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 thatsame 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 copies of your copy-

righted material outside their relationship with you. Conveying

under any other circumstances is permitted solely under the

conditions stated below. Sublicensing is not allowed; section

10 makes it unnecessary.

3. Protecting Users' Legal Rights From Anti-Circumvention

Law. 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. 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. 4.

Conveying Verbatim Copies. 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
