PREAMBLE |
||||
|
||||
The purpose of this License is to make a manual, textbook, or other |
||||
functional and useful document @dfn{free} in the sense of freedom: to |
||||
assure everyone the effective freedom to copy and redistribute it, |
||||
with or without modifying it, either commercially or noncommercially. |
||||
Secondarily, this License preserves for the author and publisher a way |
||||
to get credit for their work, while not being considered responsible |
||||
for modifications made by others. |
||||
|
||||
This License is a kind of ``copyleft'', which means that derivative |
||||
works of the document must themselves be free in the same sense. It |
||||
complements the GNU General Public License, which is a copyleft |
||||
license designed for free software. |
||||
|
||||
We have designed this License in order to use it for manuals for free |
||||
software, because free software needs free documentation: a free |
||||
program should come with manuals providing the same freedoms that the |
||||
software does. But this License is not limited to software manuals; |
||||
it can be used for any textual work, regardless of subject matter or |
||||
whether it is published as a printed book. We recommend this License |
||||
principally for works whose purpose is instruction or reference. |
||||
|
||||
@item |
||||
APPLICABILITY AND DEFINITIONS |
||||
|
||||
This License applies to any manual or other work, in any medium, that |
||||
contains a notice placed by the copyright holder saying it can be |
||||
distributed under the terms of this License. Such a notice grants a |
||||
world-wide, royalty-free license, unlimited in duration, to use that |
||||
work under the conditions stated herein. The ``Document'', below, |
||||
refers to any such manual or work. Any member of the public is a |
||||
licensee, and is addressed as ``you''. You accept the license if you |
||||
copy, modify or distribute the work in a way requiring permission |
||||
under copyright law. |
||||
|
||||
A ``Modified Version'' of the Document means any work containing the |
||||
Document or a portion of it, either copied verbatim, or with |
||||
modifications and/or translated into another language. |
||||
|
||||
A ``Secondary Section'' is a named appendix or a front-matter section |
||||
of the Document that deals exclusively with the relationship of the |
||||
publishers or authors of the Document to the Document's overall |
||||
subject (or to related matters) and contains nothing that could fall |
||||
directly within that overall subject. (Thus, if the Document is in |
||||
part a textbook of mathematics, a Secondary Section may not explain |
||||
any mathematics.) The relationship could be a matter of historical |
||||
connection with the subject or with related matters, or of legal, |
||||
commercial, philosophical, ethical or political position regarding |
||||
them. |
||||
|
||||
The ``Invariant Sections'' are certain Secondary Sections whose titles |
||||
are designated, as being those of Invariant Sections, in the notice |
||||
that says that the Document is released under this License. If a |
||||
section does not fit the above definition of Secondary then it is not |
||||
allowed to be designated as Invariant. The Document may contain zero |
||||
Invariant Sections. If the Document does not identify any Invariant |
||||
Sections then there are none. |
||||
|
||||
The ``Cover Texts'' are certain short passages of text that are listed, |
||||
as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
||||
the Document is released under this License. A Front-Cover Text may |
||||
be at most 5 words, and a Back-Cover Text may be at most 25 words. |
||||
|
||||
A ``Transparent'' copy of the Document means a machine-readable copy, |
||||
represented in a format whose specification is available to the |
||||
general public, that is suitable for revising the document |
||||
straightforwardly with generic text editors or (for images composed of |
||||
pixels) generic paint programs or (for drawings) some widely available |
||||
drawing editor, and that is suitable for input to text formatters or |
||||
for automatic translation to a variety of formats suitable for input |
||||
to text formatters. A copy made in an otherwise Transparent file |
||||
format whose markup, or absence of markup, has been arranged to thwart |
||||
or discourage subsequent modification by readers is not Transparent. |
||||
An image format is not Transparent if used for any substantial amount |
||||
of text. A copy that is not ``Transparent'' is called ``Opaque''. |
||||
|
||||
Examples of suitable formats for Transparent copies include plain |
||||
ASCII without markup, Texinfo input format, La@TeX{} input |
||||
format, SGML or XML using a publicly available |
||||
DTD, and standard-conforming simple HTML, |
||||
PostScript or PDF designed for human modification. Examples |
||||
of transparent image formats include PNG, XCF and |
||||
JPG@. Opaque formats include proprietary formats that can be |
||||
read and edited only by proprietary word processors, SGML or |
||||
XML for which the DTD and/or processing tools are |
||||
not generally available, and the machine-generated HTML, |
||||
PostScript or PDF produced by some word processors for |
