# Description: | |
# Provides a basic script to automate enabling and disabling websites found | |
# in the default configuration directories: | |
# /etc/nginx/sites-available and /etc/nginx/sites-enabled | |
# For easy access to this script, copy it into the directory: | |
# /usr/local/sbin | |
# Run this script without any arguments or with -h or --help to see a basic | |
# help dialog displaying all options. | |
