VarioLink 9522 (Version 2) 13-55Appendix 13Use of any of this software is governed by the terms of the license below:GNU LIBRARY GENERAL PUBLIC LICENSETERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION0. This License Agreement applies to any software library which contains a notice placed by the copyrightholder or other authorized party saying it may be distributed under the terms of this Library General PublicLicense (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 withapplication 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 "workbased on the Library" means either the Library or any derivative work under copyright law: that is to say, awork containing the Library or a portion of it, either verbatim or with modifications and/or translatedstraightforwardly 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 interfacedefinition files, plus the scripts used to control compilation and installation of the library. Activities other thancopying, distribution and modification are not covered by this License; they are outside its scope. The act ofrunning a program using the Library is not restricted, and output from such a program is covered only if itscontents 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, inany medium, provided that you conspicuously and appropriately publish on each copy an appropriatecopyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to theabsence 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 warrantyprotection 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 theLibrary, and copy and distribute such modifications or work under the terms of Section 1above, provided thatyou 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 thedate 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 ofthis License.d) If a facility in the modified Library refers to a function or a table of data to be supplied by an applicationprogram that uses the facility, other than as an argument passed when the facility is invoked, then you mustmake 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-definedindependent of the application. Therefore, Subsection 2d requires that any application-supplied function ortable used by this function must be optional: if the application does not supply it, the square root functionmust still compute square roots.)These requirements apply to the modified work as a whole. If identifiable sections of that work are not derivedfrom the Library, and can be reasonably considered independent and separate works in themselves, then thisLicense, and its terms, do not apply to those sections when you distribute them as separate works. But whenyou distribute the same sections as part of a whole which is a work based on the Library, the distribution ofthe whole must be on the terms of this License, whose permissions for other licensees extend to the entirewhole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section toclaim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right tocontrol the distribution of derivative or collective works based on the Library. In addition, mere aggregationof another work not based on the Library with the Library (or with a work based on the Library) on a volumeof a storage or distribution medium does not bring the other work under the scope of this License.3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to agiven copy of the Library. To do this, you must alter all the notices that refer to this License, so that they referto the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version thanversion 2 of the ordinary GNU General Public License has appeared, then you can specify that version insteadif you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it isirreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies andderivative works made from that copy.
