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 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.
