the recipients all the rights that you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. If the software is modified by someone else and passed
on, we want its recipients to know that what they have is not the original, so that any problems in-
want its recipients to know that what they have is not the original, so that any problems in-
its recipients to know that what they have is not the original, so that any problems in-
troduced by others will not reflect on the original authors' reputations.
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 effect making the pro-
gram proprietary. To prevent this, we have made it clear that any patent must be licensed for every-
one's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0.
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 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.

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 ap-
propriate 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
