Cronolog日志文件处理工具使用

cronolog is a simple program that reads log messages from its input and writes them to a set of output files, the names of which are constructed using template and the current date and time.

Cronolog是一个小巧高效的日志文件处理工具，可以实现自动的按规则生成周期性的日志文件。我们以对Apache access log和Tomcat运行日志的处理为例进行说明。
