GNU GENERAL PUBLC LCENSE
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 CONDTONS
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 nonsource form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified
for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work
include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation
is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and
so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter
used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or
general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For
example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and
dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of
the Corresponding Source. The Corresponding Source for a work in source code form is that same work.
2.
Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This
License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only
if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright
law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You
may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running
those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or
running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any
