+# Autor: Radoslaw Karasinski, Artur 'stefopl' Stefanski
 # Usage: you can pass following arguments:
 #   --mikrus MIKRUS_NAME (i.e. 'X123')
 #   --user USERNAME (i.e. 'root')
 #   --port PORT_NUMBER (to configure connection for non mikr.us host)
 #   --host HOSTNAME (to configure connection for non mikr.us host)
 #   [email protected] (without param in front)
