2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files 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 parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such
interactive use in the most ordinar
y way, to print or display an announcement including an appropriate copyright notice and a notice
that there is no
warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these
condi
tions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not
normall
y print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements appl
y to the modified work as a whole. If identifiable sections of that work are not derived from the Program,
and can be reasonabl
y considered independent and separate works in themselves, then this License, and its terms, do not apply to
those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other
licensees extend to the entire
whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation 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 distribution 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 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) Accompan
y 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
ph
ysically 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) Accompan
y it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed
onl
y 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
in
clude anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on)
of the operating s
ystem on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code i
s 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
modif
ying 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 an
y 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 an
y 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.
