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 nonfree 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 di erence 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
1. 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.
2. 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
o er warranty protection in exchange for a fee.
3. 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 modifi cations or work under the terms of
Section 1 above, provided that you also meet all of these conditions:
1) The modifi ed work must itself be a software library.
2) You must cause the fi les modifi ed to carry prominent notices stating that you changed
