	HelpPage string

	// AdditionalHelp will be displayed in version output.

	// Usage examples to display in USAGE section of help output.
	// Every string will be prepended with <application-name>
	// By default, the following usage example is always added:
	//    --extcap-interfaces
	//
	// As an example, adding the following lines with application name 'ciscodump':
	//    --extcap-interface=ciscodump --extcap-dlts
	//    --extcap-interface=ciscodump --extcap-config
	//    --extcap-interface=ciscodump --remote-host myhost --remote-port 22222 --remote-username myuser --remote-interface gigabit0/0 --fifo=FILENAME --capture
	// will produce the following output:
	//    ciscodump --extcap-interfaces
	//    ciscodump --extcap-interface=ciscodump --extcap-dlts
	//    ciscodump --extcap-interface=ciscodump --extcap-config
	//    ciscodump --extcap-interface=ciscodump --remote-host myhost --remote-port 22222 --remote-username myuser --remote-interface gigabit0/0 --fifo=FILENAME --capture
