module AWS

  # Provides an expressive, object-oriented interface to Elastic Load 
  # Balancing (ELB).
  #
  # == Credentials
  #
  # You can setup default credentials for all AWS services via
  # AWS.config:
  #
  #   AWS.config(
  #     :access_key_id => 'YOUR_ACCESS_KEY_ID',
  #     :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')
  #
  # Or you can set them directly on the ELB interface:
  #
  #   elb = AWS::ELB.new(
  #     :access_key_id => 'YOUR_ACCESS_KEY_ID',
  #     :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')
  #
