A "library" means a collection of software
functions and/or data prepared
so
as to be
conveniently linked with application programs
(which use some of those functions and data)
to
form executables.
The "Library", below, refers to any such
software library or work which has been
distributed under these terms. A "work based
on
the Library" means either the Library or any
derivative work under copyright law: that is to
say, a work containing the Library or a portion
of
it,
either verbatim or with modifications
andl
or translated straightforwardly into another
language. (Hereinafter, translation is included
without limitation
in
the term "modification".)
"Source code" for a work means the preferred
form of the work for making modifications to
it.
For
a library, complete source code means
all
the source code for all modules it contains,
plus any associated interface definition files,
plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and
modification are not covered by this License;
they are outside its scope. The act of running a
program using the Library
is
not restricted, and
output from such a program
is
covered only 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 what
the program that uses the Library does.
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. Ther.efore, 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
