# Ubuntu 12.10 based web server installation script
# Run this by executing the following from a fresh install of Ubuntu 12.10 server:
# 
#     bash -c "$(curl -fsSL https://raw.github.com/gist/4372049)" <mysqlPassword>
# 
# Be sure to replace <mysqlPassword> with your intended MySQL Password.
# Also, run this as root, unless you enjoy failing.
# 
# Its handy to install 'screen' if you want to ensure your remote connection to
# a server doesn't disrupt the installation process. If you want to do this, just
# do the following before running the main bash command:
# 
#     apt-get install screen -y
#     screen
# 
# To recover your session if you are disconnected, ssh to your server as root again,
# and type:
# 
#     screen -x
# 
# Dependencies:
# - curl
# 
# Todo:
# - SSL Configuration
