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.

2 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.

1 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.

2 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.

3 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.

4 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.

1 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.

2 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

1 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.
2 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.
