### Le fichier de configuration { #the-config-file }

En repartant de l'exemple précédent, votre fichier `config.py` pourrait ressembler à :

### Properties of pre-incubation features

Properties of pre-incubation features MUST start with `org.gradle.experimental.`  
They can all be called **experimental properties**.

The qualifier clearly indicates to users that the feature is still in early development and not yet stable.

Experimental properties MUST be stable.
