 # FUTURE OFFICIAL HELPERS
 #=================================================
 
-# Check if a permission exists
-#
-# While waiting for this new helper https://github.com/YunoHost/yunohost/pull/905
-# We have to use another one because the new helper use a new YunoHost command, not available for now.
-#
-# usage: ynh_permission_has_user --permission=permission --user=user
-# | arg: -p, --permission - the permission to check
-# | arg: -u, --user - the user seek in the permission
-#
-# example: ynh_permission_has_user --permission=main --user=visitors
-#
-# Requires YunoHost version 3.7.1 or higher.

-    local permission
-    local user
-    # Manage arguments with getopts
