Additional Information
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
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
