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 announcement, your work based on the Program is not required to print 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 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) 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 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.
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
