GNU Lesser General Public License 2.1

GNU LESSER GENERAL PUBLIC LICENSE 

Version 2.1, February 1999 

Copyright (C) 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 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. 

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.
