Configuration syntax

The configuration is kept in the config file in the daemon working directory, and it’s going to get loaded automatically. If there isn’t one, the daemon is going to start with sane defaults, listening on localhost. The syntax for options is like follows: group.option = value or group.action(parameters). You can also comment using a -- prefix.

A simple example would be to load static hints.
{{{
modules = {
        'hints' -- no configuration
}

}}}
