GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February
1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.

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 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.>
