GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 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 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 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 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.
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:
a) Accompany the combined
library with a copy of the same work
based on the Library, uncombined
with any other library
facilities. This must be distributed under the
terms of the
Sections above.
b) Give prominent notice with the
combined library of the fact
that part of it is a work based on the
Library, and explaining
where to find the accompanying uncombined form
of the same work.
8. You may not copy, modify, sublicense, link with, or
distribute
the Library except as expressly provided under this License.
Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute
the Library is void, and will automatically terminate your
rights under
this License. However, parties who have received copies,
or rights, from
you under this License will not have their licenses
terminated so long as
such parties remain in full compliance.
9. You are not required to
accept this License, since you have not
signed it. However, nothing else
grants you permission to modify or
distribute the Library or its derivative
works. These actions are
prohibited by law if you do not accept this
License. Therefore, by
modifying or distributing the Library (or any work
based on the
Library), you indicate your acceptance of this License to do
so, and
all its terms and conditions for copying, distributing or
modifying
the Library or works based on it.
10. Each time you
redistribute the Library (or any work based on the
Library), the recipient
automatically receives a license from the
original licensor to copy,
distribute, link with or modify the Library
subject to these terms and
conditions. You may not impose any further
restrictions on the recipients'
exercise of the rights granted herein.
You are not responsible for
enforcing compliance by third parties with
this License.
11. If, as a
consequence of a court judgment or allegation of patent
infringement or for
any other reason (not limited to patent issues),
conditions are imposed on
you (whether by court order, agreement or
otherwise) that contradict the
conditions of this License, they do not
excuse you from the conditions of
this License. If you cannot
distribute so as to satisfy simultaneously
your obligations under this
License and any other pertinent obligations,
then as a consequence you
may not distribute the Library at all. For
example, if a patent
license would not permit royalty-free redistribution
of the Library by
all those who receive copies directly or indirectly
through you, then
the only way you could satisfy both it and this License
would be to
refrain entirely from distribution of the Library.
If any
portion of this section is held invalid or unenforceable under
any
particular circumstance, the balance of the section is intended to
apply,
and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to
infringe any
patents or other property right claims or to contest validity
of any
such claims; this section has the sole purpose of protecting
the
integrity of the free software distribution system which is
implemented
by public license practices. Many people have made
generous contributions
to the wide range of software distributed
through that system in reliance
on consistent application of that
system; it is up to the author/donor to
decide if he or she is willing
to distribute software through any other
system and a licensee cannot
impose that choice.
This section is intended
to make thoroughly clear what is believed to
be a consequence of the rest
of this License.
12. If the distribution and/or use of the Library is
restricted in
certain countries either by patents or by copyrighted
interfaces, the
original copyright holder who places the Library under this
License may add
an explicit geographical distribution limitation excluding
those countries,
so that distribution is permitted only in or among
countries not thus
excluded. In such case, this License incorporates the
limitation as if
written in the body of this License.
13. The Free
Software Foundation may publish revised and/or new
versions of the Lesser
General Public License from time to time.
Such new versions will be similar
in spirit to the present version,
but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version
number. If the Library
specifies a version number of this License which
applies to it and
"any later version", you have the option of
following the terms and
conditions either of that version or of any later
version published by
the Free Software Foundation. If the Library does not
specify a
license version number, you may choose any version ever published
by
the Free Software Foundation.
14. If you wish to incorporate parts
of the Library into other free
programs whose distribution conditions are
incompatible with these,
write to the author to ask for permission. For
software which is
copyrighted by the Free Software Foundation, write to the
Free
Software Foundation; we sometimes make exceptions for this.
Our
decision will be guided by the two goals of preserving the free
status
of all derivatives of our free software and of promoting the
sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE
THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE
LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE
LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE
LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW
OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO
MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO
YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL
OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR
A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply
These Terms to Your New Libraries
If you develop a new library, and you
want it to be of the greatest
possible use to the public, we recommend
making it free software that
everyone can redistribute and change. You can
do so by permitting
redistribution under these terms (or, alternatively,
under the terms of the
ordinary General Public License).
To apply these
terms, attach the following notices to the library. It is
safest to attach
them to the start of each source file to most effectively
convey the
exclusion of warranty; and each file should have at least
the
"copyright" line and a pointer to where the full notice is
found.
<one line to give the library's name and a brief idea of
what it does.>
