Also, for each authors 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ed 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 reect
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 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
modication follow.
Terms & conditions for copying, distribution, & modication
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 modications and/or translated into another language.
(Hereinafter, translation is included without limitation in the
term “modication.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modi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.
