RSpec, Capybara and AuthLogic

This gist is dedicated to all of my fellow clueless n00bs who are frightened by the combination of [RSpec][1], [Capybara][2] and [Authlogic][3].

This gist will not tell you how to install Ruby, Rails, RSpec, Capybara or Authlogic. For the most part, you can install any of these by running either:

brew install <packagename>
bundle install <packagename>

At the point in time that you reach this gist, you should have all of them installed.

#In early development, sometimes you've got a hand-built instance, but you also don't want to leave it up all the time
# We've got an m4xl instance running Spinnaker (http://spinnaker.io) but we only really need it during the day
# As a cost-saving measure, we shut it down overnight.  However, we want it to be consistently accessible
# So this script is in a Jenkins job that runs every morning, 
# starting up the instance then updating its DNS record to the new IP.

#If you have multiple DNS records for a single instance, 
# you can safely run a second copy of the script with the ZONEID and RECORDSET updated appropriately.
