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 prevent others from denying you these |
|
|
|
rights or asking you to surrender the rights. Therefore, you have |
|
|
|
certain responsibilities if you distribute copies of the software, or if |
|
|
|
you modify it: responsibilities to respect the freedom of others. |
|
|
|
|
|
|
|
For example, if you distribute copies of such a program, whether gratis |
|
|
|
or for a fee, you must pass on to the recipients the same freedoms that |
|
|
|
you received. 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. |
|
|
|
|
|
|
|
Developers that use the GNU GPL protect your rights with two steps: (1) |
|
|
|
assert copyright on the software, and (2) offer you this License giving |
|
|
|
you legal permission to copy, distribute and/or modify it. |
|
|
|
|
|
|
|
For the developers’ and authors’ protection, the GPL clearly explains |
|
|
|
that there is no warranty for this free software. For both users’ and |
|
|
|
authors’ sake, the GPL requires that modified versions be marked as |
|
|
|
changed, so that their problems will not be attributed erroneously to |
|
|
|
authors of previous versions. |
|
|
|
|
|
|
|
Some devices are designed to deny users access to install or run |
|
|
|
modified versions of the software inside them, although the manufacturer |
|
|
|
can do so. This is fundamentally incompatible with the aim of protecting |
|
|
|
users’ freedom to change the software. The systematic pattern of such |
|
|
|
abuse occurs in the area of products for individuals to use, which is |
|
|
|
precisely where it is most unacceptable. Therefore, we have designed |
|
|
|
this version of the GPL to prohibit the practice for those products. If |
|
|
|
such problems arise substantially in other domains, we stand ready to |
|
|
|
extend this provision to those domains in future versions of the GPL, as |
|
|
|
needed to protect the freedom of users. |
|
|
|
|
|
|
|
Finally, every program is threatened constantly by software patents. |
|
|
|
States should not allow patents to restrict development and use of |
|
|
|
software on general-purpose computers, but in those that do, we wish to |
|
|
|
avoid the special danger that patents applied to a free program could |
|
|
|
make it effectively proprietary. To prevent this, the GPL assures that |
|
|
|
patents cannot be used to render the program non-free. |
|
|
|
|
|
|
|
The precise terms and conditions for copying, distribution and |
|
|
|
modification follow. |

TERMS AND CONDITIONS |
|
|
|
~~~~~~~~~~~~~~~~~~~~ |
|
|
|
|
|
|
|
0. Definitions. |
|
|
|
^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
“This License” refers to version 3 of the GNU General Public License. |
|
|
|
|
|
|
|
“Copyright” also means copyright-like laws that apply to other kinds of |
|
|
|
works, such as semiconductor masks. |
|
|
|
|
|
|
|
“The Program” refers to any copyrightable work licensed under this |
|
|
|
License. Each licensee is addressed as “you”. “Licensees” and |
|
|
|
“recipients” may be individuals or organizations. |
|
|
|
|
|
|
|
To “modify” a work means to copy from or adapt all or part of the work |
|
|
|
in a fashion requiring copyright permission, other than the making of an |
|
|
|
exact copy. The resulting work is called a “modified version” of the |
|
|
|
earlier work or a work “based on” the earlier work. |
|
|
|
|
|
|
|
A “covered work” means either the unmodified Program or a work based on |
|
|
|
the Program. |
|
|
|
|
|
|
|
To “propagate” a work means to do anything with it that, without |
|
|
|
permission, would make you directly or secondarily liable for |
|
|
|
infringement under applicable copyright law, except executing it on a |
|
|
|
computer or modifying a private copy. Propagation includes copying, |
|
|
|
distribution (with or without modification), making available to the |
|
|
|
public, and in some countries other activities as well. |
|
|
|
|
|
|
|
To “convey” a work means any kind of propagation that enables other |
|
|
|
parties to make or receive copies. Mere interaction with a user through |
|
|
|
a computer network, with no transfer of a copy, is not conveying. |
|
|
|
|
|
|
|
An interactive user interface displays “Appropriate Legal Notices” to |
|
|
|
the extent that it includes a convenient and prominently visible feature |
|
|
|
that (1) displays an appropriate copyright notice, and (2) tells the |
|
|
|
user that there is no warranty for the work (except to the extent that |
|
|
|
warranties are provided), that licensees may convey the work under this |
|
|
|
