+/*!
+ * \brief The RollingFileAppender class extends FileAppender so that the underlying file is rolled over at a user chosen frequency.
+ *
+ * The class is based on Log4Qt.DailyRollingFileAppender class (http://log4qt.sourceforge.net/)
+ * and has the same date pattern format.
+ *
+ * For example, if the fileName is set to /foo/bar and the DatePattern set to the daily rollover ('.'yyyy-MM-dd'.log'), on 2014-02-16 at midnight,
+ * the logging file /foo/bar.log will be copied to /foo/bar.2014-02-16.log and logging for 2014-02-17 will continue in /foo/bar
+ * until it rolls over the next day.
+ *
+ * The logFilesLimit parameter is used to automatically delete the oldest log files in the directory during rollover
+ * (so no more than logFilesLimit recent log files exist in the directory at any moment).
+ * \sa setDatePattern(DatePattern), setLogFilesLimit(int)
