The Star Traders game is free software that is distributed under the terms
|
|
of the GNU General Public License. The actual copyright on this program
|
|
("the Program", in the language of the License) belongs to John Zaitseff,
|
|
although the text of the License itself belongs to the Free Software
|
|
Foundation.
|
|
|
|
Even though the GNU General Public License does NOT require you to send
|
|
your modifications back to the author, it is considered "good form" to do
|
|
so, as this allows your modifications to be incorporated into future
|
|
versions of the program, allowing others to benefit from them.

GNU GENERAL PUBLIC LICENSE
|
|
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.
|
|
|
|
<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.

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