License, and how to view a copy of this License. If the interface |
|
|
|
presents a list of user commands or options, such as a menu, a prominent |
|
|
|
item in the list meets this criterion. |
|
|
|
|
|
|
|
1. Source Code. |
|
|
|
^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
The “source code” for a work means the preferred form of the work for |
|
|
|
making modifications to it. “Object code” means any non-source form of a |
|
|
|
work. |
|
|
|
|
|
|
|
A “Standard Interface” means an interface that either is an official |
|
|
|
standard defined by a recognized standards body, or, in the case of |
|
|
|
interfaces specified for a particular programming language, one that is |
|
|
|
widely used among developers working in that language. |
|
|
|
|
|
|
|
The “System Libraries” of an executable work include anything, other |
|
|
|
than the work as a whole, that (a) is included in the normal form of |
|
|
|
packaging a Major Component, but which is not part of that Major |
|
|
|
Component, and (b) serves only to enable use of the work with that Major |
|
|
|
Component, or to implement a Standard Interface for which an |
|
|
|
implementation is available to the public in source code form. A “Major |
|
|
|
Component”, in this context, means a major essential component (kernel, |
|
|
|
window system, and so on) of the specific operating system (if any) on |
|
|
|
which the executable work runs, or a compiler used to produce the work, |
|
|
|
or an object code interpreter used to run it. |
|
|
|
|
|
|
|
The “Corresponding Source” for a work in object code form means all the |
|
|
|
source code needed to generate, install, and (for an executable work) |
|
|
|
run the object code and to modify the work, including scripts to control |
|
|
|
those activities. However, it does not include the work’s System |
|
|
|
Libraries, or general-purpose tools or generally available free programs |
|
|
|
which are used unmodified in performing those activities but which are |
|
|
|
not part of the work. For example, Corresponding Source includes |
|
|
|
interface definition files associated with source files for the work, |
|
|
|
and the source code for shared libraries and dynamically linked |
|
|
|
subprograms that the work is specifically designed to require, such as |
|
|
|
by intimate data communication or control flow between those subprograms |
|
|
|
and other parts of the work. |
|
|
|
|
|
|
|
The Corresponding Source need not include anything that users can |
|
|
|
regenerate automatically from other parts of the Corresponding Source. |
|
|
|
|
|
|
|
The Corresponding Source for a work in source code form is that same |
|
|
|
work. |
|
|
|
|
|
|
|
2. Basic Permissions. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
All rights granted under this License are granted for the term of |
|
|
|
copyright on the Program, and are irrevocable provided the stated |
|
|
|
conditions are met. This License explicitly affirms your unlimited |
|
|
|
permission to run the unmodified Program. The output from running a |
|
|
|
covered work is covered by this License only if the output, given its |
|
|
|
content, constitutes a covered work. This License acknowledges your |
|
|
|
rights of fair use or other equivalent, as provided by copyright law. |
|
|
|
|
|
|
|
You may make, run and propagate covered works that you do not convey, |
|
|
|
without conditions so long as your license otherwise remains in force. |
|
|
|
You may convey covered works to others for the sole purpose of having |
|
|
|
them make modifications exclusively for you, or provide you with |
|
|
|
facilities for running those works, provided that you comply with the |
|
|
|
terms of this License in conveying all material for which you do not |
|
|
|
control copyright. Those thus making or running the covered works for |
|
|
|
you must do so exclusively on your behalf, under your direction and |
|
|
|
control, on terms that prohibit them from making any copies of your |
|
|
|
copyrighted material outside their relationship with you. |
|
|
|
|
|
|
|
Conveying under any other circumstances is permitted solely under the |
|
|
|
conditions stated below. Sublicensing is not allowed; section 10 makes |
|
|
|
it unnecessary. |
|
|
|
|
|
|
|
3. Protecting Users’ Legal Rights From Anti-Circumvention Law. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
No covered work shall be deemed part of an effective technological |
|
|
|
measure under any applicable law fulfilling obligations under article 11 |
|
|
|
of the WIPO copyright treaty adopted on 20 December 1996, or similar |
