   Usage: $(basename $0) [Options]

      Script creates a MySQL database. The database name is either given on command
      line using parameter '-d' or will be asked for otherwise.

   

      Options:

      -d <db-name>
            The name of the domain, which is requested for deletion. If not set, script
            will ask for the database name.

      -I
            Non-interactive mode. Script will act in non-interactice mode. At least the
            database name must be given using parameter '-d'. Default is acting in 
            interactive mode

      -p <db-passwd>
            Password for the given user. If not set, script looks for a file named 
            'databases/<db-name>'. If found, script reads database password from that file. 
            If not running in quiet mode, you will be asked to confirm or set the db-user.
      -q
            Be quiet. Setting this parameter implies non-interactive mode (parameter -I). So 
            if '-q' is set, at least the database name must be given using parameter '-d'.

      -u <db-user>   
            The name of the database user who will be granted full access to the given 
            database. If not set, script looks for a file 'databases/<db-name>'. If 
            found, script reads database settings (user/password) from that file. If not 
            running in quiet mode, you will be asked to confirm or set the db-user.
