## Packages

- The logging API of the Log4j project.  
Library and application code can log through this API.  
It contains a simple built-in implementation (`SimpleLogger`) for trivial use cases.  
Production applications are recommended to use Log4j API in combination with a fully-fledged implementation, such as Log4j Core.
