La mise en page DLFP casse toute l'indentation, mais le code reste lisible.

Si une action a été faite (purge d'un paquet, etc..), on peut relancer le script afin de voir si il n'y a pas d'autres actions à refaire (par exemple, un nouvel orphelin). Je dois l'améliorer pour intégrer cela dans une boucle, mais ce n'est pas une de mes priorité actuelle.