|
|
|
laws prohibiting or restricting circumvention of such measures. |
|
|
|
|
|
|
|
When you convey a covered work, you waive any legal power to forbid |
|
|
|
circumvention of technological measures to the extent such circumvention |
|
|
|
is effected by exercising rights under this License with respect to the |
|
|
|
covered work, and you disclaim any intention to limit operation or |
|
|
|
modification of the work as a means of enforcing, against the work’s |
|
|
|
users, your or third parties’ legal rights to forbid circumvention of |
|
|
|
technological measures. |
|
|
|
|
|
|
|
4. Conveying Verbatim Copies. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
You may convey 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; keep |
|
|
|
intact all notices stating that this License and any non-permissive |
|
|
|
terms added in accord with section 7 apply to the code; keep intact all |
|
|
|
notices of the absence of any warranty; and give all recipients a copy |
|
|
|
of this License along with the Program. |
|
|
|
|
|
|
|
You may charge any price or no price for each copy that you convey, and |
|
|
|
you may offer support or warranty protection for a fee. |
|
|
|
|
|
|
|
5. Conveying Modified Source Versions. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
You may convey a work based on the Program, or the modifications to |
|
|
|
produce it from the Program, in the form of source code under the terms |
|
|
|
of section 4, provided that you also meet all of these conditions: |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
a) The work must carry prominent notices stating that you modified |
|
|
|
it, and giving a relevant date. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
b) The work must carry prominent notices stating that it is released |
|
|
|
under this License and any conditions added under section 7. This |
|
|
|
requirement modifies the requirement in section 4 to “keep intact |
|
|
|
all notices”. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
c) You must license the entire work, as a whole, under this License |
|
|
|
to anyone who comes into possession of a copy. This License will |
|
|
|
therefore apply, along with any applicable section 7 additional |
|
|
|
terms, to the whole of the work, and all its parts, regardless of |
|
|
|
how they are packaged. This License gives no permission to license |
|
|
|
the work in any other way, but it does not invalidate such |
|
|
|
permission if you have separately received it. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
d) If the work has interactive user interfaces, each must display |
|
|
|
Appropriate Legal Notices; however, if the Program has interactive |
|
|
|
interfaces that do not display Appropriate Legal Notices, your |
|
|
|
work need not make them do so. |
|
|
|
|
|
|
|
A compilation of a covered work with other separate and independent |
|
|
|
works, which are not by their nature extensions of the covered work, and |
|
|
|
which are not combined with it such as to form a larger program, in or |
|
|
|
on a volume of a storage or distribution medium, is called an |
|
|
|
“aggregate” if the compilation and its resulting copyright are not used |
|
|
|
to limit the access or legal rights of the compilation’s users beyond |
|
|
|
what the individual works permit. Inclusion of a covered work in an |
|
|
|
aggregate does not cause this License to apply to the other parts of the |
|
|
|
aggregate. |
|
|
|
|
|
|
|
6. Conveying Non-Source Forms. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
You may convey a covered work in object code form under the terms of |
|
|
|
sections 4 and 5, provided that you also convey the machine-readable |
|
|
|
Corresponding Source under the terms of this License, in one of these |
|
|
|
ways: |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
a) Convey the object code in, or embodied in, a physical product |
|
|
|
(including a physical distribution medium), accompanied by the |
|
|
|
Corresponding Source fixed on a durable physical medium |
|
|
|
customarily used for software interchange. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
b) Convey the object code in, or embodied in, a physical product |
|
|
|
(including a physical distribution medium), accompanied by a |
|
|
|
written offer, valid for at least three years and valid for as |
|
|
|
long as you offer spare parts or customer support for that product |
|
|
|
model, to give anyone who possesses the object code either (1) a |
|
|
|
