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.
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 Foundation 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
detail to address new problems or concerns. Each version is given a distinguishing version number. If the
Program specifies a version number of this License which 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
