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
condition:
You must cause the modified files to carry prominent notices stating that you changed the files and the date of any
change.
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 there of, to be licensed as a whole at no charge to all third parties under the terms of the this
License.
If the modified Program normally reads commands interactively when run, you must cause it, when started running
for such interactive use in the most ordinary 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 conditions, and telling the user how to view a copy of this License. (Exception: if
the program itself is interactive but does not normally print such an nnouncement, your work based on the program is
not required to print such an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections 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 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 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 and 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.
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:
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,
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,
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 distributes
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.
You many 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.
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 and distributing the Program (or any works 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.
Each time you redistribute the Program (or any works 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 recipient’s exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
