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
bit 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. 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
