The log manager is responsible for keeping a trace of all the messages the application could send as debug output. Such information is not useful most of the cases but could become crucial in some cases. Thus there are different levels of activation for the log manager to work. The log manager forwards each log request to its registered log listeners that effectively do the log the way they want (be it a status window, a console, a file, whatever). See ILogListener for more details.
