# Autobot: create, setup and deploy Hubot on Heroku with Campfire adapter.
#
# USAGE:
#   autobot.sh <path>
#
# Autobot will;
#   1. download and install all the Hubot machinery
#   2. create your very own Hubot instance
#   3. create and configure a new Heroku app for you
#   4. assist you setting–up all that Campfire gibberish
#   5. give Hubot some brain if you have a validated Heroku account
#
# Sit back and relax while Autobot handles your Hubot assembly...
#
# DEPENDENCIES:
#   Heroku Toolbelt (heroku)
#   Node Packaged Modules (npm)
#   Xcode Command Line Tools (make)
#   Git SCM (git)
