# Class/logger specific thresholds now.
# Ones for which threshold is not specified will use root logger's DEBUG level
# Use stricter levels for loggers that you want to shut up

# console.log() just as qDebug() goes to logger called "Qt" and uses level DEBUG.
# So setting it to INFO would suppress
# console.log() messages
