If the program is interactive, make it output a short notice like this when it

starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision

comes with ABSOLUTELY NO WARRANTY; for details type ‘show w’. This

is free software, and you are welcome to redistribute it under certain

conditions; type ‘show c’ for details.
The hypothetical commands ‘show w’ and ‘show c’ should show the

appropriate parts of the General Public License. Of course, the commands

you use may be called something other than ‘show w’ and ‘show c’; they

could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your

school, if any, to sign a “copyright disclaimer” for the program, if

necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

‘Gnomovision’ (which makes passes at compilers) written by James

Hacker.
signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice This 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.

GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007
Copyright © 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.
