the software is modified by someone else and passed on, we want its re-
cipients to know that what they have is not the original, so that any pro-
blems introduced by others will not reflect on the original authors‘ re-
putations.
Finally, any free program is threatened constantly by software patents.
We wish to avoid the danger that redistributors of a free program will in-
dividually obtain patent licenses, in effect making the program propri-
etary. To prevent this, we have made it clear that any patent must be li-
censed for everyone‘s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modifica-

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICA-
TION
0. This License applies to any program or other work which contains a
notice placed by the copyright holder saying it may be distributed un-

depends on what the Program does.
1. You may copy and distribute verbatim copies 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 recipi-
ents 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
