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:
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 thereof, to
be licensed as a whole at no charge to all third
parties under the terms of 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
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:
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,
a)
b)
c)
a)
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
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.
