Copyright (C) 1989, 1991 Free Software Foundation, Inc.

o this license document, but changing it is not allowed.

Preamble

The licenses or most sotware are designed to take away your

reedom to share and change it.By contrast, the GNU General PublicLicense is intended to guarantee your reedom to share and change

ree sotware--to make sure the sotware is ree or all its users.This

General Public License applies to most o the Free Sotware

Foundation‘s sotware and to any other program whose authors

commit to using it.(Some other Free Sotware Foundation sotware is

covered by the GNU Library General Public License instead.)You can

apply it to your programs, too.

When we speak o ree sotware, we are reerring to reedom, notprice.Our General Public Licenses are designed to make sure that you

have the reedom to distribute copies o ree sotware (and charge or

this service i you wish), that you receive source code or can get it i

you want it, that you can change the sotware or use pieces o it in

new ree programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that orbid

anyone to deny you these rights or to ask you to surrender the rights.

These restrictions translate to certain responsibilities or you i you

distribute copies o the sotware, or i you modiy it.

For example, i you distribute copies o such a program, whether

gratis or or a ee, 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 sotware, and

(2) oer you this license which gives you legal permission to copy,distribute and/or modiy the sotware.

Also, or each author‘s protection and ours, we want to make certain

that everyone understands that there is no warranty or this ree

sotware.I the sotware is modied by someone else and passed on,

wewant its recipients to know that what they have is not the original,

so that any problems introduced by others will not refect on the

original authors‘ reputations.

Finally, any ree program is threatened constantly by sotware



8

patents.We wish to avoid the danger that redistributors o a ree

program will individually obtain patent licenses, in eect making the

program proprietary.To prevent this, we have made it clear that anypatent must be licensed or everyone‘s ree use or not licensed at all.

The precise terms and conditions or copying, distribution and

modication ollow.

GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFI-

CATION

1. This License applies to any program or other work which contains

a notice placed by the copyright holder saying it may be distributed

under the terms o this General Public License.The „Program“, below,

reers 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 o it, either verbatim or with modications and/or translated

into another language.(Hereinater, translation is included without

limitation in the term „modication“.)Each licensee is addressed as

„you“. Activities other than copying, distribution and modicationare not covered by this License; they are outside its scope.The act o

running the Program is not restricted, and the output rom the Pro-

gram is covered only i its contents constitute a work based on the

Program (independent o having been made by running the Pro-

gram). Whether that is true depends on what the Program does.

2. You may copy and distribute verbatim copies o the Program‘s

source code as you receive it, in any medium, provided that you

conspicuously and appropriately publish on each copy an appropri-ate copyright notice and disclaimer o warranty; keep intact all the

notices that reer to this License and to the absence o any warranty;

and give any other recipients o the Program a copy o this License

along with the Program. You may charge a ee or the physical act

o transerring a copy, and you may at your option oer warranty

protection in exchange or a ee.



9

3. You may modiy your copy or copies o the Program or any portion

o it, thus orming a work based on the Program, and copy and

distribute such modications or work under the terms o Section 1above, provided that you also meet all o these conditions:

a) You must cause the modied les to carry prominent notices

stating that you changed the les and the date o any change.

b) You must cause any work that you distribute or publish, that in

whole or in part contains or is derived rom the Program or any

part thereo, to be licensed as a whole at no charge to all third

parties under the terms o this License.

c) I the modied program normally reads commands interactively

when run, you must cause it, when started running or 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 o this

License.(Exception: i the Program itsel is interactive but

does not normally print such an announcement, your work basedon the Program is not required to print an announcement.)

These requirements apply to the modied work as a whole.I

identiable sections o that work are not derived rom 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 o a whole which is a work based

on the Program, the distribution o the whole must be on the terms o this License, whose permissions or other licensees extend to the

entire whole, and thus to each and every part regardless o who wrote

it. Thus, it is not the intent o 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 o derivative or

collective works based on the Program.



10

In addition, mere aggregation o another work not based on the Pro-

gram with the Program (or with a work based on the Program) on a

volume o a storage or distribution medium does not bring the otherwork under the scope o this License.

3. You may copy and distribute the Program (or a work based on it,

under Section 2) in object code or executable orm under the terms

o Sections 1 and 2 above provided that you also do one o the

ollowing:

a) Accompany it with the complete corresponding machine-readable

source code, which must be distributed under the terms o Sections1 and 2 above on a medium customarily used or sotware inter-

change; or,

b) Accompany it with a written oer, valid or at least three

years, to give any third party, or a charge no more than your

cost o physically perorming source distribution, a complete

machine-readable copy o the corresponding source code, to be

distributed under the terms o Sections 1 and 2 above on a medi-

um customarily used or sotware interchange; or,

c) Accompany it with the inormation you received as to the oer

to distribute corresponding source code.(This alternative is

allowed only or noncommercial distribution and only i you

received the program in object code or executable orm with such

an oer, in accord with Subsection b above.)

