ing a work based on the Library, and
copy and distribute such modifi cations
or work under the terms of Section 1
above, provided that you also meet all of
these conditions:
a) The modifi ed work must itself be a
software library. b) You must cause the fi les
modifi ed to carry prominent notices stating
that you changed the fi les 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 modifi ed 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-defi ned independent of the application.
Therefore, Subsection 2d requires that any
application-supplied function or table used
by this function must be optional: if the ap-
plication does not supply it, the square root
function must still compute square roots.)
These requirements apply to the modifi ed
work as a whole. If identifi able sections of
that work are not derived from the Library,
and can be reasonably considered inde-
pendent 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 distribu-
tion of derivative or collective works based
on the Library.
In addition, mere aggregation of another
work not based on the Library with the Li-
brary (or with a work based on the Library)
on a volume of a storage or distribution me-
dium 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 Gen-
eral 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 ordi-
nary 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 t hat 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 inter-
change.
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
