Appendix
1. You may copy and distribute verbatim copies of the Library's complete source code as
you receive it, in any medium, provided that you conspicuously and appropriately pub-
lish on each copy an appropriate copyright notice and disclaimer of warranty; keep
intact all the notices that refer to this License and to the absence of any warranty; and
distribute a copy of this License along with the Library. You may charge a fee for the
physical act of transferring 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 1above, 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 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 independ-
ent 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 licen-
sees 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 writ-
ten 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.
