Open Source Licensing Remarks

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 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 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
