# A short script to clean up fitbitd's verbose logging, by redirecting it to a logfile.
# Created by Christopher Bowns on 2011-09-25
# Copyright 2011 Mechanical Pants Software

# here's the lowdown:
# 1. set /Library/LaunchDaemons/com.fitbit.fitbitd's StandardErrorPath to /var/log/fitbitd.log
# 2. kick launchd so it sees the new entry
# 3. install an entry in newsyslog.conf so we rotate and toss old logs periodically
