# Script: replace_confs.py
# Author: George McCabe, November 2019
# Description: Utility used to rename configuration variables in the METplus
#  wrappers. Modify the script to set the list of directories to search and
#  the dictionary containing the list of variables to replace. The script
#  prints a list of commands to the screen. These commands can be run to
#  find and replace all instances of the configuration variable listed.
#  After running the commands, review 'git diff' to make sure that all of
#  the changes are intended. For each change, documentation needs to be
#  updated to list the new configuration variable name and deprecate the old
#  name.
