-%% Time based rotation is configurable via `crash_log_date', the syntax is
-%% documented in the README. To control the number of rotated files to be
-%% retained, use `crash_log_count'.
+%% `crash_log_msg_size` 应用程序var用于指定最大值要记录的任何消息的大小。
+%% `crash_log_size` 用于指定崩溃日志的最大大小，然后将其旋转（0将禁用）。
+%% `crash_log_date` 基于时间的轮播可通过配置，语法为自述文件中记录了
