'''
Simplistic script to parse the detailed AWS billing CSV file.

Script displays cost of S3 operations broken down per region, bucket and usage 
type (either storage or network). It also sums up the amount of storage used per bucket. 
Output is filtered wrt to costs < 1$.

See http://docs.aws.amazon.com/awsaccountbilling/latest/about/programaccess.html for 
how to set up programmatic access to your billing.
