Appendix D Open Software Announcements
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.
