Instance Method Details

#configure! ⇒ Object

Provide base functionality to configure all modules. The behaviour is as follows:

1 - Check if a file named data/$CLASS$.rb exists; if so, load that file as the base configuration, i.e. “Treat.$CLASS$”; e.g. “Treat.core”

2 - Check if a folder named data/$CLASS$ exists; if so, load each file in that folder as a suboption of the main configuration, i.e. “Treat.$CLASS$.$FILE$”; e.g. “Treat.workers”

(where $CLASS$ is the lowercase name of the concrete class being extended by this.)
