Third Party Copyrights and License Terms
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 specifi ed 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 fi ts 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 modifi ed version
of the Library.
The precise terms and conditions for copying, distribution and modifi cation 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 modifi cations and/or translated straightforwardly
into another language. (Hereinafter, translation is included without limitation in the term „modifi cation".)
„Source code" for a work means the preferred form of the work for making modifi cations to it. For a library, complete
source code means all the source code for all modules it contains, plus any associated interface defi nition fi les,
plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modifi cation 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 medi-
um, 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.
