Finally, any free program is threatened constantly by software patents. We wish to avoid the
danger that redistributors of a free program will individually obtain patent licenses, in e ect
making the program proprietary. To prevent this, we have made it clear that any patent must be
licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modifi cation follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFICATION
1. This License applies to any program or other work which contains a notice placed by the
copyright holder saying it may be distributed under the terms of this General Public License.
The “Program”, below, refers to any such program or work, 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 modifi cations
and/or translated into another language. (Hereinafter, translation is included without limitation
in the term “modifi cation”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modifi cation 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.
2. 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
o er warranty protection in exchange for a fee.
3. 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 modifi cations or work under the terms
of Section 1 above, provided that you also meet all of these conditions:
1) You must cause the modifi ed fi les to carry prominent notices stating that you changed
the fi les and the date of any change.
2) 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.
3) If the modifi ed 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 modifi ed work as a whole. If identifi able 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
