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.

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.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable
form under the terms of Sections 1 and 2 above provided that
you accompany it with the complete corresponding machine-
readable source code, which must be distributed under the
terms of Sections 1 and 2 above on a medium customarily used
for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy
the source code from the same place satisfies the requirement
to distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5.
A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being
compiled or linked with it, is called a "work that uses the
Library". Such a work, in isolation, is not a derivative work of the
Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because
it contains portions of the Library), rather than a "work that uses
the library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a
header file that is part of the Library, the object code for the
work may be a derivative work of the Library even though the
source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small
inline functions (ten lines or less in length), then the use of the
object file is unrestricted, regardless of whether it is legally a
derivative work. (Executables containing this object code plus
portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of
Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6.
As an exception to the Sections above, you may also combine
or link a "work that uses the Library" with the Library to
produce a work containing portions of the Library, and
distribute that work under terms of your choice, provided
that the terms permit modification of the work for the
customer's own use and reverse engineering for debugging such
modifications.
You must give prominent notice with each copy of the work
that the Library is used in it and that the Library and its use are
covered by this License. You must supply a copy of this License. If
the work during execution displays copyright notices, you must
include the copyright notice for the Library among them, as well
as a reference directing the user to the copy of this License. Also,
you must do one of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including
whatever changes were used in the work (which must be
distributed under Sections 1 and 2 above); and, if the work
is an executable linked with the Library, with the complete
machine-readable "work that uses the Library", as object
code and/or source code, so that the user can modify the
Library and then relink to produce a modified executable
containing the modified Library. (It is understood that
the user who changes the contents of definitions files in
the Library will not necessarily be able to recompile the
application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with
the Library. A suitable mechanism is one that (1) uses at
run time a copy of the library already present on the user's
computer system, rather than copying library functions into
the executable, and (2) will operate properly with a modified
