Preamble
|
|
</bridgehead>
|
|
<para>
|
|
The <acronym>GNU</acronym> General Public License is a free, copyleft
|
|
license for software and other kinds of works.
|
|
</para>
|
|
<para>
|
|
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
|
|
<acronym>GNU</acronym> 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 <acronym>GNU</acronym> 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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym>
|
|
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.
|
|
</para>
|
|
<para>
|
|
For the developers’ and authors’ protection, the
|
|
<acronym>GPL</acronym> clearly explains that there is no warranty for this
|
|
free software. For both users’ and authors’ sake, the
|
|
<acronym>GPL</acronym> requires that modified versions be marked as changed,
|
|
so that their problems will not be attributed erroneously to authors of
|
|
previous versions.
|
|
</para>
|
|
<para>
|
|
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
|
|
<acronym>GPL</acronym> 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 <acronym>GPL</acronym>,
|
|
as needed to protect the freedom of users.
|
|
</para>
|
|
<para>
|
|
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 <acronym>GPL</acronym>
|
|
assures that patents cannot be used to render the program non-free.

<bridgehead renderas="sect1">

0. Definitions.
|
|
</bridgehead>
|
|
<para>
|
|
“This License” refers to version 3 of the <acronym>GNU</acronym>
|
|
General Public License.
|
|
</para>
|
|
<para>
|
|
“Copyright” also means copyright-like laws that apply to other
|
|
kinds of works, such as semiconductor masks.
|
|
</para>
|
|
<para>
|
|
“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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
A “covered work” means either the unmodified Program or a work
|
|
based on the Program.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<bridgehead renderas="sect1">
|
|
1. Source Code.
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
The Corresponding Source need not include anything that users can regenerate
|
|
automatically from other parts of the Corresponding Source.
|
|
</para>
|
|
<para>
|
|
The Corresponding Source for a work in source code form is that same work.
|
|
</para>
|
|
<bridgehead renderas="sect1">
|
|
2. Basic Permissions.
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
Conveying under any other circumstances is permitted solely under the
|
|
conditions stated below. Sublicensing is not allowed; section 10 makes it
|
|
unnecessary.
|
|
</para>
|
|
<bridgehead renderas="sect1">
|
|
3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<bridgehead renderas="sect1">
|
|
4. Conveying Verbatim Copies.
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<bridgehead renderas="sect1">
|
|
5. Conveying Modified Source Versions.
|
|
</bridgehead>
|
|
<para>
|
|
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:
|
|
</para>
|
|
<orderedlist numeration="loweralpha">
|
|
<listitem>
|

giving a relevant date.

</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
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”.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
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.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
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.
|
|
</para>

</listitem>
|

</orderedlist>
|
|
<para>
|
|
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.

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

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

Convey the object code by offering access from a designated place

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.

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.
|
|
</para>
|
|
<para>
|
|
“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.

</para>

<para>
|

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
|
|
<acronym>ROM</acronym>).

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

|
|
copying.

7. Additional Terms.

</bridgehead>
|
|
<para>
|
|
“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.
|
|
</para>
|
|
<para>
|
|
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.

All other non-permissive additional terms are considered “further

restrictions” within the meaning of section 10. If the Program as

|
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.

You may not propagate or modify a covered work except as expressly provided

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

|
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.

Each time you convey a covered work, the recipient automatically receives a

license from the original licensors, to run, modify and propagate that

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.

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

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.

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,

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.

If conditions are imposed on you (whether by court order, agreement or

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.

If you develop a new program, and you want it to be of the greatest possible

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

“copyright” line and a pointer to where the full notice is
