In the syntax descriptions in this manual, the following notation conventions apply.

Text in teletype is literal. Text in italics, enclosed between angle brackets, like <word> should be substituted by something else.

Anything enclosed in brackets ([ ]) is optional. If something is followed by an asterisk (*) it may be repeated any number of times, such that it occurs one or more times; a combination of brackets and an asterisk ([ ]*) indicates zero or more occurrences. A bar (| ) means `or', and a colon (:) indicates that the expression to the right of it defines the expression to its left.

All commands except the bye command should be terminated with a semicolon.
