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 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 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 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 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 offer

warranty 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

application 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

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-

defined independent of the application. Therefore,

Subsection 2d requires that any application-supplied

function or table used by this function must be
