tain 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 ori-
ginal library. The ordinary General Public License there-
fore 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 com-
peting 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, permis-
sion to use the GNU C Library in non-free programs enab-
les 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 protec-
tive 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 modi-
fied version of the Library.
The precise terms and conditions for copying, distribu-
tion 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 com-
bined 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 ver-
batim or with modifications and/or translated straightfor-
wardly 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, com-
plete source code means all the source code for all modu-
les 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 modifica-
tion 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 appropri-
ately 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 protec-
tion 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 promi-
nent 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 func-
tion or a table of data to be supplied by an applica-
tion 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 func-
tion 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-defi-
ned independent of the application. Therefore, Sub-
section 2d requires that any application-supplied
function or table used by this function must be opti-
onal: if the application does not supply it, the square
root function must still compute square roots.)

These requirements apply to the modified work as a
whole. If identifiable sections of that work are not derived
from the Library, and can be reasonably considered inde-
pendent and separate works in themselves, then this
License, and its terms, do not apply to those sections
when you distribute them as separate works. But when
you distribute the same sections as part of a whole which
is a work based on the Library, the distribution of the
whole must be on the terms of this License, whose per-
missions for other licensees extend to the entire whole,
and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather,
the intent is to exercise the right to control the distribu-
tion of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based
on the Library with the Library (or with a work based on
the Library) on a volume of a storage or distribution
