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 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, it is irreversible for that copy, so the ordinary
GNU General Public License applies to all subsequent copies and derivative works
made from that copy.
This option is useful when you wish to copy part of the code of the Library into a
program that is not a library.
