- * This class wraps an output stream, replacing all occurrences
- * of <CR><LF> (carriage return followed by a linefeed),
- * which is the NETASCII standard for representing a newline, with the
- * local line separator representation. You would use this class to
- * implement ASCII file transfers requiring conversion from NETASCII.
- * <p>
- * Because of the translation process, a call to <code>flush()</code> will
- * not flush the last byte written if that byte was a carriage
- * return. A call to {@link #close close() }, however, will
- * flush the carriage return.
