		Usage: $prog COMMAND [OPTIONS]

		This is a helper for MariaDB upgrade.

		COMMANDS:
		  --detect                  Detect installed MySQL fork properties.
		                            Requires: running MySQL (may start it).
		  --dump-all-databases      Backup all databases (mysqldump).
		                            Requires: running MySQL.
		  --check-tables            Check all tables consistency (mysqlcheck).
		                            Requires: running MySQL (will restart it).
		  --check-package-manager   Check package manager configuration (e.g. package excludes).
		  --create-repo             Create or update system package manager repository
		                            for the target version.
		  --upgrade-packages        Upgrade system packages to the target version.
		                            Expects: stopped MySQL.
		  --upgrade-tables          Upgrade all tables structure (mysql_upgrade).
		                            Also ensures proper configuration.
		                            Requires: running MySQL.
		  --help                    Show this help message

		OPTIONS:
		  --type NAME               Set target or current MySQL fork name (expected: 'mariadb')
		  --version VERSION         Set target or current MySQL fork version (e.g.: '10.6')
