In some parts of this book we show the changes to a configuration file or C code in unified diff format. In this format, only the sections of the file that changed are shown. Lines that are prefixed with a `-' have been removed, and lines that have are prefixed with a `+' have been added. Each section is introduced by a line starting `@@'; this shows the line numbers in the new and old version of the file.

For configuration file or command examples where you encounter italicized text, it means "insert the appropriate value for your site here."
