# Send Game Day its calendars from a computer, instead of typing long links with the remote. One calendar per line
# in calendars.txt beside this script (or the file you name): "sport | name | link", optionally "| colour". It
# replaces the list on the TV, waits while the TV fetches each calendar, and prints how each one loaded. Links are
# never printed. Install the add-on first (README.md).
