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.
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,
