TODO: update doc
Base configuration file to configure a station on liquidsoap.
# Interactive elements:
An interactive element is accessible to the people, in order to:
- get metadata
- skip the current sound
- enable/disable it
# Element of the context
We use theses elements from the template's context:
- controller: controller describing the station itself
- settings: global settings
# Overwrite the template
It is possible to overwrite the template, there are blocks at different
position in order to do it. Keep in mind that you might want to avoid to
put station specific configuration in the template itself.

An interactive source is a source that:
- is skippable through the given id on external interfaces
- can be disabled
- store metadata

A stream is a source that:
- is a playlist on random mode (playlist object accessible at {id}_playlist
- is interactive
