Title: Adding proper syslog levels

syslogConfig.levels = {
debug: 0,
info: 1,
notice: 2,
warning: 3,
error: 4,
crit: 5,
alert: 6,
emerg: 7
};

It is exported with the Config var.
Usage:

var winston_log = require('winston-syslog').Syslog;
var syslog_config = require('winston-syslog').Config;
var winston = require('winston');

winston.add(winston.transports.Syslog);
winston.setLevels(syslog_config.levels);
