GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright © 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 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 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 nonfree 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 nonfree 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. 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, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is

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 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
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 nonfree 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 nonfree 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.
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, which must be distributed under
the terms of Sections 1 and 2 above on
a medium customarily used for software
interchange.
If distribution of object code is made by
offering access to copy from a designated
place, then offering equivalent access to
copy the source code from the same place
satisfies the requirement to distribute the
source code, even though third parties are
not compelled to copy the source along with
the object code.

A program that contains no derivative of
any portion of the Library, but is designed to
work with the Library by being compiled or
linked with it, is called a “work that uses the
Library”. Such a work, in isolation, is not a
derivative work of the Library, and therefore
falls outside the scope of this License.
However, linking a “work that uses the
Library” with the Library creates an
executable that is a derivative of the Library
(because it contains portions of the Library),
rather than a “work that uses the library”.
The executable is therefore covered by
this License. Section 6 states terms for
distribution of such executables.
When a “work that uses the Library” uses
material from a header file that is part of the
Library, the object code for the work may be
a derivative work of the Library even though
the source code is not. Whether this is true
is especially significant if the work can be
linked without the Library, or if the work is
itself a library. The threshold for this to be
true is not precisely defined by law.
If such an object file uses only numerical
parameters, data structure layouts and
accessors, and small macros and small
inline functions (ten lines or less in length),
then the use of the object file is unrestricted,
regardless of whether it is legally a derivative
work. (Executables containing this object
code plus portions of the Library will still fall
under Section 6.)
Otherwise, if the work is a derivative of the
Library, you may distribute the object code
for the work under the terms of Section 6.
Any executables containing that work also
fall under Section 6, whether or not they are
linked directly with the Library itself.

As an exception to the Sections above, you
may also combine or link a “work that uses
the Library” with the Library to produce
a work containing portions of the Library,
and distribute that work under terms of
your choice, provided that the terms permit
modification of the work for the customer’s
own use and reverse engineering for
debugging such modifications.
You must give prominent notice with each
copy of the work that the Library is used in it
and that the Library and its use are covered
by this License. You must supply a copy of
this License. If the work during execution
displays copyright notices, you must include
the copyright notice for the Library among
them, as well as a reference directing the
user to the copy of this License. Also, you
must do one of these things:
a) Accompany the work with the complete
corresponding machine-readable source
code for the Library including whatever
changes were used in the work (which
must be distributed under Sections 1
and 2 above); and, if the work is an
executable linked with the Library, with
the complete machine-readable “work
that uses the Library”, as object code
and/or source code, so that the user
can modify the Library and then relink to
produce a modified executable containing
the modified Library. (It is understood
that the user who changes the contents
of definitions files in the Library will
not necessarily be able to recompile
the application to use the modified
definitions.)
b) Use a suitable shared library mechanism
for linking with the Library. A suitable
mechanism is one that (1) uses at run
time a copy of the library already present
on the user’s computer system, rather
than copying library functions into the
executable, and (2) will operate properly
with a modified version of the library, if the
user installs one, as long as the modified
version is interface-compatible with the
version that the work was made with.
c) Accompany the work with a written offer,
valid for at least three years, to give the
same user the materials specified in
Subsection 6a, above, for a charge no
more than the cost of performing this
distribution.
d) If distribution of the work is made by
offering access to copy from a designated
place, offer equivalent access to copy the
above specified materials from the same
place.
e) Verify that the user has already received a
copy of these materials or that you have
already sent this user a copy.
For an executable, the required form of the
“work that uses the Library” must include
any data and utility programs needed for
reproducing the executable from it.
However, as a special exception, the
materials to be distributed need not include
anything that is normally distributed (in
either source or binary form) with the major
components (compiler, kernel, and so
on) of the operating system on which the
executable runs, unless that component
itself accompanies the executable. It may
happen that this requirement contradicts
the license restrictions of other proprietary
libraries that do not normally accompany
the operating system. Such a contradiction
means you cannot use both them and the
Library together in an executable that you
distribute.

You may place library facilities that are a
work based on the Library side-by-side in
a single library together with other library
facilities not covered by this License, and
distribute such a combined library, provided
that the separate distribution of the work
based on the Library and of the other library
facilities is otherwise permitted, and provided
that you do these two things:distribute
such a combined library, provided that the
separate distribution of the work based on
the Library and of the other library facilities is
