tions and data) to form executables
The "Library", below, refers to any such software library or work which has been
istributed under these terms.
"work based on the Library" means either the

the Library or a portion of it, either verbatim or with modiÀ cations and/or trans-
ated straightforwardly into another language. (Hereinafter, translation is included
without limitation in the term "modiÀ cation".)
"Source code" for a work means the preferred form of the work for making modi-
À cations to it. For a library, complete source code means all the source code fo
all modules it contains, plus any associated interface deÀ nition À les, plus the scripts
used to control compilation and installation of the library
Activities other than copying, distribution and modiÀ cation are not covered by this
License; they are outside its scope. The act of running a program using the Library
s not restricted, and out
ut from such a
ro
ram is covered onl
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

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 modiÀ cations

The modiÀ ed work must itself be a software librar
b) You must cause the À les modiÀ ed to carry prominent notices stating that you
changed the À les and the date of any change
c
You must cause the whole of the work to be licensed at no char
e to all third
parties under the terms of this License
) If a facility in the modiÀ ed Library refers to a function or a table of data to
be su
lied b
an a
lication
ro
ram that uses the facilit
, 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 o
able, the facility still operates, and performs whatever part of its purpose remains
meaningful
For exam
le, a function in a librar
to com
ute s
uare roots has a
ur
ose that
s entirely well-deÀ ned independent of the application. Therefore, Subsection 2d
requires that any application-supplied function or table used by this function must
be o
tional: if the a
lication does not su
l
it, the s
uare root function must
still compute square roots.
hese requirements apply to the modiÀ ed work as a whole. If identiÀ able sections
of that work are not derived from the Librar

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 distribu-

"work that uses the Library". Such a work, in isolation, is not a derivative work o
the Librar
, and therefore falls outside the sco
e of this License
However, linkin
a
work that uses the Librar
with the Librar
creates an execut-
able that is a derivative of the Library (because it contains portions of the Library)
rather than a "work that uses the librar
". The executable is therefore covered b
this License. Section 6 states terms for distribution of such executables
When a "work that uses the Library" uses material from a header À le that is part
of the Librar
, the ob
ect code for the work ma
be a derivative work of the
Library even though the source code is not. Whether this is true is especially signiÀ -
ant if the work can be linked without the Library, or if the work is itself a library.
he threshold for this to be true is not precisely deÀ ned by law
If such an object À le uses only numerical parameters, data structure layouts and
accessors, and small macros and small inline functions (ten lines or less in length)
hen the use of the object À 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
ode 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

a) Accompany the work with the complete corresponding machine-readable

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
hat uses the Library", as object code and/or source code, so that the user can
modify the Library and then relink to produce a modiÀ ed executable containing
he modiÀ ed Library. (It is understood that the user who changes the contents
f deÀ nitions À les in the Librar
will not necessaril
be able to recom
ile the
application to use the modiÀ ed deÀ nitions.)
) Use a suitable shared library mechanism for linking with the Library. A suitable
mechanism is one that

uses at run time a co

alread
resent
n the user's computer system, rather than copying library functions into the
executable, and (2) will operate properly with a modiÀ ed version of the library, if

) Accompany the work with a written offer, valid for at least three years, to give

more than the cost of performing this distribution
