OPEN SOURCE LICENSE
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 cus-
tomarily 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 cov-
ered 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 sig-
nificant 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 for the Library among them, as well as a reference directing the user to
the copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source code for the Library including what-
ever changes were used in the work (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 that uses the Library”, as object code and/
