Automated setup script for OS X Server 5.0.x and later

gistfile1.txt

#!/bin/bash

# This script is designed to automate the setup of OS X Server 5.0.3 and later
# by authorizing and using the 'server' tool within /Applications/Server.app to
# run the initial setup and configuration of OS X Server's services.

# Script will check for the existence of the 'server' setup tool. If the 'server' setup tool
# is not located where the script expects it to be, the script will exit.

# the initial setup and configuration of OS X Server's services.