||||
output purposes only. |
||||
|
||||
The ``Title Page'' means, for a printed book, the title page itself, |
||||
plus such following pages as are needed to hold, legibly, the material |
||||
this License requires to appear in the title page. For works in |
||||
formats which do not have any title page as such, ``Title Page'' means |
||||
the text near the most prominent appearance of the work's title, |
||||
preceding the beginning of the body of the text. |
||||
|
||||
The ``publisher'' means any person or entity that distributes copies |
||||
of the Document to the public. |
||||
|
||||
A section ``Entitled XYZ'' means a named subunit of the Document whose |
||||
title either is precisely XYZ or contains XYZ in parentheses following |
||||
text that translates XYZ in another language. (Here XYZ stands for a |
||||
specific section name mentioned below, such as ``Acknowledgements'', |
||||
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' |
||||
of such a section when you modify the Document means that it remains a |
||||
section ``Entitled XYZ'' according to this definition. |
||||
|
||||
The Document may include Warranty Disclaimers next to the notice which |
||||
states that this License applies to the Document. These Warranty |
||||
Disclaimers are considered to be included by reference in this |
||||
License, but only as regards disclaiming warranties: any other |
||||
implication that these Warranty Disclaimers may have is void and has |
||||
no effect on the meaning of this License. |
||||
|
||||
@item |
||||
VERBATIM COPYING |
||||
|
||||
You may copy and distribute the Document in any medium, either |
||||
commercially or noncommercially, provided that this License, the |
||||
copyright notices, and the license notice saying this License applies |
||||
to the Document are reproduced in all copies, and that you add no other |
||||
conditions whatsoever to those of this License. You may not use |
||||
technical measures to obstruct or control the reading or further |
||||
copying of the copies you make or distribute. However, you may accept |
||||
compensation in exchange for copies. If you distribute a large enough |
||||
number of copies you must also follow the conditions in section 3. |
||||
|
||||
You may also lend copies, under the same conditions stated above, and |
||||
you may publicly display copies. |
||||
|
||||
@item |
||||
COPYING IN QUANTITY |
||||
|
||||
If you publish printed copies (or copies in media that commonly have |
||||
printed covers) of the Document, numbering more than 100, and the |
||||
Document's license notice requires Cover Texts, you must enclose the |
||||
copies in covers that carry, clearly and legibly, all these Cover |
||||
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
||||
the back cover. Both covers must also clearly and legibly identify |
||||
you as the publisher of these copies. The front cover must present |
||||
the full title with all words of the title equally prominent and |
||||
visible. You may add other material on the covers in addition. |
||||
Copying with changes limited to the covers, as long as they preserve |
||||
the title of the Document and satisfy these conditions, can be treated |
||||
as verbatim copying in other respects. |
||||
|
||||
If the required texts for either cover are too voluminous to fit |
||||
legibly, you should put the first ones listed (as many as fit |
||||
reasonably) on the actual cover, and continue the rest onto adjacent |
||||
pages. |
||||
|
||||
If you publish or distribute Opaque copies of the Document numbering |
||||
more than 100, you must either include a machine-readable Transparent |
||||
copy along with each Opaque copy, or state in or with each Opaque copy |
||||
a computer-network location from which the general network-using |
||||
public has access to download using public-standard network protocols |
||||
a complete Transparent copy of the Document, free of added material. |
||||
If you use the latter option, you must take reasonably prudent steps, |
||||
when you begin distribution of Opaque copies in quantity, to ensure |
||||
that this Transparent copy will remain thus accessible at the stated |
||||
location until at least one year after the last time you distribute an |
||||
Opaque copy (directly or through your agents or retailers) of that |
||||
edition to the public. |
||||
|
||||
It is requested, but not required, that you contact the authors of the |
||||
Document well before redistributing any large number of copies, to give |
||||
them a chance to provide you with an updated version of the Document. |
||||
|
||||
@item |
||||
MODIFICATIONS |
||||
|
||||
You may copy and distribute a Modified Version of the Document under |
||||
the conditions of sections 2 and 3 above, provided that you release |
||||
the Modified Version under precisely this License, with the Modified |
||||
Version filling the role of the Document, thus licensing distribution |
||||
and modification of the Modified Version to whoever possesses a copy |
||||
of it. In addition, you must do these things in the Modified Version: |
||||
|
||||
@enumerate A |
||||
@item |
||||
Use in the Title Page (and on the covers, if any) a title distinct |
||||
