 ## Architecture of the engine
 The engine consists of the core engine (`base` dependency in your project) and various subsystems (`slf4j-compat`, `windowing`, etc.). \

 It contains among other things a default logger implementation, useful methods, event system and a placeholder system. \

 Subsystems on the other hand usually handle complex tasks. They provide abstractions for libraries and operating system calls. \
