GNU General public license, version 3

----------------------------------------
GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://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.
