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, nonfree 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 you must make a good faith effort to ensure that, in the event an application does not supply such function 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 welldefined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: 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 independent 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 permissions 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 distribution 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 medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, 45 English

Finally, software patents pose a constant threat to

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

of use specified in this license.
Most GNU software, including
some libraries, is covered by the ordinary GNU General Public

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.

permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free

in non-free programs enables many more people to use the
whole GNU operating system, as well as its variant, the GNU/

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

The former contains code derived from the
library, whereas the latter must be combined with the library

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
you must make a good faith effort to ensure that, in the event
an application does not supply such function 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-
defined independent of the application.
Therefore, Subsection
2d requires that any application-supplied function or table used
by this function must be optional: 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 independent 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 permissions 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 distribution 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 medium does not bring the
other work under the scope of this License. 3. You may opt to
apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library.
To do this,
you must alter all the notices that refer to this License, so that
they refer to the ordinary GNU General Public License, version
2, instead of to this License.
(If a newer version than version
2 of the ordinary GNU General Public License has appeared,
then you can specify that version instead if you wish.)
Do not
make any other change in these notices.
Once this change
is made in a given copy, it is irreversible for that copy, so the
ordinary GNU General Public License applies to all subsequent
copies and derivative works made from that copy. This option
is useful when you wish to copy part of the code of the Library
into a program that is not a library. 4. You may copy and
distribute the Library (or a portion or derivative of it, under
Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you accompany it with
the complete corresponding machine-readable source code,
