+# Project: Backup and restore system files to/from home extras (system dotfiles) directory
+
+# Dependencies: None
+# NOTE: The backups will be stored in the ~/extras directory, preserving the original file structure. Run as sudo or be prompted for password
+# Example usage:
+#       To backup a specific file: root.sh --backup /some_directory/some_file.conf
+#       To restore a specific file: root.sh --restore ~/extras/some_directory/some_file.conf
+#       To restore all files: root.sh --restore
+#
+
+# Use $SUDO_USER to get the original user when run with sudo, or fall back to the current user if not
