Appendix Licenses
Also, for each author's protection and ours, we want to make certain that everyone under-
stands 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 introduced by others will not reflect on the original authors' reputati-
ons.
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.
12.4.1.2 GNU GENERAL PUBLIC LICENSE
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 inclu-
ded without limitation in the term “modification”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modification are not covered by this Licen-
se; 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.
1. You may copy and distribute verbatim copies of the Program's source code as you re-
ceive 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 physical act of transferring a copy, and you may at your
option offer warranty protection in exchange for a fee.
2. 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 you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you chan-
ged the files and the date of any change.
