GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

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 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.

GNU GENERAL PUBLIC LICENSE

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 copyright

holder saying it may be distributed under the terms of this General Public License. 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

Irrtum und Änderungen vorbehalten

93

ALL-SG8452M – User Manual

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.

Irrtum und Änderungen vorbehalten

94

ALL-SG8452M – User Manual

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 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

Irrtum und Änderungen vorbehalten

95

ALL-SG8452M – User Manual

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 "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

Irrtum und Änderungen vorbehalten

96

ALL-SG8452M – User Manual

PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR

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, 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.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the

best way to achieve this is to make it free software which everyone can redistribute and change under

these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each

source file to most effectively convey the exclusion of warranty; and each file should have at least the

"copyright" line and a pointer to where the full notice is found.

<one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name

of author>

This program is free software; you can redistribute it and/or modify it under the terms of the GNU

General Public License as published by the Free Software Foundation; either version 2 of the License,

or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without

even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this program; if not,

write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,

USA

Also add information on how to contact you by electronic and paper mail. 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:

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.

LICENSE.LGPLv2.1

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999

02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license

document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also

counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.]

Preamble

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

contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and

change free software--to make sure the software is free for all its users.

This license, the Lesser General Public License, applies to some specially designated software

packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.

You can use it too, but we suggest you first think carefully about whether this license or the ordinary

General Public License is the better strategy to use in any particular case, based on the explanations

below.

When we speak of free software, we are referring to freedom of use, 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 and use pieces of it in new free programs; and that you are informed

that you can do these things.

To protect your rights, we need to make restrictions that forbid distributors to deny you these rights

or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you

if you distribute copies of the library or if you modify it.

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

recipients all the rights that we gave you. You must make sure that they, too, receive or can get the

source code. If you link other code with the library, you must provide complete object files to the

Irrtum und Änderungen vorbehalten

98

ALL-SG8452M – User Manual

recipients, so that they can relink them with the library after making changes to the library and

recompiling it. And you must show them these terms so they know their rights.

We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this

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

To protect each distributor, we want to make it very clear that there is no warranty for the free

library. Also, if the library is modified by someone else and passed on, the recipients should know

that what they have is not the original version, so that the original author's reputation will not be

affected by problems that might be introduced by others.

Finally, software patents pose a constant threat to the existence of any free program. We wish to

make sure that a company cannot effectively restrict the users of a free program by obtaining a

restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a

version of the library must be consistent with the full freedom of use specified in this license.

Most GNU software, including some libraries, is covered by the ordinary GNU General Public License.

This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite

different from the ordinary General Public License. We use this license for certain libraries in order

to permit linking those libraries into non-free programs.

When a program is linked with a library, whether statically or using a shared library, the combination

of the two is legally speaking a combined work, a derivative of the original library. The ordinary

General Public License therefore permits such linking only if the entire combination fits its criteria of

freedom. The Lesser General Public License permits more lax criteria for linking other code with the

library.

We call this license the "Lesser" General Public License because it does Less to protect the user's

freedom than the ordinary General Public License. It also provides other free software developers

Less of an advantage over competing non-free programs. These disadvantages are the reason we

use the ordinary General Public License for many libraries. However, the Lesser license provides

advantages in certain special circumstances.

For example, on rare occasions, there may be a special need to encourage the widest possible use of a

certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be

allowed to use the library. A more frequent case is that a free library does the same job as widely

used non-free libraries. In this case, there is little to gain by limiting the free library to free software

only, so we use the Lesser General Public License.

In other cases, permission to use a particular library in non-free programs enables a greater number of

people to use a large body of free software. For example, permission to use the GNU C Library in

non-free programs enables many more people to use the whole GNU operating system, as well as its

variant, the GNU/Linux operating system.

Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that

the user of a program that is linked with the Library has the freedom and the wherewithal to run that

program using a modified version of the Library.

The precise terms and conditions for copying, distribution and modification follow. Pay close

attention to the difference between a "work based on the library" and a "work that uses the library".

The former contains code derived from the library, whereas the latter must be combined with the

library in order to run.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License Agreement applies to any software library or other program which contains a notice

placed by the copyright holder or other authorized party saying it may be distributed under the terms

of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".

A "library" means a collection of software functions and/or data prepared so as to be conveniently

linked with application programs (which use some of those functions and data) to form executables.

The "Library", below, refers to any such software library or work which has been distributed under

these terms. A "work based on the Library" means either the Library or any derivative work under

copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with

modifications and/or translated straightforwardly into another language. (Hereinafter, translation is

included without limitation in the term "modification".)

"Source code" for a work means the preferred form of the work for making modifications to it. For

a library, 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

library.

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

outside its scope. The act of running a program using the Library is not restricted, and output from

such a program is covered only if its contents constitute a work based on the Library (independent of

the use of the Library in a tool for writing it). Whether that is true depends on what the Library does

and what the program that uses the Library does.

1. You may copy and distribute verbatim copies of the Library's complete 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 distribute a copy of this License along with the Library.

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 Library or any portion of it, thus forming a work based on

the Library, 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) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files

and the date of any change.

c) You must cause the whole of the work to be licensed at no charge to all third parties under the

terms of this License.

d) If a facility in the modified Library refers to a function or a table of data to be supplied by an

application program that uses the facility, other than as an argument passed when the facility is

invoked, then you must make a good faith effort to ensure that, in the event an application does

not supply such function or table, the facility still operates, and performs whatever part of its

purpose remains meaningful.

(For example, a function in a library to compute square roots has a purpose that is entirely

well-defined independent of the application. Therefore, Subsection 2d requires that any

application-supplied function or table used by this function must be optional: if the application

does not supply it, the square root function must still compute square roots.)

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