GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

59 Temple Place - Suite 330, Boston, MA 02111-1307, 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

Page 267 / 292

Appendix F Open Software Announcements

NBG-419N User’s Guide

267

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

Library 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

"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

Page 269 / 292

Appendix F Open Software Announcements

NBG-419N User’s Guide

269

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.

9. The Free Software Foundation may publish revised and/or new versions of the General Public

License from time to time. Such new versions will be similar in spirit to the present version, but

may differ in detail to address new problems or concerns. Each version is given a distinguishing

version number. If the Program specifies a version number of this License which applies to it and

Page 270 / 292

Appendix F Open Software Announcements

NBG-419N User’s Guide

270

"any later version", you have the option of following the terms and conditions either of that version

or of any later version published by the Free Software Foundation. If the Program does not specify

a version number of this License, you may choose any version ever published by the Free Software

Foundation.

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

conditions are different, write to the author to ask for permission. For software which is copyrighted

by the Free Software Foundation, write to the Free Software Foundation; we sometimes make

exceptions for this. Our decision will be guided by the two goals of preserving the free status of all

derivatives of our free software and of promoting the sharing and reuse of software 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 FOR A 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

PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING 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 OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
