Gigaset C470 IP/C475 IP – Free software
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.
GNU LESSER GENERAL PUBLIC LICENSE
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 lin-
ked 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 copy-
right law: that is to say, a work containing the Library or a portion of it, either verbatim or with modi-
fications and/or translated straightforwardly into another language. (Hereinafter, translation is inclu-
ded 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 associa-
ted 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 appro-
priate 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 war-
ranty 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 appli-
cation 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
