# Il permet d'utiliser sudo en gardant le $PATH modifié

# ynh_use_nodejs active une version de nodejs dans le script courant
# 3 variables sont mises à disposition, et 2 sont stockées dans la config de l'app
# - nodejs_path: Le chemin absolu de cette version de node
# Utilisé pour des appels directs à node.
# - nodejs_version: Simplement le numéro de version de nodejs pour cette application
# - nodejs_use_version: Un alias pour charger une version de node dans le shell courant.
# Utilisé pour démarrer un service ou un script qui utilise node ou npm
# Dans ce cas, c'est $PATH qui contient le chemin de la version de node. Il doit être propagé sur les autres shell si nécessaire.
