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 modified work as a
whole. If identifiable 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 modifications to it. For an executable
work, complete source code means all the source code for
all modules it contains, plus any associated interface
definition files, 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
