a) You must cause the modied les to carry prominent noces stang that you changed the les and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third pares under the terms of this License.
c) If the modied program normally reads commands interacvely when run, you must cause it, when started running for such
interacve use in the most ordinary way, to print or display an announcement including an appropriate copyright noce and a noce
that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these
condions, and telling the user how to view a copy of this License. (Excepon: if the Program itself is interacve but does not normally
print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modied work as a whole. If idenable secons of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License, and its terms, do not apply to those secons when you distribute them as
separate works. But when you distribute the same secons as part of a whole which is a work based on the Program, the distribuon of the whole must be on
the terms of this License, whose permissions for other licensees extend to the enre whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this secon to claim rights or contest your rights to work wrien enrely by you; rather, the intent is to exercise the right to control
the distribuon of derivave or collecve works based on the Program.
In addion, mere aggregaon of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage
or distribuon medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Secon 2) in object code or executable form under the terms of Secons 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
Secons 1 and 2 above on a medium customarily used for soware interchange; or,
b) Accompany it with a wrien oer, valid for at least three years, to give any third party, for a charge no more than your cost of
physically performing source distribuon, a complete machine-readable copy of the corresponding source code, to be distributed under
the terms of Secons 1 and 2 above on a medium customarily used for soware interchange; or,
c) Accompany it with the informaon you received as to the oer to distribute corresponding source code. (This alternave is allowed
only for noncommercial distribuon and only if you received the program in object code or executable form with such an oer, in accord
with Subsecon b above.)
The source code for a work means the preferred form of the work for making modicaons to it. For an executable work, complete
source code means all the source code for all modules it contains, plus any associated interface denion les, plus the scripts used to
control compilaon and installaon of the executable. However, as a special excepon, 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
operang system on which the executable runs, unless that component itself accompanies the executable.
If distribuon of executable or object code is made by oering access to copy from a designated place, then oering equivalent access to copy the source
code from the same place counts as distribuon of the source code, even though third pares 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 aempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automacally terminate your rights under this License. However, pares who have received copies, or
rights, from you under this License will not have their licenses terminated so long as such pares 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 derivave works. These acons are prohibited by law if you do not accept this License. Therefore, by modifying or distribung the Program (or any
work based on the Program), you indicate your acceptance of this License to do so, and all its terms and condions for copying, distribung or modifying the
Program or works based on it.
6. Each me you redistribute the Program (or any work based on the Program), the recipient automacally receives a license from the original licensor to
copy, distribute or modify the Program subject to these terms and condions. You may not impose any further restricons on the recipients’ exercise of the
rights granted herein. You are not responsible for enforcing compliance by third pares to this License.
7. If, as a consequence of a court judgment or allegaon of patent infringement or for any other reason (not limited to patent issues), condions are
imposed on you (whether by court order, agreement or otherwise) that contradict the condions of this License, they do not excuse you from the condions
of this License. If you cannot distribute so as to sasfy simultaneously your obligaons under this License and any other pernent obligaons, then as a
consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribuon of the Program by all
those who receive copies directly or indirectly through you, then the only way you could sasfy both it and this License would be to refrain enrely from
distribuon of the Program.
If any poron of this secon is held invalid or unenforceable under any parcular circumstance, the balance of the secon is intended to apply and the secon
as a whole is intended to apply in other circumstances.
