<para>
	This format supports the .sdf files from the Suunto product family
	'Suunto Trek Manager', 'Suunto Ski Manager' and 'Suunto Sail Manager'.
	The contents of the sdf file depends on the used product and can
	be one route or one track. Thatswhy when you want to use sdf on the
	output side you have to use the
	<link linkend="Route_And_Track_Modes">-r OR the -t</link> option. This will tell
	GPSBabel which type of data should be written.
