Licenses
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
modifi ed executable containing the modifi ed Library.
(It is understood that the user who changes the
contents of defi nitions fi les in the Library will not
necessarily be able to recompile the application to
use the modifi ed defi nitions.)
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 modifi ed version of
the library, if the user installs one, as long as the
modifi ed 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 specifi ed 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 specifi ed 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:
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 fi nd 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 specifi es 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 fi le to most effectively convey the exclusion
of warranty; and each fi le 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.>