copy of the Corresponding Source for all the software in the |
|
|
|
product that is covered by this License, on a durable physical |
|
|
|
medium customarily used for software interchange, for a price no |
|
|
|
more than your reasonable cost of physically performing this |
|
|
|
conveying of source, or (2) access to copy the Corresponding |
|
|
|
Source from a network server at no charge. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
c) Convey individual copies of the object code with a copy of the |
|
|
|
written offer to provide the Corresponding Source. This |
|
|
|
alternative is allowed only occasionally and noncommercially, and |
|
|
|
only if you received the object code with such an offer, in accord |
|
|
|
with subsection 6b. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
d) Convey the object code by offering access from a designated place |
|
|
|
(gratis or for a charge), and offer equivalent access to the |
|
|
|
Corresponding Source in the same way through the same place at no |
|
|
|
further charge. You need not require recipients to copy the |
|
|
|
Corresponding Source along with the object code. If the place to |
|
|
|
copy the object code is a network server, the Corresponding Source |
|
|
|
may be on a different server (operated by you or a third party) |
|
|
|
that supports equivalent copying facilities, provided you maintain |
|
|
|
clear directions next to the object code saying where to find the |
|
|
|
Corresponding Source. Regardless of what server hosts the |
|
|
|
Corresponding Source, you remain obligated to ensure that it is |
|
|
|
available for as long as needed to satisfy these requirements. |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
e) Convey the object code using peer-to-peer transmission, provided |
|
|
|
you inform other peers where the object code and Corresponding |
|
|
|
Source of the work are being offered to the general public at no |
|
|
|
charge under subsection 6d. |
|
|
|
|
|
|
|
A separable portion of the object code, whose source code is excluded |
|
|
|
from the Corresponding Source as a System Library, need not be included |
|
|
|
in conveying the object code work. |
|
|
|
|
|
|
|
A “User Product” is either (1) a “consumer product”, which means any |
|
|
|
tangible personal property which is normally used for personal, family, |
|
|
|
or household purposes, or (2) anything designed or sold for |
|
|
|
incorporation into a dwelling. In determining whether a product is a |
|
|
|
consumer product, doubtful cases shall be resolved in favor of coverage. |
|
|
|
For a particular product received by a particular user, “normally used” |
|
|
|
refers to a typical or common use of that class of product, regardless |
|
|
|
of the status of the particular user or of the way in which the |
|
|
|
particular user actually uses, or expects or is expected to use, the |
|
|
|
product. A product is a consumer product regardless of whether the |
|
|
|
product has substantial commercial, industrial or non-consumer uses, |
|
|
|
unless such uses represent the only significant mode of use of the |
|
|
|
product. |
|
|
|
|
|
|
|
“Installation Information” for a User Product means any methods, |
|
|
|
procedures, authorization keys, or other information required to install |
|
|
|
and execute modified versions of a covered work in that User Product |
|
|
|
from a modified version of its Corresponding Source. The information |
|
|
|
must suffice to ensure that the continued functioning of the modified |
|
|
|
object code is in no case prevented or interfered with solely because |
|
|
|
modification has been made. |
|
|
|
|
|
|
|
If you convey an object code work under this section in, or with, or |
|
|
|
specifically for use in, a User Product, and the conveying occurs as |
|
|
|
part of a transaction in which the right of possession and use of the |
|
|
|
User Product is transferred to the recipient in perpetuity or for a |
|
|
|
fixed term (regardless of how the transaction is characterized), the |
|
|
|
Corresponding Source conveyed under this section must be accompanied by |
|
|
|
the Installation Information. But this requirement does not apply if |
|
|
|
neither you nor any third party retains the ability to install modified |
|
|
|
object code on the User Product (for example, the work has been |
|
|
|
installed in ROM). |
|
|
|
|
|
|
|
The requirement to provide Installation Information does not include a |
|
|
|
requirement to continue to provide support service, warranty, or updates |
|
|
|
for a work that has been modified or installed by the recipient, or for |
