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 included without limitation in the term ``modification''.) -Each licensee is addressed as ``you''. - -Activities other than copying, distribution and modification are not -covered by this License; 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. - -\item 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 - 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. - -\item -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: - -\begin{enumerate} - -\item -You must cause the modified files to carry prominent notices stating that -you changed the files and the date of any change. - -\item -You must cause any work that you distribute or publish, that in -whole or in part contains or is derived from the Program or any -part thereof, to be licensed as a whole at no charge to all third -parties under the terms of this License. - -\item -If the modified program normally reads commands interactively -when run, you must cause it, when started running for such -interactive use in the most ordinary way, to print or display an -announcement including an appropriate copyright notice and a -notice that there is no warranty (or else, saying that you provide -a warranty) and that users may redistribute the program under -these 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 such an announcement, your work based on -the Program is not required to print an announcement.) - -\end{enumerate} - +everyone understands 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' reputations. -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works.
