#
# Description: A script used to restart services that may use Let's Encrypt-generated SSL certificates
#
# Author: Keith Muska
#
# Changelog:
# * 04/28/2017: Keith Muska
# - Initial write
# * 01/08.2020: Keith Muska
# - Previous script was missing an entire code block... It was not stopping the service, only trying to start it. Also, fixed a variable name typo
# * 15.02.2021: Nikita Shchetinin
# - Rewritten completely to make the script more simple and predictible
