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 sof-
tware. If the software is modified by someone else and passed on,
we want its recipients to know that what they have is not the origi-
nal, so that any problems introduced by others will not reflect on the
original authors‘ reputations.
Finally, any free program is threatened constantly by software pa-
tents. We wish to avoid the danger that redistributors of a free pro-
gram 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 mo-
dification follow.

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 Pro-
gram“ means either the Program or any derivative work under copy-
right 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 limi-
tation 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 run-
ning the Program is not restricted, and the output from the Program
