General Notes
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 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
satisfies 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 file 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 significant 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 defined by law.
