software library or work which has been distributed under these terms. A "work
based on the Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a portion of it, either
verbatim or with modifications and/or translated straightforwardly into another
language. (Hereinafter, translation is included without limitation in the term
"modification".)
"Source code" for a work means the preferred form of the work for making
modifications to it. For a library, complete source code means all the source code
for all modules it contains, plus any associated interface definition files, plus the
scripts used to control compilation and installation of the library. Activities other
than copying, distribution and modification are not covered by this License; they
are outside its scope. The act of running a program using the Library is not
restricted, and output from such a program is covered only if its contents
constitute a work based on the Library (independent of the use of the Library in a
tool for writing it). Whether that is true depends on what the Library does and
what the program that uses the Library does.
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 publish 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 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
