+The copy included here is the Debian Stretch default file for the **ROOT user**.
+Copying the default file resets the root user's profile to a baseline state and
+ensures they pull their initial custom settings from the modified
+*/etc/bash.bashrc* found in this archive.  If you ever need to reset your root
+user's profile, simply copy this file.
