GNU GENERAL PUBLIC LICENSE
 | 
						|
Version 3, 29 June 2007
 | 
						|
 | 
						|
Copyright © 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.
 | 
						|
 | 
						|
     <one line to give the program's name and a brief idea of what it does.>
 | 
						|
     Copyright (C) <year>  <name of author>
 | 
						|
 | 
						|
     This program is free software: you can redistribute it and/or modify it
 | 
						|
under the terms of the GNU General Public License as published by the Free
 | 
						|
Software Foundation, either version 3 of the License, or (at your option) any
 | 
						|
later version.
 | 
						|
 | 
						|
     This program is distributed in the hope that it will be useful, but WITHOUT
 | 
						|
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
 | 
						|
FOR A PARTICULAR PURPOSE.  See the GNU General Public License for more details.
 | 
						|
 | 
						|
     You should have received a copy of the GNU General Public License along
 | 
						|
with this program.  If not, see <https://www.gnu.org/licenses/>.
 | 
						|
 | 
						|
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:
 | 
						|
 | 
						|
     <program>  Copyright (C) <year>  <name of author>
 | 
						|
     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 | 
						|
     This is free software, and you are welcome to redistribute it under certain
 | 
						|
conditions; type `show c' for details.
 | 
						|
 | 
						|
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 GNU GPL, see
 | 
						|
<https://www.gnu.org/licenses/>.
 | 
						|
 | 
						|
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, please read
 | 
						|
<https://www.gnu.org/philosophy/why-not-lgpl.html>.