|
|
|
the User Product in which it has been modified or installed. Access to a |
|
|
|
network may be denied when the modification itself materially and |
|
|
|
adversely affects the operation of the network or violates the rules and |
|
|
|
protocols for communication across the network. |
|
|
|
|
|
|
|
Corresponding Source conveyed, and Installation Information provided, in |
|
|
|
accord with this section must be in a format that is publicly documented |
|
|
|
(and with an implementation available to the public in source code |
|
|
|
form), and must require no special password or key for unpacking, |
|
|
|
reading or copying. |
|
|
|
|
|
|
|
7. Additional Terms. |
|
|
|
^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
“Additional permissions” are terms that supplement the terms of this |
|
|
|
License by making exceptions from one or more of its conditions. |
|
|
|
Additional permissions that are applicable to the entire Program shall |
|
|
|
be treated as though they were included in this License, to the extent |
|
|
|
that they are valid under applicable law. If additional permissions |
|
|
|
apply only to part of the Program, that part may be used separately |
|
|
|
under those permissions, but the entire Program remains governed by this |
|
|
|
License without regard to the additional permissions. |
|
|
|
|
|
|
|
When you convey a copy of a covered work, you may at your option remove |
|
|
|
any additional permissions from that copy, or from any part of it. |
|
|
|
(Additional permissions may be written to require their own removal in |
|
|
|
certain cases when you modify the work.) You may place additional |
|
|
|
permissions on material, added by you to a covered work, for which you |
|
|
|
have or can give appropriate copyright permission. |
|
|
|
|
|
|
|
Notwithstanding any other provision of this License, for material you |
|
|
|
add to a covered work, you may (if authorized by the copyright holders |
|
|
|
of that material) supplement the terms of this License with terms: |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
a) Disclaiming warranty or limiting liability differently from the |
|
|
|
terms of sections 15 and 16 of this License; or |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
b) Requiring preservation of specified reasonable legal notices or |
|
|
|
author attributions in that material or in the Appropriate Legal |
|
|
|
Notices displayed by works containing it; or |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
c) Prohibiting misrepresentation of the origin of that material, or |
|
|
|
requiring that modified versions of such material be marked in |
|
|
|
reasonable ways as different from the original version; or |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
d) Limiting the use for publicity purposes of names of licensors or |
|
|
|
authors of the material; or |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
e) Declining to grant rights under trademark law for use of some |
|
|
|
trade names, trademarks, or service marks; or |
|
|
|
|
|
|
|
- |
|
|
|
|
|
|
|
f) Requiring indemnification of licensors and authors of that |
|
|
|
material by anyone who conveys the material (or modified versions |
|
|
|
of it) with contractual assumptions of liability to the recipient, |
|
|
|
for any liability that these contractual assumptions directly |
|
|
|
impose on those licensors and authors. |
|
|
|
|
|
|
|
All other non-permissive additional terms are considered “further |
|
|
|
restrictions” within the meaning of section 10. If the Program as you |
|
|
|
received it, or any part of it, contains a notice stating that it is |
|
|
|
governed by this License along with a term that is a further |
|
|
|
restriction, you may remove that term. If a license document contains a |
|
|
|
further restriction but permits relicensing or conveying under this |
|
|
|
License, you may add to a covered work material governed by the terms of |
|
|
|
that license document, provided that the further restriction does not |
|
|
|
survive such relicensing or conveying. |
|
|
|
|
|
|
|
If you add terms to a covered work in accord with this section, you must |
|
|
|
place, in the relevant source files, a statement of the additional terms |
|
|
|
that apply to those files, or a notice indicating where to find the |
|
|
|
applicable terms. |
|
|
|
|
|
|
|
Additional terms, permissive or non-permissive, may be stated in the |
|
|
|
form of a separately written license, or stated as exceptions; the above |
|
|
|
requirements apply either way. |
