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.
