of Section 1 above, provided that you

b) Y

c) Y
work to be licensed at no charge

of this License.
d) If a facility in the modied 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 ar
passed when the facility is
invoked, then you must make a
good faith eort 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
library to compute square roots
has a purpose that is entirely
well-dened independent of the
application.
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 modied work as a whole. If
identiable 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 par
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.

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 irr
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 Librar
into a program that is not a library.

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 oering access to copy from
a designated place, then oering
equivalent access to copy the source
code from the same place satises 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 Librar
designed to work with the Library by
being compiled or linked with it, is
called a "work that uses the Librar
Such a work, in isolation, is not a
derivative work of the Library, and
therefore falls outside the scope of this
License.
However

Library (because it contains por
of the Library), rather than a "

Section 6 states terms for distribution
of such executables.
When a "work that uses the Librar
uses material from a header le that
is part of the Librar
for the work may be a derivative work
of the Library even though the source
code is not. Whether this is true is
especially signicant if the work can
be linked without the Library, or if the
work is itself a library.
this to be true is not precisely dened
by law
If such an object le 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 le is unrestricted,
regardless of whether it is legally
a derivative work. (Executables
containing this object code plus
portions of the Librar
under Section 6.)
