GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

[This is the ﬁ rst 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
ﬁ rst 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
grants 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 ﬁ les to the
recipients, so that they can re-link 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 modiﬁ ed 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
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