from that of the Document, and from those of previous versions |
||||
(which should, if there were any, be listed in the History section |
||||
of the Document). You may use the same title as a previous version |
||||
if the original publisher of that version gives permission. |
||||
|
||||
@item |
||||
List on the Title Page, as authors, one or more persons or entities |
||||
responsible for authorship of the modifications in the Modified |
||||
Version, together with at least five of the principal authors of the |
||||
Document (all of its principal authors, if it has fewer than five), |
||||
unless they release you from this requirement. |
||||
|
||||
@item |
||||
State on the Title page the name of the publisher of the |
||||
Modified Version, as the publisher. |
||||
|
||||
@item |
||||
Preserve all the copyright notices of the Document. |
||||
|
||||
@item |
||||
Add an appropriate copyright notice for your modifications |
||||
adjacent to the other copyright notices. |
||||
|
||||
@item |
||||
Include, immediately after the copyright notices, a license notice |
||||
giving the public permission to use the Modified Version under the |
||||
terms of this License, in the form shown in the Addendum below. |
||||
|
||||
@item |
||||
Preserve in that license notice the full lists of Invariant Sections |
||||
and required Cover Texts given in the Document's license notice. |
||||
|
||||
@item |
||||
Include an unaltered copy of this License. |
||||
|
||||
@item |
||||
Preserve the section Entitled ``History'', Preserve its Title, and add |
||||
to it an item stating at least the title, year, new authors, and |
||||
publisher of the Modified Version as given on the Title Page. If |
||||
there is no section Entitled ``History'' in the Document, create one |
||||
stating the title, year, authors, and publisher of the Document as |
||||
given on its Title Page, then add an item describing the Modified |
||||
Version as stated in the previous sentence. |
||||
|
||||
@item |
||||
Preserve the network location, if any, given in the Document for |
||||
public access to a Transparent copy of the Document, and likewise |
||||
the network locations given in the Document for previous versions |
||||
it was based on. These may be placed in the ``History'' section. |
||||
You may omit a network location for a work that was published at |
||||
least four years before the Document itself, or if the original |
||||
publisher of the version it refers to gives permission. |
||||
|
||||
@item |
||||
For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve |
||||
the Title of the section, and preserve in the section all the |
||||
substance and tone of each of the contributor acknowledgements and/or |
||||
dedications given therein. |
||||
|
||||
@item |
||||
Preserve all the Invariant Sections of the Document, |
||||
unaltered in their text and in their titles. Section numbers |
||||
or the equivalent are not considered part of the section titles. |
||||
|
||||
@item |
||||
Delete any section Entitled ``Endorsements''. Such a section |
||||
may not be included in the Modified Version. |
||||
|
||||
@item |
||||
Do not retitle any existing section to be Entitled ``Endorsements'' or |
||||
to conflict in title with any Invariant Section. |
||||
|
||||
@item |
||||
Preserve any Warranty Disclaimers. |
||||
@end enumerate |
||||
|
||||
If the Modified Version includes new front-matter sections or |
||||
appendices that qualify as Secondary Sections and contain no material |
||||
copied from the Document, you may at your option designate some or all |
||||
of these sections as invariant. To do this, add their titles to the |
||||
list of Invariant Sections in the Modified Version's license notice. |
||||
These titles must be distinct from any other section titles. |
||||
|
||||
You may add a section Entitled ``Endorsements'', provided it contains |
||||
nothing but endorsements of your Modified Version by various |
||||
parties---for example, statements of peer review or that the text has |
||||
been approved by an organization as the authoritative definition of a |
||||
standard. |
||||
|
||||
You may add a passage of up to five words as a Front-Cover Text, and a |
||||
passage of up to 25 words as a Back-Cover Text, to the end of the list |
||||
of Cover Texts in the Modified Version. Only one passage of |
||||
Front-Cover Text and one of Back-Cover Text may be added by (or |
||||
through arrangements made by) any one entity. If the Document already |
||||
includes a cover text for the same cover, previously added by you or |
||||
by arrangement made by the same entity you are acting on behalf of, |
||||
you may not add another; but you may replace the old one, on explicit |
||||
permission from the previous publisher that added the old one. |
||||
|
||||
The author(s) and publisher(s) of the Document do not by this License |
||||
give permission to use their names for publicity for or to assert or |
||||
imply endorsement of any Modified Version. |
||||
|
||||
@item |
||||
COMBINING DOCUMENTS |
||||
|
||||
You may combine the Document with other documents released under this |
||||
License, under the terms defined in section 4 above for modified |
||||
versions, provided that you include in the combination all of the |
