Conventions This guide uses the following conventions:

Italic text	Italicized text is used to emphasize information.
CTRL+C	Key combinations are indicated by keyboard key names and a plus sign,
	all of which are in small caps sans serif text. In the example given to the
	left, press and hold down the CTRL key and press C.
Bold Courier text	Bold Courier text is used for commands and for system input that you
	type exactly as shown.
<value>	Angle brackets in a command indicate that the word contained within
(angle brackets)	must be substituted with an actual value (do not type the angle brackets).
	In the following example, replace <filename> with the actual name of
	the file:
	check_release <filename>
[parameter]	Square brackets in a command indicate that the parameter contained
(square brackets)	within is optional. In the following example, the module parameter is
	optional (often, optional parameters contain angled brackets indicating
	that the word must be substituted with an actual value):
	logcf get [<module>]
(vertical bar)	A vertical bar in a command is used between items in a list to indicate that
	you choose one of the items. For example, the vertical bar in the
	command below means you can use either the -uor the -qoption (or
	neither since this choice is also optional):
	swipplumb [-u-q]
Courier text	Courier text is used for messages or program output that appears on your
	screen.
