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, Sub-
section 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 dentifiable sec-
tions of that work are not derived from the Library, and can be reasonably con-
sidered 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 Li-
cense.
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 deriv-
ative 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, un-
der 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 desig-
nated 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 ex-
ecutable that is a derivative of the Library (because it contains portions of the Li-
brary), rather than a "work that uses the library". The executable is therefore
covered by this License. Section 6 states terms for distribution of such executa-
bles.
When a "work that uses the Library" uses material from a header fi le 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 sig-
nificant if the work can be linked without the Library, or if the work is itself a li-
brary. 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 ob-
ject 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 re-
verse 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 no-
tices, 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 modi-
fied 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 defini-
tions.)
b) Use a suitable shared library mechanism for linking with the Library. A suit-
able 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 func-
tions into the executable, and (2) will operate properly with a modified ver-
sion 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 des-
ignated 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 sys-
tem on which the executable runs, unless that component itself accompanies the
executable.
It may happen that this requirement contradicts the license restrictions of oth-
er 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 dis-
tribution of the work based on the Library and of the other library facilities is oth-
erwise 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 dis-
tributed 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 accompany-
ing 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 automat-
ically terminate your rights under this License. However, parties who have re-
ceived 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 infringe-
ment or for any other reason (not limited to patent issues), conditions are im-
posed 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 cop-
ies directly or indirectly through you, then the only way you could satisfy both it
