GNU Lesser GPL 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 liked 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 propriety 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 
CONSQUENTIAL 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.
