You may charge a fee for the physical act of trans-
ferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the
Library or any portion of it, thus forming a work
based on the Library, and copy and distribute such
modifications or work under the terms of Section
1 above, provided that you also meet all of these
conditions:
a) The modified work must itself be a 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 meanin-
gful.
(For example, a function in a library to com-
pute 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 applica-
tion does not supply it, the square root func-
tion 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 reasona-
bly 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 rig-
hts 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 sto-
rage 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 irre-
versible for that copy, so the ordinary GNU Gene-
ral 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 accom-
pany 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 offe-
ring equivalent access to copy the source code
from the same place satisfies the requirement to
distribute the source code, even though third par-
ties 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 por-
tions 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.
