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
40
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