|
|
|
|
|
|
|
8. Termination. |
|
|
|
^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
You may not propagate or modify a covered work except as expressly |
|
|
|
provided under this License. Any attempt otherwise to propagate or |
|
|
|
modify it is void, and will automatically terminate your rights under |
|
|
|
this License (including any patent licenses granted under the third |
|
|
|
paragraph of section 11). |
|
|
|
|
|
|
|
However, if you cease all violation of this License, then your license |
|
|
|
from a particular copyright holder is reinstated (a) provisionally, |
|
|
|
unless and until the copyright holder explicitly and finally terminates |
|
|
|
your license, and (b) permanently, if the copyright holder fails to |
|
|
|
notify you of the violation by some reasonable means prior to 60 days |
|
|
|
after the cessation. |
|
|
|
|
|
|
|
Moreover, your license from a particular copyright holder is reinstated |
|
|
|
permanently if the copyright holder notifies you of the violation by |
|
|
|
some reasonable means, this is the first time you have received notice |
|
|
|
of violation of this License (for any work) from that copyright holder, |
|
|
|
and you cure the violation prior to 30 days after your receipt of the |
|
|
|
notice. |
|
|
|
|
|
|
|
Termination of your rights under this section does not terminate the |
|
|
|
licenses of parties who have received copies or rights from you under |
|
|
|
this License. If your rights have been terminated and not permanently |
|
|
|
reinstated, you do not qualify to receive new licenses for the same |
|
|
|
material under section 10. |
|
|
|
|
|
|
|
9. Acceptance Not Required for Having Copies. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
You are not required to accept this License in order to receive or run a |
|
|
|
copy of the Program. Ancillary propagation of a covered work occurring |
|
|
|
solely as a consequence of using peer-to-peer transmission to receive a |
|
|
|
copy likewise does not require acceptance. However, nothing other than |
|
|
|
this License grants you permission to propagate or modify any covered |
|
|
|
work. These actions infringe copyright if you do not accept this |
|
|
|
License. Therefore, by modifying or propagating a covered work, you |
|
|
|
indicate your acceptance of this License to do so. |
|
|
|
|
|
|
|
10. Automatic Licensing of Downstream Recipients. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
Each time you convey a covered work, the recipient automatically |
|
|
|
receives a license from the original licensors, to run, modify and |
|
|
|
propagate that work, subject to this License. You are not responsible |
|
|
|
for enforcing compliance by third parties with this License. |
|
|
|
|
|
|
|
An “entity transaction” is a transaction transferring control of an |
|
|
|
organization, or substantially all assets of one, or subdividing an |
|
|
|
organization, or merging organizations. If propagation of a covered work |
|
|
|
results from an entity transaction, each party to that transaction who |
|
|
|
receives a copy of the work also receives whatever licenses to the work |
|
|
|
the party’s predecessor in interest had or could give under the previous |
|
|
|
paragraph, plus a right to possession of the Corresponding Source of the |
|
|
|
work from the predecessor in interest, if the predecessor has it or can |
|
|
|
get it with reasonable efforts. |
|
|
|
|
|
|
|
You may not impose any further restrictions on the exercise of the |
|
|
|
rights granted or affirmed under this License. For example, you may not |
|
|
|
impose a license fee, royalty, or other charge for exercise of rights |
|
|
|
granted under this License, and you may not initiate litigation |
|
|
|
(including a cross-claim or counterclaim in a lawsuit) alleging that any |
|
|
|
patent claim is infringed by making, using, selling, offering for sale, |
|
|
|
or importing the Program or any portion of it. |
|
|
|
|
|
|
|
11. Patents. |
|
|
|
^^^^^^^^^^^^ |
|
|
|
|
|
|
|
A “contributor” is a copyright holder who authorizes use under this |
|
|
|
License of the Program or a work on which the Program is based. The work |
|
|
|
thus licensed is called the contributor’s “contributor version”. |
|
|
|
|
|
|
|
A contributor’s “essential patent claims” are all patent claims owned or |
|
|
|
controlled by the contributor, whether already acquired or hereafter |
|
|
|
acquired, that would be infringed by some manner, permitted by this |
|
|
|
License, of making, using, or selling its contributor version, but do |
