"""
Module to ease work with nightscout profiles.
By default lists all profiles found, and supports following sub-commands:
* profiles - list defined profiles
* display - display named (or default) profile

* get - save to disk profile in OpenAPS format

Getting in openaps format seems to be buggy. It works fine in Nightscout format:
python2 get_profile.py --nightscout https://myurl.com display > ns.json

But if I select the --format openaps it seems to get grumpy. I am running Nightscout 0.11.1
python2 get_profile.py --nightscout https://myurl.com display --format openaps > ns.json

Sorry, gists aren't too good for keeping track of development, so currently this lives in https://github.com/viq/oref0/blob/profile_from_nightscout/bin/get_profile.py - are you seeing the same issue with that one?
