|

# 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.
