# This file holds the implementations for all the API clients.

# If you want to develop a new client, here are some suggestions: Get the fetch
# methods working first, then the push, then the liquidsoap notifier. You will
# probably want to create a script on your server side to automatically
# schedule a playlist one minute from the current time.
