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 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
