Here is another version to play with. This adds a colored logger by default and makes it easy to enable a debug mode which prints HTTP wire traces.

#!/usr/bin/env ruby

# silence warnings from pry, these are normally autoloaded by aws-sdk
require 'nokogiri'
require 'json'
require 'uuidtools'

require 'aws-sdk'
require 'logger'
require 'pry'

AWS.config(
  logger: ENV['NO_LOG'] ? nil : Logger.new($stdout),
  log_formatter: AWS::Core::LogFormatter.send(ENV['LOGGER'] || 'colored'),
  http_wire_trace: !!ENV['DEBUG'] || $DEBUG)

Pry.config.prompt = [proc { "AWS> " }, proc { "AWS| " }]

Nice, thanks!
