Syntax diagram for input directives

Where the actual symbols, [ ] and { }, are used, they are part of the syntax and must be present when the directive is specified.

Where symbols [ and ] (larger and in bold) appear, the material enclosed is optional.

Where the symbols { and } (larger and in bold) appear, multiple occurrences of the material enclosed are permitted.
