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.

GNU 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 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
