They should be set to an attribute set of respective configurations. They should be set to an attribute set of respective configurations.
Alternatively, the configurations can be functions, in which case those
functions will be passed `autoloadArgs` and must return a standard
configuration (this is useful when using autoloads with the `nixDir` feature).
