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 modifi cations to it. For an executable work,
complete source code means all the source code for all modules it contains, plus any associated interface defi nition
fi les, 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 specifi es 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 the Free Software Foundation. If the Program does not specify a version number of this
License, you may choose any version ever published by the Free Software Foundation.
10. 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
