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.
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 your 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.
15. The warranty disclaimer contained in Sections 11 and 12 of the preceding GPL License is incorporated herein.
