GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999
Copyright © 1991, 1999 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 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 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
fi les 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 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. Toachieve 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.
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 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.
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
