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.

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-

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 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