|
|
|
not include claims that would be infringed only as a consequence of |
|
|
|
further modification of the contributor version. For purposes of this |
|
|
|
definition, “control” includes the right to grant patent sublicenses in |
|
|
|
a manner consistent with the requirements of this License. |
|
|
|
|
|
|
|
Each contributor grants you a non-exclusive, worldwide, royalty-free |
|
|
|
patent license under the contributor’s essential patent claims, to make, |
|
|
|
use, sell, offer for sale, import and otherwise run, modify and |
|
|
|
propagate the contents of its contributor version. |
|
|
|
|
|
|
|
In the following three paragraphs, a “patent license” is any express |
|
|
|
agreement or commitment, however denominated, not to enforce a patent |
|
|
|
(such as an express permission to practice a patent or covenant not to |
|
|
|
sue for patent infringement). To “grant” such a patent license to a |
|
|
|
party means to make such an agreement or commitment not to enforce a |
|
|
|
patent against the party. |
|
|
|
|
|
|
|
If you convey a covered work, knowingly relying on a patent license, and |
|
|
|
the Corresponding Source of the work is not available for anyone to |
|
|
|
copy, free of charge and under the terms of this License, through a |
|
|
|
publicly available network server or other readily accessible means, |
|
|
|
then you must either (1) cause the Corresponding Source to be so |
|
|
|
available, or (2) arrange to deprive yourself of the benefit of the |
|
|
|
patent license for this particular work, or (3) arrange, in a manner |
|
|
|
consistent with the requirements of this License, to extend the patent |
|
|
|
license to downstream recipients. “Knowingly relying” means you have |
|
|
|
actual knowledge that, but for the patent license, your conveying the |
|
|
|
covered work in a country, or your recipient’s use of the covered work |
|
|
|
in a country, would infringe one or more identifiable patents in that |
|
|
|
country that you have reason to believe are valid. |
|
|
|
|
|
|
|
If, pursuant to or in connection with a single transaction or |
|
|
|
arrangement, you convey, or propagate by procuring conveyance of, a |
|
|
|
covered work, and grant a patent license to some of the parties |
|
|
|
receiving the covered work authorizing them to use, propagate, modify or |
|
|
|
convey a specific copy of the covered work, then the patent license you |
|
|
|
grant is automatically extended to all recipients of the covered work |
|
|
|
and works based on it. |
|
|
|
|
|
|
|
A patent license is “discriminatory” if it does not include within the |
|
|
|
scope of its coverage, prohibits the exercise of, or is conditioned on |
|
|
|
the non-exercise of one or more of the rights that are specifically |
|
|
|
granted under this License. You may not convey a covered work if you are |
|
|
|
a party to an arrangement with a third party that is in the business of |
|
|
|
distributing software, under which you make payment to the third party |
|
|
|
based on the extent of your activity of conveying the work, and under |
|
|
|
which the third party grants, to any of the parties who would receive |
|
|
|
the covered work from you, a discriminatory patent license (a) in |
|
|
|
connection with copies of the covered work conveyed by you (or copies |
|
|
|
made from those copies), or (b) primarily for and in connection with |
|
|
|
specific products or compilations that contain the covered work, unless |
|
|
|
you entered into that arrangement, or that patent license was granted, |
|
|
|
prior to 28 March 2007. |
|
|
|
|
|
|
|
Nothing in this License shall be construed as excluding or limiting any |
|
|
|
implied license or other defenses to infringement that may otherwise be |
|
|
|
available to you under applicable patent law. |
|
|
|
|
|
|
|
12. No Surrender of Others’ Freedom. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
If 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 convey a |
|
|
|
covered work so as to satisfy simultaneously your obligations under this |
|
|
|
License and any other pertinent obligations, then as a consequence you |
|
|
|
may not convey it at all. For example, if you agree to terms that |
|
|
|
obligate you to collect a royalty for further conveying from those to |
|
|
|
whom you convey the Program, the only way you could satisfy both those |
|
|
|
terms and this License would be to refrain entirely from conveying the |
|
|
|
Program. |
|
|
|
|
|
|
|
13. Use with the GNU Affero General Public License. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
