Newly introduced terms are typically emphasized using an italic font the first time they appear. Command line dialogues, source code fragments, and in some cases identifiers borrowed from program source code are printed using a monospaced font.

Tables or figures that are referred to but not yet defined are indicated by double question marks, ??, in the text, and a small square box [*] in the online version; such missing references can be found in the document sources by searching for the string FIXME.
