# File:
# nginx_modsite
# 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.
