For example, if you distribute copies of such a program, whether gratis or for a fee,
you must give 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 modi-
fied by someone else and passed on, we want its recipients to know that 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 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 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.
TERMS AND CONDITIONS FOR COPYING, DISTRIBU-
TION 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.