Notwithstanding any other provision of this License, you have permission |
|
|
|
to link or combine any covered work with a work licensed under version 3 |
|
|
|
of the GNU Affero General Public License into a single combined work, |
|
|
|
and to convey the resulting work. The terms of this License will |
|
|
|
continue to apply to the part which is the covered work, but the special |
|
|
|
requirements of the GNU Affero General Public License, section 13, |
|
|
|
concerning interaction through a network will apply to the combination |
|
|
|
as such. |
|
|
|
|
|
|
|
14. Revised Versions of this License. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
The Free Software Foundation may publish revised and/or new versions of |
|
|
|
the GNU 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 that a certain numbered version of the GNU General Public |
|
|
|
License “or any later version” applies to it, you have the option of |
|
|
|
following the terms and conditions either of that numbered version or of |
|
|
|
any later version published by the Free Software Foundation. If the |
|
|
|
Program does not specify a version number of the GNU General Public |
|
|
|
License, you may choose any version ever published by the Free Software |
|
|
|
Foundation. |
|
|
|
|
|
|
|
If the Program specifies that a proxy can decide which future versions |
|
|
|
of the GNU General Public License can be used, that proxy’s public |
|
|
|
statement of acceptance of a version permanently authorizes you to |
|
|
|
choose that version for the Program. |
|
|
|
|
|
|
|
Later license versions may give you additional or different permissions. |
|
|
|
However, no additional obligations are imposed on any author or |
|
|
|
copyright holder as a result of your choosing to follow a later version. |
|
|
|
|
|
|
|
15. Disclaimer of Warranty. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
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. |
|
|
|
|
|
|
|
16. Limitation of Liability. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
|
|
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR |
|
|
|
CONVEYS 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. |
|
|
|
|
|
|
|
17. Interpretation of Sections 15 and 16. |
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
|
|
If the disclaimer of warranty and limitation of liability provided above |
|
|
|
cannot be given local legal effect according to their terms, reviewing |
|
|
|
courts shall apply local law that most closely approximates an absolute |
|
|
|
waiver of all civil liability in connection with the Program, unless a |
|
|
|
warranty or assumption of liability accompanies a copy of the Program in |
|
|
|
return for a fee. |
|
|
|
|
|
|
|
END OF TERMS AND CONDITIONS |

|
|
|
|
How to Apply These Terms to Your New Programs |
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
|
|
|
|
|
|
|
If you develop a new program, and you want it to be of the greatest |
|
|
|
possible use to the public, the best way to achieve this is to make it |
|
|
|
free software which everyone can redistribute and change under these |
|
|
|
terms. |
|
|
|
|
|
|
|
To do so, attach the following notices to the program. It is safest to |
|
|
|
attach them to the start of each source file to most effectively state |
|
|
|
the exclusion of warranty; and each file should have at least the |
|
|
|
“copyright” line and a pointer to where the full notice is found. |
|
|
|
|
|
|
|

|
|

|

|
Also add information on how to contact you by electronic and paper mail. |
|
|
|
|
|
|
|
If the program does terminal interaction, make it output a short notice |
|
|
|
like this when it starts in an interactive mode: |

The hypothetical commands \`show w’ and \`show c’ should show the |
|
|

appropriate parts of the General Public License. Of course, your |

|
|
program’s commands might be different; for a GUI interface, you would |
|
|
|
use an “about box”. |
|
|
|
|
|
|
|
You should also get your employer (if you work as a programmer) or |
|
|
|
school, if any, to sign a “copyright disclaimer” for the program, if |
|
|
|
necessary. For more information on this, and how to apply and follow the |

|
|
|
The GNU General Public License does not permit incorporating your |
|
|
|
program into proprietary programs. If your program is a subroutine |
|
|
|
library, you may consider it more useful to permit linking proprietary |
|
|
|
applications with the library. If this is what you want to do, use the |
|
|
|
GNU Lesser General Public License instead of this License. But first, |
