Prints the string 'str' to the output device, appending a line return. The message is reformatted as appropriate to the particular diplaying device, where 'flind' and 'ind' are used as hints for performing that operation. However, any newlines appearing in 'str' are respected. The output device may not display the string until flush() is called. Some implementations may automatically flush when this method is called. This method just prints the string, the string does not make part of a "message" in the sense that no severity is associated to it.
