Gestion de fichiers ini avancée

Commenter

Contenu du snippet

Ce code permet de lire des fichiers ini et d'éffectuer des opérations avancées comme:
la suppression de clées
la supressions de sections
l'énumération des sections
l'énumération des clées d'une section (nom + (=valeur optionnelle)
l'écriture manuelle d'une section

Le fonctionnement est très simple et je ne crois pas avoir besoins de donner des explications ;-). Dîtes-moi le si vous en voullez.
