If there is no configuration file in “$XDG_CONFIG_HOME/update-mirrors”, try looking through directories specified in XDG_CONFIG_DIRS. If XDG_CONFIG_DIRS is not specified, use “/etc/xdg”. Now config files are searched for in this order: - “$XDG_CONFIG_HOME/update-mirrors/config.sh”, or “$HOME/.config/update-mirrors/config.sh” if XDG_CONFIG_DIR is not defined. - For each DIR in XDG_CONFIG_DIRS “$DIR/update-mirrors/config.sh” is tried, or “/etc/xdg/update-mirrors/config.sh” if XDG_CONFIG_DIRS is not defined.
