*-l* 'filename'::
This option writes the output messages to a log file instead of standard output.
+*--verbose* 'level'::
+ Set the log level. Supported log levels are "none", "critical", "error", "warning",
+ "info", "debug", "all" or their identifiers "0", "1", "2", "3", "4", "5", "6". Setting the log
+ level to specific value enables all logs from that and all previous levels.

+ Example: enable all critical, error and warning logs