||||
Invariant Sections of all of the original documents, unmodified, and |
||||
list them all as Invariant Sections of your combined work in its |
||||
license notice, and that you preserve all their Warranty Disclaimers. |
||||
|
||||
The combined work need only contain one copy of this License, and |
||||
multiple identical Invariant Sections may be replaced with a single |
||||
copy. If there are multiple Invariant Sections with the same name but |
||||
different contents, make the title of each such section unique by |
||||
adding at the end of it, in parentheses, the name of the original |
||||
author or publisher of that section if known, or else a unique number. |
||||
Make the same adjustment to the section titles in the list of |
||||
Invariant Sections in the license notice of the combined work. |
||||
|
||||
In the combination, you must combine any sections Entitled ``History'' |
||||
in the various original documents, forming one section Entitled |
||||
``History''; likewise combine any sections Entitled ``Acknowledgements'', |
||||
and any sections Entitled ``Dedications''. You must delete all |
||||
sections Entitled ``Endorsements.'' |
||||
|
||||
@item |
||||
COLLECTIONS OF DOCUMENTS |
||||
|
||||
You may make a collection consisting of the Document and other documents |
||||
released under this License, and replace the individual copies of this |
||||
License in the various documents with a single copy that is included in |
||||
the collection, provided that you follow the rules of this License for |
||||
verbatim copying of each of the documents in all other respects. |
||||
|
||||
You may extract a single document from such a collection, and distribute |
||||
it individually under this License, provided you insert a copy of this |
||||
License into the extracted document, and follow this License in all |
||||
other respects regarding verbatim copying of that document. |
||||
|
||||
@item |
||||
AGGREGATION WITH INDEPENDENT WORKS |
||||
|
||||
A compilation of the Document or its derivatives with other separate |
||||
and independent documents or works, in or on a volume of a storage or |
||||
distribution medium, is called an ``aggregate'' if the copyright |
||||
resulting from the compilation is not used to limit the legal rights |
||||
of the compilation's users beyond what the individual works permit. |
||||
When the Document is included in an aggregate, this License does not |
||||
apply to the other works in the aggregate which are not themselves |
||||
derivative works of the Document. |
||||
|
||||
If the Cover Text requirement of section 3 is applicable to these |
||||
copies of the Document, then if the Document is less than one half of |
||||
the entire aggregate, the Document's Cover Texts may be placed on |
||||
covers that bracket the Document within the aggregate, or the |
||||
electronic equivalent of covers if the Document is in electronic form. |
||||
Otherwise they must appear on printed covers that bracket the whole |
||||
aggregate. |
||||
|
||||
@item |
||||
TRANSLATION |
||||
|
||||
Translation is considered a kind of modification, so you may |
||||
distribute translations of the Document under the terms of section 4. |
||||
Replacing Invariant Sections with translations requires special |
||||
permission from their copyright holders, but you may include |
||||
translations of some or all Invariant Sections in addition to the |
||||
original versions of these Invariant Sections. You may include a |
||||
translation of this License, and all the license notices in the |
||||
Document, and any Warranty Disclaimers, provided that you also include |
||||
the original English version of this License and the original versions |
||||
of those notices and disclaimers. In case of a disagreement between |
||||
the translation and the original version of this License or a notice |
||||
or disclaimer, the original version will prevail. |
||||
|
||||
If a section in the Document is Entitled ``Acknowledgements'', |
||||
``Dedications'', or ``History'', the requirement (section 4) to Preserve |
||||
its Title (section 1) will typically require changing the actual |
||||
title. |
||||
|
||||
@item |
||||
TERMINATION |
||||
|
||||
You may not copy, modify, sublicense, or distribute the Document |
||||
except as expressly provided under this License. Any attempt |
||||
otherwise to copy, modify, sublicense, or distribute it is void, and |
||||
will automatically terminate your rights under this License. |
||||
|
||||
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, receipt of a copy of some or all of the same material does |
||||
not give you any rights to use it. |
||||
|
||||
@item |
||||
FUTURE REVISIONS OF THIS LICENSE |
||||
|
||||
The Free Software Foundation may publish new, revised versions |
||||
of the GNU Free Documentation 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. See |
||||
@uref{https://www.gnu.org/licenses/}. |
||||
|
||||
Each version of the License is given a distinguishing version number. |
||||
If the Document specifies that a particular numbered version of this |
||||
License ``or any later version'' applies to it, you have the option of |
||||
following the terms and conditions either of that specified version or |
||||
