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
