GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing

it is not allowed.
Preamble

The licenses for most software are designed to take away your freedom to share and change it.

By contrast, the GNU General Public License is intended to guarantee your freedom to share and

change free software--to make sure the software is free for all its users. This General Public License

applies to most of the Free Software Foundation’s software and to any other program whose

authors commit to using it. (Some other Free Software Foundation software is covered by the

GNU Lesser General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny you these rights or

to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if

you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give

the recipients all the rights that you have. 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.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license

which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author’s protection and ours, we want to make certain that everyone understands

that there is no warranty for this free software. If the software is modified by someone else and

passed on, we want its recipients to know that what they have is not the original, so that any

problems introduced by others will not reflect on the original authors’ reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger

that redistributors of a free program will individually obtain patent licenses, in effect making the

program proprietary. To prevent this, we have made it clear that any patent must be licensed for

everyone’s free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND

MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the

The “Program”, below, refers to any such program or work, and a “work based on the Program”

means either the Program or any derivative work under copyright law: that is to say, a work

containing the Program or a portion of it, either verbatim or with modifications and/or translated

into another language. (Hereinafter, translation is included without limitation in the term

“modification”.) Each licensee is addressed as “you”.

Activities other than copying, distribution and modification are not covered by this License; they

are outside its scope. The act of running the Program is not restricted, and the output from the

Program is covered only if its contents constitute a work based on the Program (independent

of having been made by running the Program). Whether that is true depends on what the

Program does.

1. You may copy and distribute verbatim copies of the Program’s source code as you receive it,

in any medium, provided that you conspicuously and appropriately publish on each copy an

appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to

this License and to the absence of any warranty; and give any other recipients of the Program a

copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer

warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work

based on the Program, and copy and distribute such modifications or work under the terms of

Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files

and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is

derived from the Program or any part thereof, to be licensed as a whole at no charge to all

third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you must cause it,

when started running for such interactive use in the most ordinary way, to print or display an

announcement including an appropriate copyright notice and a notice that there is no warranty

(or else, saying that you provide a warranty) and that users may redistribute the program

under these conditions, and telling the user how to view a copy of this License. (Exception: if

the Program itself is interactive but does not normally print such an announcement, your work

based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work

are not derived from the Program, and can be reasonably considered independent and separate

works in themselves, then this License, and its terms, do not apply to those sections when you

distribute them as separate works. But when you distribute the same sections as part of a whole

which is a work based on the Program, the distribution of the whole must be on the terms of

this License, whose permissions for other licensees extend to the entire whole, and thus to each

and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written

entirely by you; rather, the intent is to exercise the right to control the distribution of derivative

or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or

with a work based on the Program) on a volume of a storage or distribution medium does not

bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object

code or executable form under the terms of Sections 1 and 2 above provided that you also do

one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must

be distributed under the terms of Sections 1 and 2 above on a medium customarily used for

software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a

charge no more than your cost of physically performing source distribution, a complete machine-

readable copy of the corresponding source code, to be distributed under the terms of Sections

1 and 2 above on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding

source code. (This alternative is allowed only for noncommercial distribution and only if you

received the program in object code or executable form with such an offer, in accord with

Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to

it. For an executable work, complete source code means all the source code for all modules it

contains, plus any associated interface definition files, plus the scripts used to control compilation

and installation of the executable. However, as a special exception, the source code distributed

need not include anything that is normally distributed (in either source or binary form) with

the major components (compiler, kernel, and so on) of the operating system on which the

executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated

place, then offering equivalent access to copy the source code from the same place counts as

distribution of the source code, even though third parties are not compelled to copy the source

along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided

under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is

void, and will automatically terminate your rights under this License. However, parties who have

received copies, or rights, from you under this License will not have their licenses terminated so

long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else

grants you permission to modify or distribute the Program or its derivative works. These actions

are prohibited by law if you do not accept this License. Therefore, by modifying or distributing

the Program (or any work based on the Program), you indicate your acceptance of this License

to do so, and all its terms and conditions for copying, distributing or modifying the Program or

works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient

automatically receives a license from the original licensor to copy, distribute or modify the

Program subject to these terms and conditions. You may not impose any further restrictions

on the recipients’ exercise of the rights granted herein. You are not responsible for enforcing

compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other

reason (not limited to patent issues), conditions are imposed on you (whether by court order,

agreement or otherwise) that contradict the conditions of this License, they do not excuse you

from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your

obligations under this License and any other pertinent obligations, then as a consequence you

may not distribute the Program at all. For example, if a patent license would not permit royalty-

free redistribution of the Program by all those who receive copies directly or indirectly through

you, then the only way you could satisfy both it and this License would be to refrain entirely from

distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance,

the balance of the section is intended to apply and the section as a whole is intended to apply

in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right

claims or to contest validity of any such claims; this section has the sole purpose of protecting

the integrity of the free software distribution system, which is implemented by public license

practices. Many people have made generous contributions to the wide range of software

distributed through that system in reliance on consistent application of that system; it is up to the

author/donor to decide if he or she is willing to distribute software through any other system

and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the

rest of this License.

8. if the distribution and/or use of the Program is restricted in certain countries either by patents

or by copyrighted interfaces, the original copyright holder who places the Program under this

License may add an explicit geographical distribution limitation excluding those countries, so that

distribution is permitted only in or among countries not thus excluded. In such case, this License

incorporates the limitation as if written in the body of this License.
