 • -v
 	Increase verbosity level. Can be stacked up several times (-vv, -vvv, etc.) to show
 	increasingly more information during application runtime.
 • --log
 	Enables logging of runtime information into a 'log.txt' file. Verbosity level of this logging
 	matches the level set by `-v`.
+• --dump
+	Start the application in a data-dump mode, where a 'dump.dat' file is created.

 • --version
-	Show application version information
