class Console::Logger

def self.default_log_level(env = ENV)

https://mislav.net/2011/06/ruby-verbose-mode/ has more details about how it all fits together.
You can also specify CONSOLE_LEVEL=debug or CONSOLE_LEVEL=info in environment.
Set the default log level based on `$DEBUG` and `$VERBOSE`. 
def self.default_log_level(env = ENV)
	if level = env["CONSOLE_LEVEL"]
		LEVELS[level.to_sym] || level.to_i
	elsif $DEBUG
		DEBUG
	elsif $VERBOSE.nil?
		WARN
	else
		INFO
	end
end
