warranty; keep intact all the notices that refer to this License and
to the absence of any warranty; and give any other recipients of
the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in
exchange for a fee.
2. You may modify your copy or copies of the Program or any
portion of it, thus forming a work based on the Program, and
copy and distribute such modifications or work under the terms
of Section 1 above, provided that you also meet all of these
conditions: a) You must cause the modified files to carry
prominent notices stating that you changed the files and the date
of any change. b) You must cause any work that you distribute
or publish, that in whole or in part contains or is derived from
the Program or any part thereof, to be licensed as a whole at no
charge to all third parties under the terms of this License. c) If
the modified 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 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 non-commercial 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
