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. If such an object file 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 file 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 modification of the work for the
customer's own use and reverse engineering for debugging such
modifications. 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
