AppendicesA-4Activities other than copying, distribution and modification are not coveredby this License; they are outside its scope. The act of running the Program isnot restricted, and the output from the Program is covered only if its contentsconstitute a work based on the Program (independent of having been madeby running the Program). Whether that is true depends on what the Programdoes.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 this Licenseand to the absence of any warranty; and give any other recipients of theProgram a copy of this License along with the Program.You may charge a fee for the physical act of transferring a copy, and you mayat 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 suchmodifications or work under the terms of Section 1 above, provided that youalso meet all of these conditions:a) You must cause the modified files to carry prominent notices stating thatyou changed the files and the date of any change.b) You must cause any work that you distribute or publish, that in whole orin part contains or is derived from the Program or any part thereof, to belicensed as a whole at no charge to all third parties under the terms of thisLicense.c) If the modified program normally reads commands interactively when run,you must cause it, when started running for such interactive use in the mostordinary way, to print or display an announcement including an appropriatecopyright notice and a notice that there is no warranty (or else, saying thatyou provide a warranty) and that users may redistribute the program underthese conditions, and telling the user how to view a copy of this License.(Exception: if the Program itself is interactive but does not normally print suchan announcement, your work based on the Program is not required to printan announcement.)These requirements apply to the modified work as a whole. If identifiablesections of that work are not derived from the Program, and can bereasonably considered independent and separate works in themselves,then this License, and its terms, do not apply to those sections when youdistribute them as separate works. But when you distribute the same sectionsas part of a whole which is a work based on the Program, the distributionof the whole must be on the terms of this License, whose permissions forother licensees extend to the entire whole, and thus to each and every partregardless of who wrote it.
