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
