_ appendix
a notice placed by the copyright holder or other
authorized party saying it may be distributed
under the terms of this Lesser General Public
License (also called “this License”). Each licensee
is addressed as “you”.
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 and/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.
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.
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
