A “library” means a collection of software functions and/
or data prepared so as to be conveniently linked with
application programs (which use some of those functions
and data) to form executables.
The “Library”, below, refers to any such 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 modifi cations
and/or translated straightforwardly into another language.
(Hereinafter, translation is included without limitation in the
term “modifi cation”.)
“Source code” for a work means the preferred form of the work
for making modifi cations to it. For a library, complete source
code means all the source code for all modules it contains,
plus any associated interface defi nition fi les, plus the scripts
used to control compilation and installation of the library.
Activities other than copying, distribution and modifi cation 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 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 application 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 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 rights 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 storage or distribution medium does
not bring the other work under the scope of this License.
