Usage: $0 ~/myopenaps http://mynightscouthost.herokuapp.com
If you have day-of-the-week autotune profiles named like
"myopenaps/autotune/profile-day0.json", copies the profile for whichever day
today is to myopenaps/autotune/profile.json and reruns autotune. Day 0 is
Sunday, day 1 is Monday, etc.

This script is not used by a default install.