The source code or a work means the preerred orm o the work or

making modications to it.For an executable work, complete source

code means all the source code or all modules it contains, plus anyassociated interace denition les, plus the scripts used to

control compilation and installation o the executable.However, as a

special exception, the source code distributed need not include

anything that is normally distributed (in either source or binary

orm) with the major components (compiler, kernel, and so on) o the

operating system on which the executable runs, unless that compo-

nent itsel accompanies the executable.



11

I distribution o executable or object code is made by oering

access to copy rom a designated place, then oering equivalent

access to copy the source code rom the same place counts asdistribution o the source code, even though third parties are not

compelled to copy the source along with the object code.

4. You may not copy, modiy, sublicense, or distribute the Program

except as expressly provided under this License.Any attempt

otherwise to copy, modiy, sublicense or distribute the Program is

void, and will automatically terminate your rights under this License.

However, parties who have received copies, or rights, rom you

under this License will not have their licenses terminated so long assuch parties remain in ull compliance.

5. You are not required to accept this License, since you have not

signed it.However, nothing else grants you permission to modiy or

distribute the Program or its derivative works.These actions are

prohibited by law i you do not accept this License.Thereore, by

modiying or distributing the Program (or any work based on the

Program), you indicate your acceptance o this License to do so, and

all its terms and conditions or copying, distributing or modiying

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 rom the

original licensor to copy, distribute or modiy the Program subject

to these terms and conditions.You may not impose any urther

restrictions on the recipients‘ exercise o the rights granted herein.

You are not responsible or enorcing compliance by third parties to

this License.

7. If, as a consequence of a court judgment or allegation of patent

inringement or or any other reason (not limited to patent issues),

conditions are imposed on you (whether by court order, agreement

or otherwise) that contradict the conditions o this License, they do

not excuse you rom the conditions o License.I you cannot

distribute so as to satisy 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, i a patent

license would not permit redistribution o the Program by



12

all those who receive copies directly or indirectly through you, then

the only way you could satisy both it and this License would be to

rerain entirely rom distribution o the Program.

I any portion o this section is held invalid or unenorceable under

any particular circumstance, the balance o the section is intended to

apply and the section as a whole is intended to apply in other

circumstances.

It is not the purpose o this section to induce you to inringe any

patents or other property right claims or to contest validity o any

such claims; this section has the sole purpose o protecting theintegrity o the ree sotware distribution system, which is

implemented by public license practices.Many people have made

generous contributions to the wide range o sotware distributed

through that system in reliance on consistent application o that

system; it is up to the author/donor to decide i he or she is willing

to distribute sotware through any other system and a licensee can-

not impose that choice.

This section is intended to make thoroughly clear what is believed to

be a consequence o the rest o this License.

8. If the distribution and/or use of the Program is restricted in

certain countries either by patents or by copyrighted interaces, 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 i written in the body o this License.

9. The Free Software Foundation may publish revised and/or new

versions o the General Public License rom time to time.Such new

versions will be similar in spirit to the present version, but may dier

in detail to address new problems or concerns.

Each version is given a distinguishing version number.I the Program

species a version number o this License which applies to it and „any

later version“, you have the option o ollowing the terms and con-

ditions either o that version or o any later version published by the



13

Free Sotware Foundation.I the Program does not speciy a version

number o this License, you may choose any version ever published

by the Free Sotware Foundation.

10. If you wish to incorporate parts of the Program into other free

programs whose distribution conditions are dierent, write to the

author to ask or permission.For sotware which is copyrighted

by the Free Sotware Foundation, write to the Free Sotware

Foundation; we sometimes make exceptions or this.Our decision

will be guided by the two goals o preserving the ree status o all

derivatives o our ree sotware and o promoting the sharing and

reuse o sotware generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS

NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

APPLICABLE LAW.EXCEPT WHEN OTHERWISE STATED IN WRITING

THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE

PROGRAM „AS IS“ WITHOUT WARRANTY OF ANY KIND, EITHER

EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FORA PARTICULAR PURPOSE.THE ENTIRE RISK AS TO THE QUALITY

AND PERFORMANCE OF THE PROGRAM IS WITH YOU.SHOULD

THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL

NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED

TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER

PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM

AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLU-DING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL

DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR

DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPE-

RATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR

OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH

DAMAGES.
