Overview

A Logger based Log system, with levels. See Logger for more info.

RBus::Log logs to STDOUT by default, it’s possible to redirect this output to a file by setting a filename in the environment variable $RBUS_LOG_FILE. The default log level is ERROR, this can be adjusted by setting the environment variable $RBUS_LOG_LEVEL to FATAL, ERROR, WARN, INFO or DEBUG, or by setting RBus::Log.level=(new_level)
