what they have is not the original, so that any
problems introduced by others will not reflect on
the original authors’ reputations.
Finally, any free program is threatened constant-
ly by software patents. We wish to avoid the
danger that redistributors of a free program
will individually obtain patent licenses, in effect
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 modification follow.

0. This License applies to any program or other
work which contains a notice placed by the
copyright holder saying it may be distribu-
ted under the terms of this General Public Li-
cense. 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. (Herei-
nafter, 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 (inde-
pendent of having been made by running the
Program). Whether that is true depends on what
the Program does.
You may copy and distribute verbatim co-
1.
pies 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 phy-
sical act of transferring a copy, and
you may at your option offer war-
ranty protection in exchange for a fee.
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
