and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a
work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as
"you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The
act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a
work based on the Program (independent of having been made by running the Program). Whether that is true depends
on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided
that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of
the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in exchange for a fee.
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 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 non-commercial 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
