ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL

DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this

license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.

It also counts as the successor of the GNU Library Public License, version

2, hence the version number 2.1.]

Preamble

The licenses for most software are designed to take away your freedom to

share and change it. By contrast, the GNU General Public Licenses are

intended to guarantee your freedom to share and change free software to

make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially

designated software packages--typically libraries--of the Free Software

Foundation and other authors who decide to use it. You can use it too, but

we suggest you first think carefully about whether this license or the

ordinary General Public License is the better strategy to use in any

particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, not

price. Our General Public Licenses are designed to make sure that you

have the freedom to distribute copies of free software (and charge for this

service if you wish); that you receive source code or can get it if you want

it; that you can change the software and use pieces of it in new free
programs; and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors

to deny you these rights or to ask you to surrender these rights. These

restrictions translate to certain responsibilities for you if you distribute

copies of the library or if you modify it.

For example, if you distribute copies of the library, whether gratis or for a

fee, you must give the recipients all the rights that we gave you. You must

make sure that they, too, receive or can get the source code. If you link

other code with the library, you must provide complete object files to the

recipients, so that they can relink them with the library after making

changes to the library and recompiling it. And you must show them these

terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the

library, and (2) we offer you this license, which gives you legal permission

to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no

warranty for the free library. Also, if the library is modified by someone else

and passed on, the recipients should know that what they have is not the

original version, so that the original author’s reputation will not be affected

by problems that might be introduced by others.
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 specified 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 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.

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.
