# - in the log file and on the user's terminal in debug '-d' mode via 'DebugPrint'
# - in the log file and on the user's terminal in verbose '-v' mode via 'LogPrint'
# so that the info that is shown on the user's terminal (hopefully) looks consistent.
# This distinction matches the same kind of distinction in the
