(Hereinafter,translation is included without limitation in the term "modification".)Each licensee is addressed as "you".Activities other than copying, distribution and modification are notcovered by this License; they are outside its scope. The act of runningthe Program is not restricted, and the output from the Program is coveredonly if its contents constitute a work based on the Program (independentof having been made by running the Program). Whether that is true dependson what the Program does.1. You may copy and distribute verbatim copies of the Program's source codeas you receive it, in any medium, provided that you conspicuously andappropriately publish on each copy an appropriate copyright notice anddisclaimer of warranty; keep intact all the notices that refer to thisLicense and to the absence of any warranty; and give any other recipientsof 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 youmay at your option offer warranty protection in exchange for a fee.2.

If identifiablesections of that work are not derived from the Program, and can bereasonably considered independent and separate works in themselves, thenthis License, and its terms, do not apply to those sections when youdistribute them as separate works.
