# Logging
# =========
# Standard used for logging levels in novelWriter:
# CRITICAL Use for errors that result in termination of the program
# ERROR Use when an action fails, but execution continues
# WARNING When something unexpected, but non-critical happens
# INFO Any useful user information like open, save, exit initiated
# ----------- SPAM Threshold : Output above should be minimal -----------------
# DEBUG Use for descriptions of main program flow
# VERBOSE Use for outputting values and program flow details
#
# Add verbose logging level
VERBOSE = 5
