I understood the meaning of "is derived from" to be "using the source code to make a derivative of" as opposed to "using the services of". If I use libc, I don't think I am creating a libc. Unless I am, I'm not deriving, I think. If I use libc, I simply use the services. Hence, libc is "a section of" the thing I am making, and does not derive from it. How is this wrong? Is it "strategic" to look at sections as derivations? -Jim
