are prohibited by law if you do not accept this License. T herefore,
by modifying or distributing the Program (or any work based on the
Program), you indicate your accept ance 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. Y ou may not impose any further restrictions
on the recipients'exercise of the rights granted herein. Y ou 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 circumst ance, 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 F oundation may publish revised and/
or new versions of the General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in det ail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License whic h applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software F oundation. If the Program does not specify a version number
of this License, you may choose any version ever published by the Free
Software Foundation.
1 0. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted by the
Free Software Foundation, write to the Free Software Foundation; we
sometimes make exceptions for this. Our decision will be guided by
the two goals of preserving the free status of all derivatives of our free
software and of promoting the sharing and reuse of software generally .

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 s ame 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 eac h 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.

. Y ou 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. F or an execut able work, complete source
code means all the source code for all modules it cont ains, plus any
associated interface definition files, plus the scripts used to control
compilation and installation of the execut able. 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. Y ou 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 suc h parties remain in
full compliance.
5. Y ou 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. T hese actions
