      This script is used to sync webpanel updates and provide an easy
      way for users to keep their webpanel up to date with new features
      that are released - note that the first time you use this to migrate
      to the new webpanel contents, your Config.php file (containing locale
      settings) will be backed up to the $NOAA_HOME/bak/ directory and a
      replacement config.php put in its place. You can reference values you
      might have configured in the backup file to update $WEB_DIR/config.php
      to your liking.

      If you have made significant changes to any of the contents in the webpanel
      deployment, they likely WILL be destroyed by running this script as all
      files in $WEB_DIR are replaced with the exception of the following, which are
      left alone to preserve the captures:

        * audio/
        * images/
        * meteor/
