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,
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,
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.
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.
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.
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.
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.
