 ---Logging works as follows:
 --- - Each log message is accompanied with 2 attributes: a subsystem, and level.
 --- - After each message gets into the logger it passes (asynchronously) through a series of output filters which decide where the message will be written to.

 ---log.* API is also available from the Saved Games\DCS\Config\autoexec.cfg file so you can control log output in you local machine.
