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 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.
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 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 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 le 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 signicant 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 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 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 modication
of the work for the customer's own use and reverse
engineering for debugging such modications.
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
modied executable containing the modied Library. (It
is understood that the user who changes the contents of
denitions les in the Library will not necessarily be able to
recompile the application to use the modied denitions.)
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 modied version of the library, if the user
installs one, as long as the modied version is interface-
compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for
at least three years, to give the same user the materials
specied in Subsection 6a, above, for a charge no
more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to
copy from a designated place, offer equivalent access to copy
the above specied materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy. For
an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed
for reproducing the executable from it. However, as a special
exception, the materials to be distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so
on) of the operating system on which the executable runs,
unless that component itself accompanies the executable.
It may happen that this requirement contradicts the
license restrictions of other proprietary libraries that do
