Usage: ${SCRIPT} [-dhnv] 

 $SCRIPT v${SCRIPT_VERSION} - Generate command-output-list to attach to bug report
 
where:
    -d          Enable script-(d)ebug output
    -h          Display this (h)elp and exit
    -n          no-do: list-to-screen but don't run the commands
    -v          Enable (v)erbose mode. Can be used multiple times for increased
                 verbosity.
                 
Typical Use Cases:

	${SCRIPT}      		# run commands and write report file
	
EOF
	exit ${ERROR_LEVEL}
