Language Notation

    Non-terminals: Syntactic categories
    Terminals:     Literal words and character set members

    A colon (:) following a nonterminal introduces its
    definition.  Alternative definitions are listed on separate
    lines, except when prefaced by the words "one of". An
    optional symbol is indicated by enclosing the symbol in
    brackets ([]).

    Examples:

        integer-constant:
            decimal-constant [integer-suffix]
            octal-constant [integer-suffix]
            hexadecimal-constant [integer-suffix]
    
        octal-constant:
            0
            octal-constant octal-digit

        octal-digit: one of
            0 1 2 3 4 5 6 7