of any later version that has been published (not as a draft) by the |
||||
Free Software Foundation. If the Document does not specify a version |
||||
number of this License, you may choose any version ever published (not |
||||
as a draft) by the Free Software Foundation. If the Document |
||||
specifies that a proxy can decide which future versions of this |
||||
License can be used, that proxy's public statement of acceptance of a |
||||
version permanently authorizes you to choose that version for the |
||||
Document. |
||||
|
||||
@item |
||||
RELICENSING |
||||
|
||||
``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any |
||||
World Wide Web server that publishes copyrightable works and also |
||||
provides prominent facilities for anybody to edit those works. A |
||||
public wiki that anybody can edit is an example of such a server. A |
||||
``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the |
||||
site means any set of copyrightable works thus published on the MMC |
||||
site. |
||||
|
||||
``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0 |
||||
license published by Creative Commons Corporation, a not-for-profit |
||||
corporation with a principal place of business in San Francisco, |
||||
California, as well as future copyleft versions of that license |
||||
published by that same organization. |
||||
|
||||
``Incorporate'' means to publish or republish a Document, in whole or |
||||
in part, as part of another Document. |
||||
|
||||
An MMC is ``eligible for relicensing'' if it is licensed under this |
||||
License, and if all works that were first published under this License |
||||
somewhere other than this MMC, and subsequently incorporated in whole |
||||
or in part into the MMC, (1) had no cover texts or invariant sections, |
||||
and (2) were thus incorporated prior to November 1, 2008. |
||||
|
||||
The operator of an MMC Site may republish an MMC contained in the site |
||||
under CC-BY-SA on the same site at any time before August 1, 2009, |
||||
provided the MMC is eligible for relicensing. |

Everyone is permitted to copy and distribute verbatim copies of this |

license document, but changing it is not allowed. |

@end display |

|

@heading 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. |
||||
|
||||
@heading TERMS AND CONDITIONS |
||||
|
||||
@enumerate 0 |
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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: |
||||
|
||||
@enumerate a |
||||
@item |
||||
The work must carry prominent notices stating that you modified it, |
||||
and giving a relevant date. |
||||
|
||||
@item |
||||
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''. |
||||
|
||||
@item |
||||
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. |
||||
|
||||
@item |
||||
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. |
||||
@end enumerate |
||||
|
||||
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. |
||||
|
||||
@item 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: |
||||
|
||||
@enumerate a |
||||
@item |
||||
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. |
||||
|
||||
@item |
||||
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. |
||||
|
||||
@item |
||||
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. |
||||
|
||||
@item |
||||
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. |
||||
|
||||
@item |
||||
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. |
||||
|
||||
@end enumerate |
||||
|
||||
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. |
||||
|
||||
@item 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: |
||||
|
||||
@enumerate a |
||||
@item |
||||
Disclaiming warranty or limiting liability differently from the terms |
||||
of sections 15 and 16 of this License; or |
||||
|
||||
@item |
||||
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 |
||||
|
||||
@item |
||||
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 |
||||
|
||||
@item |
||||
Limiting the use for publicity purposes of names of licensors or |
||||
authors of the material; or |
||||
|
||||
@item |
||||
Declining to grant rights under trademark law for use of some trade |
||||
names, trademarks, or service marks; or |
||||
|
||||
@item |
||||
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. |
||||
@end enumerate |
||||
|
||||
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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||
|
||||
@item 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. |
||||

@heading 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. |
||||

||||

|
||||
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 @url{https://www.gnu.org/licenses/}. |
||||
@end smallexample |
||||
|
||||
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: |
||||
|
||||
@smallexample |
||||
@var{program} Copyright (C) @var{year} @var{name of author} |
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}. |
||||
This is free software, and you are welcome to redistribute it |
||||
under certain conditions; type @samp{show c} for details. |
||||
@end smallexample |
||||
|
||||
The hypothetical commands @samp{show w} and @samp{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 @url{https://www.gnu.org/licenses/why-not-lgpl.html}. |
