Chapter 12: Appendix
a whole at no charge to all third parties under the terms
of this License.
c) If the modied program normally reads commands
interactively when run, you must cause it, when started
running for such interactive use in the most ordinary
way, to print or display an announcement including an
appropriate copyright notice and a notice that there
is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program
under these conditions, and telling the user how to
view a copy of this License. (Exception: if the Program
itself is interactive but does not normally print such an
announcement, your work based on the Program is not
required to print an announcement.)
These requirements apply to the modied work as
a whole. If identiable sections of that work are not
derived from the Program, 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 Program, 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 Program.
In addition, mere aggregation of another work not based on
the Program with the Program (or with a work based on the
Program) on a volume of a storage or distribution medium
does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based
on it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you
also do one of the following:
a) 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; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to
be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the
offer to distribute corresponding source code. (This alternative
is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with
such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of
the work for making modications to it. For an executable
work, complete source code means all the source code
for all modules it contains, plus any associated interface
denition les, plus the scripts used to control compilation and
installation of the executable.
However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either
source or binary form) with the major components (compiler,
kernel, and so on) of the operating system on which the
executable runs, unless that component itself accompanies
the executable.
If distribution of executable or 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 counts as distribution of the source code, even though
third parties are not compelled to copy the source along with
the object code.
4. You may not copy, modify, sublicense, or distribute the
Program except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense or distribute the
Program is void, and will automatically terminate your rights
under this License.
However, parties who have received copies, or rights, from
you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have
not signed it. However, nothing else grants you permission to
modify or distribute the Program or its derivative works. These
actions are prohibited by law if you do not accept this License.
Therefore, by modifying or distributing the Program (or any
work based on the Program), you indicate your acceptance
of this License to do so, and all its terms and conditions for
copying, distributing or modifying the Program or works based
on it.
6. Each time you redistribute the Program (or any work based
on the Program), the recipient automatically receives a license
from the original licensor to copy, distribute or modify the
Program subject to these terms and conditions. You may not
impose any further restrictions on the recipients’ exercise of
the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation
of patent infringement or for any other reason (not limited
to patent issues), conditions are imposed on you (whether
by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the
conditions of this License. If you cannot distribute so as to
satisfy simultaneously your obligations under this License and
any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the
Program by all those who receive copies directly or indirectly
through you, then the only way you could satisfy both it and
this License would be to refrain entirely from distribution of
the Program.
If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section
is intended to apply and the section as a whole is intended to
apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system, which is
implemented by public license practices. Many people have
made generous contributions to the wide range of software
distributed through that system in reliance on consistent
application of that system; it is up to the author/donor to decide
if he or she is willing to distribute software through any other
system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is
believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted
in certain countries either by patents or by copyrighted
interfaces, the original copyright holder who places the
Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not
thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/
or new versions of the General Public License from time to
