12.2: Command syntaxThe syntax description is enclosed within angled single quotes, optional items are enclosed in square brackets, multiword items are enclosed in curly braces, and vertical bars separate different legitimate choices. For example, the documentation item for the command for drawing contours
draw contour .min. .max. .inc. ' to you,
looks like garbage to Gri. Gri will recognize it as an attempt at the
`draw contour ' command (because the first 2 words match the syntax)
but it will then get confused, spit out an error message, and quit.
