# XDG Base Directory Specification

# Sets up necessary environment variables for XDG convention,

# Thank you remeberYou for the idea

# Additionally, home directories are set using the XDG specification,
# if the xdg-user-dirs module is enabled.

# Shellcheck will complain about setting permissions for the directories
