Subject: Lissage de la gestion des chemins de chargement de fichiers : -
 Option -R fait maintenant des Import à tous les niveaux de la   hiérarchie de
 répertoires. Par exemple, Require "Init.Wf" marche. - Option -I rend
 maintenant possible l'accès aux sous-répertoires via   les noms qualifiés.
 Ainsi -R est exactement comme -I sauf qu'il   rend récursivement visibles les
 noms non qualifiés. - Ajout option -I dir -as coqdir, et par symétrie, -R dir
 -as coqdir. - Ajout option -exclude-dir pour exclure certains
 sous-répertoires de   la descente récursive de -R. - Amélioration message de
 localisation pour fichiers venant d'un "state". - Adaptation du checker (et
 ajout du test check_coq_overwriting qui   semblait involontairement oublié
 dans l'option -R).
